National Highway Traffic Safety Administration (NHTSA), U.S. Department of Transportation (DOT).
Final rule; response to petition for reconsideration.
This final rule denies most aspects of a petition for reconsideration of a February 27, 2012, final rule that expanded the applicability of the Federal motor vehicle safety standard for child restraint systems to child restraints sold for children weighing up to 36 kilograms (kg) (80 pounds (lb)). The petition stated, among other things, that a label that was required by the 2012 rule for certain child restraints was unclear and could be misunderstood. In response, NHTSA is making minor adjustments to the labeling requirement to make it clearer and more reader-friendly. For a year, manufacturers have the option of meeting the requirements of the February 27, 2012 rule or the rule as modified today. All other requests for substantive changes to the 2012 rule are denied.
Effective date: The amendments made by this final rule are effective February 27, 2014.
Compliance dates: The compliance date of the amendments of this final rule is February 27, 2015. Optional early compliance is permitted. Accordingly, child restraints manufactured on or after February 27, 2014 until February 26, 2015, may comply by meeting either the requirements specified in the February 27, 2012, final rule (77 FR 11626) or those requirements as amended by today's final rule. Child restraints manufactured on or after February 27, 2015 must meet the requirements as amended by today's final rule.
If you wish to petition for reconsideration of this rule, your petition must be received by April 11, 2014.
If you wish to petition for reconsideration of this rule, refer in your petition to the docket number of this document and submit your petition to: Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue SE., West Building, Washington, DC 20590.

V. Rulemaking Analyses and Notices
This final rule denies most aspects of a petition for reconsideration of a February 27, 2012, final rule (77 FR 11626) that expanded the applicability of Federal Motor Vehicle Safety Standard (FMVSS) No. 213, “Child restraint systems,” from child restraint systems (CRSs) for children weighing up to 65 lb to CRSs for children weighing up to 80 lb. The final rule also adopted use of a 10-year-old child (10YO) test dummy (HIII-10C) to test CRSs manufactured for children weighing 65 to 80 lb. The test dummy weighs about 78 lb.
Generally speaking, in NHTSA's compliance test for FMVSS No. 213, NHTSA has the choice of assessing the performance of a CRS when installed on a bench seat by way of the simulated lower anchorages of the “child restraint anchorage system” 
of the standard seat assembly or by a seat belt. That is, child restraint manufacturers must ensure that their products meet the requirements of FMVSS No. 213 when NHTSA tests the CRS attached by the child restraint anchorage system connectors and when the agency tests the CRS attached by the seat belt. During the course of this particular rulemaking, the Alliance of Automobile Manufacturers (Alliance) submitted a comment 
on an aspect of the rulemaking proposal relating to how NHTSA would use the 10YO dummy in compliance tests, particularly with respect to an issue concerning attaching CRSs by the child restraint anchorage system.
The Alliance pointed out that the child restraint anchorage system was developed by NHTSA to withstand crash forces in a crash generated by a mass on the system of 65 lb (mass of child plus that of CRS).
Given such a design parameter, the group stated that vehicle manufacturers would never recommend that a CRS be installed using the vehicle child restraint anchorage system when used to restrain Start Printed Page 10397children represented by the 10YO dummy (the dummy alone weighs about 78 lb). Subsequently, the Alliance and the Association of Global Automakers (Global Automakers) submitted a joint comment stating that “review of the actual supporting test data and load calculations reveals that the LATCH load requirements were developed using a combined maximum child+CRS weight of 65 pounds.”  The vehicle manufacturer groups also expressed concern about “a trend toward increased weight of child restraints . . . [that] could call into question the validity of the 48 pound estimate for appropriate maximum child weight capacity.” 
The information from the vehicle manufacturers was important to NHTSA in determining how we should use the new 10YO test dummy in compliance testing. After assessing all available information, NHTSA decided that it would not subject child restraints with internal harnesses to compliance testing using the 10YO test dummy while the CRS is attached by the child restraint anchorage system anchorages, since that scenario would be contrary to vehicle manufacturers' instructions for using child restraint anchorage systems and inconsistent with the design parameters of the anchorage system.
Furthermore, the agency determined that, given that NHTSA will not test a child restraint with the child restraint anchorage system on the standard seat assembly using the 10YO dummy for the above reasons, there is a need to inform consumers on the use of child restraint anchorage systems to reduce the likelihood that a CRS would be used in a manner that is inconsistent with the assessed performance of the harness-equipped CRS and the design limits of child restraint anchorage systems. Some new harness-equipped CRSs have been produced that are heavier than all CRSs made in the past, and some are recommended for children weighing more than 48 lb.
In the 2012 final rule, we adopted a labeling instruction informing consumers not to use the child restraint anchorage system when restraining a total weight of more than 65 lb.
NHTSA determined that a label is needed to reduce the likelihood that consumers will use the child restraint anchorage system lower anchorages with a child+CRS weight that is too heavy for the anchorages, which would pose an unreasonable risk of overloading the vehicle anchorage system in a crash. Overloading the vehicle lower anchorages could be catastrophic for the child occupant, as the CRS could dislodge from the vehicle seat. The instruction provided a clear and consistent message regarding the use of the child restraint anchorage system and improved the current situation where consumers are provided inconsistent or no information about the child weight limit for the lower bars. The information helps to ensure that the child restraint anchorage systems (particularly the lower anchorages) are used in a manner that comports with the design parameters of the vehicle system.
II. Petition for Reconsideration
NHTSA received a petition for reconsideration on the label from several consumer advocates.
The petitioners did not oppose informing consumers of the weight limits of the lower anchorages per se, but instead did not support a 65 lb limit. They requested that the 65 lb combined weight should be increased to 80 to 85 lb, believing this is needed to “preserve the extended use of lower anchors.”
Petitioners believe that when NHTSA developed FMVSS No. 225, the agency referred several times in the preamble to a child weight of 65 lb. Petitioners “surmise that FMVSS 213 [sic] rule was for anchors to be strong enough to accommodate [CRSs] that would in themselves weigh at least 15, possibly 20 pounds, which implies a combined weight of at least 80 to 85 lbs.” The petitioners state that “the decision to adopt 65 pounds as the combined maximum weight . . . will unnecessarily restrict the use of the LATCH system and force caregivers back to using seat belts for anchoring forward-facing [CRSs].” The petitioners also state that their intent in petitioning for reconsideration of the rule was to “minimize the likelihood that vehicle manufacturers will apply the same formula” to tether anchorages.
a. The Label
A number of persons sent letters or met with NHTSA in support of the petition for reconsideration or to ask questions about the labeling requirement.
Several suggest that NHTSA suspend the requirement for the label, increase the 65 lb combined weight limit on the label, or require vehicle manufacturers to increase the strength of child restraint anchorage systems to accommodate a higher combined weight. Several letter writers express the view that the final rule should have addressed tether weight limits.
Several of the letters and other submissions are summarized below.
Representatives from the Dorel Juvenile Group (Dorel) and others met with NHTSA to express their view that the new labeling requirement reduces use of child restraint anchorage systems. They believe that the current status quo (current recommendations and practice) is to use child restraint anchorage systems for installing child restraints with internal harnesses for a child weight up to 48 lb. They also add that child safety seats now weigh between 15 to 33 lb, so the new label would exclude the use of child restraint anchorage systems for a “large” number of children who are still in harnessed-CRSs. They state that because child restraint anchorage systems are easier to use and have a higher rate of correct installation than seat belts, a child restraint anchorage system installation is safer than a belt installation. They suggest that in the short term, NHTSA should suspend the new label requirement, and that in the long term, NHTSA should increase the strength of the child restraint anchorage system.
Safe Ride News (SRN) wrote in a letter that the agency should suspend the labeling requirement because the label will “cause a lot of confusion” and affect public perception of the safety of child restraint anchorage systems “without improving actual safety in any significant way.” The letter writer believes that public education messages Start Printed Page 10398will become “extremely muddied due to the variability from CR [child restraint] to CR.” SRN also states its concern that “lower-anchor weight limits will spill over to tether-anchor weight limits.” Further, in another letter, SRN suggests that NHTSA require a child-weight limit of 50 lb as a “compromise” that “eliminates the formula of child-weight plus CR-weight.” Under SRN's suggestion, child restraint manufacturers may set their own weight limits for the use of child restraint anchorage systems up to that ceiling with a possible lower weight limit for extremely heavy child restraint models.
The Juvenile Products Manufacturers Association (JPMA) submitted a letter in support of Dorel's submission and Safe Ride News' letter, repeating many points of earlier correspondence.
Those points include that the extended use of lower anchorages should be preserved; that use of tethers should be increased; that efforts should be made to minimize the likelihood that vehicle manufacturers will similarly restrict tether anchor use; that parents might not remember or even initially know to switch to the seat belt during the several-year course of a CRS's use; and, that innovation by CRS manufacturers to reduce loads on anchors through energy management features should be supported. JPMA also expressed the view that NHTSA should suspend the label and “consider strengthening the anchorage strength requirements of FMVSS 225 immediately.” In a later submission, JPMA states that the label will result in “lack of trust in LATCH” because it results in varying weight limits, and in some cases weight limits lower than the 40 or 48 lb currently used in the field. JPMA also believes that the label will lead to early graduation to boosters due to the wording on the label and because CRSs might not achieve a tight fit with a seat belt or may be too difficult to install with a seat belt.
An individual, Alisa Baer, wrote that introducing “strict lower anchor weight limits of CR + child = 65 pounds will further complicate” child restraint anchorage systems. The letter writer states that parents typically do not understand how fast a child grows and that a parent may opt not to use a CRS when their child is on the cusp of the weight limit out of fear that the child will soon outgrow the CRS, when in reality the child could have much more time before exceeding the weight limit. The writer states that “ugly numbers—like 37 or 41 [lb]—are scary to parents & technicians,” and “will likely erode confidence in the LATCH system” because people may “[think] `is the LATCH system so fragile that if the child was 38 pounds instead of 37 it might not hold in a crash?' ”
Consumers Union sent a letter stating that it was “worried that the new rules may encourage parents to secure heavier child seats using standard safety belts instead of the LATCH system.” Consumers Union states that “each CRS will still feature a different maximum recommended child weight limit, based on the differences between the seat's weight and the 65 lb limit of the lower LATCH anchors,” which, the letter writer believes, will confuse caregivers.
sent a letter expressing its belief that the 65-lb combined weight threshold was “far too conservative a limitation given the dynamic capacity of the lower anchors in vehicles” and asks that NHTSA “allow a maximum weight of CRS plus occupant to be limited to 80 lbs with the use of lower anchors.” These are the same arguments that Diono made in response to the NPRM when the company was named Sunshine Kids. Diono believes that there is “much data from testing analysis that has shown lower anchors support total masses larger than the proposed limit of 30.5 kg,” and states that it has data from its sled testing which “show that with a combined mass of 78 lbs to ~110 lbs the lower anchors see dynamic loads well within the dynamic capacity of the lower anchors.” Diono also states that “ECE-R44 has recommended the combined weight limit be 33 kgs (Combined mass of CRS plus occupant) or 72.6 lbs.”
The Alliance submitted correspondence focused on the need for the label to address rear-facing child restraints equipped with an internal harness that are sold for heavier children, which are used without a tether. The Alliance highlights that it reviewed “some of the heavier 3-in-1 child restraints currently on the market, especially those which have been certified for use up to 40/45 lbs rearward-facing,” and notes that “a potential weight combination of up [sic] 73.8 lbs becomes apparent—without use of a tether.” The Alliance seeks “to ensure that the label is also applied to rear-facing child restraints.”
b. Other Issues
NHTSA also received correspondence from Graco asking that harness-equipped CRSs recommended for children up to 70 lb in weight should be excluded from the head excursion requirements if the CRS height restrictions do not accommodate the HIII-10C dummy.
Graco also raises a question about S5(f) of the final rule, which applies to harness-equipped CRSs. S5(f) refers to the weight of the test dummy used to test the CRS. Graco suggests that NHTSA publish a list of the weights for each test dummy to make it “easy for manufacturers to determine which [anthropomorphic test device] and CRS combinations need to be tested with each type of belt and provide more standardized results for consumers.”
IV. Agency Response
NHTSA has evaluated all relevant issues presented above and has made the following decisions in responding to those issues.
a. The Label
A Label Is Necessary To Address a Safety Need
NHTSA has determined that the information presented by the label in question is necessary to address a safety need. The information reduces the likelihood that consumers will use the child restraint anchorage system with a combined weight of child plus CRS weight too high for the anchorages in a crash. FMVSS No. 225 requires the anchorage system to withstand crash forces resulting from a combined (child+CRS) mass of 65 lb.
Not having information about the weight limits poses an unreasonable risk of overloading the child restraint anchorage system given that CRS weights are increasing (currently there is no limit on the size and mass of CRSs), harness-equipped CRSs are being produced that are marketed for children of heavier masses than 40 lb, and peak vehicle accelerations are much higher now (some exceed 60 g) than the 48 g the agency had assumed in 1999 when designing the strength requirements of FMVSS No. 225. We believe that information about child weight limits needs to be provided on the CRS, given the design limits of child restraint anchorage systems and the changing physical demands on the system from modern child restraint and vehicle designs.
In an April 11, 2011 letter to NHTSA, the Alliance and Global Automakers expressed support for a label such as that adopted by the 2012 rule. These Start Printed Page 10399vehicle manufacturer groups expressed concern “that there appears to be a trend toward increased weight of child restraints. This trend, if it continues, could call into question the validity of the 48 pound estimate for appropriate maximum child weight capacity.” NHTSA agrees that this development is a cause for concern, and believes that the labeling requirement addresses this potential safety problem.
The market has not provided the information consumers need. Vehicle and CRS users' manuals have conflicting or a lack of information on the maximum child weight limit for lower anchor use. Most vehicle manufacturers do not include a child weight limit for lower anchor use in their vehicle owner's manual. A 2011 manual developed by SRN, “LATCH Manual,”
indicates that only about 54 percent of vehicle “makes” provides information on the weight limits of child restraint anchorage systems.
Child restraint manufacturers' recommendations for using the child restraint anchorage system are also varied and generally unhelpful. NHTSA reviewed approximately 40 CRS manuals from different CRS manufacturers to see the current recommendations of CRS manufacturers. In our sample, Dorel and Evenflo did not specify a maximum child weight for use with the child restraint anchorage system. Graco and Recaro specified using the vehicle manufacturer's weight limits for use of the child restraint anchorage system and also specified a maximum child weight of 48 lb for use of the anchorages. Britax recommended that consumers follow vehicle manufacturers' instructions and that, if a vehicle manufacturer does not provide a limit, consumers should assume a 40 lb maximum child weight limit for lower anchors. Diono recommended use of the child restraint anchorage system for children weighing up to 65 lb (corresponding to the weight of a 50th percentile 9.5 year-old) and even, for some models, 80 lb (corresponding to the weight of a 50th percentile 11 year-old).
Since most vehicles do not specify a child weight limit for lower anchor use, and since CRS instruction manuals generally have no information (e.g., Dorel and Evenflo), refer to the vehicle owner's manual (Graco, Britax, Recaro), or have conflicting information on the child weight limit for using the lower anchorages (Graco, Recaro), many consumers are unaware or unsure as to the weight limits of child restraint anchorage systems. A consumer looking in the CRS manual might be referred to a non-existent vehicle owner's manual instruction on child weight limits for lower anchor use, or might be informed that the anchorage system may be used to a weight beyond the intended design limit of many if not most vehicles' anchorage systems.
This problematic situation can be fixed if the CRS has the required information about the weight limits. With the information, consumers will have convenient access to facts about the child weight limit for lower anchor use. A label with the information will provide clear and consistent information for determining the child weight limit for lower anchor use, which will be easily accessible to the caregiver at all times.
Consumers following this information will virtually eliminate the risk of anchorage failure in a crash.
We do not believe that specifying a combined (child+CRS) weight limit in the vehicle owners' manual rather than on a CRS label would be as effective at communicating the information as placing a label on the CRS. First, the consumer will need to determine the weight of the CRS and then calculate the maximum child weight limit. We believe that these additional actions required by the consumer are unreasonable; the consumer is unlikely to take the step of assessing the CRS weight or may not bother to make the calculation. Second, a recent survey 
conducted by the agency showed that only 14 percent of caregivers use the vehicle owners' manuals for information about installing CRSs. This indicates that most consumers will not learn of the instruction by way of the vehicle owner's manual.
We disagree with JPMA's and Diono's assertion that the label will result in lack of confidence in child restraint anchorage systems. We believe that the label will provide clear and consistent information on the use of child restraint anchorage systems and will thereby promote more trust in child restraint anchorage systems. More importantly, the information will virtually eliminate the risk of a failure of an anchorage system in attaching a CRS to the vehicle.
Such failures, not the label, would reduce consumer confidence in child restraint anchorage systems. We are taking action now to instruct consumers of the intended use of the anchorage system to avoid failures in the field.
The Strength Was Based on a 65-lb Combined Weight Limit
The petitioners state that they wish to “preserve the extended use of lower anchors.” They state that the preamble for the final rule establishing FMVSS No. 225 refers to a child weight of 65 lb, and that the intent of the agency in establishing the standard was “for anchors to be strong enough to accommodate CRs [sic] that would in themselves weigh at least 15, possibly 20 pounds, which implies a combined weight of at least 80 to 85 lbs.”
Agency Response: The petitioners' view is incorrect. The preambles 
analyzing, explaining, and developing the rationale for FMVSS No. 225's strength requirement overwhelmingly refer to a combined weight (child+CRS) of 65 lb. The entire engineering analysis upon which the strength requirement Start Printed Page 10400was based uses a combined weight of 65 lb.
To illustrate, NHTSA explained the basis for FMVSS No. 225's 15 kN strength requirement in a 2003 document responding to petitions for reconsideration of various aspects of the 1999 final rule. NHTSA stated that the agency based the strength requirement—
on an analysis of the forces that are likely to be imposed on a LATCH system in a crash. NHTSA agrees [with a petitioner] that the maximum expected force acting on the center of gravity of a child in a child restraint is calculated as the total mass of the child and the child restraint system (“the child/CRS system”) multiplied by the acceleration of the system. . . . Assuming a child and child restraint mass of 29.7 kg (65 lb), the dynamic force expected to act through the center of gravity of the child/CRS system in a 48.4 g crash is approximately 14,100 N. [Emphasis added.] 68 FR 38208, 39218-38219, June 27, 2003.
References to a “child” weight of 65 lb rather than to a “combined” weight in the 2010 SNPRM were in error, as the Alliance, JPMA and others have pointed out. Such references were imprecise and limited in describing the assumptions underlying the strength requirement of child restraint anchorage systems. The Alliance explained that the load calculations for the 15 kN strength requirement were based on a combined maximum (child+CRS) weight of 65 lb.
The Alliance and others were concerned that the proposed wording that referred to a 65-lb child weight did not adequately account for the weight of the CRS and thus would be providing misinformation. NHTSA agreed with the commenters and made the correction in the final rule.
The present petitioners state that “What is proposed [sic] in the final rule, is, in effect, a major change of interpretation of anchor weight limits without any opportunity for assessment and comment that is usual in regulatory changes.”
This assertion is without merit. As explained above, the agency did not make a “change of interpretation of anchor weight limits” by basing the final rule on a combined child+CRS weight of 65 lb. A 65 lb combined weight limit was the established engineering basis for the strength requirement of FMVSS No. 225 from the beginning of the standard. The 2010 SNPRM was in error in referring to a child weight alone of 65 lb. The 2012 final rule remedied the error by referencing combined weight (child+CRS).
Moreover, the weight to which the label refers was an issue well within the scope of the present rulemaking. The question of the weight limits of child restraint anchorage systems and the safe use of the anchorage system with heavier children were crucial aspects of the 2010 SNPRM (see section VII.a. of the SNPRM, 75 FR at 71659). Upon proposing a label to inform consumers of the limits of the child restraint anchorage system, the SNPRM specifically asked for comment on the child weight variable: “Comments are requested on the label's reference to the 65 lb (29.5 kg) threshold.” 75 FR at 71659.
In addition, vehicle manufacturer groups (Alliance and Global Automakers) and JPMA commented on the SNPRM, informing NHTSA that the proposed wording that referred to a 65-lb child weight alone did not adequately account for the weight of the CRS and was thus providing incorrect information. NHTSA benefited from the comments and corrected the weight limit to reflect the weight of the child+CRS, as designed by FMVSS No. 225, in the final rule. The agency was not required to reissue another proposal for notice and comment to make this correction.
Diono believes that there is “much data from testing analysis that has shown lower anchors support total masses larger than the proposed limit of 30.5 kg” and states that it has data from its sled testing which “show that with a combined mass of 78 lbs to ~ 110 lbs the lower anchors see dynamic loads well within the dynamic capacity of the lower anchors.” Diono believes that its tests show that, with a combined child and child restraint weight of 80 lb, the dynamic loads on the anchors are in the range of 9 kN at each lower anchor. Diono also states that NHTSA has tested CRSs (some weighing 30 lb) for many years using the Hybrid III 6-year-old (HIII-6C) dummy weighing 48 lb (for a combined weight of 78 lb) as part of its compliance program with no anchorage failures. Based on this information, Diono concludes that there is a very safe margin with the use of lower anchorages for a combined child and CRS weight of 80 lb.
The agency disagrees that Diono's test data indicate that NHTSA should amend the labeling requirement in such a way that condones the use of the lower anchorages with a combined child and CRS weight of 80 lb. Diono's testing consisted of sled tests using the FMVSS No. 213 test bench and a sled pulse (47 G pulse and a 35 mph velocity) representing the crash pulse of a 2001 Toyota Echo in an NCAP frontal crash test. The docket submissions from Diono show that for sled tests performed with the 47 G pulse and combined child and CRS weight of 82 lb (65 lb dummy + estimated 17 lb CRS) and 97 lb (80 lb dummy + estimated 17 lb CRS), the peak total load on the child restraint anchorages were 25.7-27.3 kN. Those loads clearly exceed the 15 kN quasi-static load minimum strength requirement of the anchorage system per FMVSS No. 225.
Furthermore, while the Toyota Echo pulse at 48 G in an NCAP test was considered a severe pulse in early 2000s, current NCAP data shows that many recent vehicle models have stiffer front ends than the Echo, with peak accelerations in excess of 50 G.
Additionally, Diono's data are inadequate because the data were obtained from sled tests conducted with an FMVSS No. 213 test bench seat. The child restraint anchorage system bars on the bench seat are designed and constructed to withstand repeated loading in 30-35 mph sled tests, i.e., they are reinforced over and above the anchorages of actual vehicles. Diono did not provide any actual vehicle test data (static or dynamic). The strength of child restraint anchorage systems in vehicles is evaluated according to specifications in FMVSS No. 225, which include a quasi-static load test of 15 kN applied to the lower anchors and tethers and a quasi-static load test of 11 kN applied only to the lower anchors. The lack of anchorage failures on NHTSA's test bench does not indicate that real-world vehicles' anchorages are strong enough to hold the force generated by higher weight children.
Diono referred to Economic Commission for Europe Regulation No. 44 (ECE R.44), “Restraining Devices for Child Occupants of Power-Driven Vehicles,” and ECE R.14, “Safety Belt Anchorages, ISOFIX Anchorages, and Top Tether Anchorages,” stating that these regulations limit to 72.6 lb the combined weight of child and child restraint for ISOFIX use, even though ECE R.14 has slightly less stringent requirements on the ISOFIX anchors than FMVSS No. 225.
NHTSA does not find this view persuasive. For one thing, ECE R.44 limits the maximum child weight for CRSs with harnesses and CRSs equipped with ISOFIX to 40 lb, and specifies that the CRS weight be less than or equal to 33 lb. FMVSS No. 213 does not have such limitations on CRS design at this time. Thus, the overall risk of overloading the anchors in Europe is inherently lower than in the Start Printed Page 10401U.S. In this country, a label is needed to limit the weight on the anchorages to within design parameters.
Second, no showing has been made by Diono that the ECE requirements are sufficient to meet the safety need in the U.S. that is met by FMVSS No. 225. In a 2010 Transportation Research Laboratory (TRL) contract report, Hynd et al.
noted that there is evidence that the current ECE R.14 anchorage strength test requirements may be inadequate for some dummy and CRS combinations allowed in ECE R.44. We are not convinced that FMVSS No. 225's requirements should be made similar to those of ECE R.14.
Diono also states that the 2012 final rule's labeling requirement on lower anchor use contradicts Transport Canada's recent update of Canadian Motor Vehicle Safety Standard (CMVSS) No. 213, “Child restraint systems,” which permits the use of lower anchors to install child restraints with harnesses for children weighing up to 65 lb.
We do not agree. Transport Canada has yet to consider the recent updates to FMVSS No. 213 incorporating the 10-year-old dummy for testing child restraints. We expect Canada to have similar issues as the U.S. regarding child restraint misuse, incorrect installations, and consumer confusion as to the child restraint anchorage systems. Transport Canada may be considering the merits of the label in the future.
The petitioners request that NHTSA “provide any test or field data suggesting the need for a reinterpretation of the original statement that FMVSS 225 was devised for a child weighing 65 to 80 . . . lbs.” As explained above, FMVSS No. 225 was developed to ensure that crash forces generated by a 65 lb combined weight will be withstood; it did not presume a child weight alone of 65 to 80 lb. The label is intended to inform consumers about the design limits of child restraint anchorage systems and to keep use of the lower anchorages to within the anchorage system's design limits. The engineering analyses underlying the FMVSS No. 225 strength requirement have been fully discussed. The agency is not obligated to provide “test or field data” to justify why we disagree with the petitioners' view that the weight limit should be based on a child weight alone of 65 to 80 lb.
Nonetheless, there are empirical data on this issue. There has been failure of a child restraint anchorage system in testing conducted by Transport Canada (30-35 mph) involving full frontal rigid barrier crash tests of model year (MY) 2009 and 2010 vehicles. Transport Canada placed child restraints in the outboard rear seating positions using the child restraint anchorage system (including the top tether).
The program involved 28 crash tests with the HIII-6C dummy and 4 crash tests with the HIII-10C dummy. The weight of the CRSs used in the tests ranged from 11.4 lb to 25.11 lb. The peak vehicle acceleration in these crash tests ranged from 30 g to 68 g. The total anchorage loads (sum of forces on the lower anchors and the tether anchor) ranged from 7.5 kN to 20.8 kN with the HIII-6C dummy, and from 13.3 kN to 20.4 kN with the HIII-10C dummy (see Tables A1(a) and A1(b) in the Appendix to this preamble).
The failure occurred in a 35 mph frontal crash test of a 2010 Kia Forte with the HIII-10C dummy restrained in Safety 1st Apex 65 child restraint. The CRS was installed in the right outboard rear seat with lower and top tether anchorages. The CRS weighed about 13 lb. The combined weight (child+CRS) in this test was 90 lb, the peak vehicle acceleration was 46 G. The total maximum anchorage loads measured in this test was 20,395 N. During the test, the inboard anchor, which was held in place by two bolts, pulled through the sheet metal resulting in a failure at the attachment point. The anchorage failure demonstrates a finite limit to the strength of the child restraint anchorages.
We are concerned that there are factors in play that have developed in recent years that raise the possibility that the limits of the child restraint anchorage system will be surpassed in more and more vehicles by the ordinary use of modern day CRSs in modern vehicles if measures are not in place to prevent this from happening. CRSs with internal harnesses are being produced that are recommended for children weighing 65 lb or more. The average weight of CRSs was 15 lb when FMVSS No. 225 was first issued; now CRSs are marketed that weigh more than 30 lb. Further, the strength requirements of the child restraint anchorage system were based on a 48 g vehicle acceleration, which is a level being surpassed among current vehicle models in a 35 mph frontal crash. In contrast, there are vehicle models in the current fleet that have peak vehicle acceleration in excess of 50 g in a 35 mph frontal crash.
Also presented in the Appendix in Tables A1(a) and A1(b) are the results of NHTSA's computed maximum total inertial loads on the child restraint anchorage system (F) using the combined weight of the child dummy and the CRS (m) and the peak vehicle acceleration (a),
using Newton's second law of motion (F=ma).
A comparison of the measured and computed total anchorage loads indicates that in 13 of 32 tests (41 percent), the computed anchorage loads were within 10 percent of the measured anchorage loads. In an additional 13 tests (40 percent), computed anchorage loads were within 20 percent of the measured loads. The general similarity between the measured and computed values provides a source of confidence in the anchorage strength requirements in FMVSS No. 225, which was based on a similar inertial load computation using a combined CRS+child weight of 65 lb and a peak acceleration of 48 G.
Almost all of the tests showed the integrity of present day child restraint anchorage systems in vehicles. The relatively low rate of anchorage failures in the Transport Canada vehicle crash tests may be because many vehicle manufacturers are designing the child restraint anchorage systems to be stronger than that required by FMVSS No. 225; the anchorage loads from the combined CRS+dummy weight and the peak vehicle acceleration were within the strength capabilities of vehicle anchorages.
Diono suggests a combined child+CRS weight limit of 80 lb. We believe that this suggestion raises an unreasonable risk that the lower anchorages would be overloaded, resulting in anchorage failure. The computed total child restraint anchorage load for a peak Start Printed Page 10402vehicle acceleration of 65 g and a combined child+CRS weight of 80 lb is 23,187 N, which is significantly higher than the measured total anchorage loads in the Transport Canada test series. Since there are vehicle models with peak vehicle accelerations of approximately 60-70 g,
having total anchorage loads exceeding 23,000 N is a distinct possibility if the combined weight limit is increased to 80 lb as suggested. Thus, we decline the request.
Another matter of concern to us is the low usage rate of the tether anchor and how nonuse of the tether, among other things, results in higher loads being imposed on the lower anchorages. Our survey data 
indicates that approximately 30 percent of forward-facing child restraints that are installed using the lower anchorages do not have the tether attached. To study this and other issues, NHTSA performed sled tests at the agency's Vehicle Research and Test Center (VRTC) to measure the loads experienced by child restraint anchorages in a simulated crash. VRTC conducted 24 sled tests using the weighted 6-year-old Hybrid III dummy and three child seat models (Safety 1st Apex 65, Sunshine Kids Radian 65 and Britax Frontier 85) in two vehicle bucks (2010 Kia Forte and 2010 Ford Focus).
The child restraint models were selected because these models are marketed for heavier/older children, and because these CRSs were tested in the vehicle crash tests at Transport Canada. The two vehicle bucks were selected because both the Kia Forte and the Ford Focus had high measured anchorage loads in the Transport Canada frontal vehicle crash test program.
The agency selected two 35 mph, 35 g and 100 millisecond (ms) pulses to simulate a frontal crash. One of the pulses was front loaded while the second one was rear loaded (see Figure 1).
These two acceleration pulses were selected to cover the different vehicle acceleration pulse shapes observed in 35 mph full frontal rigid barrier crash tests.
The agency specifically selected the Kia Forte because of the lower anchorage failure observed in the vehicle crash test conducted by Transport Canada (discussed in the previous section). Transport Canada's tests used the Safety 1st Apex 65 CRS (approximately 13 lb) and the HIII-10C dummy (77 lb), for a combined weight of about 90 lb. VRTC's test used the same Safety 1st CRS model and a weighted HIII-6C dummy (66 lb), for a combined weight of approximately 79 lb.
VRTC conducted a sled test with the Kia Forte buck and a front loaded sled pulse (shown in Figure 1), with the CRS installed in the right rear outboard seating position using the lower anchors and the top tether. Post-test evaluation showed some deformation of the sheet metal with some forward pull of the lower anchorages but not a complete failure of the anchorages. The total anchorage loads (lower anchors+tether) was measured to be 17,330 N and the total load on the lower anchors (inboard+outboard) was 11,666 N (See Table A2 in the Appendix). However, VRTC later conducted another test, identical to the first except the tether was not attached. In that test, there was complete failure of the lower anchor Start Printed Page 10403hardware. The entire bolt and nut assembly pulled through the sheet metal. The total measured force on the lower anchors in this test was 14,922 N, which is 30 percent higher than the total lower anchor load in the earlier test with the tether attached.
NHTSA has reviewed all the sled tests conducted at VRTC (three child restraints in two vehicle bucks) and has determined that the ratio of lower anchor loads (when the tether is not attached) to lower anchor loads (when the tether is attached) ranges from 1.3 to 1.6. That is, these sled test results indicate that the loads on the lower anchorages are 30-60 percent higher when the tether is not used to install the CRS than when the full child restraint anchorage system (lower anchors+tether anchor) are used to install the CRS.
Thus, in further answer to Diono and others as to why we disagree with the suggested approach to increase weights to 80 lb, there is evidence of lower anchor failure when the tether was not attached at a combined weight of only 78 lb. Since we have evidence that 30 percent of forward-facing child restraints installed using the lower anchorages do not have the tether attached in the real world,
the labeling requirement reduces the possibility of field failure of lower anchorages, such as that observed in the sled test with the Kia Forte buck, when the combined (child and child restraint) weight approaches 80 lb.
Amendments To Revise the Labeling Requirement 
The petitioners would like to “preserve the extended use of lower anchors.” Ms. Baer said in correspondence to NHTSA that “ugly numbers—like 37 or 41 [lb]—are scary to parents & technicians,” and “will likely erode confidence in the LATCH system.” Consumers Union stated its belief that it will confuse caregivers when “each CRS will still feature a different maximum recommended child weight limit, based on the differences between the seat's weight and the 65 lb limit of the lower LATCH anchors.”
Agency Response: NHTSA has evaluated the petition and the related correspondence and has decided to partially grant the petition. NHTSA is making two primary changes to the labeling requirement.
First, we agree with the view that the wording of the label specified in the 2012 final rule could lead consumers to misunderstand the instruction, remove the harness from the CRS before they should, or otherwise not follow the instruction. NHTSA is thus amending S5.5.2(g)(1)(ii) of the 2012 final rule to remove the instruction from that section. Instead, the instruction will be placed on a diagram that FMVSS No. 213 presently requires to be on CRSs under S5.5.2(l) of the standard. S5.5.2(l)(3) requires CRSs to be labeled with an installation diagram showing the CRS installed in a seating position equipped with a child restraint anchorage system (S5.5.2(l)(3)). We are adding a provision to S5.5.2(l)(3) to specify that a statement about child weight be included with the diagram.
The statement consists of a phrase, “Do not install by this method for a child weighing more than * lb.” The “*” value is the difference between 65 lb and the CRS weight, as discussed in the 2012 final rule. Alternatively, as discussed in the next section, the “*” value may be rounded up, subject to certain conditions.
An example of the installation diagram with the information for the child weight limit for lower anchor use and for promoting tether use is shown below in Figure 2.
The advantage of using the diagram is that it separates the child weight limit for lower anchor use from all the other information on the label in S5.5.2(g)(1)(ii) and puts it in a location where relevant installation information is provided. It is also advantageous to use diagrams over words to communicate information. The instruction on weight limits is concise and clear. This change will add more clarity regarding the child weight limits and will also be easily available to the caregiver installing the CRS.
Second, NHTSA concurs that the uniquely specific weight values provided on each CRS, based on the difference between 65 lb and the actual weight of the CRS, could be confusing to some consumers. For this reason, the agency is amending the final rule to add some flexibility in the maximum child weight calculation so that the label could be rounded up to display a child weight that is a multiple of five lb, which will be easier for consumers to remember, possibly less confusing to them, and appropriate from a safety point of view. This “rounding up” of Start Printed Page 10404the value is at the option of the manufacturer.
To provide this flexibility, the agency balanced the merits of allowing the child weight limit to be rounded up with the need to avoid an unreasonable risk of potentially overloading the anchorages. We also recognized the need to give different accommodation for CRSs in the forward-facing and rearward-facing modes.
CRSs in the Forward-Facing Mode 
NHTSA is amending the February 27, 2012 final rule to permit CRS manufacturers some flexibility in the calculated child weight limit for use with child restraint anchorage systems. We are retaining the requirement that the CRS must specify a maximum child weight for lower anchor use unique to each CRS model. Under the 2012 final rule, the maximum child weight that must be specified on the label is less than or equal to the difference between 65 lb and the weight of the CRS in pounds. Under today's final rule, that requirement is retained, but we are also providing manufacturers an option of rounding the value up to the next multiple of 5 lb. We are adding a provision in FMVSS No. 213 that specifies a lookup table for the maximum child weight limit in multiples of 5 lb for different weight ranges (65 − CRS weight (lb)) and are providing manufacturers the option of employing the table to round up the child weights. See Table 1, below.
Table 1—For CRSs in Forward-Facing Mode
|x = 65 minus CRS Weight (lb)||Child weight limit on label (lb)|
|20 < x ≤ 25||25|
|25 < x ≤ 30||30|
|30 < x ≤ 35||35|
|35 < x ≤ 40||40|
|40 < x ≤ 45||45|
|45 < x ≤ 50||50|
|50 < x ≤ 55||55|
|55 < x ≤ 60||60|
We recognize that there is a possibility that this amendment will permit a manufacturer to indicate a child weight limit on the label that, when combined with the CRS weight, the combined (child+CRS weight limit) could marginally exceed 65 lb. For instance, if the CRS weighed 19 lb, then x = 65 lb minus 19 lb = 46 lb; rounding up results in a child weight limit on the label) = 50 lb. This would lead to a combined (CRS + child) weight = 50 lb + 19 lb = 69 lb. Although this combined weight is greater to a slight degree than 65 lb, we believe this situation is acceptable for the following reasons.
First, data indicate that vehicles are equipped with child restraint anchorage systems (lower anchorages plus tether anchorage) that sufficiently surpass the minimum strength requirement of FMVSS No. 225 such that the anchorages will withstand crash forces generated by a combined (child+CRS) weight of 70 lb. NHTSA performed quasi-static tests on the child restraint anchorages in eleven MY 2006-2011 
vehicle models and 18 MY 2013 vehicle models 
to explore the strength of the anchorages in the current fleet. (These vehicles were previously crash-tested, but NHTSA examined the vehicles to assess the condition of the child restraint anchorage systems to determine the suitability of the vehicles for inclusion in the quasi-static test program.) The tests consisted of pulling the lower anchorages alone at the two outboard rear seating positions using the Static Force Application Device 2 (SFAD 2) 
as specified in FMVSS No. 225, using the same loading rate but to higher loads or to anchorage failure. A static pull test was also conducted on the tether anchors alone in three rear seating positions using a cable at loading rates similar to that specified in FMVSS No. 225, but again to higher loads or to anchorage failure.
Among the 11 MY 2006-2011 vehicle models tested, 19 lower anchor sets (comprising two lower anchor bars) and 27 tether anchors were subjected to quasi-static loads. Of these, 14 lower anchor sets had strengths greater or equal to 20 kN, and all the tether anchors had strengths greater than 10 kN. Among the 18 MY 2013 vehicle models tested, 37 lower anchor sets and 46 tether anchors were subjected to quasi-static loads, among which 24 lower anchor sets had strengths greater than 20 kN and 25 tether anchors had strengths greater than 10 kN.
The test results are set forth in a technical document placed in the docket. All in all, the results indicate that the quasi-static lower anchorage strength in current vehicles is significantly higher that required by FMVSS No. 225. The lowest force that produced lower anchor failure was 19.7 kN (2010 Kia Forte).
Our testing suggests that child restraint anchorage systems as currently manufactured are capable of withstanding the forces from a combined weight of 70 lb in a crash.
Second, although there is no consistent and direct correlation between dynamic to static strength of anchorage systems and the dynamic to static strength ratio is vehicle specific, data show that child restraint anchorage systems are able to withstand higher loads dynamically than statically. Our test data demonstrate that the dynamic strength of the child restraint anchorage systems (lower anchors+tether anchor) in our tests was greater than the 15 kN load required by FMVSS No. 225. In the Alliance's petition for reconsideration of the strength requirements of the 1999 final rule, the Alliance indicated that the quasi-static test load of FMVSS No. 225 simulating a high-speed impact should be approximately 50 percent of the expected dynamic load.
As discussed in the 2003 final rule responding to petitions for reconsiderations (68 FR 38218), Toyota determined that the tether anchorage was able to withstand about 30 percent greater loads dynamically than statically. NHTSA has considered these findings and believes that data indicate that the child restraint anchorage system will be able to withstand the crash Start Printed Page 10405forces generated by the combined child weight (rounded up) + CRS weight.
CRSs in the Rear-Facing Mode 
Rear-facing CRSs typically do not have a top tether attachment. When FMVSS No. 225 became effective in 1999, rear-facing child restraints were generally recommended for children weighing up to 20 lb. Currently in the market, there are “3-in-1” child restraints that alone weigh more than 20 lb that are recommended to use rear-facing with children weighing up to 45 lb. Thus, for these CRSs, the combined weight of CRS and the maximum weight of child recommended for the CRS exceeds 65 lb. Since these rear-facing child restraints are only attached using the lower anchorages without a tether, the lower anchorages are subjected to greater loads in a crash than if a similar weight child and CRS were in the forward-facing mode with the tether attached.
In its correspondence sent to the agency, the Alliance requested that NHTSA make clear that the label limiting the combined (child+CRS) weight to 65 lb for lower anchor use also must be placed on rear-facing child restraints.
In response, we agree to reiterate that the labeling requirement of the February 2012 final rule applies to those CRSs using lower anchorages in the rear-facing mode. There is good reason for the applicability to these CRSs, as the safety need addressed by the label is relevant to rear-facing CRSs as it is to forward-facing CRSs. However, we believe that the combined child+CRS weight should not exceed 65 lb for CRSs in the rear-facing mode under any circumstances, unlike the potential 70 lb limit for forward-facing restraints using the 3-point anchorage attachment (lower anchors plus tether anchor). This is because FMVSS No. 225 requires the minimum strength of lower anchorages alone to be only 11 kN (compared to the 15 kN strength of the full 3-point anchorage system).
Accordingly, manufacturers of covered rear-facing CRSs must specify a maximum child weight limit for lower anchor use. (Again, the covered CRSs are those that are recommended for use in the rear-facing mode, for which the combined weight of the CRS and the maximum recommended child weight for the rear-facing mode exceeds 65 lb.) We are retaining the provision that each covered CRS must be labeled with the maximum child weight for use with the lower anchors, which is less than or equal to the difference between 65 lb and the weight of the CRS in pounds. The CRS manufacturer is to provide the child weight on the installation diagram specified by S5.5.2(l).
However, under today's final rule, we are also providing manufacturers an alternative of using a maximum child weight value that is a multiple of 5 lb by way of a lookup table. This alternative is adopted to enable manufacturers to avoid displaying an “ugly number” for the child weight. We are adding a provision in FMVSS No. 213 that specifies the lookup table for the maximum child weight limit in multiples of 5 lb for different weight ranges (60 − CRS weight (lb)) and are providing manufacturers the option of employing the table to obtain the maximum child weight limit. The maximum child weight limit is based on a calculation of 60 lb minus the weight of the CRS. We are using 60 lb rather than 65 lb as a starting point to ensure that the rounded value does not exceed 65 lb. This is important because for rear-facing restraints, the top tether will not be employed so the lower anchorages will be experiencing more crash forces than the full child restraint anchorage system. See Table 2, below.
Table 2—for CRSs in Rear-Facing Mode
|x = 60 − CRS weight (lb)||Child weight limit on label (lb)|
|15 < x ≤20||20|
|20 < x ≤25||25|
|25 < x ≤30||30|
|30 < x ≤35||35|
|35 < x ≤40||40|
|40 < x ≤45||45|
|45 < x ≤50||50|
|50 < x ≤55||55|
Based on our testing experience, we believe that a set of minimally compliant lower anchorages (with a quasi-static strength of 11 kN) has sufficient dynamic strength to withstand inertial loads from a combined weight of 65 lb in a 35 mph frontal crash.
CRSs Used Both Rear- and Forward-Facing
For CRSs that have a rear-facing and forward-facing mode with internal harnesses, we prefer that the CRS provide installation diagrams in both modes along with a corresponding maximum child weight limit for lower anchor use, if such a limit is required. However, we are not requiring installation diagrams in both modes at this time. If a CRS manufacturer only provides one installation diagram and if a child weight limit is required in only one of the modes (rear-facing or forward-facing), then the diagram shall depict the installation in that particular mode along with the corresponding child weight limit. Alternatively, if a child weight limit is required in both modes and only one installation diagram is provided, then the child weight limit is either less than or equal to the difference between 65 and the CRS weight (lb) or the lesser of the child weight limits determined by way of Table 1 for the forward-facing mode and Table 2 for the rear-facing mode.
The Label's Effect on Current Weight Recommendations
The petitioners express concern that the 65 lb combined maximum weight limit “will unnecessarily restrict the use of the LATCH system and force caregivers back to using seat belts for anchoring forward-facing” child restraints.
We do not agree that the new label will significantly reduce the number of CRSs that are installed with the lower anchorages of child restraint anchorage systems. Currently, technicians at child seat inspection stations recommend use of the child restraint anchorage system for children weighing between 40-48 lb, which corresponds to about a 6-year-old (see Table 3, below).
We reviewed the weights of harness-equipped CRSs in the market since 2008 
to assess what the child weight limit for lower anchor use would be per the new labeling Start Printed Page 10406requirement. The detailed data are provided in Table A3 in the appendix to this preamble. Our review of 69 forward-facing harness-equipped CRSs showed that only 3 percent (2/69) of CRS models would have a child weight limit less than 40 lb. A child weight of 40 lb corresponds to a 50th percentile 5-year-old child by weight (see Table 3, below). Twenty-nine (29) percent (20/69) would have a child weight limit of 40 or 45 lb. Thirty-six (36) percent (25/69) would have a child weight limit greater or equal to 50 lb for lower anchor use per the new labeling requirement, which corresponds to approximately a 40th percentile 7-year-old child, by weight. Finally, 32 percent (22/69) would not require a label specifying maximum child weight for lower anchor use since the combined CRS and maximum recommended child weight in harness-equipped CRSs is less than 65 lb (17 of these CRSs have a recommended child weight of 40 lb and for the remaining 5 CRSs it is 50 lb). Thus, the label will expand lower anchor use past the 48 lb child weight limit for forty-four (44) percent of child restraints, and only restricts approximately 3 percent of CRS models to a child weight limit less than 40 lb for lower anchor use. Overall, the label will not reduce current lower anchor use but will provide clarity and assurance that the anchors can be used as the child grows, which may in fact increase use of the anchors.
Table 3—5th, 50th, and 95th Percentile Weight and Height of Children by Age (CDC Growth Charts 2000)
|Age||Weight (lb)||Height (in)|
|5th percentile||50th percentile||95th percentile||5th percentile||50 percentile||95 percentile|
The agency found no infant carriers for which the combined CRS+child weight (CRS weight + maximum child weight recommended for infant seat) exceeded 65 lb; therefore, no infant carrier will currently need the label.
Among 46 CRS convertible and 3-in-1 models which can be used in rear-facing mode, only 4 CRS models (8.7 percent) had a combined child+CRS weight (maximum child weight + CRS weight recommended for rear-facing mode) in excess of 65 lb, which requires a label specifying the maximum child weight for lower anchor use (See Table A3 in the Appendix to this preamble). Among these 4 CRSs, one CRS weighs 33.8 lb with a recommended child weight in rear-facing mode of 40 lb, and the remaining 3 CRSs weighed between 22.3-25.8 lb with a recommended child weight in rear-facing mode of 45 lb.
It is unlikely that these CRSs will be used in rear-facing mode to the maximum recommended child weight of 40-45 lb since, as discussed in the next section, the child may get too tall to sit comfortably rear-facing or may exceed the height requirement before the weight limit is reached.
Permitting the calculated child weight limit to be a multiple of 5 lb will result in values that will be easier for the consumer to understand. The agency will incorporate this label in education material so that consumers are aware that there is a maximum child weight limit for lower anchor use and to look for this information on the CRS.
Field data show that harness-equipped CRSs are not now being widely used by consumers for children weighing more than 50 lb. The agency analyzed data from the National Child Restraint Use Special Study (NCRUSS) 
to examine this issue. The survey data show that among children restrained in forward-facing harness-equipped CRSs (for both seat belt and lower anchor installation), 92.3 percent of the children weighed 40 lb or less, 5.9 percent weighed 41 to 50 lb, and only 1.5 percent weighed more than 50 lb (see Figure 3). Data suggest that children are outgrowing CRSs by height rather than by weight.
Start Printed Page 10407
Since rear-facing harness-equipped CRSs are now designed for older/heavier children, the agency also used the NCRUSS survey to explore how these CRSs are used in the field. The NCRUSS survey show that 83.4 percent of children in rear-facing convertible or all-in-one seats (both of which are equipped with harnesses) weighed 25 lb or less, 13.2 percent weighed 26 to 30 lb, 3.2 percent weighed 30 to 35 lb (corresponding to a 50th percentile 4-year-old or 75th percentile 3-year-old), and 0.2 percent weighed more than 35 lb. The NCRUSS survey also show that 85.1 percent of children in rear-facing infant seats weighed 25 lb (corresponding to a 50th percentile 18 month old) or less, 13.9 percent weighed 26 to 30 lb,
and 1 percent weighed more than 30 lb (see Figure 4). The NCRUSS survey show that children weighing more than 35 lb are almost never restrained in rear-facing child restraints.

Using Seat Belts
The petitioners state that “the decision to adopt 65 pounds as the combined maximum weight . . . will unnecessarily restrict the use of the LATCH system and force caregivers back to using seat belts for anchoring forward-facing [CRSs].” JPMA states that CRSs might not achieve a tight fit with a seat belt or may be too difficult to install with a seat belt and that parents might not know to switch to the seat belt during the several-year course of a CRS's use. Dorel states that child restraint anchorage systems are easier to use and have a higher rate of correct installation than seat belts, so an installation by the former is safer than a belt installation.
Agency Response: These arguments are speculative and unsupported. Field data show a high percentage of children weighing over 40 lb restrained in forward-facing CRSs installed with seat belts, i.e., consumers are now attaching CRSs with seat belts at a high rate. The consumers will not be “forced back” to doing something different.
Moreover, recent field data 
shows that most children graduate to booster seats when they reach approximately 40 lb, which corresponds to a 95th percentile 3-year-old or a 50th percentile 5-year-old. Thus, it appears unlikely that the label will “force caregivers back to using seat belts for anchoring forward-facing” CRSs since many children do not now use harness-equipped CRSs when they reach 40 lb in weight.
The arguments that new seat belt designs are incompatible with CRS installation are speculative. Views are evolving regarding the compatibility of new belt designs, such as inflatable seat belts, with CRS installation. For instance, Britax initially recommended against CRS installation using inflatable belts, but has changed its mind and now permits CRS installations with the belts. We do not have reason to believe that seat belts with advanced technologies cannot be designed to install CRSs. We also note that SAE J1819 is undergoing revisions to improve compatibility of seat belts and child restraint anchorages with CRSs.
It would be premature for NHTSA to conclude that changes in seat belt design render installation of CRSs by seat belts unfeasible.
Regarding Dorel's statement, NHTSA believes that the statement is not germane to the issue of the design limits of child restraint anchorage systems. If the anchorages are used in a manner that results in material failure because the design limits of the anchorage system were exceeded, the child passenger is at risk regardless of the relative ease of using child restraint anchorage systems or the tightness of the installation of CRSs on the anchorages.
The petitioners also state that their intent in petitioning for reconsideration of the rule was to “minimize the likelihood that vehicle manufacturers will apply the same formula” to tether anchorages. Issues relating to weight limits for the top tether anchorage are out of scope of this rulemaking.
Increasing the Strength of the Anchorage System
The petitioners believe that NHTSA should require vehicle manufacturers to increase the strength of child restraint anchorage systems to accommodate a higher combined weight. This issue is out of scope of this rulemaking. Start Printed Page 10409
b. Other Issues
Graco requests that the 10YO test dummy only be used to test CRSs when the dummy fits in the seat as per the manufacturer's recommended usage. Graco states that it produces a harness-equipped CRS recommended for a 70 lb child, but limits the recommended seated height of the child occupant and limits the head height relative to the seat. Graco asks that the 10YO dummy not be used to evaluate performance of the CRS if the dummy exceeds the recommended limits on seating height. Graco believes that in the real world, the seat would not be used with a child of this stature, and as a result, the 10YO dummy may give inaccurate readings. Alternatively, Graco suggests that the dummy be used to evaluate CRSs to assess structural integrity, chest resultant, and knee excursion limits but not the head excursion requirement. Graco states that the head excursion measurement resulting from the use of the 10YO dummy would not represent the real world due to the dummy being significantly taller than the recommended child occupant.
The agency is denying Graco's request. It is not in the public interest to exclude testing those CRSs recommended for children of a weight range represented by the 10YO dummy but whose height may be lower than that of the dummy.
The agency indirectly addressed this issue in the rulemaking. In the 2008 SNPRM (73 FR 3908), we had considered whether FMVSS No. 213 should expressly require that each CRS be capable of fitting the test dummy that is specified in S7 of the standard to evaluate the CRS. The agency only received comments from JPMA, which stated that child restraints are designed to accommodate the dummies with which they will be tested and that an explicit “fit” requirement is not required. After reviewing the comment, the agency decided not to pursue a fit requirement, assuming it was not needed because manufacturers already ensure that CRSs accommodate/fit the appropriate child dummies.
Graco is now indicating that a CRS it has produced is recommended for children represented by the 10YO dummy weight-wise, but does not fit the dummy height-wise. We do not believe it would be in the interest of safety to exclude the CRS from testing with the 10YO dummy, or exclude the CRS from a performance requirement, because the CRS does not actually fit the dummy. We believe that a better approach would be to subject the CRS to testing with the dummy if the manufacturer recommends the CRS for use with children represented by the dummy, as designated by S7 of FMVSS No. 213.
We have not been provided with any compelling information to exclude Graco's CRS from testing with the dummy. Graco has the option to lower the child weight recommendation of the CRS in question from 70 lb to 65 lb to avoid testing with the dummy, or it could continue to market the CRS for children over 65 lb and ensure that the CRS meets the FMVSS No. 213 requirements when tested with the 10YO (such as by redesigning the CRS to have a harness slot that can properly accommodate the 10YO dummy and/or making any structural changes needed to ensure integrity and performance using this dummy).
Weights of the Anthropomorphic Test Devices
The February 2012 final rule adopted a provision (S5(f)) that basically excludes CRSs equipped with an internal harness from FMVSS No. 213 while attached to the lower anchors of the child restraint anchorage system under certain circumstances. The circumstances are: The test dummy used to test the CRS is of a weight such that the dummy's weight plus the CRS weight exceeds 65 lb. In a March 29, 2012 letter on this provision, Graco states that:
[T]esting will be required with LATCH if the combined ATD and CRS weight is under the 65 lb limit. Therefore, the weight of the ATD will be important in determining what testing is required for any CRS. Since ATD weights vary and the addition of clothing, shoes, and instrumentation can add significant weight to the ATD, . . . [NHTSA should] publish a list of the useful weight for each ATD to be used for testing.
In response, NHTSA agrees that the provision in the 2012 final rule implies a need for information on the test dummy weights. However, as Graco notes, the test dummy weights vary, and the addition of clothing, shoes, and instrumentation (the weights for which are not specified in NHTSA's regulations) can affect the “weight” of the test dummy and add undue uncertainty to the test provisions of the standard. Uncertainty results from variability in the weight of the dummy due to variances in the clothing, shoes, and instrumentation used with a particular dummy. We conclude that, to avoid this uncertainty, S5(f) should be slightly revised to move from a reference of “a test dummy of a weight” to “the average weight of the child represented by the test dummy.” The average weight of the child represented by the dummy can be specified in FMVSS No. 213—which NHTSA is specifying in this final rule 
—and is not subject to the same degree of variation as the “test dummy of a weight” provision. Thus, we will reword S5(f) to exclude from lower anchor testing CRSs tested with a dummy that results in the combined weight of the CRS and the average weight of child represented by the test dummy (shown in a table in the standard) to exceed 65 pounds in the forward-facing mode and 65 pounds in the rear-facing mode.
Using the average child weight represented by the test dummy eliminates the variability of dummy weights due to differences in instrumentation and clothing. The average child weights are within the weight range for dummy selection specified in S7.1.2 and so would not change the method of testing CRSs. In addition, using the average child weight in the referenced table ensures that the child restraint system is tested using lower anchors with the test dummy closest to the maximum child weight limit on the label for lower anchor use.
An example illustrating this is as follows. If a CRS weighing 19 lb has a label specifying 50 lb as the maximum child weight for lower anchor use, this CRS will be tested using the lower anchors with the Hybrid III 6-year-old dummy. The average weight of the child represented by this test dummy is 45 lb.
V. Rulemaking Analyses and Notices
Executive Order (E.O.) 12866, E.O. 13563 and DOT Regulatory Policies and Procedures
The agency has considered the impact of this regulatory action under E.O. 12866 and E.O. 13563 and the Department of Transportation's (DOT's) regulatory policies and procedures. This rulemaking action was not reviewed by the Office of Management and Budget under E.O. 12866. This rulemaking is also not significant under DOT's regulatory policies and procedures (44 FR 11034, February 26, 1979).
This response to a petition for reconsideration mostly denies the petition. The few changes that are being made are minor, mostly to clarify a labeling requirement and to provide Start Printed Page 10410flexibility to CRS manufacturers regarding the wording of the label. We estimate that today's final rule has no effect on the estimated costs and benefits and other economic impacts of the February 27, 2012 final rule.
Regulatory Flexibility Act
The Regulatory Flexibility Act of 1980, as amended, requires agencies to evaluate the potential effects of their proposed and final rules on small businesses, small organizations and small governmental jurisdictions. I hereby certify that this final rule will not have a significant economic impact on a substantial number of small entities. Small organizations and small governmental units will not be significantly affected since the potential cost impacts associated with this final rule will not significantly affect the price of child restraints.
This final rule denies most of the petition for reconsideration of the February 2012 final rule. To the extent we are amending the original final rule, the amendments are minor, mostly to clarify a labeling requirement, and adequate lead time is provided. The cost of revising the label is minimal.
National Environmental Policy Act
NHTSA has analyzed this rulemaking action for the purposes of the National Environmental Policy Act. The agency has determined that implementation of this action would not have any significant impact on the quality of the human environment.
NHTSA has examined this final rule pursuant to Executive Order 13132 (64 FR 43255, August 10, 1999) and concluded that no additional consultation with States, local governments or their representatives is mandated beyond the rulemaking process. The agency has concluded that the rulemaking would not have sufficient federalism implications to warrant consultation with State and local officials or the preparation of a federalism summary impact statement. The final rule would not have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.”
NHTSA rules can preempt in two ways. First, the National Traffic and Motor Vehicle Safety Act contains an express preemption provision: When a motor vehicle safety standard is in effect under this chapter, a State or a political subdivision of a State may prescribe or continue in effect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter. 49 U.S.C. 30103(b)(1). It is this statutory command by Congress that preempts any non-identical State legislative and administrative law addressing the same aspect of performance.
The express preemption provision described above is subject to a savings clause under which “[c]ompliance with a motor vehicle safety standard prescribed under this chapter does not exempt a person from liability at common law.” 49 U.S.C. 30103(e) Pursuant to this provision, State common law tort causes of action against motor vehicle or equipment manufacturers that might otherwise be preempted by the express preemption provision are generally preserved. However, the Supreme Court has recognized the possibility, in some instances, of implied preemption of such State common law tort causes of action by virtue of NHTSA's rules, even if not expressly preempted. This second way that NHTSA rules can preempt is dependent upon there being an actual conflict between an FMVSS and the higher standard that would effectively be imposed on motor vehicle or equipment manufacturers if someone obtained a State common law tort judgment against the manufacturer, notwithstanding the manufacturer's compliance with the NHTSA standard. Because most NHTSA standards established by an FMVSS are minimum standards, a State common law tort cause of action that seeks to impose a higher standard on motor vehicle or equipment manufacturers will generally not be preempted. However, if and when such a conflict does exist—for example, when the standard at issue is both a minimum and a maximum standard—the State common law tort cause of action is impliedly preempted. See Geier v. American Honda Motor Co., 529 U.S. 861 (2000).
Pursuant to Executive Order 13132 and 12988, NHTSA has considered whether this rule could or should preempt State common law causes of action. The agency's ability to announce its conclusion regarding the preemptive effect of one of its rules reduces the likelihood that preemption will be an issue in any subsequent tort litigation.
To this end, the agency has examined the nature (e.g., the language and structure of the regulatory text) and objectives of this rule and finds that this rule, like many NHTSA rules, prescribes only a minimum safety standard. As such, NHTSA does not intend that this rule preempt state tort law that would effectively impose a higher standard on motor vehicle or equipment manufacturers than that established by this rule. Establishment of a higher standard by means of State tort law would not conflict with the minimum standard announced here. Without any conflict, there could not be any implied preemption of a State common law tort cause of action.
With respect to the review of the promulgation of a new regulation, section 3(b) of Executive Order 12988, “Civil Justice Reform” (61 FR 4729, February 7, 1996) requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) Clearly specifies the preemptive effect; (2) clearly specifies the effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct, while promoting simplification and burden reduction; (4) clearly specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. This document is consistent with that requirement.
Pursuant to this Order, NHTSA notes as follows. The preemptive effect of this rule is discussed above. NHTSA notes further that there is no requirement that individuals submit a petition for reconsideration or pursue other administrative proceeding before they may file suit in court.
Paperwork Reduction Act
NHTSA has provided a 60-day comment period (77 FR at 11645) and a 30-day comment period (78 FR at 77554) on the collection of information requirement in the previous final rule.
The agency asked for public comments on a collection of information titled, “Consolidated Child Restraint System Registration, Labeling and Defect Notifications.” OMB Control Number: 2127-0576. The requested expiration date of approval is 3 years from the approval date. We requested approval of a revision to a currently approved collection, and for revising an existing label and adding a sentence to the printed instructions of certain child restraint systems (CRSs with internal harnesses for which the combined Start Printed Page 10411weight of the CRS and the maximum recommended child weight for use with internal harness exceeds 65 lb). The added sentences will inform the consumer that the lower anchors of a child restraint anchorage system may be used up to a combined weight of child and harnessed-child restraint of 65 lb. The purpose of this label is to reduce consumer confusion about using the lower anchors and to reduce the risk that the lower anchors will be used in a way that is beyond the design limitations of the anchorage system.
National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272) directs NHTSA to use voluntary consensus standards in its regulatory activities unless doing so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies, such as the Society of Automotive Engineers (SAE). The NTTAA directs the agency to provide Congress, through the OMB, explanations when we decide not to use available and applicable voluntary consensus standards.
NHTSA has reviewed available information and has determined that there are no voluntary consensus standards relevant to this rulemaking.
Unfunded Mandates Reform Act
Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) requires Federal agencies to prepare a written assessment of the costs, benefits, and other effects of proposed or final rules that include a Federal mandate likely to result in the expenditure by State, local or tribal governments, in the aggregate, or by the private sector, of more than $100 million in any one year (adjusted for inflation with base year of 1995). This final rule would not result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector of more than $100 million annually.
Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any rule that: (1) Is determined to be “economically significant” as defined under E.O. 12866, and (2) concerns an environmental, health, or safety risk that NHTSA has reason to believe may have a disproportionate effect on children. This rulemaking is not subject to the Executive Order because it is not economically significant as defined in E.O. 12866.
Executive Order 13211 (66 FR 28355, May 18, 2001) applies to any rulemaking that: (1) Is determined to be economically significant as defined under E.O. 12866, and is likely to have a significantly adverse effect on the supply of, distribution of, or use of energy; or (2) that is designated by the Administrator of the Office of Information and Regulatory Affairs as a significant energy action. This rulemaking is not subject to E.O. 13211.
The Plain Language Writing Act of 2010 (P. L. 111-274) and Executive Order 12866 require each agency to write all rules in plain language. Application of the principles of plain language includes consideration of the following questions:
—Have we organized the material to suit the public's needs?
—Are the requirements in the rule clearly stated?
—Does the rule contain technical language or jargon that is not clear?
—Would a different format (grouping and order of sections, use of headings, paragraphing) make the rule easier to understand?
—Would more (but shorter) sections be better?
—Could we improve clarity by adding tables, lists, or diagrams?
—What else could we do to make this rulemaking easier to understand?
If you have any responses to these questions, please send them to NHTSA at the ADDRESSES section in the heading of this final rule.
