SUPPLEMENTARY INFORMATION:

Curtain and side air bags are designed to protect occupants in near-side impacts, those to the sides of vehicles adjacent to where Start Printed Page 7740the occupants are seated. Four major types of curtain and/or side air bags have been available in the United States since 1996. However, by model year 2011, 85 percent of new cars and LTVs (light trucks and vans) were equipped with curtains plus torso bags for drivers and right-front passengers. Curtains that deploy in rollover crashes began to appear in 2002; by 2011 about 45 percent of new cars and LTVs were equipped with such curtains.

Logistic regression analyses of FARS data through calendar year 2011 show statistically significant fatality reductions for all four types of curtain and side air bags in near-side impacts for drivers and right-front passengers of cars and LTVs: curtains plus torso bags, 31.3 percent (confidence bounds, 25.0 to 37.1%); combination head/torso bags, 24.8 percent (confidence bounds, 17.7 to 31.2%); curtains only, 16.4 percent (confidence bounds, 3.0 to 28.0%); and torso bags only, 7.8 percent (confidence bounds, 0.4 to 14.7%).

Corresponding analyses of far-side impacts do not show corresponding, large benefits for curtain or side air bags. Curtains that deploy in rollover crashes show a statistically significant effect in first-event rollovers: The estimated fatality reduction is 41.3 percent (confidence bounds, 22.5 to 55.5%). Analyses should be repeated in about 3 or 4 years, when there will be considerably more data available.

In 2007, NHTSA upgraded FMVSS No. 214, “Side impact protection” by adding a crash test of a 20 mph side impact with a pole, at a 75-degree angle (72 FR 51908). The agency anticipated that head-protection air bags such as curtains or combination bags would generally be installed to meet the new requirement. In 2011, NHTSA issued FMVSS No. 226, “Ejection mitigation” (76 FR 3212), anticipating that containment of the occupant would be achieved in many vehicles by curtains designed to deploy in rollovers.

The technical report updates NHTSA's preliminary evaluation of curtain and side air bags, issued in 2007 (72 FR 12857).

Each search yields a simultaneous display of all available information found in FDMS that is relevant to the requested subject or topic.

(3) You may download the comments. However, since the comments are imaged documents, instead of word processing documents, the “pdf” versions of the documents are word searchable.
