{"abstract":"This final rule amends the Federal motor vehicle safety standard (FMVSS) for seat belt assemblies to redefine the requirements and to establish a new test methodology for emergency-locking retractors. Specifically, this final rule establishes a new acceleration-time corridor, adds a figure illustrating the new acceleration-time corridor, provides a tolerance on angle measurements, and adopts the same instrumentation specifications currently found in other FMVSSs containing crash tests.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"National Highway Traffic Safety Administration","name":"National Highway Traffic Safety Administration","id":345,"url":"https://www.federalregister.gov/agencies/national-highway-traffic-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/345","parent_id":492,"slug":"national-highway-traffic-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2005/08/22/05-16524.html","cfr_references":[{"chapter":null,"citation_url":null,"part":571,"title":49}],"citation":"70 FR 48883","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective Date: This final rule is effective October 21, 2005.
