National Highway Traffic Safety Administration August 22, 2005 – Federal Register Recent Federal Regulation Documents

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.
