| 04-4277 | Federal Motor Vehicle Safety Standards; Head Impact Protection | Uncategorized Document | This document amends the upper interior impact requirements of the Federal motor vehicle safety standard on occupant protection in interior impact to increase the minimum separation distance between tested areas on vertical surfaces of a motor vehicle. Compliance with the upper interior impact requirements is determined, in part, by measuring the forces experienced by a test device known as the Free Motion Headform (FMH) when it is propelled into certain target circles in the vehicle interior. To ensure that tests conducted within the same vehicle do not affect each other, the standard specifies that tested targets be at least a certain distance apart; currently 150 mm (6 inches). This final rule expands this minimum separation distance for certain target locations through the use of an FMH-shaped "exclusion zone" to alleviate concerns that the striking of one target would affect compliance at other nearby targets in the same vehicle. This final rule also adds targets for pillar-like structures that do not meet the definition of "pillar," i.e., certain door frames and freestanding vertical seat belt mounting structures. | 2004-02-27 | 2004 | 2 | https://www.federalregister.gov/documents/2004/02/27/04-4277/federal-motor-vehicle-safety-standards-head-impact-protection | https://www.govinfo.gov/content/pkg/FR-2004-02-27/pdf/04-4277.pdf | Transportation Department; National Highway Traffic Safety Administration | 492,345 | This document amends the upper interior impact requirements of the Federal motor vehicle safety standard on occupant protection in interior impact to increase the minimum separation distance between tested areas on vertical surfaces of a motor vehicle.... |
