Federal Motor Vehicle Safety Standards; Side Impact Protection; Side Impact Phase-In Reporting Requirements

摘要

This NPRM would substantially upgrade the agency's side impact protection standard, especially by requiring protection in crashes with narrow objects and protection against head injuries in side impact crashes with both narrow objects and other vehicles. First, it would upgrade the standard by requiring that all passenger vehicles with a gross vehicle weight rating of 4,536 kilograms (10,000 pounds) or less protect front seat occupants against head, thoracic, abdominal and pelvic injuries in a vehicle-to-pole test simulating a vehicle's crashing sideways into narrow fixed objects like telephone poles and trees. To meet the head injury criteria in the pole test, vehicle manufacturers would likely need to install dynamically deploying side head protection systems, such as head air bags or inflatable air curtains that drop down from the roof line above the door frame. Air curtains can reduce head injuries in side crashes of passenger vehicles with poles and trees as well as side impacts from vehicles with high front ends. They also can help reduce partial and full ejections through side windows. Compliance with the pole test would be determined in two test configurations, one using a
