Agency Plans Car Side Window Ejection Rules

     WASHINGTON (CN) – The National Highway Traffic Safety Administration plans to establish a new Federal Motor Vehicle Safety Standard to reduce ejection of vehicle occupants through side windows in crashes, particularly in rollover crashes.




     The agency anticipates that manufacturers would meet the standard by making side impact air bag curtains larger, tethering them, and making them stay inflated longer. The airbags likely also would be made to deploy in both side impact crashes and rollovers, according to an agency proposal.
     Under the standard, the ejection mitigation safety system would be required to prevent a dummy from moving more than a specified distance beyond the plane of a window. The system would have to withstand having the dummy come from “up to” four directions, and at different times after airbag deployment.
