Headliner based supplemental restraint assembly

摘要

A supplemental restraint assembly includes an air bag disposed between a vehicle's roof and the headliner adjacent the side of the vehicle. During deployment of the supplemental restraint assembly, the air bag inflates causing the headliner to extend downward towards an occupant's head and upper torso. The headliner forms a reactionary surface between the occupant and the inflated air bag. An extendable frame assembly disposed between the roof and headliner is preferably employed to positively position the headliner reactionary surface during a side impact or rollover event. The frame assembly maintains the headliner in the extended position after the air bag deflates.
