ABSTRACT:
An apparatus (10) for restraining movement of an occupant of a vehicle includes an inflatable air bag (16). When the air bag (16) is inflated to a predetermined pressure, a vent valve assembly (26) opens and vents fluid from the air bag. The vent valve assembly (26) connects the air bag (16) with a support structure. In one embodiment, the vent valve assembly connects the air bag with a door (14) of a vehicle. The vent valve assembly includes a base (46) which extends through an opening (34) in the air bag (16) and through an opening (36) in an inner panel (32) of the vehicle door (14). The base (46) clamps the air bag against the inner panel (32) of the vehicle door (14). The vent valve assembly (26) includes a metal valve element (50) which is plastically deformed by fluid pressure in the air bag (16) to enable fluid to flow from the air bag.
