ABSTRACT:
In a vehicle air bag system for restraining a vehicle occupant under a high deceleration situation, a retainer for retaining the air bag is provided with vent holes, and an inflator for inflating the air bag is initially placed over the vent holes. The inflator is attached to the retainer or to the air bag via a flexible member so that as the air bag is deployed, the inflator is lifted away from the vent holes, thereby allowing the gas inside the air bag to be expelled. Thus, the air bag is not required to be provided with an opening for deflating the air bag after restraining the vehicle occupant, and the produced gas can be efficiently used for inflating the air bag. Because the vent holes are formed in the fixed retainer, and its effective size remains fixed, as opposed to the case of forming a vent hole in the air bag itself, it is possible to control the time sequence of inflating and deflating the air bag in a highly accurate manner.
