    • 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.
    • 在用于在高速减速的情况下限制车辆乘员的车用安全气囊系统中,用于保持气囊的保持器设置有通气孔,并且用于使气囊充气的充气机最初放置在通气孔的上方。 充气机通过柔性构件附接到保持器或气囊,使得当气囊展开时,充气机从通气孔被提升,从而允许气囊内的气体被排出。 因此,在对车辆乘员进行限制后,不需要设置用于使气囊放气的开口,并且可以有效地使用所产生的气体来使气囊膨胀。 因为通气孔形成在固定保持器中,并且其有效尺寸保持固定,与在气囊本身中形成通气孔的情况相反,可以控制气囊膨胀和放气的时间顺序 高度准确的方式。
