Abstract
An air bag system comprises an air bag having an opening through which gas is supplied. The air bag is folded in a predetermined polygonal shape and is then contained in a pad. An expansion restraining member is provided in the air bag system. The expansion restraining member temporarily holds a peripheral portion of the folded air bag so as to suppress rapid expansion thereof when the air bag is developed. Because the expansion of the peripheral portion is delayed by the expansion restraining member, it is possible to prevent the air bag from developing in the straight thin form toward a passenger. That is, the air bag can be developed in a round shape from its center portion when the gas is supplied into the air bag.
