초록 ▼

A vehicle air bag structure comprises an outer bag which is expansible to a predetermined three dimensional configuration and an expansible inner bag which is located in an internal fluid cavity of the outer bag. The outer bag forms an impact area at a predetermined location when expanded to its predetermined three dimensional configuration. The inner and outer air bags have respective mouth portions which are attached together, and a mouth 46 of the air bag structure 14 is formed at the location of this attachment. The mouth defines a fluid inlet opening, which directs fluid from an external source into the inner bag, and fastening structure which enables the air bag to be fastened to a part of a vehicle air bag assembly. The inner bag is expansible to a predetermined three dimensional configuration, and has a plurality of vent openings for directing fluid from the inner bag into the internal cavity of the outer bag in a direction away from the occupant impact area. The inner bag is formed by a pair of front and rear inner panels and the outer bag is formed by a pair of front and rear outer panels. In forming the air bag, the vent openings are initially provided in the rear inner panel. Then, the rear inner and outer panels are joined together and the mouth of the air bag is formed in the rear inner and outer panels. Finally, the front outer and inner panels are connected to the rear outer and inner panels, respectively, to complete the outer and inner bags.
