The outer bag (50) has a retainer portion (54) defining a central opening (56). The retainer portion (54) has a plurality of fastener openings (58) spaced apart around the central opening (56). An inner bag (60) is located in the inflation fluid volume (59) of the outer bag (50). The inner bag (60) has a retainer portion (110) defining an inflation fluid opening (114) for receiving inflation fluid. The retainer portion (110) has a plurality of fastener openings (79, 89, 99, 109) spaced apart around the inflation fluid opening (114). The inner bag (60) has at least one vent opening (130-136) movable from a closed condition to an open condition, in response to increase in fluid pressure in the inner bag, to enable flow of inflation fluid from the inner bag into the inflation fluid volume (59) of the outer bag (50). The air bag (10) further comprises a plurality of fasteners (32-38) extending through the fastener openings (58) in the retainer portion (54) and through the fastener openings (79, 89, 99, 109) in the retainer portion (110) to secure the inner bag to the outer bag without sewing. The retainer portion (54) is free of stitching openings.Other References
