Abstract: An inflatable gas bag (10) for vehicle occupant restraining systems comprises only two textile parts (14, 16) shaped to be developed in a plane the edges (18, 20) of which are joined together by a continuous seam (28). Of these textile parts (14, 16) one is generally club-shaped and the other is generally butterfly-shaped.

Abstract: A gas bag assembly in a gas bag restraining system has four elongated bars (2,4,6,8) of identical profile material which each have along their length a first (34) and a second groove (18) with a generally hollow cross-section, and a quadrangular base plate (10) which is provided with openings (14) for receiving at least one gas generator (20) and which has three edges (52,54,56) each engaged in the first groove (34) of one of said elongated bars (2,4,6,8) and a fourth edge (30) secured to another one of said bars. The gas bag (44) has an inlet opening (46) bordered by four tubular sections (42) shaped for accommodation in the second groove (18) of one of said elongated bars. A rod (40) is inserted into each of the tubular sections (42) for retaining the tubular section in the second groove (18) of the respective elongated bar.
