An inflatable gas bag for restraining systems in vehicles consists of a jacket portion and two side portions sewn thereto. A fold is arranged on the one side portion. The fold is separated from the remaining part of the gas bag by a seam along a separating line extending transversely of the ejection direction. The seam is so dimensioned in its tearing strength that on reaching a predetermined value of the gas bag internal pressure the fold tears. By the fold the expansion direction of the gas bag can be controlled within a relatively wide range. At the same time in desired manner the ejection width and ejection velocity are reduced. Finally, the fold also controls a relief opening which is formed in one of the superimposed wall portions of the fold.

Inflatable gas bag for restraining systems in vehicles

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.
