Abstract
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.
