Abstract

A gas bag restraint system includes a multi-stage inflator and a gas bag in flow connection therewith. The gas bag comprises a first and a second fabric part which are at least approximately congruent, and a fabric strip which is stitched to an edge of the first fabric part and to an edge of the second fabric part. At least one burst seam is provided which in an intact condition forms a fold as a result of which the volume of the gas bag is reduced as compared to a condition in which the burst seam is destroyed. The fold formed by the burst seam is arranged in the fabric strip.
