Abstract: Gas bags for absorbing emergency shocks exerted on automobile occupants in case of collisions, and particularly gas bags made of fabric, are so constructed that the stitched portions will not be torn apart by the inflating pressure of an instantly produced inflating gas. The stitching portions of the gas bags are so constructed that a plurality rows of seams of stitching yarns arrayed along the margin are coarsened toward the outer side such that the tensile load instantaneously exerted on the stitching portions is uniformly dispersed.
