Abstract

A gas bag for a vehicle occupant restraint system comprises a flexible wall which defines several sides of the gas bag. The flexible wall has on at least one of its sides at least one fold in the inflated state of the gas bag, the fold being defined by permanently connected adjacent sections of the wall. The wall further comprises at least one seam for the connection of the adjacent sections so that the flexible wall is shortened on the side and, therefore, the geometrical shape of the gas bag is modified compared with the gas bag of similar configuration but without the seam.
