A method of folding a gas bag for a vehicle occupant restraint system is disclosed, this gas bag having a wall delimiting a chamber and having an inflation opening, the inflation opening having a rim. The method comprises the following steps: First, the gas bag is spread out on a base. Then, the rim of the inflation opening of the gas bag is held fixed. Thereafter, a plate is arranged parallel to the base and at a distance therefrom, so that the gas bag extends between the base and the plate. Subsequently, the chamber of the gas bag is exposed to a pressurized medium, so that the gas bag unfolds between the base and the plate. Finally, the wall of the gas bag is pressed inwards at a plurality of sites distributed over a circumference of the gas bag. Further, a gas bag folded by performing this method and a device for performing the method are disclosed.

A gas bag module of a vehicular passenger restraint system has a gas bag stowable on one side of a mounting wall and, for inflating the gas bag, a gas generator mountable on the opposite side of this mounting wall. An inflation opening of the gas bag is provided with a bead which grips behind the mounting wall.
