Abstract

A gas bag module for a vehicle occupant restraint system, comprises a gas bag having a folded part, a gas generator for generating compressed air, a pressure chamber housing, in which the gas generator is arranged, which surrounds the gas generator and in which the generated compressed gas spreads, and an ejection channel in which the folded part of the gas bag is arranged and which predefines an unfolding direction upon inflation of the gas bag. The ejection channel is constructed as a box-shaped separate part with a flange. The pressure chamber housing has a counter flange. The ejection channel is attached to the housing by attaching the flange to the counter flange. The gas bag is clamped immediately between the flange and the counter flange. Further the invention relates to a method for assembling parts of an air bag module to each other for shipping purposes and for installation into a vehicle.
