Abstract

In a gas bag module for a vehicle occupant restraint system, a gas generator is held on a trough-shaped carrier part inbetween a diffusor cap, surrounding it, and the base of the carrier part by means of a clamping ring, by which the rim of the inflation opening of a gas bag is fastened to the carrier part.

Claims

1. A gas bag module for a vehicle occupant restraint system, comprising:

a trough-shaped carrier part with a base,

a gas generator,

a gas bag with a rim forming an inflation opening,

a clamping ring, and

a diffuser cap surrounding said gas generator, wherein said clamping ring secures said rim forming said inflation opening to said carrier part and said gas generator is held between said diffuser cap and said base of said carrier part, wherein said gas generator is held between said diffuser cap and said base of said carrier part with an interlocking fit, and

wherein said gas generator has a housing with at least one integrally formed pin and an integrally formed socket, said diffuser cap forms a first opening and said base of said carrier part forms a second opening, said pin of said housing fitting in said first opening and said socket of said housing being constructed so as to adapt to said second opening.

2. The gas bag module according to claim 1, wherein said opening at said base of said carrier part is rimmed by a concave wall region being in snug contact with said housing of said gas generator.
