Abstract

A gas bag module of a vehicle occupant restraint system has a substantially tubular gas generator, a gas bag, and a gutter-shaped mounting housing surrounding the gas generator. The mounting housing is provided with an elongated slot for fastening of the gas generator to a vehicle and has opposite walls delimiting the elongated slot. The walls have terminal edges and are bent in a U-shape to define portions with a double layer. The layer of both portions which is provided with the terminal edge extend towards the gas generator so that the terminal edge lies against the gas generator.

Claims

1. A gas bag module of a vehicle occupant restraint system, having

a substantially tubular gas generator,

a gas bag, and

a gutter-shaped mounting housing surrounding said gas generator,

said mounting housing being provided with an elongated slot for fastening of said gas generator to a vehicle and having opposite walls delimiting said elongated slot,

said walls having terminal edges and being bent in a U-shape to define portions with a double layer, and

the layer of both portions, which is provided with said terminal edge, extending towards said gas generator so that said terminal edge lies against said gas generator.

2. The gas bag module according to claim 1, wherein said portions of said walls having said double-layer extend laterally outwards and form two flanges for fastening of said mounting housing to the vehicle.

3. The gas bag module according to claim 2, wherein said portions of said walls having said double-layer include an obtuse angle with each other.

4. The gas bag module according to claim 2, wherein said gas bag has an inflation orifice and is fastened to said flanges via a frame piece placed in the gas bag and surrounding said inflation orifice.

5. The gas bag module according to claim 4, wherein said gas bag has a wall section surrounding said inflation orifice, said wall section being clamped between said frame piece and said flanges.

6. The gas bag module according to claim 2, wherein said flanges have fastening openings.
