Abstract

A gas bag module has a generally cylindrical gas generator, at least one igniter and a housing to which the gas generator is secured. The igniter extends radially out of the gas generator and is secured to the housing. A gas bag is arranged in the housing and is clamped between the gas generator and the housing.

Claims

1. A gas bag module having a generally cylindrical gas generator, at least one igniter and a housing to which said gas generator is secured, said igniter extending radially out of said gas generator and being secured to said housing, and a gas bag which is clamped between said gas generator and said housing.

2. The gas bag module according to claim 1, characterized in that said igniter extends out of said housing through an opening in said housing.

3. The gas bag module according to claim 1, characterized in that said igniter is provided with a holding geometry by means of which it is arrested at said housing so that said gas generator is firmly connected to said housing.

4. The gas bag module according to claim 3, characterized in that said holding geometry is a male thread onto which a nut is screwed so that said gas generator is firmly screwed together with said housing.

5. The gas bag module according to claim 3, characterized in that said holding geometry is a groove in which a holding ring is inserted so that said gas generator is firmly connected to said housing.

6. The gas bag module according to claim 1, characterized in that said housing comprises a trough-shaped receiving section for said gas generator.

7. The gas bag module according to claim 1, characterized in that said gas generator is located in the interior of said gas bag.
