Abstract

A gas bag module comprises a gas generator (16) and a generator carrier (12), to which the gas generator (16) is fastened and via which the gas generator (16) can be fastened directly or indirectly to a vehicle steering wheel. The generator carrier (12) consists at least partially of a multiple-component plastic (30, 32). There is further proposed a vehicle steering wheel including such gas bag module.

Claims

1. A gas bag module, comprising

a gas generator (16) and

a generator carrier (12), to which said gas generator (16) is fastened and via which said gas generator (16) can be fastened directly or indirectly to a vehicle steering wheel,

characterized in that said generator carrier (12) consists at least partially of a multiple-component plastic (30, 32), said components defining different layers of said carrier (12).

2. The gas bag module according to claim 1, characterized in that said generator carrier (12) has a base section (19) with detent elements (20) formed thereon, by means of which detent elements said generator carrier (12) can be fastened on a steering wheel side.

3. The gas bag module according to claim 2, characterized in that said detent elements (20) consist at least partially of a multiple-component plastic (30, 32).

4. The gas bag module according to claim 1, characterized in that said multiple-component plastic consists of a carrier material (30) and a coating (32).

5. The gas bag module according to claim 1, characterized in that said generator carrier (12) has a cup-shaped construction with a depression (14) in which said gas generator (16) is arranged.

6. The gas bag module according to claim 5, characterized in that a covering cap (26) is provided, which can be inserted into said depression (14), and that said depression (14) is constructed such that said covering cap (26) closes said generator carrier externally.

7. The gas bag module according to claim 5, characterized in that said depression (14) has an edge (22) with at least one section (24) formed thereon so as to project laterally.

8. The gas bag module according to claim 7, characterized in that said projecting section (24) consists of a multiple-component plastic (30, 32).

9. A vehicle steering wheel with a gas bag module comprising a gas generator (16) and a generator carrier (12), to which said gas generator (16) is fastened and via which said gas generator (16) can be fastened directly or indirectly to a vehicle steering wheel, said generator carrier (12) consisting at least partially of a multiple-component plastic (30, 32), said components defining different layers, said generator carrier (12) having a cup-shaped construction with a depression (14) in which said gas generator (16) is arranged, and at least one projecting section (24) being formed on an edge of said recess (14), characterized in that said projecting section (24) forms a part of a surface of said steering wheel (100) which is visible from the exterior.

10. The vehicle steering wheel according to claim 9, characterized in that said gas bag module is mounted so as to be movable in axial direction.
