Abstract

The invention relates to a gas bag module, comprising at least one mounting part and at least one piece of fabric material which is stressed on activation of the gas bag module and which is provided with at least one opening. The gas bag module further comprises a force-transmitting device by which the piece of fabric material is fastened to the mounting part. The device comprises a first rivet reinforcing the opening in the piece of fabric material, and a second rivet penetrating the first rivet and connecting the piece of fabric material with the mounting part.

Claims

1. A gas bag module, comprising

at least one mounting part,

at least one piece of fabric material which is stressed on activation of said gas bag module and which is provided with at least one opening, and

a force-transmitting device by which said piece of fabric material is fastened to said mounting part,

the device comprising a first rivet reinforcing said opening in said piece of fabric material, and a second rivet penetrating said first rivet and connecting said piece of fabric material with said mounting part.

2. The gas bag module according to claim 1, wherein said piece of fabric material is a gas bag.

3. The gas bag module according to claim 1, wherein said piece of fabric material is a tether.

4. The gas bag module according to claim 1, wherein said mounting part is an emblem.

5. The gas bag module according to claim 1, wherein a separate adjoining part is provided and said piece of fabric material is fastened by said first rivet to said separate adjoining part to form a unit, and wherein said unit is fastened to said mounting part by said second rivet.

6. The gas bag module according to claim 5, wherein said part with which said piece of fabric material forms said unit is made of plastic.

7. The gas bag module according to claim 6, wherein it is provided with a covering, said part of plastic constituting said covering of said gas bag module.

8. The gas bag module according to claim 5, wherein on an edge of said separate adjoining part said piece of fabric material is folded over said edge and covers said part on opposite sides and wherein said first rivet holds together said folded-over section of said piece of fabric material and said part to form a unit.

9. The gas bag module according to claim 1, wherein said piece of fabric material is a gas bag having an inflation orifice, said gas bag being fastened in a region of said inflation orifice to said mounting part.
