Abstract

A device for fixing an airbag which is fastened to a holding frame in a housing of a front passenger airbag module by means of at least one clamping element arranged separately from the holding frame. The housing and the clamping element are non-deformable in the region of the holding frame. The clamping element is free from screw or rivet connections and is dimensioned so that it is spaced from the holding frame when being introduced into the clamping position by a distance which is greater than the thickness of an optionally provided protective film for the airbag. The clamping element is fixed in its clamping position at a distance from the holding frame.

Claims

1. A device for fixing an airbag which is fastened to a holding frame in a housing of a front passenger airbag module by means of at least one clamping element arranged separately from the holding frame,

wherein the housing and the clamping element are non-deformable in the region of the holding frame,

wherein the clamping element is free from screw or rivet connections and is dimensioned so that the clamping element is spaced from the holding frame when being introduced into the clamping position by a distance which is greater than the thickness of an optionally provided protective film for the airbag, and

wherein the clamping element is fixed in a clamping position at a distance from the holding frame.

2. The device as claimed in claim 1, wherein the clamping element can be pushed over the holding frame from the outside through holes in the housing and the clamping element has at least one latching section for fixing it in the clamping position at a distance from the holding frame, with which the latching section is associated with at least one latching section in the housing.

3. The device as claimed in claim 2, wherein the housing has two latching sections for the clamping element, of which a first latching section is located on the side wall of the housing and a second latching section is located on the outside of the underside of the housing.

4. The device as claimed in claim 3, wherein at least one respective clamping element is provided on opposite sides of the holding frame.

5. The device as claimed in claim 4, wherein a plurality of individual clamping elements are provided.

6. The device as claimed in claim 4, wherein clamping strips are provided.

7. The device as claimed in claim 1, wherein a two-part housing is provided, each housing part having clamping elements therein.

8. The device as claimed in claim 7, wherein at least two projections located at a distance opposite one another are provided as the clamping elements.

9. The device as claimed in claim 8, wherein the housing parts are connected via at least one hinge and are connectable to one another at opposite end faces.

10. The device as claimed in claim 9, wherein latching elements are provided as the connecting elements.

11. The device as claimed in claim 10, wherein screws are provided as the connecting elements.
