Abstract

A fastening clip ( 10 ) for mounting a component part ( 28 ), especially an airbag or an airbag module, on a support ( 30 ) includes a head portion ( 12 ), a clip body ( 14 ) and retaining elements ( 16 ) laterally projecting from the clip body ( 14 ) which are elastically deflectable. The clip body ( 14 ) defines an interior and includes windows ( 20 ) through which the retaining elements ( 16 ) protrude outwardly from the interior. An assembly having such fastening clip ( 10 ) furthermore includes a support ( 30 ) having a mounting aperture ( 34 ) matching with the dimensions of the clip body ( 14 ).

First claim

The invention claimed is:

1. A fastening clip ( 10 ) for mounting a component part ( 28 ), especially an airbag or an airbag module, on a support ( 30 ), comprising:
a head portion ( 12 ),
a clip body ( 14 ) extending from the head portion, and
retaining elements ( 16 ) laterally projecting from the clip body ( 14 ) which are elastically deflectable,
wherein the clip body ( 14 ) defines an interior and windows ( 20 ),
and wherein the clip body ( 14 ) includes side walls ( 18 ) in which the windows ( 20 ) are formed and extensions ( 22 ) connected to the side walls ( 18 ) of which the retaining elements ( 16 ) are formed, the retaining elements protruding through the windows outwardly from the interior to extend to the exterior of the clip body and engage the support when the fastening clip mounts the component part on the support.

2. The fastening clip ( 10 ) according to claim 1 , wherein the clip body ( 14 ) and the retaining elements ( 16 ) are formed in one piece.

3. The fastening clip ( 10 ) according to claim 1 , whereby it is completely made of steel.

4. The fastening clip ( 10 ) according to claim 1 , wherein each of the extensions ( 22 ) extends from the side of the side wall ( 18 ) facing away from the head portion ( 12 ) and is bent inwardly so far that holding portions ( 22 b ) of the extension ( 22 ) protrudes outwardly through the window ( 20 ) of the corresponding side wall ( 18 ).

5. The fastening clip ( 10 ) according to claim 4 , wherein the extensions ( 22 ) are bent such that a free end portion ( 22 c ) of the extension ( 22 ) is guided back into the interior.

6. The fastening clip ( 10 ) according to claim 5 , wherein the free end portion ( 22 c ) of the extension ( 22 ) extends farther than the corresponding window ( 20 ) in the direction of the head portion ( 12 ).

7. The fastening clip ( 10 ) according to claim 1 having a blocking means which in a mounted state prevents the retaining elements ( 16 ) from deflecting in the direction of the interior.

8. The fastening clip ( 10 ) according to claim 7 , wherein the blocking means includes first blocking elements at the clip body ( 14 ) and second blocking elements at the retaining elements ( 16 ) which interact at least under the influence of a removal force acting on the fastening clip ( 10 ).

9. The fastening clip ( 10 ) according to claim 8 , wherein the first blocking elements are projections ( 24 ) formed at the windows ( 20 ) and the second blocking elements are bulges ( 26 ) or apertures formed at the corresponding extensions ( 22 ) on the sides facing the projections ( 24 ).

10. The fastening clip ( 10 ) according to claim 9 , wherein the extensions ( 22 ) project from a respective rim of the window ( 20 ) facing away from the head portion ( 12 ) and are directly facing the bulges ( 26 ) or apertures, respectively.

11. An assembly comprising a fastening clip ( 10 ) according to claim 1 and a support ( 30 ) including a mounting aperture ( 34 ) matching with the dimensions of the clip body ( 14 ).

12. The fastening clip according to claim 1 , wherein the clip body, the retaining elements, and the head portion are formed as one piece.

13. The fastening clip according to claim 1 , wherein the head portion engages the component part when the fastening clip mounts the component part on the support.

14. The fastening clip according to claim 1 , wherein relative movement between the component part and the support deforms the extensions.

15. A fastening clip for mounting a component part on a support, comprising:
a head portion;
a clip body extending from the head portion including side walls, the clip body defining an interior and having windows provided on the side walls;
extensions extending from the side walls and defining elastically deflectable retaining elements that protrude through the windows outwardly from the interior to extend to the exterior of the clip body, the retaining elements engaging the support to secure the component part thereto when the clip body extends through an aperture of the component part and a corresponding aperture of the support.

16. The fastening clip according to claim 15 , wherein each of the extensions extends from an end of the side wall spaced away from the head portion and is bent such that holding portions of the extensions protrude outwardly through the window of the corresponding side wall.

17. The fastening clip according to claim 15 , wherein the extensions are bent such that the extensions extend from the exterior of the clip body and back into the interior to locate a free end portion of each of the extensions in the interior.

18. The fastening clip according to claim 15 , wherein the head portion engages the component part when the fastening clip extends through the aperture of the component part and the corresponding aperture of the support.

19. The fastening clip according to claim 15 further comprising blocking means that prevent the retaining elements from deflecting in a direction toward the interior when the fastening clip is in a mounted state, the blocking means including projections extending into the windows and bulges or apertures on the corresponding extensions on a side facing the projections.
