Abstract

A fastening element for fastening an airbag of a vehicle occupant restraint system to a vehicle structure is provided. The fastening element comprising fixing means, by way of which the fastening element can be fixed in a fastening opening of the vehicle structure; and at least one feed-through opening for feeding through a connecting element by way of which the airbag is to be connected to the vehicle structure. The fastening element has at least one projection against which a connecting element of the airbag fed through the feed-through opening rests and which counteracts the connecting element from being pulled out of the feed-through opening. The invention also relates to a method for fastening an airbag of a vehicle occupant restraint system to a vehicle structure.

Claims

1. A fastening element for fastening an airbag of a vehicle occupant restraint system to a vehicle structure comprising

fixing means via which the fastening element can be fixed in a fastening opening of the vehicle structure, and

at least one feed-through opening for feeding through a connecting element (8) via which the airbag is to be connected to the vehicle structure,

wherein at least one projection against which a connecting element of the airbag fed through the feed-through opening rests and which counteracts the connecting element from being pulled out of the feed-through opening and

wherein the fastening element is formed in one piece.

2. The fastening element according to claim 1, wherein the projection projects from an edge of the feed-through opening or forms a section of an edge of the feed-through opening.

3. The fastening element according to claim 1, wherein the projection extends towards the feed-through opening.

4. The fastening element according to claim 1, wherein the fixing means are formed according to the type of a clamp, which can be clamped to the edge of the fastening opening of the vehicle structure.

5. The fastening element according to claim 1, wherein

the fixing means comprise a section, which reaches in the assembled status of the fastening element through the fastening opening of the vehicle structure and rests against a back side of the vehicle structure, which faces away from the airbag to be fixed, and/or

the fixing means comprise a section, which rests in the assembled status of the fastening element against a front side of the vehicle structure facing away from the back side.

6. The fastening element according to claim 5, wherein the section resting against the back side and/or the section of the fixing means resting against the front side form a form fitting and/or force fitting, in particular friction fitting, connection of the fixing means to the back or front side of the vehicle structure.

7. The fastening element according to claim 5, wherein the section of the fixing means resting against the back side is preloaded such that it presses in the assembled status of the fastening element against the backside of the vehicle structure.

8. The fastening element according to claim 5, wherein the section of the fixing means resting against the front side is preloaded such that it presses in the assembled status of the fastening element against the front side of the vehicle structure.

9. The fastening element according to claim 5, wherein the section resting against the back side and/or the section of the fixing means resting against the front side comprises at least one projection.

10. The fastening element according to claim 5, wherein the fastening element comprises a longitudinal shape and the section of the fixing means resting against the back side is being formed at an end of the fastening element being bent off relative to the remaining fastening element.

11. The fastening element according to claim 5, wherein the section of the fixing means resting against the front side projects flap like from the remaining fastening element.

12. The fastening element according to claim 5, wherein the section of the fixing means resting against the front side projects flap like from an edge of an opening of the fastening element being different from the feed-through opening.

13. The fastening element according to claim 1, further comprising at least one further feed-through opening for feeding through the connecting element.

14. The fastening element according to claim 1, further comprising at least one recess, which continuous from the feed-through opening and/or the further feed-through opening to an edge of the fastening element, such that the connecting element can be inserted through the recess into the feed-through opening or the further feed-through opening.

15. The fastening element according to claim 14, further comprising at least one further feed-through opening for feeding through the connecting element, wherein the fastening element is formed longitudinally and the recess continuous from one front face of an end of the fastening element to the further feed-through opening, such that the connecting element can be inserted via the front face into the further feed-through opening.

16. The fastening element according to claim 14, further comprising at least one further feed-through opening for feeding through the connecting element, wherein the fastening element is formed longitudinally and the recess continuous from a lateral edge of the fastening element to the further feed-through opening such that the connecting element can be inserted via the lateral edge into the further feed-through opening.

17. The fastening element according to claim 1, further comprising a first and a second further feed-through opening as well as a first and a second recess, wherein the first recess continuous from a lateral edge of the fastening element to the first further feed-through opening and the second recess continuous from a front face of an end of the fastening element to the second further feed-through opening.

18. The fastening element according to claim 1, wherein the feed-through opening is spaced apart from the fixing means such that it is positioned in the assembled status of the fastening element spaced apart from the fastening opening of the vehicle structure.

19. An arrangement of an airbag, a fastening element according to claim 1 and a connecting element fed through the feed-through opening of the fastening element.

20. A method for fastening an airbag to a vehicle structure with the steps of:

providing a fastening element, which comprises at least one feed-through opening and at least one projection and which is formed in one piece;

feeding through the connecting element via which the airbag is to be connected to the vehicle structure through the feed-through opening, such that the connecting element rests against the projection and thus counteracts the connecting element from being pulled out of the feed-through opening; and

inserting the fastening element into a fastening opening of a vehicle structure.
