Abstract

An airbag arrangement for a vehicle occupant restraint system is provided. The airbag arrangement comprising an inflatable airbag for protecting a vehicle occupant, a fastening element for fastening the airbag to a support structure, and means for counteracting a torquing of the fastening element pre-mounted at the airbag, wherein the means comprise an opening through which the pre-mounted fastening element reaches, said opening being designed to counteract a torquing of the pre-mounted fastening element. The opening comprises two sections that cross one another.

Claims

1. An airbag arrangement for a vehicle occupant restraint system comprising

an inflatable airbag for protecting a vehicle occupant,

a fastening element for fastening the airbag to a support structure, and

means for counteracting a torquing of the fastening element pre-mounted at the airbag, whereby

the means comprise an opening through which the pre-mounted fastening element reaches and which is designed to counteract a torquing of a pre-mounted fastening element,

wherein the opening comprises two sections that cross one another.

2. The airbag arrangement according to claim 1, wherein

the fastening element comprises two arms being opposed to each other via which said fastening element is lockable on the support structure and,

one of the sections of the opening crossing each other is designed such that the arms of the fastening element can reach through said section without being pressed together.

3. The airbag arrangement according to claim 1, wherein the sections crossing each other are formed longitudinal.

4. The airbag arrangement according to claim 1, wherein

the opening is formed in a part different from the fastening strap which is connected to the fastening strap.

5. The airbag arrangement according to claim 4, wherein the part is arranged with one side of the fastening strap which faces away from the support structure in the assembled status of the airbag.

6. The airbag arrangement according to claim 1, wherein the opening is formed in a fastening strap via which the airbag can be mounted at the support structure.

7. The airbag arrangement according to claim 6, wherein the fastening strap has a first section and a second section, which is folded in direction of the first section, and the opening is formed in one of the two sections.

8. The airbag arrangement according to claim 7, wherein

the second section of the fastening strap comprises the opening counteracting a torquing of the pre-mounted fastening element,

the first section comprises an opening, which aligns with the opening in the second section, whereby

the opening is only formed in the second section for counteracting a torquing of the pre-mounted fastening element.

9. The airbag arrangement according to claim 7, wherein the second section of the fastening strap faces away from the support structure in the assembled status of the airbag.

10. The airbag arrangement according to claim 9, wherein

the fastening element in the assembled status rests against a side of the fastening strap with a sub-section, which faces away from the support structure, whereby

the second section of the fastening strap is designed such that the sub-section of the fastening element rests only against the first section of the fastening strap.

11. The airbag arrangement according to claim 10, wherein

the sub-section resting against the fastening strap is formed by two contact surfaces of the fastening element being distanced from each other, and

the width of the second section of the fastening strap in the area of the opening is smaller than the distance of the two contact surfaces in the assembled status of the fastening element.

12. An airbag arrangement for a vehicle occupant restraint system, in particular according to claim 1, comprising

an inflatable airbag for protecting a vehicle occupant,

a fastening strap connected to the airbag via which the airbag can be fastened to a support structure whereby

a first opening is formed in the fastening strap,

a fastening element for fastening the airbag to the support structure, which reaches through the first opening in the assembled status of the airbag, and

means for counteracting a torquing of the fastening element pre-mounted at the airbag, whereby

the means comprise a second opening in a part different from the fastening strap through which the pre-mounted fastening element reaches and being designed for counteracting a torquing of the pre-mounted fastening element,

wherein the part is formed in a clamp-like manner with the second opening such that it can be clamped to the fastening strap.

13. The airbag arrangement according to claim 12, wherein the part has a first section and a second section, which is bend in the direction of the first section.

14. The airbag arrangement according to claim 13, wherein the second opening is formed in the second section of the part, whereby the second section faces away from the support structure in the assembled status of the assembled status of the airbag.

15. The airbag arrangement according to claim 14, wherein the first section of the part has an opening which aligns with the second opening.

16. A vehicle with an airbag arrangement according to claim 1.
