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,

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

wherein the opening is a cross-shaped opening.

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 wherein the opening comprises two sections of the opening that partially overlay each other, and wherein one of the two sections of the opening is designed such that the arms of the fastening element can reach through said one of the two sections without being pressed together.

3. The airbag arrangement according to claim 1, wherein the opening comprises two sections that partially overlay each other, and wherein the two sections are formed longitudinally so as to form the cross-shape.

4. The airbag arrangement according to claim 1, wherein the opening is formed in a part different from a fastening strap via which the airbag is mountable to the structure, and wherein the part 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 facing away from the support structure in an assembled status of the airbag.

6. The airbag arrangement according to claim 1, wherein the cross-shaped opening is formed in a fastening strap via which the airbag can be mounted to 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 first and second sections.

8. The airbag arrangement according to claim 7, wherein the second section of the fastening strap has the cross-shaped opening designed to act counteract the torquing of the pre-mounted fastening element, and

wherein the first section comprises an additional opening, which aligns with the cross-shaped opening in the second section.

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

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

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

14. 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 wherein one of the two sections of the opening is designed such that the arms of the fastening element can reach through said one of the two sections without being pressed together.

15. The airbag arrangement according to claim 1, wherein the part with the opening is formed as a part different from a fastening strap via which the airbag is mountable to the support structure.

16. The airbag arrangement according to claim 15, wherein the part is arranged with one side of the fastening strap facing away from the support structure in an assembled status of the airbag.

13. An airbag arrangement for a vehicle occupant restraint system comprising:

an inflatable airbag configured to protect a vehicle occupant,

a fastening element configured to fasten the airbag to a support structure, and

a part configured to counteract a torquing of the fastening element pre-mounted at the airbag,

wherein the part includes an opening through which the pre-mounted fastening element reaches and which is designed to counteract the torquing of the pre-mounted fastening element, and

wherein the opening is a cross-shaped opening having two sections that partially overlaying each other.
