Abstract

A fixing element fixes a part to a support wall. When the fixing element is inserted into an opening in the support wall and reaches a predetermined end position, the fixing element locks to the support wall. The fixing element includes a stop element, a snap-on element, and an unlocking element. The stop element bears against a side of the support wall when the fixing element is locked to the support wall. The snap-on element is positioned on an inner side of the support wall when the fixing element is locked to the support wall. The unlocking element is connected to the snap-on element. The unlocking element is configured to permit the snap-on element to be unlocked and the fixing element to be removed from the opening. An installation tool and a testing tool may be used in conjunction with the fixing element.

Claims

1. An airbag arrangement for a vehicle restraint system with at least one inflatable airbag and at least one fixing element for fastening the airbag to a vehicle body, the fixing element reaching through a fastening opening of the airbag, the airbag arrangement further comprising an anti-twist protection which is distinct from the airbag and which prevents the fixing element from twisting in the fastening opening before the airbag is fastened to the vehicle body.

2. The airbag arrangement according to claim 1, wherein the anti-twist protection has an opening through which the fixing element reaches and which is designed in such a manner that the fixing element cannot be twisted in it.

3. The airbag arrangement according to claim 1, wherein the anti-twist protection is connected to the airbag.

4. The airbag arrangement according to claim 1, wherein the airbag is formed from material layers sewn to one another by means of a circumferential seam and the anti-twist protection is sewn on to the airbag by means of the circumferential seam.

5. The airbag arrangement according to claim 1, wherein the airbag has a fastening tab in which the fastening opening through which the fixing element reaches is arranged.

6. The airbag arrangement according to claim 5, wherein the anti-twist protection is connected to the fastening tab.

7. The airbag arrangement according to claim 6, wherein the anti-twist protection is arranged at least in some sections between two material layers of the fastening tab.

8. The airbag arrangement according to claim 6, further comprising a pocket which is formed by material layers of the fastening tab and into which at least some sections of the anti-twist protection are pushed.

9. The airbag arrangement according to claim 6, wherein the fastening tab is formed by folding over the free end of a tab formed on the airbag, and the anti-twist protection is arranged between the folded-over and not folded-over sections of the tab.

10. The airbag arrangement according to claim 1, wherein the anti-twist protection has a section which can be folded over onto the head of the fixing element.

11. The airbag arrangement according to claim 1, wherein the anti-twist protection protrudes out of the fastening tab with a section and this section can be folded over onto the head of the fixing element.

12. The airbag arrangement according to claim 1, wherein the anti-twist protection additionally forms a holder for holding the folded airbag.

13. The airbag arrangement according to claim 12, wherein the anti-twist protection has two parts which are connected rotatably to each other at one end in each case and the free ends of which are folded onto each other and connected in such a manner that the folded airbag is embraced by the two parts.
