Air bag arrangement for a vehicle-occupant-restraining system and method for producing an airbag arrangement

1. An airbag arrangement for a vehicle-occupant-restraining system, comprising

an airbag, wherein at least one airbag layer delimits an inflatable volume of the airbag; and

at least one fastening tab, which is connected to the airbag layer and is intended for fastening the airbag on a vehicle component, wherein the fastening tab is formed at least partially in two layers,

wherein the entire fastening tab is formed from a different material to that of the airbag layer,

wherein the fastening tab has at least one fastening opening through which to guide a fastening element,

and wherein the layers of the fastening tab are connected to one another in a region of the fastening tab which is remote from the airbag and which comprises the fastening opening, and

wherein one of the layers of the fastening tab is connected to a first airbag layer and the other layer of the fastening tab is connected to a second airbag layer.

2. The airbag arrangement according to claim 1 , wherein the fastening tab has two layers connected to one another in one piece.

3. The airbag arrangement according to claim 1 , wherein the fastening tab is formed at least partially as a single layer.

4. The airbag arrangement according to claim 1 , wherein the fastening tab is formed from a woven-fabric material.

5. The airbag arrangement according to claim 4 , wherein the fastening tab is formed from a woven-fabric material for producing a belt strap of a vehicle seat-belt arrangement.

6. The airbag arrangement according to claim 1 , wherein the material of the fastening tab has a higher tear strength than the material of the airbag layer.

7. The airbag arrangement according to claim 1 , wherein the fastening tab is connected to the airbag layer via a seam or by bonding.

8. The airbag arrangement according to claim 7 , wherein the seam is a circumferential seam or a peripheral seam which delimits the inflatable volume of the airbag at least partially.

9. The airbag arrangement according to claim 8 , further comprising a rotation-prevention device, which counteracts rotation of a fastening element guided through the fastening opening.

10. The airbag arrangement according to claim 7 , wherein the seam differs from a circumferential seam or peripheral seam which delimits the inflatable volume of the airbag at least partially.

11. The airbag arrangement according to claim 1 , wherein the fastening tab projects from a periphery of the airbag or projects beyond the periphery of the airbag.

12. The airbag arrangement according to claim 1 , wherein a periphery of the fastening opening is strengthened and/or reinforced at least partially.

13. The airbag arrangement according to claim 1 , wherein the fastening opening is rectangular or oval.

14. The airbag arrangement according to claim 1 , wherein the fastening tab has at least one strengthened and/or reinforced portion, at least part of which extends on a side of the fastening opening which is directed away from the airbag.

15. A method for producing an airbag arrangement for a vehicle-occupant-restraining system, having the following steps:

providing an airbag, which has at least one airbag layer delimiting an inflatable volume of the airbag;

connecting a fastening tab to the airbag layer in order for the airbag to be fastened on a vehicle component, wherein the entire fastening tab is formed from a different material to that of the airbag layer;

wherein the fastening tab is formed at least partially in two layers and includes at least one fastening opening through which to guide a fastening element; and

connecting the layers of the fastening tab together in a region of the fastening tab which is remote from the airbag and which includes the fastening opening, and

wherein one of the layers of the fastening tab is connected to a first airbag layer and the other layer of the fastening tab is connected to a second airbag layer.
