Abstract

An airbag can include a covering that surrounds an interior space that can be filled with gas, a gas-conducting pipe which is stretched longitudinally along a direction of extent, and a contact region of the covering that surrounds the inflow opening and encloses the gas-conducting pipe in a sealing manner along a circumferential direction of the gas-conducting pipe that encircles the direction of extent. A protective layer of the covering can be arranged, at least in some sections in the interior space of the covering, with respect to the gas-conducting pipe so that damage to the covering during filling of the interior space of the covering with hot gas can be prevented by the protective layer. At least one fastening region of the protective layer, via which the protective layer can be connected to the covering, can be connected to the contact region of the covering.

Claims

1. Airbag arrangement for a motor vehicle, comprising

an inflatable airbag;

a gas-conducting pipe with which gas released by a gas generator can be conducted into the airbag to inflate it, wherein

the gas-conducting pipe comprises an end region on which an outflow opening is located; and

a profile that is fixed to the gas-conducting pipe and that comprises a continuous covering surface which lies opposite the outflow opening.

2. Airbag arrangement as claimed in claim 1, wherein the profile is essentially L-shaped.

3. Airbag arrangement as claimed in claim 1, wherein the covering surface is distanced from the outflow opening.

4. Airbag arrangement as claimed in claim 1, wherein the covering surface extends parallel to the outflow opening.

5. Airbag arrangement as claimed in claim 1, wherein the profile is fixed to the end region of the gas-conducting pipe and adjacent to the outflow opening.

6. Airbag arrangement as claimed in claim 5, wherein the profile comprises a section that is fixed to the gas-conducting pipe and which extends essentially perpendicular to the covering surface.

7. Airbag arrangement as claimed in claim 1, wherein the gas-conducting pipe has an essentially cylindrical shape.

8. Airbag arrangement as claimed in claim 7, wherein the covering surface lies opposite the outflow opening along the direction of extent of the gas-conducting pipe.

9. Airbag arrangement as claimed in claim 8, wherein the gas-conducting pipe is introduced through an opening of a covering of the airbag.

10. Airbag arrangement as claimed in claim 1, wherein the covering surface is configured to ensure that no part of an airbag layer of the airbag can enter the outflow opening.
