Abstract

An airbag module is provided having an airbag, or gas generator for filling the airbag, and a housing for receiving the airbag in the unfilled state, which has a front side, in which an airbag exit opening is implemented, the front side having a surface structure which prevents a flat contact of the airbag exit opening on a plane.

Claims

1. An airbag module, comprising:

a gas generator adapted to fill the airbag; and

a housing adapted to receive the airbag in an unfilled state, which has a front side in which an airbag exit opening is implemented;

wherein the front side has a surface structure that prevents a flat contact of the airbag exit opening on a plane.

2. The airbag module according to claim 1, wherein the front side has the surface structure that prevents a tilt-stable storage of the airbag module having its front side on the plane.

3. The airbag module according to claim 2, wherein the front side has the surface structure in a form of a spherical part.

4. The airbag module according to claim 3, wherein the surface structure has a contact plane that forms an angle (α

) greater than approximately 0°

.

5. The airbag module according to claim 1, wherein the surface structure is implemented so that at least one gap results between the front side and the plane when the front side of the airbag module is in contact with the plane.

6. The airbag module according to claim 1, wherein at least one projection is implemented on the front side.

7. The airbag module according to claim 6, wherein the at least one projection is implemented in a form of a pin.

8. The airbag module according to claim 6, wherein the at least one projection is removably fastened on the housing.

9. The airbag module according to claim 6, wherein the at least one projection is permanently fastened on the housing.

10. The airbag module according to claim 6, wherein the at least one projection comprises at least one opening.

11. The airbag module according to claim 6, wherein the at least one projection comprises a contour to be received in a recess that is implemented in a passenger compartment element.

12. The airbag module according to claim 6, wherein the at least one projection is implemented as a guide wing.

13. The airbag module according to claim 1, wherein the airbag exit opening comprises a panel that can be opened by the airbag.

14. The airbag module according to claim 1, wherein the gas generator is situated on an opposite side of the housing that is opposite to the front side.

16. The airbag module according to claim 2, wherein the front side has the surface structure in a form of a cylindrical part.

17. The airbag module according to claim 2, wherein the front side has the surface structure in a form of a conical part.

18. The airbag module according to claim 3, wherein the surface structure has a contact plane that forms an angle (α

) greater than between approximately 5° and

approximately 45°

with the plane in which the airbag exit opening lies.
