Abstract

Airbag module arrangement for a car is disclosed having an airbag module including an inflatable airbag to protect of at least one occupant of the car, a body section of the vehicle having a fixing point to attach the airbag module. The airbag module arrangement includes a fastening element attached in the fixing point on the body section. An airbag ramp in the direction of steering of the anti-inflatable airbags with an airbag ramp connection attached to the body section which is screwless.

Claims

1. An airbag module arrangement for a vehicle comprising:

an inflatable airbag for protecting at least one occupant of the vehicle;

a fastening module configured to fasten the airbag module to a fastening point on a body section of the vehicle with a fastening element; and

an airbag ramp for directional steering of the inflatable airbag during inflation;

an anti-twisting element for the airbag ramp, the anti-twisting element including a first bead arranged in the body section and a second bead arranged in the airbag ramp;

wherein the airbag ramp is configured to fasten to the body section with a screwless connection such that the first and second beads engage into one another in a form-fit manner and prevent twisting of the airbag ramp.

2. The airbag module arrangement according to claim 1, wherein the airbag ramp is fastened in the fastening point.

3. The airbag module arrangement according to claim 2, wherein the airbag ramp is fastened in the fastening point via the fastening element.

4. The airbag module arrangement to claim 1, wherein the airbag ramp is preassembled on the airbag module and can be fastened in the fastening point of the body section jointly with the airbag module.

5. The airbag module arrangement according to claim 1, wherein the airbag ramp comprises a reaction surface for directional steering the airbag during inflation, wherein the reaction surface projects from the body section at an angle and the fastening point is arranged above the reaction surface.

6. The airbag module arrangement according to claim 1, wherein the airbag ramp comprises at least one support surface with which the airbag ramp supports itself on the body section.

7. The airbag module arrangement according to claim 6, wherein the at least one support surface is arranged below at least one of the fastening point and the reaction surface.

8. The airbag module arrangement according to claim 1, wherein the fastening element comprises an airbag clip, wherein the airbag clip fastens the airbag module and the airbag ramp on the body section against an assembly direction in a form-fit manner.

9. The airbag module arrangement according to claim 1, wherein the anti-twisting device further comprises a connection interface arranged in the airbag ramp and a connection mating interface arranged in the body section and a connection element passing through the connection interface and the connection mating interface, wherein the airbag ramp and the body section are connected to one another in a rotationally fixed manner.

10. The airbag module arrangement according to claim 1, wherein the anti-twisting device is arranged above a reaction surface of the airbag ramp.

11. The airbag module arrangement according to claim 1, wherein the airbag ramp comprises one of a metal component, a plastic component or a fiber composite component.

12. The airbag module arrangement claim 1, wherein the airbag comprises a side airbag.

13. The airbag module arrangement claim 12, wherein the side airbag is selected from the group consisting of a curtain airbag or a roof rail air bag.

14. A vehicle comprising:

a body section having a fastening point;

an airbag module arrangement including an inflatable airbag, a fastening module configured to fasten the airbag module to the fastening point with a fastening element, an airbag ramp for directional steering of the inflatable airbag during inflation, and an anti-twisting element for the airbag ramp, the anti-twisting element including a first bead arranged in the body section and a second bead arranged in the airbag ramp;

wherein the airbag ramp is configured to fasten to the body section with a screwless connection such that the first and second beads engage into one another in a form-fit manner and prevent twisting of the airbag ramp.

15. The vehicle according to claim 14, wherein the body section comprises a portion of a vehicle pillar.
