Abstract

An airbag module has a housing with side walls and a base plate, on which a gas generator is mounted. A cover plate is located on the free ends of the side walls for closing the airbag module. The housing is provided with a latching or snap-action device for the latching arrangement of the airbag module on a component of the vehicle, in particular on a steering wheel. The latching device is formed as an integral part of the housing on the side walls and/or on the base plate of the housing, such that the airbag module is mounted solely by the latching device on the appropriate part of the vehicle.

Claims

1. An airbag module comprising:

a housing that has side walls that have free ends;

a base plate on which a gas generator is mounted;

a cover plate located on the free ends of the side walls for closing the airbag module;

the housing is provided with a latching device for the mounting of the airbag module on a vehicle component, wherein the latching device is an integral part of the housing on the side walls and/or the base plate of the housing such that the airbag module is mounted on the vehicle component solely by the latching device.

2. The airbag module according to claim 1 wherein the vehicle component is a steering wheel.

3. The airbag module according to claim 1, wherein the latching device comprises elastically deformable spring elements.

4. The airbag module according to claim 1, wherein the latching device cooperates with a component of the vehicle in the form of latching lugs for latching the airbag module to the vehicle component such that the latching device engages the latching lugs.

5. The airbag module according to claim 1, wherein the latching device cooperates with a component of the vehicle in the form of latching openings for latching the airbag module to the vehicle component such that the latching device engages the latching openings.

6. The airbag module according to claim 1, wherein for removal of the airbag module is removably mounted on the vehicle component.

7. The airbag module according to claims 1, wherein the latching device comprises spring elements, which are formed on the side walls of the airbag module and project outwards therefrom, the free ends of which engage behind corresponding latching lugs located on the vehicle.

8. The airbag module according to claim 1, wherein the latching device comprises spring elements, which are formed on the base plate of the airbag module and extend substantially vertically away from said base plate.

9. The airbag module according to claim 7, wherein the spring elements have recesses therein, into which latching lugs located on the vehicle component engage.

10. The airbag module according to claim 7, wherein the spring elements have openings therein, into which latching lugs located on the vehicle component engage.

11. The airbag module according to claim 8, wherein the spring elements have recesses therein, into which latching lugs located on the vehicle component engage.

12. The airbag module according to claim 8, wherein the spring elements have openings therein, into which latching lugs located on the vehicle component engage.

13. The airbag module according to claim 8, wherein the spring elements located on the base plate are formed from parts bent away from the free edge of the base plate.

14. The airbag module according to claim 11, wherein the spring elements located on the base plate are formed from parts bent away from the free edge of the base plate.

15. The airbag module according to claim 12, wherein the spring elements located on the base plate are formed from parts bent away from the free edge of the base plate.

16. The airbag module according to claim 3, wherein the base plate has an opening therein for receiving at least a portion the gas generator and the spring elements located on the base plate comprise parts which are bent away from the region of the base plate delimiting said opening.

17. The airbag module according to claim 3, wherein the spring elements of the base plate are coated with a plastic material.

18. A steering wheel having an airbag module mounted on the steering wheel, wherein the airbag module comprises:

a housing that has side walls that have free ends;

a base plate on which a gas generator is mounted;

a cover plate located on the free ends of the side walls for closing the airbag module;

the housing is provided with elastically deformable spring elements for the mounting of the airbag module on steering wheel wherein the spring elements are an integral part of the housing on the side walls and/or the base plate of the housing such that the airbag module is mounted on the vehicle steering wheel solely by the spring elements.
