Abstract

An airbag for an airbag module of a motor vehicle, having an airbag sleeve which surrounds an interior of the airbag which is formed by at least two airbag parts which are connected to one another, and an insertion opening of the airbag sleeve through which an assembly of the airbag module which is to be arranged inside the airbag can be inserted into the interior of the airbag and which is formed by an interruption of the connection between the two airbag parts so that the two airbag parts each form one edge section of the insertion opening, and an assembly of the airbag module which is arranged in the interior of the airbag and can be inserted into the airbag through the insertion opening, in each case one clip protruding from each of the two edge sections of the insertion opening.

Claims

1. An airbag for a motor vehicle airbag module, comprising:

an airbag sleeve which surrounds an interior of the airbag which can be filled with gas and which is formed by at least two airbag parts which are connected to one another, and an insertion opening of the airbag sleeve formed by an interruption of the connection between the two airbag parts so that the two airbag parts each form one edge section of the insertion opening;

a pair of clips, each of the clips protruding from one of the two edge sections of the insertion opening;

wherein each of the two clips are formed from at least one flexible material section, and wherein the at least one material section of the one clip being embodied congruent with respect to the at least one material section of the other clip in a spread out flat state.

2. The airbag of claim 1, wherein each of the two airbag parts comprise a first fabric layer and wherein each of the clips are integrally formed with one of the first fabric layers.

3. The airbag of claim 2, wherein each of the first fabric layers are congruent in a spread out flat state.

4. The airbag of claim 3, wherein the airbag parts each include a second fabric layer which bears in each case in front of an inner side of a first fabric layer which faces the interior of the airbag sleeve.

5. The airbag of claim 4, wherein the second fabric layers are congruent in a spread out flat state.

6. The airbag of claim 5, wherein the clip assigned to the respective airbag part is formed by part of one of the second fabric layers.

7. An airbag module for a motor vehicle airbag module, comprising:

an airbag including an airbag sleeve which surrounds an interior of the airbag which can be filled with gas and which is formed by at least two airbag parts which are connected to one another, and an insertion opening of the airbag sleeve formed by an interruption of the connection between the two airbag parts so that the two airbag parts each form one edge section of the insertion opening;

a pair of clips, each of the clips protruding from one of the two edge sections of the insertion opening;

wherein each of the two clips are formed from at least one flexible material section, and wherein the at least one material section of the one clip being embodied congruent with respect to the at least one material section of the other clip in a spread out flat state;

a gas generator located in the interior of the airbag and can be inserted into the airbag through the insertion opening.

8. The airbag module of claim 7, wherein the clips are laid around the gas generator in such a way that they at least partially engage around the gas generator, and in that the two clips overlap.

9. The airbag module of claim 8, wherein in an overlapping region of the two clips the one clip at least partially covers the other clip so that the other clip extends between the one clip and the gas generator.

10. The airbag module of claim 9, wherein a mounting element which engages through a mounting opening of the clip protrudes from the gas generator in order to secure the at least one clip to the assembly.

11. The airbag module of claim 10, wherein one clip covers the insertion opening on the outside of the airbag sleeve facing away from the interior of the airbag.

12. The airbag module of claim 7, wherein another clip is led into the interior of the airbag through the insertion opening and extends on the inside of the airbag sleeve, in front of the insertion opening.

13. The airbag module of claim 7, wherein each of the clips extends essentially along the entire assigned edge section of the insertion opening so that the edge of the insertion opening is bounded essentially completely by the clips.

14. The airbag module of claim 7, wherein the insertion opening is essentially closed off by the clips which cover one another.

15. The airbag module of claim 7, wherein the insertion opening is closed off by the clips except for a passage for an electric connecting cable.

16. The airbag module of claim 7, wherein the insertion opening is closed off by the overlapping clips except for a partial opening through which the gas generator partially projects out of the interior of the airbag.

17. The airbag module of claim 7, wherein the edge sections of the insertion opening are arranged and positioned to symmetrically mirror one another.

18. The airbag module of claim 7, wherein each of the clips is formed in one piece woven structure with the associated airbag part.

19. The airbag module claim 7, wherein the airbag parts are connected to one another outside the insertion opening.

20. The airbag module of claim 19, wherein the airbag parts are connected to one another outside the insertion opening, at least in certain sections, by sewing, bonding or riveting.

21. The airbag module of claim 7, wherein the two clips have at least one first mounting opening each, the mounting openings being embodied congruent with respect to one another in a spread out flat state of the airbag sleeve.

22. The airbag module of claim 7, wherein the two airbag parts have at least one second mounting opening each outside the clips, the mounting openings being embodied congruent with respect to one another in a spread out flat state of the airbag sleeve.
