Abstract

An assembly consists of a car body, a windshield, a dashboard with an air vent for providing an air flow to the windshield, and an airbag module. The airbag module is arranged between the windshield and the air vent.

Claims

1. An assembly consisting of a car body, a windshield, a dashboard with an air vent for providing an air flow to said windshield, and an airbag module, said airbag module being arranged between said windshield and said air vent.

2. The assembly according to claim 1, wherein said airbag module comprises an airbag that is folded into an airbag package, and wherein an ejection channel is provided for ejecting said airbag, said ejection channel opening up into an ejection opening through which said airbag can be ejected.

3. The assembly according to claim 2, wherein said airbag module comprises a housing and said ejection channel is limited by a first ejection channel wall that is formed by said housing and by a second ejection channel wall that is formed by said car body.

4. The assembly according to claim 3, wherein said car body comprises a windshield holder for said windshield, said second ejection channel wall being formed by said windshield holder.

5. The assembly according to claim 3, wherein said car body has a splashboard, said second ejection channel wall being formed by said splashboard.

6. The assembly according to claim 2, wherein said airbag module has a gas lance through which a gas can be fed into said airbag.

7. The assembly according to claim 6, wherein said gas lance has a middle as well as ends and is provided with gill-shaped outflow openings.

8. The assembly according to claim 7, wherein said gill-shaped outflow openings are aligned in such a way that said gas flowing out of said gas lance flows towards said ends of said gas lance.

9. The assembly according to claim 7, wherein said gill-shaped outflow openings are aligned in such a way that said gas flowing out of said gas lance flows towards said middle of said gas lance.

10. The assembly according to claim 7, wherein said gill-shaped outflow openings are aligned in such a way that said gas flowing out of said gas lance is swirled up.

11. The assembly according to claim 6, wherein said gas lance is located between said airbag package and said air vent.

12. The assembly according to claim 6, wherein said gas lance is located between said airbag package and said windshield.

13. The assembly according to claim 6, wherein said airbag package comprises first and second partial packages, of which said first partial package is folded in a first manner and is situated closer to said ejection opening, whereas

said second partial package is folded in a second manner and is arranged further away from said ejection opening.

14. The assembly according to claim 13, wherein said first partial package is located between said ejection opening and said gas lance.

15. The assembly according to claim 2, wherein said ejection channel is positioned to be angled with respect to said housing such that it runs parallel to said windshield.

16. The assembly according to claim 1, wherein said airbag module has separate gas generators for a driver side and a passenger side.

17. The assembly according to claim 1, wherein said airbag module has a shared gas generator for a driver side and a passenger side.

18. The assembly according to claim 1, wherein said housing is arranged on said air vent.

19. The assembly according to claim 18, wherein said housing is formed in one piece with said air vent.

20. The assembly according to claim 18, wherein said housing is screwed to said air vent.

21. The assembly according to claim 1, wherein a transition pipe is arranged between said gas lance and said gas generator.

22. The assembly according to claim 6, wherein said gas lance is provided with protrusions in which said gas bag is hung in.

23. The assembly according to claim 1, wherein a T-piece is arranged on said gas generator, said T-piece at the same time serving as a holder for a bursting membrane.

24. The assembly according to claim 1, wherein a T-piece is provided which is crimped with said gas generator.
