Abstract

An airbag module comprises a gas generator provided with an electrical connection and an airbag provided with a gas generator opening. The gas generator opening is used to introduce the gas from the gas generator into the airbag and can be sealed with at least one fabric element. The gas generator and the electrical connection are arranged in the region of the gas generator opening. The at least one fabric element is arranged and embodied in such a way that the gas generator opening is sealed by the at least one fabric element during and/or following the airbag deployment in the region of the gas generator and/or the on the electrical connection.

Claims

1. An airbag module, comprising:

a gas generator including an electrical connection;

an airbag including a gas generator opening for introducing the gas generator into the airbag, the gas generator opening positioned at a region of the gas generator such that prior to inflation the opening is over a section of the gas generator including an electrical connection; and

at least one fabric part, the gas generator opening being able to be sealed by the at least one fabric part,

wherein the gas generator and the electrical connection are arranged in a region of the gas generator opening, and the at least one fabric part is arranged such that sealing of the gas generator opening by the at least one fabric part occurs during and/or after the deployment of the airbag.

2. The airbag module as claimed in claim 1, wherein the gas generator is arranged, with the airbag folded, in the gas generator opening and a section of the gas generator protrudes out of the airbag,

wherein the electrical connection of the gas generator is provided on the protruding section of the gas generator, and

wherein the at least one fabric part covering the gas generator opening is configured such that the fabric part closes the gas generator opening during and/or after deployment of the airbag such that the gas generator lies entirely in the airbag.

3. The airbag module as claimed in claim 1, wherein the gas generator is arranged in the airbag directly behind the gas generator opening, and

wherein the electrical connection is guided out of the airbag through the gas generator opening.

4. The airbag module as claimed in claim 2, wherein the at least one fabric part covering the gas generator opening bears against the electrical connection during and/or after the deployment of the airbag.

5. The airbag module as claimed in claim 2, wherein the airbag in the region of the gas generator opening is configured such that an appliance connector of the electrical connection separates from the gas generator during deployment of the airbag, so that the at least one covering fabric part closes the airbag without a component situated in-between.

6. The airbag module as claimed in claim 5, wherein the appliance connector protrudes over a diameter of the gas generator, and

wherein the airbag includes an annular reinforcement in the region of the gas generator opening.

7. The airbag module as claimed in claim 2, wherein the airbag in the region of an appliance connector for connecting a connecting cable to the gas generator is configured such that the appliance connector of the electrical connection separates from the gas generator during deployment of the airbag, so that the at least one covering fabric part closes the airbag without a component situated in-between

8. The airbag module as claimed in claim 7, wherein the appliance connector protrudes over a diameter of the gas generator, and

wherein the airbag includes an annular reinforcement in the region of the gas generator opening.

9. The airbag module as claimed in claim 1, wherein two overlapping fabric parts cover the gas generator opening.

10. The airbag module as claimed in claim 1, wherein the gas generator comprises a tubular gas generator with the electrical connection on an end side of the tubular gas generator.

11. An airbag module, comprising:

a tubular gas generator including an electrical connection;

an airbag with a generator opening; and

at least one fabric part attached to the airbag,

wherein the gas generator is inserted into the airbag via the generator opening, and a portion of the gas generator protrudes out of the generator opening after installation of the gas generator and when the airbag is in a folded state, and

wherein the electrical connection protrudes out of the generator opening after installation of the gas generator and when the airbag is in the folded state, and during inflation of the airbag, the at least one fabric part seals the generator opening.

12. The airbag module as claimed in claim 11, wherein the electrical connection is provided on the protruding section of the gas generator.

13. The airbag module as claimed in claim 12, wherein the at least one fabric part covering the gas generator opening bears against the electrical connection during and/or after the deployment of the airbag.

14. The airbag module as claimed in claim 12, wherein the airbag in a region of the gas generator opening is configured such that an appliance connector of the electrical connection separates from the gas generator during deployment of the airbag, so that the at least one fabric part closes the airbag without a component situated in-between.

15. The airbag module as claimed in claim 14, wherein the appliance connector protrudes over a diameter of the gas generator, and

wherein the airbag includes an annular reinforcement in the region of the gas generator opening.

16. The airbag module as claimed in claim 12, wherein the airbag in the region of an appliance connector for connecting a connecting cable to the gas generator is configured such that the appliance connector of the electrical connection separates from the gas generator during deployment of the airbag, so that the at least one fabric part closes the airbag without a component situated in-between

17. The airbag module as claimed in claim 16, wherein the appliance connector protrudes over a diameter of the gas generator, and

wherein the airbag includes an annular reinforcement in the region of the gas generator opening.

18. The airbag module as claimed in claim 11, wherein two overlapping fabric parts cover the gas generator opening.
