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 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,

wherein the module is configured so that 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 wherein during inflation of the airbag, the portion of the gas generator is contained within the airbag and the at least one fabric part seals the generator, and

wherein the fabric part includes a sewn seam configured to attach at least a portion of a perimeter of the fabric part to the airbag around the generator opening, the fabric part including one side that is not attached via a sewn seam to the airbag and overlaps the airbag at the generator opening in the inflated state.

2. The airbag module as claimed in claim 1, wherein the electrical connection is provided on the protruding section of the gas generator.

3. 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.
