First Claim
1. An airbag module for a motor vehicle, comprising:
- an airbag that can be inflated in order to protect a person,the airbag forming a covering that defines an interior space that can be filled with gas for inflating the airbag,a gas generator for providing the gas needed for inflating the airbag,an insertion opening of the airbag covering, wherein the gas generator is inserted through the insertion opening into the interior space of the airbag, so that gas provided by the gas generator can get into the interior space of the airbag,a boundary region of the insertion opening delimiting the insertion opening, the boundary region annularly encompassing the gas generator, anda sealing means for sealing the insertion opening,wherein the sealing means is arranged between the boundary region and the gas generator in a way that the sealing means is widened by means of the gas provided by the gas generator and pressed against the boundary region of the insertion opening for sealing the insertion opening, wherein the sealing means is pressed with a middle portion circulating the gas generator against the boundary region of the insertion opening.

Abstract
An airbag module including an airbag, an airbag covering, that defines an interior space of the airbag, that can be filled with gas for inflating the airbag, a gas generator for providing the gas needed for inflating the airbag, an insertion opening of the airbag covering, wherein the gas generator is inserted through the insertion opening into the interior space of the airbag, so that gas provided by the gas generator enters the interior space of the airbag, a boundary region of the insertion opening delimiting the insertion opening, which boundary region annularly encompasses the gas generator, and a sealing means for sealing the insertion opening. The sealing means is arranged between the boundary region and the gas generator so that the sealing means is widened by the gas provided by the gas generator and pressed against the boundary region of the insertion opening for sealing the insertion opening.

15. A method for producing an airbag, comprising the steps of:
-
providing an airbag, the airbag forming a covering that defines an interior space of the airbag that can be filled with gas for inflating the airbag; inserting a sealing means into the insertion opening so that a boundary region of the insertion opening delimiting the insertion opening annularly encompasses a circumferential middle portion of the sealing means that forms a receptacle for the gas generator; and inserting the gas generator into the receptacle of the sealing means, such that gas that is to be provided by the gas generator can get into the interior space of the airbag and can widen the middle portion and press it against the boundary region of the insertion opening.
