1. An airbag module comprisingan airbag holder having a base body and a projection formed on a peripheral surface of the base body;
- said projection having a first side and a second side and further comprising a cut-out extending from the first side to the second side, andan airbag comprising an airbag mouth having a peripheral contour smaller than the projection and engaging the base body adjacent the first side of the projection;
wherein the cut-out is sized and shaped to receive an introduction section of the airbag mouth such that first section of the airbag mouth adjoining the introduction section is arranged on the first side of the projection and a second section of the airbag mouth is arranged on the second side of the projection and further such that rotational movement of the airbag mouth relative to the base body passes the second section of the airbag mouth through the cut-out into position on the first side of the projection, whereupon both the first section and the second section of the airbag mouth are disposed adjacent the first side of the projection.

Abstract
An airbag module includes an airbag holder, which has a base body and a projection on a peripheral surface of the base body extending around this in full or with the exception of at least one interruption, and an airbag which has an airbag mouth whose peripheral contour is smaller than a peripheral contour enclosing the projection and the base body and which is held at the airbag holder in an end position in which the airbag mouth encloses the base body and thereby engages behind the projection at a first side of the projection.

11. A method for the attachment of an airbag to an airbag holder, said method comprising
providing an airbag having an airbag mouth; -
providing an airbag holder comprising a base body and a projection formed at a peripheral surface of the base body, said projection comprising a first side and a second side and further comprising a cut-out extending from the first side to the second side, introducing an introduction section of the airbag mouth into the cut-out such that a first section of the airbag mouth is adjacent the first side of the projection and a second section of the airbag mouth is adjacent the second side of the projection; and moving the airbag mouth rotationally relative to the base body to pass the second side through the cut-out to the first side, such that both the first section and the second section engage the base body adjacent the first side of the projection.
