Abstract: An airbag module having an airbag casing and at least one installation opening (1) formed in the airbag casing for guiding in at least one part of a gas generator. The airbag casing has at least two layers (2) regionally lying one another, in which differently-oriented incisions are provided that together form the installation opening (1). The layers (2) lying over one another forming the installation opening (1) are connected to one another by at least one seam (5). The region (4) of the airbag casing forming the installation openings (1) is separated from the rest of the airbag casing by the seam. The incisions in each layer (2) each form a longitudinal recess (3) forming a combined shape with an outer circumferential line in their projection viewed over all layers (2) and the seam duplicates the circumferential line of the combined shape.
