Abstract

The invention relates to an airbag module (16) for an occupant restraint system, comprising a module cap (28) which in the mounted condition of the airbag module (16) faces an occupant and comprising a module bottom (30) which includes a latch means for securing the airbag module (16) to a vehicle component, wherein the module cap (28) and the module bottom (30) are movable toward each other along a mounting axis (A) until they reach at first an axial pre-mounting position and then an axial final mounting position, the module cap (28) and the module bottom (30) including interacting pre-fixing elements which captively secure the module cap (28) and the module bottom (30) to each other in the pre-mounting position, the module cap (28) and the module bottom (30) including interacting resistance contours which during an axial relative movement of the module cap (28) and the module bottom (30) from the pre-mounting position to the final mounting position have a predetermined mounting resistance. Furthermore, the invention also relates to a method for mounting the airbag module (16) on a steering wheel as well as to a steering assembly (10) comprising such airbag module (16).
