Abstract
The invention relates to an airbag module (10) for a vehicle steering wheel (6), comprising a module base (12) for fixed mounting on the vehicle steering wheel (6), which module base has a base opening (14), and a vibration absorber ring (16) for fastening a gas generator (18) to the module base (12) such that said gas generator can vibrate. The vibration absorber ring (16) has a ring axis (A) and a mounting flange (20) for the gas generator (18). The vibration absorber ring (16) has a resilient absorber wall (22), starting from the mounting flange (20), which absorber wall extends in an axial direction toward the module base (12) and extends around the ring axis (A) in the circumferential direction. The vibration absorber ring (16) has a plurality of resilient absorber feet (24) for fastening to the module base (12), which absorber feet extend in the axial direction. The vibration absorber ring (16) is fastened to the module base (12) by means of the absorber feet (24) such that the absorber wall (22) bears against the module base (12) already before activation of the airbag module (10) and acts in an axial direction against the module base (12) and is resiliently deformed.
