1. An airbag module assembly for mounting on a steering wheel main part, comprising:
a driver's airbag module comprising a folded airbag, a gas generator for inflating the folded airbag and a module housing for receiving the gas generator and the folded airbag;
a steering wheel mounting plate configured to be mounted rigidly to the steering wheel main part; and
a vibration absorber unit configured to support the driver's airbag module on the steering wheel mounting plate,
wherein the module housing is positioned over the steering wheel mounting plate and is secured to the steering wheel mounting plate via the vibration absorber unit, and
wherein the vibration absorber unit comprises a connector and a resilient damping element through which the connector extends, the connector being connected to structure that supports the housing of the driver's airbag module substantially without play and in a non-displaceable manner;
the resilient damping element extending through the steering wheel mounting plate and receiving a portion of the steering wheel mounting plate to connect the resilient damping element to the steering wheel mounting plate, wherein the resilient damping element has one end that engages the structure that supports the housing of the driver's airbag module substantially without play and in a non-displaceable manner, and an opposite end that engages the vibration absorber unit, the resilient damping element isolating the steering wheel mounting plate from the structure that supports the housing of the driver's airbag module so that the driver's airbag module can vibrate relative to the steering wheel mounting plate and the steering wheel main part.
