Abstract
An elastic coupling device for elastically connecting a damping mass like a gas generator to a motor vehicle part exposed to oscillations and/or vibrations, in particular an airbag module, in one embodiment comprising a rigid support ring facing the vehicle, at least one fixation piece like a rivet head, the fixation piece facing the damping mass and being made of a rigid material, and a spring body coupling the support ring and the fixation piece. The support ring and/or the fixation piece, respectively made of a plastic material, as well as the spring body, which may be made of an elastomer material, may be produced in a single manufacturing step by means of a two-component process, in particular by two-component injection molding.
