Abstract
A gas inflator is movably supported in a spacer pot and/or in a protective sleeve of an airbag housing, and functions as a vibration damper weight. An annular spring element made of polymer material that is impermeable to gas is joined to the gas inflator's outer wall and to a supporting plate. A vacant vibration space is formed for the vibration damper weight between the gas inflator and the interior wall of the spacer pot or protective sleeve. The spring element is provided with a plurality of elastic projections that are distributed on the exterior periphery of the spring element. The projections cause a defined deceleration of the vibration weight in response to the traversing of the vacant vibration space.
