Abstract:
A gas inflator for an airbag on a motor vehicle steering wheel, comprising:a gas inflator movably supported in a spacer pot or in a protective sleeve of an airbag housing so that it functions as a vibration damper weight, a vacant vibration space being formed between the gas inflator and an interior wall of the spacer pot or protective sleeve; an annular spring element made of a polymer material that is impermeable to gas, said annular spring element being connected to an outer wall of the gas inflator and to a supporting plate; and a plurality of individual projections circumferentially distributed on the exterior circumference of the annular spring element, the projections each having at least one lip-shaped or truncated cone-shaped protuberance and causing a defined deceleration of the vibration damper weight in response to the traversing of the vacant vibration space to dampen impact.
