Abstract
The invention relates to an apparatus (10) for fastening a gas generator (11) in an oscillatory manner as a vibration damping mass inside an airbag module. A fastening ring (12) provided for fastening the gas generator (11) has at least one elastic section (14) and at least one reinforcement insert (15) for reinforcing the fastening ring (12) and securing the fastening ring (12) to the gas generator. A surface of the reinforcement insert (15) is made at least in part of plastic.
Claims24
An apparatus (10) for fastening a gas generator (11) in an oscillatory manner as a vibration damping mass inside an airbag module, comprising a fastening ring (12) for engaging an annular flange (16) of the gas generator (11) to fasten the gas generator (11), the fastening ring (12) having at least one elastic section (14) and at least one reinforcement insert (15) for reinforcing the fastening ring (12) and for securing the fastening ring (12) to the gas generator (11), the at least one elastic section (14) being separate from the at least one reinforcement insert (15);
- wherein the flange (16) extends outwardly from an outer wall of the gas generator (11) and includes at least one bent portion which connects a straight portion of the flange (16) to the outer wall, the straight portion of the flange (16) having an annular lower surface;
- wherein a surface of the at least one reinforcement insert (15) is made at least in part of plastic, the at least one elastic section (14) being adhered to the plastic part of the at least one reinforcement insert (15);
- wherein the elastic section (14) and the reinforcement insert (15) define an annular upper surface of the fastening ring (12) that is configured to directly engage the annular lower surface of the straight portion of the flange (16) when the fastening ring (12) is secured to the gas generator (11) so that the lower surface of the straight portion of the flange (16) is seated directly on both the elastic section (14) and the reinforcement insert (15).
An apparatus (10) for fastening a gas generator (11) in an oscillatory manner as a vibration damping mass inside an airbag module, comprising:
- a fastening ring (12) provided for fastening the gas generator (11), the fastening ring (12) having at least one elastic section (14), the at least one elastic section (14) being formed by an annular elastic element (26), the annular elastic element (26) including a plurality of damping members (13) axially extending from an annular lower surface of the annular elastic element (26), the damping members (13) being configured to be fastened to a generator support in a mounted state of the airbag module, and
- a reinforcing member (25) for reinforcing the fastening ring (12) and securing the fastening ring (12) to the gas generator (11), the reinforcing member (25) being separate from both the at least one elastic section (14) and the generator support, the reinforcing member (25) having a plurality of axially extending openings configured to axially receive the damping members (13), the reinforcing member (25) at least in portions circumferentially surrounding an outer peripheral area (28) of the annular elastic element (26) such that the elastic section (14) can be secured to the gas generator (11).
An apparatus (10) for fastening a gas generator (11) in an oscillatory manner as a vibration damping mass inside an airbag module, comprising a fastening ring (12) for fastening the gas generator (11), the fastening ring (12) having at least one elastic section (14) and at least one reinforcement insert (15) for reinforcing the fastening ring (12) and for securing the fastening ring (12) to the gas generator (11), the at least one elastic section (14) being separate from the at least one reinforcement insert (15);
- wherein the at least one reinforcement insert (15) is formed from a metal core that has portions coated and/or over-molded with plastic, the reinforcement insert (15) having at least one fastening portion comprised of plastic-free portions of the metal core that are plastically deformable to secure the fastening ring (12) to the gas generator (11);
- wherein the at least one elastic section (14) is adhered to the plastic portions of the reinforcement insert (15);
- and
- wherein the elastic section (14) and the reinforcement insert (15) are in direct contact with a flange (16) of the gas generator (11) when the fastening ring (12) is secured to the gas generator (11).
