Abstract: A vibration attenuation apparatus may include a mass element, a bracket, and an elastomeric member. The mass element may include a first aperture. The bracket may include first and second portions. The first portion may be attached to a structure that transmits an input vibration. The elastomeric member may engage the mass element and the second portion of the bracket and may suspend the mass element relative to the bracket. The elastomeric member may include a shaft portion and a barb portion. The shaft portion may engage the second portion of the bracket. The barb portion may engage the first aperture of the mass element. The elastomeric member may include properties allowing the mass element to move relative to the bracket in response to the input vibration at a frequency that reduces an amplitude of the input vibration.

Abstract: An air bag module (20, 20a) comprising: an inflator (300), a first support member (200-200a), a second support member (250, 250a-250d) and a cover (30) for enclosing an air bag (100); the cover includes a plurality of resilient tabs (48), the tabs are situated in a predetermined pattern about a cavity (38) which receives the air bag (100), a formation having a thickened tip is formed on a distal end of each tab, the thickened tip is configured as lock feature (50) which prevents the cover from disengaging from the first and second support members, each tab and associated lock feature is movable from a rest position to a deflected position upon contact with one of the plates; the first and second support members are locatable about each tab and configured to cooperatively define an effective narrow opening which is of smaller dimension than the thick tip, thereby preventing movement of the thick tip through the first and second support members and hence the disengagement of the cover from the first and second
