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 support members.
