Befestigungsvorrichtung der Abdeckplatte einer Luftsackeinrichtung

A monolithic cover (20) for a vehicle safety airbag module includes a front face (42) from which a skirt (52) depends at a lower end of which resilient flaps (58) having tapered foot extensions (80) are formed. Tapered ribs (84) and flap ribs (82) on exterior surfaces of the skirt (52) and flaps (58) respectively stiffen these parts. A circular inflator (12) with an annular flange (28) to which an annular support plate (60) is bolted is connected to the cover (20) by snapping the flaps (58) over the support plate (60) so that the support plate is held between a lower free edge (56) of the skirt (52) and shoulders (70) formed on upper surfaces of the foot extensions (80). A retaining plate (62) is bolted against the tapered flap ribs (82) to prevent outward movement of the flaps (58) and inadvertent cover release upon airbag deployment.
