ABSTRACT:
An airbag assembly (10) includes a sheet metal door subassembly (36) with a cross cut (40) and two side cuts (38) that fully covers an airbag escape opening (34) in a primary substrate (32). The inflation of the airbag (16) causes two doors (42) of the subassembly 36, to bend around the primary substrate (32) at upper and lower sides of an airbag escape opening (34). A cutting edge (44) is located at one end (46) of one of the two doors (42) and cuts an opening through the outer uninterrupted cover (25) so the airbag (16) may expand therethrough into the passenger compartment of a vehicle. The subassembly (36) has a continuous periphery (36a) that is connected by a reduced number of rivets (26).
