ABSTRACT:
An inflatable vehicle occupant restraint (18) has a stored condition and an inflated vehicle occupant restraining position. A support member (16) at least in part defines an opening (19) through which the vehicle occupant restraint (18) is deployed when inflated. A deployment door member (12) closes the opening (19). The support member (16) supports the deployment door member (12) at a first side of the opening (19) for pivotal movement relative to the support member upon inflation of the vehicle occupant restraint (18). The deployment door member (12) has a plurality of slots (95). The support member (16) includes a plurality of shear tabs (54) located at a second side of the opening (19) opposite the first side. Each shear tab (54) extends through a respective one of the slots (95) in the deployment door member (12). Each shear tab (54) shears through the material of the deployment door member (12) as the deployment door member pivots relative to the support member (16) upon inflation of the vehicle occupant restraint (18) to release the deployment door member at the second side of the opening (19) from the support member.
