Abstract: An actuatable fastener (50) includes a body (80) including a head (82) and a shank (84). The body (80) includes an interior chamber (120) partially defined by a side wall (132) extending from the head (82) into the shank (84) and an end wall (138) positioned in the shank. A member (140) is disposed in the chamber (120). An initiator (160) is actuatable to produce combustion products in the chamber (120) that act on the member (140) to move the member in a first direction in the chamber to strike the end wall (138). The member (140) strikes the end wall (138) creating a fracture (222) in the shank (84) separating at least a portion of the shank from a remainder (220) of the shank. The combustion products moving the member (150) beyond the fracture (222) at least a predetermined distance (226) to move the portion of the shank (84) at least the predetermined distance from the remainder (220) of the shank.

Abstract: A vehicle occupant protection apparatus (10) includes an inflatable occupant protection device (18) and a member (20) that defines a deployment opening (22) through which the inflatable occupant protection device (18) is inflatable. The vehicle occupant protection apparatus (10) also includes a cover (30) having an attachment portion (34) and a deployment door portion (36). The attachment portion (34) is securable to the member (20) for positioning the deployment door portion (36) for closing the deployment opening (22). The cover (30) also includes a rupturable portion (134, 136, and 156) that ruptures for enabling inflation of the inflatable occupant protection device (18) through the deployment opening (22). At least a part of the rupturable portion (134, 136, and 156) is formed at a union of the attachment portion (34) and the deployment door portion (36).
