An actuatable fastener () includes a body () including a head () and a shank (). The body () includes an interior chamber () partially defined by a side wall () extending from the head () into the shank () and an end wall () positioned in the shank. A member () is disposed in the chamber (). An initiator () is actuatable to produce combustion products in the chamber () that act on the member () to move the member in a first direction in the chamber to strike the end wall (). The member () strikes the end wall () creating a fracture () in the shank () separating at least a portion of the shank from a remainder () of the shank. The combustion products moving the member () beyond the fracture () at least a predetermined distance () to move the portion of the shank () at least the predetermined distance from the remainder () of the shank.

An apparatus (10) for inflating an inflatable vehicle occupant protection device (40) includes a housing (12) and a container (50) mounted in the housing. A quantity of helium gas (52) is stored under pressure in the container (50). The apparatus (10) includes means (58) for opening the container (50) to enable flow of helium gas (52) out of the container into the housing (12). The housing (12) has wall portions (14, 16, 18, 20) for directing helium gas (52) flowing from the container (50) through an outlet (26) of the housing into the inflatable device (40) to inflate the inflatable device. The housing (12) has at least one aspiration opening (30, 32) for aspirating ambient air into the housing due to the flow of helium gas (52) to mix with the helium gas during flow of helium gas from the container (50) into the inflatable device (40). Preferably, the apparatus (10) includes a converging-diverging nozzle (70) which is connected with the container (50) and through which gas (52) flows from the container prior to mixing with ambient air in the housing (12).
