Abstract:

A linear actuator with an internal dampening mechanism is disclosed. The actuator has a housing has a first end and a second end and forms an internal chamber. A constricted opening is also added to the actuator at the first end. A piston is disposed within the housing and is capable of sliding along the chamber. The piston has a head portion and a shaft portion. The shaft portion is slidable through the constricted opening whereas the head portion is not slidable through the constricted opening. A fluid is also added to the actuator. The fluid is disposed within the housing. In one embodiment, the actuator is constructed such that the sliding of the shaft portion forces a fluid through the constricted opening such that the movement of the piston is dampened. In an alternative embodiment, the actuator includes one or more second pistons and an orifice. In this embodiment, the actuator is constructed such that the sliding of the piston forces the fluid through the orifice and causes the second pistons to telescopically extend from the first piston.

Abstract:

A wrapped gas generant cartridge is incorporated in an inflator of a vehicle occupant restraint system. The gas generant cartridge includes a stacked, aligned plurality of substantially flat annular wafers of gas generant material having a central opening therethrough. A wrap of sheet material surrounds the plurality of wafers and has marginal end panels folded along the end surfaces of the plurality of wafers, leaving at least one end opening exposed for receiving an ignition tube of the inflator. The wrap of sheet material is selected from metal foil, expanded metal, cellulose, thermoplastics, including polyolefin shrink wrap, with tape, adhesive or adhesive laminates holding the wrap in position. The gas generant cartridge is received in a filter and screen pack within the inflator.
