Abstract: A linear pretensioner for use as part of a motor vehicle occupant belt restraint system mountable to vehicle structure and coupled with a belt restraint system component. The pretensioner includes at least one base plate having a slot and at least one closure plate fixedly attached to the base plate. The closure plate(s) and the slot of the base plate(s) form a cavity having an open end. A piston plate has a piston tail slidably disposed within the cavity and a piston head extending from the open end. A cable is coupled with the piston plate, the base plate(s), and/or the closure plate(s). The piston plate, the slot of the base plate(s), and the closure plate(s) cooperate to form an expanding chamber that enlarges when pressurized by a gas generator, which drives the piston plate and the base plate relative to each other to exert tension on the cable.

Abstract: A linear pretensioner device for motor vehicle belt restraint systems of the type mountable to a motor vehicle structure and coupled with a belt restraint system component. In one form, the linear pretensioner includes a stroking housing forming a bore and a cable coupled with the stroking housing and to the belt restraint component. A main housing adapted to be fixed to the motor vehicle structure is positioned within the bore of the stroking housing, with the stroking housing telescopically overfitting the main housing. The main housing and the stroking housing form an expanding chamber that enlarges when pressurized by a gas generator. Upon activation, the gas generator drives the stroking housing along the main housing to exert tension on the cable. In another form, the pretensioner has an inner housing positioned within a bore of an outer housing, and the cable is coupled with the inner housing.
