ABSTRACT:
A housing has a chamber and a piston is slidablyally mounted in the chamber. The piston has a piston shaft which extends outwardly of the housing and has a seat belt reel attached thereto. A pyrotechnic device is energizable to introduce pressurized gas into the chamber and thereby translate the piston within the chamber. Screw threads are provided between the housing and the piston shaft so that translation of the piston shaft upon energization of the pyrotechnic device will cause the screws to impart rotation to the piston shaft and the seat reel. Accordingly, the seat belt reel is simultaneously rotated to wind the belt and also projected outwardly with respect to the housing so that the belt is tensioned by both a rotary and a projecting action of the seat belt reel.
