Abstract

A pretensioner for a three point seat belt has a cylinder adapted to be attached to a structural member of a vehicle and a piston disposed within the cylinder. A pyrotechnic means (22) moves the piston in a direction that is longitudinal relative to the cylinder in a pretensioning direction (A). A slider bar (10) is oriented substantially parallel to a longitudinal axis of the cylinder. A seat belt webbing (14) is looped around the slider bar (10) such that the seat belt webbing can freely move along a portion of the slider bar that is oriented substantially parallel to a longitudinal axis of the cylinder so long as the pyrotechnic means for moving the piston has not been activated. A cable (20) extends from the piston and loops around the seat belt webbing (14) to cause the seat belt webbing to move along the slider bar (10) in a pretensioning direction (A) when the pyrotechnic means (22) for moving the piston is activated.
