Abstract
Disclosed is a pretensioner for an occupant restraint. The pretensioner is designed to be used in conjunction with an inertial reel that locks the occupant restraint when detecting an adverse event. The pretensioner acts to remove slack in the webbing of the restraint and thereby safely secure the occupant once the reel is locked. The pretensioner described herein includes a rack that is initially held in place by a shear pin. Upon being activated, the rack is forced to a fully extended orientation, whereby the shear pin is severed. A deceleration ramp in included beneath the rack to slowly bring the rack to a stop at the end of the stroke.
