Abstract
A load limiting device for mounting a seat belt buckle includes a plow shoe attached to one of the buckle and the vehicle and a pair of opposed plates attached to the other of the buckle and the vehicle. The plates have the plow shoe captured therebetween so that upon imposition of an occupant restraint load on the buckle, the plow shoe travels therebetween the plates and absorbs energy by deforming at least one of the plates. An adjuster mechanism adjusts the distance between the opposed plates to selectively increase or decrease the energy absorbing capacity of the load limiting device by determining the extent of metal deformation occurring upon the travel of the plow shoe.
