ABSTRACT:
An adjustable vehicular seat assembly includes a fixed rail attached to the vehicle underbody and a sliding rail movably carried on the fixed rail. A six-way power seat adjustment mechanism is supported on the sliding rail and connects a seat frame thereto. A buckle for a seat belt harness is pivotally attached to the rearward end of the sliding rail and extends upwardly to a pivotal connection on the seat frame. The buckle includes a piston and hydraulic cylinder arrangement extendable and collapsible between the respective pivotal connections on the seat frame and the sliding rail for adjusting the distance between the two pivotal connections while the seat frame is articulated vertically by the power seat adjustment mechanism. The piston is carried on a piston rod integral with the buckle and includes a plurality of axially extending flow control orifices for restrictively conducting fluid flow while reciprocating within the hydraulic cylinder.
