ABSTRACT:
A seat assembly is disclosed with an articulating seat cushion rotatable about a transverse axis near the front end of the seat cushion. The seat back is reclinable and is coupled to the rear of the seat cushion so as to raise the rear end of the seat cushion in response to rearward reclining of the seat back whereby the seat occupant's hip point is raised as the seat back is reclined to provide a more comfortable recliner. The recliner drive mechanism includes a lead screw with a motor/transmission assembly to drive the lead screw and includes a thrust washer carried by the lead screw to transfer axial loads on the lead screw directly to the motor mount rather than allowing the lead screw loads to be transferred to the internal components of the motor/transmission assembly.
