<p>A vehicle seat assembly (10) includes a seat bottom (12) and a seat back (14) supported for movement relative to the seat bottom such that seat position can be adjusted forwardly or rearwardly with respect to the vehicle. The seat assembly is mounted to a vehicle structure (20) and includes a first track (18) and a second track (22) supported for movement relative to the first track with the seat bottom being supported on the second track for movement with the second track. An actuator selectively controls the movement of the second track with respect to the first track. The assembly also includes at least one torque tube (34) for providing vertical seat adjustment. The torque tube presents a bearing surface for rotatably supporting a bearing surface located on the second track.</p> |
