An adjustment assembly for adjusting the height of a vehicle seat includes an inboard track assembly, an outboard track assembly spaced apart from the inboard track assembly, and at least one torque tube extending between the assemblies. The inboard and outboard track assemblies each have a first track fixed to a vehicle structure and a second track supported for longitudinal movement with respect to the first track to adjust horizontal seat position. A seat bottom mounted for horizontal movement with the second track. The torque tube is interconnected to the seat member by a linkage assembly to move the seat member between a lowered position and a raised position. An actuator is selectively actuated to supply rotational input to the torque tube. As the torque tube rotates, the linkage assembly moves the seat bottom in a vertical direction. The adjustment assembly includes at least one stop supported on one of the inboard or outboard track assemblies. A link member, controlled by movement of the torque tube, engages the stop to define maximum raised and lowered seat bottom positions.
