A power seat adjuster includes a rotatable drive shaft with first and second axial ends and an intermediate arcuate portion connecting the first and second axial ends. The first and second axial ends are respectively axially connected to a drive motor gear assembly and to a driven lead screw. A horizontal drive block threadingly engaging the lead screw is rotatably and vertically translatingly mounted in an aperture in a lower track for self-alignment of the drive block with respect to the lead screw. A housing rotatably receives the axial connection between one end of the drive shaft and the lead screw. The bearing block is rotatably and translatingly mounted in a bracket fixed to an upper track for self-alignment of the drive shaft with the lead screw. A drive block engages the lead screw and is mounted for rotation and translation in a link. The upper and lower tracks have a guide section and an abutment section which collapse together in a self-cinching action under force loading to resist separation of the upper and lower tracks.
