APPARATUS FOR MOVING MOTOR-OPERATED SEAT RAIL

摘要

An apparatus for moving a motor-operated seat rail, including a lead screw provided along an axial direction of a fixed rail, a mounting bracket having opposite ends combined with a moving rail, with the lead screw passing through a central portion of the mounting bracket so that the bracket moves along the lead screw, and a spindle nut engaged with the lead screw through a screw type engagement. A first end of the spindle nut is rotatably held on the mounting bracket so as to rotate relative to the bracket, and a second end passes through the central portion of the mounting bracket and extends along an axial direction of the lead screw, and being configured such that the inner diameter of the second end is able to be elastically reduced so that the inner circumferential surface of the second end comes into close contact with the outer circumferential surface of the lead screw.

主权项

1. An apparatus for moving a motor-operated seat rail having a moving rail and a fixed rail extending along an axial direction, the apparatus comprising:
a lead screw having a first outer circumferential surface; a mounting bracket having an outer surface and mounting opposite ends adapted to be combined with the moving rail, the lead screw passing through a central portion of the mounting bracket so that the mounting bracket moves along the lead screw; and a spindle nut engaged with the lead screw through a screw engagement and having a first end and a second end, the first end being rotatably held on the mounting bracket such that the first end rotates relative to the mounting bracket, the second end passing through the central portion of the mounting bracket and extending along the axial direction, the second end having a first inner circumferential surface defining an inner diameter being elastically reducible so that the first inner circumferential surface comes into close contact with the first outer circumferential surface of the lead screw.
