The present invention provides a seat transport track for a vehicle, which includes a lower rail and an upper rail to move along the lower rail. The seat transport track for a vehicle comprises: a lower rail divided into a bottom unit extended in a width direction based on a cross section, a both side units bent upwards from both ends of the bottom unit, and a connection unit bent inwards from the both side units in the width direction and then bent downwards; an upper rail divided into an exposure unit extended in the width direction and bent downwards from both ends, and an insertion unit bent outwards from the exposure unit in the width direction and then bent upwards to allow a portion thereof to be inserted into the connection unit; a lower bearing ball which is seated on a portion bent from the bottom unit to the both side units, and supports the insertion unit; and an upper bearing ball arranged between a portion bent from the both side units to the connection unit and the insertion unit inserted into the connection unit. An angle formed by a first virtual line perpendicular to a tangent line of the lower rail and the lower bearing ball and a second virtual line perpendicular to a tangent line of the upper rail and the upper bearing ball is 80-100 degrees.

    로워레일과 로워레일을 따라 이동하는 어퍼레일로 구성된 차량용 시트이송트랙에 있어서, 단면을 기준으로 폭방향으로 연장된 바닥부와, 바닥부 양단에서 상방으로 절곡된 양측부와, 양측부에서 폭방향 내측으로 절곡되고 다시 하방으로 절곡된 연결부로 구분되는 로워레일; 폭방향으로 연장되다가 양단에서 하방으로 절곡된 노출부와, 노출부에서 폭방향 외측으로 절곡되고 다시 상방으로 절곡되어 일부가 연결부로 삽입되는 인입부로 구분되는 어퍼레일; 바닥부에서 양측부로 절곡되는 부분에 안착되며, 인입부를 지지하는 하부베어링볼; 및 양측부에서 연결부로 절곡되는 부분과 연결부로 삽입된 인입부 사이에 배치된 상부베어링볼;을 포함하고, 로워레일과 하부베어링볼의 접선에 수직인 가상의 제1선과 어퍼레일과 상부베어링볼의 접선에 수직인 가상의 제2선이 만나 형성하는 각도가 80~100°인 차량용 시트이송트랙이 소개된다.
