Disclosed is an apparatus for adjusting the height of a seat, which comprises: a fixing member fixated on a seat cushion to have multiple first stoppers at a position on a certain radius from the center of an axial direction; an input member installed on a concentric axis with the fixing member to be able to rotate to have a hanging unit formed by protruding from the position on the radius facing the first stoppers; an output member which is installed on a concentric axis with the input member to be able to allow a relative rotation and has a friction flange unit protruding in the circumferential direction at a position on a certain radius facing the inner circumferential surface of the input member; and a friction rotating means installed to be able to rotate while being contracted in the circumferential direction in between the inner circumferential surface of the input member and the outer circumferential surface of the friction flange unit to be rotated by being pressed by the friction flange unit and being hung on the hanging unit when the input member rotates, to have the output member rotated together by having its relative rotation with the input member constrained, to be rotated by being released from pressing by the friction flange unit by being released from being hung on the hanging unit when the input member makes a returning rotation, and to allow relative rotation of the input member toward the output member.

    본 발명은, 시트쿠션에 고정 설치되며, 축방향 중심으로부터 일정 반경 위치에 복수의 제1스토퍼가 형성된 고정부재; 상기 고정부재와 동심축 상에서 회전 가능하게 설치되며, 상기 제1스토퍼와 마주하는 반경 위치에 걸림부가 돌출되어 형성된 입력부재; 상기 입력부재에 대해 동심축 상에서 상대 회전 가능하게 설치되며, 상기 입력부재의 내주면과 마주하는 일정 반경 위치에 원주방향을 따라 마찰플랜지부가 돌출되어 형성된 출력부재; 및 상기 입력부재의 내주면과 마찰플랜지부의 외주면 사이에서 원주방향을 따라 신축되면서 회전 가능하게 설치되며, 상기 입력부재의 회전시 상기 걸림부에 걸려져 마찰플랜지부에 압입된 상태로 회전됨으로써 상기 출력부재가 입력부재와의 상대 회전이 구속된 상태로 함께 회전되고, 상기 입력부재의 복귀 회전시 상기 걸림부로부터 걸림 해제되어 마찰플랜지부에 압입 해제된 상태로 회전됨으로써 상기 출력부재에 대해 입력부재가 상대 회전되도록 구성된 마찰회전수단;을 포함하여 구성되는 시트용 높이 조절장치가 소개된다.
