Abstract

본 발명은 허리 지지대의 전후 위치에 대한 미세 조정이 가능할 뿐만아니라, 구조가 간단하여 제조가 용이하며 저중량의 자동차 시트의 등받이에 설치되는 허리 지지대로서, 자동차의 시트 등받이의 양측부에 설치되는 한쌍의 측부 프레임과; 측부 프레임의 하나를 관통하는 축을 가지는 회전손잡이와; 상기 측부 프레임의 내측에 위치되는 회전 손잡이의 축에 설치되는 기어와; 상기 한쌍의 프레임의 내측에 위치되어 각각 제1핀에 의하여 프레임에 대해 선회할수 있도록 설치되며, 한쪽의 하부에는 장공이 형성되며, 막대 형상의 허리 지지대 및 인장 스프링에 의하여 연결되는 한 쌍의 허리 지지대 프레임과; 기어와 결합하는 기어부가 상부에 형성되며, 측부 프레임의 하나에 설치된 제2핀이 결합하는 구멍이 형성되어, 기어의 회전으로 상기 제2핀을 중심으로 선회하며, 하부에는 장공 내에 위치되어, 선회 운동시에 장공의 축면을 따라서 안내되는 제3핀이 설치되는 기어판을 포함한다.The present invention is not only capable of fine adjustment of the front and rear position of the waist support, but also easy to manufacture due to its simple structure and is a waist support installed on the backrest of a low-weight car seat, Side frames; A rotary knob having an axis penetrating one of the side frames; A gear installed on a shaft of a rotary knob located inside the side frame; Located inside the pair of frames, each of which is installed so as to pivot about the frame by a first pin, a lower hole is formed at one lower side thereof, and a pair of waist supports connected by a rod-shaped waist support and a tension spring. A frame; The gear part engaging with the gear is formed in the upper part, and a hole is formed in which the second pin installed in one of the side frames is engaged, turning around the second pin by the rotation of the gear, the lower part being located in the long hole, the turning And a gear plate on which a third pin is guided along the axial surface of the long hole during exercise.
