Abstract

본 발명은 체형에 맞도록 형태변화가 가능한 시트에 관한 것으로, 등받이(20)와 좌대(30)로 구성된 자동차용 시트(10)에 있어서, 상기 등받이(20)의 내부에 고정. 설치된 프레임(50)과, 좌대(30)의 내부에 설치된 기어(40)와 맞물리도록 등받이(20)의 내부 양측에 구비된 제1기어(60)와, 이 제1기어(60)와 맞물리도록 양측으로 형성된 제2기어(70)와, 제2기어(70)의 사이에 형성된 제3기어(80)와, 이 제3기어(80)와 프레임(50)의 상부쪽에 소정의 간격을 두고 마주보도록 설치된 제4기어(82)와, 상기 제3, 4기어(80, 82)의 외주면에 감싸져 소정의 텐션을 가지도록 설치된 타이밍벨트(90)와, 이 타이밍벨트(90)의 일측에 설치되어 타이밍벨트(90)와 일체로 이동가능하도록 상기 프레임(50)을 관통하여 설치된 슬라이더(100)와, 상기 슬라이더(100)와 일체로 이동되도록, 웨이브형태를 이루면서 탄지된 다수개의 스프링(110)으로 구성된 것으로, 사용자가 시트(10)의 등받이(20)를 세우거나 젖히더라도 사용자의 등을 보다 확실하게 지지하여 쾌적한 느낌을 줄 수 있도록 한 것이다.The present invention relates to a seat that can be changed in shape to fit the body shape, in the automobile seat (10) consisting of a backrest (20) and a seat (30), fixed to the inside of the backrest (20). A first gear 60 provided on both sides of the backrest 20 so as to mesh with the installed frame 50 and the gear 40 provided inside the pedestal 30, and to mesh with the first gear 60; The second gear 70 formed on both sides and the third gear 80 formed between the second gear 70 face each other at a predetermined interval on the upper side of the third gear 80 and the frame 50. A fourth gear 82 provided to be seen, a timing belt 90 provided to be wrapped around the outer circumferential surfaces of the third and fourth gears 80 and 82 to have a predetermined tension, and installed on one side of the timing belt 90. And a slider 100 installed through the frame 50 to be integrally movable with the timing belt 90, and a plurality of springs 110 supported in a wave form to move integrally with the slider 100. It is configured to, even if the user raises or lowers the backrest 20 of the seat 10 to support the user's back more reliably and comfortable It is to give a feeling.
