상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.

도 1 은 본 발명 자동차시트용 등받이 폴딩장치의 측면도이고, 도 2 는 본 발명 자동차시트용 등받이 폴딩장치의 또다른 측면도이며, 도 3 은 본 발명 자동차시트용 등받이 폴딩장치의 동작도로서,1 is a side view of the backrest folding device for a car seat of the present invention, Figure 2 is another side view of the backrest folding device for a car seat of the present invention, Figure 3 is an operation of the backrest folding device for a car seat of the present invention,

본 발명은 자동차 시트 등받이 취부 프레임(10) 측면에 구비된 작동레버(1)를 당기면 상기 작동레버(1)의 일측면에 핀으로 체결 결합된 캠(2)이 회전하고, 상기 록기어(3)의 끝단이 작동레버(1)의 가이드홈을 따라 회전하여 록(lock)이 해제되며, 상기 록기어(3)의 기어측과 맞물려 치합된 섹터기어(4)가 회동하는 것은 종래의 기술과 동일한 구조를 가진다.(도3)According to the present invention, when the operation lever 1 provided on the side of the vehicle seat back mounting frame 10 is pulled, the cam 2 fastened and coupled to one side of the operation lever 1 rotates, and the lock gear 3 End is rotated along the guide groove of the actuating lever 1 so that the lock is released and the sector gear 4 engaged with the gear side of the lock gear 3 is rotated. It has the same structure (Fig. 3).

그러나 본 발명은 상기와 같이 구성 동작하는 섹터기어(4) 상측면에 도 1 에 도시된 바와 같이 스파이럴 스프링(5)이 메인샤프트(6)로 체결 결합되어 구성된다.However, in the present invention, the spiral spring 5 is fastened and coupled to the main shaft 6, as shown in FIG. 1, on the upper side of the sector gear 4 operating as described above.

그리고, 상기 스파이럴 스프링(5)과 메인샤프트(6)는 캐치플레이트(7)로 고정설치되고, 상기 스파이럴 스프링(5) 끝단은 시트등받이 프레임의 일측면에 구비된 후크(8)에 걸리도록 구성된다.In addition, the spiral spring 5 and the main shaft 6 is fixed to the catch plate 7, the end of the spiral spring 5 is configured to be hooked to the hook 8 provided on one side of the seat back frame do.

한편, 시트 등받이 취부 프레임의 또다른 일측면에 구비된 스파이럴 스프링(5)의 감긴 방향은 또다른 일측면에 감긴 스파이럴 스프링(5)의 방향과 반대방향으로 감겨져 구성된다.On the other hand, the winding direction of the spiral spring (5) provided on another side of the seat back mounting frame is wound in a direction opposite to the direction of the spiral spring (5) wound on another one side.

상기와 같이 구성된 본 발명은 폴딩(folding)시 레버(1)를 당겨 록기어(3)가 해제되면, 섹터기어(4)가 회전하여 폴딩을 하게되는데 시트등받이 취부 프레임(10)의 양측면에 서로 다른방향으로 감기고 끝단이 후크(8)에 걸리도록 장착된 스파이럴 스프링(5)의 이완과 풀림에 의해 시트 등받이가 급속으로 접히는 것이 방지된다.According to the present invention configured as described above, when the lock gear 3 is released by pulling the lever 1 during folding, the sector gear 4 is rotated to be folded, but the two sides of the seat back mounting frame 10 are folded together. The seat back is prevented from being folded rapidly by the loosening and unwinding of the spiral spring 5 which is wound in the other direction and is mounted such that the end is caught by the hook 8.
