상기와 같은 본 발명의 리클라이닝장치(100)의 작동관계를 살펴보면,Looking at the operation relationship of the reclining apparatus 100 of the present invention as described above,

정지상태와 작동상태로 구분되며 작동상태는 시트백이 전방이나 후방 어느방향이든 상관없이 작동상태로 본다.It is divided into a stationary state and an operating state. The operating state is regarded as the operating state regardless of whether the seatback is in the forward or rearward direction.

정지상태에서는 로어투스브라켓(102)에 형성되는 캠홀(105)에 삽입되어 있는 캠(110)의 양측에 형성된 걸림턱(113)에 캠스프링(118)에 의하여 캠(110)방향으로벌어진 웨지블럭(111,112)의 걸림턱(114)이 치합된 상태가 됨으로서 캠(110)은 의 캠홀(105)에 단속되어 캠(110)이 위치하는 어퍼투스(103)와 로어투스(104)의 갭이 없어지도록 한다.In the stationary state, the wedge block opened in the direction of the cam 110 by the cam spring 118 on the engaging jaw 113 formed on both sides of the cam 110 inserted into the cam hole 105 formed in the lower tooth bracket 102. Since the engaging jaw 114 of the 111 and 112 is engaged, the cam 110 is interrupted by the cam hole 105, so there is no gap between the upper tooth 103 and the lower tooth 104 where the cam 110 is located. To lose.

상기와 같이 어퍼투스(103)와 로어투스(104)의 맞물린 부위의 갭이 없어지므로 시트백이 정지상태에서 유동하거거나 그로인한 이음발생이 없어지게 되며, 쾌적한 승차감을 유지할 수 있게된다.As described above, the gap between the engaging portion of the upper tooth 103 and the lower tooth 104 is eliminated, so that the seatback flows in a stationary state or thereby, no joint occurs, and thus a comfortable riding comfort can be maintained.

이러한 상태에서 리클라이닝장치(100)를 작동시키고자 할 경우에는 커버플레이트(120)에 결합되어 시트백의 외측으로 돌출된 노브(손잡이)를 리클라이닝하고자 하는 작동시키면 시트백이 리클라이닝되는 것이다.When the reclining apparatus 100 is to be operated in this state, the seatback is reclined when the reclining knob (the handle) coupled to the cover plate 120 protrudes out of the seatback.

물론, 이 때 사용되는 노브는 사용자가 직접 회전시켜야 하는 노브일 수 있고 스위치에 의하여 정,역방향으로 회전하는 모터로 구비하여도 됨은 당연할 것이다.Of course, the knob used at this time may be a knob to be rotated by the user directly, it will be obvious that the motor may be provided in the forward and reverse direction by the switch.

본 발명에서는 예시적으로 커버프레레이트(120)를 도면상(도 7) 우측방향으로 회전시키는 것을 설명한다.In the present invention, by rotating the cover plate 120 to the right in the drawing (Fig. 7) by way of example.

노브를 이용하여 커버플레이트(120)를 우측방향으로 회전시키면 커버플레이트(120)에 형성된 작동홀(122)이 일정량 공회전한 후 작동홀(122)에 수용된 캠(110)과 웨지블럭(111,112)의 작동돌기(115,116) 중 회전방향의 브레이크블럭(112)의 작동돌기(116)를 회전방향으로 밀어 걸림턱(113,114)으로 치합되어 있던 브레이크블럭(112)을 먼저 분리하게된다.When the cover plate 120 is rotated to the right by using a knob, the operation hole 122 formed on the cover plate 120 rotates a predetermined amount, and then the cam 110 and the wedge blocks 111 and 112 of the cam 110 accommodated in the operation hole 122 are rotated. Among the actuating protrusions 115 and 116, the actuating protrusion 116 of the brake block 112 in the rotational direction is pushed in the rotational direction to separate the brake block 112 engaged with the locking jaws 113 and 114.

이러한 상태에서 커버플레이트(120)의 작동홀(121)이 캠(110)의 작동돌기(115)를 회전방향으로 계속하여 밀어줌으로서 캠(110)은 로어투스브라켓(102) 형성된 캠홀(105)을 따라 회전함으로서 로어투스(104)가 어퍼투스(103)와 맞물려 회전함으로서 시트백이 자연스럽게 리클라이닝 되는 것이다.In this state, the operation hole 121 of the cover plate 120 continuously pushes the operation protrusion 115 of the cam 110 in the rotational direction, so that the cam 110 has a lower tooth bracket 102 with a cam hole 105 formed therein. By rotating along the lower tooth 104 meshes with the upper tooth 103, the seatback is naturally reclined.

이때, 웨지블럭(111,112)를 양측으로 밀고있던 캠스프링(118)은 커버플레이트(120)힘에 의하여 회전방향으으로 밀려지면서 커버플레이트(120)에 의하여 작동되지않는 방향의 브레이크블럭(111)을 밀게 됨으로서 캠(110)이 회전방향으로 움직이는 데 일조할 수 있게된다.At this time, the cam springs 118 pushing the wedge blocks 111 and 112 to both sides are pushed in the rotational direction by the cover plate 120 force and the brake blocks 111 are not operated by the cover plate 120. By being pushed, the cam 110 can help to move in the rotational direction.

물론, 상기 시트백을 반대방향으로 리클라이닝시키고자 할 경우에는 작동수단(70)을 반대방향으로 회전시킴으로서 가능하게 된다.Of course, when reclining the seatback in the opposite direction, it is possible to rotate the operating means 70 in the opposite direction.

이상과 같은 본 발명은 리클라이닝장치를 구성하는 관련부품을 개선하여 제작과 조립의 용이성을 제공하도록 하여 생산성과 원가절감에 기여할 수 있도록 하는 것은 물론, 원활한 작동이 가능하도록 함으로서 리클라이닝장치의 품질을 높이고 사용자들의 편의성 향상에 기여할 수 있는 등 다양한 효과를 얻을 수 있다.As described above, the present invention improves the quality of the reclining apparatus and improves the quality of the reclining apparatus by enabling the smooth and easy operation as well as contributing to productivity and cost reduction by improving the related parts constituting the reclining apparatus to provide ease of manufacture and assembly. Various effects can be obtained, which can contribute to their convenience.
