본 고안은 시트등받이의 위치설정장치에 관한 것으로, 더욱더 상세하게는 시트등받이의 내부에 설치된 접이장치를 상하로 이동시켜 시트에 착좌한 승원이 신체에 알맞은 위치로 이동시키는 것이 용이하게 이루어지도록 하는 시트등받이의 위치설정장치에 관한 것이다.The present invention relates to a positioning device of the seat back, and more particularly, to move the folding device installed in the interior of the seat back up and down to facilitate the movement of the occupant seated on the seat to a position suitable for the body It relates to a positioning device of the backrest.

일반적으로, 자동차의 내부에 설치되어 탑승자가 착좌하도록 시트의 등받이 내부에는 위치설정장치가 설치되어 있다.In general, the positioning device is installed inside the back of the seat so that the occupant is seated inside the vehicle.

여기에서 종래 시트등받이의 위치설정장치는 제1도에 도시하고 있는 바와 같이, 등받이(12)의 중간에 가로방향으로 접이장치(30)가 조절레버(31)에 의해 전후로 이동가능하게 설치되어 있다.In the conventional seat back positioning device, as shown in FIG. 1, the folding device 30 is installed in the middle of the backrest 12 so as to be movable back and forth by the adjustment lever 31. As shown in FIG. .

이러한 종래 시트등받이의 위치설정장치는 시트(10)에 착좌한 승원이 조절레버(31)를 조작하는 것에 의해 접이장치(30)가 전후로 이동되며 시트(10)에 착좌한 승원의 요추를 받치게 됨으로서, 차량을 장시간 탑승하는 경우에도 차실에 탑승한 승원의 피로감이 저감되도록 하고 있다.Such a conventional seat back positioning device is operated by the occupant seated on the seat 10 to operate the control lever 31, the folding device 30 is moved back and forth to support the lumbar spine of the occupant seated on the seat 10. Thus, even when the vehicle is boarded for a long time, the fatigue of the occupant in the cabin is reduced.

그러나, 이러한 종래 시트등받이의 위치설정장치는 시트(10)에 착좌한 승원이 요추를 받치기 위해 등받이(12)의 중간에 횡방향으로 설치된 접이장치(30)를 조절레버(31)에 의해 조작하는 경우에도, 상기 접이장치(30)가 전후로만 이동이 이루어짐으로서, 시트(10)에 착좌한 승원의 신체가 어린이와 같이 작거나 거구인 경우에는 승원의 신체조건에 알맞은 높이로 접이장치(30)를 이동시키는 것이 불가능하게 하게되고, 이로인해 시트(10)에 착좌한 승원이 요추를 지지받지 못하게 되어 장시가 시트(10)에 착좌한 경우 불편함을 느끼게 되는 문제점이 있었다.However, such a conventional seat back positioning device operates the folding device 30 provided in the middle of the back 12 in the transverse direction by the control lever 31 so that the occupant seated on the seat 10 supports the lumbar spine. Even if the folding device 30 is moved only before and after, when the body of the occupant seated on the seat 10 is small or large, such as a child, the folding device 30 at a height suitable for the physical condition of the occupant. It becomes impossible to move the), which causes the occupant who is seated on the seat 10 not to support the lumbar spine and feels inconvenient when Jiangxi is seated on the seat 10.

본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로, 본 고안의 목적은 시트등받이의 내부에 설치되는 접이장치를 상하고 이동시켜 시트에 착좌한 승원의 신체에 알맞은 위치로 이동되도록 함으로서, 시트에 착좌한 승원의 착좌감을 향상시키고, 차량을 장시간 탑승한 경우에도 피로감이 저감되도록 하는 시트등받이의 위치설정장치를 제공하는 것에 있다.The present invention has been made in view of the above problems, the object of the present invention is to move the folding device installed inside the seat back and to move to a position suitable for the body of the occupant seated on the seat, The present invention provides a seat back positioning device that improves the seating comfort of a seated occupant and reduces fatigue even when the vehicle is boarded for a long time.

상기 목적을 달성하기 위하여 본 고안은 구동력을 부여하는 모터와, 모터축에 연결되는 운동변환장치와, 운동변환장치에서 연장되어 형성된 이송나사축과, 이송나사축에 이송가능하게 나사결합된 워엄기어 하우징과, 양측 워엄하우징 사이에 회동 가능하게 설치되는 접이장치로 이루어짐을 특징으로 한다.In order to achieve the above object, the present invention provides a motor for imparting a driving force, a motion converter connected to a motor shaft, a feed screw shaft extending from the motion converter, and a worm gear screwably coupled to the feed screw shaft. It is characterized by consisting of a folding device that is rotatably installed between the housing, both the worm housing.

이하, 본 고안의 실시예를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings an embodiment of the present invention as follows.

제2도는 본 고안의 구조를 보인 구성도로서, 시트(10)의 등받이(12)내부에는 모터(40)가 양측의 모터축(41)이 양측으로 형성된 운동변환장치(42)에 연결되고, 상기 운동변화장치(42)에는 하우징(60)에 체결된 이송나사축(50)이 연결된다.2 is a block diagram showing the structure of the present invention, the inside of the backrest 12 of the seat 10, the motor 40 is connected to the motion converter 42 formed on both sides of the motor shaft 41, The feed screw shaft 50 coupled to the housing 60 is connected to the motion change device 42.

이와 같은 운동변화장치(42)는 모터(40)가 구동되면 모터축(41)에 형성된 베벨기(80)에 이송나사축(50)이 치합되어 회전되는 것에 의해 워엄기어 하우징(60)이 승하강 된다.The motion change device 42 is the worm gear housing 60 is raised by the rotation of the feed screw shaft 50 is engaged with the bevel machine 80 formed on the motor shaft 41 when the motor 40 is driven. It will descend.

한편, 워엄기어 하우징(60)에는 힌지축(71)이 연결되어 접이장치(70)이 일체로 승하강가능하게 형성된다.On the other hand, the worm gear housing 60, the hinge shaft 71 is connected to the folding device 70 is formed to be raised and lowered integrally.

이상과 같이 구성된 본 고안의 작용 및 효과를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.If described in detail by the accompanying drawings the operation and effects of the present invention configured as described above are as follows.

차실에 탑승한 승원이 시트(10)에 착좌한 후 승원의 신체조건에 대응되는 조건 즉, 탑승자의 신체에 알맞은 높이로 와 요추부위의 각도를 조절하기위해 모터(40)를 스위치(도시않됨)에 의해 구동시키면, 모터(40)에 연장된 모터축(41)은 운동변환장치의 베벨기어(80)를 통해 회전운동방향을 횡방향에서 수직으로 변환시킴과 동시에 회전력을 이송나사축(50)에 전달하게된다.After the occupant seated on the seat 10, the motor 40 is switched to adjust the angle of the lumbar region to a condition corresponding to the physical condition of the occupant, that is, the body corresponding to the occupant's physical condition. When driven by the motor, the motor shaft 41 extending to the motor 40 converts the rotational movement direction from the transverse direction to the vertical direction through the bevel gear 80 of the motion converter and simultaneously transfers the rotational force to the feed screw shaft 50. Will pass on.

이와 같은 상태에서 이송나사축(50)은 워엄기어 하우징(60)을 상,하방향으로 이송시켜 접이장치(70)를 등받이(12)의 내측 상부로 승강시키거나 하부로 하강시켜 높이를 조절하게 된다.In this state, the feed screw shaft 50 moves the worm gear housing 60 in the up and down directions to raise or lower the folding device 70 to the inner upper portion of the backrest 12 or to lower the height to adjust the height. do.

따라서, 탑승자의 신체조건에 알맞은 높이로 등받이(12)의 내부에 설치된 접이장치(70)를 이동시켜 시트(10)에 착좌한 승원이 신체인 요추를 지지하게됨으로서, 시트(10)에 착좌한 승원의 착좌감이 향상됨은 물론, 차량을 장시가 탑승한 경우에도 피로감이 저감되도록 하는 효과가 있다.Accordingly, the crew seated on the seat 10 supports the lumbar spine, which is a body, by moving the folding device 70 installed inside the backrest 12 to a height appropriate to the physical condition of the occupant, thereby seating on the seat 10. The seating feeling of the crew is improved, as well as the fatigue is reduced even when the vehicle is a long ride.

이상에서 살펴 본 바와 같이 본 고안은 시트의 등받이 내부에 설치된 접이장치를 탑승자의 체형에 알맞은 위치로 이동시켜 사용하는 것이 용이하게 이루어지도록 하는 매우 유용한 고안이다.As described above, the present invention is a very useful design to facilitate the use of the folding device installed inside the backrest of the seat to a position suitable for the occupant's body shape.
