Description
본 발명은 자동차용 시트백의 요추조절장치에 관한 것으로서 더욱 상세하게는 승차자의 허리등뼈인 요추(腰椎)부위를 안정적으로 받쳐주어 승차자들의 바른 자세를 유지할 수 있도록 한 개선된 요추조절장치의 제공에 관한 것이다.The present invention relates to a lumbar spin control device of a seat back for an automobile, and more particularly, to provide an improved lumbar spin control device which stably supports a lumbar spine, which is the back spine of a rider, to maintain a correct posture of riders. will be.
시트백에 구비되는 요추받침장치는 승차자의 요추부위를 받쳐주어 바른자세를 유지할 수 있도록 함으로서 승차감의 향상과 충,추돌 시 야기될 수 있는 신체적인 손상을 최소화 할 목적으로 설치된다.The lumbar support device provided in the seatback is installed to support the occupant's lumbar region to maintain the correct posture, thereby improving the riding comfort and minimizing the physical damage that may occur during collision and collision.
이러한 요추받침장치가 종래에도 개발되어 시트백에 설치되고 있으며 그 대표적인 예를 도 5를 통하여 살펴보면 다음과 같다.Such a lumbar support device has been developed in the related art and installed in a seat back, and a representative example thereof will be described with reference to FIG. 5.
헤드레스트 삽입을 위한 헤드레스트가이드를 상측에 고정하고 그 하방에 횡방향으로 고정되는 어퍼바와 시트백의 쿠션을 제공하기 위한 S타입의 스프링을 순차적으로 고정하고, 양측 전방으로는 리클라이너의 어퍼투스브라켓을 고정하면서 시트백의 양측면 형상을 유지하기 위한 브라켓(1)을 돌출시킨 시트백프레임(2)상간에 요추받침장치(5)가 설치된다.The headrest guide for inserting the headrest is fixed on the upper side, and the S type spring for providing the cushion of the seat back and the upper bar fixed in the transverse direction below it is fixed in sequence. The lumbar support device 5 is installed between the seat back frame 2 which protrudes the bracket 1 for maintaining both side shapes of the seat back while fixing it.
상기 요추받침장치(5)는 상기 브라켓(1)을 관통하는 작동축(6)을 구비하여 상기 작동축(6)의 외측에는 레버(7)를, 내측단부에는 다각형상의 캠(8)을 고정한다.The lumbar support device (5) has an operating shaft (6) penetrating the bracket (1) to fix the lever (7) on the outside of the operating shaft (6), the inner end portion of the polygonal cam (8) do.
상기 캠(8)에는 브라켓(1)에 양단부가 움직임이 자유롭게 고정되고 중앙에는 패드(9)를 가지는 작동바(10)가 안치되도록 구성한다.Both ends of the cam 8 are freely fixed to the bracket 1, and an operating bar 10 having a pad 9 is disposed in the center thereof.
상기와 같은 요추받침장치의 작동은 레버를 움직임으로서 캠이 작동바의 돌출정도를 달리하게 되고, 상기 작동바에 구비되는 패드가 시트백의 전방으로 출입하여 요추를 받쳐주게된다.As described above, the operation of the lumbar support device causes the cam to vary the degree of protrusion of the operation bar by moving the lever, and the pad provided on the operation bar enters the front of the seat back to support the lumbar spine.
상기와 같은 종래의 기술에서는 패드가 허리 바로 위의 한 곳만 받쳐주기 때문에 안정적인 자세를 유지할 수 없는 단점을 가지고, 레버와 캠이 움직인 상태를 지속적으로 유지하기 위한 별도의 수단이 없기 때문에 조절된 상태가 해제되는 경우가 다발하기 때문에 불편한 점이 상당히 있는 실정이다.In the prior art as described above, the pad supports only one place directly above the waist, and thus has a disadvantage in that it cannot maintain a stable posture, and there is no separate means for continuously maintaining the state where the lever and the cam are moved. Since there are a lot of cases that are released, the situation is quite uncomfortable.
이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명한 것으로서 작동성을 향상시키면서도 요추전체를 안정된 상태를 받쳐 지지할 수 있도록 함으로서 사용자들의 승차자세의 유지와 안전성을 확보하여 승차감을 높이도록 함은 물론 시트 자체의 품질과 성능향상에 기여할 수 있도록 하는데 목적이 있다.Therefore, in the present invention to solve the above problems as well as to improve the operability while supporting the entire lumbar spine to support a stable state to maintain the riding posture of users to ensure a safe ride as well as of course The purpose is to contribute to improving the quality and performance of the sheet itself.

요추받침장치(30)는 헤드레스트 삽입을 위한 헤드레스트가이드(31)를 상측에 고정하고 그 하방에 횡방향으로 고정되는 어퍼바(32)와 시트백의 쿠션을 제공하기 위한 S타입의 스프링(33)을 순차적으로 고정하고, 양측 전방으로는 리클라이너의 어퍼투스브라켓을 고정하면서 시트백의 양측면 형상을 유지하기 위한 브라켓(34)을 돌출시킨 시트백프레임(35)상간에 설치된다.The lumbar support device (30) is an S-type spring (33) for providing an upper bar (32) for fixing the headrest guide (31) for inserting the headrest on the upper side and a lower portion thereof and a cushion for the seat back. ) Is sequentially fixed to both sides and is installed between the seat back frame 35 protruding the bracket 34 for maintaining both sides of the seat back while fixing the upper bracket of the recliner.
상기 요추받침장치(30)는 내측단부에 구동기어(36)를 가지고 브라켓(34)의 일측면에 정,역방향에 관계없이 작동한 상태를 유지하여주는 통상적인 브레이크드럼(37)을 장착하고, 상기 브레이크드럼(37)의 외측으로 돌출되는 축(38)에는 작동노브(39)를 결합한다.The lumbar support device (30) is equipped with a conventional brake drum (37) having a drive gear (36) at the inner end and maintaining a state of operation regardless of the forward and reverse directions on one side of the bracket (34), The operating knob 39 is coupled to the shaft 38 protruding outward of the brake drum 37.
상기 구동기어(36)에는 브라켓(34)의 내측에서 회전자유롭게 고정되는 부채꼴 형상의 피동기어(40)를 맞물리도록 하고, 상기 피동기어(40)에는 하향돌출된 레버(41)를 함께 고정한다.The drive gear 36 is engaged with the fan-shaped driven gear 40 which is freely fixed to the inside of the bracket 34, and the downwardly protruding lever 41 is fixed to the driven gear 40 together.
상기 레버(41)에는 대향측의 브라켓(34) 내측에 고정되는 지지판(42)과 움직임이 자유로운 작동바(43)를 연결하여 노브(39)의 움직임이 구동기어(36)와 피동기어(40) 및 레버(41)를 통하여 전달받아 시트백의 전,후방으로 출입할 수 있도록 한다.The lever 41 is connected to the support plate 42 fixed inside the bracket 34 on the opposite side and the movable bar 43 freely movable, so that the movement of the knob 39 is driven by the drive gear 36 and the driven gear 40. ) And received through the lever 41 to allow access to the front and rear of the seat back.
상기 작동바(43)에는 일정폭과 높이를 가지는 패드(45)를 고정하고, 상기 패드(45)와 시트백프레임(35)의 어퍼바(32) 상간에는 탄성을 가지는 강선을 개략 ∪형상으로 절곡한 지지바(46)를 더 구비하여 요추 전체를 받쳐줄 수 있도록 구성한다.The pad 45 having a predetermined width and height is fixed to the operation bar 43, and a steel wire having elasticity is bent in a roughly ∪ shape between the pad 45 and the upper bar 32 of the seat back frame 35. One support bar 46 is further provided to support the entire lumbar spine.
상기와 같은 본 발명의 요추받침장치(30)는;Lumbar support device 30 of the present invention as described above;
시트백의 일측방에 구비되는 작동노브(39)를 정,역방향으로 회전시킴으로서 시트백의 쿠션이 출입하여 시트백에 밀착되는 승차자의 요추부위를 받쳐주어 승차자세를 편안하게 하는 것이다.By rotating the operating knob 39 provided on one side of the seat back in the forward and reverse directions, the cushion of the seat back enters and supports the lumbar region of the occupant who is in close contact with the seat back, thereby making the riding position comfortable.
이러한 일련의 동작을 살펴보면, 작동노브(39)를 회전시킴으로서 축(38)을 통하여 구동기어(36)가 회전하여 부채꼴 형상의 피동기어(40)를 회전시키게 되고, 상기 피동기어(40)의 회전으로 피동기어(40)에 고정된 레버(41)도 함께 회전하여 작동바(43)를 움직이게 된다.Looking at this series of operations, by rotating the operating knob 39, the drive gear 36 is rotated through the shaft 38 to rotate the fan-shaped driven gear 40, the rotation of the driven gear 40 As a result, the lever 41 fixed to the driven gear 40 also rotates to move the operation bar 43.
상기 작동바(43)의 움직임으로 작동바(43)에 고정된 패드(45)가 시트백의 쿠션을 출입시키게 되고, 상기 패드(45)와 시트백프레임(35)의 상측에 구비되는 어퍼바(32) 상간에 더 연결된 지지바(46)역시 패드(45) 상측부위의 쿠션을 출입시킴으로서 시트백의 쿠션이 승차자의 요추와 동일한 형상으로 출입하면서 지지하게 되는 것이다.The pad 45 fixed to the operating bar 43 moves the cushion of the seat back by the movement of the operating bar 43, and the upper bar 32 provided on the upper side of the pad 45 and the seat back frame 35. ) The support bar 46 further connected between the upper and lower seats also allows the cushion of the upper portion of the pad 45 to enter and exit while supporting the cushion in the seatback in the same shape as the lumbar spine of the occupant.
그리고, 작동노브(39)를 회전시켜 패드(45)와 지지바(46)를 움직인 후 작동로브(39)를 놓게되면 브레이크드럼(37)의 브레이킹 작동으로 패드(45)와 지지바(46)를 조절한 상태로 계속하여 유지하여 줌으로서 중도에 복귀하는 등의 현상을 방지할 수 있는 것이다.Then, when the operation knob 39 is rotated to move the pad 45 and the support bar 46 and then the operation lobe 39 is released, the pad 45 and the support bar 46 are braked by the brake drum 37. ) Can be kept in the adjusted state to prevent the phenomenon such as returning to the middle.
이상과 같은 본 발명은 승차자의 요추전체를 안정된 상태를 받쳐 지지할 수 있도록 구성하면서도 원활한 작동성을 가지도록 함으로서 사용자들의 승차자세의 유지와 안전성을 확보하여 승차감을 높이도록 함은 물론 시트 자체의 품질과 성능향상에 기여할 수 있는 등 다양한 효과를 얻을 수 있다. The present invention as described above is configured to support the entire lumbar spine of the rider to support a stable state, while having a smooth operability to ensure the riding position and safety of users to increase the ride comfort as well as the quality of the seat itself And various effects can be achieved.
