본 고안은 의자등받이 구동장치에 관한 것으로, 특히 시트쿠션과 회전가능하게 결합되고 역진기능이 부가된 감속모터에 의해 회전되도록 된 등받이에 전방측으로 잡아당겨 주는 스프링을 설치하여 의자에 착석한 사람이 등받이 쪽으로 기대는 힘을 이 스프링에 저장하였다가 등받이를 전방측으로 움지기여줄 때 감속모터에 걸리는 부하를 상기 스프링이 덜어주도록 하여 감속모터를 정·역전시킬때 받게 되는 부하의 불균형을 어느정도 같아 지도록 한 의자등받이 구동장에 관한 것이다.The present invention relates to a chair back driving device, and in particular, a seat seated on a chair is provided with a spring that pulls forward on a backrest that is rotatably coupled with a seat cushion and is rotated by a deceleration motor having a reverse function. The chair that stores the force leaning against this spring and relieves the load applied to the reduction motor when the backrest is moved forward, so that the load imbalance when receiving and reversing the reduction motor is equalized. It relates to a backrest drive field.

일반적인 의자는 착석한 사람의 편의를 위해 등받이와 시트쿠션이 회전되는 구조에 등받이를 전·후로 기울여 조정할 수 있도록 되어 있으며, 특히 자동차용 의자는 운전중에 더 많은 편의를 제공하기 위해 전기동력을 이용한 전동모터를 상기 등받이의 기울기 조정에 쓰도록 하여 운전중에는 별로 큰 힘을 들이지 않고 간단한 스위치조작에 의해 등받이의 기울기를 조절할 수 있도록 하고 있다.The general chair is designed to tilt the backrest forward and backward in a structure in which the backrest and the seat cushion are rotated for the convenience of the seated person. In particular, the chair for the motor is powered by electric power to provide more convenience while driving. The motor is used to adjust the inclination of the backrest so that the inclination of the backrest can be adjusted by a simple switch operation without much force during operation.

이러한 등받이의 기울기를 전동력으로 조절할 수 있도록 한 의자의 한 예를 첨부도면 제1도 및 제2도에 도시하였는데 이에 도시된 바와 같이 시트쿠션(10)을 지지하는 쿠션프레임(11)에 등받이(12)의 골격에 해당하는 등받이프레임(13)이 회전가능하게 결합되어 있으며, 등받이프레임(13)측에는 역진기능이 부가된 감속모터(14)가 설치되어 스위치(SW1)의 조작에 의해 등받이프레임(13)이 전·후방향으로 회전운동하여 기울기가 조절되도록 구성된 것이다.An example of a chair capable of adjusting the inclination of the backrest by the electric force is illustrated in FIGS. 1 and 2 of the accompanying drawings, and as shown in FIG. 12, the backrest 12 is provided on the cushion frame 11 supporting the seat cushion 10. Back frame 13 corresponding to the frame of the frame is rotatably coupled, the back frame 13 is provided with a deceleration motor 14 with a reverse function is attached to the back frame 13 by the operation of the switch (SW1) ) Is configured to adjust the tilt by rotating forward and backward.

그러나 이와 같은 종래의 의자등받이 구동장치는 제2도에 도시된 바와 같이 착석자의 기대는 힘(도면중 화살표 A로 표시된 부분) 때문에 도면중 화살표 A로 표시된 힘의 방향과 같은 방향인 등받이(12)를 후방측으로 눕힐때는 착석자의 기대는 힘이 부가되어 감속모터(14)에 걸리는 부하가 적어지는 반면에 도면중 화살표 B와 같은 방향인 상기 착석자가 기대는 힘의 방향(도면중 화살표 A방향)과 반대방향으로 상기 등받이(12)를 세울때는 착석자의 기대는 힘을 이겨내는 힘과 등받이(12)를 세우는데 드는 힘의 합보다 감속모터(14)의 힘이 커야 등받이(12)가 세워지므로 그만큼 감속모터(14)에는 눕힐때 보다 큰 부하가 걸리게 되어 있으므로 감속모터(14)를 값비싼 큰 용량(보통 자동차의 경우 → 10Amp 용량)의 것을 사용하여야 되는 비경제적인 문제점이 있었다.However, such a conventional chair back drive device has a backrest 12 that is in the same direction as the direction of the force indicated by arrow A in the figure because of the leaning force of the occupant (shown by arrow A in the figure) as shown in FIG. When it is laid on the rear side, the load of the seated person's leaning force is added to reduce the load on the reduction motor 14, while the direction of the seated person's leaning force in the same direction as arrow B in the figure (arrow A direction in the figure) and When the backrest 12 is raised in the opposite direction, the backrest 12 is erected only when the power of the reduction motor 14 is greater than the sum of the force of the seated person's leaning force and the force required to raise the backrest 12. Since the deceleration motor 14 takes a larger load when laid down, there is an uneconomical problem in that the deceleration motor 14 needs to use an expensive large capacity (usually → 10 amp capacity in the case of a car).

본 고안은 상기한 바와 같은 문제점을 해소하고자 안출된 것으로 시트쿠션에 회전가능하게 설치된 등받이를 전후방향으로 세우거나 기울일때 전동모터가 받게 되는 부하량의 불균형이 평균치로 딜 수 있도록 하여 이 기존 의자등받이 구동장치가 필요로 하는 전동모터의 최대용량을 낮추려는데 그 목적이 있다.The present invention is designed to solve the problems as described above, so that the unbalance of the load received by the electric motor can be delivered to the average value when the backrest, which is rotatably installed on the seat cushion, is tilted forward or backward to drive the existing chair back. The purpose is to reduce the maximum capacity of the electric motor required by the device.

이러한 본 고안의 목적을 달성하기 위하여 시트쿠션을 지지하는 쿠션프레임에 등받이를 지지하는 등받이프레임이 회전가능하게 결합되어 있고, 이 등받이프레임을 전·후방향으로 눕히거나 세울 수 있는 전동모터가 구비된 의자등받이 구동장치에 있어서, 상기 등받이프레임이 세워지는 방향으로 탄성력을 주는 스프링의 양단을 이 등받이프레임과 상기 쿠션프레임에 각각 설치하여 의자등받이 구동장치가 제공된다.In order to achieve the object of the present invention, the backrest frame for supporting the backrest is rotatably coupled to the cushion frame for supporting the seat cushion, and is provided with an electric motor that can lay or stand the backrest frame forward and backward. In the chair back drive device, a chair back drive device is provided by installing both ends of the spring which give elasticity in the direction in which the back frame is erected on the back frame and the cushion frame, respectively.

이하 본 고안에 따른 의자등받이 구동장치의 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of a chair back driving device according to the present invention will be described in detail with reference to the accompanying drawings.

제3도 및 제4도는 본 고안에 따른 의자등받이 구동장치의 실시예를 도시한 사시도 및 측면개략도로서, 이에 도시한 바와 같이 시트쿠션(20)을 지지하는 쿠션프레임(21)에 등받이(22)를 지지하는 등받이프레임(23)이 회전가능하게 결합되어 있고, 이 등받이프레임(23)을 전·후방향으로 눕히거나 세울 수 있는 전동모터(24)가 구비된 의자등받이 구동장치에 있어서, 상기 등받이프레임(23)이 세워지는 방향으로 탄성력을 주는 스프링(30)의 양단(31)(32)을 이 등받이프레임(23)과 상기 쿠션프레임(21)에 각각 설치하여 구성하였다.3 and 4 are a perspective view and a side view showing an embodiment of the chair back drive device according to the present invention, as shown in the backrest 22 to the cushion frame 21 for supporting the seat cushion 20 as shown therein The backrest frame 23 supporting the back is rotatably coupled, and the backrest drive device provided with the electric motor 24 which can lay or stand the backrest frame 23 forward and backward, The backrest Both ends 31 and 32 of the spring 30, which give the elastic force in the direction in which the frame 23 is erected, were installed on the backrest frame 23 and the cushion frame 21, respectively.

여기에서 상기 스프링(30)은 도시예에서와 같이 인장코일 스프링으로 구성될 수 있으며, 상기 전동모터(24)는 일반적인 모터로서 역진기능이 부가된 감속기 붙이 모터로 구성되어 있다.Here, the spring 30 may be configured as a tension coil spring as shown in the example, the electric motor 24 is a general motor is composed of a motor with a reduction gear is added to the reverse function.

도면중 미설명 부호 40은 상기 전동모터(24)에 접속된 커넥터를 나타낸 것이며, 41은 의자를 나타낸 것이고, 42는 착석자를 나타낸 것이며, 43은 상기 착석자(42)의 등을 나타낸 것이다.In the figure, reference numeral 40 denotes a connector connected to the electric motor 24, 41 denotes a chair, 42 denotes a seated person, 43 denotes a seated person 42 and the like.

이상에서와 같은 본 고안의 실시예에 따른 작용·효과를 설명한다.The action and effect according to the embodiment of the present invention as described above will be described.

의자(41)에 사람이 착석하여 등(43)을 등받이(22)에 기대고 있는 상태에서 전동모터(24)를 회전시켜 도면중 화살표 C로 표시된 방향으로 등받이(22)를 눕히게 되면, 도면중 화살표 D로 표시된 힘의 방향을 가진 착석자(42)의 기대는 힘(F)이 스프링(30)을 인장시키는 힘으로 변환되어 이 스프링(30)에 저장된다.When a person is seated on the chair 41 and the electric motor 24 is rotated while the back 43 is leaning on the back 22, the back 22 is laid down in the direction indicated by the arrow C in the drawing. The reclining force F of the seated occupant 42 with the direction of force indicated by arrow D is converted into a force for tensioning the spring 30 and stored in this spring 30.

한편, 상기와는 반대로 착석자(42)가 등받이(22)에 기대고 있는 상태에서 전동모터(24)를 구동시켜 이 등받이(22)를 도면중 화살표 E방향으로 세우게 되면, 이것과 반대방향으로 작용하는 착석자(42)의 기대는 힘(F)은 상기 스프링(30)의 인장력에 의해 소멸되면서 상기 전동모터(24)에 부하를 걸어주지 못하므로 등받이(22)는 처음의 눕힐 때와 거의 같은 힘으로 세워지게 된다.On the other hand, in contrast to the above, when the seated person 42 is leaning against the backrest 22, the electric motor 24 is driven to raise the backrest 22 in the direction indicated by arrow E in the drawing. Reclining force (F) of the seated person (42) is extinguished by the tension of the spring (30) can not apply the load to the electric motor 24, so the backrest 22 is almost the same as when the first lying down It is built up by force.

이상에서와 같은 본 고안은 등받이를 세우거나 눕힐 수 있는데, 사용되는 전동모터의 부하용량을 기존보다 작은 것을 사용할 수 있어 의자등받이 구동장치의 전체적인 제작비용을 절감할 수 있음은 물론이고, 전동모터를 구동하는데 소용되는 전력을 기존의 것보다 줄일 수 있어 전력절감 효과도 얻을 수 있는 매우 유용한 고안인 것이다.The present invention as described above can stand or lay the back, the load capacity of the used electric motor can be used smaller than the conventional can reduce the overall manufacturing cost of the chair back drive device, as well as the electric motor It is a very useful design that can reduce the power used to drive than the existing one, and can also achieve a power saving effect.
