Description

의자의 등받이{the back of a chair}The back of a chair}

본 발명은 의자의 등받이에 관한 것으로서, 특히 사용자가 등을 뒤로 젖힐 시 상체를 일정하게 받치는 의자의 등받이에 관한 것이다.The present invention relates to a backrest of a chair, and more particularly to a backrest of a chair that constantly supports the upper body when the user leans back.

일반적으로 의자는, 좌판과 소정의 각도를 이루면서 등받이가 세워지며, 좌판의 하측에는 회전다리가 결합된 구조이며, 상기 좌판 및 등받이에는 스폰지등의쿠션부재가 내장된 외피가 싸고 있는 구조이다.In general, the chair has a predetermined angle with the seat plate, the backrest is erected, the lower side of the seat plate is a structure coupled to the rotating legs, the seat plate and the backrest is a structure in which the outer shell with a cushion member such as sponge is built.

한편, 사용자가 등을 뒤로 젖혀 등받이를 틸팅할 수 있게 틸팅수단이 좌판의하측에 구비되어 사용자가 스트레칭 등을 용이하게 할 수 있다. 상기 틸팅수단은, 회전다리의 상측에 틸팅케이스가 결합되고, 이 틸팅케이스의 내부에는 스프링 및 링크가 수용되어 좌판의 후측이 기울어진 후 복원되는 구조이다.On the other hand, the tilting means is provided on the lower side of the seat plate so that the user can tilt the back by tilting the back, the user can facilitate the stretching and the like. The tilting means has a structure in which a tilting case is coupled to an upper side of the rotating leg, and a spring and a link are accommodated in the tilting case so that the rear side of the seat is inclined and restored.

그런데, 인체의 척추는 요추가 오목하게 들어가 있어 등부분이 상하방향으로 곡면을 이루고 있으므로, 종래 틸팅가능한 의자에서는 사용자가 등을 뒤로 젖히면, 등받이와 사용자의 요추부분의 사이에 공간이 발생하게 되고 이로 인해 요추를 충분히 지지할 수 없는 등, 사용자의 상체를 전체적으로 일정하게 받쳐주지 못한다는 문제점이 있었다.However, since the spine of the human body is concave in the lumbar spine, and the back portion is curved up and down, in the conventional tiltable chair, when the user leans back, a space is generated between the backrest and the lumbar part of the user. There was a problem that the upper body of the user can not be uniformly supported, such as not enough to support the lumbar spine.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 사용자가 등을 뒤로 젖힐 시 요추를 충분히 지지할 수 있으며 사용자의 상체를 전체적으로 일정하게 받치는 의자의 등받이를 제공하는 데 있다.Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a backrest of a chair that can sufficiently support the lumbar spine when the user leans back and supports the user's upper body constantly.

상기 등받이(14)는, 대체로 사각으로 된 플렉시블한 등판프레임(24)과, 상기등판프레임(24)의 후측에서 등판프레임을 지지하는 소정의 강성을 가진 등판지지프레임(26)을 구비한다. 상기 등판프레임(24)은 플렉시블한 커버(천, 가죽, 비닐등)가 싸고 있으며, 플렉시블한 커버의 내부에는 필요에 따라 스폰지등의 쿠션부재가 내장된다. 도면에서는 플렉시블 커버 및 쿠션부재가 생략되어 있다.The backrest 14 includes a generally flexible flexible backing frame 24 and a backing support frame 26 having a predetermined rigidity supporting the backing frame at the rear side of the backing frame 24. The back frame 24 is wrapped in a flexible cover (cloth, leather, vinyl, etc.), and a cushion member such as a sponge is embedded in the flexible cover as necessary. In the drawings, the flexible cover and the cushion member are omitted.

상기 등판프레임(24)의 상단은 상기 등판지지프레임(26)의 상단과 힌지점(P1)으로 힌지결합되고, 상기 등판프레임(24)의 하단은 상기 틸팅케이스의 제2링크(21)와 좌판의 후단을 연결하는 지지대(28)에 힌지점(P2)으로 힌지결합된다. 그리고, 상기 지지대(28)의 중간부는 상기 좌판(10)의 후단에 힌지점(P3)으로 힌지결합되며, 지지대(28)의 전단은 상기 제2링크(21)의 하단에 힌지점(P4)로 힌지결합된다.The upper end of the back frame 24 is hinged to the upper end of the back support frame 26 and the hinge point (P1), the lower end of the back frame 24 is the second link 21 and the seat plate of the tilting case Hinge point (P2) is coupled to the support 28 to connect the rear end of the. The intermediate portion of the support 28 is hinged to the rear end of the seat plate 10 at a hinge point P3, and the front end of the support 28 is hinged at a lower end of the second link 21. Hinged together.

상기 등판지지프레임(26)은, 그 상단이 상기 등판프레임(24)의 상단에서 상기 힌지점(P1)으로 힌지결합되고, 그 중간부가 의자의 회전다리(16)측으로 후퇴되면서 구부려진 다음, 좌판(10)측으로 상승하면서 연장되어 좌판의 중간부 저면에 힌지점(P5)으로 힌지결합된 다음, 틸팅케이스의 상기 제1링크(20)의 상단에 힌지점(P6)으로 힌지 결합된다.The back support frame 26, the upper end is hinged to the hinge point (P1) at the upper end of the back frame 24, the middle portion is bent while being retracted toward the rotation leg 16 side of the chair, then the seat plate Extending while extending to the (10) side is hinged to the hinge point (P5) to the bottom of the middle portion of the seat plate, and then hinged to the hinge point (P6) of the upper end of the first link 20 of the tilting case.

상기 제1링크(20)의 힌지점(P6)와 상기 제2링크(21)의 힌지점(P4)는 틸팅시 위치가 변하지 않는 고정점이고, 상기 제1링크(20)의 하단과 상기 제2링크(21)의 상단은 틸팅시 그 위치가 변하게 된다.The hinge point P6 of the first link 20 and the hinge point P4 of the second link 21 are fixed points at which the position does not change during tilting, and the lower end of the first link 20 and the second point. The upper end of the link 21 changes its position when tilting.

이와 같이 구성된 본 발명에 의한 의자의 등받이의 틸팅상태가 도2로 도시되어 있다. 도면은 힌지점(P1)과 힌지점(P2)사이의 거리(L1)가 약 541mm이고,좌판(10)의 수평면을 기준으로 힌지점(P2)와 힌지점(P3)를 잇는 선이 이루는 각(θ1)이 약 4°이고, 제1링크(20)의 하단과 제2링크(21)의 상단사이의 거리(L3)가 약 70mm인 의자를 틸팅하여 시험한 상태이다.Tilt state of the back of the chair according to the present invention configured as described above is shown in FIG. In the drawing, the distance L1 between the hinge point P1 and the hinge point P2 is about 541 mm, and an angle formed by a line connecting the hinge point P2 and the hinge point P3 with respect to the horizontal plane of the seat 10. (1) is about 4 ° and the chair is tested by tilting a chair having a distance L3 of about 70 mm between the lower end of the first link 20 and the upper end of the second link 21.

도시한 바와 같이 사용자가 등을 뒤로 젖혀서 힌지점(P6)와 힌지점(P5)를 잇는 선이 하측으로 이루는 각(θ2)이 약 20°가 되게 틸팅한 결과, 거리(L1)은 거리(L1')로 변하여 약 488mm되고, 거리(L3)는 거리(L3')로 변하여 약 87mm가 되었다.As shown in the figure, the user tilts his back and tilts the angle θ2 of the line connecting the hinge point P6 and the hinge point P5 to the lower side so that the angle θ2 is about 20 °. As a result, the distance L1 is the distance L1. ') Changed to about 488mm, and the distance L3 was changed to the distance L3' and became about 87mm.

즉, 힌지점(P1)과 힌지점(P2)사이의 거리가 541mm에서 487mm로 축소되어, 그 축소된 거리는 등판프레임(24)의 볼록부(M)로 나타나게 되어 사용자의 요추를 받치면서 사용자의 상체를 전체적으로 일정하게 받치게 된다.That is, the distance between the hinge point (P1) and the hinge point (P2) is reduced from 541mm to 487mm, the reduced distance is represented by the convex portion (M) of the back frame 24 to support the user's lumbar spine The upper body is supported uniformly throughout.

본 발명에 의한 의자의 등받이에 의하면, 사용자가 등을 뒤로 젖혀 등판프레임을 틸팅할 시에 등판프레임이 변형되어 요추를 충분히 지지할 수 있으며 사용자의 상체를 전체적으로 일정하게 받치는 효과가 있다.According to the backrest of the chair according to the present invention, when the user tilts the back frame by tilting the back, the back frame is deformed to sufficiently support the lumbar spine, and the upper body of the user is uniformly supported.
