상기 각도 조절 수단(700a)은, 하우징(701a)과, 상기 하우징(701a)의 내측에 형성된 수용부(702a)와, 상기 수용부(702a)에 수용된 톱니부(703a)와, 상기 톱니부(703a)의 하부에 배치되며 스위칭 레버(707a)의 조작에 연동하여 회전하는 모서리가 라운드진 대략 삼각형의 스위칭 부재(704a)와, 상기 스위칭 부재(704a)의 좌우 양측에 위치하는 2개의 스토퍼(705a)와, 상기 스토퍼(705a)를 상기 스위칭 부재(704a) 쪽으로 가압하는 스프링(706a)을 포함한다.       The angle adjusting means 700a includes a housing 701a, an accommodating portion 702a formed inside the housing 701a, a tooth portion 703a accommodated in the accommodating portion 702a, and the tooth portion ( A substantially triangular switching member 704a, which is disposed below 703a and rotates in conjunction with the operation of the switching lever 707a, and two stoppers 705a positioned on both left and right sides of the switching member 704a. ) And a spring 706a for urging the stopper 705a toward the switching member 704a.
상기 스프링(706a)은 일단이 상기 수용부(702a)의 벽면에 지지되고 타단이 상기 스토퍼(705a)에 지지되어 상기 스토퍼(705a)를 상시 상기 스위칭 부재(704a) 쪽으로 가압한다. 따라서, 상기 스토퍼(705a)가 상기 스위칭 부재(704a)의 모서리와 접촉하고 있을 때에는, 상기 스토퍼(705a)와 상기 톱니부(703a)가 서로 이격되어 있게 되나, 상기 스위칭 부재(704a)가 회전하여 모서리가 아니라 한 변이 상기 스토퍼(705a)와 접촉하는 경우에는 경사지게 배치되어 있던 상기 스토퍼(705a)가 수직하게 배치되므로 톱니부(703a)와 접촉하게 된다.        One end of the spring 706a is supported by the wall surface of the accommodation portion 702a and the other end is supported by the stopper 705a to press the stopper 705a toward the switching member 704a at all times. Therefore, when the stopper 705a is in contact with the edge of the switching member 704a, the stopper 705a and the tooth 703a are spaced apart from each other, but the switching member 704a is rotated. When one side of the stopper 705a does not contact an edge, the stopper 705a which is disposed to be inclined is vertically disposed, so that the side of the stopper 705a comes into contact with the tooth 703a.

상기 상단 프레임(120d) 및 하단 프레임(220d)은 그 외측에 부착되는 상단 틸트 조절 수단(900d), 하단 틸트 조절 수단(800d), 및 각도 조절 수단(700d)을 통해 의자의 상부에 결합된다.       The upper frame 120d and the lower frame 220d are coupled to the upper part of the chair through the upper tilt adjusting means 900d, the lower tilt adjusting means 800d, and the angle adjusting means 700d attached to the outside thereof.
먼저, 상단 틸트 조절 수단(900d) 및 하단 틸트 조절 수단(800d)은 도21에 정면에서 바라본 단면도가 도시되어 있으며, 도22에 우측에서 바라본 내부 구조가 도시되어 있다. 상기 2개의 틸트 조절 수단(800d, 900d)은 현재 자동차의 헤드 레스트에 일반적으로 사용되고 있는 것으로서, 전후방향으로 힘을 가하면, 전후방향으로 소정 거리만큼 이동하고 상하방향으로도 소정 거리만큼 이동하는 기능을 갖는다.       First, the upper tilt adjusting means 900d and the lower tilt adjusting means 800d are shown in cross-sectional view as seen from the front in FIG. 21, and the internal structure as seen from the right in FIG. The two tilt adjusting means 800d and 900d are generally used in the head rest of a vehicle. When the force is applied to the front and rear directions, the two tilt adjustment means 800d and 900d move the predetermined distance in the front and rear directions and the predetermined distance in the vertical direction. Have
이러한 기능을 갖는 상단 틸트 조절 수단(900d)은 하우징(901d)과 상기 하우징(901d)의 내측에 수용되는 회동 부재(902d) 및 스프링(905d)을 포함하여 이루어진다. 여기서 상기 회동 부재(902d)의 상단은 힌지 결합부 (903d)에 회동 가능하게 결합되며, 힌지 결합부(903d)와 하우징(901d)은 상기 상단 프레임(120d)의 측면 하부에 결합되고, 그 하단은 또 다른 힌지 결합부(904d)와 회동 가능하게 결합되며, 다른 힌지 결합부(904d)는 하단 프레임 (220d)의 측면 상부에 결합된다.       The upper tilt adjusting means 900d having this function includes a housing 901d and a rotation member 902d and a spring 905d accommodated inside the housing 901d. Here, the upper end of the rotation member 902d is rotatably coupled to the hinge coupling portion 903d, the hinge coupling portion 903d and the housing 901d are coupled to the lower side of the upper frame 120d, and the lower end thereof. Is rotatably coupled to another hinge coupling portion 904d, and the other hinge coupling portion 904d is coupled to the upper side of the lower frame 220d.
따라서 도19에서와 같이 상기 상단 틸트 조절 수단(900d)과 상기 하단 틸트 조절 수단(800d)이 상하로 정렬되어 있는 상태에서는, 상기 상단 틸트 조절 수단(900d)의 회동 부재(902d)가 도22의 좌측 그림에서와 같이 비스듬히 경사진 상태로 배치되지만, 상기 상단 프레임(120d)에 후방으로 힘을 가하면, 도22의 우측 그림에서와 같이 상기 회동부재(902d)가 상하로 수직하게 정렬되도록 회전하면서, 상기 상단 프레임(120d)이 후방으로 소정 거리만큼, 그리고 상방으로 소정 거리만큼 이동한다.       Therefore, as shown in FIG. 19, in the state where the upper tilt adjusting means 900d and the lower tilt adjusting means 800d are aligned up and down, the rotating member 902d of the upper tilt adjusting means 900d is shown in FIG. Although it is arranged in an inclined state as shown in the left figure, when applying a force to the upper frame (120d) to the rear, while rotating the rotating member 902d vertically aligned as shown in the right picture of Figure 22, The upper frame 120d moves backwards by a predetermined distance and upwards by a predetermined distance.
이러한 틸트 조절 수단(900d)의 내부 구성 및 원리는, 전술한 바와 같이, 현재 자동차의 헤드 레스트에 일반적으로 널리 사용되고 있는 것으로서, 본 실시예에서는 자동차에 일반적으로 사용되는 틸트 조절 수단의 구성 및 원리를 차용한 것이므로, 그 구성 및 작동 원리에 대한 더욱 자세한 설명은 생략한다.        As described above, the internal configuration and principle of the tilt adjustment means 900d are generally widely used for the head rest of the vehicle as described above. In this embodiment, the configuration and principle of the tilt adjustment means generally used in automobiles are described. Since it is borrowed, a more detailed description of its configuration and operation principle will be omitted.
그러나 본 실시예에서 사용하는 틸트 조절 수단(900d)의 내부 구성은 공지된 것이나, 본 실시예에 의하면, 틸트 조절 수단(900d)을 상단 프레임과 하단 프레임에 고정 설치 사용하여 상단 블록(100d)과 하단 블록(200d) 사이에서 틸트 조절이 가능하도록 함으로써, 상단 프레임의 전후 조절 동작을 통해 사용자의 뒤통수 형상에 따라 가장 편안하고 안정된 상태로 머리 받침구를 조절할 수 있게 된다. 틸트 조절 수단은 이미 널리 사용되어지는 기술이지만 머리받침을 상단과 하단으로 분리하여 두상을 조절하는데 틸트 조절 수단을 활용한 예는 아직 없는 것이다.       However, the internal configuration of the tilt adjustment means (900d) used in this embodiment is known, but according to this embodiment, by using the tilt adjustment means (900d) fixedly installed on the upper frame and the lower frame and the upper block (100d) By allowing tilt adjustment between the lower blocks 200d, the headrest can be adjusted in the most comfortable and stable state according to the shape of the user's back through the front and rear adjustment operation of the upper frame. Tilt adjustment means is a widely used technique, but there is no example of using the tilt adjustment means to control the head by separating the headrest to the top and bottom.
한편, 상기 하단 틸트 조절 수단(800d)은 상기 상단 틸트 조절 수단(900d)과 동일하게 하우징(801d)과 상기 하우징(801d)의 내측에 수용되는 회동 부재(802d) 및 스프링(805d)을 포함한다.       Meanwhile, the lower tilt adjusting means 800d includes a housing 801d and a rotation member 802d and a spring 805d that are accommodated inside the housing 801d, similarly to the upper tilt adjusting means 900d. .
여기서, 상기 회동 부재(802d)는 그 상단이 힌지 결합부(803d)를 통해 상기 하단 프레임(220d)의 측면 하단에 결합되고 그 하단은 각도 조절 수단 (700d)의 하우징에 결합된다. 따라서 상기 하단 프레임(220d)을 전방에서 후방쪽으로 밀어주면, 상기 회동 부재(802d)가 회전하면서, 상기 하단 프레임(220d)이 상방으로 소정 거리만큼 그리고 후방으로 소정 거리만큼 이동하므로 목덜미 형상에 적합하도록 조절이 가능하다.        Here, the rotating member 802d is coupled to the lower end of the side surface of the lower frame 220d through the hinge coupling portion 803d and the lower end is coupled to the housing of the angle adjusting means 700d. Therefore, when the lower frame 220d is pushed from the front to the rear, the pivot member 802d rotates so that the lower frame 220d moves upwards by a predetermined distance and backwards by a predetermined distance so that the lower frame 220d is suitable for the shape of the nape. Adjustable
여기서 상기 하단 틸트 조절 수단(800d)은 현재 자동차의 헤드 레스트에 일반적으로 사용되는 공지 기술을 차용한 것이므로, 이에 대한 자세한 설명은 생략한다. 본 실시예에서 사용하는 틸트 조절 수단(800d, 900d) 자체의 구성은 공지된 것이나, 본 실시예에 의하면, 틸트 조절 수단(800d, 900d)을 2개 사용하여 상단 블록(100d)과 하단 블록(200d) 사이에서도 틸트 조절이 추가로 가능하도록 함으로써, 사용자의 뒤통수 형상에 따라 가장 편안하고 안정된 상태로 머리 받침구를 조절할 수 있게 된다.        Here, since the lower tilt adjusting means 800d employs a known technique generally used for the head rest of the current vehicle, detailed description thereof will be omitted. The configuration of the tilt adjusting means (800d, 900d) itself used in this embodiment is known, but according to this embodiment, by using two tilt adjusting means (800d, 900d) the upper block (100d) and the lower block ( Tilt adjustment is possible even between the 200d), it is possible to adjust the headrest in the most comfortable and stable state according to the shape of the back of the user.
한편, 각도 조절 수단(700d)은 도21 및 도23에 그 구조가 도시되어 있는데, 도21에는 정면에서 바라본 단면도가 도시되어 있고, 도23의 우측에는 측면에서 바라본 모습이 도시되어 있으며, 도23의 좌측에는 하우징의 일부를 제거한 내부 구조가 도시되어 있다.       On the other hand, the angle adjustment means (700d) is shown in Figure 21 and 23, the structure is shown in Fig. 21 is a sectional view seen from the front, the right side of Fig. 23 is shown in a side view, Figure 23 On the left side is shown an internal structure with some of the housing removed.
상기 각도 조절 수단(700d)은, 하우징(701d)과, 상기 하우징(701d)의 내측에 형성된 수용부(702d)와, 상기 수용부(702d)에 수용된 톱니부(703d)와, 상기 톱니부(703d)의 하부에 배치되며 스위칭 레버(707d)의 조작에 연동하여 회전하는 모서리가 라운드진 대략 삼각형의 스위칭 부재(704d)와, 상기 스위칭 부재(704d)의 좌우 양측에 위치하는 2개의 스토퍼(705d)와, 상기 스토퍼(705d)를 상기 스위칭 부재(704d) 쪽으로 가압하는 스프링(706d)을 포함한다.       The angle adjusting means 700d includes a housing 701d, an accommodating portion 702d formed inside the housing 701d, a toothed portion 703d accommodated in the accommodating portion 702d, and the toothed portion ( 704d of a substantially triangular switching member having a rounded corner that is disposed below 703d and rotates in conjunction with the operation of the switching lever 707d, and two stoppers 705d positioned on both left and right sides of the switching member 704d. ) And a spring 706d for pressing the stopper 705d toward the switching member 704d.
상기 스프링(706d)은 일단이 상기 수용부(702d)의 벽면에 지지되고 타단이 상기 스토퍼(705d)에 지지되어 상기 스토퍼(705d)를 상시 상기 스위칭 부재(704d) 쪽으로 가압한다. 따라서, 상기 스토퍼(705d)가 상기 스위칭 부재(704d)의 모서리와 접촉하고 있을 때에는, 상기 스토퍼(705d) 와 상기 톱니부(703d)가 서로 이격되어 있게 되나, 상기 스위칭 부재 (704d)가 회전하여 모서리가 아니라 한 변이 상기 스토퍼(704d)와 접촉하는 경우에는 경사지게 배치되어 있던 상기 스토퍼(705d)가 수직하게 배치되므로 톱니부(703d)와 접촉하게 된다.        One end of the spring 706d is supported by the wall surface of the accommodation portion 702d and the other end is supported by the stopper 705d to press the stopper 705d toward the switching member 704d at all times.
