본 고안은 차량용 시트의 허리 지지장치에 관한 것이며, 특히 허리의 지지압 조절장치에 관한 것이다.The present invention relates to a waist support device for a vehicle seat, and more particularly, to a support pressure control device for the waist.
종래 시트의 허리 지지장치는 일본국 실용신안출원공고 평 4-15077에 기재된 바와 같이 프레임의 양측에 지지편을 부착하여 허리지지판이 부착된 토숀스프링을 회전할 수 있게 설치하고 일측 지지편에 핸들이 부착된 캠을 설치하여 토숀스프링에 형성된 캠접촉부를 승하강시키므로서 허리지지판이 전후방향으로 이동되어 허리의 지지압을 조절하고 있다.The waist support device of the conventional seat is attached to both sides of the frame as described in Japanese Utility Model Application Publication No. Hei 4-15077 so that the torsion spring with the waist support plate can be rotated, and the handle is attached to one support piece. By installing the attached cam to raise and lower the cam contact formed on the torsion spring, the back support plate is moved in the front and rear direction to adjust the support pressure of the waist.
그러나 상기 캠은 조절단이 3개에 불과하여 탑승자의 체형에 따라서 그 지지압이 부족한 경우가 생기며 허리의 압력에 의하여 캠접촉부에서 캠이 회전되어 조절된 지지압이 변하는 경우가 생기게 된다.However, since the cam has only three adjustment stages, the support pressure may be insufficient depending on the body shape of the occupant, and the adjusted support pressure may be changed by rotating the cam at the cam contact portion due to the pressure of the waist.
본 고안은 상기한 결점을 시정하여 허리지지압을 충분히 확보함과 동시에 조절된 지지압의 변동이 없는 차량용 시트의 허리 지지장치를 제공함을 목적으로 한다.The present invention aims to provide a lumbar support device for a vehicle seat without correcting the above-mentioned drawbacks to sufficiently secure the lumbar support pressure and at the same time adjusting the support pressure.
본 고안은 상기한 목적을 달성하기 위하여 프레임에 허리지지판이 부착된 토숀스프링의 지지부를 회전할 수 있게 설치하고 토숀스프링의 수평부 일단에 레버의 일단을 핀으로 연결함과 동시에 타단은 프레임에 부착된 조절구에 형성한 승강안내구에서 상하 이동하면서 걸림홈에 상하 이동하면서 걸리도록 한 것이다.The present invention is installed so as to rotate the support of the torsion spring attached to the waist support plate to the frame in order to achieve the above object, and the other end is attached to the frame while connecting one end of the lever to the horizontal end of the torsion spring While moving up and down in the elevating guide formed in the adjusting device is to be caught while moving up and down in the locking groove.
이하 실시예 도면에 의하여 설명한다.A description with reference to the following drawings.
본 고안은 제1도에 도시한 바와 같이 상하에 보강판(1')과 보강보(1'')이 형성되고 중앙부에 스프링(2)이 설치된 프레임(3)에 허리지지판(4)이 부착된 토숀스프링(5)의 지지부(6)(6')를 회전할 수 있도록 설치하고 토숀스프링(5)의 수평부 일단에 레버(7)의 일단을 핀으로 연결함과 동시에 타단은 프레임(3)에 부착된 조절구(8)에 형성한 승강안내구(9)에서 상하 이동하면서 승강안내구에 연통된 걸림홈(10)에 걸리도록 한 것이다.In the present invention, as shown in FIG. 1, the back support plate 4 is attached to the frame 3 having the reinforcement plate 1 'and the reinforcement beam 1' 'formed on the upper and lower sides and the spring 2 installed at the center thereof. The support part 6 (6 ') of the torsion spring 5 is rotated and one end of the lever 7 is pinned to one end of the horizontal part of the torsion spring 5, and the other end of the frame 3 While moving up and down in the elevating guide (9) formed in the control (8) attached to the) is to be caught in the locking groove (10) connected to the elevating guide.
미설명부호 11은 조절구(8)와 레버(7)의 타단에 연결된 스프링이고, 12는 손잡이이다.Reference numeral 11 is a spring connected to the other end of the adjusting device (8) and the lever (7), 12 is a handle.
이상과 같은 본 고안은 레버(7)의 타단이 조절구(8)의 걸림홈(10) 상부에 걸려 있을 때에는 허리지지판(4)은 제2도(a)와 같이 시트에서 돌출되지 않은 상태에 있으나 손잡이(12)를 허리지지판(4)측으로 밀면서 승강안내구(9)에서 하강시켜 점차로 걸림홈(10) 하단에 걸리게 하면 레버(7)가 토숀스프링(5)을 전방으로 밀므로서 레버지지판(4)이 시트에서 제2도 (b)와 같이 돌출되어 탑승자의 허리를 지지하면서 눌러주게 되고 탑승자가 허리에 힘을 가하더라도 레버(7)의 타단은 걸림홈(10)에 걸려 있으므로 항상 일정한 허리지지압을 유지하고 있다.The present invention as described above, when the other end of the lever 7 is caught in the upper portion of the locking groove 10 of the adjustment opening 8, the waist support plate 4 is in a state that does not protrude from the seat as shown in FIG. However, when the handle 12 is pushed toward the waist support plate 4 side and lowered from the lift guide 9 to gradually catch on the lower end of the locking groove 10, the lever 7 pushes the torsion spring 5 forward and the lever support plate (4) As shown in FIG. 2 (b), the seat protrudes from the seat while supporting the waist of the occupant and the other end of the lever 7 is caught in the locking groove 10 even when the occupant applies the waist. Maintaining back support pressure.
이상과 같이 본 고안은 토숀스프링을 조절구의 걸림홈에 걸리게 되는 레버에 의하여 전방으로 밀게 하였으므로 허리가 많이 들어간 체형의 탑승자라 할지라도 그 지지압이 부족함이 없이 충분히 확보되어 편안한 자세에서 운전을 할 수 있고 또한 일단 조절된 허리지지압은 탑승자가 시트방향으로 허리에 시트 방향으로 힘을 가하더라도 변동되지 않고 항상 일정한 지지압을 유지할 수 있는 등의 효과가 있다.As described above, the present invention pushes the torsion spring forward by the lever that is caught by the locking groove of the adjusting mechanism, so even a passenger with a lot of waists is sufficiently secured without lack of support pressure and can drive in a comfortable posture. In addition, once the waist support pressure is adjusted, there is an effect such that the occupant can maintain a constant support pressure at all times without fluctuation even when a force is applied to the waist in the seat direction.
