본 고안은 자동차용 시트의 룸바 서포트(LUMBAR SUPPORT) 장치에 관한 것으로, 보다 상세하게는 장시간 차량운전시에 운전자의 피로감을 줄여주고 바른 자세를 유지시키도록 하여 안전한 운전을 도모할 수 있도록 한 자동차용 시트의 룸바 서포트 장치에 관한 것이다.The present invention relates to a LUMBAR SUPPORT device of an automobile seat, and more particularly, to reduce driver fatigue and maintain a correct posture when driving a vehicle for a long time. It relates to a room bar support apparatus of a sheet.

일반적으로 자동차용 시트의 룸바 서포트 장치는 제1도에서 보는 바와 같이 시트백(SEAT BACK)에 설치되는 것으로 운전자의 요부에 작용하여 운전자에게 안락성을 주어 피로도를 덜어 주도록 한 것이다.In general, as shown in FIG. 1, a room bar support device of an automobile seat is installed in a seat back to act on the driver's main part, thereby providing comfort to the driver and reducing fatigue.

상기와 같은 작용을 하는 종래의 자동차용 시트의 룸바 서포트 장치는 제2도에서 보는 바와 같이 축(6)을 회전시키면 스프링지지핀(8)이 토션 스프링(TORSION SPRING : 4)에 작용하여 토션 스프링력이 룸바 서포트 플레이트(LUM BAR SUPPORT PLATE : 2)를 앞으로 밀고 나가 운전자의 허리를 받쳐주는 역할을 한다.As shown in FIG. 2, when the shaft 6 is rotated, the spring support pin 8 acts on the torsion spring 4 and the torsion spring 4 as shown in FIG. The force pushes the RUM BAR SUPPORT PLATE (2) forward to support the driver's waist.

이와 같이 작용하는 종래의 것은 룸바 서포트 플레이트면이 평면이므로 운전자의 요부 굴곡에 시트백 부분이 평면적으로 전해져 안락한 시트의 요구조건을 만족시키지 못해 피로감이 쌓이는 등의 문제점이 있어 왔다.The conventional method that acts as described above has a problem that, since the surface of the room bar support plate is flat, the seat back portion is transmitted flat to the driver's bent portion, thereby failing to satisfy the requirements of the comfortable seat, and the fatigue builds up.

본 고안은 상기한 문제점을 감안하여 안출한 것으로, 운전자가 장시간동안 자동차의 운전을 할 경우에 운전자에게서 피로감을 덜어 주어 편안하게 함과 동시에 바른 자세를 유지시키도록 하기 위한 목적으로 고안된 것이다.The present invention is conceived in view of the above problems, it is designed for the purpose of maintaining a correct posture while reducing the fatigue from the driver when the driver is driving the car for a long time.

본 고안은 상기의 목적을 달성하기 위하여 시트의 룸바 서포트 회전축의 끝단에 나사부를 만들어 브래킷이 나사산을 따라 이동하게 함으로서 브래킷에 고정된 룸바 서포트 판넬이 곡면을 만들어 운전자의 허리의 굴곡에 확실하게 지지시켜 주도록 한 것이다.In order to achieve the above object, the present invention makes a threaded portion at the end of the Rumba support shaft of the seat to move the bracket along the thread so that the Rumba support panel fixed to the bracket creates a curved surface so as to be firmly supported by the bending of the driver's waist. It was given.

이하 첨부된 도면을 통하여 본 고안의 마람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 구성을 제3도 및 제4도에서 보면, 시트백(SEAT BACK)의 백프레임(SACK FRAME : 50)상의 대향하는 양측으로 축지지브래킷(58)을 고정 설치하고, 세개의 판스프링(64)중 두개는 가장자리에 위치시키며 다른 하나는 양끝단에 고정장공(70)을 형성하여 중간에 위치시키고 다수개의 스프링 연결판(66)으로 상기의 판스프링(64)들을 고정공(68)을 통하여 리벳이나 용접등의 수단으로 체결 고정하여 이루어진 룸바 서포트 판넬(54)을 슬립홈(80)을 갖는 고정볼트(78)로 룸바 서포트 판넬(54)의 고정장공(70)에 삽입하여 경사면(76)을 갖는 판넬 고정브래킷(56)의 볼트삽입홈(74)에 체결 고정하고, 임의의 적당한 길이로 나사부(60)가 형성되어진 중공된 회전축(52)에 판넬고정브래킷(56)의 나사부 형성 축삽입공(72')을 삽입 설치하고 회전축(52)의 다른단은 축삽입공(72)이 있는 판넬고정브래킷(56)을 삽입 고정한 다음 상기 나사부(60)의 양단에 형성된 스냅링 체결홈(84)에 스냅링(82)을 체결하고 회전축(52)의 양단을 축지지브랫킷(58)의 축삽입공(72)에 삽입지지하며 회전축(52)의 한단은 룸바 서포트 조절핸드(62)을 설치하고 다른단은 부쉬(Bush: 86)를 끼워 고정하여 구성됨을 특징으로 한다.3 and 4, the shaft support brackets 58 are fixedly installed at opposite sides on the back frame SACK FRAME 50 of the seat back, and three leaf springs ( Two of the 64 is positioned at the edge and the other is formed in the middle of the fixing hole (70) at both ends and a plurality of spring connecting plate 66 to the plate springs 64 to the fixing hole 68 Rumba support panel 54 formed by fastening and fixing by means of riveting or welding through the fixing bolt 78 having slip grooves 80 is inserted into the fixing holes 70 of the Rumba support panel 54 and the inclined surface 76 The screw forming shaft of the panel fixing bracket 56 is fastened to the bolt insertion groove 74 of the panel fixing bracket 56 having an inner side of the panel fixing bracket 56 on the hollow rotating shaft 52 in which the threaded portion 60 is formed at any suitable length. Insertion hole 72 'is installed and the other end of the rotary shaft 52 is the shaft insertion hole 72 After inserting and fixing the nel fixing bracket 56, the snap ring 82 is fastened to the snap ring fastening groove 84 formed at both ends of the screw part 60, and both ends of the rotation shaft 52 are inserted into the shaft support bracket 58. The ball 72 is inserted and supported, and one end of the rotation shaft 52 is installed by installing the Rumba support adjustment hand 62 and the other end by inserting and fixing a bush 86.

상기와 같이 구성되는 본 고안의 작용효과를 제5도에서 보면 회전축(52)의 한쪽단에만 나사부(60)를 형성한 것으로 도면에 도시된 회전방향으로 룸바서포트 조절핸들(62)을 돌리면 나사부 형성 축삽입공(72')을 갖는 판넬고정브래킷(56)이 회전축(52)의 나사부(60)에 형성된 수나사산을 따라 이동하며, 다른 쪽 판넬고정브래킷(56)은 회전축(52)상에 기립상태로 되고, 회전축(52)의 회전량만큼 나사부(60)상의 판넬고정브래킷(56)이 이동하여 판넬고정브래킷(56)에 고정되어진 룸바서포트판넬(62)이 곡면을 만들어 운전자의 요부굴곡에 알맞게 함으로서 운전자의 허리를 확실하게 밀착시켜 지지시켜 줄 수 있는 것이다.Referring to FIG. 5, the screw 60 is formed only at one end of the rotating shaft 52, and when the room bar support adjusting handle 62 is turned in the rotational direction shown in the drawing, the screw is formed. The panel fixing bracket 56 having the shaft insertion hole 72 'moves along the male thread formed in the threaded portion 60 of the rotating shaft 52, and the other panel fixing bracket 56 stands on the rotating shaft 52. The panel fixing bracket 56 on the threaded portion 60 is moved by the amount of rotation of the rotary shaft 52, and the room bar support panel 62 fixed to the panel fixing bracket 56 forms a curved surface to form the recessed part of the driver. By making it fit properly, the driver's waist can be firmly held and supported.

상기와 같이 작용할때, 판넬고정브래킷(56)의 경사면(76)과 고정볼트(78)의 슬립홈(80)은 룸바서포트판넬(54)이 곡면을 형성할때 원할하게 작동할 수 있도록 한 것이다.When acting as described above, the inclined surface 76 of the panel fixing bracket 56 and the slip groove 80 of the fixing bolt 78 is to enable the room bar support panel 54 to operate smoothly when forming the curved surface. .

제6도는 본 고안의 다른 실시예로서 회전축(52)의 양쪽단으로 나사부(60)를 형성한 것으로, 상기의 실시예와 같은 방법으로 룸바서포트 조절핸들(62)을 돌림으로서 회전축(52)이 회전하여 각각 다른 방향으로 형성되어진 나사산을 따라 좌우에서 판넬고정브래킷(56)이 안쪽으로 이동하여 회전축이 회전한량 만큼의 이동량을 얻어 룸바서포트판넬(54)은 운전자의 요부에 알맞는 곡률의 곡면을 얻어 운전자의 허리를 지지시켜 주는 것이다.FIG. 6 is a view showing another embodiment of the present invention, in which threads 60 are formed at both ends of the rotation shaft 52, and the rotation shaft 52 is rotated by turning the room bar support adjusting handle 62 in the same manner as the above embodiment. The panel fixing brackets 56 are moved inward from the left and right along the threads formed in different directions by rotation to obtain the movement amount as much as the rotation axis is rotated, so that the Rumba Support Panel 54 provides a curved surface suitable for the driver's main part. To support the driver's waist.

상기와 같이 작용하는 본 고안은 룸바서포트판넬이 곡면을 형성할 수 있도록 함으로서 시트 백이 확실한 서포트를 제공하도록 하여 운전자의 허리를 확실하게 받쳐줌으로서 장시간 운전시에도 운전자의 피로감을 줄여주고 바른자세를 유지시킬 수 있는 등의 효과를 갖는 매우 실용적인 고안이다.The present invention acting as described above allows the room back support panel to form a curved surface so that the seat back provides a definite support, thereby firmly supporting the driver's waist, thereby reducing fatigue and maintaining a correct posture for a long time. It is a very practical design with the effect of being able to make.
