Abstract

A webbing retractor is provided to maintain load exerted on passenger constant by reducing the length of a webbing retracted after a pretensioner mechanism is activated. In a webbing retractor, An inner cover(4) and a plate cover(6) are equipped in one side of a frame(1) of a pretensioner. The pressure of gas of a gas generator is delivered to a power transmission part with a pressure transmission part of a cylinder. A pinion meshed with the power transmission is rotated. A base lock connected to the pinion is rotated and winds webbing. A lock pawl is engaged with the base lock and stalls it in case of over specific acceleration. The lock pawl is installed in an inner cover by a screw(3). A stopper pin(5) breaks a connection part with the lock pawl depending on the activation of a pinion and a power transmission part. The pawl spring(8) pushes the lock pawl of the fractured connection part to a base lock of the lock pawl in case of specific acceleration. The pawl spring is connected to a holder sensor(7).

웨빙권치장치{WEBBING RETRACTOR}Webbing Towing Device {WEBBING RETRACTOR}

본 발명은 웨빙권치장치의 하중 유지구조에 관한 것으로, 좀더 상세하게는 승객의 구속력을 증대시키기 위하여 프리텐셔너 기구의 작동 후에 웨빙으로부터 승무원에게 작용하는 하중을 거의 일정하게 할 수 있는 웨빙권치장치의 하중 유지장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load holding structure of a webbing disposition device, and more particularly, to a load holding device of a webbing disposition device capable of substantially constant a load acting on the crew from the webbing after the operation of the pretensioner mechanism in order to increase the binding force of the passenger. Relates to a device.

본 발명의 종래기술로는 도 1에서 도시한 바와 같이 대한민국 특허출원 10-2006-7021904호로서, 웨빙 권취 장치(10)에서는 락 파울(78)이 락 기어(26)에 서로 맞물릴 수 없는 상호간 맞물림이 불능한 상태로 되어 있으며, 프리텐셔너 기구(34)가 작동하여 클러치 플레이트(42)가 권취 방향으로 회전하였을 경우에 락 스토퍼(86)가 클러치 플레이트(42)와 함께 회전하여 락 파울(78)과의 계합을 해제하기 때문에 락 파울(78)이 압축 코일 스프링(70)에 의하여 회동하여 상호간 맞물림이 가능한 상태로 변경되고, 이로 인하여 프리텐셔너 기구(34)의 작동 후에 승무원으로부터 하중에 의하여 락 기어(26)에 인출 방향으로 회전력이 부여된 직후에는 락 파울(78)이 락 기어(26)에 서로 맞물려서 웨빙(20)의 인출이 저지되어 인출되는 웨빙(20)의 양을 줄일 수 있게 한다는 구성이 있었으며, 프리텐셔너 기구의 작동 후 에 웨빙으로부터 승무원에게 작용하는 하중을 거의 일정하게 유지하게 한다는 목적을 가지고 있었다.In the prior art of the present invention, as shown in Figure 1, the Republic of Korea Patent Application No. 10-2006-7021904, in the webbing take-up device 10, the lock foul 78 can not be engaged with each other in the lock gear (26) The lock stopper 86 rotates together with the clutch plate 42 when the pretensioner mechanism 34 is operated to rotate the clutch plate 42 in the winding direction when the pretensioner mechanism 34 is in an engaged state. Since the lock foul 78 is rotated by the compression coil spring 70 so as to be engaged with each other, the lock foul 78 is released by the crew after operation of the pretensioner mechanism 34. Immediately after the rotational force is applied to the drawing direction 26, the lock foul 78 is engaged with the lock gear 26 so that the drawing of the webbing 20 is prevented to reduce the amount of the webbing 20 drawn out. There It was, had the purpose of keeping substantially constant the load applied to the crew from the webbing after operation of the pretensioner mechanism.

그러나 상기 종래기술의 프리텐셔너 메커니즘에서는 긴급잠금장치가 프리텐셔너 작동 종단부 이후에 작동하기 때문에 불필요하게 웨빙이 인출되어 승객에게 작용하는 하중이 순간적으로 드롭다운(DROP DOWN) 된다는 문제가 있었다.However, the pretensioner mechanism of the prior art has a problem that the emergency locking device operates after the pretensioner operating end, so that the webbing is unnecessarily drawn and the load acting on the passenger is dropped immediately (DROP DOWN).

본 발명은 상기의 문제점을 해결하기 위한 것으로, 상세하게는 승객의 구속력을 증대시키기 위하여 프리텐셔너 기구의 작동 후에 웨빙으로부터 승무원에게 작용하는 하중을 거의 일정하게 할 수 있는 웨빙권치장치의 하중 유지하는 구조를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and in particular, in order to increase the restraint of the passenger, a load retaining structure of the webbing disposition device capable of substantially constant the load acting from the webbing to the crew after operation of the pretensioner mechanism is provided. The purpose is to provide.
