Description
본 발명은 차량용 시트 벨트에 관한 것으로, 특히 차량에 큰 가감속도가 가해진 경우에 벨트를 로크하도록 된 시트 벨트의 긴급 권취장치(emergency winding device of seat belt for automobile)에 관한 것이다.TECHNICAL FIELD The present invention relates to a seat belt for a vehicle, and more particularly to an emergency winding device of a seat belt for automobile, in which a belt is locked when a large acceleration / deceleration is applied to the vehicle.
차량에 이용되는 시트 벨트는 자동차가 충돌되는 경우 탑승자를 본래의 위치에 억제시켜 상해 정도를 감소시키기 위해 사용되는 안전장치로서, 허리를 구속하는 랩 벨트(허리 벨트)와 상체를 구속하는 숄더 벨트(가슴 벨트)를 조합한 3점식 시트 벨트가 널리 이용된다.Seat belts used in the vehicle are safety devices used to reduce the degree of injury by restraining the occupants to their original positions in the event of a vehicle collision. A three-point seat belt in combination with a chest belt is widely used.
상기한 시트 벨트에는 로드 리미터가 설치되며, 로드 리미터는 충돌시 벨트 착용자에 대한 시트 벨트의 압박 정도를 감소시켜 흉부 손상을 방지하게 되는 주용한 기능을 수행하며, 벨트를 풀었을 때 자동적으로 감겨지는 리트랙터가 또한 설치된다. 그리고, 상기한 벨트를 감는 장치인 리트랙터는 통상적으로 프런트 시트 벨트에 설치되어 있으며 비 로크식 감는 장치(non locking retractor)와 긴급 로크식 감는 장치(emergency locking retractor)의 2가지 종류가 있다. 이러한 어느 장치도 3점식 시트 벨트의 장착을 용이하게 하기 위한 것으로 비 로크식 감는 장치는 가슴,허리 벨트의 길이를 조정한 상태로 로크되는데 비하여 긴급 로크식 장치는 정차중 또는 보통 주행중에 벨트는 자유로이 신축할 수 있으나, 충돌시 등 차량에 큰 감속도가 가해진 경우나 벨트의 인출 가속도가 큰 경우에 벨트를 로크하도록 되어 있다.The seat belt is provided with a load limiter, and the load limiter performs a main function of reducing the pressure of the seat belt against the belt wearer in the event of a collision to prevent chest damage, and is automatically wound when the belt is released. Retractors are also installed. The retractor, which is a device for winding the belt, is usually installed in the front seat belt, and there are two types of non-locking retractors and emergency locking retractors. All of these devices are designed to facilitate the installation of three-point seat belts. The non-locking type winding device is locked with the length of the chest and waist belt adjusted, whereas the emergency locking type device is freely stopped during normal or normal driving. Although it can expand and contract, the belt is locked when a large deceleration is applied to the vehicle, such as in a collision, or when the withdrawal acceleration of the belt is large.
그러나, 상기와 같은 종래 기술에 따른 구성에 의하면, 차량 충돌시 스풀 아웃(spool out)현상이 발생되므로 탑승자의 상부가 전방으로 쏠리게된다. 따라서, 스티어링 휠에 운전자의 가슴과 머리가 충돌되어 탑승자의 상해치가 가중되는 문제점이 발생된다.However, according to the configuration according to the prior art as described above, the spool out phenomenon occurs during the vehicle collision, so that the upper part of the occupant is tilted forward. Therefore, the driver's chest and head collide with the steering wheel, thereby causing a problem that the injury value of the occupant is increased.
본 발명은 상기와 같이 종래 기술에 내재되었던 문제점을 해결하고자 창안된 것으로, 본 발명의 목적은 작약과 압축스프링을 이용한 실린더부재를 사용하여 차량 충돌시 신속하고 용이하게 벨트의 인출을 저지시켜 탑승자의 상해치를 가감 시키는 시트 벨트의 긴급 권취장치를 제공하는데 있다.The present invention has been made to solve the problems inherent in the prior art as described above, an object of the present invention by using a cylinder member using a peony and compression spring to quickly and easily prevent the withdrawal of the belt during a vehicle crash The present invention provides an emergency winding device for a seat belt to reduce or reduce an injury value.

본 발명에 의한 시트 벨트 긴급 권취장치는 도 1 에 도시한 것처럼 시트 쿠션(42)과 시트 백(44)의 연결부의 측면에 위치한 필러 트림(20)에 장착되며, 충격 감지센서(40), ECU(38), 실린더 부재(10) 등을 포함한다.The seat belt emergency winding apparatus according to the present invention is mounted on the filler trim 20 located on the side of the connection portion between the seat cushion 42 and the seat back 44, as shown in FIG. 38, the cylinder member 10, and the like.
상기 실린더 부재(10)는 도 2 처럼 상기 필러 트림(20)내에서 시트 벨트 리트랙터(16)가 설치된 장착 브래킷(18)의 상부에 고정 브래킷(22)으로 고정되며, 상기 ECU(38)와 연결되어 차량의 충돌을 감지하는 상기 충격 감지센서(40)의 신호에 따라 상기 ECU(38)의 지령을 받아 작동 된다.The cylinder member 10 is fixed to the upper part of the mounting bracket 18 in which the seat belt retractor 16 is installed in the filler trim 20 as shown in FIG. It is connected to the command of the ECU 38 in response to the signal of the impact sensor 40 for detecting a collision of the vehicle is operated.
또한, 상기 실린더 부재(10)는 케이스(24), 피스톤(12), 로드(26), 제 1 및 제 2 롤러(30,32), 작약(36), 압축 스프링(14), 커버(34)를 포함하며, 상기 케이스(24)는 상단부가 개방된 원통형이다.In addition, the cylinder member 10 includes a case 24, a piston 12, a rod 26, first and second rollers 30 and 32, peony 36, a compression spring 14, and a cover 34. ), The case 24 is cylindrical with an open top.
상기 로드(26)는 일단부가 상기 케이스(24)내의 피스톤(12)과 연결되고, 타단부에는 제 1 롤러(30)가 회전가능하게 장착되며, 상기 제 2 롤러(32)는 초기상태에서 상기 리트랙터(16)에서 인출된 벨트(28)와 연결된 상기 제 1 롤러(30)와 인접하여 상기 벨트(28)를 연속하여 감는다. 상기 압축 스프링(14)은 상기 케이스(24)의 저부에 안착되고, 상기 작약(36)은 상기 ECU(38)와 연결되어 상기 압축 스프링(14) 상부에 위치하며, 상기 작약(36)의 폭발로 파열되는 상기 커버(34)는 상기 작약(36)과 상기 피스톤(12) 사이에 설치된다.One end of the rod 26 is connected to the piston 12 in the case 24, and the other end thereof is rotatably mounted with a first roller 30, and the second roller 32 is in the initial state. The belt 28 is continuously wound adjacent to the first roller 30 connected to the belt 28 drawn out of the retractor 16. The compression spring 14 is seated at the bottom of the case 24, the peony 36 is connected to the ECU 38 and is located above the compression spring 14, the explosion of the peony 36 The cover 34, which is ruptured in, is installed between the peony 36 and the piston 12.
본 발명의 상기와 같은 구성에 의해, 차량 충돌시 상기 충격 감지 센서(40)에 의한 상기 ECU(38)의 작동으로 상기 작약(36)은 폭발하고 상기 커버(34)는 파열된다. 따라서 상기 압축 스프링(14)의 힘으로 상기 실린더 부재(10)의 피스톤(12)은 상향으로 이동되므로, 상기 피스톤(12)에 연결된 상기 로드(26)의 상기 제 1 롤러(30)는 벨트(28)와 함께 수직 상승하므로 상기 벨트(28)의 인출은 신속하게 저지된다.With the above configuration of the present invention, the charge 36 is exploded and the cover 34 is ruptured by the operation of the ECU 38 by the impact sensor 40 in a vehicle crash. Accordingly, since the piston 12 of the cylinder member 10 is moved upward by the force of the compression spring 14, the first roller 30 of the rod 26 connected to the piston 12 is a belt ( As it rises vertically with 28, the withdrawal of the belt 28 is quickly stopped.
본 발명의 상기와 같은 구성 및 작용에 따라, 차량의 충돌시 신속하고 용이하게 벨트의 인출은 저지되어 스풀 아웃현상이 방지되므로 스티어링 휠에 운전자의 가슴과 머리가 충돌되는 탑승자의 상해치는 가감 된다.According to the above-described configuration and operation of the present invention, the withdrawal of the belt is prevented quickly and easily during the collision of the vehicle to prevent the spool out phenomenon, so that the injury value of the occupant of the driver's chest and head collided with the steering wheel is added or subtracted.
본 발명을 특정의 바람직한 실시예에 관련하여 도시하고 설명하였지만, 이하의 특허청구의 범위에 의해 마련되는 본 발명의 정신이나 분야를 이탈하지 않는 한도내에서 본 발명이 다양하게 개조 및 변회될 수 있다는 것을 당 업계에서 통상의 지식을 가진 자는 용이하게 알 수 있다.While the invention has been illustrated and described with reference to certain preferred embodiments, it will be understood that the invention can be modified and modified in various ways without departing from the spirit or the scope of the invention as set forth in the following claims.
