Description

자동차용 시트벨트 커팅장치{Device for cutting seatbelt for automobile}Seat belt cutting device for automobiles {Device for cutting seatbelt for automobile}

본 발명은 자동차용 시트벨트 커팅장치에 관한 것으로서, 더욱 상세하게는 차량의 사고와 동시에 착용하고 있던 시트벨트에 의하여 완충을 받는 동시에 시트벨트가 자동으로 절단되도록 하여, 시트벨트에 의한 압박감을 해소하는 동시에 부상 승객을 외부로 용이하게 이송할 수 있도록 한 자동차용 시트벨트 커팅장치에 관한 것이다.The present invention relates to a seat belt cutting device for automobiles, and more particularly, the seat belt is automatically cut at the same time as the seat belt is worn at the same time as the accident of the vehicle, and the seat belt is automatically cut, thereby eliminating the feeling of pressure caused by the seat belt. At the same time, the present invention relates to a seat belt cutting device for an automobile that can easily transport an injured passenger to the outside.

통상적으로 자동차의 충돌 사고시, 실내에 승차하고 있는 승객은 시트벨트에 의하여 전방 쏠림을 구속받으며 상해치를 크게 줄일 수 있다.In general, in the event of a car crash, passengers who ride in the cabin are restrained by the front belt by the seat belt and can greatly reduce the injuries.

이때, 상기 시트벨트에 의한 전방 쏠림을 완충받은 후, 부상승객이 계속 시트벨트를 착용하고 있는 상태에서는 그 압박감으로 인하여 제2의 상해를 입을 수 있는 바, 압박감을 해소시켜주기 위하여 빨리 시트벨트를 풀어주어야 하고, 또한 부상승객을 차외부로 이송할 경우에도 시트벨트를 풀어주어야 하기 마련이다.At this time, after the frontal pull by the seat belt is fully buffered, the second passenger may be injured due to the pressure while the injured passenger continues to wear the seat belt, so that the seat belt can be quickly removed to relieve the pressure. In addition, the seat belts must be released when transporting injured passengers out of the car.

그러나, 자동차의 사고시 충격으로 시트벨트의 버클등이 파손된 경우 시트벨트가 풀리지 않을 수 있고, 사고시간이 많이 지난 후 임의적인 커팅수단으로 시트벨트를 커팅함으로써, 사고후 시트벨트에 의한 제2상해를 그대로 입게 되는 단점이 있다.However, when the buckle of the seat belt is damaged due to the impact of the car accident, the seat belt may not be released, and after a long time of accident, the seat belt is cut by arbitrary cutting means, thereby causing a second injury due to the seat belt after the accident. There is a disadvantage of wearing it as it is.

따라서, 본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 프리텐셔너로부터 도출되어 있는 시트벨트의 양편에 커팅수단을 설치하고, 이 커팅수단을 이동시킬 수 있도록 볼을 포함하는 점화장치를 설치하여, 충돌 사고시 에어백이 폭발한 후, 수초후 상기 점화장치의 폭발로 볼이 발사됨과 동시에 볼이 커팅수단을 이동시킴으로써, 시트벨트가 커팅수단에 의하여 자동으로 커팅되어, 시트벨트의 압박에 의한 2차 상해를 줄일 수 있도록 한 자동차용 시트벨트 커팅장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above point, by providing cutting means on both sides of the seat belt drawn from the pretensioner, by installing an ignition device including a ball to move the cutting means, In the event of a crash, after the airbag explodes, a few seconds later, the ball is fired by the explosion of the ignition device and the ball moves the cutting means, so that the seat belt is automatically cut by the cutting means, thereby causing secondary injury due to the pressing of the seat belt. It is an object of the present invention to provide a seat belt cutting device for an automobile so as to reduce the weight of the vehicle.

It features.

또한, 상기 경로파이프(16)의 반대쪽에는 볼(14)이 수납되는 수납통(26)이 장착된다.In addition, on the opposite side of the passage pipe 16, a housing 26 for receiving the ball 14 is mounted.

여기서 본 발명을 실시예로서, 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Herein, the present invention will be described in more detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 자동차용 시트벨트 커팅장치를 나타내는 단면도로서, 도면부호 24는 커터 케이스이다.1 is a cross-sectional view showing a seat belt cutting device for automobiles according to the present invention, and reference numeral 24 denotes a cutter case.

상기 커터 케이스(24)는 프레텐셔너(10)가 장착된 하우징(28)의 상부에 시트벨트(20)를 사이에 두고 서로 마주보게 장착된다.The cutter case 24 is mounted to face each other with the seat belt 20 interposed therebetween on the housing 28 on which the pretensioner 10 is mounted.

또한, 상기 커터 케이스(24)에는 날카로운 끝단이 서로 마주보게 커터(18)가 내재되어 있고, 이 커터(18)의 상부면에는 탄성의 밀림단(22)이 일체로 형성되어 있는 바, 탄성의 밀림단(22)이 좌우로 슬라이드되도록 상기 커터 케이스(24)의 일면에는 홈이 형성되어 있다.In addition, the cutter case 24 has a cutter 18 inherent so that sharp ends face each other, and an elastic push end 22 is integrally formed on the upper surface of the cutter 18. A groove is formed on one surface of the cutter case 24 so that the slide end 22 slides from side to side.

즉, 커터(18)의 날카로운 부분이 시트벨트(20)를 사이에 두고 위치하고 있고, 탄성 밀림단(22)이 밀리는 동시에 커터(18)가 상기 커터 케이스(24)의 홈을 따라 이동하여 시트벨트(20)를 자르게 된다.That is, the sharp part of the cutter 18 is positioned with the seat belt 20 interposed therebetween, and the elastic jungle end 22 is pushed and the cutter 18 moves along the groove of the cutter case 24 so that the seat belt 20 can be moved. Cut 20.

특히, 상기 커터 케이스(24)의 일면에는 상기 탄성의 밀림단(22)을 밀어줄 수 있는 볼(14)의 경유로 역할을 하는 경로파이프(16)가 설치되는 바, 이 경로파이프(16)의 일측끝에는 볼(14)이 내재된 점화장치(12)가 설치되고, 반대측끝에는 볼(14)이 수납되는 수납통(26)이 설치되어 있다.Particularly, one surface of the cutter case 24 is provided with a path pipe 16 serving as a passage of the ball 14 capable of pushing the elastic jungle end 22, and the path pipe 16 is provided. At one end of the ignition device (12) is built in the ball 14 is installed, the opposite end is provided with a receiving cylinder 26 for receiving the ball (14).

한편, 상기 점화장치(12)에는 전자제어장치와 연결되어 있는 바, 에어백의 폭발후 수초후에 전자제어장치는 점화장치(12)에 폭발 전류신호를 보내게 된다.On the other hand, the ignition device 12 is connected to the electronic control device, a few seconds after the explosion of the airbag electronic control device sends an explosion current signal to the ignition device 12.

여기서 본 발명의 작동상태를 첨부한 도 2a,2b를 참조로 상세하게 설명한다.It will be described in detail with reference to Figures 2a, 2b attached to the operating state of the present invention.

자동차의 충돌 사고로 에어백이 폭발한 경우, 수초후에 전자제어장치는 점화장치에 전류신호를 보내어, 점화장치가 폭발하게 된다.If the airbag explodes due to a car crash, a few seconds later, the electronic control unit sends a current signal to the ignition device, causing the ignition device to explode.

상기 점화장치(12)의 폭발압에 의하여 볼(14)이 경로파이프(16)를 따라 이동하면서 커터(18)의 탄성 밀림단(22)을 밀게 된다.Due to the explosion pressure of the ignition device 12, the ball 14 moves along the path pipe 16 and pushes the elastic push end 22 of the cutter 18.

따라서, 커터(18)가 이동하면서 상기 시트벨트(20)를 절단하게 됨으로써, 시트벨트(20)의 완충을 받았지만 계속해서 압박을 받으며 착용하고 있던 승객의 시트벨트(20)가 용이하게 풀리게 되어, 승객의 상해치를 줄일 수 있다.Thus, by cutting the seat belt 20 while the cutter 18 moves, the seat belt 20 of the passenger who has been fully cushioned by the seat belt 20 but continues to be pressed is easily released. Injury of passengers can be reduced.

한편, 상기 탄성 밀림단(22)을 밀면서 이동한 볼(14)은 수납통(26)에 수납되어진다.On the other hand, the ball 14 moved while pushing the elastic jungle end 22 is accommodated in the storage container (26).

이상에서 본 바와 같이, 본 발명에 따른 자동차용 시트벨트 커팅장치에 의하면, 에어백의 폭발 후 수초후에 시트벨트를 자동으로 절단시켜줌으로써, 자동차의 충돌시 시트벨트의 완충을 받은 후, 계속되는 시트벨트의 압박감을 제거하여 승객의 상해를 줄일 수 있는 장점이 있다.As described above, according to the automobile seat belt cutting apparatus according to the present invention, by automatically cutting the seat belt after a few seconds after the explosion of the air bag, after receiving the cushion of the seat belt during the collision of the car, There is an advantage to reduce the passenger injuries by eliminating the feeling of pressure.
