Description
본 발명은 차량용 시트의 안전장치에 관한 것으로써, 특히 차량의 정면 충돌사고시 앞좌석의 시트가 후방으로 후진됨과 아울러 회전되도록 한 차량용 시트의 안전장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for a vehicle seat, and more particularly to a safety device for a vehicle seat in which a seat of the front seat is reversed and rotated in a front collision of the vehicle.
일반적으로, 차량에 채용되는 안전장치로는 에어백이 마련되어 있으며, 이 에어백은 충돌사고시 주행중의 관성력에 의해서 탑승객이 전방으로 쏠리게 되어 탑승객의 머리 또는 흉부가 차체 또는 전면 윈도우글래스에 부딪히는 것을 방지하는 기능을 갖는다.In general, a safety device employed in a vehicle is provided with an airbag, which prevents the occupant's head or chest from hitting the vehicle body or the front window glass by the inertia force while driving in an accident. Have
그러나, 상기한 유용한 기능을 갖는 에어백은 충돌시 작은 충격력이 전달될 경우에는 탁월한 효과를 가지게 되지만, 이와 상반되는 큰 충격력이 전달될 때는 엔진이 실내로 밀리게 되어 탑승객에게 직접적으로 부딪히는 경우에는 승객보호기능을 수행하지 못하는 문제점이 있다.However, the airbag having the above useful functions has an excellent effect when a small impact force is transmitted in a collision, but when the large impact force is transmitted to the contrary, the engine is pushed into the room to protect passengers when directly hit the passengers. There is a problem that does not function.
물론, 상기한 문제점을 해결하고자 종래에는 차량의 엔진룸측으로 크로스 멤버 및 론지튜디널프레임 등의 보강재를 설치하거나, 전면에 에너지 흡수기능이 향상된 범퍼를 설치하는 등의 충돌사고시 충격력을 최소화하려는 여러 가지 방안이 채택되었다.Of course, in order to solve the above problems, in order to minimize the impact in the event of a crash, such as installing a reinforcement such as a cross member and a longi frame to the engine room side of the vehicle, or installing a bumper with improved energy absorption in the front The plan was adopted.
그러나, 이러한 차량의 충돌사고시 엔진이 실내로 밀리게 됨에 따라 탑승객의 몸체가 엔진과 시트사이에 끼이게 되는 경우가 발생되고, 이로 인해 부상자의 병원으로의 이송이 지연되어 심지어는 사망에 이르게 되는 문제점이 있었다.However, as the engine is pushed into the interior of the vehicle crash, the passenger's body is caught between the engine and the seat, which causes delayed transportation to the hospital and even death. There was this.
본 발명은 상기한 제반 문제점을 감안하여 안출된 것으로써, 그 목적은 차량의 정면 충돌사고시 시트가 후방으로 후진됨과 아울러 회전되어 엔진의 밀림 현상에 따른 탑승객의 안전을 도모하기 위한 차량용 시트의 안전장치를 제공하는 데 있다.The present invention has been made in view of the above-described problems, the object of which is that the seat back is reversed in the event of a frontal collision of the vehicle and the rotation is rotated to secure the safety of the vehicle seat for the passengers in accordance with the engine sliding phenomenon To provide.
도 1은 본 발명에 따른 차량용 시트의 안전장치의 구성 및 작동상태를 간략하게 나타낸 도면이다.1 is a view briefly showing the configuration and operation of the safety device for a vehicle seat according to the present invention.

이와 같이 구성된 본 발명 차량용 시트의 안전장치는 다음과 같은 작용을 갖는다.The safety device of the vehicle seat of the present invention configured as described above has the following actions.
차량의 정면 충돌사고시, 충격감지수단(100)에서 이를 감지하여 배터리의 전류를 점화플러그(210)로 통전시키면, 이 점화플러그(210)로부터 스파크가 일어나 기폭제(230)를 기폭시킨다.In the case of a frontal collision of the vehicle, when the shock detection means 100 detects this and energizes the current of the battery with the spark plug 210, sparks are generated from the spark plug 210 to detonate the initiator 230.
이어서, 상기 피스톤부재(240)는 상기 기폭제(230)의 기폭력에 의해 실린더(220)의 내부로 슬라이딩되면서 차량의 전방으로 전진되고, 이 피스톤부재(240)의 전진에 따라 제 1기어부(242)와 치합된 제 2기어부(300)가 도면에 예시된 방향으로 회전하게 된다.Subsequently, the piston member 240 is advanced toward the front of the vehicle while sliding into the cylinder 220 by the detonating force of the initiator 230, and according to the advance of the piston member 240, the first gear portion ( The second gear part 300 meshed with 242 rotates in the direction illustrated in the drawing.
그리고, 상기 제 2기어부(300)의 회전에 따라 제 1,2로드부재(410,430)에 회전력이 전달되어 상기 제 3기어부(420)와 회전롤러(440)가 각각 동작된다.Then, the rotational force is transmitted to the first and second rod members 410 and 430 according to the rotation of the second gear unit 300 to operate the third gear unit 420 and the rotating roller 440, respectively.
이때, 상기 제 3기어부(420)는 제 2기어부(300)의 회전에 따라 회전되는 제 2로드부재(430)에 의해서 동일 방향으로 회전되고, 이 회전에 따라 상기 시트쿠션(500)의 제 4기어부(510)가 후방으로 이동되어 시트가 후진된다.At this time, the third gear portion 420 is rotated in the same direction by the second rod member 430 rotated in accordance with the rotation of the second gear portion 300, according to the rotation of the seat cushion 500 The fourth gear part 510 is moved backward so that the seat is reversed.
또 이와 동시에, 상기 제 2기어부(300)의 회전에 따라 제 1로드부재(410)가 시계바늘방향으로 회전되어 시트쿠션(500)이 후방으로 젖혀진다.At the same time, the first rod member 410 is rotated in the clockwise direction as the second gear part 300 rotates, and the seat cushion 500 is flipped backward.
따라서, 차량의 정면충돌시 엔진이 실내로 들어오더라도 앞좌석 승객의 안전을 도모할 수 있게 된다.Therefore, even when the engine enters the room during a frontal collision of the vehicle, it is possible to secure the safety of the front seat passenger.
이상과 같이 설명한 본 발명 차량용 시트의 안전장치는 차량의 충돌사고시 시트가 회전 및 후진되도록 된 구조를 갖는 것인바, 이에 따르면 충돌사고시 엔진의 밀림현상에 대응하여 탑승객의 몸체가 후진 및 회전되어 탑승객의 안전을 도모할 수 있는 유용한 효과를 갖는다.The safety device of the vehicle seat according to the present invention described above has a structure in which the seat is rotated and retracted during a crash of the vehicle, and accordingly, the body of the passenger is reversed and rotated in response to the jungle phenomenon of the engine during the crash. It has a useful effect to promote safety.
