먼저, 도 1과 도2에 도시한 바와 같이, 본 발명의 프론트 시트에서는 승객이 앉는 부분인 시트 쿠션을 2개의 부분으로 나누어 구성하였다. 즉, 힌지(16)를 중심으로 전방에 배치되는 프론트 쿠션(12)과 후방에 배치되는 리어 쿠션(12')으로 구분하여 형성하였다. 또한, 프론트 쿠션(12)의 하부에는 정면 충돌사고시에 프론트 쿠션(12)을 들어올려 승객을 보호하기 위한 시트 쿠션 높이조절장치가 설치되어 있다.First, as shown in Figs. 1 and 2, the front seat of the present invention is configured by dividing the seat cushion, which is a part where the passenger sits, into two parts. That is, the front cushion 12 disposed in front of the hinge 16 and the rear cushion 12 'disposed in the rear are formed to be divided. In addition, the lower portion of the front cushion 12 is provided with a seat cushion height adjustment device for protecting the passenger by lifting the front cushion 12 in the event of a frontal collision.

이것의 구성을 보면, 시트 트랙(10)에는 고정 전자석(22)을 구비한 하우징(20)을 부착하였으며, 하우징(20)의 내부에는 회동핀(28)을 증심으로 회동 가능하게 장착되는 가동판(24)을 설치하였다. 가동판(24)의 외주부에는 하우징(20)에 부착된 고정 전자석(22)과 대향으로 배치되는 이동 전자석(26)을 부착하였으며, 상단의 내측면에는 걸림턱(24a)을 형성하였다.In view of this configuration, the seat track 10 has a housing 20 having a fixed electromagnet 22 attached thereto, and a movable plate to which the pivot pin 28 can be pivotally mounted in the housing 20. (24) was installed. A movable electromagnet 26 disposed opposite to the fixed electromagnet 22 attached to the housing 20 was attached to the outer circumferential portion of the movable plate 24, and a locking step 24a was formed on the inner side of the upper end.

또한, 가동판(24)의 내부에는 가압 스프링(30)을 삽입한 다음, 가압 스프링(30)의 상부에는 상부 플레이트(32)를 올려 놓았다. 상부 플레이트(32)는 가압부(34)를 개재하여 프론트 쿠션(12)을 상승시키는 역할을 지닌 것으로, 평상시에는 가동판(24)의 걸림턱(24a)에 걸어 맞춤되어 있다. 그리고, 전자제어유닛(36)은 충돌감지센서(38)에서 전달되는 신호에 따라 고정 전자석(22)에 전류를 공급하게 된다.In addition, the pressure spring 30 was inserted into the movable plate 24, and then the upper plate 32 was placed on the pressure spring 30. The upper plate 32 has a role of raising the front cushion 12 through the pressing portion 34, and is normally engaged with the engaging jaw 24a of the movable plate 24. The electronic control unit 36 supplies current to the fixed electromagnet 22 according to a signal transmitted from the collision detection sensor 38.

그에 따라서, 도 3에 도시한 바와 같이, 가동판(24)에 부착된 이동 전자석(26)이 하우징(20)에 부착된 고정 전자석(22)쪽으로 당겨지면서 상부 플레이트(32)와 걸림턱(24a)간의 걸어 맞춤상태가 해제된다. 이와 동시에, 상부 플레이트(32)는 가압 스프링(30)에 의해 상방으로 가압되면서 가압부(34)를 통해 프론트 쿠션(12)을 밀어 올림으로써, 승객의 무릎부분을 보호할 수 있게 된다.Accordingly, as shown in FIG. 3, the mobile electromagnet 26 attached to the movable plate 24 is pulled toward the fixed electromagnet 22 attached to the housing 20 while the upper plate 32 and the locking jaw 24a are attached. ) Is released. At the same time, while the upper plate 32 is pushed upward by the pressing spring 30, by pushing the front cushion 12 through the pressing portion 34, it is possible to protect the knee portion of the passenger.

이상으로 설명한 본 발명에 의하면, 차량의 정면 충돌사고시에 시트 쿠션의 앞부분을 들어올림으로써, 무릎 아래부분에 상처를 입는 것을 막을 수 있는 효과가 있다.According to the present invention described above, by lifting the front portion of the seat cushion during the frontal collision of the vehicle, there is an effect that can prevent the injury to the lower part of the knee.
