본 고안은 자동차의 시트쿠션에 설치하여 차량의 전방출돌시 승객의 하체가 앞쪽으로 밀려나가지 못하도록 하는 자동차의 서브마리닝(SUBMARINING) 방지장치에 관한 것이다.The present invention relates to an apparatus for preventing submarining of a vehicle, which is installed on a seat cushion of the vehicle and prevents the lower body of the passenger from being pushed forward when the vehicle moves forward.

종래에는 제1도에 도시한 바와 같이, 차량의 전방출돌시 승객의 하체가 앞쪽으로 밀려나가지 못하도록 하기 위하여 자동차 시트(1)의 시트쿠션(2)에 내장되는 구션 프레임(3) 앞쪽에 서브마리닝 방지 프레임(4)을 결합시켰다.Conventionally, as shown in FIG. 1, the front of the cushion frame 3, which is embedded in the seat cushion 2 of the vehicle seat 1, in order to prevent the lower body of the passenger from being pushed forward when the vehicle moves forward The anti-marining frame 4 was joined.

이 서브마리닝 방지 프레임(4)은 상면이 경사지게 형성되어 있으며, 선단으로 갈수록 상향으로 돌출되어 있다. 그리하여 자동차의 주행중 전방출돌되면 자동차 시트(1)에 탑승한 승객이 하체가 그 충격력으로 인해 전방으로 쏠리게 될 때 쿠션 프레임(3)에 부착된 서브마리닝 방지 프레임(4)이 저지하여 주므로써 승객의 하체의 이동을 저지하는 역할을 하게 된다.The submarining prevention frame 4 is inclined in the upper surface, and protrudes upward toward the tip. Thus, when the vehicle is driven forward while driving, the submarining prevention frame (4) attached to the cushion frame (3) prevents the passengers in the car seat (1) from being lowered forward due to the impact force. It is to prevent the movement of the lower body of the passenger.

이와 같이 종래에는 차량의 전방출돌시 쿠션 프레임(3)에 결합된 서브마리닝 방지 프레임(4)에 의하여 승객이 전방으로 밀려나가는 것을 저지하나 승차감 저해를 초래하기 때문에 서브마리닝 방지 프레임(4) 상면의 경사도에 승객의 하체가 자동차 시트(1) 앞으로 밀려나가는 것을 충분히 저지하지 못하는 단점이 있었다.As described above, the conventional submarining prevention frame 4 prevents the passenger from being pushed forward by the submarining prevention frame 4 coupled to the cushion frame 3 when the vehicle moves forward. ) There was a disadvantage that the lower body of the passenger to the slope of the upper surface does not sufficiently prevent the front of the car seat (1).

본 고안은 종래의 단점을 해소하기 위한 것으로, 차량이 전방충돌하게 되면 시트쿠션에 내설된 쿠션 프레임의 선단부가 상향으로 회동하게 함으로써, 승객의 하체가 시트쿠션상에서 전방으로 밀려나가는 것을 충분히 저지하여 제약을 받는다.The present invention is to solve the disadvantages of the prior art, when the vehicle is crashed forward by the front end of the cushion frame inherent in the seat cushion by rotating upward, the passenger's lower body is sufficiently restrained to be pushed forward on the seat cushion is restricted Receives.

다시 말해서, 서브마리닝 방지 프레임(4) 상면의 경사도를 크게 하면 서브마리닝 방지효과가 향상되나 시트쿠션(2)의 쿠션상태가 불량하게 되고, 서브마리닝 방지 프레임(4) 상면의 경사도를 작게하면 시트쿠션(2)의 쿠션상태가 양호해지나 서브마리닝 방지효과가 불량하게 되는 문제가 있다.In other words, increasing the inclination of the upper surface of the sub-marlining prevention frame 4 improves the sub-marlining prevention effect, but the cushioning state of the seat cushion 2 is poor, and the inclination of the upper surface of the sub-marining prevention frame 4 is improved. When it is made small, there is a problem that the cushion state of the seat cushion 2 becomes good, but the effect of preventing submarining is poor.

따라서 종래에 서브마리닝 방지 프레임(4)이 시트쿠션(2)에 내설된 자동차 시트(1)는 차량충돌시 승객의 피해를 줄이고자 하는데 그 목적이 있다.Therefore, the conventional car seat 1 in which the submarining prevention frame 4 is built in the seat cushion 2 is intended to reduce the damage of passengers when the vehicle crashes.

이와 같은 본 고안의 목적은 전방충돌시 충격량을 감지하여 작동신호를 발생하도록 차량의 전방에 설치된 충돌센서, 상기 충돌센서에서 작동신호가 발생되면 피스톤 로드가 상향으로 연장되므로 시트쿠션의 하부에 설치된 팽창기, 그리고 상기 피스톤 로드가 연장됨에 따라 상향으로 회동되는 상기 시트쿠션에 내설된 쿠션 프레임의 선단에 마련된 회동부로 구성하므로써 달성된다.The purpose of the present invention as described above is an impact sensor installed in the front of the vehicle to detect the impact amount in the front collision, when the operation signal is generated from the collision sensor, the piston rod is extended upwards inflator installed in the lower portion of the seat cushion And a rotating part provided at the tip of the cushion frame embedded in the seat cushion which is rotated upward as the piston rod extends.

이하, 본 고안의 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

제2도에 도시한 바와 같이, 충돌센서(10)가 차량의 전방에 설치되어 있으며, 차량충돌시 일정충격량 이상이 되면 작동신호를 발생하도록 되어 있다.As shown in FIG. 2, the collision sensor 10 is installed in front of the vehicle, and generates an operation signal when the amount of impact is greater than or equal to a certain amount of impact during a vehicle crash.

팽창기(20)는 시트쿠션(2) 하부에 피스톤 로드(21)가 상향으로 설치되어 있어 충돌센서(10)에서 충돌신호가 입력되면 피스톤 로드(21)가 상향으로 연장된다.The expander 20 has a piston rod 21 installed upward in the lower portion of the seat cushion 2, so that when the collision signal is input from the collision sensor 10, the piston rod 21 extends upward.

그리고 회동부(30)는 쿠션 프레임(3)의 선단부가 힌지(31)로 연결되어 있고, 피스톤 로드(21)의 선단이 회동부(30)에 연결되어 있어 팽창기(20)의 피스톤 로드(21)의 연장길이를 크게 하면 회동부(30)의 경사각도를 크게 할 수 있게 된다And the rotating part 30 is the front end of the cushion frame 3 is connected to the hinge 31, the front end of the piston rod 21 is connected to the rotating part 30, the piston rod 21 of the expander 20 Increasing the extension length of the can increase the inclination angle of the rotating part (30).

그리하여 차량이 주행중에 전방충돌되었을 때 충격량이 일정한도 이상이면 차량전방에 설치된 충돌센서(10)에서 작동신호를 발생시키게 됨에 따라 팽창기(20)의 피스톤 로드(21)가 상향으로 연장된다. 동시에 회동부(30)가 상향으로 회동되므로 승객의 하체가 시트쿠션(2) 앞쪽으로 밀려나가게 되는 것을 저지하게 된다.Thus, when the impact amount is more than a certain level when the vehicle is crashed forward while driving, the piston rod 21 of the inflator 20 extends upward as the operation signal is generated by the collision sensor 10 installed in the front of the vehicle. At the same time, since the pivoting part 30 is pivoted upward, the lower body of the passenger is prevented from being pushed forward of the seat cushion 2.

이때 회동부(30)는 종래에 비해 크게 회동되어 경사각이 크게 되므로 승객의 하체가 밀려나가는 것을 충분히 저지할 수 있다.At this time, the rotation unit 30 is rotated larger than in the prior art so that the inclination angle is large, it is possible to sufficiently prevent the lower body of the passenger to be pushed out.

이와 같이 본 고안은 차량충돌시 쿠션 프레임의 선단을, 상향으로 경사각도를 크게하여 회동시킨 것으로, 승객의 하체가 전방으로 밀리는 것을 충분히 저지하게 되어 승객보호 효과가 증대된다. 뿐만 아니라 주행시에는 쿠션 프레임의 선단이 수평한 상태로 되므로써 서트쿠션의 쿠션상태가 양호하여 자동차 시트의 안락감을 향상시킬 수 있게 된다.In this way, the present invention is to rotate the front end of the cushion frame to increase the inclination angle at the time of vehicle collision, it is to sufficiently prevent the lower body of the passenger to be pushed forward to increase the passenger protection effect. In addition, since the front end of the cushion frame is in a horizontal state while driving, the cushion of the cushion cushion is good, thereby improving the comfort of the car seat.
