본 발명은 차량의 안티 서브마린 시스템에 관한 것으로서 특히, 차량의 충돌시 발생하는 피칭각에 따라 시트쿠션 전방 내부에 마련된 패널의 승강을 제어하여 차량의 충돌시 서브마린 현상을 방지하기 위한 장치로써, 탑승객의 안전성을 향상시킬 수 있는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-submarine system of a vehicle, and in particular, a device for preventing the submarine phenomenon during a collision of a vehicle by controlling the elevation of a panel provided inside the seat cushion in accordance with a pitching angle generated when the vehicle collides. The present invention relates to a device capable of improving safety.

일반적으로 서브마린(sub-marine) 현상이란, 차량의 전방충돌 혹은 급정거 시에 시트가 내려앉으면서 승객이 인스트루먼트 패널 밑으로 밀려들어가 상해를 입는 현상을 말한다.In general, a sub-marine phenomenon refers to a phenomenon in which a passenger is pushed under an instrument panel while injuring a seat while the vehicle is crashed or stopped suddenly.
