The present invention relates to a sinking mechanism for a seat of a vehicle that allows the seat mounted on the vehicle to be received in a reception space recessed on the bottom surface of a vehicle body, and the sinking mechanism includes: upper and lower articulation links pinned to a front lower side of a seat cushion; a connecting link configured to fold or unfold the upper and lower articulation links by moving in a forward/rearward direction by a folding switching link as a seat back is rotated; and a four-bar linkage mechanism connected to the rear end of the connecting link. The four-bar linkage mechanism includes: a recliner in which a fourth link is fixed to the rear upper end of the reception space under the seat, in which a first link, a second link, and a third link pivot in an upward/downward direction with respect to first and second rotation points of the fourth link in conjunction with the forward/rearward movement of the connecting link, and which mediates relative rotations of the first link and the second link; and a manipulation lever configured to allow or interrupt relative rotations of the first link and the second link by rotating a driving shaft of the recliner. The present invention provides a linkage mechanism that is coupled to a lower side of a seat to allow the seat to be received in a reception space recessed on the bottom surface of a vehicle body.

    본 발명은 차량 내 장착되는 시트를 차체 바닥면에 함입 형성되는 수납공간에 수납될 수 있게 해주는 차량용 시트의 싱킹(sinking) 메커니즘에 관한 것으로서, 시트쿠션의 전방 하부에 핀(pin)이음된 상,하부 분절링크와; 시트백의 회전에 따라 절첩 전환 링크에 의해 전후방향으로 운동함으로써 상기 상,하부 분절링크 사이를 접거나 펼치는 커넥팅 링크와; 상기 커넥팅 링크의 후단에 연결되는 4절 링크 메커니즘을 포함하되, 상기 4절 링크 메커니즘은, 제4 링크가 시트 하부의 수납공간 후방 상단부에 고정되고, 상기 커넥팅 링크의 전후방향 운동과 연동하여 상기 제1 링크, 제2 링크 및 제3 링크가 상기 제 4 링크의 제1, 제2 회전점을 기준으로 상하방향으로 선회하는 운동을 하고, 상기 제1 링크와 상기 제2 링크의 상대회전을 매개하는 리클라이너와; 상기 리클라이너의 구동축을 회전조작함으로써 상기 제1 링크와 상기 제2 링크 간의 상대회전을 허용 또는 차단하는 조작레버를 포함하는 것을 특징으로 한다.
