The present invention relates to an apparatus for folding and walk-in motions of a vehicle seat. An object of the present invention is to provide an apparatus for folding and walk-in motions of a vehicle seat in which both folding and walk-in motions can be performed with a simple configuration so that the actuating force can be accurately transferred and the maintenance work can be easily performed. According to the present invention, a lever plate, a back frame, a walk-in cam and a walk-in plate, which are integrally connected to a recliner shaft, are sequentially operated according to the operation of a walk-in cable to perform the walk-in motion by the operation of a track cable connected to the walk-in plate. As a folding cable operates, the link plate rotates the walk-in cam in a direction opposite to the rotational direction of the walk-in motion so that the walk-in cam deviates from the rotation radius (R) of the back frame. Then, the lever plate is subsequently rotated such that the folding is performed by the rotation of the back frame.

    본 발명은 차량용 시트의 폴딩 겸용 워크인 장치에 관한 것으로, 그 목적은 간단한 구성에 의해 폴딩 및 워크인 동작이 모두 이루어지도록 하여, 신속하고 정확한 작동력의 전달 및 유지보수가 용이하게 이루어질 수 있는 차량용 시트의 폴딩 겸용 워크인 장치를 제공하는 것이다. 본 발명은 워크인 케이블의 작동에 의해, 리클라이너 샤프트가 일체로 연결된 레버플레이트, 백프레임, 워크인 캠과 워크인 플레이트가 순차적으로 작동되어 워크인 플레이트에 연결된 트랙케이블의 작동에 의해 워크인 작동이 이루어지고, 폴딩 케이블의 작동에 의해, 링크플레이트가, 워크인 작동시의 회전방향과 반대되는 방향으로 워크인 캠을 회전시켜 백프레임의 회전반경(R)으로부터 워크인 캠을 이탈시킨 후, 후속적으로 레버플레이트를 회전시켜 백프레임의 회전에 의해 폴딩이 이루어지도록 구성되어 있다.
