ABSTRACT:
The present invention provides a vehicle seat capable of performing a tilt-down operation in which a seat back is widely tilted forwardly to be folded on a seat cushion while a seat cushion is moved forwardly and a walk-in operation in which the seat back is half tilted forwardly over a desired angle while the seat is slid forwardly via a slide rail. The seat includes a frame member that is capable of longitudinally sliding via the slide rail and that supports the seat back via a reclining device so as to tilt the seat back back and forth, a front link connecting the seat cushion to the frame member so as to allow the seat cushion to move longitudinally, and an interlock mechanism that can be controlled so as to move or to not move the seat cushion forwardly with respect to the frame member when the seat back is tilted forwardly. At the time of the tilt-down operation, the interlock mechanism is controlled so as to move the seat cushion forwardly when the seat back is tilted forwardly. At the time of the walk-in operation, the interlock mechanism is controlled so as to not move the seat cushion forwardly when the seat back is tilted forwardly.
