Abstract

A seat cushion is to pivot to be in a horizontal reversed state and it has a back side. A seat back is to pivot to be in a horizontal reversed state and has a reverse side. The reverse side in the horizontal reversed state has a height substantially equal to one of the back side of the seat cushion in the horizontal reversed state. An arm is attached to a lower end of the seat back and supports the lower end of the seat back to be rotated. A roller is fixed to a lower end of the arm and projects outward in a transverse direction of a vehicle body. A slide rail is fixed to a floor and engages with the roller to be slid forward and rearward. A lock mechanism detachably engages with the roller. A back link is connected to an intermediate fulcrum of the seat back above the roller and is connected to one of an intermediate portion of the slide rail and a peripheral member around the portion. A stopper is provided at the lower end of the seat back. The stopper engages with the arm for preventing the arm from rotating. An operating means is for releasing engagement with the stopper and the arm and is provided at an upper part of the seat back. The seat back pivots forward to be in a horizontal reversed state when releasing the lock mechanism and sliding the roller of the seatback rearward. The seat back pivots on the lower end thereof to fall down rearward for a reclining state when releasing engagement with the stopper and the arm.
