Abstract: A seat for a vehicle includes a seat cushion, a seat back, and a reclining device configured to allow the seat back to be tilted to the seat cushion. The seat back includes a back frame having an opening and a pipe frame comprising a pipe member, and the pipe frame includes a distal end part. The lower part of the pipe frame extends through the opening such that the distal end part is located inside a space defined by the back frame and the reclining device, and the lower part of the pipe frame is fixed to the back frame at the opening. Rotation center of the reclining device is set so as to be aligned with axial center of the lower part of the pipe frame.

Abstract: In a rear seat having a configuration which, in the state that a seat cushion is folded forward with a seat back flattened on the seat cushion side, makes an upward back surface of the seat back become almost the same height with a floor surface of a cargo room, to avoid giving a restriction and hurt in amenity to a passenger seated on the seat cushion in the space on which feet of are put, the present invention provides a vehicle seat to which parallel link mechanism portions are equipped that connect the seat cushion to a floor surface under the seat cushion of the vehicle, and a mechanism is provided to fold the seat cushion forward with the posture of the seat back held by the parallel link mechanisms in the state that the seat back is flattened to the seat cushion side.
