Claim Text:
1. A vehicle seat comprising: a reclining mechanism that is provided to make an angle of a seat back relative to a seat cushion adjustable; a biasing member that biases the seat back in such a direction as to decrease the angle of the seat back relative to the seat cushion; an assist member that applies a force in a direction opposite to a biasing force of the biasing member to the seat back, and generates a force that is smaller than a total of a weight of the seat back and the biasing force of the biasing member when the seat back is lifted up from a forwardly folded position in which the seat back has a small angle relative to the seat cushion toward a sitting position; a hinge portion of the seat back that is provided with the reclining mechanism and the biasing member; another hinge portion of the seat back that is arranged in line with the hinge portion and provided with the assist member; and an assist force cancelling mechanism that limits a range in which the assist member applies the assist force to the seat back so that the assist force is applied only until the seat back is lifted up by a prescribed angle from the forwardly folded position toward the sitting position.
