Claim:
A vehicle seat comprising: a seat back that is placed in one of a first position and a second position relative to a mounting portion of a vehicle body on which the seat back is mounted; a seat cushion that is placed in one of a first position and a second position relative to a mounting portion of the vehicle body on which the seat cushion is mounted; and a linked position-changing unit that moves the seat back and the seat cushion in relation to each other, so as to change the seat back and the seat cushion between the first positions and the second positions, wherein the linked position-changing unit includes a multi-point pivot link coupling the seat back with the seat cushion and a straight link pivotally coupled to a front end of the seat cushion such that when the seat back and the seat cushion are moved between the first positions and the second positions, respectively, the straight link and the multi-point pivot link move in relation to one another, when the seat back is in the first position, the seat back is inclined forward in a frontward direction of the vehicle seat relative to the seat back when the seat back is in the second position, and when the seat back is in the second position, the seat back is reclined backwards in a rearward direction of the vehicle seat relative to the seat back when the seat back is in the first position, and the linked position-changing unit moves the seat back and the seat cushion in relation to each other, so that a back contact point of the seat back, at which a predetermined portion of a back of a seated person contacts the seat back when the seat back and the seat cushion are in the first positions, is located at substantially the same position as a predetermined portion of the back of the seated person when the seat back and the seat cushion are in the second positions and so that an ischial contact point of the seat cushion, at which a tuber of ischium of the seated person contacts the seat cushion when the seat back and the seat cushion are in the first positions, is located at substantially the same position as the tuber of ischium of the seated person when the seat back and the seat cushion are in the second positions.
