Patent ID: 8038198

Claim:
A vehicle seat comprising: a seat back; a seat cushion; a support base supporting the seat back on a vehicle floor; a front link coupling the support base and the seat cushion to each other and pivotally coupled to each of the support base and the seat cushion; and a rear link coupling the seat cushion and the support base to each other and pivotally coupled to each of the seat cushion and the support base; wherein the seat back is coupled to the support base, so that the seat back can tilt forwardly relative to the support base; wherein the rear link is coupled to the seat cushion at a position rearward of a coupling point of the front link to the seat cushion; and wherein when the seat back is tilted forwardly, the front link and the rear link pivot to cause a downward movement of the seat cushion; and a force transmission device comprising a transmitting section provided at the seat back and a force receiving section provided at the rear link and configured to receive transmission of force from the transmitting section when the seat back is tilted forwardly; wherein as the force is transmitted from the transmitting section to the force receiving section, the rear link pivots together with the front link, so that the seat cushion shifts downward; wherein a point where the force is transmitted from the transmitting section to the force receiving section is set at a higher level than a point where the rear link and the support base are coupled to each other; wherein the rear link pivots relative to the support base in a direction opposite to the tilting direction of the seat back by the force transmitted from the transmitting section when the seat back is tilted forwardly; and wherein the front link pivots relative to the support base in the same direction as the tilting direction of the seat back by receiving the pivoting movement of the rear link.
