Abstract:
1. A vehicular seat device comprising: a seat cushion; a seatback which is provided on a base member via a reclining mechanism and whose inclination angle is adjustable; a cooperation portion that changes a posture of the seat cushion synchronously with tilting of the seatback; and a drive mechanism configured to rotationally drive a member of the cooperation portion about a position on the seatback, the drive mechanism including a first force transmission member, a second force transmission member, and an idle gear which is located between the first force transmission member and the second force transmission member and which meshes with the first force transmission member and the second force transmission member, the second force transmission member being coupled coaxially to the member of the cooperation portion and being configured to be rotationally driven; wherein as seat arrangements, the vehicular seat device assumes an entry/exit state in which the seatback is tilted forward and the seat cushion is in a flipped position, a retracted state in which the seat cushion is moved forward downward relative to a vehicle and the seat cushion is superimposed on an upper side of the seatback, and a seating state in which the seatback is not tilted forward, and the seat cushion is not moved forward downward relative to the vehicle or the seat cushion is not in the flipped position, and the seat arrangement is changed via the cooperation portion; and wherein the first transmission member is configured to pivot and the second transmission member and the idle gear are configured to rotate counterclockwise when the seat arrangement is changed between the seating state and the retracted state.
