Abstract:
1. A vehicle seat device comprising a lock mechanism, which restricts sliding movement of a seat; a drive source having an output portion that is selectively moveable in a forward direction and a reverse direction, wherein the drive source is configured to, in a non-current supplied state, generate self-constriction force to restrict the output portion from being moved, and, in a current supplied state, selectively drive the output portion in two directions, that is, the forward direction, in which restriction is cancelled, and the reverse direction, in which the restriction is performed, in accordance with a direction in which current is supplied such that sliding movement of the seat is restricted by the lock mechanism and the restriction is cancelled based on operation of an operation switch; a cancellation detection portion, which detects that the restriction by the lock mechanism is cancelled; and a restriction detection portion, which detects that the restriction by the lock mechanism is performed, wherein the vehicle seat device is configured such that when cancelling the restriction based on the operation of the operation switch, the current is supplied to the drive source to drive the output portion in the forward direction until the cancellation is detected by the cancellation detection portion, and when the cancellation is detected, the supply of current to the drive source is stopped, and when performing the restriction based on the operation of the operation switch, the current is supplied to the drive source to move the output portion in the reverse direction until the restriction is detected by the restriction detection portion, and when the restriction is detected, the supply of current to the drive source is stopped.
