VEHICLE SEAT DEVICE

摘要

This vehicle seat device is provided with a lock mechanism which restricts sliding movement of the seat, a drive source which has an output unit, a release detection unit which detects the release of restriction by the lock mechanism, and a restriction detection unit which detects restriction by the lock mechanism. In an unpowered state, the drive source exerts a self-restraining force which prevents the output unit from moving. In order to allow the lock mechanism to restrict sliding movement of the seat and to release said restriction on the basis of operation of an operation switch, the drive source drives the output unit in two directions, a positive direction to release restriction and a reverse direction to restrict, in accordance with the direction of current. When releasing restriction on the basis of operation of the operation switch, current is passed through the drive source so that the output unit moves in the positive direction until the release detection unit has detected release, and when the release has been detected, power to the drive source is halted. When restricting on the basis of operation of the operation switch, current is passed through the drive source so that the output unit moves in the reverse direction until the restriction detection unit has detected restriction, and when restriction has been detected, power to the drive source is halted.
