Abstract: A height adjusting device for an automotive seat which is actuated by rotation of a drive rod through a gear and link mechanism. The seating height adjustment is locked and unlocked by means of a stopper and lock gear mechanism. A lock releasing means is provided in the stopper and lock gear mechanism such that raising and lowering of an operation lever causes the disengagement of the stopper from the lock gear though the lock releasing means to permit a desired higher or lower seating height adjustment, without any other special operations. The lock releasing means comprises a wire member and release plate.
