ABSTRACT:
A seat assembly for automatically adjusting a seat position of a seat mounted, for example, in a vehicle, includes an actuator, an electric source, a controller, a non-operation maintainer, a stop lamp switch and a cancellation switch. The actuator adjusts the seat, and the electric source supplies electricity to the actuator.
The controller controls the actuator and outputs a controlling signal to the actuator.
The non-operation maintainer maintains a non-operation condition of the actuator and the non-operation maintainer is electrically connected between the actuator and the electric source. The non-operation maintainer selectively supplies the electricity to the actuator.
The stop lamp switch outputs a stop signal to the non-operation maintainer, and the non-operation maintainer starts maintaining the non-operation condition of the controller in accordance with the receipt of the stop signal.
The cancellation switch outputs a cancellation signal to the non-operation maintainer, and the non-operation maintainer cancels the non-operation condition of the actuator in accordance with the receipt of the cancellation signal.
