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.

Dependent claims

A seat assembly for automatically adjusting a seat position of a mounted seat comprising:

an actuator means for adjusting the seat;
an electric source for supplying electricity to said actuator means;
a controller means for controlling said actuator means, said controller means outputting a controlling signal to said actuator means;
a non-operation maintaining means for maintaining a non-operation condition of said actuator means, said non-operation maintaining means being electrically connected between said actuator means and said electric source, said non-operation maintaining means selectively supplying electricity with said actuator means;
a stop signal generating means for outputting a stop signal to said non-operation maintaining means, said non-operation for maintaining means begins a maintaining of the non-operation condition of said actuator means in accordance with the receipt of the stop signal, whereby once said stop signal generating means outputs the stop signal to said non-operation maintaining means, said non-operation maintaining means maintains the non-operation condition of said actuator means;
and
a cancellation signal generating means for outputting a cancellation signal to said non-operation maintaining means, said non-operation maintaining means cancelling the non-operation condition of said actuator means in accordance with the receipt of the cancellation signal, whereby when said cancellation signal generating means outputs the cancellation signal to said non-operation maintaining means, said non-operation maintaining means cancels the non-operation condition of said actuator means, so that said electric source supplies the electricity to said actuator means and said actuator means adjusts the seat in accordance with the controlling signal of said controller means.
