Abstract
A seat position automatic adjusting device used for an automotive vehicle motor-powered front seat comprises a single reversible motor for actuating the adjusting mechanism to adjust each seat member to a desired position. A control circuit counts and stores the number of rotations of the reversible motor and outputs a control signal by calculating the difference between the current seat position data from the stored value and the original seat position data. A drive circuit drives the reversible motor to automatically return the current seat position to the original seat position to the original seat position in response to the control signal from said control circuit.
