Abstract

The potentiometer and reduction gear unit for use in connection with a seat adjuster driven by a servomotor and controlled by a microprocessor which recallably stores the value measured by the potentiometer, comprises a common housing assembled of two parts arranged about the driving shaft of the motor; one housing part accommodates the reduction gears and the other part supports a ringshaped resistor and a contact ring; the slider of the potentiometer bridges the contact ring and resistor ring and is frictionally coupled to the output member of the reduction gears, formed preferably as a wobble gear mechanism.
