Motor-driven adjustable seat, particularly a motor vehicle seat
First Claim
1. In a power driven adjustable seat, particularly a motor vehicle seat having a position adjuster including a servomotor with a driving shaft, a potentiometer coupled to the driving shaft via reduction gears, and an electronic data processing and storing device electrically connected between the potentiometer and the servomotor to store and process the measured value delivered by the potentiometer and to control the position of the seat via the servomotor, a combination comprisinga housing common both to said potentiometer and said reduction gears, the said reduction gears having an input member coupled to said driving shaft and also having an output member;
- andsaid potentiometer having a rotary slider coupled to said output member.

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.
