A setting in position identification potentiometer is connected to terminals of the motor. The motor is supplied with a voltage (U.sub.feed) possibly variable and switchable between two reverse polarity states according to rotation direction. The potentiometer has a slider which is connected via a first dividing bridge to input of an analog-digital converter subjected to a reference voltage (U.sub.ref) connected to same possibly variable voltage via a second dividing bridge. Output of the analog-digital converter is connected to an electronic module. The resistor value at the ground of each of the two dividing bridges is respectively equal to a product of the other resistor value by a same multiplying coefficient A.

Simplified supplying system of the position identification

A centralized control unit that includes supply circuits for supplying various motors for controlling movements of parts of a vehicle seat, an in-board power source for feeding the supply circuits, an inverting device for enabling a control with inversion in a rotation direction of the various motors, and a study carrying wheel having a set of studs for enabling a selection of each of the various motors, with each of the set of studs being connected to a circuit of one of the various motors for controlling one of the parts of the seat.
