Abstract
Abstract This system for controlling the operation of reversible motor-speed reducer modules for adjusting in position elements of a motor vehicle seat structure is characterized in that the motor-speed reducer modules (1,2) are connected in parallel to common supply means (3), whose output voltage direction is piloted by a control module (4), and to this control module (4) through a multiplexed network (5) for the transmission of data piloting said motor-speed reducer module to permit the actuation or non-actuation, in one direction of rotation or the other, of each motor-speed reducer module (1,2) for adjusting in position each element of the seat structure.
