Abstract

The device comprises for each window an electric driving motor and a selector which is adapted to ensure the selective supply of current to the motor, in one direction or the other, through a control circuit acting on a supply source. The supply source is of the type capable of delivering at least two distinct energy levels. The control circuit comprises means for applying to an input of the supply source an energy level control signal which produces, as a function of the position of the selector, the application of a torque to the motor when raising the window which is higher than the torque applied when descending the window.
