Afin que l'unité de poignée tournante (10) présente, malgré l'utilisation d'un organe de positionnement électrique ou électronique, un comportement que l'utilisateur connaît dans le cas d'une transmission Bowden actionnée par la poignée tournante et d'un organe de positionnement chargé par ressort, il est proposé selon l'invention qu'en plus de l'élément élastique, la poignée tournante soit associée à un élément de friction (80) qui, lors de la rotation de la poignée tournante à partir de la position de départ et en direction de la position de rotation maximale, produit une résistance par friction supérieure à la rotation de la poignée tournante dans la direction opposée.
