Abstract

L'invention concerne une serrure de porte pour véhicule automobile, comportant un moyen de verrouillage (3) qui est raccordé à un moteur électrique à courant continu (7) pour fournir une assistance à la fermeture, et des moyens de raccordement (8, 9, 12) servant à convertir le mouvement de rotation du moteur à courant continu (7) en un mouvement de verrouillage. Le moteur à courant continu (7) déplace les moyens de raccordement d'une position initiale à une position de fermeture. Des moyens mécaniques de rappel exercent une force de rappel sur les moyens de raccordement dans la direction de la position initiale. En cas de suppression de l'alimentation en tension du moteur à courant continu (7), les moyens de rappel ramènent les moyens de raccordement dans la position initiale, le retour des moyens de raccordement étant converti en un mouvement du moteur à courant continu (7) générant une tension. Un circuit électrique servant à activer le moteur à courant continu présente un premier chemin muni de composants discrets parallèles au moteur à courant continu (7), le premier chemin présentant au moins une diode de protection (26) et au moins un composant discret monté en série par rapport à la diode sous la forme d'une résistance ohmique (27) ou d'une diode Zener (28).
