Abstract

L'invention concerne une serrure de porte de véhicule à moteur équipée d'un mécanisme d'encliquetage (2, 3) sensiblement composé d'un pêne pivotant (2) et d'un cliquet (3). En outre, elle présente un élément de déclenchement (6) pour le mécanisme d'encliquetage (2, 3). Par ailleurs, elle présente également un élément d'accumulation (7) maintenant l'élément de déclenchement (6) et donc le cliquet (3), au moins pendant le mouvement d'ouverture du pêne pivotant (2), dans une position inactive par rapport au mécanisme d'encliquetage (2, 3). Selon l'invention, l'élément d'accumulation (7) est conçu comme un élément de réglage (7) entraîné par un moteur qui libère l'élément de déclenchement (6) en fonction de la position d'ouverture atteinte du pêne pivotant (2).
