Abstract

L'invention concerne un mécanisme de verrouillage (10) limitant l'ouverture d'une porte avant (1) et comprenant : un limiteur (3) formé à partir d'un élément séparé de la porte avant (1); et un levier de verrouillage (2) fixé de manière rotative à la porte avant (1) et se déplaçant entre une position d'ouverture restreinte, dans laquelle l'ouverture de la porte avant (1) est limitée en venant en contact avec le limiteur (3), et une position d'ouverture autorisée dans laquelle l'ouverture de la porte avant (1) est autorisée en évitant le contact avec le limiteur (3). Le levier de verrouillage (2) comprend une section évidée (22b) en tant que section de restriction de rotation qui limite le déplacement vers la position autorisée d'ouverture dans la zone de contact avec le limiteur (3).
