Abstract

L'invention porte sur un dispositif de montage dans un véhicule, lequel dispositif comporte un boîtier (20) ayant une molette rotative (partie convexe) (30) faisant saillie à partir d'un tableau de bord (11) ; et un élément d'accouplement (50) pour accoupler le boîtier et un support (13) à l'intérieur du tableau de bord, de telle sorte que le boîtier est fixé en une position prédéterminée. L'élément d'accouplement a : une partie de montage côté véhicule (52) destinée à être montée sur le support ; une partie de montage côté boîtier (51) destinée à être montée de façon détachable sur le boîtier ; et une partie d'accouplement (53) pour accoupler la partie de montage côté véhicule à la partie de montage côté boîtier. La partie de montage côté véhicule est reliée à la partie d'accouplement de façon à faire saillie à partir de la surface de la partie d'accouplement. Une partie fragile (531) est formée dans la partie d'accouplement de façon à entourer la jonction avec la partie de montage côté véhicule, et est établie de façon à être endommagée quand une charge d'impact supérieure ou égale à une valeur prédéterminée est appliquée sur la partie convexe à partir d'un côté conducteur, de façon à produire ainsi une perte de fonction d'accouplement. Ceci rend possible d'accroître l'aptitude à la réparation après que la partie convexe a reçu une charge d'impact.
