Abstract

L'invention concerne un système d'essuie-glace sur un véhicule, les extrémités des arbres d'essuie-glace devant être conçues de façon déformable en cas d'impact avec un corps. Pour réaliser une telle fonction supplémentaire sans devoir toucher à la structure du système d'essuie-glace, on emploie un dispositif de fixation destiné à fixer le système d'essuie-glace au véhicule, permettant d'absorber l'énergie de choc notamment en cas d'impact entre un piéton et le véhicule. Le dispositif de fixation selon l'invention comporte un corps en caoutchouc (13), une douille à palier caoutchouc (15) et une douille de fixation (14). Selon l'invention, le dispositif de fixation comporte une structure de connexion pouvant être séparée en cas de dépassement d'une charge prédéfinie.
