Abstract

L'invention concerne un dispositif essuie-glace. Selon l'invention, un support pivotant de côté AS (17), réalisé sous la forme d'une tige pleine, est muni d'un côté dans le sens longitudinal d'une pièce de fixation de châssis (17b) à laquelle est fixé un élément de châssis (24), et de l'autre côté dans le sens longitudinal d'une pièce de fixation de moteur (17d) à laquelle est fixée une boîte d'engrenage (28a) d'un moteur d'essuie-glace (26). Entre la pièce de fixation de châssis (17b) et la pièce de fixation de moteur (17d) se trouve une pièce support (17c) qui supporte de manière rotative un arbre de pivotement de côté AS (15b) de telle sorte que ledit arbre de pivotement s'étend dans la direction la plus courte du support pivotant de côté AS (17). Le moteur d'essuie-glace (26) peut ainsi être fixé à la pièce de fixation de moteur (17d) sans pattes de fixation et il devient possible de réaliser un dispositif essuie-glace (14) compact, léger et sans pattes de fixation avec des propriétés d'implantation et des propriétés d'assemblage améliorées.
