Abstract

La présente invention concerne un balai d'essuie-glace qui comprend un support de caoutchouc. Une paire de sections de retenue est disposée sur les deux extrémités dans la direction longitudinale du support de caoutchouc et un caoutchouc d'essuie-glace est retenu par le support de caoutchouc sur la paire de sections de retenue. Une paire d'éléments de revêtement (17) en matériau à base de résine est disposée sur les deux côtés dans la direction longitudinale du support de caoutchouc. Des branches de raccordement (41) formées intégralement avec les éléments de revêtement (17) en matériau à base de résine sont disposées sur les éléments de revêtement (17). Les éléments de revêtement (17) sont raccordés de manière rotative au support de caoutchouc sur les branches de raccordement (41). Un élément de renfort métallique (43) est emboîté dans une branche de raccordement (41) et dans un élément de revêtement (17) par moulage d'insert, et l'élément de renfort (43) augmente la rigidité de la branche de raccord (41) par rapport à l'élément de revêtement (17).
