Abstract

L'invention concerne un assemblage d'essuyeur de pare-brise à lame de faisceau comportant un bras allongé possédant une longueur de faisceau longitudinale orientée entre une première et une seconde extrémités du bras, et une surface supérieure et une surface de montage opposée dotée d'un premier et d'un second côtés entre la surface supérieure et la surface de montage. La distance entre la surface supérieure et la surface de montage sur le bras définit l'épaisseur de ce dernier. De même, la distance entre le premier et le second côtés définit la largeur du bras. Un élément d'essuyeur est monté sur la surface de montage du bras et s'oriente sur la plus grande partie de sa longueur de faisceau longitudinale. Le bras définit un axe des X orienté en direction de la longueur de faisceau longitudinale, un axe des Y orienté transversalement à l'axe des X et par la surface supérieure et la surface de montage, de manière à définir un plan X,Y ainsi qu'un axe Z orienté perpendiculairement au plan X,Y. De plus, la largeur du bras varie entre la première et la seconde extrémités longitudinales. L'épaisseur du bras reste constante entre la première et la seconde extrémités longitudinales. Par ailleurs, le bras varie ou s'incurve à partir de l'axe des X et vers l'axe des Z dans la vue de dessus.
