Title
(EN) LIQUID SPRAYING WIPER FRAME FOR MOTOR VEHICLE WINDOWS, AND OPTIMISATION OF THE SEALING OF THIS FRAME
(FR) BALAI D'ESSUIE-GLACE À PROJECTION DE LIQUIDE POUR VITRE DE VÉHICULE AUTOMOBILE, ET PERFECTIONNENT DE L 'ÉTANCHÉITÉ DE CE BALAI
Abstract
(EN)
The invention relates to a wiper frame (10) comprising a device (24), in particular an aerodynamic deflector, for dispensing and/or spraying liquid, comprising at least one liquid flow channel (26), a longitudinal end (27) of which opens on an end face (28) of the device (24), a plug (40) for closing off the longitudinal end (27) of the liquid flow channel (26), which is inserted inside a longitudinal end section (27) of said channel (26), and a tip (30) arranged opposite the end face (28) of the device (24), characterised in that the closing plug (40) is a separate component from the tip (30), such as a spherical ball, such that the tip (30) and the plug (40) together ensure the closing off of the longitudinal end (27) of the liquid flow channel (26).
(FR)
L'invention propose un balai (10) d'essuie-glace comprenant un dispositif (24), notamment un déflecteur aérodynamique, de distribution et/ou de projection de liquide comportant au moins un canal (26) de circulation de liquide dont une extrémité longitudinale (27) débouche dans une face d'extrémité (28) du dispositif (24), un bouchon (40) d'obturation de l'extrémité longitudinale (27) du canal (26) de circulation de liquide qui est inséré à l'intérieur d'un tronçon d'extrémité longitudinale (27) dudit canal (26), et un embout (30) agencé en vis-à-vis de la face d'extrémité (28) du dispositif (24), caractérisé en ce que le bouchon (40) d'obturation est un composant distinct de l'embout (30), tel qu'une bille sphérique, de manière que l'embout (30) et le bouchon (40) assurent ensemble l'obturation de l'extrémité longitudinale (27) du canal (26) de circulation de liquide.
