Abstract
Description
La présente invention concerne une raclette d'essuyage pour un balai d'essuie-glace de véhicule automobile. The present invention relates to a wiper blade for a wiper blade of a motor vehicle.
L'invention concerne plus particulièrement une raclette d'essuyage du type comportant une lame d'essuyage en matériau déformable élastiquement qui coopère avec la vitre à essuyer et qui comporte une tête supérieure de liaison prévue pour être reliée à une structure de support articulée du balai d'essuie-glace. The invention relates more particularly to a wiper of the type comprising a wiper blade of elastically deformable material which cooperates with the window to be wiped and which comprises an upper connecting head intended to be connected to an articulated support structure of the brush. wiper.
Afin de permettre d'effectuer un nettoyage de la vitre, même en l'absence d'intempéries, il est nécessaire d'équiper les dispositifs d'essuie-glace de moyens d'alimentation et d'aspersion en liquide de lavage pour asperger la vitre à nettoyer. In order to allow cleaning of the window, even in the absence of bad weather, it is necessary to equip the wiper devices with means of supply and spraying of washing liquid to spray the glass to clean.
Il est souhaitable que les moyens d'aspersion du liquide soient agencés le plus près possible de la lame d'essuyage et à proximité de la vitre à essuyer. It is desirable that the means for spraying the liquid are arranged as close as possible to the wiping blade and close to the window to be wiped.
Dans ce but, il a déjà été proposé dans le document DE-A-2.106.555 de réaliser une raclette d'essuyage qui incorpore la rampe d'aspersion en liquide de lavage. Ce document propose divers modes de réalisation dans lesquels la rampe est constituée pour l'essentiel par un ou plusieurs canaux d'alimentation formés dans le corps de la tête de liaison ou dans le corps de la lame d'essuyage et par une série d'orifices d'aspersion qui sont orientés en direction de la vitre à essuyer de part et d'autre de la lame d'essuyage. To this end, it has already been proposed in document DE-A-2,106,555 to produce a wiping squeegee which incorporates the spray liquid spray bar. This document proposes various embodiments in which the ramp consists essentially of one or more supply channels formed in the body of the connection head or in the body of the wiping blade and by a series of spray holes which are oriented towards the glass to be wiped on either side of the wiping blade.
On constate toutefois que, dans une telle conception, les jets d'aspersion de liquide de lavage sont situés dans une zone qui est soumise à des turbulences aérodynamiques particulièrement importantes qui nuisent d'une part au fonctionnement efficace de la lame d'essuyage proprement dite ainsi qu'à la qualité d'aspersion de la vitre par le liquide de lavage. However, it can be seen that, in such a design, the washing liquid spray jets are located in an area which is subjected to particularly significant aerodynamic turbulence which on the one hand impairs the effective functioning of the wiper blade itself as well as the quality of spraying of the glass by the washing liquid.
Afin de remédier à ces inconvénients, la présente invention propose une raclette d'essuyage du type mentionné précédemment, caractérisée en ce que ladite lame comporte en outre au moins un déflecteur qui s'étend longitudinalement vis-à-vis d'une des faces latérales de la lame d'essuyage et à proximité de la vitre à essuyer, et en ce que la rampe d'aspersion en liquide de lavage est associée au déflecteur. In order to remedy these drawbacks, the present invention provides a wiping squeegee of the type mentioned above, characterized in that said blade further comprises at least one deflector which extends longitudinally with respect to one of the lateral faces of the wiping blade and near the window to be wiped, and in that the spraying liquid spray boom is associated with the deflector.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre pour la compréhension de laquelle on se reportera au dessin annexé dont la figure unique est une vue en section transversale par un plan perpendiculaire au plan longitudinal médian commun à la raclette et à la lame d'essuyage. Other characteristics and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawing, the single figure of which is a view in cross section through a plane perpendicular to the median longitudinal plane. common to the squeegee and the wiping blade.
On a représenté sur la figure une raclette d'essuyage 10 pour un balai d'essuie-glace (non représenté) d'un essuie-glace qui permet l'essuyage et le nettoyage d'une vitre 12. There is shown in the figure a wiper blade 10 for a wiper blade (not shown) of a wiper which allows the wiping and cleaning of a window 12.
Selon une conception connue, la raclette d'essuyage 10 comporte une lame d'essuyage ou de raclage proprement dite 14 et une tête supérieure de liaison 16 qui est prévue pour être reliée à la structure de support articulée du balai d'essuie-glace. According to a known design, the wiper blade 10 comprises a wiping or scraping blade proper 14 and an upper connecting head 16 which is intended to be connected to the articulated support structure of the wiper blade.
A cet effet, la tête 16 comporte un talon supérieur de rigidification 18 qui s'étend longitudinalement, c'est-à-dire selon une direction perpendiculaire au plan de la figure et qui est relié à une âme 20 de la lame. To this end, the head 16 has an upper stiffening heel 18 which extends longitudinally, that is to say in a direction perpendicular to the plane of the figure and which is connected to a core 20 of the blade.
La structure articulée comporte une succession de griffes 22, dont l'une est illustrée en section transversale sur la figure, à l'intérieur desquelles est reçu le talon 18 de la tête 16 de la lame d'essuyage 14. The articulated structure comprises a succession of claws 22, one of which is illustrated in cross section in the figure, inside which is received the heel 18 of the head 16 of the wiping blade 14.
Selon une conception connue, la lame d'essuyage 14 est reliée à l'âme 20 par une bande longitudinale de liaison 24 et par une ailette de protection 26. According to a known design, the wiping blade 14 is connected to the core 20 by a longitudinal connecting strip 24 and by a protective fin 26.
L'ailette 26 s'étend longitudinalement dans un plan perpendiculaire au plan longitudinal médian P qui est le plan de symétrie de conception de la lame 14 et de la raclette 10. The fin 26 extends longitudinally in a plane perpendicular to the median longitudinal plane P which is the plane of symmetry of design of the blade 14 and the squeegee 10.
L'ailette 26 comporte ainsi deux branches 28 qui s'étendent latéralement de part et d'autre du plan médian
P.The fin 26 thus comprises two branches 28 which extend laterally on either side of the median plane
P.
Selon une technique connue, la lame 14, la bande 24, l'ailette 28 et l'âme 20 sont réalisées par extrusion d'un matériau déformable élastiquement. According to a known technique, the blade 14, the strip 24, the fin 28 and the core 20 are produced by extruding an elastically deformable material.
Conformément à l'invention, la raclette 10 comporte au moins un déflecteur 30 qui s'étend longitudinalement en vis-à-vis d'une des faces latérales opposées 32 de la lame d'essuyage 14 et dont le bord inférieur 34 est situé à proximité de la vitre à essuyer. According to the invention, the squeegee 10 comprises at least one deflector 30 which extends longitudinally opposite one of the opposite lateral faces 32 of the wiping blade 14 and whose lower edge 34 is located at near the glass to be wiped.
Dans le mode de réalisation illustré sur la figure, le déflecteur 30 présente la forme d'une ailette profilée réalisée par extrusion et venue de matière avec la lame 14. A cet effet, le bord longitudinal supérieur 36 du déflecteur 30 est relié au bord latéral 38 de l'ailette 28 correspondante. In the embodiment illustrated in the figure, the deflector 30 has the shape of a profiled fin produced by extrusion and formed integrally with the blade 14. For this purpose, the upper longitudinal edge 36 of the deflector 30 is connected to the lateral edge 38 of the corresponding fin 28.
Le corps 40 du déflecteur 30 comporte, à sa partie inférieure à proximité du bord longitudinal inférieur 34, un canal 42 d'alimentation en liquide de lavage qui est formé dans la masse du corps 40. The body 40 of the deflector 30 comprises, at its lower part near the lower longitudinal edge 34, a channel 42 for supplying washing liquid which is formed in the mass of the body 40.
Le canal 42 communique avec une source d'alimentation en liquide de lavage (non représentée) et avec une série d'orifices d'aspersion 44, ou avec une fente longitudinale d'aspersion, qui sont orientés en direction de la vitre à essuyer 12 et inclinés de manière à être également orientés légèrement en direction de la face latérale en vis-à-vis 32 de la lame d'essuyage 14. The channel 42 communicates with a source of washing liquid supply (not shown) and with a series of spray holes 44, or with a longitudinal spray slot, which are oriented towards the window to be wiped 12 and inclined so as to also be oriented slightly towards the lateral face opposite 32 of the wiping blade 14.
Les orifices d'aspersion 44 permettent donc d'asperger la portion 13 de la face supérieure de la vitre à essuyer 12 qui s'étend en regard de l'espace 46 délimité latéralement par la face latérale 32 de la lame d'essuyage 14 et par la face latérale en vis-à-vis 48 du corps 40 du déflecteur 30. The spray orifices 44 therefore make it possible to spray the portion 13 of the upper face of the wiping glass 12 which extends opposite the space 46 delimited laterally by the lateral face 32 of the wiping blade 14 and by the lateral face opposite 48 of the body 40 of the deflector 30.
Grâce à la conception selon l'invention, la lame d'essuyage 14 est protégée contre les effets néfastes du vent aérodynamique relatif V et les jets d'aspersion provenant des orifices 44 sont dans l'espace 46 qui est également protégé des effets du vent aérodynamique V. Thanks to the design according to the invention, the wiper blade 14 is protected against the harmful effects of the relative aerodynamic wind V and the spray jets coming from the orifices 44 are in the space 46 which is also protected from the effects of the wind aerodynamics V.
Selon une autre caractéristique de l'invention, le talon de rigidification 18 peut être réalisé simultanément avec la lame d'essuyage 14 par un procédé de co-extrusion. According to another characteristic of the invention, the stiffening heel 18 can be produced simultaneously with the wiping blade 14 by a co-extrusion process.
Selon une variante non représentée, il est bien entendu possible de conférer à la raclette 10 une symétrie de conception par rapport au plan longitudinal médian P en prévoyant que la lame d'essuyage 14 comporte deux déflecteurs agencés symétriquement de part et d'autre, chacun des déflecteurs pouvant comporter une rampe de distribution de liquide de lavage. According to a variant not shown, it is of course possible to give the squeegee 10 a symmetry of design with respect to the median longitudinal plane P by providing that the wiping blade 14 comprises two deflectors arranged symmetrically on either side, each deflectors which may include a ramp for dispensing washing liquid.
