Description
Bras #orte-balai pour essuie-alace de véhicule automobile.# Broom arm for motor vehicle wiper.
L'invention concerne un bras porte-balai' pour essuie-glace de véhicule- automobile du type constitué d'un corps creux ouvert.The invention relates to a brush-holder arm 'for a wiper of a motor vehicle of the type consisting of an open hollow body.
Les essuie-glace pour Véhicules automobiles sont formés d'un bras porte-balai monté oscillant à une extrémité et dont l'autre extrémité porte un balai d'essuyage monté pivotant autour d'un axe orthogonal au bras.Windshield wipers for motor vehicles are formed by a brush-holder arm mounted oscillating at one end and the other end of which carries a wiper blade pivotally mounted about an axis orthogonal to the arm.
Les bras porte-balai connus sont en général constitués d'un corps à section transversale en forme de U, de préférence la section est symétrique et, pour leur donner- la rigidité nécessaire, leurs - faces latérales ont une hauteur relativement importante. Cette hauteur des faces latérales, qui spnt en général orthogonales à la surface à essuyer, est inesthétique et, surtout, produit une résistance relativement élevée vis-à-vis de l'air et, à grande vitesse et/ou en présence de vents rapides, tend à produire un soulèvement de l'ensemble de ltessuie-glace, ce qui est nuisible à la qualité de l'essuyage.The known brush-holder arms generally consist of a body with a U-shaped cross section, preferably the section is symmetrical and, to give them the necessary rigidity, their side faces have a relatively large height. This height of the lateral faces, which spnt in general orthogonal to the surface to be wiped, is unsightly and, above all, produces a relatively high resistance to air and, at high speed and / or in the presence of fast winds , tends to produce an uplift of the wiper assembly, which is detrimental to the quality of the wiping.
La présente invention vise à diminuer la résistance aérodynamique d'un bras porte-balai du type décrit à l'introduction sans diminuer, et même en augmentant, sa rigidité et sa résistance mécanique.The present invention aims to reduce the aerodynamic resistance of a brush holder arm of the type described in the introduction without reducing, and even increasing, its rigidity and its mechanical strength.
A cet effet, le bras porte-balai selon l'invention est caractérisé en ce qu'il comprend, sur une partie au moins de sa longueur, au moins deux bandes formant un angle non droit entre elles.To this end, the brush-carrying arm according to the invention is characterized in that it comprises, over at least part of its length, at least two bands forming a non-right angle between them.
Lorsqutun tel- bras est monté sur un véhicule automobile, l'une des bandes est sensiblement orthogonale à la surface à essuyer alors que l'autre des bandes est inclinée et forme un angle non droit avec ladite surface à essuyer. When such an arm is mounted on a motor vehicle, one of the bands is substantially orthogonal to the surface to be wiped while the other of the bands is inclined and forms a non-right angle with said surface to be wiped.
On obtient ainsi un bras porte-balai présentant une surface inclinée qui forme une surface déflectrice afin de renforcer la pression du bras, et donc de l'ensemble de ltessuie-glace, contre la surface à essuyer, de plus, à rigidité égale ou superieure, un tel bras a une hauteur réduite par rapport à un bras traditionnel.A wiper arm is thus obtained having an inclined surface which forms a deflecting surface in order to reinforce the pressure of the arm, and therefore of the wiper assembly, against the surface to be wiped, moreover, with equal or greater rigidity. , such an arm has a reduced height compared to a traditional arm.
De préférence, le bras comporte des ajourages disposés sur au moins une partie de sa longueur afin de faciliter l'échappement de l'air sous pression contenu à l'intérieur du bras.Preferably, the arm has openings arranged over at least part of its length in order to facilitate the escape of the pressurized air contained inside the arm.
Dans une forme de réalisation de l'invention, les ajourages sont disposés sur la face présentant la bande inclinée du bras. Ils peuvent aussi, ou en outre, être disposés sur l'autre face du bras porte-balai.In one embodiment of the invention, the openings are arranged on the face having the inclined strip of the arm. They can also, or in addition, be arranged on the other face of the brush holder arm.
Selon une variante, les ajourages sont disposés à cheval sur les faces du bras porte-balai.Alternatively, the openings are arranged astride the faces of the brush holder arm.
Afin d'améliorer le guidage du balai d'essuyage par rapport au bras, qui n'est assuré dans les essuie-glace connus que par l'articulation entre le balai et le bras, l'invention prévoit que l'une au moins des faces du bras porte-balai comporte une bande plane coopérant avec une surface plane correspondante du balai d'essuyage et/ou d'un dispositif de connexion entre le bras et le balai; ladite bande plane pouvant constituer la face dans son ensemble, ce qui sera par exemple le cas pour la face dudit bras destinée à être orthogonale à la surface à essuyer. In order to improve the guidance of the wiper blade relative to the arm, which is only ensured in known windscreen wipers by the articulation between the blade and the arm, the invention provides that at least one of the faces of the brush holder arm comprises a flat strip cooperating with a corresponding flat surface of the wiper blade and / or of a connection device between the arm and the brush; said flat strip can constitute the face as a whole, which will for example be the case for the face of said arm intended to be orthogonal to the surface to be wiped.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel: - la figure 1 est une vue schématîque en coupe transversale d'un bras porte-balai selon ~ un premier exemple de réalisation de l'invention, et - la figure 2 est analogue à la figure li pour une variante.The invention will be better understood on reading the following description made with reference to the accompanying drawing in which: - Figure 1 is a schematic cross-sectional view of a brush holder arm according to ~ a first embodiment of the invention, and - Figure 2 is similar to Figure li for a variant.
Le bras porte-balai 1 est forme d'un corps creux ouvert, selon l'invention, au moins une partie de deux de ses faces, ici les bandes 2 et 3, forment un angle non droit entre elles. Ces bandes sont prévues pour que, lorsque le bras est monté sur le véhicule, la bande 3 soit sensiblement orthogonal#e à la surface à essuyer 5 alors que la bande 2 est inclinée et forme un angle- obtu d avec ladite surface. En positionnant la bande 2 de manière telle qu'elle affronte les filets d'air lors de la descente du balai vers la position d'arrêt fixe, ladite bande sert de déflecteur lors de l'essuyage.The brush-carrying arm 1 is in the form of an open hollow body, according to the invention, at least part of two of its faces, here the bands 2 and 3, form a non-right angle between them. These bands are provided so that, when the arm is mounted on the vehicle, the band 3 is substantially orthogonal # e to the surface to be wiped 5 while the band 2 is inclined and forms an obtuse angle d with said surface. By positioning the strip 2 so that it faces the air streams when the brush is lowered to the fixed stop position, said strip serves as a deflector during wiping.
On appelera ici face avant la face comportant la bande 2 servant de déflecteur et, face arrière, la face comportant la bande 3 destinée à être orthogonale à la surface à essuyer.The face comprising the strip 2 serving as a deflector and the rear face the face comprising the strip 3 intended to be orthogonal to the surface to be wiped will here be called the front face.
La bande 3 forme dans les e#xemples représentés la totalité de la face arrière.The strip 3 forms in the e # xamples shown the whole of the rear face.
Dans l'exemple de la figure 1, la bande inclinée 2 constitue, dans la section considérée, l'ensemble de la face avant du bras 1 alors que, dans la variante de la figure 2, la bande inclinée 2 est prolongée par une bande inférieure 4 sensiblement parallèle a la face arrière 3. In the example of FIG. 1, the inclined strip 2 constitutes, in the section considered, the whole of the front face of the arm 1 whereas, in the variant of FIG. 2, the inclined strip 2 is extended by a strip lower 4 substantially parallel to the rear face 3.
Par contre, lorsque l'on considère la face avant dans sa longueur; la bande 2 peut n'en former qu'une partie.On the other hand, when we consider the front face in its length; strip 2 can only form part thereof.
On obtient dans tôus les cas une rigidité importante du bras avec une hauteur inférieure et une résistance aérodynamique diminuée par rapport a un bras porte-balai traditionnel.In all cases, a high rigidity of the arm is obtained with a lower height and a reduced aerodynamic resistance compared to a traditional brush-carrying arm.
Pour diminuer la résistance aérodynamique du bras en permettant l'échappement de l'air sous pression qu'il contient, l'invention prévoit de munir le bras 1 d'ajourages 5 disposés au moins sur une partie de sa longueur.To reduce the aerodynamic resistance of the arm by allowing the pressurized air it contains to escape, the invention provides the arm 1 with openings 5 arranged at least over part of its length.
Les ajourages 5 peuvent être disposés à cheval sur la bande inclinée 2 et sur la face arrière 3 (figure 1); Ils peuvent aussi être disposés sur la bande inclinée 2 et/ou sur la face arrière 3 du bras porte-balai 1. The openings 5 can be arranged astride the inclined strip 2 and on the rear face 3 (FIG. 1); They can also be arranged on the inclined strip 2 and / or on the rear face 3 of the brush holder arm 1.
La face arrière 3 et, le cas échéant, la bande inférieure 4 de la face avant peuvent être courbes. De préférence, elles sont planes de manière à coopérer avec une surface plane correspondante du balai d'essuyage ou d'un dispositif de connexion entre le bras et le balai (non représentés). La surface de guidage du bras 1 peut être la surface externe et/ou la surface interne de la face arrière 3 et/ou, le cas échéant, la surface externe et/ou la surface interne de la bande 4. The rear face 3 and, where appropriate, the lower strip 4 of the front face can be curved. Preferably, they are planar so as to cooperate with a corresponding flat surface of the wiper blade or of a connection device between the arm and the blade (not shown). The guide surface of the arm 1 can be the external surface and / or the internal surface of the rear face 3 and / or, if necessary, the external surface and / or the internal surface of the strip 4.
