Abstract

The blade (14) has a wiper (20) with a vertical section (26) and a horizontal section, encased by the stiffer backing section (28). The backing section carries an aerodynamic portion (38) in softer material, and embodies a wiper fluid channel (44). The blade is gripped by claws (18), holding it to the wiper arm. The reinforcement can be a covering (30) which encloses the coupling blade.

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 un talon supérieur de liaison, destiné à être relié à des griffes appartenant à des composants d'une structure articulée de liaison d'un balai d'essuie-glace, et une lame d'essuyage reliée au talon par une bande longitudinale de liaison, du type réalisée sous la forme d'un profilé extrudé en matériau souple et du type comportant des moyens de renfort du talon de liaison. The invention relates more particularly to a wiper blade of the type comprising an upper connecting heel, intended to be connected to claws belonging to components of an articulated structure for connecting a wiper blade, and a wiper blade connected to the heel by a longitudinal connecting strip, of the type produced in the form of an extruded profile of flexible material and of the type comprising means for reinforcing the connecting heel.

Afin d'assurer un bon entraînement en balayage de la raclette d'essuyage, il est nécessaire de renforcer le talon supérieur de liaison pour lui conférer une rigidité transversale suffisante évitant sa déformation de manière qu'il constitue un socle par rapport auquel la lame d'essuyage peut pivoter, et également afin de permettre l'accrochage des griffes d'extrémités des composants de la structure articulée de liaison qui sont par exemple formées aux extrémités libres des bras d'étriers d'articulation. In order to ensure a good sweeping drive of the wiping squeegee, it is necessary to reinforce the upper connecting heel to give it sufficient transverse rigidity avoiding its deformation so that it constitutes a base relative to which the blade d wiping can pivot, and also in order to allow the attachment of the end claws of the components of the articulated connecting structure which are for example formed at the free ends of the arms of articulation stirrups.

Selon une conception connue, une ou plusieurs vertèbres longitudinales de renfort sont réalisées sous la forme d'éléments séparés en forme de plaques qui sont insérés dans des rainures longitudinales du talon réalisées venues de matière lors de l'extrusion du corps de la raclette. According to a known design, one or more longitudinal reinforcing vertebrae are produced in the form of separate elements in the form of plates which are inserted into longitudinal grooves in the heel produced integrally during the extrusion of the body of the squeegee.

Ces conceptions sont particulièrement complexes dans la mesure où elles nécessitent de réaliser indépendamment des vertèbres de renfort, de préférence en acier inoxydable ou en matière plastique, puis de les assembler au talon rainuré et enfin d'assurer l'immobilisation longitudinale des vertèbres par rapport au talon.  These designs are particularly complex insofar as they require independent reinforcement vertebrae, preferably made of stainless steel or plastic, then to assemble them with the grooved heel and finally to ensure the longitudinal immobilization of the vertebrae relative to the heel.

La présente invention a pour but de remédier à ces inconvénients en faisant appel à la technique dite de biextrusion également appelée extrusion bi-matières. The present invention aims to remedy these drawbacks by using the technique called biextrusion also called bi-material extrusion.

Dans ce but, l'invention propose une raclette d'essuyage du type mentionné précédemment, caractérisée en ce que le talon supérieur est renforcé par un élément longitudinal de renfort réalisé en une seule pièce avec le talon par bi-extrusion en matériau plus rigide que le matériau souple constitutif de la raclette. For this purpose, the invention provides a wiping squeegee of the type mentioned above, characterized in that the upper heel is reinforced by a longitudinal reinforcing element produced in one piece with the heel by bi-extrusion made of a more rigid material than the flexible material constituting the squeegee.

Selon d'autres caractéristiques de l'invention
- l'élément de renfort est une couche de renfort qui enveloppe le talon de liaison
- au moins un accessoire est réalisé par extrusion en une seule pièce avec la raclette
- l'accessoire est un bouclier aérodynamique latéral qui est réalisé par extrusion en matériau souple;
- le bouclier prolonge une aile latérale de l'enveloppe de renfort du talon
- l'accessoire est un conduit longitudinal latéral d'aspersion en liquide de lavage de la vitre à essuyer qui est réalisé par extrusion en matériau plus rigide
- le conduit d'aspersion prolonge une aile latérale de l'enveloppe de renfort du talon.According to other features of the invention
- the reinforcing element is a reinforcing layer which envelops the connecting heel
- at least one accessory is produced by extrusion in one piece with the squeegee
- the accessory is a lateral aerodynamic shield which is produced by extrusion in flexible material;
- the shield extends a lateral wing of the heel reinforcement shell
- the accessory is a longitudinal lateral duct for spraying washing liquid from the window to be wiped, which is produced by extrusion of more rigid material
- the spray duct extends a lateral wing of the heel reinforcement envelope.

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 perspective à grande échelle d'un tronçon d'extrémité d'une raclette d'essuyage réalisée conformément aux enseignements de l'invention en association avec une griffe appartenant à un étrier de liaison. 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 large-scale perspective view of a section of end of a wiper blade produced in accordance with the teachings of the invention in association with a claw belonging to a connecting stirrup.

On a représenté sur la figure 1 une raclette d'essuyage 14 pour un essuie-glace (non représenté) comportant une structure articulée de support de la raclette dont on a représenté une griffe d'extrémité 16 comportant deux branches latérales opposées 18. FIG. 1 shows a wiping squeegee 14 for a wiper (not shown) comprising an articulated structure for supporting the squeegee, an end claw 16 having two opposite lateral branches 18 shown.

La raclette d'essuyage 14 est réalisée en matériau souple et elle est pour l'essentiel constituée par une lame inférieure d'essuyage 20 dont le bord longitudinal inférieur 22 est prévu pour coopérer avec la surface à essuyer, et par un talon massif de liaison 24 auquel elle est reliée par une bande médiane longitudinale de liaison 26. The wiping squeegee 14 is made of flexible material and is essentially constituted by a lower wiping blade 20 whose lower longitudinal edge 22 is provided to cooperate with the surface to be wiped, and by a solid connecting heel 24 to which it is connected by a longitudinal central connecting strip 26.

L'ensemble constitué par la lame 20, la bande 26 et le talon massif 24 est réalisé par extrusion en une seule pièce dans un matériau "souple" au sens de l'invention. The assembly constituted by the blade 20, the band 26 and the solid heel 24 is produced by extrusion in one piece in a "flexible" material within the meaning of the invention.

Comme on peut le voir sur la figure, et afin de conférer une plus grande rigidité au talon supérieur 24, cette partie de la raclette d'essuyage 14 est renforcée par une enveloppe de renfort 28 dont le profil épouse sur une grande partie de sa hauteur celui de la bande médiane de liaison 26 ainsi que celui du talon massif de liaison 24. As can be seen in the figure, and in order to give greater rigidity to the upper heel 24, this part of the wiping squeegee 14 is reinforced by a reinforcing casing 28 whose profile matches over a large part of its height. that of the central connecting strip 26 as well as that of the solid connecting heel 24.

L'enveloppe 28 est une couche d'épaisseur sensiblement constante 30 qui est réalisée simultanément par extrusion avec les parties 20, 26 et 24 de la raclette 14 en un matériau plus rigide, ou moins souple, que celui mentionné précédemment. The casing 28 is a layer of substantially constant thickness 30 which is produced simultaneously by extrusion with the parts 20, 26 and 24 of the squeegee 14 made of a more rigid, or less flexible, material than that mentioned above.

On réalisé ainsi simultanément, grâce à la technique de l'extrusion bi-matières, une raclette d'essuyage comportant un talon longitudinal supérieur 24 renforcé par une enveloppe plus rigide 28. A wiping squeegee is thus produced simultaneously, using the bi-material extrusion technique, comprising an upper longitudinal heel 24 reinforced by a more rigid casing 28.

Dans le mode de réalisation illustré sur la figure 1, la couche 30 constitutive de l'enveloppe en matériau plus rigide 28 épouse la partie supérieure de la bande médiane de liaison 26, puis se prolonge latéralement de part et d'autre de cette bande médiane 26 par deux ailes latérales opposées 32 et 34 qui s'étendent sensiblement dans un même plan et qui délimitent notamment des rainures opposées 36 qui reçoivent les pattes transversales inférieures 37 des branches verticales 18 de la griffe 16. In the embodiment illustrated in FIG. 1, the layer 30 constituting the envelope of more rigid material 28 follows the upper part of the median connecting strip 26, then extends laterally on either side of this median strip 26 by two opposite lateral wings 32 and 34 which extend substantially in the same plane and which in particular delimit opposite grooves 36 which receive the lower transverse lugs 37 of the vertical branches 18 of the claw 16.

Conformément à un autre aspect de l'invention, la raclette 14 est également munie d'un bouclier latéral aérodynamique 38 et d'une rampe latérale d'arrosage 40. In accordance with another aspect of the invention, the squeegee 14 is also provided with an aerodynamic side shield 38 and a side spray bar 40.

Le bouclier longitudinal 38 est réalisé venu de matière par extrusion dans le matériau le plus souple et il s'étend depuis la face inférieure de l'aile latérale 34 en matériau plus rigide, verticalement vers le bas en regard de la partie supérieure de la lame d'essuyage 20 comportant deux ailes de renfort 42 qui limitent également les mouvements de pivotement de la lame 20 de part et d'autre du plan vertical médian de symétrie de l'ensemble. The longitudinal shield 38 is produced integrally by extrusion in the most flexible material and it extends from the underside of the lateral wing 34 of more rigid material, vertically downward facing the upper part of the blade wiping 20 comprising two reinforcing wings 42 which also limit the pivoting movements of the blade 20 on either side of the median vertical plane of symmetry of the assembly.

La rampe d'arrosage 40 est réalisée venue de matière par extrusion dans le matériau le plus rigide et elle est formée au bord d'extrémité libre de l'aile latérale 32 de l'enveloppe de renfort 28. The spray bar 40 is produced integrally by extrusion in the most rigid material and it is formed at the free end edge of the lateral wing 32 of the reinforcing casing 28.

La rampe 40 se présente sous la forme d'un conduit tubulaire creux 44 réalisé par extrusion et elle comporte également des orifices d'aspersion 46 qui sont réalisés ultérieurement, c'est-à-dire après la phase de biextrusion.  The ramp 40 is in the form of a hollow tubular conduit 44 produced by extrusion and it also comprises spray orifices 46 which are produced subsequently, that is to say after the biextrusion phase.
