Abstract

The subject of the present invention is a windscreen wiper including an arm head (1) fixed to a drive shaft and an arm (6) carrying the blade (7) and mounted so that it pivots with respect to the arm head (1) about an axis substantially perpendicular to the axis of pivoting (2) of this head. According to the invention, this windscreen wiper includes means (12) for causing the blade-holder arm (6) to pivot so that the blade (7) constantly remains perpendicular to the surface of the windscreen (10).

Description

En général la raclette de 1 1essuie-glace d'un pare-brise de véhicule automobile se déplace en restant parallèle à elle-même. Or actuellement les pare-brise sont galbés.In general, the squeegee of a windscreen wiper of a motor vehicle windshield moves while remaining parallel to itself. Now, the windshields are curved.

Lorsque le bras portant la raclette se trouve dans sa position médiane la raclette est perpendiculaire au pare-brise; mais lorsque le bras est au voisinage de l'une ou l'autre de ses positions extrêmes, la raclette fait avec le plan tangent au pare-brise, à la ligne de contact, un angle qui est par exemple de 15 . Ceci oblige de réaliser la raclette en une matière présentant une grande souplesse, ce qui est incompatible avec les efforts importants avec lesquels la raclette doit être appliquée sur le pare-brise pour obtenir un nettoyage satisfaisant à grande vitesse.When the arm carrying the squeegee is in its middle position the squeegee is perpendicular to the windshield; but when the arm is in the vicinity of one or the other of its extreme positions, the squeegee makes with the plane tangent to the windshield, to the contact line, an angle which is for example 15. This forces the squeegee to be made of a material having great flexibility, which is incompatible with the significant efforts with which the squeegee must be applied to the windshield in order to obtain satisfactory cleaning at high speed.

De plus, la flexion répétée de la raclette est la principale cause de détérioration de celle-ci.In addition, the repeated bending of the squeegee is the main cause of deterioration thereof.

La présente invention a pour objet un essuie-glace perfectionné de manière à remédier à ces inconvénients.The present invention relates to an improved windscreen wiper so as to remedy these drawbacks.

L'essuie-glace selon l'invention est caràctérisé en ce que le bras porte-raclette est monté pivotant par rapport à la tête de bras autour d'un axe sensiblement perpendiculaire à l'axe de pivotement de ce bras et en ce qu'il comporte des moyens pour faire pivoter le bras porte-raclette de façon que la raclette reste constamment perpendiculaire à la surface du pare-brise.The wiper according to the invention is characterized in that the squeegee arm is pivotally mounted relative to the arm head about an axis substantially perpendicular to the pivot axis of this arm and in that it includes means for pivoting the squeegee arm so that the squeegee remains constantly perpendicular to the surface of the windshield.

Les moyens pour faire pivoter le bras porte-raclette pourraient être un moteur électrique synchronisé avec le moteur électrique d'entraînement du bras.The means for pivoting the squeegee arm could be an electric motor synchronized with the electric motor driving the arm.

Mais dans un mode de réalisation particulier de l'invention, ces moyens comprennent une came fixe sur laquelle peut se déplacer au moins un galet porté par le bras.However, in a particular embodiment of the invention, these means include a fixed cam on which at least one roller carried by the arm can move.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de l'essuie-glace selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en perspective de
l'essuie-glace;
La Figure 2 en est une vue de dessus;
La Figure 3 en est une coupe longitudinale;
La Figure 4 est un schéma montrant le pivotement
de la raclette lors du mouvement de la tête
de bras.
An embodiment of the wiper according to the invention has been described below, by way of non-limiting example, with reference to the accompanying drawings in which
Figure 1 is a perspective view of
the wiper;
Figure 2 is a top view;
Figure 3 is a longitudinal section;
Figure 4 is a diagram showing the pivoting
of the squeegee during the movement of the head
of arms.

Tel qu'il est représenté au dessin, l'essuie-glace selon 11 invention comprend une tête de bras 1 qui est fixée sur un arbre d'entraînement 2. Cette tête est solidaire d'un tourillon la dont l'axe est longitudinal et perpendiculaire à celui de l'arbre 2 et sur lequel est monté pivotant un carter de bras 3. Un ressort 4 monté sur le tourillon la maintient le carter 3 en appui sur la tête 1.As shown in the drawing, the wiper according to the invention comprises an arm head 1 which is fixed to a drive shaft 2. This head is integral with a journal la whose axis is longitudinal and perpendicular to that of the shaft 2 and on which is pivotally mounted an arm casing 3. A spring 4 mounted on the journal keeps the casing 3 in abutment on the head 1.

Le bras 6 de l'essuie-glace qui porte la raclette 7, est monté pivotant sur le carter 3, autour d'un axe 8 perpendiculaire aux axes du tourillon la et de l'arbre 2. Un ressort 9, qui prend appui sur le carter 3, tend à faire pivoter le bras 6 de façon que la raclette 7 soit pressée sur le pare-brise 10.The arm 6 of the wiper which carries the squeegee 7, is pivotally mounted on the casing 3, around an axis 8 perpendicular to the axes of the journal la and of the shaft 2. A spring 9, which rests on the casing 3 tends to pivot the arm 6 so that the squeegee 7 is pressed on the windshield 10.

Le carter 3 porte, de part et d'autre de l'axe du bras 6, deux galets lla et lib coopérant avec une came 12. Cette came est assujettie sur un endroit fixe par rapport au pare-brise 10 par exemple sur le capot, sur la grille d'auvent ou sur le vitrage.The casing 3 carries, on either side of the axis of the arm 6, two rollers lla and lib cooperating with a cam 12. This cam is fixed on a fixed location relative to the windshield 10 for example on the hood , on the awning grille or on the glazing.

Elle a la forme d'une portion de cylindre coaxiale à l'arbre 2. Lorsque la tête de bras 1 pivote les galets lla et llb roulent sur la face active 12a de la came, ce qui produit un pivotement du bras 3 par rapport à la tête de bras 1. Cette face est déterminée en fonction du galbe du pare-brise 10 de façon que la raclette 7 lui reste perpendiculaire, comme le montre la Figure 4.It has the shape of a cylinder portion coaxial with the shaft 2. When the arm head 1 pivots the rollers lla and llb roll on the active face 12a of the cam, which produces a pivoting of the arm 3 relative to the arm head 1. This face is determined as a function of the curve of the windshield 10 so that the squeegee 7 remains perpendicular thereto, as shown in FIG. 4.

L'arbre d'entraînement 2 peut coulisser axialement par rapport à la came 12 et est claveté coulissant sur l'arbre de sortie d'un moteur d'entraînement 13.The drive shaft 2 can slide axially relative to the cam 12 and is keyed sliding on the output shaft of a drive motor 13.

Un ressort 14 interposé entre la came 12 et l'arbre 2 tend à déplacer axialement cet arbre de façon que les galets lla et îlb soient pressés sur la came 12.A spring 14 interposed between the cam 12 and the shaft 2 tends to move this shaft axially so that the rollers 11a and 11b are pressed on the cam 12.

Lors du pivotement de la tête de bras 1 sous l'action du moteur 13, les galets lla et 11b en roulant sur la came 12 font pivoter le carter de bras 3 de sorte que la raclette 7 reste constamment perpendiculaire au pare-brise 10 (Figure 4).During the pivoting of the arm head 1 under the action of the motor 13, the rollers lla and 11b while rolling on the cam 12 rotate the arm casing 3 so that the squeegee 7 remains constantly perpendicular to the windshield 10 ( Figure 4).

Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
