Abstract

The subject of the present invention is a windscreen wiper including a drive arm (2) which is connected to a drive shaft (3) capable of giving it an alternating pivoting movement and the arm is itself connected to a waffle tree (balance arm) (5a-5b) carrying a wiper blade (11) equipped with a stiffener (9a-9b). According to the invention, the waffle tree (5a-5b) and the stiffener (9a-9b) can fold so that the shape of the waffle tree and of the wiper blade (11) can, when stopped, resemble as closely as possible the shape of the lower edge (1a) of the windscreen (1).

Description

Les essuie-glace de véhicule automobile comportent un bras d'entrainement qui est relié à un arbre moteur propre à lui imprimer un mouvement de pivotement alternatif et est lui-même relié à un palonnier portant une lame racleuse munie d'un raidisseur.Motor vehicle windshield wipers comprise a drive arm which is connected to a motor shaft capable of imparting to it an alternating pivoting movement and is itself connected to a lifting beam carrying a scraper blade provided with a stiffener.

Lorsque l'essuie-glace est à l'arrêt, il est bon que la lame racleuse en fin de course ne soit pas dans le champ de vision du conducteur. De plus, les lames racleuses de grande taille se trouvent suivant une corde par rapport à l'arête inférieure courbe du parebrise, ce qui est inesthétique. Pour éviter ces inconvénients, il est connu de donner une course supplémentaire au bras d'entraînement en position d'arrêt de l'essuie-glace de façon à dégager entièrement le pare-brise. Mais cette disposition est coûteuse et risque d'entraîner rapidement une dégradation du joint prévu à l'arête inférieure du pare-brise.When the wiper is stopped, it is good that the scraper blade at the end of the race is not in the driver's field of vision. In addition, the large scraper blades are located along a cord relative to the curved lower edge of the windshield, which is unsightly. To avoid these drawbacks, it is known to give an additional stroke to the drive arm in the stop position of the wiper so as to completely release the windshield. However, this arrangement is costly and risks rapidly degrading the seal provided at the lower edge of the windshield.

La présente invention a pour objet un essuie-glace qui pallie ces divers inconvénients
Cet essuie-glace est caractérisé en ce que le palonnier et le raidisseur peuvent se plier de façon que la forme du palonnier et de la lame racleuse puisse, à l'arrêt, se rapprocher le plus possible de celle de l'arête inférieure du pare-brise.The present invention relates to a wiper which overcomes these various drawbacks
This wiper is characterized in that the lifter and the stiffener can bend so that the shape of the lifter and the scraper blade can be as close as possible to that of the lower edge of the visor when stationary. -broken.

inférieure la est courbe et qui est généralement bombé. Ce pare-brise est associé à un essuie-glace comportant un bras d'entraînement 2 qui est fixé sur l'arbre de sortie 3 d'un moteur propre à lui imprimer un mouvement de pivotement alternatif.the lower is curved and which is generally curved. This windshield is associated with a wiper comprising a drive arm 2 which is fixed on the output shaft 3 of a motor capable of imparting to it an alternating pivoting movement.

Au bras 2 est accroché en 4 un palonnier qui est formé de deux demi-éléments Sa et 5b sensiblement de même longueur et reliés par une charnière 6 d'axe A-A sensiblement perpendiculaire au bras 2. Un ressort 7 -tend à maintenir les deux éléments Sa et 5b dans le prolongement l'un de l'autre, le mouvement d'ouverture étant limité par une butée 8 de fin de course.On the arm 2 is hung at 4 a lifter which is formed of two half-elements Sa and 5b substantially of the same length and connected by a hinge 6 of axis AA substantially perpendicular to the arm 2. A spring 7 tends to hold the two elements Sa and 5b in the extension of one another, the opening movement being limited by an end stop 8.

Chacun des demi-éléments Sa et 5b du palonnier porte un élément de raidissement 9a ou 9b; les deux éléments 9a et 9b sont reliés l'un à l'autre par une charnière 10 d'axe A-A et portent une même lame racleuse 11 en élastomère.Each of the half-elements Sa and 5b of the lifter carries a stiffening element 9a or 9b; the two elements 9a and 9b are connected to each other by a hinge 10 of axis A-A and carry the same scraper blade 11 made of elastomer.

L'ensemble formé par le palonnier, les éléments de raidissement et la lame racleuse peut ainsi se plier autour de l'axe A-A. Lors de l'utilisation de 11 essuie-glace le ressort 7 maintient droit cet ensemble, donc la lame racleuse, ce qui est nécessaire au bon fonctionnement de l'essuie-glace. Lors de son arrêt, qui se produit automatiquement en fin de course, l'extrémité de l'élément de raidissement extérieur 9a vient en appui sur l'encadrement du parebrise 1, de sorte que l1essuie-glace se plie et est ainsi rangé de façon esthétique (Figure 1). On peut éventuellement prévoir sur le pare-brise une butée 12 pour cet élément 9a.The assembly formed by the lifting beam, the stiffening elements and the scraper blade can thus bend around the axis A-A. When using 11 wipers, the spring 7 keeps this assembly straight, therefore the scraper blade, which is necessary for the proper functioning of the wiper. When it stops, which occurs automatically at the end of its travel, the end of the external stiffening element 9a comes to bear on the frame of the windshield 1, so that the wiper folds and is thus stored so aesthetic (Figure 1). Optionally, a stop 12 can be provided on the windscreen for this element 9a.

Dans la variante des Figures 3 et 4 la charnière 10 a été supprimée et les deux éléments de raidissement 9a et 9b ne sont liés l'un à l'autre que par la lame racleuse 11 et les éléments du palonnier. In the variant of FIGS. 3 and 4, the hinge 10 has been omitted and the two stiffening elements 9a and 9b are linked to each other only by the scraper blade 11 and the lifting beam elements.

Il va de soi que la présente invention ne doit pas être limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. C'est ainsi, par exemple, que le palonnier et le raidisseur de la lame racleuse pourraient comporter deux axes de pliage écartés l'un de l'autre ou que l'axe de pliage A-A, au lieu d'être médian, pourrait se trouver au voisinage de l'extrémité extérieure de la lame racleuse. Dans l'un ou l'autre cas les axes de pliage seront disposés à proximité du point de liaison P1,P2,P3 P1,P2,P3 ou P4 de deux éléments adjacents du palonnier. It goes without saying that the present invention should not be limited to the embodiment described and shown, but on the contrary covers all variants thereof. Thus, for example, the lifter and the stiffener of the scraper blade could have two folding axes spaced from each other or that the folding axis AA, instead of being median, could find near the outer end of the scraper blade. In either case, the folding axes will be arranged near the connection point P1, P2, P3 P1, P2, P3 or P4 of two adjacent components of the lifter.
