Abstract

Observing that the section of elastic material (rubber for example), the active part of a windscreen wiper, breaks along its length and that the origin of the break is situated at the ends of the section, it is appropriate to decrease the pulling-out loads on its end parts by increasing the length of that portion of the section which receives this load, which is done by folding over the corner of each end of the lip of the section, as represented on the appended drawing, refs. 1 and 2 (the clamp ref. 4 and the metal stiffener ref. 3 undergoing no modification), and also, in order to prevent breakages in line with the fasteners by which the strip is fastened to the clip, by making a cutout in the wing of the section as represented (section aa and bb) in the appended drawing.

Description

DESCRIPTION
Cette invention concerne une modification des balais d'essuieglaces des véhicules à moteur qu'ils soient à balayage semicirculaire ou rectiligne afin d'en augmenter la durée d'utilisation.DESCRIPTION
This invention relates to a modification of wiper blades of motor vehicles whether they are semi-circular or rectilinear sweep in order to increase the duration of use.

Observant que le profilé de matière élastique (caoutchouc par exemple), partie active de l'essuie-glace, se rompt dans sa longueur et que l'origine de la rupture se situe aux extrémités du profilé, il convient de diminuer l'effort d'arrachement en ses parties extrèmes, en augmentant la longueur de la portion du profilé recevant cette effort, ce qui se réalise par l'abattement d'un angle de 45 +/-5 par exemple de chaque extrémité de la lèvre Rep. 2 du profilé (1) tel que représenté sur le dessin ci-joint en figure 1 et 2. L'étrier (4) et le raidisseur (2) des figures 1 et 2 ne subissant pas de modification.Observing that the profile of elastic material (rubber for example), active part of the wiper, breaks in its length and that the origin of the rupture is located at the ends of the profile, the effort d 'tearing in its extreme parts, increasing the length of the portion of the profile receiving this force, which is achieved by the reduction of an angle of 45 +/- 5 for example of each end of the lip Rep. 2 of the profile (1) as shown in the attached drawing in Figure 1 and 2. The stirrup (4) and the stiffener (2) of Figures 1 and 2 not undergoing modification.

Une amorce de rupture se situe également aux points d t attaches de l'étrier et du profilé. Cette attache s'insère entre deux ailes de ce profilé et, de ce fait, supprime, à cet endroit, la souplesse de ltâme du profilé et apporte à la lèvre un surcroit d'effort qui provoque sa rupture. A fracture initiator is also located at the points of attachment of the stirrup and of the profile. This fastener is inserted between two wings of this profile and, therefore, removes, at this location, the flexibility of the soul of the profile and brings to the lip an additional effort which causes its rupture.

Pour pallier cet inconvénient, une découpe (C) d'une aile du profilé à chaque point d'attache, selon figures 1, 2 et 3 du dessin ci-joint, de part et d'autre de l'amie dudit profilé, découpe d'une longueur égale à la largeur de 1 t attache, plus un jeu de fonctionnement, permettent à l'âme de retrouver une souplesse sur toute sa longueur. To overcome this drawback, a cut (C) of a wing of the profile at each attachment point, according to Figures 1, 2 and 3 of the attached drawing, on either side of the friend of said profile, cut with a length equal to the width of 1 t fastener, plus an operating clearance, allow the core to regain flexibility over its entire length.

REVENDICATION CLAIM La présente invention s'applique à tous les balais d'essuieglaces de véhicules à moteur, qu'ils soient à balayage semicirculaire ou rectiligne, afin d'en augmenter la durée d'utilisation, caractérisée par l'abattement de l'angle de chaque extrémité de la lèvre (2) du profilé élastique (1), de 450 +/-5 et, pour prévenir les ruptures aux droits des attaches du profilé (1) sur l'étrier (4) en pratiquant une découpe (C) de l'aile du profilé, découpe d'une longueur égale à la largeur de l'attache plus un jeu de fonctionnement. The present invention applies to all wiper blades of motor vehicles, whether they are semi-circular or rectilinear, in order to increase the duration of use, characterized by the reduction in the angle of each end of the lip (2) of the elastic profile (1), of 450 +/- 5 and, to prevent ruptures at the rights of the fasteners of the profile (1) on the stirrup (4) by making a cutout (C) of the profile wing, cut to a length equal to the width of the fastener plus a working clearance.
