REVENDICATIONS 1. Essuie-glace pour véhicules automobiles, comprenant un bras oscillant autour d'un axe et portant un balai muni d'une lame d'essuyage, caractérisé en ce qu'une extrémité dudit balai comporte une zone cylindrique (5) tourillonnant dans un crochet (6) ménagé sur la face inférieure du bras (1), ledit balai (2) comportant une dent (7) venant s'encliqueter sur une dent (8) du bras (1) au cours de la rotation du balai (2).1. Wiper for motor vehicles, comprising an arm oscillating around an axis and carrying a blade provided with a wiper blade, characterized in that one end of said blade comprises a cylindrical zone (5) journaling in a hook (6) formed on the underside of the arm (1), said broom (2) comprising a tooth (7) which snaps onto a tooth (8) of the arm (1) during the rotation of the broom (2 ). 2. Essuie-glace selon la revendication 1, caractérisé en ce que le balai (2) est constitué d'un support (3) d'une seule pièce portant la lame d'essuyage (4) et le bras (1) comporte un doigt élastique axial (9) en appui sur la face supérieure dudit support (3) après enclique-tage du balai (2) sur le bras (1).2. Windscreen wiper according to claim 1, characterized in that the blade (2) consists of a one-piece support (3) carrying the wiper blade (4) and the arm (1) comprises a axial elastic finger (9) resting on the upper face of said support (3) after snap-floor of the brush (2) on the arm (1). 3. Essuie-glace selon l'une des revendications 1 ou 2, caractérisé en ce que le bras (1) est d'une seule pièce en matière thermoplastique et déformable élastiquement en direction transversale.3. Windscreen wiper according to one of Claims 1 or 2, characterized in that the arm (1) is in one piece made of thermoplastic material and elastically deformable in the transverse direction. La présente invention se rapporte aux essuie-glace pour véhicules automobiles.The present invention relates to wipers for motor vehicles. Les essuie-glace connus comprennent un bras fixé à un axe oscillant entraîné par un moteur électrique, par l'intermédiaire d'une trin-glerie. L'extrémité du bras opposée à l'axe oscillant porte un balai d'essuie-glace constitué par un support déformable qui porte une raclette en caoutchouc. Le balai est monté pivotant à l'extrémité du bras, autour d'un axe orthogonal au balai et qui doit être en dehors du corps du bras pour permettre au balai de pivoter sans interférer avec le bras.Known wipers include an arm attached to an oscillating shaft driven by an electric motor, via a trin-glerie. The end of the arm opposite the oscillating axis carries a wiper blade consisting of a deformable support which carries a rubber blade. The broom is pivotally mounted at the end of the arm, around an axis orthogonal to the broom and which must be outside the body of the arm to allow the broom to pivot without interfering with the arm. Lorsque l'axe de pivotement est, comme dans la plupart des cas, situé au-dessous du corps du bras, l'ensemble de l'essuie-glace est fortement en relief au-dessus de la surface à essuyer, ce qui est nuisible tant sur le plan esthétique que sur le plan aérodynamique. C'est pourquoi on a également proposé de disposer l'axe latéralement par rapport au bras, ce qui introduit le nouvel inconvénient de diminuer la visibilité pour le conducteur.When the pivot pin is, as in most cases, located below the body of the arm, the wiper assembly is highly raised above the surface to be wiped, which is detrimental both aesthetically and aerodynamically. This is why it has also been proposed to arrange the axis laterally with respect to the arm, which introduces the new drawback of reducing visibility for the driver. On connaît également un essuie-glace (brevet allemand N° 1806719) dans lequel le bras est terminé par des ressorts-lames précontraints qui supportent le balai, lequel est ainsi pratiquement dans le prolongement du bras, ce qui évite les inconvénients précédents. Cependant, la construction du bras et la fixation du balai sont compliqués et onéreux et l'esthétique de l'essuie-glace est très discutable.A windshield wiper is also known (German patent No. 1806719) in which the arm is terminated by prestressed leaf springs which support the blade, which is thus practically in the extension of the arm, which avoids the above drawbacks. However, the construction of the arm and the attachment of the blade are complicated and expensive and the aesthetics of the wiper is very questionable. La présente invention vise à obtenir un essuie-glace dans lequel le balai soit pratiquement dans le prolongement du bras d'essuie-glace, avec une construction simple et économique du balai et du bras. Ce but est atteint, conformément à l'invention, grâce à un essuie-5 glace comprenant un bras oscillant autour d'un axe et portant un balai muni d'une lame d'essuyage, caractérisé en ce qu'une extrémité dudit balai comporte une zone cylindrique tourillonnant dans un crochet ménagé sur la face inférieure du bras, ledit balai comportant une dent venant s'encliqueter sur une dent du bras au cours de la ro-io tation du balai.The present invention aims to obtain a windscreen wiper in which the blade is practically an extension of the windscreen wiper arm, with a simple and economical construction of the blade and the arm. This object is achieved, in accordance with the invention, thanks to a windscreen wiper comprising an arm oscillating around an axis and carrying a blade provided with a wiper blade, characterized in that one end of the said blade comprises a cylindrical area rotating in a hook provided on the underside of the arm, said brush having a tooth which snaps onto a tooth of the arm during the ro-io tation of the brush. Le montage du balai par rotation et encliquetage d'une de ses extrémités permet de supprimer les inconvénients précédents avec une forme et un montage extrêmement simples.Mounting the broom by rotating and snapping one of its ends eliminates the above drawbacks with an extremely simple shape and assembly. Avantageusement, le balai est constitué d'un support d'une seule is pièce portant la lame d'essuyage, et le bras comporte un doigt élastique axial en appui sur la face supérieure dudit support après encliquetage du balai sur le bras.Advantageously, the wiper consists of a one-piece support carrying the wiper blade, and the arm includes an axial elastic finger resting on the upper face of said support after the wiper has been snapped onto the arm. De préférence, le bras est d'une seule pièce en matière thermoplastique et déformable élastiquement en direction transvesale. 20 On a représenté aux dessins annexés, à titre d'exemple, un tel essuie-glace.Preferably, the arm is made of a single piece of thermoplastic material and elastically deformable in the transverse direction. 20 There is shown in the accompanying drawings, by way of example, such a wiper. Dans ces dessins:In these drawings: — la fig. 1 est une vue en élévation latérale de l'essuie-glace;— fig. 1 is a side elevational view of the windshield wiper; — la fig. 2 est une vue en élévation latérale d'une partie de l'essuie-25 glace de la fig. 1 en cours de montage;— fig. 2 is a side elevational view of part of the wiper of FIG. 1 under construction; — la fig. 3 est une vue de dessus de l'essuie-glace de la fig. 1 ;— fig. 3 is a top view of the wiper of FIG. 1; — la fig. 4 est identique à la fig. 1, pour une variante;— fig. 4 is identical to FIG. 1, for a variant; — la fig. 5 est une vue de dessus de l'essuie-glace de la fig.— fig. 5 is a top view of the wiper of FIG. 4. L'essuie-glace est constitué d'un bras 1 sur lequel est monté un4. The wiper consists of an arm 1 on which is mounted a 30 balai 2. Le balai est constitué par un support mobile 3 en matière thermoplastique déformable élastiquement et qui peut avoir une précambrure, et une lame d'essuyage 4 portée par le support 3. Une extrémité du support 3 porte deux tétons latéraux 5 qui tourillonnent dans une fourche 6 formée sur la face inférieure du bras 1. Au cours 35 de la rotation du balai 2, une dent 7 formée sur le support 3 vient s'encliqueter sur une dent 8 que porte le bras 1, de sorte que le balai 2 est rendu solidaire du bras 1 dans le prolongement de celui-ci. Au-delà de sa dent 8, le bras 1 est prolongé par un doigt longitudinal élastique 9 qui est cambré vers le balai 2 de manière à lui transmettre 40 une poussée F vers la surface à essuyer.30 broom 2. The broom is constituted by a movable support 3 of elastically deformable thermoplastic material and which may have a pre-curvature, and a wiper blade 4 carried by the support 3. One end of the support 3 carries two lateral studs 5 which pivot in a fork 6 formed on the underside of the arm 1. During the rotation of the broom 2, a tooth 7 formed on the support 3 snaps onto a tooth 8 carried by the arm 1, so that the broom 2 is secured to the arm 1 in the extension thereof. Beyond its tooth 8, the arm 1 is extended by an elastic longitudinal finger 9 which is arched towards the broom 2 so as to transmit to it 40 a thrust F towards the surface to be wiped. Dans la forme d'exécution des fig. 1 à 3, le bras 1 est monobloc en matière thermoplastique et est déformable élastiquement en direction transversale, de manière à appliquer le balai 2 sur la surface à essuyer. Dans la variante des fig. 4 et 5, le bras 1 est, de manière classique, 45 articulé sur une pièce 10 montée oscillante, la pression d'appui étant fournie par un ressort 11.In the embodiment of FIGS. 1 to 3, the arm 1 is a single piece of thermoplastic material and is elastically deformable in the transverse direction, so as to apply the brush 2 to the surface to be wiped. In the variant of FIGS. 4 and 5, the arm 1 is, in a conventional manner, articulated on an oscillating mounted part 10, the support pressure being provided by a spring 11.
