Description

La présente invention concerne un lève-vitre, notamment pour véhicule automobile, du type comportant une glissière, un chariot solidaire de la vitre et susceptible d'être déplacé le long de la glissière au moyen d'un câble passant sur deux poulies de renvoi et s'enroulant sur un tambour d'un treuil de manoeuvre.The present invention relates to a window regulator, in particular for a motor vehicle, of the type comprising a slide, a carriage integral with the window and capable of being moved along the slide by means of a cable passing over two deflection pulleys and winding on a drum of an operating winch.

De tels lève-vitre sont couramment utilisés pour lever et baisser les vitres des portes de véhicules automobiles. Toutefois, comme les portes des véhicules fabriqués actuellement sont convexes, il s'ensuit une courbure des glissières le long desquelles se déplacent les chariots solidaires des vitres.Such window regulators are commonly used to raise and lower the windows of the doors of motor vehicles. However, as the doors of vehicles currently manufactured are convex, it follows a curvature of the slides along which move the carriages integral with the windows.

Dans de tels lève-vitre, la longueur du câble entre les deux poulies de renvoi est égale à la somme des longueurs de câble de chacune des poulies au chariot, c'est à dire à la somme des deux petits côtés du triangle variable dont les sommets sont constitués par les deux poulies et le chariot. La longueur du câble entre les deux poulies de renvoi varie donc lorsque le chariot se déplace d'une extrémité à l'autre de la glissière, ce qui entraine une variation de la tension du câble.In such window regulators, the length of the cable between the two deflection pulleys is equal to the sum of the cable lengths of each of the pulleys to the carriage, that is to say the sum of the two short sides of the variable triangle whose tops are formed by the two pulleys and the carriage. The length of the cable between the two return pulleys therefore varies when the carriage moves from one end to the other of the slide, which causes a variation in the tension of the cable.

Le dispositif décrit dans le brevet français n° 2 193 412, tente de remédier à cet inconvénient en utilisant au moins une poulie élastique et des arrêts de gaines permettant d'assurer, par une précontrainte des gaines enveloppant le câble, une tension convenable du câble de manoeuvre. Toutefois, cette solution entraine des désagréments pour l'utilisateur (jeu avant fonctionnement au niveau de la manivelle de manoeuvre et/ou effort plus important à exercer sur celle-ci à peu près à mi-course) et entraine une usure prématurée du lève-vitre en raison des tensions exercées sur ses divers éléments.The device described in French Patent No. 2,193,412 attempts to remedy this drawback by using at least one elastic pulley and sheath stops making it possible to ensure, by prestressing the sheaths enveloping the cable, a suitable tension of the cable maneuver. However, this solution causes inconvenience for the user (play before operation at the level of the operating crank and / or greater effort to be exerted on it approximately halfway) and causes premature wear of the lifter. glass due to exer tensions created on its various elements.

La présente invention se propose de remédier à ces inconvénients. L'invention a donc pour but un lève-vitre à câble dans lequel la tension du câble reste constante, qui soit de manipulation agréable pour l'utilisateur et dont la durée de vie soit prolongée par rapport aux lève-vitre à câble réalisés jusqu'à présent.The present invention proposes to remedy these drawbacks. The object of the invention is therefore to provide a cable window regulator in which the cable tension remains constant, which is pleasant to handle for the user and whose lifespan is extended compared to cable window regulators produced up to now.

Plus précisément, l'invention a pour objet un lève-vitre, notamment pour véhicule automobile, du type comportant une glissière courbe, un chariot solidaire d'une vitre et susceptible d'être déplacé le long de la glissière au moyen d'un câble passant sur deux poulies de renvoi et s'enroulant sur un tambour d'un treuil de manoeuvre.More specifically, the subject of the invention is a window lifter, in particular for a motor vehicle, of the type comprising a curved slide, a carriage secured to a window and capable of being moved along the slide by means of a cable. passing over two idler pulleys and winding on a drum of an operating winch.

Selon l'invention, le tambour du treuil présente une section transversale variable de façon que la longueur du câble enroulée varie en fonction de la position du chariot sur la glissière.According to the invention, the winch drum has a variable cross section so that the length of the coiled cable varies depending on the position of the carriage on the slide.

Dans un mode préféré de réalisation du lève-vitre selon l'invention, dans lequel le câble est constitué de deux brins fixés chacun à l'une des extrémités du tambour, ladite section transversale croit d'une extrémité du tambour jusqu'à un maximum correspondant au point de la glissière le plus éloigné d'un axe passant par les deux poulies puis décroit jusqu'à l'autre extrémité du tambour.In a preferred embodiment of the window regulator according to the invention, in which the cable consists of two strands each fixed to one of the ends of the drum, said cross section increases from one end of the drum to a maximum corresponding to the point of the slide furthest from an axis passing through the two pulleys then decreases to the other end of the drum.

De préférence, la forme du tambour est de révolution. Elle peut par exemple être bicônique.Preferably, the shape of the drum is of revolution. It can for example be biconic.

Mais, afin d'être mieux comprise, l'invention va maintenant être décrite de façon plus précise, en référence à quatre modes de réalisation, donnés uniquement à titre d'exemples et représentés par les dessins annexés, sur lesquels

  • - la Fig.1 représente une vue d'ensemble d'un premier mode de réalisation d'un lève-vitre selon l'invention, destiné à être utilisé dans une porte de véhicule automobile et dans. lequel le câble est constitué de deux brins fixés chacun à l'une des extrémités du tambour;
  • - la Fig.2 est une vue suivant la flèche F de la Fig.1, montrant le chariot dans deux positions différentes;
  • - la Fig.3 représente un détail du tambour du lève-vitre des Fig.1 et 2;
  • - les Fig.4 et 5 représentent, schématiquement, respectivement un deuxième et un troisième mode de réalisation d'un tambour d'un lève-vitre selon l'invention, dans lequel le câble est constitué de deux brins; et
  • - la Fig.6 représente, schématiquement, un quatrième mode de réalisation d'un tambour d'un lève-vitre selon l'invention, dans lequel le câble est constitué d'un brin unique.
However, in order to be better understood, the invention will now be described in more detail, with reference to four embodiments, given solely by way of examples and represented by the appended drawings, in which
  • - Fig.1 shows an overview of a first embodiment of a window regulator according to the invention, intended for use in a door of a motor vehicle and in. which the cable consists of two strands each attached to one end of the drum;
  • - Fig.2 is a view along arrow F of Fig.1, showing the carriage in two different positions;
  • - Fig.3 shows a detail of the window lifter drum of Fig.1 and 2;
  • - Fig.4 and 5 show, schematically, respectively a second and a third embodiment of a drum of a window regulator according to the invention, wherein the cable consists of two strands; and
  • - Fig.6 shows, schematically, a fourth embodiment of a drum of a window regulator according to the invention, in which the cable consists of a single strand.

Le lève-vitre représenté sur la Fig.1 comporte une glissière courbe 1, aux extrémités de laquelle sont fixées deux poulies 2 et 3. La glissière 1 est, de façon connue de l'homme du métier, constituée par un tube 4, comportant une lumière longitudinale 5 dans laquelle coulisse un chariot 6 solidaire d'un support 7 dans lequel est enserrée une vitre 8.The window regulator shown in Fig.1 has a curved slide 1, at the ends of which are fixed two pulleys 2 and 3. The slide 1 is, in a manner known to those skilled in the art, constituted by a tube 4, comprising a longitudinal slot 5 in which slides a carriage 6 secured to a support 7 in which a window 8 is enclosed.

Au chariot 6 sont fixés deux brins de câble, un brin supérieur S et un brin inférieur 1, qui passent respectivement sur les poulies de renvoi 2 et 3 et s'enroulent sur un tambour 9 d'un treuil de manoeuvre 10 comportant une manivelle 11. Les brins de câble S et I sont contenus dans des gaines 12 et 13 reliant les poulies 2 et 3 au treuil de manoeuvre 10. Ces brins S et I sont fixés chacun à l'une des extrémités du tambour 9, respectivement aux points A et B, comme cela est représenté sur la Fig.3.To the carriage 6 are fixed two strands of cable, an upper strand S and a lower strand 1, which pass respectively over the idler pulleys 2 and 3 and are wound on a drum 9 of an operating winch 10 comprising a crank 11 The cable strands S and I are contained in sheaths 12 and 13 connecting the pulleys 2 and 3 to the operating winch 10. These strands S and I are each attached to one end of the drum 9, respectively at points A and B, as shown in Fig.3.

On voit sur cette figure, que les brins S et I s'enroulent en sens inverse dans une gorge hélicoi- dale 14 ménagée à la surface du tambour 9 qui peut par exemple être de forme bicônique. En vue d'une meilleure compréhension, le pas de la gorge hélicoïdale a été agrandi sur la Fig.3. En réalité, les spires de la gorge 14 devraient se trouver côte à côte.It is seen from this figure that the S and I strands are wound in opposite directions in a helicoidal groove of ale 14 formed at the surface of the drum 9 which may for instance be of double-angled shape. For a better understanding, the pitch of the helical groove has been enlarged in Fig. 3. In reality, the turns of the groove 14 should be side by side.

Si l'on fait tourner le tambour 9 dans le sens indiqué par la flèche T, afin de baisser la vitre 8, le brin S se déroule, laissant libre à chaque tour, une spire 15 de la gorge hélicoïdale 14 sur laquelle vient s'enrouler le brin I. La spire libre 15 se déplace, au fur et à mesure que le tambour 9 tourne, de 8 vers A.If the drum 9 is rotated in the direction indicated by the arrow T, in order to lower the window 8, the strand S unrolls, leaving free at each turn, a turn 15 of the helical groove 14 on which comes s' wind the strand I. The free turn 15 moves, as the drum 9 rotates, from 8 to A.

Etant donné que le tambour 9 est de forme bicônique, la longueur de la spire libre 15 croit du point B jusqu'à un maximum situé à mi-course et correspondant au point de la glissière le plus éloigné d'un axe C-C (Fig.2) passant par les deux poulies, avant de décroitre jusqu'au point A. Cette variation de la longueur de la spire libre 15 permet de compenser la variation de la longueur de câble entre les deux poulies de renvoi 2 et 3, c'est à dire la variation de la somme des deux petits côtés S' et I'(Fig.2) d'un triangle variable dont les sommets sont constitués par les deux poulies 2 et 3 et le chariot 6. Ce triangle est représenté sur la Fig.2 qui montre le chariot 6 dans deux positions différentes : à mi-course en traits pleins et en fin de course en traits pointillés.Since the drum 9 is biconically shaped, the length of the free coil 15 increases from point B to a maximum located at mid-stroke and corresponding to the point of the slide furthest from a CC axis (Fig. 2) passing through the two pulleys, before decreasing to point A. This variation in the length of the free coil 15 makes it possible to compensate for the variation in the length of cable between the two return pulleys 2 and 3, this is ie the variation of the sum of the two short sides S 'and I' (Fig.2) of a variable triangle whose vertices are constituted by the two pulleys 2 and 3 and the carriage 6. This triangle is shown in Fig .2 which shows the carriage 6 in two different positions: halfway in solid lines and end of stroke in dotted lines.

Le câble du lève-vitre équipé d'un tambour tel que représenté sur la Fig.3, a une tension qui reste toujours constante lorsque l'on déplace le chariot d'une extrémité à l'autre de la glissière. L'effort exercer sur la manivelle est donc régulier, ce qui présente un avantage pour l'utilisateur. En outre, la durée de vie d'un tel lève-vitre est prolongée par rapport aux lève-vitre dans lesquels la tension du câble varie.The window regulator cable fitted with a drum te l as shown in Fig.3, has a tension which always remains constant when the carriage is moved from one end to the other of the slide. The effort exerted on the crank is therefore regular, which has an advantage for the user. In addition, the service life of such a window regulator is extended compared to window regulators in which the cable tension varies.

La forme du tambour 9 est bien sûr fonction de la courbure de la glissière. Le tambour 9 n'est donc pas obligatoirement symétrique par rapport à un plan perpendiculaire à son axe, comme le tambour représenté sur la Fig.3, il ne l'est que si l'ensemble, formé par la glissière et les poulies, est lui-même symétrique.The shape of the drum 9 is of course a function of the curvature of the slide. The drum 9 is therefore not necessarily symmetrical with respect to a plane perpendicular to its axis, like the drum shown in Fig.3, it is only if the assembly, formed by the slide and the pulleys, is itself symmetrical.

De préférence, la forme du tambour est de révolution afin de simplifier sa réalisation.Preferably, the shape of the drum is of revolution in order to simplify its production.

Les Fig.4 et 5 montrent deux variantes possibles de la forme du tambour, référencées respectivement par 16 et 17.Figs. 4 and 5 show two possible variants of the shape of the drum, referenced respectively by 16 and 17.

Sur ces figures, le tambour 16 (Fig.4) se présente sous la forme de deux parties évasées 16a et 16b reliées entre elles par leurs faces de plus grand diamètre et le tambour 17 (Fig.5), sous la forme d'un tonneau.In these figures, the drum 16 (Fig. 4) is in the form of two flared parts 16a and 16b connected together by their faces of larger diameter and the drum 17 (Fig. 5), in the form of a barrel.

Dans une autre variante de réalisation du lève-vitre selon l'invention, le câble pourrait être constitué d'un brin unique dont les deux extrémités seraient fixées de part et d'autre du chariot. La forme du tambour serait alors conçue de la même façon que précédemment de façon à enrouler le câble sur une spire légèrement plus petite ou légèrement plus grande que la spire d'où le câble se déroule; par exemple, le tambour pourrait se présenter sous la forme d'un dia- bolo 18 représenté sur la Fig.6 et sur lequel est enroulée une portion d'un câble 19, la portion de câble enroulé se déplaçant par exemple de l'extrémité 20 à l'extrémité 21 du tambour 18 quand on tourne celui-ci dans le sens de la flèche T'.In another alternative embodiment of the window regulator according to the invention, the cable could consist of a single strand, the two ends of which would be fixed on either side of the carriage. The shape of the drum would then be designed in the same way as previously so as to wind the cable on a slightly smaller or slightly larger turn than the turn from which the cable is unwound; for example, the drum could be in the form of a dia- b olo 18 shown in Fig.6 and on which a portion of a cable 19 is wound, the portion of wound cable moving for example from the end 20 to the end 21 of the drum 18 when it is rotated in the direction of arrow T '.

La section transversale du tambour décroit alors d'une extrémité de celui-ci jusqu'à un minimum correspondant au point de la glissière le plus éloigné de l'axe C-C passant par les deux poulies puis croit jusqu'à l'autre extrémité du tambour.The cross section of the drum then decreases from one end of the latter to a minimum corresponding to the point of the slide furthest from the axis CC passing through the two pulleys then increases to the other end of the drum .
