Description

L'invention concerne les lève-vitres pour automobiles et plus particulièrement les lève-vitres pour automobiles à renvois de câble.The invention relates to window lifts for automobiles and more particularly window lifts for cars with cable returns.

Le document EP-A-139 269 décrit un lève-vitre selon le préambule de la revendication 1 avec une plaque sur laquelle sont disposées une poulie de guidage et une gorge de guidage à une partie supérieure de la plaque. Le document US-A-4 428 542 décrit un lève-vitre avec un premier et deuxième renvois disposés à une extrémité d'un rail de guidage dans un boítier de guidage de câble.EP-A-139 269 discloses a window regulator according to the preamble of claim 1 with a plate on which there is arranged a guide pulley and a guide groove at an upper part of the plate. US-A-4 428 542 discloses a window regulator with a first and second references disposed at one end of a guide rail in a housing of cable guide.

Le document US-4 910 917 décrit un lève-vitre à câble. Ce lève-vitre comprend deux rails non parallèles, guidant deux curseurs respectifs suivant une course de déplacement de vitre. Chaque curseur est entraíné par un câble Bowden. Chaque curseur présente deux parties. Une première partie est guidée par le rail et une deuxième partie est fixée à la vitre. Les deux parties coulissent relativement l'une par rapport à l'autre en translation et en rotation. Ce dispositif permet de régler la position relative des deux parties pour éviter un arc-boutement de la vitre dans un cadre de vitre.US-4,910,917 discloses a cable lifter. This window regulator includes two non-parallel rails, guiding two respective sliders following a window movement. Each cursor is driven by a Bowden cable. Each cursor has two parts. A first part is guided by rail and a second part is fixed to the window. Both parts slide relatively relative to each other in translation and rotation. This device makes it possible to the relative position of the two parts to avoid an arching of the glass in a window frame.

Ce dispositif présente des inconvénients. Ce dispositif occupe une surface importante en projection sur le plan moyen de la vitre. Ce dispositif nécessite également l'emploi de deux rails de guidage.This device has disadvantages. This device occupies a surface significant projection on the average plane of the glass. This device requires also the use of two guide rails.

Il existe donc un besoin pour un lève-vitre résolvant un ou plusieurs de ces inconvénients.There is therefore a need for a window regulator solving one or more of these disadvantages.

L'invention a ainsi pour objet un lève-vitre, comprenant :

  • un élément de liaison de vitre ;
  • un élément moteur d'entraínement de câble, désaxé par rapport à la course de l'élément de liaison ;
  • des premier et deuxième renvois de câble disposés à une extrémité de la course de l'élément de liaison et superposés, lorsqu'ils sont considérés selon une direction normale au plan de renvoi, le plan de renvoi incluant les parties de câble entrant et sortant du renvoi;
  • un troisième renvoi de câble disposé à une autre extrémité de la course de l'élément de liaison ;
  • un câble solidaire de l'élément de liaison de vitre.
The invention thus relates to a window regulator, comprising:
  • a glass connecting element;
  • a cable drive motor element, offset with respect to the travel of the connecting element;
  • first and second cable returns disposed at one end of the travel of the connecting element and superimposed, when considered in a direction normal to the plane of return, the return plane including the cable parts entering and leaving the return;
  • a third cable return disposed at another end of the travel of the connecting element;
  • a cable secured to the glass connecting element.

Selon une variante, le câble est guidé successivement par le premier renvoi, l'élément moteur, le deuxième renvoi et le troisième renvoi.According to one variant, the cable is successively guided by the first return, the driving element, the second return and the third return.

Selon encore une variante, l'un parmi les premier et deuxième renvois est une poulie.According to another variant, one of the first and second references is a pulley.

Selon une autre variante, les premier et deuxième renvois sont des poulies.According to another variant, the first and second references are pulleys.

Selon encore une autre variante, les première et deuxième poulies sont montées à rotation autour d'un même axe.According to yet another variant, the first and second pulleys are mounted rotating around the same axis.

On peut encore prévoir que la poulie présente deux gorges formant respectivement premier et deuxième renvois.It can also be provided that the pulley has two grooves forming respectively first and second references.

Selon une variante, les deux poulies ou gorges ont des diamètres différents. According to one variant, the two pulleys or grooves have different diameters.

Selon une autre variante, le diamètre d'une poulie ou gorge est défini de sorte que le câble entre cette poulie ou gorge et le troisième renvoi reste parallèle au déplacement de l'élément de liaison.According to another variant, the diameter of a pulley or groove is defined so that that the cable between this pulley or groove and the third return remains parallel to the displacement of the connecting element.

Selon encore une variante, le diamètre de l'autre poulie ou gorge est défini de sorte que le câble entre l'autre poulie ou gorge et l'élément de liaison reste parallèle au déplacement de l'élément de liaison.According to another variant, the diameter of the other pulley or groove is defined by so that the cable between the other pulley or groove and the connecting element remains parallel moving the connecting element.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description qui suit de modes de réalisation de l'invention, donnée à titre d'exemple et en référence aux dessins annexés qui montrent :

  • figure 1, une représentation schématique d'un exemple de lève-vitre selon l'invention ;

  • figure 3, une vue de face en section transversale de détails du lève-vitre de la figure 1 ;
  • figure 4, une vue de dessus de détails du lève-vitre de la figure 1.
Other features and advantages of the invention will appear on reading the following description of embodiments of the invention, given by way of example and with reference to the appended drawings which show:
  • Figure 1, a schematic representation of an example of a window lifter according to the invention;
  • Figure 2 is a cross-sectional view of a double reference of Figure 1;
  • Figure 3 is a front view in cross-section of details of the window lifter of Figure 1;
  • Figure 4 is a top view of details of the window lifter of Figure 1.

L'invention porte sur un lève-vitre présentant un élément de liaison, un élément moteur désaxé par rapport à la course de l'élément moteur, et deux renvois superposés disposés à une extrémité de la course.The invention relates to a window regulator having a connecting element, an element off-axis motor with respect to the stroke of the driving element, and two references superimposed arranged at one end of the race.

Dans la suite, deux renvois superposés doivent être interprétés comme deux renvois se recouvrant au moins partiellement, lorsqu'ils sont considérés selon une direction normale au plan du renvoi, et dont les plans sont sensiblement parallèles mais distincts. On définit le plan d'un renvoi par le plan qui inclut les parties de câble entrant et sortant d'un renvoi.In the following, two overlapping references must be interpreted as two overlapping references at least partially when considered in accordance with normal direction to the plane of reference, and whose plans are substantially parallel but distinct. The plane of a reference is defined by the plane which includes the parts of cable entering and leaving a referral.

Les figures 1 à 4 représentent un exemple de lève-vitre 1 selon l'invention. Ce lève-vitre 1 comprend notamment un élément de liaison de vitre 2. Une vitre à déplacer, représentée en trait mixte sur les figures 1 et 3, est solidarisée à l'élément de liaison 2. L'élément de liaison de vitre est monté à coulissement par rapport à un rail de guidage 8. Un câble 7 présente deux extrémités 9 et 10 solidarisées à l'élément de liaison respectivement par la partie inférieure et la partie supérieure. Le lève-vitre présente un renvoi 5 disposé à une extrémité de la course de l'élément de liaison et deux renvois superposés 3 et 4 disposés à l'autre extrémité de la course de l'élément de liaison. Un élément moteur 6 entraínant le câble est disposé désaxé par rapport à la course de l'élément de l'élément de liaison 2. Un système de tension de câble non représenté peut être mis en place pour maintenir le câble sous tension.Figures 1 to 4 show an example of window lifter 1 according to the invention. This window regulator 1 comprises in particular a glass connecting element 2. A window pane move, shown in phantom in Figures 1 and 3, is secured to the element 2. The glass connecting element is slidably mounted with respect to a guide rail 8. A cable 7 has two ends 9 and 10 secured to the connecting element respectively by the lower part and the upper part. The window regulator has a reference 5 disposed at one end of the race of the element of link and two superposed references 3 and 4 arranged at the other end of the race of the connecting element. A motor element 6 driving the cable is disposed off-center by relative to the travel of the element of the connecting element 2. A tension system of Cable not shown can be put in place to keep the cable powered.

Le renvoi 3 dévie la trajectoire de l'extrémité de câble 9 qui est destinée à appliquer un effort de descente sur l'élément de liaison 2. Le renvoi 4 dévie la trajectoire de l'extrémité de câble 10 qui est destinée à appliquer un effort de montée sur l'élément de liaison. Les renvois 3 et 4 sont superposés. Ainsi, l'encombrement du lève-vitre dans le plan moyen défini par le câble est réduit. De plus, lorsque l'élément moteur comprend un tambour d'enroulement présentant une gorge hélicoïdale, il peut être particulièrement avantageux d'utiliser des renvois superposés. En disposant les renvois 3 et 4 superposés en vis-à-vis des parties de câble sortant de la gorge, les parties de câble sortant de la gorge peuvent s'étendre avec une moindre déviation de trajectoire jusqu'aux renvois respectifs 3 ou 4. Le câble est alors moins sollicité dans la direction normale au plan des renvois, ce qui réduit le frottement du câble sur les renvois.The reference 3 deflects the trajectory of the cable end 9 which is intended to apply a descent force on the connecting element 2. The return 4 deflects the trajectory of the cable end 10 which is intended to apply a climbing force on the connecting element. References 3 and 4 are superimposed. So, the clutter the window lifter in the middle plane defined by the cable is reduced. In addition, when the motor element comprises a winding drum having a throat helically, it may be particularly advantageous to use superposed references. By arranging the references 3 and 4 superimposed vis-à-vis the parts of cable coming out of the throat, the cable parts coming out of the throat can expand with less trajectory deviation up to the respective references 3 or 4. The cable is then less biased in the normal direction in terms of returns, which reduces the friction of the cable on the referrals.

Dans l'exemple représenté, le câble est fixé par son extrémité 10 à l'élément de liaison de vitre 2, puis passe successivement par le renvoi 5, par le renvoi 4, par l'élément moteur 6, par le renvoi 3 et se fixe par son extrémité 9 sur l'élément de liaison 2. Les trois parties de câble disposées sur la course de l'élément de liaison, c'est-à-dire entre les renvois 5 et 3-4, occupent ainsi un volume particulièrement compact, ce qui permet de libérer de la place par exemple dans une portière dans laquelle le lève-vitre peut être monté. Dans cet agencement, et du fait que les renvois 3 et 4 sont superposés, les parties du câble s'étendant entre l'élément moteur et les renvois 3 et 4 occupent également un espace particulièrement compact.In the example shown, the cable is fixed by its end 10 to the element of window link 2, then passes successively by the reference 5, by the reference 4, by the motor element 6, by the reference 3 and is fixed by its end 9 on the element of link 2. The three cable parts arranged on the path of the connecting element, that is between the references 5 and 3-4, thus occupy a particular volume compact, which allows to free up space for example in a door in which the window regulator can be mounted. In this arrangement, and the fact that references 3 and 4 are superimposed, the parts of the cable extending between the motor element and the References 3 and 4 also occupy a particularly compact space.

Dans une variante avantageuse de l'invention, au moins un des renvois 3 ou 4 est réalisé sous forme de poulie. En montant par exemple une telle poulie à rotation par rapport à une partie structurelle 11 du lève-vitre, les frottements entre la poulie et le câble qu'elle guide sont réduits.In an advantageous variant of the invention, at least one of the references 3 or 4 is in the form of a pulley. By mounting for example such a rotating pulley relative to a structural part 11 of the window regulator, the friction between the pulley and the cable it guides are reduced.

Comme représenté à la figure 2, on peut également prévoir d'utiliser deux renvois 3 et 4 sous forme de poulies. Il est alors préférable d'utiliser un axe commun aux poulies. On peut par exemple prévoir de monter les poulies 3 et 4 autour d'un même arbre 12 les guidant à rotation. La structure et le montage du lève-vitre sont ainsi simplifiés. Bien qu'on ait représenté des poulies 3 et 4 ayant un axe commun, on peut également envisager des poulies ayant des axes respectifs décalés. On peut par exemple prévoir de monter les poulies 3 et 4 à rotation autour d'arbres respectifs.As shown in FIG. 2, it is also possible to use two referrals 3 and 4 in the form of pulleys. It is then preferable to use a common axis pulleys. For example, it is possible to mount the pulleys 3 and 4 around a same shaft 12 guiding them to rotation. The structure and assembly of the window regulator are thus simplified. Although pulleys 3 and 4 having a common axis have been shown, it is also possible to consider pulleys having respective offset axes. We can for example, to plan the pulleys 3 and 4 to rotate around respective shafts.

Dans l'exemple représenté, les poulies 3 et 4 présentent des diamètres différents. La poulie 3 présente ainsi un diamètre inférieur au diamètre de la poulie 4. Ainsi, la partie du câble s'étendant entre le renvoi 4 et le renvoi 5 peut passer hors du volume balayé par l'élément de liaison lors de sa course. On évite ainsi des frottements entre le câble et l'élément de liaison.In the example shown, the pulleys 3 and 4 have diameters different. The pulley 3 thus has a diameter smaller than the diameter of the pulley 4. Thus, the portion of the cable extending between the return 4 and the return 5 can pass out of volume swept by the connecting element during its course. This avoids friction between the cable and the connecting element.

Dans l'exemple représenté, on utilise un rail de guidage présentant une rainure de guidage de l'élément de liaison. Comme on peut le voir sur la figure 1, la partie du câble entre les renvois 4 et 5, ainsi que la partie du câble entre le renvoi 5 et l'élément de liaison restent comprises dans le volume de la fente du rail. Ces parties de câble sont ainsi protégées par le rail et disposées dans un volume compact. Cette protection permet avantageusement de se passer de gaine.In the example shown, a guide rail having a groove is used guiding the connecting element. As can be seen in Figure 1, the part of cable between the cross-references 4 and 5, as well as the part of the cable between the connecting element remain in the volume of the slot of the rail. These parts cable are thus protected by the rail and arranged in a compact volume. This protection advantageously makes it possible to do without sheath.

On peut encore prévoir d'utiliser des poulies 3 et 4 dont une seule est montée à rotation par rapport à la structure du lève-vitre 11, tandis que l'autre poulie est fixe. On peut également prévoir une unique poulie à deux gorges pour réduire le nombre de composants du lève-vitre. On monte alors la poulie à rotation par rapport à la structure du lève-vitre. La poulie tournera alors dans le même sens qu'une première partie du câble qu'elle guide et dans le sens inverse d'une autre partie de câble qu'elle guide. La poulie est de préférence prévue pour tourner dans le même sens que la partie de câble destinée à exercer un effort de montée sur l'élément de liaison.It is also possible to use pulleys 3 and 4, of which only one is mounted rotation relative to the structure of the window lifter 11, while the other pulley is fixed. One can also provide a single pulley with two grooves to reduce the number components of the window regulator. The rotational pulley is then mounted relative to the structure of the window regulator. The pulley will then rotate in the same direction as a first part of the cable that it guides and in the opposite direction of another part of cable that she guides. The pulley is preferably designed to rotate in the same direction as the portion of cable intended to exert a mounting force on the connecting element.

On peut également superposer un renvoi sous forme de poulie montée à rotation et un renvoi fixe par rapport à la structure. On peut alors, le cas échéant utiliser un élément du rail comme renvoi de câble. La poulie est de préférence utilisée pour guider le câble exerçant l'effort de montée sur l'élément de liaison.It is also possible to superimpose a pulley rotation and a fixed return relative to the structure. We can then, if necessary use a rail element as a cable return. The pulley is preferably used to guide the cable exerting the climbing force on the connecting element.

La figure 3 représente des détails de l'élément de liaison 2. L'élément de liaison 2 présente des éléments de fixation 13 et 14 pour fixer respectivement les extrémités de câble 9 et 10. La distance entre les éléments de fixation 13 et 14, en projection sur une droite perpendiculaire à la course de l'élément de liaison comprise dans un plan d'un renvoi, est sensiblement égale à la distance suivant la même projection entre un point de fin de contact du renvoi 3 avec le câble et un point de fin de contact du renvoi 5 avec le câble. Ainsi, les parties de câble s'étendant respectivement entre le renvoi 3 et l'élément de liaison 2 et entre le renvoi 5 et l'élément de liaison 2, restent parallèles durant le déplacement du curseur. On réduit ainsi le débattement du câble. L'usure et le bruit du câble sont ainsi réduits.FIG. 3 shows details of the connecting element 2. The element of connection 2 has fastening elements 13 and 14 for fixing respectively the cable ends 9 and 10. The distance between the fastening elements 13 and 14, in projection on a line perpendicular to the course of the connecting element in a plane of a reference, is substantially equal to the distance following the same projection between a point of contact 3 contact end with the cable and an end point Contact 5 contact with the cable. Thus, the cable parts extending respectively between the reference 3 and the connecting element 2 and between the reference 5 and the connecting element 2, remain parallel during the movement of the cursor. We reduce thus the deflection of the cable. The wear and noise of the cable are thus reduced.

Bien que dans l'exemple représenté on fasse usage d'un rail de guidage, on peut bien entendu prévoir dans le cadre de l'invention que le lève-vitre soit exempt de rail. On peut ainsi prévoir de guider l'élément de liaison par une tension adéquate des parties du câble s'étendant entre les poulies 5 et 3-4.Although in the example shown use is made of a guide rail, can of course provide in the context of the invention that the window regulator is exempt of rail. It is thus possible to guide the connecting element by adequate tension portions of the cable extending between the pulleys 5 and 3-4.

Par ailleurs, bien qu'on ait décrit un seul élément de liaison de vitre dans le lève-vitre présenté, on peut également prévoir un deuxième élément de liaison présentant une course sensiblement parallèle à celle de l'élément de liaison décrit. On peut ainsi prévoir qu'un autre câble entraínant l'autre élément de liaison soit également accouplé à l'élément moteur 6.On the other hand, although only one window connection element has been described in the presented window lifter, it is also possible to provide a second connecting element having a travel substantially parallel to that of the connecting element described. We can thus provide that another cable driving the other connecting element is also coupled to the driving element 6.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art et telles que définies dans les revendications jointes. On peut ainsi prévoir que le câble 7 soit divisé en plusieurs câbles indépendants. On peut prévoir d'accoupler les câbles indépendants par exemple au niveau de l'élément moteur.Of course, the present invention is not limited to the examples and modes of embodiment described and shown, but it is capable of many variants accessible to those skilled in the art and as defined in the appended claims. It can thus be provided that the cable 7 is divided into several independent cables. It is possible to couple the independent cables for example at the motor element.
