Description

La présente invention a pour objet un dispositif de sécurité pour lève-vitre électriques de véhicule, du type à câble d'entraînement de la vitre par un moteur, le câble passant autour d'une poulie de renvoi.The present invention relates to a safety device for electric vehicle window regulators, of the type with cable for driving the window by a motor, the cable passing around a return pulley.

On sait qu'il existe actuellement trois types de lève-vitre sur les véhicules automobiles : les lève-vitre à câble crémaillère, les lève-vitre à câble torsadé (câble Bowden), et les lève-vitre à bras et secteur denté. L'invention concerne les deux premiers types de lève-vitre.It is known that there are currently three types of window regulators on motor vehicles: window regulators with rack cable, window regulators with twisted cable (Bowden cable), and window regulators with arms and toothed sector. The invention relates to the first two types of window regulator.

Quand un obstacle se trouve sur le parcours de fermeture de la vitre, le système doit reconnaître la présence d'un phénomène anormal et, si l'effort sur la vitre dépasse une valeur limite, la vitre ne doit pas continuer sa trajectoire, mais s'arrêter et au moins libérer l'effort. Cette libération de l'effort peut être obtenue soit en libérant la vitre qui descend sous un faible effort ou sous l'effet de son propre poids si le frottement dans le joint latéral le permet, soit en inversant le mouvement de la vitre qui est alors forcée à descendre.When an obstacle is on the closing path of the window, the system must recognize the presence of an abnormal phenomenon and, if the force on the window exceeds a limit value, the window must not continue its trajectory, but s '' stop and at least release the effort. This release of the force can be obtained either by releasing the glass which descends under a weak force or under the effect of its own weight if the friction in the lateral joint allows it, or by reversing the movement of the glass which is then forced to descend.

Pour résoudre ce problème on a déjà proposé divers dispositifs de sécurité, électriques et électromécaniques, qui présentent, entre autres inconvénients, celui d'être relativement onéreux en raison de leur complexité. Ce coût de fabrication élevé est évidemment un obstacle à leur diffusion en grande série.To solve this problem, various safety devices, electrical and electromechanical, have already been proposed, which have, among other disadvantages, that of being relatively expensive because of their complexity. This high manufacturing cost is obviously an obstacle to their dissemination in large series.

L'invention a pour but de proposer un dispositif de sécurité électromécanique pour les lève-vitre à câble, qui soit de fabrication simple et par conséquent peu coûteuse.The object of the invention is to propose an electromechanical safety device for cable window regulators, which is simple to manufacture and therefore inexpensive.

Suivant l'invention, le dispositif de sécurité comprend des moyens électromécaniques de détection et de mesure de l'effort exercé sur la vitre et transmis au câble, tels qu'ils inversent automatiquement le sens de rotation du moteur lorsque cet effort dépasse une valeur limite prédéterminée.According to the invention, the safety device comprises electromechanical means for detecting and measuring the force exerted on the window and transmitted to the cable, such that they automatically reverse the direction of rotation of the motor when this force exceeds a limit value predetermined.

Suivant un mode de réalisation de l'invention, lesdits moyens comprennent un ressort de compression prenant appui d'une part sur un support fixe, d'autre part sur un élément susceptible d'être déplacé par le câble par friction contre celui-ci et à l'encontre de la force de rappel du ressort, et un interrupteur électrique coopérant avec ledit élément de façon à pouvoir prendre un premier état lorsque l'effort d'entraînement dudit élément par le câble reste inférieur à ladite valeur prédéterminée, et à prendre un second état lorsque cet effort d'entraînement dépasse ladite valeur prédéterminée.According to one embodiment of the invention, said means comprise a compression spring bearing on the one hand on a fixed support, on the other hand on an element capable of being displaced by the cable by friction against the latter and against the return force of the spring, and an electric switch cooperating with said element so as to be able to assume a first state when the force for driving said element by the cable remains below said predetermined value, and to be taken a second state when this training effort exceeds said predetermined value.

L'interrupteur électrique fait partie d'un circuit d'alimentation et de commande du moteur, capable d'inverser son sens de rotation de manière connue en soi.The electric switch is part of a motor supply and control circuit, capable of reversing its direction of rotation in a manner known per se.

Un tel dispositif de sécurité est de structure relativement simple et par conséquent peu onéreuse.Such a safety device is relatively simple in structure and therefore inexpensive.

L'invention sera maintenant décrite en référence au dessin annexé qui en illustre deux formes de réalisation à titre d'exemples non limitatifs.The invention will now be described with reference to the accompanying drawing which illustrates two embodiments thereof by way of nonlimiting examples.

  • La figure 1 est une vue en élévation schématique partielle d'un lève-vitre électrique à câble torsadé ou câble Bowden, équipé d'un dispositif de sécurité selon une première forme de réalisation de l'invention.Figure 1 is a partial schematic elevational view of an electric window regulator with twisted cable or Bowden cable, equipped with a safety device according to a first embodiment of the invention.
  • La figure 2 est une vue mi-coupe mi-élévation partielle, à échelle agrandie, montrant le dispositif de sécurité de la Fig.1.Figure 2 is a partial sectional mid-elevation view, on an enlarged scale, showing the safety device of Fig.1.
  • La figure 3 est une vue analogue à la Fig.1 illustrant une seconde forme de réalisation de la sécurité selon l'invention.Figure 3 is a view similar to Fig.1 illustrating a second embodiment of security according to the invention.

Le lève-vitre 1 représenté à la Fig.1 comprend un motoréducteur 2 d'entraînement d'un câble torsadé ou câble Bowden 3, passant autour de deux poulies 4, 5 de renvoi. Le brin du câble 3 situé entre ces deux poulies s'étend le long d'un rail 6 de guidage, et porte un chariot 7 qui supporte la vitre (non représentée).The window regulator 1 shown in Fig.1 comprises a geared motor 2 for driving a twisted cable or Bowden cable 3, passing around two pulleys 4, 5 for returning. The strand of cable 3 located between these two pulleys extends along a guide rail 6, and carries a carriage 7 which supports the glass (not shown).

La poulie supérieure 4 est montée sur une plaque fixe 8 sur laquelle est fixée une gaine 9 s'étendant sur une longueur appropriée autour du câble 3. A l'intérieur de la gaine 9 est disposé un ressort hélicoïdal 11 coaxial au câble 3, dont une extrémité prend appui sur la plaque fixe 9 et l'extrémité opposée prend appui sur un élément 12 susceptible d'être déplacé par le câble 3 par friction contre celui-ci, à l'encontre de la force de rappel du ressort 11. Dans l'exemple décrit, cet élément 12 est une pièce tubulaire pouvant coulisser à l'intérieur de la gaine 9, coaxiale au câble 3 et pourvue d'une patte latérale 13 coopérant avec le contact d'un interrupteur électrique 14 monté sur un support fixe 15, tel que le panneau de porte (non représenté).The upper pulley 4 is mounted on a fixed plate 8 on which is fixed a sheath 9 extending over an appropriate length around the cable 3. Inside the sheath 9 is disposed a helical spring 11 coaxial with the cable 3, of which one end is supported on the fixed plate 9 and the opposite end is supported on an element 12 capable of being displaced by the cable 3 by friction against the latter, against the return force of the spring 11. In the example described, this element 12 is a tubular part which can slide inside the sheath 9, coaxial with the cable 3 and provided with a lateral tab 13 cooperating with the contact of an electric switch 14 mounted on a fixed support 15, such as the door panel (not shown).

Le ressort 11 agissant par compression avec une précontrainte déterminée, le fonctionnement de cette sécurité est le suivant : tant que l'effort que doit transmettre le câble 3 au chariot 7 et à la vitre pour faire monter celle-ci ne dépasse pas une valeur prédéterminée, correspondant à la force de précontrainte du ressort 11, celui-ci maintient la pièce tubulaire 12 dans une position telle que sa patte 13 actionne l'interrupteur de pesage 14. Si par contre, par suite de l'interposition d'un obstacle sur la trajectoire de fermeture de la vitre, l'effort F que le câble 3 doit transmettre dépasse la limite fixée par la précontrainte du ressort 11, la pièce tubulaire 12 coulisse dans la gaine 9 à l'encontre de la force de rappel du ressort 11 qui est ainsi comprimé. Corrélativement ce déplacement écarte la pièce 12 et la patte 13 de l'interrupteur 14 qui n'est plus actionné. Ce changement d'état de l'interrupteur déclenche une commande d'inversion du sens de rotation du moteur du motoréducteur 2 par le circuit électrique d'alimentation de ce dernier, dont fait partie l'interrupteur de pesage 14.The spring 11 acting by compression with a determined prestress, the operation of this security is as follows: as long as the force which the cable 3 has to transmit to the carriage 7 and to the window pane to raise the latter does not exceed a predetermined value , corresponding to the prestressing force of the spring 11, the latter maintains the tubular part 12 in a position such that its lug 13 actuates the weighing switch 14. If on the other hand, following the interposition of an obstacle on the window closing path, the force F that the cable 3 must transmit exceeds the limit set by the preload of the spring 11, the tubular part 12 slides in the sheath 9 against the return force of the spring 11 which is thus compressed. Correlatively this movement separates the part 12 and the tab 13 of the switch 14 which is no longer actuated. This change of state of the switch triggers a command to invert the direction of rotation of the motor of the gearmotor 2 by the electrical supply circuit of the latter, of which the weighing switch 14 is a part.

Ce type de dispositif de sécurité nécessite un circuit électrique à mémoire électrique, car il revient de manière quasi immédiate à sa position de départ après détection et inversion du sens du mouvement.This type of safety device requires an electrical circuit with an electrical memory, since it returns almost immediately to its starting position after detection and reversal of the direction of movement.

Dans la forme de réalisation représentée à la Fig.3, l'invention est également appliquée à un lève-vitre 1 du type à câble torsadé 3, mais celui-ci est modifié de la manière suivante. La poulie supérieure 7 est montée à l'extrémité d'un levier 16 articulé autour d'un axe 19 sur un organe fixe, à savoir dans l'exemple représenté le panneau de porte 17. Les moyens électromécaniques de la sécurité selon l'invention comprennent également des moyens élastiques de maintien du levier 6 et de la poulie 4 dans une position angulaire déterminée. Ces moyens sont constitués, dans l'exemple décrit, par un ressort 18 de compression dont une extrémité est fixée au levier 16 et l'autre extrémité est fixée au panneau 17. Le ressort 18 agit sur la partie du levier 16 située du côté de l'axe 19 opposée à la poulie 4.In the embodiment shown in FIG. 3, the invention is also applied to a window regulator 1 of the twisted cable type 3, but this is less defined as follows. The upper pulley 7 is mounted at the end of a lever 16 articulated around an axis 19 on a fixed member, namely in the example shown the door panel 17. The electromechanical safety means according to the invention also include elastic means for holding the lever 6 and the pulley 4 in a determined angular position. These means consist, in the example described, of a compression spring 18, one end of which is fixed to the lever 16 and the other end of which is fixed to the panel 17. The spring 18 acts on the part of the lever 16 situated on the side of the axis 19 opposite the pulley 4.

La sécurité électromécanique selon l'invention comporte enfin un interrupteur électrique 21 fixé par exemple sur le support 17, et positionné de manière à pouvoir coopérer avec l'extrémité du levier 16 opposée à la poulie 4. L'interrupteur 21 fait partie d'un circuit de commande connu en soi, non représenté, à mémoire électrique comme celui associé à la sécurité des Fig.1 et 2. Il coopère avec le levier 16 de manière à être dans un premier état, lorsqu'il est actionné, tant que le levier 16 et la poulie 4 restent dans une position angulaire déterminée par la force de compression du ressort 18, qui exerce sur le levier 16 un effort tendant à maintenir la poulie 4 en position haute et le câble 3 tendu. L'interrupteur 21 passe dans un second état lorsqu'il n'est plus actionné du fait que le levier 16 ainsi que la poulie 4 basculent sous l'effet d'un effort, exercé sur la vitre, dépassant la valeur limite résultant de la compression du ressort 18 et de son bras de levier par rapport à l'axe de basculement 19. En effet l'extrémité du levier 16 s'écarte alors de l'interrupteur 21, la poulie 4 s'abaisse en 4a et le levier 16 bascule jusqu'à la position 16a. Le circuit électrique dont fait partie l'interrupteur 21 commande automatiquement l'inversion du sens de rotation du moteur du motoréducteur 2.The electromechanical safety device according to the invention finally comprises an electrical switch 21 fixed for example on the support 17, and positioned so as to be able to cooperate with the end of the lever 16 opposite the pulley 4. The switch 21 is part of a control circuit known per se, not shown, with electric memory like that associated with the safety of FIGS. 1 and 2. It cooperates with the lever 16 so as to be in a first state, when it is actuated, as long as the lever 16 and the pulley 4 remain in an angular position determined by the compression force of the spring 18, which exerts on the lever 16 an effort tending to maintain the pulley 4 in the high position and the cable 3 stretched. The switch 21 goes into a second state when it is no longer actuated owing to the fact that the lever 16 as well as the pulley 4 tilt under the effect of a force, exerted on the glass, exceeding the limit value resulting from the compression of the spring 18 and of its lever arm with respect to the tilting axis 19. In fact the end of the lever 16 then departs from the switch 21, the pulley 4 lowers at 4a and the lever 16 switches to position 16a. The electrical circuit of which the switch 21 is a part automatically controls the reversal of the direction of rotation of the motor of the geared motor 2.

L'invention n'est pas limitée aux modes de réalisations décrits et peut comporter diverses variantes d'exécution. De manière générale l'invention couvre tous moyens équivalents à ceux décrits, c'est-à-dire pouvant effectuer un pesage sur le câble de l'effort sur la vitre. En effet, cet effort est transmis au câble 3 via le chariot 7, de sorte que l'effort sur le câble donne une bonne image de l'effort sur la vitre.The invention is not limited to the embodiments described and may include various variant embodiments.
