Balancing device for rear flap (1) of a motor vehicle, said flap being articulated, at its upper part, to the structure (2) of the vehicle around a horizontal axis (3) and comprising at least one balancing member such as an air spring (5) articulated on the one hand to the structure (2), on the other hand to the flap (1), characterized in that the air spring (5) is articulated on the flap (1) or on the structure (2), by means of a first lever (9) on which is articulated a first end of a link (12) whose second end is articulated on a second lever (15), at a point intermediate between an articulation (16) of said second lever (15) on the flap (1) (or the structure) and a roller (17) cooperating, in the vicinity of the closed position of the flap (1) with the structure (2) or with the flap (1). This very simple device has better efficiency than known devices, whatever the configuration of the flap (1).Description
L'invention se rapporte à un dispositif assurant l'équilibrage d'un volet ouvrant disposé à l'arrière d'un véhicule automobile sur la structure duquel il est articulé, à sa partie haute, autour d'un axe horizontal.The invention relates to a device ensuring the balancing of an opening flap disposed at the rear of a motor vehicle on the structure of which it is articulated, in its upper part, around a horizontal axis.
Il est connu de réaliser cet équilibrage à l'aide d'un ou deux organes tels que des ressorts pneumatiques articulés d'une part sur la structure et d'autre part sur le volet. De préférence, ces organes sont disposés sur les côtés du volet, dans des gouttières latérales. Ces organes ont pour rôle d'exercer, sur le volet, un couple qui s'oppose au couple dû à son poids, ce qui facilite son ouverture et assure son maintien en position ouverte.It is known to carry out this balancing using one or two members such as pneumatic springs articulated on the one hand on the structure and on the other hand on the flap. Preferably, these members are arranged on the sides of the flap, in lateral gutters. These organs have the role of exerting, on the shutter, a couple which opposes the couple due to its weight, which facilitates its opening and ensures that it is kept in the open position.
Malheureusement, la disposition de ces ressorts dans les gouttières latérales fait que, en partant de la position volet fermé, leur ligne d'action passe très près de l'axe d'articulation du volet, si bien que le couple exercé est très notoirement inférieur au couple opposé dû au poids du volet, de sorte que l'utilisateur est obligé d'exercer un effort manuel non négligeable en début d'ouverture.Unfortunately, the arrangement of these springs in the lateral gutters means that, starting from the closed shutter position, their line of action passes very close to the axis of articulation of the shutter, so that the torque exerted is very notoriously lower to the opposite torque due to the weight of the flap, so that the user is forced to exert a considerable manual effort at the start of opening.
C'est pourquoi on a déjà proposé de monter ces organes d'équilibrage par l'intermédiaire de leviers et de cames, de sorte que l'effort qu'ils exercent puisse être mieux utilisé pour aider le début d'ouverture du volet.This is why it has already been proposed to mount these balancing members by means of levers and cams, so that the force which they exert can be better used to assist the start of opening of the shutter.
Cependant, pour certaines configurations du volet (dimensions, poids, inclinaison en position fermée), les dispositifs connus, ou bien sont trop encombrants, ou bien ne permettent pas d'exercer un couple suffisant sur un angle d'ouverture assez grand du volet.However, for certain configurations of the shutter (dimensions, weight, inclination in the closed position), the known devices either are too bulky, or else do not make it possible to exert sufficient torque over a fairly large opening angle of the shutter.
L'invention a pour but de fournir un dispositif qui, tout en restant simple, présente une meilleure efficacité que les dispositifs connus, et ceci quelle que soit la configuration du volet.The object of the invention is to provide a device which, while remaining simple, has better efficiency than known devices, regardless of the configuration of the shutter.
L'invention concerne donc un dispositif d'équilibrage pour volet arrière de véhicule automobile, ledit volet étant articulé, à sa partie haute, à la structure du véhicule autour d'un axe horizontal et comprenant au moins un organe d'équilibrage tel qu'un ressort pneumatique articulé d'une part à la structure, d'autre part au volet.The invention therefore relates to a balancing device for a rear shutter of a motor vehicle, said shutter being articulated, at its upper part, to the structure of the vehicle around a horizontal axis and comprising at least one balancing member such as an air spring articulated on the one hand to the structure, on the other hand to the flap.
Ce dispositif est caractérisé en ce que le ressort pneumatique est articulé sur le volet (ou la structure) par l'intermédiaire d'un premier levier sur lequel est articulée une première extrémité d'une biellette dont la seconde extrémité est articulée sur un deuxième levier, en un point intermédiaire entre une articulation du dit deuxième levier sur le volet (ou la structure) et un galet coopérant, au voisinage de la position de fermeture du volet, avec la structure (ou le volet).This device is characterized in that the pneumatic spring is articulated on the flap (or the structure) by means of a first lever on which is articulated a first end of a rod whose second end is articulated on a second lever , at an intermediate point between an articulation of said second lever on the flap (or the structure) and a roller cooperating, in the vicinity of the closed position of the flap, with the structure (or the flap).

- - la Fig. 5 est un diagramme illustrant le couple auquel est soumis le volet en fonction de son angle d'ouverture.
- - Fig. 1 is a schematic vertical sectional view, parallel to the axis of the vehicle, of a rear flap fitted with a balancing device according to the invention seen in elevation;
- - Fig. 2 is a partial view, on a larger scale, of the device shown in FIG. 1, the shutter being closed;
- - Fig. 3 is a view similar to FIG. 2, the flap being partially open;

On voit, sur la Fig. 1, un volet arrière 1 de véhicule automobile, articulé à sa partie haute sur la structure 2 autour d'un axe transversal horizontal 3. Ce volet 1 est maintenu en position fermée par une serrure 4.We see in Fig. 1, a
Sur au moins un côté du volet 1, un organe d'équilibrage constitué, par exemple, par un ressort pneumatique 5, facilite l'ouverture du volet 1 et assure son maintien en position ouverte. Ce ressort 5, disposé dans une gouttière latérale 6 (Fig. 4), est relié, par une première extrémité à la structure 2 au moyen d'une articulation 7 et, par son autre extrémité, au volet 1 au moyen d'une articulation 8.On at least one side of the
Comme on le voit mieux sur la Fig. 2, cette articulation 8 est portée par un premier levier 9 articulé en 19 sur une platine 10 fixée sur le bord latéral de l'encadrement 11 du volet 1. Une biellette 12 est reliée par une articulation 13 au premier levier 9 et par une articulation 14 à un second levier 15 lui-même relié par une articulation 16 à la platine 10.As best seen in Fig. 2, this
L'articulation 14 de la biellette 12 est située, sur le second levier 15, en un point intermédiaire entre l'articulation 16 et un galet 17 monté à l'extrémité du levier 15 opposée à l'articulation 16 de ce dernier sur la platine 10. Le galet 17, en position de fermeture du volet 1, coopére avec le fond de la gouttière 6 sur laquelle il s'appuie. De préférence, une plaquette de protection 18, par exemple en plastique souple, est interposée entre le galet 17 et le fond de la gouttière 6.The
Le fonctionnement du dispositif décrit ci-dessus est très simple :The operation of the device described above is very simple:
La force exercée par le ressort pneumatique 5 crée, sur le premier levier 9, un couple dirigé dans le sens de la flèche F. Ce couple provoque un effort sur la biellette 12 en direction du second levier 15 qui, prenant appui sur la structure 2 par son galet 17, tend à relever le volet 1. Ce mouvement de relevage est effectif dès la libération de la serrure 4. Lorsque le second levier 15 est complètement déployé (Fig. 3), le bras de levier de la ligne d'action du ressort 5 par rapport à l'articulation 3 du volet 1 est alors suffisamment grand pour que le ressort 5 exerce, sur le volet 1, un couple de relevage notable.The force exerted by the
Cependant, de préférence, on s'arrange pour qu'un effort manuel réduit soit nécessaire après une faible course d'ouverture du volet 1, avant de poursuivre l'automatisme, ce qui évite l'inconvénient d'une ouverture incontrôlée qui pourrait être trop brutale.However, preferably, it is arranged that a reduced manual effort is necessary after a short opening stroke of the
Sur le diagramme de la Fig. 5, la courbe A représente, en fonction de son angle d'ouverture "a", le couple effectif sur le volet 1, résultant de la différence entre le couple dû à l'assistance et le couple dû à son poids, si l'articulation 8 du ressort 5 était portée directement par le volet. On voit que le couple C, donc l'effort demandé à l'utilisateur, pour décoller le volet 1 est relativement important, le couple d'assistance ne devenant prépondérant, pour assurer l'automatisme, que dans la deuxième moitié de l'ouverture (à partir de l'angle a1).In the diagram of Fig. 5, curve A represents, as a function of its opening angle "a", the effective torque on the
La courbe B représente, dans les mêmes conditions, le couple effectif sur le volet 1 grâce au dispositif selon l'invention. L'effet d'assistance est alors prépondérant dès le début, ce qui assure un soulèvement automatique du volet jusqu'à l'angle a2. Il faut alors exercer un couple réduit, égal au maximum à C', pour retrouver l'automatisme à partir de l'angle a1.Curve B represents, under the same conditions, the effective torque on the
Il convient de remarquer que le dispositif décrit pourrait éventuellement être disposé à l'autre extrémité du ressort 5, la platine 10 étant alors fixée sur la structure 2 et le galet 17 coopérant avec le volet 1. Toutefois, dans cette solution, l'action de relevage du volet due au déploiement du second levier 15 serait angulairement plus limitée.It should be noted that the device described could possibly be arranged at the other end of the
