Description
La présente invention a pour objet un dispositif lève-vitre pour véhicule automobile, comprenant un motoréducteur d'entraînement d'une chaîne cinématique à l'extrémité de laquelle est montée la vitre.The present invention relates to a window lifter device for a motor vehicle, comprising a geared motor for driving a kinematic chain at the end of which the window is mounted.
Il est connu que généralement les lève-vitre sont équipés d'éléments souples ou flexibles en vue d'absorber l'énergie cinétique lors de l'arrivée du lève-vitre en butée, par exemple comme décrit dans le EP-A 008 247 (languettes élastiques 21, 22).It is known that generally the window regulators are fitted with flexible or flexible elements with a view to absorbing the kinetic energy when the window regulator arrives at the stop, for example as described in EP-A 008 247 (
Cependant, les caractéristiques de ces absorbeurs d'énergie ne permettent pas de transformer un choc dur en choc mou.However, the characteristics of these energy absorbers do not allow a hard shock to be transformed into a soft shock.
On sait en effet que certaines normes concernant les sécurités de lève-vitre automobile peuvent exiger un test avec un objet dur. Ce test consiste à mettre un objet dur dans la trajectoire de la vitre, et à déterminer si après contact de la vitre avec l'objet dur et descente de celle-ci, l'effort subi par l'objet n'a pas dépassé une certaine limite, par exemple 10 kg. Or, certains systèmes de sécurité peuvent subir des efforts nettement supérieurs lors de tests à l'aide d'objets durs. Ceci provient de la rigidité et de l'inertie du système de lève-vitre et de la vitre, inertie qui est fonction de la vitesse. Plus la vitesse de la vitre est grande, et plus grande est son inertie.We know that certain standards concerning the safety of car windows can require a test with a hard object. This test consists in putting a hard object in the trajectory of the glass, and in determining if after contact of the glass with the hard object and descent of the latter, the force undergone by the object has not exceeded a certain limit, for example 10 kg. However, some security systems can undergo significantly greater efforts during tests using hard objects. This is due to the rigidity and inertia of the window regulator system and the glass, which is a function of speed. The higher the speed of the window, the greater its inertia.
Théoriquement, un système complètement rigide que l'on arrête brusquement par un objet complètement rigide, développe sur ce dernier une force infinie. On comprend aisément que si le système déclenche sur un objet mou à une certaine valeur d'effort, il peut, si le test est effectué avec un objet rigide, dépasser largement cet effort. L'inertie même faible, si la vitesse de translation de la vitre est faible, peut engendrer des efforts très élevés.Theoretically, a completely rigid system that is abruptly stopped by a completely rigid object, develops on the latter an infinite force. It is easily understood that if the system triggers on a soft object at a certain force value, it can, if the test is carried out with a rigid object, greatly exceed this force. Even low inertia, if the speed of translation of the glass is low, can generate efforts very high.
Il peut donc s'avérer nécessaire dans certains cas de diminuer la rigidité du système et d'amortir le choc.It may therefore prove necessary in certain cases to reduce the rigidity of the system and to absorb the shock.
Le but de l'invention consiste précisément à résoudre ce problème d'une manière satisfaisante, résultat qui ne peut être atteint avec les éléments absorbeurs d'énergie cinétique mentionnés ci-dessus.The object of the invention is precisely to solve this problem in a satisfactory manner, a result which cannot be achieved with the kinetic energy absorbing elements mentioned above.
On connaît par ailleurs des documents décrivant des éléments élastiques dans la chaîne cinématique, adaptés à des fonctions spécifiques telles que fixation rapide (USA4706412, FR-2100148, USA 3281991), rattrapage de jeu (DE-2836032). Par ailleurs, le EP-A 0107531 divulgue un lève-vitre muni d'un ressort interrupteur de fin de course, incapable d'assurer une autre fonction que la détection d'efforts élevés de fin de course, donc de l'ordre de 25 à 30 kg, et ce à titre d'effet secondaire.We also know of documents describing elastic elements in the kinematic chain, adapted to specific functions such as quick fixing (USA4706412, FR-2100148, USA 3281991), backlash (DE-2836032). Furthermore, EP-A 0107531 discloses a window regulator provided with a limit switch spring, incapable of performing any function other than the detection of high end of stroke forces, therefore of the order of 25 at 30 kg, as a side effect.
Enfin, le GB-A822658 concerne un lève-vitre dans lequel un système élastique a pour fonction essentielle la commutation électrique entre des contacts électriques 19 et 20. En fin de course, ou en cas de rencontre d'obstacle, le ressort 35 ne doit réagir qu'à des efforts importants, soit environ 20 kg, afin de permettre, en utilisation normale, la rentrée de la vitre dans les joints à la fermeture. De ce fait, de par sa raideur trop élevée, un tel ressort ne peut assurer une fonction de transformation d'un choc dur en choc mou. De plus, si on veut substituer au ressort 35 un ressort capable d'assurer la transformation ci-dessus, un tel ressort sera dans l'incapacité de permettre la fermeture de la fenêtre par une entrée correcte de la vitre dans les joints. En effet, la commutation pour l'inversion du mouvement aura lieu trop tôt, du fait de la faiblesse du ressort.Finally, GB-A822658 relates to a window regulator in which an elastic system has the essential function of electrical switching between
Conformément à l'invention, la chaîne cinématique du dispositif lève-vitre comprend au moins un élément souple limiteur d'effort et amortisseur d'un choc dur de la vitre contre un obstacle dur placé sur sa trajectoire, cet élément souple étant adapté pour limiter l'effort à sensiblement 100 Newtons.In accordance with the invention, the kinematic chain of the window regulator device comprises at least one flexible force limiting element and shock absorber of a hard impact of the glass against a hard obstacle placed on its path, this flexible element being adapted to limit the force to substantially 100 Newtons.
Ce ou ces éléments de sécurité anti-pincement, au nombre par exemple de deux, convenablement positionnés, peuvent être constitués par des ressorts métalliques plats, ou bien par des blocs élastiques, notamment en caoutchouc ou autre matériau susceptible d'emmagasiner de l'énergie de déplacement et de la restituer.This or these anti-pinch safety elements, for example two in number, suitably positioned, may consist of flat metal springs, or else of elastic blocks, in particular of rubber or other material capable of storing energy. of displacement and to restore it.
Dans un lève-vitre du type comprenant un câble enroulé autour de poulies de renvoi et d'un tambour coopérant avec la sortie du motoréducteur, un rail de guidage du câble déplaçable en translation verticale par rapport à un panneau de porte, le câble portant un chariot support de la vitre, l'élément souple amortisseur peut être interposé entre le rail et le panneau de porte et fixé à ces derniers.In a window regulator of the type comprising a cable wound around deflection pulleys and a drum cooperating with the output of the gearmotor, a cable guide rail displaceable in vertical translation relative to a door panel, the cable carrying a glass support trolley, the flexible damping element can be interposed between the rail and the door panel and fixed to the latter.
Pour chaque type de lève-vitre, l'invention prévoit donc d'interposer un ou plusieurs éléments souples dans la chaîne cinématique afin d'amortir le choc de la vitre contre un obstacle dur, en constituant ainsi une sécurité anti-pincement évitant le choc dur.For each type of window regulator, the invention therefore provides for interposing one or more flexible elements in the kinematic chain in order to absorb the impact of the window against a hard obstacle, thereby constituting an anti-pinch safety device preventing the impact. hard.

La figure 14 est un graphique illustrant la transformation d'un choc dur en choc mou.FIG. 14 is a graph illustrating the transformation of a hard shock into a soft shock.
Le lève-vitre 1 représenté à la Fig.1 comprend un motoréducteur 2 d'entraînement d'un câble torsadé ou câble Bowden 3, passant sur 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, monté déplaçable en translation verticale par rapport à un panneau 7 de porte partiellement représenté.The
Le câble 3 porte un chariot 8 sur lequel est montée une vitre 9. Deux éléments souples amortisseurs 11 sont interposés entre le rail 6 de guidage et le panneau 7 et fixé à ceux-ci. Dans l'exemple représenté, chaque élément 11 est constitué par un ressort métallique plat ayant une configuration recourbée appropriée, dont une extrémité est fixée par tout moyen connu approprié par exemple des rivets, à un organe de liaison avec le rail 6, telle qu'une patte 12. Son extrémité opposée est fixée, de manière appropriée et également connue en soi, au panneau de porte 7.The
Ainsi un choc de la vitre 9 contre un obstacle placé sur sa trajectoire est transmis au chariot 8, puis au rail 6 et à l'ensemble du lève-vitre 1, et amorti par les ressorts plats 11. Ces derniers subissent une flexion à laquelle correspond un déplacement des organes constitutifs du lève-vitre. Ce déplacement a été représenté uniquement pour les poulies 4 et 5 et le câble 3, qui viennent dans la position 4a, 5a, 3a représentée en traits mixtes, et reviennent ensuite à leur position initiale sous l'effet de l'élasticité des ressorts 11.Thus a shock of the
Le second mode de réalisation, représenté à la Fig.2, diffère de celui de la Fig.1 uniquement par le fait que les éléments amortisseurs sont constitués par des blocs 13 en matériau élastique, par exemple du caoutchouc ("silent-blocks"). Ces blocs 13 sont montés de manière appropriée, par exemple enfilés sur des fiches 14 portées par des pattes 15 fixées au rail 6, l'extrémité des fiches 14 opposée aux pattes 15 étant fixée au panneau de porte (non représenté).The second embodiment, shown in Fig.2, differs from that of Fig.1 only in that the damping elements are constituted by
Dans la forme de réalisation du lève-vitre 1 à câble torsadé 3 représenté à la Fig.4, l'élément amortisseur 16 est interposé entre le chariot 8 et un support 17 de la vitre 9. Cet élément amortisseur 16 est réalisé en tout matériau souple et élastique approprié tel que du caoutchouc.In the embodiment of the
Dans la variante de la Fig.5, l'élément amortisseur 18 est constitué par un ressort plat métallique similaire aux ressorts 11. Cet amortisseur 18 est fixé au chariot 8 par l'une 18a de ses deux branches, et à la vitre 9 par sa seconde branche 18b, par tout moyen approprié, connu en soi.In the variant of FIG. 5, the
Le lève-vitre 19 représenté aux Fig.6 à 9 est du type à câble crémaillère 21 coulissant dans une gaine 22 engrenant avec un pignon 23 de sortie du motoréducteur 2. Un chariot 24 pouvant coulisser le long d'un rail 25 sensiblement vertical de guidage, est fixé au câble 21 et porte la vitre 9. L'élément amortisseur 26 est ici un ressort plat métallique, similaire aux ressorts 11, fixé d'une part au chariot 24 et d'autre part à la vitre 9 par des moyens connus en soi.The
Dans la variante de la Fig.7, l'amortisseur est constitué par un bloc 27 en toute matière souple et élastique convenable, interposé entre le chariot 24 et la vitre 9.In the variant of FIG. 7, the damper consists of a
Suivant la forme de réalisation du lève-vitre 19 représenté à la Fig.8, le système amortisseur est constitué par deux ressorts plats 28, similaires aux ressorts 11. Comme ces derniers les ressorts 28 sont montés sur des pattes 12 fixées au rail 25 par l'une 28a de leurs branches, tandis que leur seconde branche 18b est fixée au panneau de porte (non représenté).According to the embodiment of the
Dans la variante de la Fig.9, le système amortisseur est constitué par deux blocs élastiques 29 semblables aux blocs 13 et montés de la même manière que ces derniers, entre le rail 25 et le panneau de porte.In the variant of FIG. 9, the damping system consists of two similar
Le lève-vitre 31 illustré aux Fig.10 et 11 est du type à bras 32 et secteur denté 33 solidaire du bras 32, l'ensemble étant monté oscillant autour d'un axe 34 porté par un plateau fixe 35. Le secteur denté 33 coopère avec le pignon 23 de sortie du motoréducteur 2. Le bras 32 est équipé de plusieurs éléments amortisseurs souples 36, au nombre de 4 dans l'exemple représenté, solidarisés avec le support (non représenté) de la vitre. Les amortisseurs 36 sont réalisés et montés de la même manière que les blocs amortisseurs 13 (Fig.2 et 3).The
Dans la variante de la Fig.11, les quatre amortisseurs 36 sont remplacés par 4 ressorts plats métalliques 37, fixés par l'une 37a de leurs branches au bras 32, et par l'autre branche 38a au support (non représenté) de la vitre.In the variant of FIG. 11, the four
Le lève-vitre 39 illustré aux Fig.12 et 13 est du type à bras 41 solidaire d'un secteur denté 42 par l'une de ses extrémités, monté oscillant autour d'un axe 43 et dont l'extrémité opposée 41a porte la vitre 9. Un amortisseur 44 constitué par un ressort plat semblable à ceux des autres réalisations représentées, est interposé entre l'extrémité 41a et la vitre 9, et fixé à celles-ci par tout moyen adéquat.The
Dans la variante de la Fig.13, le ressort plat 44 est remplacé par un bloc souple 45 interposé entre un socle 46 solidaire de l'extrémité 41a du bras 41, et un support 47 de la vitre 9.In the variant of FIG. 13, the
La Fig. 14 montre la variation, lors d'un choc en fonction du temps t, de la force F transmise par l'obstacle. Dans le cas d'un choc dur, la courbe C1 est un pic extrêmement étroit, de l'ordre de la milliseconde, et dont l'amplitude A peut atteindre des valeurs énormes, incontrôlables.Fig. 14 shows the variation, during an impact as a function of time t, of the force F transmitted by the obstacle. In the case of a hard shock, the curve C1 is an extremely narrow peak, of the order of a millisecond, and of which amplitude A can reach enormous, uncontrollable values.
Dans le cas d'un choc mou, la courbe C2 voit la force rapidement limitée à une valeur B faible par rapport à A, en raison de son étalement dans le temps t, par exemple sur 10 millisecondes.In the case of a soft shock, the curve C2 sees the force quickly limited to a low value B compared to A, due to its spreading over time t, for example over 10 milliseconds.
L'invention est susceptible de diverses variantes d'exécution, tant en ce qui concerne le nombre des éléments amortisseurs que leur configuration géométrique. Il est notamment évident que les ressorts plats peuvent présenter une géométrie très variable, celle représentée n'étant fournie qu'à titre d'exemple. De même tout autre type de ressort peut convenir si son encombrement l'autorise, par exemple un ressort hélicoïdal.The invention is susceptible of various variants, both with regard to the number of damping elements and their geometric configuration. It is in particular obvious that the flat springs can have a very variable geometry, that shown only being provided by way of example. Similarly, any other type of spring may be suitable if its size allows it, for example a helical spring.
