Description

FIXATION FUSIBLE D'UN ORGANE DE MOTORISATION DE LEVE-VITRE SUR UNE DOUBLURE DE PORTE FUSING A MOTORIZATION MEMBER OF A WINDOW LIFTER ON A DOOR LINING

La présente invention se rapporte à un ensemble pour portière de véhicule 5 automobile comprenant un organe de motorisation pour un dispositif de lève-vitre et une doublure de porte. Il existe sur plusieurs types de dispositifs de lève-vitre. Un des plus fréquemment utilisé comporte un rail de guidage unique implanté à l'intérieur d'un caisson de portière, délimité entre une peau de portière et une doublure de porte. Ce rail de guidage unique est destiné à 10 guider le déplacement d'une vitre de portière, tandis que le déplacement de la vitre sur le rail de guidage est assuré par un organe de motorisation. Un dispositif de lève-vitre comprend ainsi un rail de guidage, un organe de motorisation et une vitre. Généralement, l'organe de motorisation est fixé d'une part au rail de guidage unique et, d'autre part, à la doublure de porte. La fixation de l'organe de motorisation à la doublure de porte permet en particulier d'éviter des mouvements de 15 rotation intempestifs de l'organe de motorisation autour du rail de guidage et d'éviter des nuisances sonores à l'intérieur de l'habitacle du véhicule équipé d'un tel dispositif. Pour vérifier que les véhicules respectent les contraintes de sécurités et pour obtenir une homologation par les autorités, les constructeurs d'automobiles doivent soumettre leurs véhicules à des essais de choc, en particulier, à des chocs latéraux dont les conditions 20 sont bien définies. Ainsi, lors d'un choc latéral, les déformations subies par une portière ne doivent pas engendrer la rupture d'un panneau de garnissage recouvrant la doublure de portière du côté de l'habitacle du véhicule. L'organe de motorisation représente un des éléments les plus susceptibles de perforer le panneau de garnissage lors d'un choc latéral, en particulier en raison de sa masse. En effet, lors d'un choc latéral, l'organe de motorisation se déplace en suivant la 25 déformation du rail de guidage sur lequel il est fixé. Les fixations de l'organe de motorisation entrainent généralement un mouvement de rotation qui amplifie les déplacements de l'organe de motorisation et favorise ainsi son intrusion dans l'habitacle en perforant la doublure de porte. La présente invention a pour objet de remédier en tout ou partie aux différents inconvénients cités précédemment. Dans ce contexte technique, la présente invention a pour 30 objet de fournir un ensemble comportant un organe de motorisation et une doublure de porte qui évite la perforation du panneau de garnissage par l'organe de motorisation. A cet effet, la présente invention se rapporte à un ensemble pour portière de véhicule automobile comprenant un organe de motorisation pour un dispositif de lève-vitre et une doublure de porte, l'ensemble comprenant en outre des moyens de fixation conçus pour fixer 35 l'organe de motorisation sur la doublure de porte, l'ensemble étant caractérisé en ce que les moyens de fixation comportent une zone de moindre résistance et/ou une fente pour permettre de désolidariser l'organe de motorisation et la doublure de porte sous l'effet d'un effort seuil prédéterminé transmis à l'ensemble, notamment en cas de choc. Ainsi, un ensemble selon l'invention permet d'éviter la perforation du panneau de garnissage par l'organe de motorisation lors d'un choc : en effet, sous l'effet d'un effort seuil prédéterminé transmis à l'ensemble, la zone de moindre résistance et/ou la fente permettent de désolidariser l'organe de motorisation et la doublure de porte qui se déforment de façons indépendantes. La doublure de porte désolidarisée de l'organe de motorisation n'induit en particulier plus de mouvement de rotation de ce dernier, ce qui permet de minimiser ses déplacements. Une zone de moindre résistance ou une fente sont simples à réaliser et n'impliquent pas de modifications importantes par rapport à une doublure de porte et/ou un organe de motorisation classiques. Enfin, l'ensemble selon l'invention permet d'obtenir l'effet recherché sans ajout de masse dans la portière et ne représente pas un impact économique. Dans un mode de réalisation de l'invention, la zone de moindre résistance est 15 conçue pour se rompre sous l'effet de l'effort seuil prédéterminé. Dans un mode de réalisation de l'invention, l'ensemble comporte en outre des moyens de fixation complémentaires pour permettre la fixation de l'organe de motorisation sur un rail de guidage du dispositif de lève-vitre, et conçus pour que l'organe de motorisation reste solidaire du rail de guidage sous l'effet de l'effort seuil prédéterminé. 20 Selon une possibilité de l'invention, les moyens de fixation comportent un orifice et une vis adaptée pour coopérer avec ledit orifice et assurer la fixation de l'organe de motorisation sur la doublure de porte, l'orifice étant ménagé dans l'un des éléments choisis parmi l'organe de motorisation ou la doublure de porte, la vis étant solidaire de l'autre élément. La réalisation des moyens de fixation à l'aide d'une vis et d'un orifice adapté est simple. 25 Selon une caractéristique, la zone de moindre résistance comporte au moins une partie de la vis. Ainsi, la vis peut être une vis conçue pour se rompre sous l'effet d'un effort de cisaillement. Une telle vis peut être en particulier réalisée en matière plastique. Dans un mode de réalisation de l'invention, la zone de moindre résistance comprend au moins une partie du pourtour dudit orifice. Ainsi, en se rompant, la zone de 30 moindre résistance augmente les dimensions de l'orifice pour que la vis ne puisse plus coopérer avec l'orifice et pour permettre la désolidarisation de l'organe de motorisation et de la doublure de porte. Selon une caractéristique, les moyens de fixation comportent une fente prolongeant l'orifice et débouchant sur un bord de l'élément dans lequel l'orifice est ménagé. 35 Une telle fente permet de guider la vis des moyens de fixation vers le bord de l'élément dans lequel l'orifice est ménagé pour désolidariser l'organe de motorisation et la doublure de porte. The present invention relates to an automobile vehicle door assembly comprising a drive member for a window regulator device and a door liner. It exists on several types of window regulators. One of the most frequently used includes a single guide rail located inside a door box, delimited between a door skin and a door liner. This single guide rail is intended to guide the movement of a door window, while the movement of the window on the guide rail is provided by a drive member. A window lifter device thus comprises a guide rail, a drive member and a window. Generally, the motor member is fixed firstly to the single guide rail and, secondly, to the door liner. The attachment of the actuator member to the door liner in particular makes it possible to avoid inadvertent rotation movements of the motorization member around the guide rail and to avoid noise disturbances inside the door liner. cabin of the vehicle equipped with such a device. In order to verify that the vehicles comply with safety constraints and to obtain approval by the authorities, automobile manufacturers must submit their vehicles to impact tests, in particular to side impacts whose conditions are well defined. Thus, during a side impact, the deformations experienced by a door must not cause the rupture of a trim panel covering the door liner on the side of the passenger compartment of the vehicle. The drive member is one of the elements most likely to perforate the trim panel during a side impact, especially because of its mass. Indeed, during a side impact, the motorization member moves following the deformation of the guide rail on which it is fixed. The fasteners of the actuator member generally cause a rotational movement which amplifies the movements of the actuator member and thus promotes its intrusion into the passenger compartment by perforating the door liner. The present invention aims to remedy all or part of the various disadvantages mentioned above. In this technical context, it is an object of the present invention to provide an assembly comprising a drive member and a door liner which prevents perforation of the trim panel by the drive member. To this end, the present invention relates to an assembly for a motor vehicle door comprising an actuator member for a window lifter device and a door liner, the assembly further comprising fastening means designed to secure the door. motorization member on the door liner, the assembly being characterized in that the fastening means comprise a zone of least resistance and / or a slot to allow the actuator member and the door liner to be separated from each other. effect of a predetermined threshold force transmitted to the assembly, especially in case of shock. Thus, an assembly according to the invention makes it possible to prevent the perforation of the lining panel by the actuator member during an impact: indeed, under the effect of a predetermined threshold force transmitted to the assembly, the zone of least resistance and / or the slot make it possible to separate the actuating member and the door lining which deform in independent ways. The door liner disengaged from the actuator member induces in particular more rotational movement of the latter, which allows to minimize its movements. A zone of least resistance or a slot are simple to implement and do not involve significant changes compared to a door liner and / or a conventional actuator. Finally, the assembly according to the invention makes it possible to obtain the desired effect without adding mass to the door and does not represent an economic impact. In one embodiment of the invention, the zone of least resistance is designed to break under the effect of the predetermined threshold force. In one embodiment of the invention, the assembly further comprises complementary fastening means to allow the attachment of the actuator member on a guide rail of the window lifter device, and designed so that the body motor remains secured to the guide rail under the effect of the predetermined threshold force. According to a possibility of the invention, the fastening means comprise an orifice and a screw adapted to cooperate with said orifice and ensure the attachment of the actuator member to the door liner, the orifice being formed in one elements selected from the motorization member or the door liner, the screw being secured to the other element. The realization of the fastening means with a screw and a suitable orifice is simple. According to one characteristic, the zone of least resistance comprises at least part of the screw. Thus, the screw may be a screw designed to break under the effect of a shearing force. Such a screw may in particular be made of plastic. In one embodiment of the invention, the zone of least resistance comprises at least a portion of the periphery of said orifice. Thus, in breaking, the area of least resistance increases the dimensions of the orifice so that the screw can no longer cooperate with the orifice and to allow the separation of the drive member and the door liner. According to one feature, the fastening means comprise a slot extending the orifice and opening on an edge of the element in which the orifice is formed. Such a slot makes it possible to guide the screw of the fastening means towards the edge of the element in which the orifice is arranged so as to separate the actuator member and the door liner.

Selon une possibilité, la fente forme un coude. Un tel coude permet d'éviter la désolidarisation intempestive de l'organe de motorisation et de la doublure de porte à la suite de vibrations mais en l'absence de choc. La présente invention concerne également une portière de véhicule automobile comportant un ensemble selon l'invention. L'invention sera bien comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé, représentant à titre d'exemples non limitatifs plusieurs formes de réalisation d'un ensemble selon l'invention, dans lequel : La figure 1 est une vue d'ensemble d'une portière selon l'invention ; La figure 2 est une vue en perspective partielle d'une première forme de réalisation d'une portière selon l'invention ; la figure 3 est une vue semblable à la figure 2 présentant une deuxième forme de réalisation d'une portière. Une portière 1 selon l'invention, représentée sur la figure 1, comporte un rail de guidage 2 unique pour une vitre, non représentée, et un organe de motorisation 3 permettant le déplacement de la vitre sur le rail de guidage 2. Un dispositif de lève-vitre comprend ainsi le rail de guidage 2, l'organe de motorisation 3 et la vitre. Le rail de guidage 2 et l'organe de motorisation 3 sont disposés dans un caisson de portière 4 prévu à cet effet et délimité entre une peau de portière 5 et une doublure de porte 6 (représentée partiellement sur la figure 1). According to one possibility, the slot forms an elbow. Such elbow makes it possible to avoid inadvertent disconnection of the actuator member and the door liner as a result of vibrations but in the absence of shock. The present invention also relates to a motor vehicle door comprising an assembly according to the invention. The invention will be better understood with the aid of the detailed description which is explained below with reference to the appended drawing, representing by way of nonlimiting examples several embodiments of an assembly according to the invention, in which: Figure 1 is an overview of a door according to the invention; Figure 2 is a partial perspective view of a first embodiment of a door according to the invention; Figure 3 is a view similar to Figure 2 showing a second embodiment of a door. A door 1 according to the invention, shown in Figure 1, comprises a single guide rail 2 for a window, not shown, and a motor member 3 for moving the window on the guide rail 2. A device for The window regulator thus comprises the guide rail 2, the motorization member 3 and the window. The guide rail 2 and the drive member 3 are arranged in a door box 4 provided for this purpose and delimited between a door skin 5 and a door liner 6 (shown partially in Figure 1).

L'ensemble 7 selon l'invention comporte l'organe de motorisation 3, la doublure de porte 6 et des moyens de fixation de l'organe de motorisation 3 sur la doublure de porte 6. L'ensemble 7 comporte en outre des moyens de fixation complémentaires pour permettre la fixation de l'organe de motorisation 3 sur le rail de guidage 2 de manière à ce que l'organe de motorisation 3 et le rail de guidage 2 restent solidaires lors de déformations engendrées par un choc latéral. The assembly 7 according to the invention comprises the actuator member 3, the door liner 6 and means for fastening the actuator member 3 to the door liner 6. The assembly 7 further comprises means for complementary fixing to allow the attachment of the actuator member 3 on the guide rail 2 so that the motor member 3 and the guide rail 2 remain integral during deformations generated by a side impact.

De tels moyens de fixation complémentaires peuvent être réalisés simplement sous la forme de rivets 8 représentés sur les figures 1 à 3. Les moyens de fixation comportent, par exemple, un orifice 9 et une vis 10 adaptée pour coopérer avec ledit orifice 9 et assurer la fixation de l'organe de motorisation 3 sur la doublure de porte 6. L'orifice 9 peut être indifféremment ménagé dans un des éléments que sont l'organe de motorisation 3 ou la doublure de porte 6, la vis 10 étant alors solidaire de l'autre élément. Dans les exemples illustrés aux figures 1 à 3, l'orifice 9 est disposé sur la doublure de porte 6 et la vis est fixée à l'organe de motorisation 3. L'invention n'est cependant pas limitée à cette forme de réalisation et, en particulier, l'orifice 9 pourrait être disposé sur l'organe de motorisation 3 et la vis 10 sur la doublure de porte 6. Such complementary fastening means can be made simply in the form of rivets 8 shown in FIGS. 1 to 3. The fastening means comprise, for example, an orifice 9 and a screw 10 adapted to cooperate with said orifice 9 and provide the fixing the actuator member 3 on the door liner 6. The orifice 9 may be indifferently formed in one of the elements that are the actuator member 3 or the door liner 6, the screw 10 then being secured to the other element. In the examples illustrated in FIGS. 1 to 3, the orifice 9 is disposed on the door liner 6 and the screw is fixed to the actuator member 3. The invention is however not limited to this embodiment and in particular, the orifice 9 could be arranged on the motorization member 3 and the screw 10 on the door liner 6.

Dans une première forme de réalisation de l'invention, illustrée à la figure 2, les moyens de fixation de l'ensemble 7 comportent une zone de moindre résistance 11 conçue pour se rompre sous l'effet d'un effort seuil prédéterminé transmis à l'ensemble 7 lors d'un choc latéral. Cette zone de moindre résistance 11 est, par exemple, située sur la doublure de porte 6 et comporte une partie du pourtour de l'orifice 11 de sorte que, lors d'un choc latéral, l'ensemble 7 subissant un effort supérieur ou égal à l'effort seuil prédéterminé, la zone de moindre résistance 11 se rompe pour augmenter les dimensions de l'orifice 9 afin que la vis 10 puisse se dégager de cet orifice 9. Lors de la déformation de la portière 1 durant un choc latéral, après rupture de la zone de moindre résistance 11, l'organe de motorisation 3 et la doublure de porte 6 se déforment de manières indépendantes, la vis 10 se dégageant de l'orifice 9. La zone de moindre résistance 11 peut également se situer sur la vis 10 afin d'entrainer, lorsque l'ensemble 7 est soumis à un choc latéral, la rupture de la vis 10. Une vis 10 réalisée dans un matériau plastique convient particulièrement bien pour réaliser une telle zone de moindre résistance 11. In a first embodiment of the invention, illustrated in FIG. 2, the fastening means of the assembly 7 comprise a zone of least resistance 11 designed to break under the effect of a predetermined threshold force transmitted to the 7 together during a side impact. This zone of least resistance 11 is, for example, located on the door liner 6 and comprises a portion of the periphery of the orifice 11 so that, during a lateral impact, the assembly 7 undergoing a greater or equal effort at the predetermined threshold force, the zone of least resistance 11 breaks to increase the dimensions of the orifice 9 so that the screw 10 can be released from this orifice 9. During the deformation of the door 1 during a side impact, after rupture of the zone of least resistance 11, the motorization member 3 and the door liner 6 deform independently, the screw 10 emerging from the orifice 9. The zone of least resistance 11 can also be located on the screw 10 to drive, when the assembly 7 is subjected to a side impact, the rupture of the screw 10. A screw 10 made of a plastic material is particularly suitable for producing such a zone of least resistance 11.

Evidement, la zone de moindre résistance 11 peut englober à la fois une partie de la vis 10 et une partie du pourtour de l'orifice 9. Dans une deuxième forme de réalisation de l'invention, illustrée à la figure 3, les moyens de fixation de l'ensemble 7 comportent, outre la vis 10 et l'orifice 9, une fente 12 prolongeant l'orifice 9 et permettant à la vis 10 de glisser et de se désolidariser de la doublure de porte 6 durant la déformation de l'ensemble 7 soumis à un effort seuil prédéterminé. En particulier, la fente 12 est, par exemple, une fente qui débouche sur un bord 13 de l'élément comportant l'orifice 9, c'est-à-dire sur la doublure de porte 6 dans l'exemple illustré à la figure 3. Cette fente 12 forme par exemple un coude. Ainsi, durant la déformation due à un choc latéral, la vis 10 est guidée vers le bord de la doublure de porte 6 pour désolidariser la doublure de porte 6 et l'organe de motorisation 3. Dans un mode de réalisation non illustré, outre la fente 12, la doublure de porte 6 peut également comporter une zone de moindre résistance 11 comportant une partie du pourtour de l'orifice 9 et de la fente 12. Ainsi, l'ensemble selon l'invention décrit ci-dessus permet d'éviter la perforation de 30 la doublure de porte 6 par l'organe de motorisation 3 lors d'un choc. Bien entendu, les exemples de réalisations évoqués ci-dessus ne présentent aucun caractère limitatif et d'autres détails et améliorations peuvent être apportés à un ensemble selon l'invention, sans pour autant sortir du cadre de l'invention où d'autres formes de l'ensemble peuvent être réalisées. Of course, the zone of weakness 11 may encompass both a portion of the screw 10 and a portion of the periphery of the orifice 9. In a second embodiment of the invention, illustrated in FIG. fixing the assembly 7 comprise, in addition to the screw 10 and the orifice 9, a slot 12 extending the orifice 9 and allowing the screw 10 to slide and to separate from the door liner 6 during the deformation of the set 7 subjected to a predetermined threshold effort. In particular, the slot 12 is, for example, a slot which opens on an edge 13 of the element having the orifice 9, that is to say on the door liner 6 in the example shown in FIG. 3. This slot 12 forms for example a bend. Thus, during the deformation due to a side impact, the screw 10 is guided towards the edge of the door liner 6 to separate the door liner 6 and the actuator member 3. In a non-illustrated embodiment, in addition to the slot 12, the door liner 6 may also include a zone of weakness 11 having a portion of the periphery of the orifice 9 and the slot 12. Thus, the assembly according to the invention described above makes it possible to avoid perforation of the door liner 6 by the actuator member 3 during an impact. Of course, the examples of embodiments mentioned above are not limiting and other details and improvements can be made to an assembly according to the invention, without departing from the scope of the invention where other forms of all can be realized.
