Description

DISPOSITIF DE FIXATION, NOTAMMENT POUR PANNEAUX
DE GARNISSAGE
L'invention concerne un dispositif de fixation, notamment pour panneau de garnissage sur une paroi en tôle du type comportant un premier élément avec tête de retenue dans le panneau prolongé par une queue d'accrochage comprenant une zone d' encliquetage dans un second élément de retenue porté par la paroi de tale.FIXING DEVICE, PARTICULARLY FOR PANELS
TRIM
The invention relates to a fixing device, in particular for trim panel on a sheet metal wall of the type comprising a first element with retaining head in the panel extended by a hooking tail comprising a zone of snap-fastening in a second element of retaining carried by the wall of tale.

Un tel dispositif connu par la publication FR-A- 2 561 726 s'applique à la fixation de panneaux de garnissage sur une paroi de carrosserie de véhicule automobile.Such a device known from the publication FR-A-2 561 726 applies to the fixing of trim panels on a wall of a motor vehicle body.

Lors du positionnement du panneau dont la périphérie porte un ensemble d' éléments en vue de sa fixation sur la paroi en tale, les tolérances de fabrication du panneau et de montage sur celui-ci des éléments d' une part, la répartition des éléments de retenue d' autre part ne permettent pas tou!ours de réaliser de manière satisfaisante la fixation projetée. Ce problème peut être aggravé par les déformations locales du panneau de garnissage et/ou des éléments du dispositif.When positioning the panel, the periphery of which carries a set of elements with a view to fixing it to the sheet wall, the manufacturing tolerances of the panel and the mounting of the elements thereon on the one hand, the distribution of the elements of restrained on the other hand do not always allow to perform satisfactorily the projected fastening. This problem can be aggravated by local deformations of the trim panel and / or the elements of the device.

L'invention a pour objet d'apporter une solution au problème posé. Par conséquent, I' un des objets de l'invention est de proposer un dispositif à élément de fixation perfectionné fabriqué en une matière pDlymère qui soit d' une structure unitaire pour montage sur un élément de retenue susceptible d' occuper une position non coaxiale par rapport au premier élément.The object of the invention is to provide a solution to the problem posed. Consequently, one of the objects of the invention is to provide a device with an improved fastening element made of a polymer material which is of a unitary structure for mounting on a retaining element capable of occupying a non-coaxial position by compared to the first element.

Selon l'invention, le problème est résolu par le fait que la tête de retenue est reliée à la queue d' accrochage par une liaison souple disposée à la périphérie d'un bloc transmetteur de l'effort de montage qui fait corps avec ladite tête de retenue et qui est séparé axialement d' une base d' appui portant lesdites queue d'accrochage et liaison.According to the invention, the problem is solved by the fact that the retaining head is connected to the latching tail by a flexible link disposed at the periphery of a transmitter block of the mounting force which is integral with said head retaining and which is axially separated from a support base carrying said hooking tail and link.

Le dispositif ainsi réalisé permet l'application sur le premier élément d' un effort de montage et de pression axial au cours duquel le bloc entre en contact avec la base par suite de la déformation de la liaison souple. The device thus produced allows the application on the first element of a mounting force and axial pressure during which the block comes into contact with the base as a result of the deformation of the flexible connection.

Il en résulte que 1' effort de montage axial est transmis intégralement la queue d' accrochage sans engendrer de moments fléchissants susceptibles de déformer 1' élément de fixation.As a result, the axial mounting force is transmitted in full to the hooking tail without generating bending moments liable to deform the fastening element.

Un autre avantage du dispositif réside dans le fait que la queue d' accrochage et 1' élément de retenue séparés selon l'invention du panneau et du bloc transmetteur d'effort forment une liaison sans contact susceptible d'inclure un amortisseur de vibration.Another advantage of the device lies in the fact that the hooking tail and the separate retaining element according to the invention from the panel and from the force transmitter block form a contactless connection capable of including a vibration damper.

Un autre avantage du dispositif réside dans le fait que cleuici ne peut être détruit au cours du montage du panneau et peut être séparé de I' élément de retenue lorsque la liaison souple est soumise à un effort de traction.Another advantage of the device lies in the fact that it cannot be destroyed during assembly of the panel and can be separated from the retaining element when the flexible connection is subjected to a tensile force.

II en résulte que l'ensemble des éléments de fixation peuvent être placés préalablement dans le moule de confection du panneau dans le but de faciliter la fabrication d' un panneau prêt à poser qui ne présente aucun risque de détérioration des éléments de fixation. As a result, all of the fastening elements can be placed beforehand in the panel-making mold in order to facilitate the manufacture of a ready-to-install panel which presents no risk of deterioration of the fastening elements.

D' autres caractéristiques et avantages du dispositif apparattront à la lecture de la description d'un mode de réalisation de celui-ci en référence au dessin annexe sur lequel - la figure 1 est une représentation schématique d' un panneau de
garnissage monté sur une paroi intérieure de porte de véhicule, - la figure 2 est une coupe partielle du panneau selon la ligne 2-2 de la
figure 1, - la figure 3 est une représentation à une plus grande échelle de
I' ensemble de la fixation, - la figure 4 est une section du dispositif selon la ligne 4-4 de la figure
3. Other characteristics and advantages of the device will appear on reading the description of an embodiment of it with reference to the accompanying drawing in which - Figure 1 is a schematic representation of a panel
lining mounted on an interior wall of a vehicle door, - Figure 2 is a partial section of the panel along line 2-2 of the
Figure 1, - Figure 3 is a representation on a larger scale of
I 'the whole fixing, - Figure 4 is a section of the device according to line 4-4 of the figure
3.

La figure 1 représente une porte latérale de véhicule automobile dont la paroi intérieure 1 porte le panneau de garnissage 2.FIG. 1 represents a side door of a motor vehicle, the inner wall 1 of which carries the trim panel 2.

Le panneau de garnissage porte un ensemble de dispositifs de fixation 3 dont chacun possède un premier élément à tête 4 de retenue. Selon un mode de réalisation du panneau 2, l'ensemble des dispositifs 3 est préalablement disposé dans le moule de fabrication du panneau de sorte que les têtes 4 soient noyées dans la matière constitutive du panneau.The trim panel carries a set of fixing devices 3, each of which has a first head element 4 for retaining. According to one embodiment of the panel 2, all of the devices 3 are previously disposed in the panel manufacturing mold so that the heads 4 are embedded in the material constituting the panel.

La tête 4 se prolonge axialement par une queue 5 d' accrochage terminée par un bourrelet 6 adjacent à une gorge d' encliquetage 7 coopérant avec des éléments internes d' accrochage 8 disposés sur le bord d'une ouverture d'introduction située sur un élément 10 de retenue étanche réalisé en une matière relativement élastique qui ne fait pas partie de la présente invention et qui est porté par la paroi 1.The head 4 is extended axially by a hooking tail 5 terminated by a bead 6 adjacent to a latching groove 7 cooperating with internal hooking elements 8 disposed on the edge of an introduction opening located on an element 10 of tight retaining made of a relatively elastic material which is not part of the present invention and which is carried by the wall 1.

Selon l'invention, la tête 4 est reliée à la queue 5 d' accrochage par une liaison souple constituée par une cage à barreaux 11 flexibles disposés à la périphérie d'un bloc 12 transmetteur de l'effort F de montage. Le bloc 12 qui fait corps avec la tête 4 est séparé axialement d'une base 13 d'appui dont les faces opposées portent respectivement la queue 5 et les barreaux 11. Les barreaux il dont les extrémités sont respectivement fixées à la tête 4 et à la base 13 permettent lors de leur flexion sous I'action de l'effort F, la mise en contact du bloc 12 avec la base 13 et l'introduction de la queue 5 dans l'élément de retenue 10 notamment lorsque les axes respectifs de 1' éléments 10 et de la tête 4 sont décalés latéralement comme cela est représenté à la figure 2.According to the invention, the head 4 is connected to the tail 5 for attachment by a flexible connection constituted by a cage with flexible bars 11 arranged at the periphery of a block 12 transmitting the mounting force F. The block 12 which is integral with the head 4 is axially separated from a support base 13 whose opposite faces carry respectively the tail 5 and the bars 11. The bars 11 whose ends are respectively fixed to the head 4 and to the base 13 allow during their bending under the action of the force F, the contacting of the block 12 with the base 13 and the introduction of the tail 5 in the retaining element 10 in particular when the respective axes of The elements 10 and of the head 4 are offset laterally as shown in FIG. 2.

Par contre, au cours de la séparation des éléments du dispositif, les barreaux 11 supportent la totalité de l'effort de traction sans préludice pour le dispositif. On the other hand, during the separation of the elements of the device, the bars 11 support the entire tensile force without prelude to the device.

Dans le but de limiter les contacts accidentels entre le bloc 12 et la base 13 à la suite de la réalisation de la fixation, il peut être souhaitable de placer dans la cage à barreaux 11 un bloc 14 de mousse compressible amortisseur de chocs dont la présence supprime la transmission des vibrations de la paroi 1 au panneau 2 et participe par voie de conséquence à l'insonorisation du véhicule. In order to limit accidental contact between the block 12 and the base 13 following the completion of the attachment, it may be desirable to place in the bar cage 11 a block 14 of compressible shock absorbing foam whose presence eliminates the transmission of vibrations from the wall 1 to the panel 2 and consequently participates in the soundproofing of the vehicle.
