DISPOSITIF DE RETENUE D'UNE GARNITURE D'HABILLAGE SUR UN CAISSON DE VOLET ARRIERE DE VEHICULE AUTOMOBILE. DEVICE FOR RETAINING A TRIM TRIM ON A REAR SHUTTER CASE OF A MOTOR VEHICLE.
Domaine technique Technical area
La présente invention revendique la priorité de la demande française 1873006 déposée le 17 décembre 2018 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims priority from French application 1873006 filed on December 17, 2018 whose content (text, drawings and claims) is here incorporated by reference.
La présente invention concerne d'une manière générale les volets arrière de véhicules automobiles. The present invention relates generally to the rear flaps of motor vehicles.
Elle concerne en particulier un dispositif de fixation d'une garniture d'habillage sur un caisson d'un tel volet arrière. It relates in particular to a device for fixing a covering trim to a box of such a rear flap.
Technique antérieure Prior art
Les volets arrière de véhicules automobiles, également dénommés hayons, comportent généralement une peau extérieure en tôle métallique et une doublure intérieure en tôle métallique assemblées l'une à l'autre pour former un caisson creux présentant une section transversale fermée afin d'assurer leur rigidité. The rear flaps of motor vehicles, also known as tailgates, generally comprise an outer skin of metal sheet and an inner lining of metal sheet joined together to form a hollow box having a closed cross section to ensure their rigidity. .
La partie supérieure d'un tel volet arrière comporte généralement une ouverture recouverte par une lunette arrière dont la périphérie est rapportée par collage sur un bandeau prévu sur la peau extérieure en retrait de cette ouverture. The upper part of such a rear flap generally has an opening covered by a rear window, the periphery of which is attached by bonding to a strip provided on the outer skin set back from this opening.
Les volets arrière comportent en outre un faisceau électrique destiné à être connecté à des équipements électriques situés dans différentes zones du volet. Ces composants électriques comprennent le plus souvent un troisième feu stop, des lampes d'éclairage de la plaque d'immatriculation, le moteur d'essuie-glace arrière et l'actionneur électrique de la serrure. The rear shutters also include an electrical harness intended to be connected to electrical equipment located in different areas of the shutter. These electrical components most often include a third brake light, license plate lights, the rear wiper motor and the electric actuator for the lock.
Afin de dissimuler et de protéger ces éléments techniques, chaque volet arrière comprend des garnitures d'habillage en matière plastique rapportées en fin d'assemblage sur le caisson métallique et venant en affleurement par l'un de leurs bords contre la lunette arrière. Ces garnitures d'habillage comportent habituellement une garniture inférieure recouvrant la partie du caisson située en dessous de la lunette arrière, une garniture supérieure recouvrant la partie du caisson située au dessus de cette lunette arrière, et deux garnitures latérales gauche et droite recouvrant les parties de caisson bordant latéralement cette même lunette arrière. In order to conceal and protect these technical elements, each rear flap comprises trim linings in plastic material added at the end of assembly on the metal box and coming into flush with one of their edges against the rear window. These trim linings usually comprise a lower lining covering the part of the box located below the rear window, an upper lining covering the part of the box located above this rear window, and two left and right side linings covering the parts of box laterally bordering this same rear window.
Les garnitures sont généralement fixées par encliquetage sur le caisson du volet arrière par l'intermédiaire d'agrafes de retenue plastiques ou métalliques élastiquement déformables et clipsées sur le pourtour de l'ouverture. The linings are generally fixed by snap-fastening to the box of the rear flap by means of plastic or metallic retaining clips which are elastically deformable and clipped around the periphery of the opening.
Avec le temps et sous l'effet des fortes variations de température auxquelles elles sont soumises lors de périodes de fort ensoleillement, ces garnitures d'habillage ont tendance à se déformer, en particulier au niveau de leurs bords affleurant la lunette arrière où ces déformations sont les plus perceptibles et peuvent laisser apparaître certaines parties du faisceau électrique et/ou des équipements électriques du véhicule. Over time and under the effect of the large temperature variations to which they are subjected during periods of strong sunshine, these trim linings tend to deform, in particular at the level of their edges flush with the rear window where these deformations are the most noticeable and may reveal certain parts of the vehicle's wiring harness and / or electrical equipment.
Ces déformations génèrent ainsi une dégradation sensible de la qualité perçue par les usagers des jeux et des affleurements. These distortions thus generate a significant deterioration in the quality perceived by the users of the games and outcrops.
Il est connu de palier à ces inconvénients en réalisant ces garnitures d'habillage dans des matériaux plastiques présentant des coefficients de dilatation thermique plus faibles et/ou en ménageant des renforts visant à les rigidifier localement de sorte à limiter leur déformation. It is known to overcome these drawbacks by making these trim fittings in plastic materials having lower coefficients of thermal expansion and / or by providing reinforcements aimed at stiffening them locally so as to limit their deformation.
La mise en œuvre de ces solutions entraîne malheureusement une augmentation sensible des coûts de revient et/ou un alourdissement de ces pièces. The implementation of these solutions unfortunately leads to a significant increase in production costs and / or an increase in these parts.

As shown in Figure 5, the rear flap 1 has an outer skin 10 and an inner lining 20 formed from stamped sheets and cut and joined to each other so as to form a hollow box 30 having a closed cross section to ensure their rigidity.
La peau 10 est dite extérieure du fait qu'elle est au contact de l'air extérieur tandis que la doublure 20 est dite intérieure du fait qu'elle est comprise entre la peau extérieure 10 et l'intérieur de l'habitacle ou du coffre. Tel qu'illustré sur la figure 1, la peau extérieure 10 est pourvue d'un rebord périphérique 11 qui est replié de manière continue derrière le bord périphérique de la doublure intérieure 20, de façon à constituer le caisson 30. The skin 10 is said to be exterior because it is in contact with the outside air while the lining 20 is said to be interior because it is between the exterior skin 10 and the interior of the passenger compartment or the trunk. . As illustrated in FIG. 1, the outer skin 10 is provided with a peripheral rim 11 which is continuously folded behind the peripheral edge of the inner lining 20, so as to constitute the box 30.
La partie supérieure du volet arrière 1 présente une ouverture 40 formée par deux découpes de mêmes dimensions réalisées dans la peau extérieure 10 et la doublure intérieure 20, et dont les pourtours respectifs 12, 22 sont superposés et soudés l'un à l'autre (voir figure 5). The upper part of the rear flap 1 has an opening 40 formed by two cutouts of the same dimensions made in the outer skin 10 and the inner lining 20, and whose respective edges 12, 22 are superimposed and welded to each other ( see figure 5).
L'ouverture 40 est recouverte par une lunette arrière 50 en verre dont la périphérie est rapportée par collage sur un bandeau 13 prévu sur la peau extérieure 10 et visible sur cette figure 5 (la lunette 50 n'étant pas représentée sur la figure 5 mais uniquement sur la figure 1). The opening 40 is covered by a rear window 50 made of glass, the periphery of which is attached by bonding to a strip 13 provided on the outer skin 10 and visible in this figure 5 (the window 50 not being shown in Figure 5 but only in Figure 1).
Tel qu'illustré sur cette figure 5, ce bandeau 13 s'étend à l'arrière de l'ouverture 40 en étant relié à son pourtour 12, 22 par un encadrement 14 formé par la peau extérieure 10 et s'étendant sensiblement longitudinalement. As illustrated in this FIG. 5, this strip 13 extends at the rear of the opening 40 while being connected to its periphery 12, 22 by a frame 14 formed by the outer skin 10 and extending substantially longitudinally.
Le volet arrière 1 comporte en outre un faisceau électrique non représenté et destiné à être connecté à des équipements électriques (non visibles sur les figures) situés dans différentes zones de ce volet. The rear flap 1 also comprises an electrical harness, not shown and intended to be connected to electrical equipment (not visible in the figures) located in different zones of this flap.
Ces équipements électriques comprennent notamment le troisième feu stop, les lampes d'éclairage de la plaque d'immatriculation, le moteur d'essuie-glace arrière ainsi que l'actionneur électrique de la serrure de ce volet 1. This electrical equipment notably includes the third brake light, the license plate lighting lamps, the rear wiper motor as well as the electric actuator for the lock of this shutter 1.
Afin de dissimuler et de protéger ces éléments techniques, le volet arrière 1 comprend une pluralité de garnitures d'habillage 60, 70 et 80 en matière plastique rapportées par encliquetage sur le caisson 30 et visibles sur la figure 1. In order to conceal and protect these technical elements, the rear flap 1 comprises a plurality of trim fittings 60, 70 and 80 made of plastic material fitted by snap-fastening on the box 30 and visible in FIG. 1.
Plus précisément, ces garnitures d'habillage comprennent : More specifically, these trim covers include:
- une garniture inférieure 60 recouvrant la partie située en dessous de la lunette arrière 50 de la face externe de la doublure intérieure 20 (i.e. celle tournée vers l'intérieur de l'habitacle ou du coffre), ainsi que les portions inférieures du pourtour 12, 22 de l'ouverture 40 et de l'encadrement 14 jusqu'à venir en affleurement de la lunette 50 ; - une garniture supérieure 70 recouvrant les portions supérieures de ce pourtour 12, 22 et de cet encadrement 14 jusqu'à venir en affleurement de la lunette 50 ; et - A lower lining 60 covering the part located below the rear window 50 of the external face of the interior lining 20 (ie that facing inwards of the passenger compartment or the boot), as well as the lower portions of the periphery 12 , 22 of the opening 40 and of the frame 14 until it comes flush with the bezel 50; - An upper lining 70 covering the upper portions of this periphery 12, 22 and of this frame 14 until it comes flush with the bezel 50; and
- deux garnitures latérales 80 recouvrant les portions latérales de ce pourtour 12, 22 et de cet encadrement 14 jusqu'à venir en affleurement de la lunette 50. two lateral linings 80 covering the lateral portions of this periphery 12, 22 and of this frame 14 until they come out of the bezel 50.
En référence aux figures 2 et 5, chaque garniture latérale 80 comporte un corps 81 venu de moulage d'une seule pièce à partir d'un polymère thermoplastique éventuellement renforcé en fibres naturelles et/ou synthétiques. Referring to Figures 2 and 5, each side trim 80 comprises a body 81 molded in one piece from a thermoplastic polymer optionally reinforced with natural and / or synthetic fibers.
Ce corps 81 comprend une paroi principale 82 recouvrant une portion latérale de l'encadrement 14, ainsi qu'un rebord 83 recouvrant une portion latérale du pourtour 12, 22 de l'ouverture 40. This body 81 comprises a main wall 82 covering a lateral portion of the frame 14, as well as a flange 83 covering a lateral portion of the periphery 12, 22 of the opening 40.
S'étendant à l'opposé du rebord 83, le bord libre 84 de la paroi principale 82 est conformé pour venir en affleurement de la lunette arrière 50 de sorte à obtenir une qualité perçue optimale. Extending opposite the rim 83, the free edge 84 of the main wall 82 is shaped to come flush with the rear window 50 so as to obtain optimum perceived quality.
L'extrémité supérieure 81A du corps 81 de chaque garniture latérale 80 est emboîtée sur un tenon respectif (non visible sur les figures) ménagé à l'extrémité latérale correspondante de la garniture supérieure 60, en y étant fixée par l'intermédiaire de pattes déformables élastiquement s'étendant depuis la face interne de cette extrémité supérieure 81A (i.e. sa face tournée vers le caisson 30) et coopérant par encliquetage avec des fenêtres ménagées sur ce tenon. The upper end 81A of the body 81 of each side trim 80 is fitted onto a respective lug (not visible in the figures) formed at the corresponding lateral end of the upper trim 60, by being fixed thereto by means of deformable lugs elastically extending from the internal face of this upper end 81A (ie its face facing the box 30) and cooperating by snap-fastening with windows provided on this post.
De la même manière, l'extrémité inférieure 81 B du corps 81 de chaque garniture latérale 80 est emboîtée sur un tenon respectif (non visible sur les figures) ménagé au niveau du coin supérieur correspondant de la garniture inférieure 70, en y étant fixée par l'intermédiaire de pattes déformables élastiquement s'étendant depuis la face interne de cette extrémité inférieure 81 B (i.e. sa face tournée vers le caisson 30) et coopérant par encliquetage avec des fenêtres ménagées sur ce tenon. Likewise, the lower end 81 B of the body 81 of each side trim 80 is fitted onto a respective lug (not visible in the figures) formed at the corresponding upper corner of the lower trim 70, by being fixed to it by by means of elastically deformable lugs extending from the internal face of this lower end 81 B (ie its face facing the box 30) and cooperating by snap-fastening with windows provided on this post.
Tel qu'illustré sur la figure 2, chaque garniture latérale 80 comporte également deux agrafes métalliques 87 s'étendant depuis la face interne 30 (i.e. tournée vers le caisson) du rebord 83 (ces dernières étant insérées dans des porte-agrafes ménagées sur ce rebord 83) et coopérant par encliquetage avec deux lumières rectangulaires 23 ménagées dans le pourtour 12, 22 de l'ouverture 40 (figures 4 et 5). As illustrated in FIG. 2, each side trim 80 also includes two metal staples 87 extending from the internal face 30 (ie facing the box) of the flange 83 (the latter being inserted into staple holders provided on this ledge 83) and cooperating by snap-fastening with two rectangular openings 23 formed in the periphery 12, 22 of the opening 40 (FIGS. 4 and 5).
Ce clipsage des agrafes 87 permet ainsi d'assurer le maintien dans le temps de ce rebord 83 contre et le long de ce pourtour 12, 22 en limitant sa déformation. This clipping of the staples 87 thus makes it possible to ensure the maintenance over time of this rim 83 against and along this periphery 12, 22 by limiting its deformation.
Toujours en référence à la figure 2, chaque garniture latérale 80 comporte enfin un dispositif de retenue 90 saillant depuis la face interne (i.e. tournée vers le caisson 30) de la portion centrale de la paroi principale 82 du corps 81, à proximité de son bord libre 84. Still with reference to FIG. 2, each lateral lining 80 finally comprises a retaining device 90 projecting from the internal face (ie facing towards the casing 30) of the central portion of the main wall 82 of the body 81, near its edge free 84.
On va maintenant décrire en détails ce dispositif de retenue 90 à l'appui de la figure 3 sur laquelle il est représenté seul. We will now describe in detail this retaining device 90 in support of Figure 3 in which it is shown alone.
Venu avantageusement de moulage d'une seule pièce à partir d'un polymère thermoplastique éventuellement renforcé en fibres naturelles et/ou synthétiques, le dispositif 90 comporte une platine 91 sensiblement rectangulaire destinée à être fixée contre la face interne (i.e. tournée vers le caisson 30) de la paroi principale 82 du corps 81. Advantageously produced by molding in one piece from a thermoplastic polymer optionally reinforced with natural and / or synthetic fibers, the device 90 comprises a substantially rectangular plate 91 intended to be fixed against the internal face (ie facing the box 30 ) of the main wall 82 of the body 81.
Pour ce faire, cette platine 91 présente une pluralité de fentes longitudinales 92 et verticales 93 réparties sur sa surface et prévues pour être traversées par des languettes correspondantes 88, 89 (visibles sur la figure 1) saillant depuis la face interne de la paroi principale 82 de ce corps 81, les extrémités libres de ces languettes 88 étant ensuite soudées sur le pourtour de ces fentes par écrasement à chaud . To do this, this plate 91 has a plurality of longitudinal 92 and vertical slots 93 distributed over its surface and intended to be crossed by corresponding tongues 88, 89 (visible in FIG. 1) projecting from the internal face of the main wall 82 of this body 81, the free ends of these tongues 88 then being welded to the periphery of these slots by hot crushing.
Le dispositif 90 comporte également un fût à section rectangulaire 94 s'étendant transversalement en saillie de la platine 91 et présentant avantageusement une forme légèrement tronconique s'affinant de façon continue et régulière depuis sa base rattachée à la platine 91 jusqu'à son sommet 94A, de sorte à générer des angles de dépouille facilitant le démoulage. The device 90 also comprises a barrel of rectangular section 94 extending transversely projecting from the plate 91 and advantageously having a slightly frustoconical shape refining continuously and regularly from its base attached to the plate 91 to its top 94A , so as to generate draft angles facilitating demolding.
Le sommet 94A du fût 94 porte en son centre un crochet rigide en forme de L 95 s'étendant selon un plan moyen sensiblement horizontal se confondant avec le plan de symétrie horizontal du fût 94. The top 94A of the barrel 94 carries in its center a rigid L-shaped hook 95 extending along a substantially horizontal mean plane merging with the horizontal plane of symmetry of the barrel 94.
Ce crochet 95 comprend une première branche 95A s'étendant transversalement en saillie depuis le centre du sommet 94A et se prolongeant longitudinalement par une seconde branche recourbée 95B orientée vers l'arrière et apte, dans la configuration de service du dispositif 90, à reposer en appui contre le pourtour interne (i.e. tourné vers la garniture latérale 80) du bord arrière 15A d'un orifice 15 ménagé dans une portion latérale de l'encadrement 14 et visible sur la figure 4. This hook 95 comprises a first branch 95A extending transversely projecting from the center of the apex 94A and extending longitudinally by a second curved branch 95B oriented towards the rear and able, in the service configuration of the device 90, to rest in abutment against the internal periphery (ie turned towards the side trim 80) of the rear edge 15A of an orifice 15 formed in a lateral portion of the frame 14 and visible in FIG. 4.
Le sommet 94A du fût 94 porte également deux pattes déformables élastiquement 96 s'étendant parallèlement et symétriquement vis-à-vis du plan moyen du crochet 95, leurs extrémités libres en retour d'équerre formant des épaulements 96A saillant à l'opposé dudit crochet 95 et aptes, dans la configuration de service du dispositif 90, à reposer en appui contre les pourtours internes (i.e. tournés vers la garniture latérale 80) de deux bords supérieur 15B et inférieur 15C opposés de l'orifice 15. The top 94A of the barrel 94 also carries two elastically deformable legs 96 extending parallel and symmetrically with respect to the mean plane of the hook 95, their free ends in return for square forming shoulders 96A protruding opposite said hook 95 and able, in the service configuration of the device 90, to rest in abutment against the internal perimeters (ie turned towards the side lining 80) of two opposite upper 15B and lower 15C edges of the orifice 15.
Le sommet 94A du fût 94 porte enfin, à ses deux extrémités supérieure et inférieure, deux nervures à section en forme de T 97 s'étendant symétriquement vis-à-à-vis du plan moyen du crochet 95 et dont les extrémités libres sont conformées de sorte à, dans la configuration de service du dispositif 90, reposer en appui contre les pourtours externes (i.e. tournés à l'opposé de la garniture latérale 80) de deux bords supérieur 15B et inférieur 15C opposés de l'orifice 15. The top 94A of the barrel 94 finally carries, at its two upper and lower ends, two ribs of T-shaped section 97 extending symmetrically with respect to the mean plane of the hook 95 and whose free ends are shaped so that, in the service configuration of the device 90, rest in abutment against the outer edges (ie turned away from the side trim 80) of two opposite upper 15B and lower 15C edges of the orifice 15.
Lors du montage d'une garniture latérale 80, le crochet 95 est tout d'abord inséré au travers d'un orifice 15 ménagé dans une portion latérale de l'encadrement 14 de la peau extérieure 10, puis déplacé longitudinalement vers l'arrière jusqu'à ce que sa première branche 94A vienne buter contre le bord arrière 15A de cet orifice 15. When mounting a side fitting 80, the hook 95 is firstly inserted through an orifice 15 formed in a lateral portion of the frame 14 of the outer skin 10, then moved longitudinally backwards until 'that its first branch 94A abuts against the rear edge 15A of this orifice 15.
Les deux pattes 96 sont ensuite encliquetées à force dans ce même orifice 15 (ces dernières se déformant en pivotant légèrement l'une vers l'autre de sorte à autoriser le passage des épaulements 96A) de sorte à amener le dispositif 90 dans sa configuration de service dans laquelle le pourtour de l'orifice 15 est pris en sandwich entre d'une part les nervures 97 et d'autre part la seconde branche 95B du crochet 95 et les deux épaulements 96A des pattes 96. The two tabs 96 are then snapped into this same orifice 15 (the latter deforming by pivoting slightly towards each other so as to allow the passage of the shoulders 96A) so as to bring the device 90 in its configuration of service in which the periphery of the orifice 15 is sandwiched between on the one hand the ribs 97 and on the other hand the second branch 95B of the hook 95 and the two shoulders 96A of the legs 96.
Le bord libre 84 de la paroi principale 82 de la garniture latérale 80 venant en affleurement de la lunette arrière 50 est ainsi empêché de s'écarter de l'encadrement 14 de la peau extérieure 10. On notera que la hauteur des nervures 97 peut être facilement ajustée par retrait ou ajout de matière dans le moule d'injection servant à fabriquer le dispositif 90, de sorte à s'adapter à l'épaisseur de la tôle constituant l'encadrement 14 pour éviter l'apparition de bruits parasites dus à un jeu trop important. The free edge 84 of the main wall 82 of the side lining 80 which is flush with the rear window 50 is thus prevented from moving away from the frame 14 of the outer skin 10. It will be noted that the height of the ribs 97 can be easily adjusted by removing or adding material to the injection mold used to manufacture the device 90, so as to adapt to the thickness of the sheet forming the frame 14 for avoid the appearance of extraneous noise due to excessive play.
On remarquera également que le fût 94 présente une découpe 98 s'étendant transversalement dans la zone en regard du crochet 95, entre son sommet 94A et la platine 91, de sorte à faciliter le moulage du dispositif 90. It will also be noted that the barrel 94 has a cutout 98 extending transversely in the zone opposite the hook 95, between its top 94A and the plate 91, so as to facilitate the molding of the device 90.
Selon des variantes de réalisation non représentées, le dispositif de retenue est dépourvu de fentes telles que 92 et 93 : ce dernier étant destiné à être fixé par collage contre la face interne de la paroi principale du corps de la garniture latérale. According to variants not shown, the retaining device is devoid of slots such as 92 and 93: the latter being intended to be fixed by gluing against the internal face of the main wall of the body of the side trim.
Selon d'autres variantes de réalisation non représentées, le nombre et/ou l'agencement du crochet et/ou des pattes sont différents. According to other alternative embodiments not shown, the number and / or the arrangement of the hook and / or of the tabs are different.
D'une manière générale, on rappelle que la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution à la portée de l'homme du métier. In general, it is recalled that the present invention is not limited to the embodiments described and shown, but encompasses any variant within the reach of the skilled person.
