Description

Dispositif de fixation d'une garniture sur une structure de véhicule Device for attaching a lining to a vehicle structure
Domaine technique de l'inventionTechnical field of the invention
L'invention est relative à un dispositif de fixation d'une garniture sur une structure de véhicule, comprenant un élément intermédiaire de montage solidaire de la garniture et un corps principal équipé de moyens de fixation à la structure et de moyens d'accrochage par encliquetage de l'élément intermédiaire de montage.The invention relates to a device for attaching a lining to a vehicle structure, comprising an intermediate integral mounting member of the lining and a main body equipped with fastening means to the structure and snap fastening means of the intermediate mounting element.
État de la techniqueState of the art
Ce type de dispositifs de fixation est particulièrement utilisé lors de l'assemblage des garnitures qui constituent les encadrements des fenêtres de voiture. Suivant les variantes de réalisation, soit l'élément intermédiaire de montage est directement constitué par une partie de la garniture, soit la garniture et l'élément intermédiaire de montage sont deux pièces indépendantes.This type of fastening devices is particularly used when assembling the fittings that constitute the frames of the car windows. According to the embodiments, either the intermediate mounting element is directly constituted by a portion of the gasket, or the gasket and the intermediate mounting element are two independent parts.
Le document EP-A-1211115 décrit un dispositif de fixation comportant un guide supérieur et un guide inférieur, tous deux fixes, et qui délimitent une fente de réception d'une languette de l'élément intermédiaire de montage. La largeur de la fente de réception est constante. Les moyens d'accrochage par encliquetage sont réalisés par des doigts transversaux de verrouillage qui s'étendent obliquement dans la fente de réception. L'extrémité libre de chaque doigt de verrouillage comporte une ouverture de verrouillage. Au moins un crochet est prévu en saillie de la languette pour venir s'engager dans l'ouverture de verrouillage lors de l'insertion de la languette dans la fente de réception. Le crochet assure alors la retenue de l'élément intermédiaire de montage. L'engagement du crochet de la languette dans l'ouverture de verrouillage du doigt est dû au retour élastique de la matière du doigt après un mouvement transversal de flexion du doigt provoqué par l'insertion de la languette.EP-A-1211115 discloses a fixing device comprising an upper guide and a lower guide, both fixed, and which define a slot for receiving a tab of the intermediate mounting element. The width of the reception slot is constant. The snap fastening means are made by transverse locking fingers which extend obliquely in the receiving slot. The free end of each locking pin has a locking opening. At least one hook is provided projecting from the tongue to engage in the locking opening during the insertion of the tongue into the receiving slot. The hook then ensures the retention of the intermediate mounting element. The hook engagement of the tongue in the finger lock opening is due to the elastic return of the material of the finger after a transverse movement of bending of the finger caused by the insertion of the tongue.
Pour permettre qu'un effort faible d'insertion de la languette produise une grande amplitude dans le mouvement de flexion du doigt, il est nécessaire que l'extrémité du doigt opposée à l'extrémité libre soit raccordée à un point du coφs principal qui est transversalement très en retrait de la fente de réception par comparaison avec la largeur de ladite fente. Il en résulte qu'au moins l'un des guides doit être constitué par une pluralité de tronçons individuels alignés de manière à délimiter des ouvertures de passage pour les doigts vers l'intérieur de la fente. Les dimensions d'une ouverture de passage sont grandes pour autoriser une grande amplitude dans le mouvement de flexion du doigt qui la traverse.To allow a low insertion force of the tongue to produce a large amplitude in the bending motion of the finger, it is necessary that the end of the finger opposite the free end is connected to a point of the main coφs which is transversely far back from the receiving slot in comparison with the width of said slot. As a result, at least one of the guides must be constituted by a plurality of individual sections aligned so as to define passage openings for the fingers towards the inside of the slot. The dimensions of a passage opening are large to allow a large amplitude in the bending movement of the finger that passes through it.
Ce dispositif de fixation connu n'est pas totalement satisfaisant car chaque ouverture de passage constitue un dégagement de matière qui influe directement sur la précision du guidage de la languette pendant son insertion. Ces dégagements de matière rendent notamment possible d'insérer involontairement la languette avec un léger biais par rapport à la direction longitudinale de la fente, jusqu'à parfois venir traverser une ouverture de passage et plier le doigt correspondant. Avec un tel biais, il arrive fréquemment qu'au moins l'une des portions individuelles qui constitue le guide tronçonné soit pliée par l'extrémité de la languette à cause de la force d'insertion. Dans le cas où la portion individuelle se plie vers l'extérieur de la fente, la fiabilité de l'accrochage réalisé n'est pas correcte car le maintien transversal de la languette dans la fente n'est pas bien garanti. Dans le cas où la portion individuelle se plie vers l'intérieur de la fente, l'accrochage est impossible et il est nécessaire de remplacer le corps principal. Le pliage d'une portion individuelle intervient fortuitement de manière très rapide à cause de sa faible longueur comptée dans la direction longitudinale de la fente. Ces risques sont renforcés par le fait que dans de nombreuses applications, ies dispositifs de fixation sont localisés à des endroits peu accessibles, voire invisibles. Lors d'un montage en aveugle, l'opérateur insère la languette dans la fente de réception sans pouvoir contrôler visuellement l'opération, ni son résultat.This known fixing device is not completely satisfactory because each passage opening constitutes a release of material that directly affects the accuracy of the guide of the tongue during its insertion. These clearances of material make it possible in particular to insert the tongue involuntarily with a slight bias relative to the longitudinal direction of the slot, until sometimes come through a passage opening and bend the corresponding finger. With such bias, it frequently happens that at least one of the individual portions which constitutes the cut-off guide is bent by the end of the tongue because of the insertion force. In the case where the individual portion bends towards the outside of the slot, the reliability of the hooking achieved is not correct because the transverse retention of the tongue in the slot is not well guaranteed. In the case where the individual portion bends inwardly of the slot, the attachment is impossible and it is necessary to replace the main body. The folding of an individual portion occurs fortuitously very quickly because of its short length counted in the longitudinal direction of the slot. These risks are reinforced by the fact that in many applications, the fixing devices are located in inaccessible or even invisible places. During a blind assembly, the operator inserts the tab into the receiving slot without being able to visually control the operation or its result.
Objet de l'inventionObject of the invention
L'objet de l'invention consiste à réaliser un dispositif de fixation facile à mettre en œuvre et qui augmente la fiabilité de l'accrochage réalisé entre le corps principal et l'élément intermédiaire de montage.The object of the invention is to provide a fixing device easy to implement and increases the reliability of the hooking formed between the main body and the intermediate mounting element.
Selon l'invention, ce but est atteint par le fait que les moyens d'accrochage par encliquetage comportent : des longerons de guidage interne et externe, parallèles, délimitant une fente de réception d'une languette de l'élément intermédiaire de montage, des moyens souples et élastiques de raccordement d'une âme centrale du longeron externe au corps principal, pour assurer une mobilité de l'âme centrale dans le sens de la largeur de la fente de réception, au moins un crochet de retenue solidaire de l'âme centrale, en saillie vers l'intérieur de la fente de réception, et destiné à s'insérer automatiquement dans une ouverture de verrouillage de ladite languette en fin de course d'insertion de la languette dans la fente de réception.According to the invention, this object is achieved by the fact that the snap-fastening means comprise: parallel internal and external guide rails delimiting a slot for receiving a tongue of the intermediate mounting element; flexible and resilient means for connecting a central core of the outer spar to the main body, to ensure a mobility of the central core in the width direction of the receiving slot, at least one retaining hook integral with the core central, projecting inwardly of the receiving slot, and intended to be inserted automatically into a locking opening of said tab end insertion insertion race of the tongue in the receiving slot.
Les longerons sont constitués par une paroi continue de matière sur toute la longueur de la fente de réception et assurent ainsi un guidage précis de la languette pendant son insertion, de manière à l'orienter fixement dans la direction longitudinale de la fente de réception. Les risques d'insertion de biais sont supprimés. La largeur de la fente de réception délimitée par les longerons de guidage est variable au niveau de l'âme centrale du longeron externe, le rappel élastique des moyens de raccordement assurant un léger serrage de la languette lors de son insertion par pression de l'âme centrale. Ces aspects contribuent à renforcer le maintien transversal de la languette pendant son insertion, et donc son guidage. La garantie d'un bon guidage de la languette lors de son insertion dans la fente de réception permet naturellement de s'assurer de l'engagement correct du crochet de retenue dans l'ouverture de verrouillage, et fiabilise en conséquence l'accrochage par encliquetage de l'élément intermédiaire de montage. En d'autres termes, l'opération d'insertion de la languette de l'élément intermédiaire de montage dans la fente de réception du corps principal jusqu'en fin de course suffit à s'assurer de la qualité et de la fiabilité de l'assemblage réalisé entre ces deux pièces.The longitudinal members are constituted by a continuous wall of material over the entire length of the receiving slot and thus provide precise guidance of the tongue during its insertion, so as to orient it fixedly in the longitudinal direction of the receiving slot. The risks of bias insertion are removed. The width of the receiving slot defined by the guide rails is variable at the central web of the spar external, the elastic return of the connecting means ensuring a slight tightening of the tongue during insertion by pressing the central core. These aspects contribute to reinforcing the transverse retention of the tongue during its insertion, and thus its guidance. The guarantee of a good guiding of the tongue when it is inserted into the receiving slot naturally makes it possible to ensure the correct engagement of the retaining hook in the locking aperture, and thus makes the snap fastener more reliable. of the intermediate mounting element. In other words, the insertion operation of the tongue of the intermediate mounting element in the receiving slot of the main body to the end of stroke is sufficient to ensure the quality and reliability of the assembly made between these two parts.

La garniture 14 constitue par exemple un morceau de l'encadrement d'une fenêtre du véhicule et la face visible de la garniture 14 assure une finition esthétique.Description of a preferred embodiment of the invention An attachment device 10 is shown in FIGS. 1 to 4, comprising a main body 11 generally elongate in a longitudinal direction denoted by D1, and an intermediate mounting element 12 (FIG. 4) consisting in the example of a tongue 13. Fixing device 10 ensures the attachment and maintenance of a lining 14 on a vehicle structure 15, by interposing between these two parts. The main body 11 is fixed to the structure 15 in a manner described below, and the intermediate mounting element 12, that is to say here the tongue 13, is directly formed projecting from the hidden face of the trim 14 which is in the form of a strip. The lining 14 equipped with the tongue 13, as well as the main body 11, are obtained by molding a plastic material. The lining 14 is for example a piece of the frame of a vehicle window and the visible face of the lining 14 provides an aesthetic finish.
Sans sortir du cadre de l'invention, l'élément intermédiaire de montage 12 peut être constitué par une pièce indépendante de la garniture 14. Dans ce cas, la languette 13 est conçue comme une partie protubérante solidaire de l'élément intermédiaire de montage 12 qui peut ainsi assurer d'autres fonctions comme l'étanchéité ou l'amortissement des vibrations. L'élément intermédiaire de montage 12 peut être fixé à la garniture 14 par tout moyen approprié de clipage, de soudage ou de collage.Without departing from the scope of the invention, the intermediate mounting element 12 may be constituted by a piece independent of the lining 14. In this case, the tongue 13 is designed as a protruding portion integral with the intermediate mounting element 12 which can thus provide other functions such as sealing or damping vibrations. The intermediate mounting member 12 may be attached to the liner 14 by any suitable means of clipping, welding or gluing.
Pour permettre la mise en place et la fixation du corps principal 11, la structure 15 présente une surface en palier 16 plane, équipée de deux goujons à tête 17 disposés en saillie. Les goujons à tête 17 sont soudés à la surface en palier 16 et le corps principal 11 est fixé aux goujons à tête 17. A cet effet, le corps principal 11 se compose d'une poutre châssis 18 globalement de forme rectangulaire orientée selon D1 et destinée à venir en appui par sa face arrière sur la surface en palier 16 par maintien grâce aux goujons à tête 17. A l'une de ses extrémités, la poutre châssis 18 comporte une première lumière 19 dirigée selon D1 pour déboucher sur le petit côté correspondant de la poutre châssis 18. A son autre extrémité, une deuxième lumière 20 s'étend vers le bas selon une direction latérale D2 de la poutre châssis 18, perpendiculaire à D1, pour déboucher sur le grand côté inférieur de la poutre châssis 18. La largeur des lumières 19, 20 est inférieure au diamètre de la tête des goujons à tête 17 et supérieure au diamètre de leur corps cylindrique reliant la tête à la surface en palier 16. La direction transversale D3 du corps principal 11 correspond à la direction simultanément perpendiculaire aux directions longitudinale D1 et latérale D2.To allow the establishment and attachment of the main body 11, the structure 15 has a flat bearing surface 16, equipped with two studs 17 projecting head. The studs 17 are welded to the bearing surface 16 and the main body 11 is fixed to the studs 17. For this purpose, the main body 11 consists of a frame beam 18 generally of rectangular shape oriented according to D1 and intended to be supported by its rear face on the bearing surface 16 by holding with the studs 17. At one of its ends, the frame beam 18 has a first slot 19 directed along D1 to lead to the short side corresponding beam chassis 18. At its other end, a second light 20 extends downwardly in a lateral direction D2 of the chassis beam 18, perpendicular to D1, to open on the large lower side of the beam frame 18. The width of the lights 19, 20 is smaller than the diameter of the head studs with a head 17 and greater than the diameter of their cylindrical body connecting the head to the bearing surface 16. The transverse direction D3 of the main body 11 corresponds to the direction simultaneously perpendicular to the longitudinal directions D1 and lateral D2.
Lors de la fixation du corps principal 11 sur la structure 15, la poutre châssis 18 est mise en appui contre la surface en palier 16. Puis l'un des goujon 17 est inséré dans la première lumière 19 par engagement de la poutre châssis 18 sous la tête de ce goujon. Par rotation du corps principal 11 vers le bas autour du goujon déjà engagé, l'autre goujon 17 est ensuite inséré dans la deuxième lumière 20. Le goujon 17 inséré dans la première lumière 19 assure le maintien en position selon la direction D2 du corps principal 11, l'autre goujon 17 le maintenant en position dans la direction D1. La longueur de la deuxième lumière 20 règle l'orientation relative du corps principal 11 par rapport à la structure 15 dans le plan de la surface en palier 16. Les bords de chaque lumière 19, 20 présentent un épaulement de manière à constituer un logement de la tête des goujons à tête 17 après la mise en place du corps principal 11. La tête est donc noyée dans la matière constitutive des portions d'extrémités de la poutre châssis 18 pour supprimer les risques d'accrochage involontaire.When fixing the main body 11 on the structure 15, the chassis beam 18 is pressed against the bearing surface 16. Then one of the stud 17 is inserted into the first slot 19 by engaging the chassis beam 18 under the head of this stud. By rotating the main body 11 downwards around the bolt already engaged, the other bolt 17 is then inserted into the second lumen 20. The bolt 17 inserted in the first lumen 19 maintains the position in the direction D2 of the main body 11, the other stud 17 keeps it in position in the direction D1. The length of the second lumen 20 regulates the relative orientation of the main body 11 relative to the structure 15 in the plane of the bearing surface 16. The edges of each lumen 19, 20 have a shoulder so as to constitute a housing of head head studs 17 after the establishment of the main body 11. The head is embedded in the constituent material of the end portions of the frame beam 18 to eliminate the risk of accidental snagging.
La partie centrale de la poutre châssis 18 suivant la direction D1 , raccordant les portions d'extrémités où sont pratiquées les lumières 19, 20, est constituée par un profilé interne 21 droit de section en V très ouvert. Plus précisément, le profilé interne 21 est constitué par une paroi inclinée interneThe central portion of the chassis beam 18 in the direction D1, connecting the end portions where the slots 19, 20 are formed, is constituted by a straight internal profile 21 of very open V section. More specifically, the internal section 21 is constituted by an internal inclined wall
22 dont le bord supérieur matérialise le grand côté supérieur de la poutre châssis 18 et dont le bord inférieur est connecté à une paroi de base interne22 whose upper edge materializes the large upper side of the frame beam 18 and whose lower edge is connected to an inner base wall
23 du profilé interne 21. Le bord inférieur de la paroi de base interne 23 matérialise le grand côté inférieur de la poutre châssis 18. La paroi de base interne 23 s'étend dans le plan contenant les directions longitudinale D1 et latérale D2. La paroi inclinée interne 22 s'éloigne de la direction latérale D2 en s approchant de son bord supérieur. La face du profilé interne 21 qui est destinée à faire face à la surface en palier 16 comporte une pluralité de nervures de renfort 24 dont l'arête est coplanaire avec la face arrière des portions d'extrémités de la poutre châssis 18. Les nervures de renfort 24 suppriment toute possibilité de flexion du profilé interne 21. La paroi inclinée interne 22 constitue ce qui sera appelé par la suite un longeron de guidage interne 25.23 of the inner profile 21. The lower edge of the inner base wall 23 materializes the large lower side of the frame beam 18. The base wall internal 23 extends in the plane containing the longitudinal directions D1 and lateral D2. The inner inclined wall 22 moves away from the lateral direction D2 as it approaches its upper edge. The face of the inner profile 21 which is intended to face the bearing surface 16 comprises a plurality of reinforcing ribs 24 whose edge is coplanar with the rear face of the end portions of the chassis beam 18. The ribs reinforcement 24 eliminates any possibility of bending of the inner profile 21. The inner inclined wall 22 constitutes what will be called hereinafter an inner guide spar 25.
Le corps principal 11 comporte en outre un profilé externe 26 parallèle au profilé interne 21 et raccordée à ses extrémités à des ailes de support 27a, 27b disposées transversalement selon D3, elles-mêmes raccordées aux extrémités du profilé interne 21. Le profilé externe 26 présente également une section en V très ouvert de telle manière qu'il est constitué par une paroi inclinée externe 28 parallèle à la paroi inclinée interne 22 et par une paroi de base externe 29 parallèle à la paroi de base interne 23. La paroi inclinée externe 28 constitue ce qui sera appelé par la suite un longeron de guidage externe 30. L'épaisseur du profilé externe 26 est beaucoup plus faible que celle du profilé interne 21 , dans un but qui sera détaillé plus loin.The main body 11 further comprises an outer profile 26 parallel to the inner profile 21 and connected at its ends to the support wings 27a, 27b arranged transversely along D3, themselves connected to the ends of the inner profile 21. The outer profile 26 has also a very open V-shaped section such that it consists of an outer inclined wall 28 parallel to the inner inclined wall 22 and an outer base wall 29 parallel to the inner base wall 23. The outer inclined wall 28 is what will be called thereafter an outer guide beam 30. The thickness of the outer section 26 is much smaller than that of the inner section 21, for a purpose which will be detailed later.
L'aile de support 27a disposée du côté de la deuxième lumière 20 constitue également l'une des branches latérales d'une aile d'encadrement 31 sensiblement en forme de U dont l'autre branche latérale est raccordée à la poutre châssis 18 du côté opposé à l'aile de support 27a par rapport à la deuxième lumière 20. L'aile d'encadrement 31 délimite, en combinaison avec la poutre châssis 18, un volume sensiblement rectangulaire avec des ouvertures inférieure 32 et supérieure 33 suivant la direction latérale D2.The support wing 27a disposed on the side of the second lumen 20 also constitutes one of the side branches of a substantially U-shaped frame wing 31 whose other lateral branch is connected to the frame beam 18 on the side. opposite to the support wing 27a with respect to the second light 20. The frame wing 31 delimits, in combination with the chassis beam 18, a substantially rectangular volume with lower openings 32 and upper 33 in the lateral direction D2 .
Comme l'illustre la figure 3, une languette de retenue 34 flexible s'étend en travers de l'ouverture inférieure 32 depuis le bord inférieur de l'aile constituant la base de l'aile d'encadrement 31. La languette de retenue 34 est inclinée vers le haut en s'approchant de la deuxième lumière 20. Dans cette configuration, la languette de retenue 34 se plie lorsque le goujon 17 correspondant vient s'engager dans la deuxième lumière 20. En fin d'engagement, le rappel élastique de la matière constitutive de la languette de retenue 34 permet par exemple à son extrémité libre de revenir automatiquement dans une position de blocage en dessous de la tête du goujon 17, dans laquelle elle constitue une butée pour le goujon 17 qui ne peut alors plus se dégager de la lumière 20. Dans d'autres variantes, l'extrémité libre revient automatiquement dans une position d'appui sur la tête du goujon 17, dans laquelle la languette 34 supprime les jeux de montage entre la structure 15 et le corps principal 11, et crée un amortissement des vibrations entre ces éléments. A défaut, ces jeux et vibrations seraient susceptibles de générer des vibrations de la garniture 14 gênantes à l'intérieur de l'habitacle du véhicule.As illustrated in FIG. 3, a flexible retaining tab 34 extends across the lower opening 32 from the lower edge of the wing constituting the base of the framing flange 31. The retaining tab 34 is inclined upwardly approaching the second lumen 20. In this configuration, the retaining tongue 34 bends when the corresponding stud 17 engages in the second lumen 20. At the end of engagement, the elastic return of the constituent material of the retaining tongue 34 allows for example at its free end to automatically return to a locking position below the head of the stud 17, in which it constitutes a stop for the stud 17 which can then no longer be In other variants, the free end automatically returns to a position of support on the head of the stud 17, in which the tongue 34 eliminates the mounting clearance between the structure 15 and the main body 11 , and creates a vibration damping between these elements. Otherwise, these games and vibrations would be likely to generate vibrations of the lining 14 troublesome inside the passenger compartment of the vehicle.
Les longerons de guidage interne 25 et externe 30 sont parallèles et délimitent une fente de réception 35 de la languette 13 de l'élément intermédiaire de montage 12. L'orientation des parois inclinées interne 22 et externe 28 est liée notamment aux formes de la structure 15, à l'accessibilité de la zone de montage, et à l'orientation de l'élément que la garniture 14 est destinée à recouvrir.The inner and outer guide rails 25 and 25 are parallel and delimit a receiving slot 35 of the tongue 13 of the intermediate mounting member 12. The orientation of the inner inclined walls 22 and outer 28 is related in particular to the shapes of the structure 15, the accessibility of the mounting area, and the orientation of the element that the liner 14 is intended to cover.
A proximité de ses extrémités, le profilé externe 26 présente une inflexion 36a, 36b dirigée transversalement du côté opposé au profilé interne 21. La partie centrale de la paroi externe 28 suivant la direction longitudinale D1 , les inflexions 36a, 36b délimitent une âme centrale 37 du longeron de guidage externe 30, qui est plane et parallèle au longeron de guidage interne 25. L'épaisseur des inflexions 36a, 36b (qui correspond à l'épaisseur du profilé externe 26) est choisie en fonction de leur matière constitutive, de manière que les inflexions 36a, 36b soient souples et élastiques pour constituer une réserve de matière suffisante afin d'assurer une mobilité de l'âme centrale 37 dans le sens de la largeur de la fente de réception 35, c'est-à-dire dans la direction transversale D3.Near its ends, the outer profile 26 has an inflection 36a, 36b directed transversely on the opposite side to the inner profile 21. The central portion of the outer wall 28 in the longitudinal direction D1, the inflections 36a, 36b delimit a central core 37 the outer guide beam 30, which is flat and parallel to the inner guide spar 25. The thickness of the inflections 36a, 36b (which corresponds to the thickness of the outer profile 26) is chosen according to their constituent material, so that the inflections 36a, 36b are flexible and elastic to form a reserve of sufficient material to ensure mobility of the central core 37 in the direction of the width of the receiving slot 35, that is to say in the transverse direction D3.
Sur sa face orientée vers la paroi inclinée interne 22, l'âme centrale 37 comporte trois crochets de retenue 38 qui font saillie vers l'intérieur de la fente de réception 35. En référence à la figure 4, chaque crochet de retenue 38 s'étend depuis le bord supérieur de l'âme centrale 37 avec, du côté supérieur, un chanfrein d'entrée 40 sensiblement orienté vers le fond de la fente de réception 35. Le crochet de retenue 38 comporte du côté inférieur une surface d'arrêt 41 s'étendant perpendiculairement depuis l'âme centrale 37. Les crochets de retenue 38 sont destinés à coopérer avec une ouverture de verrouillage 39 prévue dans la languette 13 de la manière décrite ci- dessous.On its face facing the inner inclined wall 22, the central core 37 has three retaining hooks 38 which protrude inwardly of the receiving slot 35. Referring to FIG. 4, each retaining hook 38 extends from the upper edge of the central core 37 with, on the upper side, an inlet chamfer 40 substantially oriented towards the bottom of the receiving slot 35. The retaining hook 38 has on the lower side a stop surface 41 extending perpendicularly from the central core 37. The retaining hooks 38 are intended to cooperate with a locking aperture 39 provided in the tongue 13 in the manner described below.
Lorsque l'opérateur chargé du montage de la garniture 14 sur la structure 15 désire accrocher la garniture 14 sur le corps principal 11 préalablement fixé à la structure de véhicule 15, il vient insérer la languette 13 dans la fente de réception 35. L'extrémité de la languette 13 vient s'appuyer et glissent sur les chanfreins d'entrée 40 des crochets de retenue 38. L'inclinaison des chanfreins d'entrée 40 est telle que le mouvement d'insertion de la languette 13 provoque ensuite l'écartement de l'âme centrale 37 tandis que les inflexions 36a, 36b se déforment élastiquement. Le rappel élastique de la matière constitutive des inflexions 36a, 36b assure un léger serrage de la languette 13 lors de son insertion, par une pression de l'âme centrale 37 au niveau des lignes de contact entre les chanfreins d'entrée 40 et l'extrémité de la languette 13. Cette pression de l'âme centrale 37 garantit un maintien automatique de la languette 13 contre le longeron interne 25 pendant l'insertion. Simultanément, le longeron interne 25 en combinaison avec les portions d'extrémités du longeron externe 30 situées de part et d'autre des inflexions 36a, 36b assurent un guidage très précis de la languette 13 de manière à l'orienter fixement dans la direction longitudinale D1 de la fente de réception 35. Ce guidage de la languette 13, renforcé par la pression transversale de l'âme centrale 37, supprime les risques d'insertion de biais de la languette 13.When the operator responsible for mounting the lining 14 on the structure 15 wishes to hang the lining 14 on the main body 11 previously attached to the vehicle structure 15, it comes to insert the tongue 13 in the receiving slot 35. The end of the tongue 13 comes to bear and slide on the input chamfer 40 of the retaining hooks 38. The inclination of the input chamfer 40 is such that the insertion movement of the tongue 13 then causes the separation of the central core 37 while the inflections 36a, 36b deform elastically. The elastic return of the material constituting inflections 36a, 36b ensures a slight tightening of the tongue 13 during its insertion, by a pressure of the central core 37 at the level of the contact lines between the input chamfers 40 and the end of the tongue 13. This pressure of the central core 37 ensures automatic maintenance of the tongue 13 against the inner spar 25 during insertion. Simultaneously, the inner spar 25 in combination with the end portions of the outer spar 30 located on either side of the inflections 36a, 36b provide a very precise guide of the tongue 13 so as to orient it fixedly in the longitudinal direction. D1 of the receiving slot 35. This guide of the tongue 13, reinforced by the pressure transverse of the central core 37, eliminates the risk of bias insertion of the tongue 13.
En fin de course d'insertion de la languette 13, le rappel élastique des inflexions 36a, 36b provoque l'insertion des crochets de retenue 38 dans l'ouverture de verrouillage 39 de la languette 13 au moment où le bord inférieur de l'ouverture de verrouillage 39 dépasse le sommet des crochets de retenue 38. La languette 13 est accrochée car tout effort de traction sur la languette 13 provoque par la suite l'entrée en contact du bord inférieur de l'ouverture de verrouillage 39 et des surfaces d'arrêt 41.At the end of the insertion stroke of the tongue 13, the elastic return of the inflections 36a, 36b causes the insertion of the retaining hooks 38 into the locking aperture 39 of the tongue 13 at the moment when the lower edge of the opening 39 is protruding from the top of the retaining hooks 38. The tongue 13 is hooked because any tensile force on the tongue 13 subsequently causes the lower edge of the locking aperture 39 and the surfaces of the tongue to come into contact with each other. stop 41.
La garantie automatique d'un bon guidage de la languette 13 lors de son insertion dans la fente de réception 35 facilite cette opération car aucune précaution particulière n'est requise de la part de l'usager, et permet de s'assurer que les crochets de retenue 38 sont obligatoirement insérés dans l'ouverture de verrouillage 39 au moment de la fin de course d'insertion de la languette 13, ce qui fiabilise l'accrochage par encliquetage de l'élément intermédiaire de montage 12. En d'autres termes, l'insertion jusqu'en fin de course de la languette 13 de l'élément intermédiaire de montage 12 dans la fente de réception 35 du corps principal 11 suffit à s'assurer de la qualité et de la fiabilité de l'assemblage réalisé entre ces deux pièces 11, 12. The automatic guarantee of good guiding of the tongue 13 when it is inserted into the receiving slot 35 facilitates this operation since no particular precaution is required on the part of the user, and makes it possible to ensure that the hooks 38 are necessarily inserted into the locking aperture 39 at the insertion end of travel of the tab 13, which makes the snap-fastening of the intermediate mounting element 12 more reliable. In other words the insertion of the tongue 13 of the intermediate mounting element 12 into the receiving slot 35 of the main body 11 until the end of the stroke is sufficient to ensure the quality and reliability of the assembly made between these two pieces 11, 12.
