Abstract

The shoe has an upper formed of two pieces that are assembled by gluing. A set of carriers (121) is constituted of a strap made of synthetic textile material and disposed face-to-face along the length of a lacing zone (119). The carriers are assembled between two glue layers (130, 131) of the upper. A band (132) permits perfect folding and assembling of carriers at the upper.

Description

L'invention se rapporte au domaine des chaussures, et plus particulièrement à celui des chaussures de sport.The invention relates to the field of shoes, and more particularly to that of sports shoes.

Les chaussures de sport comportent une semelle qui peut être souple ou rigide et sur laquelle est montée une tige qui recouvre le pied de l'utilisateur. Cette tige est la plupart du temps réalisée sous la forme de plusieurs pièces qui sont découpées et assemblées entre elles de manière à former une enveloppe tridimensionnelle la plus proche possible de la forme du pied. Généralement, la forme de ces pièces et les matériaux qui les constituent sont dictés par la position desdites pièces et par la fonction que l'on veut leur faire remplir. La tige peut aussi comporter des éléments rapportés tels qu'un renfort d'extrémité avant, généralement en cuir épais ou en caoutchouc.Sports shoes have a sole that can be flexible or rigid and on which is mounted a rod that covers the foot of the user. This rod is mostly made in the form of several pieces that are cut and assembled together to form a three-dimensional envelope as close as possible to the shape of the foot. Generally, the shape of these parts and the materials that constitute them are dictated by the position of said parts and the function that we want them to fill. The rod may also include inserts such as a front end brace, usually thick leather or rubber.

Dans la plupart des chaussures de sport, la tige comporte des quartiers latéraux internes et externes qui sont destinés à être rapprochés l'un de l'autre par un système de serrage, le plus souvent un laçage. Ces quartiers sont alors séparés par une fente longitudinale en dessous de laquelle peut s'étendre une languette de confort.In most sports shoes, the upper has internal and external lateral quarters which are intended to be brought closer to one another by a clamping system, most often a lacing. These neighborhoods are then separated by a longitudinal slot below which can extend a tab of comfort.

Dans certains types de chaussures, notamment les chaussures de ski de fond ou certaines chaussures de randonnée, la tige comporte un rabat de protection qui vient recouvrir le système de laçage, mais qui peut s'écarter pour permettre le laçage et le délaçage, donc le chaussage et le déchaussage de la chaussure. Un tel rabat est décrit dans le document EP 1 310 182 . Ce rabat de protection est particulièrement utile pour les chaussures destinées à être portées dans la neige car il évite que la neige puisse s'introduire dans la chaussure au niveau de la fente qui sépare les quartiers latéraux de la tige.In certain types of shoes, including cross-country ski boots or certain hiking boots, the upper has a protective flap which covers the lacing system, but which can move apart to allow lacing and delamination, so the donning and loosening the shoe. Such a flap is described in the document EP 1 310 182 . This protective flap is particularly useful for shoes intended to be worn in the snow because it prevents the snow can be introduced into the shoe at the slot that separates the lateral areas of the rod.

Dans une conception classique de la tige, les différentes pièces qui la constituent sont en principe assemblées par couture (que l'on appelle aussi piquage). Pour cela, les pièces à assembler présentent des portions chevauchantes dans lesquelles deux pièces adjacentes sont superposées. Une couture traversante, visible des deux côtés de la superposition, lie les deux pièces l'une à l'autre. Avec une couture traversante, le fil de couture est exposé sur les deux faces, donc notamment sur la face externe de la tige. Il se trouve ainsi exposé aux agressions extérieures et notamment aux frottements qui peuvent user le fil et donc provoquer la rupture de la couture. De même, il est connu que les coutures traversantes sont des points d'entrée de l'humidité dans la chaussure.In a conventional design of the stem, the various parts that constitute it are in principle assembled by stitching (also called stitching). For this, the parts to be assembled have overlapping portions in which two adjacent parts are superimposed. A through seam, visible on both sides of the overlay, binds the two pieces to each other. With a through seam, the sewing thread is exposed on both sides, especially on the outer face of the shank. It is thus exposed to external aggressions and especially to friction that can wear the thread and thus cause breakage of the seam. Similarly, it is known that the through seams are points of entry of moisture into the shoe.

Un but de la présente invention est de proposer une nouvelle conception de l'assemblage de certaines pièces de la tige d'une chaussure.An object of the present invention is to propose a new design of the assembly of certain parts of the upper of a shoe.

Un but notamment recherché est d'augmenter la résistance à l'usure et/ou la résistance à la pénétration de l'humidité.A purpose particularly sought is to increase the wear resistance and / or resistance to penetration of moisture.

Un autre des buts recherchés est de fournir une nouvelle esthétique de la chaussure.Another goal is to provide a new aesthetic of the shoe.

Ce ou ces buts sont atteints dans la chaussure selon l'invention, qui est du type comportant une tige et une semelle, notamment en ce que la tige comporte au moins deux pièces qui sont assemblées l'une à l'autre au moins en partie par une zone de collage.This or these goals are achieved in the shoe according to the invention, which is of the type comprising a rod and a sole, in particular in that the rod comprises at least two parts which are assembled to each other at least partly by a bonding area.

L'invention trouvera une application dans le fait d'assembler par collage un rabat de protection destiné à recouvrir un système de serrage.The invention will find application in bonding a protective flap to cover a clamping system.

Le collage des deux éléments de tige pourra être effectué dans une zone décaissée où l'un des deux éléments de tige présente un décaissement, par exemple sous la forme d'une zone de moins grande épaisseur.Bonding of the two rod elements may be performed in a disbursed zone where one of the two rod elements has a disbursement, for example in the form of a zone of smaller thickness.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit, ainsi qu'au vu des dessins annexés dans lesquels :

  • la figure 1 est une vue schématique en perspective avec arrachement d'un premier exemple de réalisation d'une chaussure de sport conforme aux enseignements de l'invention, la chaussure comportant un rabat de protection,
  • la figure 2 est une vue agrandie de l'arrachement de la figure 1 illustrant plus en détail la zone de collage,
  • la figure 3 est une vue similaire à celle de la figure 1 illustrant une variante de réalisation de l'assemblage du rabat de protection (lequel est par ailleurs illustré en position ouverte),
  • la figure 4 est une vue similaire à la figure 2, c'est-à-dire une vue agrandie de l'arrachement de la figure 1 illustrant plus en détail la variante de réalisation de la zone de collage du rabat sur la tige.
Other features and advantages of the invention will appear on reading the detailed description which follows, as well as in view of the appended drawings in which:
  • the figure 1 is a diagrammatic perspective view with cut away of a first embodiment of a sports shoe according to the teachings of the invention, the boot comprising a protective flap,
  • the figure 2 is an enlarged view of the tearing out of the figure 1 illustrating in more detail the bonding area,
  • the figure 3 is a view similar to that of the figure 1 illustrating an alternative embodiment of the assembly of the protective flap (which is also shown in the open position),
  • the figure 4 is a view similar to the figure 2 , that is to say, an enlarged view of the tearing off of the figure 1 illustrating in more detail the variant embodiment of the flap bonding zone on the rod.

On a représenté une chaussure de sport 10 qui comporte pour l'essentiel une semelle 12 sur laquelle une tige 14 est montée par toute technique connue. La tige 14 peut ainsi être montée sur la semelle par collage, par piquage, par surmoulage ou toute autre méthode.There is shown a sports shoe 10 which comprises essentially a sole 12 on which a rod 14 is mounted by any known technique. The rod 14 can thus be mounted on the sole by gluing, stitching, overmolding or any other method.

La tige 14 de la chaussure selon l'invention est essentiellement une tige souple, c'est-à-dire une tige formée de pièces principales en matériaux flexibles, ou relativement flexibles, tels que des tissus, des tissus enduits, du cuir et/ou des matières synthétiques utilisées en couches minces tels que des films,...etc. La tige peut toutefois comporter des éléments complémentaires relativement rigides pour assurer une mise en forme de la tige, et, par exemple, un bon maintien du pied, tels que des contreforts rigides ou semi-rigides, des embouts, des éléments de protection ou de décoration ou des renforts locaux.The stem 14 of the boot according to the invention is essentially a flexible rod, that is to say a rod formed of main parts made of flexible materials, or relatively flexible, such as fabrics, coated fabrics, leather and / or synthetic materials used in thin layers such as films, etc. The rod may, however, comprise relatively rigid complementary elements to ensure a shaping of the rod, and, for example, a good support of the foot, such as rigid or semi-rigid buttresses, end pieces, protective or protective elements. decoration or local reinforcements.

Par ailleurs, l'utilisation de matériaux qui sont par essence souples n'empêche pas de les utiliser dans une épaisseur ou sous une forme chimique telle qu'ils possèdent une certaine rigidité.Moreover, the use of materials that are essentially flexible does not prevent them from being used in a thickness or in a chemical form such that they have a certain rigidity.

Par opposition aux chaussures de ski alpin en matériaux rigides, une tige souple selon la présente invention s'adapte à la flexion du pied et/ou au déroulé de celui-ci lors de la pratique du sport.As opposed to alpine ski boots made of rigid materials, a flexible rod according to the present invention adapts to the flexion of the foot and / or the unwinding of the latter during the practice of the sport.

Selon l'invention, la tige 14 est formée extérieurement de plusieurs pièces, c'est-à-dire d'au moins deux pièces. Au moins deux de ces pièces sont assemblées par une zone de collage.According to the invention, the rod 14 is formed externally of several parts, that is to say at least two parts. At least two of these pieces are assembled by a bonding zone.

Par collage, on entend aussi bien un assemblage de deux pièces par un matériau adhésif interposé entre les deux pièces, qu'un collage par soudage dans lequel les deux matériaux sont assemblés directement l'un à l'autre sous l'effet d'un apport local de chaleur ou sous l'effet de vibrations, par exemple un collage par hautes fréquences ou par ultrasons. Dans le premier cas, le matériau utilisable pourra être une colle liquide ou pâteuse, un ciment, ou un ruban thermofusible. Dans le second cas, parfois appelé liaison par soudage, il n'y a pas d'apport de matière entre les deux pièces à assembler.Bonding means both an assembly of two parts by an adhesive material interposed between the two parts, a welding bonding in which the two materials are assembled directly to one another under the effect of a local supply of heat or under the effect of vibration, for example a high frequency bonding or ultrasound. In the first case, the usable material may be a liquid or pasty adhesive, a cement, or a hot melt tape. In the second case, sometimes called connection by welding, there is no supply of material between the two parts to be assembled.

De préférence, la zone de collage sera continue pour des raisons de meilleure résistance mécanique, de meilleur aspect esthétique, et pour des raisons de meilleure imperméabilité.Preferably, the bonding zone will be continuous for reasons of better mechanical strength, better aesthetic appearance, and for reasons of better impermeability.

Dans les deux exemples illustrés aux figures 1 à 4, la chaussure de sport est une chaussure de ski de fond 10 dont la semelle 12 comporte des moyens d'accrochage 16 destinés à coopérer avec une fixation de ski de fond. Les variantes des figures 1 et 3 ne diffèrent que par le mode de réalisation de l'assemblage collé.In the two examples illustrated in Figures 1 to 4 , the sports shoe is a cross-country ski boot 10 whose sole 12 comprises attachment means 16 intended to cooperate with a cross-country ski binding. Variants of figures 1 and 3 differ only in the embodiment of the glued assembly.

Comme on peut le voir à la figure 3, la tige de la chaussure illustrée comporte une claque externe 15 qui couvre sensiblement l'avant pied et qui s'étend vers l'arrière le long de la semelle, sensiblement jusqu'au talon. Elle comporte aussi un système de serrage, en l'occurrence un système de serrage par laçage 20, destinés à rapprocher deux quartiers 22 de la tige séparés par une fente longitudinale 24 qui s'étend dans la zone de cou de pied. Les quartiers 22 peuvent être réalisés d'une pièce avec la claque 15, ou réalisés sous la forme de pièces séparées. Dans ce premier type de chaussures, la tige 14 comporte encore un rabat de protection 26 qui, dans une position ouverte (cf. figure 3), donne accès_au laçage, et dans une position fermée (cf. figure 1), recouvre les moyens de serrage 20 et la fente longitudinale 24.As can be seen at figure 3 , the upper of the shoe shown has an outer slug 15 which substantially covers the forefoot and which extends rearwardly along the sole, substantially to the heel. It also comprises a clamping system, in this case a lacing clamping system 20, intended to bring two quarters 22 of the rod separated by a longitudinal slot 24 which extends in the area of the instep. The quarters 22 may be made in one piece with the slap 15, or made in the form of separate parts. In this first type of shoe, the rod 14 further comprises a protective flap 26 which, in an open position (cf. figure 3 ), gives access to the lacing, and in a closed position (cf. figure 1 ), covers the clamping means 20 and the longitudinal slot 24.

Ce rabat de protection 26 est constitué d'une pièce de matériau souple qui recouvre la portion de la tige 14 correspondant à la partie supérieure du pied allant de l'arrière des orteils jusqu'à la cheville. Le rabat 26 comporte donc deux bords longitudinaux interne et externe 17, et un bord avant 32 qui sont assemblés à la claque 15 par collage. Les bords longitudinaux 17 du rabat 26 s'étendent le long des côtés du cou de pied de la chaussure, et le bord avant 32 s'étend sensiblement transversalement au travers d'une zone correspondant à la zone de flexion métatarso-phalangienne de la chaussure. Le bord arrière du rabat 26 est libre, et le rabat 26 comporte une fermeture à glissière 28 qui débouche dans le bord arrière et qui délimite dans le rabat deux volets susceptibles de s'écarter l'un de l'autre lorsque la glissière 28 est ouverte pour donner accès au laçage. Le rabat 26 est de préférence réalisé en un matériau sensiblement imperméable, par exemple un tissu enduit ou une feuille de PVC.This protective flap 26 consists of a piece of flexible material which covers the portion of the rod 14 corresponding to the upper part of the foot from the back of the toes to the ankle. The flap 26 thus has two longitudinal inner and outer edges 17 and a front edge 32 which are joined to the slab 15 by gluing. The longitudinal edges 17 of the flap 26 extend along the sides of the instep of the shoe, and the front edge 32 extends substantially transversely through an area corresponding to the metatarsophalangeal flexion zone of the shoe. . The rear edge of the flap 26 is free, and the flap 26 has a zipper 28 which opens into the rear edge and which defines in the flap two flaps that can move away from one another when the slide 28 is open to give access to the lacing. The flap 26 is preferably made of a substantially impervious material, for example a coated fabric or a PVC sheet.

Selon l'invention, le rabat 26 est assemblé à la claque 15 par une zone de collage 18 qui, de préférence, s'étend en continu sur toute la longueur des bords, longitudinaux 17 et transversal 32, du rabat.According to the invention, the flap 26 is assembled to the slab 15 by a bonding zone 18 which preferably extends continuously over the entire length of the longitudinal, 17 and transverse edges 32 of the flap.

Sur la figure 2, on a illustré de manière schématique une manière de réaliser ce collage faisant appel ici à une couche de colle 30 répartie le long de la zone de collage. Dans ce cas, on peut voir d'une part que le bord du rabat 26 et la claque 15 se chevauchent dans la zone de collage 18, le rabat étant agencé au-dessus de la claque. Par ailleurs, le bord du rabat 26 est paré, c'est-à-dire qu'il est coupé en biseau pour diminuer graduellement son épaisseur au fur et à mesure que l'on s'approche du bord. De préférence, c'est la face inférieure du rabat 26 qui est ainsi biseautée. De la sorte, après l'assemblage, on ne perçoit pas, ou quasiment pas, de surépaisseur au niveau de la limite entre le rabat et la claque.On the figure 2 schematically illustrated a way to achieve this bonding here using an adhesive layer 30 distributed along the bonding area. In this case, it can be seen on the one hand that the edge of the flap 26 and the slap 15 overlap in the zone of collage 18, the flap being arranged above the slap. Furthermore, the edge of the flap 26 is trimmed, that is to say it is cut bevel to gradually reduce its thickness as one approaches the edge. Preferably, it is the underside of the flap 26 which is thus beveled. In this way, after assembly, there is no perceived, or almost no, extra thickness at the boundary between the flap and the slap.

Dans cet exemple de réalisation, l'assemblage est réalisé grâce à une colle classique. Il peut ainsi s'agir d'une colle à base PU ; par exemple une colle bi-composants polymérisable du type de celles utilisées pour l'assemblage tige/semelle. Cette colle est déposée par exemple manuellement au pinceau sur les zones de collage, et l'assemblage et réalisé éventuellement sous presse pour assurer une bonne adhésion.In this embodiment, the assembly is achieved by means of a conventional glue. It can thus be a PU-based glue; for example a polymerizable two-component adhesive of the type used for the assembly rod / sole. This adhesive is deposited for example manually by brush on the bonding areas, and the assembly and possibly carried out in press to ensure good adhesion.

Sur la figure 4, on a illustré une variante dans laquelle l'une au moins des deux pièces qui sont assemblées par collage comporte, dans la zone de collage 18, une zone formant un lamage, c'est-à-dire dont surface présente un décaissement. Ce lamage peut être une simple déformation locale, une zone de moindre épaisseur, ou encore une zone ayant subi une compression locale pour en diminuer l'épaisseur, avec le résultat supplémentaire d'une densification locale de la matière. Cette compression est généralement obtenue par des procédés associant pression et chaleur, par exemple par marquage par hautes fréquences.On the figure 4 a variant is illustrated in which at least one of the two parts which are assembled by gluing comprises, in the gluing area 18, a zone forming a counterbore, that is to say whose surface has a disbursement. This counterbore may be a simple local deformation, a zone of lesser thickness, or a zone having undergone local compression to reduce the thickness, with the additional result of a local densification of the material. This compression is generally obtained by methods combining pressure and heat, for example by marking with high frequencies.

Ainsi, dans l'exemple illustré, le bord de la claque 15 présente une zone comprimée d'épaisseur réduite qui s'étend sur toute la zone d'assemblage 18. La face supérieure de la claque 15 présente donc un décaissement marquée par un rebord 32, le décaissement correspondant à une zone d'épaisseur « e2 » inférieure à l'épaisseur « e1 » du reste de la claque. Le bord du rabat 26, lequel peut être paré ou non, chevauche donc ce bord décaissé de la claque, toujours avec interposition de la colle 30. Comme on le voit sur la figure, le décaissement de la claque permet de réduire la surépaisseur de l'assemblage collé, permettant au bord du rabat d'être presque affleurant au niveau de la face supérieure de la claque au delà du rebord 32. Bien entendu on pourrait prévoir que chacune des faces en contact des deux pièces assemblées par collage soient décaissées dans leur zone de chevauchement, ce qui réduirait encore toute surépaisseur. Avantageusement, le décaissement permet de protéger le chant de la pièce qui se trouve au-dessus dans le chevauchement (en l'occurrence le chant du rabat 36), limitant ainsi le risque de décollement par arrachement et pelage. De plus, le rebord 32 permet de contenir la colle au cas où celle-ci fluerait vers l'extérieur lorsque l'assemblage est mis sous pression pour assurer le collage, limitant le caractère inesthétique de tout débordement de colle. D'ailleurs, pour le cas où ce débordement de colle aurait lieu, au delà de la zone de chevauchement, le rebord 32 forcerait la colle à remonter au contact du chant du bord du rabat 26, noyant ce chant dans la colle. Le chant se trouverait alors renforcé par un léger excès de colle, évitant par exemple tout risque d'effilochage du chant.Thus, in the example shown, the edge of the slug 15 has a compressed area of reduced thickness that extends over the entire assembly area 18. The upper face of the slug 15 thus has a disbursement marked by a rim 32, the disbursement corresponding to a zone of thickness "e2" less than the thickness "e1" of the rest of the slap. The edge of the flap 26, which can be trimmed or not, therefore overlaps the disbursed edge of the slam, always with the interposition of the glue 30. As seen in the figure, the disbursement of the slap reduces the extra thickness of the slab. bonded assembly, allowing the edge of the flap to be almost flush with the level of the upper face of the slap beyond the flange 32. Of course one could predict that each of the faces in contact with the two pieces assembled by gluing are disbursed in their overlap area, which would further reduce any extra thickness. Advantageously, the disbursement makes it possible to protect the edge of the piece which is above it in the overlap (in this case the edge of the flap 36), thus limiting the risk of peeling by peeling and peeling. In addition, the flange 32 can contain the glue in case it would flow outwardly when the assembly is pressurized to ensure the bonding, limiting the unsightly nature of any overflow glue. Moreover, for the case where this glue overflow would take place beyond the overlap zone, the flange 32 force the glue back into contact with the edge of the edge of the flap 26, embedding this edge in the glue. The song would then be reinforced by a slight excess of glue, avoiding for example any risk of fraying of the song.

Avantageusement, la fermeture à glissière 28 est elle aussi assemblée au rabat 26 par collage. Pour cela, on prévoit dans le rabat une découpe rectangulaire qui s'étend par exemple parallèlement à un bord longitudinal 17 du rabat, et qui débouche dans le bord arrière du rabat. La fermeture à glissière, qui comporte deux rubans (dont chacun est porteur d'une série de dents), est collée par les bords extérieurs des rubans contre la face inférieure du rabat, le long des bords de la fenêtre.Advantageously, the zipper 28 is also assembled to the flap 26 by gluing. For this, there is provided in the flap a rectangular cut which extends for example parallel to a longitudinal edge 17 of the flap, and which opens into the rear edge of the flap. The zipper, which has two ribbons (each carrying a series of teeth), is adhered by the outer edges of the ribbons against the underside of the flap, along the edges of the window.

Grâce à cette construction collée on peut voir que la liaison ne pourra pas être affectée par frottements et autres agressions externes, ce qui en augmente la durée de vie. Cela est notamment important pour les zones de liaison qui sont situées dans la partie basse de la chaussure, c'est-à-dire la partie située en dessous de la cheville de l'utilisateur, et encore plus particulièrement dans la zone de flexion métatarsophalangienne et dans la zone de laçage.Thanks to this bonded construction it can be seen that the connection can not be affected by friction and other external aggressions, which increases the service life. This is particularly important for the binding areas that are located in the lower part of the shoe, that is to say the part located below the user's ankle, and even more particularly in the metatarsophalangeal flexion zone. and in the lacing area.

Bien entendu, un tel assemblage par collage est totalement imperméable, résistant à la pénétration de l'humidité dans la chaussure, humidité provenant de la pluie ou de la neige.Of course, such a collage assembly is completely impervious, resistant to the penetration of moisture into the shoe, moisture from rain or snow.

L'assemblage par collage est particulièrement intéressant pour la jonction des pièces de la tige qui sont agencées sur l'extérieur de la tige, et qui sont donc à la fois visibles, sujettes au contact direct avec de l'eau, de l'humidité ou de la neige, et sujettes aux frottements. Un tel assemblage est donc particulièrement intéressant pour un rabat de protection, mais il pourra aussi être utilisé pour d'autres pièces de la tige, comme cela sera en vu en liaison avec les autres modes de réalisations. En effet l'assemblage par collage supprime l'existence de coutures apparentes particulièrement fragiles vis-à-vis de l'abrasion, frottement et supprime donc le risque de rupture desdites coutures. L'assemblage par collage procure également une esthétique très particulière par l'absence de toute couture apparente.The bonding assembly is particularly interesting for the junction of the parts of the rod which are arranged on the outside of the stem, and which are therefore both visible, subject to direct contact with water, moisture or snow, and subject to friction. Such an assembly is therefore particularly advantageous for a protective flap, but it can also be used for other parts of the rod, as will be seen in connection with the other embodiments. In fact the assembly by gluing removes the existence of apparent seams particularly fragile vis-à-vis the abrasion, friction and thus eliminates the risk of rupture of said seams. Gluing assembly also provides a very particular aesthetic through the absence of any apparent seams.

Dans le mode de réalisation illustré, les matériaux des deux pièces de la tige qui sont assemblées l'une à l'autre par collage sont identiques et du même ordre d'épaisseur.In the illustrated embodiment, the materials of the two parts of the rod which are assembled to one another by gluing are identical and of the same order of thickness.

Eventuellement, on peut prévoir que pour l'assemblage des deux pièces considérées, la zone de collage soit complétée par d'autres moyens d'assemblage. On sait en effet que les techniques de collages sont très performantes en termes de résistance aux contraintes de cisaillement. En revanche, elles peuvent être moins résistantes aux contraintes d'arrachage ou de pelage. Si une des parties de la zone de liaison des deux pièces est particulièrement sujette à de telles contraintes, on pourra choisir de remplacer ou de compléter, dans cette zone, l'assemblage par collage par un autre type d'assemblage, par exemple par piquage. Dans l'exemple illustré, on pourra prévoir que, au niveau des extrémités arrière des bords longitudinaux 17 du rabat, la zone de collage soit renforcée par du piquage.Optionally, it can be provided that for the assembly of the two parts considered, the bonding area is completed by other assembly means. It is known that the bonding techniques are very efficient in terms of resistance to shear stresses. On the other hand, they may be less resistant to pulling or peeling stresses. If one of the parts of the connecting zone of the two parts is particularly subject to such constraints, it will be possible to choose to replace or complete, in this zone, the assembly by gluing by another type of assembly, for example by stitching. . In the illustrated example, it can be provided that, at the rear ends of the longitudinal edges 17 of the flap, the bonding zone is reinforced by stitching.

Bien entendu la présente invention n'est pas limitée aux seuls modes de réalisation décrits ci-avant à titre d'exemples non limitatifs, mais en englobe tous les modes de réalisation similaires ou équivalents. Notamment, les aspects particuliers de chacun des modes de réalisation décrits pourront être transposé aux autres modes de réalisation, avec les avantages afférents.Of course, the present invention is not limited to the embodiments described above by way of non-limiting examples, but encompasses all similar or equivalent embodiments. In particular, the particular aspects of each of the embodiments described may be transposed to the other embodiments, with the corresponding advantages.
