Definitions

  • the slightest lateral sliding of the edges of the envelope of the liner during skiing or during the booting generates at the lateral place of their superposition an internal bead more or less projecting depending on whether the sliding is important, and thus creates painful compression points for the skier.
  • a second drawback lies in the fact that the boot is in the rest state in the open position; in fact, as soon as the means for tightening the upper are released, said upper is urged to open completely under the pushing effect of the liner which tends to return to its initial position.
  • This arrangement therefore makes it necessary, on the one hand, to use closing elements to ensure the wrapping of the foot during putting on, and on the other hand, to provide elements or means for holding the rod of the shoe in a relaxed position, therefore not open, to allow walking for example.

  • Another problem that the invention proposes to solve is that of allowing easy customization or adaptability of at least one of the support wedges of the liner cooperating with the lower leg of the skier depending on the nature of the latter, morphology , strength, weight, ski technique, etc ..., and this without taking into account during manufacture, but rather during the acquisition of the shoe equipped with such a liner by the skier.

  • the liner is characterized by the fact that a relatively rigid, or even semi-flexible, reinforcement is attached to the outer wall of the footwear envelope, and by the fact that at least one support wedge and section comfort in shape of gutter, independent of the footwear envelope, and connected to this frame by at least one of its lateral wings by means of at least one advantageously removable sliding link, is arranged opposite the zone of high extensibility of the footwear envelope. It follows from this structural characteristic that the elastic zone and the wedge, while being independent, are capable of cooperating closely with one another, in particular when the shoe is closed.

  • such a construction avoids specifically providing the liner with closing or holding means to ensure from the fitting on a good wrapping of the foot and the lower leg, at least sufficient to allow walking shoe open for example, because it is the expandable zone which performs this function.

The perception of the tightening force on the foot and / or the lower leg is therefore correlated with the tightening force applied to the shell when the shoe is closed.

Description

La présente invention est relative à un chausson de confort disposé à l'intérieur d'une coque de chaussure de sport, telle qu'une chaussure de ski, et concerne en particulier un chausson obtenu selon une structure d'un seul tenant chaussant le pied et le bas de jambe du porteur du chausson en s'étendant jusqu'à la bordure supérieure de la tige de la chaussure.The present invention relates to a comfort liner disposed inside a shell of a sports boot, such as a ski boot, and relates in particular to a liner obtained according to a structure in one piece fitting the foot and the lower leg of the shoe liner extending to the upper edge of the upper of the shoe.

Les chaussons connus de ce genre se classent approximativement en deux grandes catégories :

  • une première catégorie qui concerne les chaussons conçus avec une enveloppe chaussante comportant une ouverture d'introduction du pied fermée par un rabat ou une languette,
  • une deuxième catégorie qui concerne les chaussons dont l'enveloppe chaussante, d'une part, couvre uniformément et sans discontinuité le pied et le bas de jambe, et d'autre part, comporte au moins une zone extensible qui s'étend lorsque l'on rentre le pied dans le chausson, et qui se resserre ensuite sur le bas de jambe du skieur.
Known slippers of this kind fall roughly into two main categories:
  • a first category which relates to slippers designed with a footwear envelope comprising an opening for introducing the foot closed by a flap or a tongue,
  • a second category which relates to slippers, the casing of which, on the one hand, covers the foot and the lower leg uniformly and without discontinuity, and on the other hand, comprises at least one extensible zone which extends when the the foot is tucked into the boot, which then tightens on the skier's lower leg.

Pour la première catégorie de chaussons, on peut citer à titre d'exemple les brevets FR 2 368 239 et EP 066 133. Dans le brevet FR 2 368 239 l'ouverture d'introduction est obtenue par la réalisation de fentes disposées latéralement le long de la zone recouvrant le bas de jambe du skieur. Ainsi, le chausson présente une partie antérieure enveloppant le pied et l'avant du bas de jambe, et une partie postérieure en forme de languette enveloppant le talon et l'arrière dudit bas de jambe. Afin de faciliter le chaussage, le chausson se présente, à l'état de repos, en position ouverte. Une telle structure présente un premier inconvénient dû à la superposttion des bords de l'enveloppe du chausson au niveau des fentes latérales, amplifié par ailleurs par la forme biseautée donnée auxdits bords de l'enveloppe et par la disposition de membranes pliables les reliant. En effet, par cette disposition le moindre glissement latéral des bords de l'enveloppe du chausson au cours de la pratique du ski ou lors du chaussage génère à l'endroit latéral de leur superposition un bourrelet interne plus ou moins en saillie selon que le glissement est important, et crée ainsi des points de compression douloureux pour le skieur. Un deuxième inconvénient réside dans le fait que le chausson se présente à l'état de repos en position ouverte ; en effet, dès que les moyens de serrage de la tige sont libérés, ladite tige est sollicitée à s'ouvrir complètement sous l'effet de poussée du chausson qui tend à revenir dans sa position initiale. Cette disposition rend donc nécessaire, d'une part, de mettre en oeuvre des éléments de fermeture pour assurer l'enveloppement du pied lors du chaussage, et d'autre part, de prévoir des éléments ou des moyens de maintien de la tige de la chaussure dans une position de relâchement, donc non ouverte, pour permettre la marche par exemple.For the first category of booties, mention may be made, for example, of patents FR 2 368 239 and EP 066 133. In patent FR 2 368 239 the insertion opening is obtained by making slots arranged laterally along of the area covering the skier's lower leg. Thus, the liner has an anterior part enveloping the foot and the front of the lower leg, and a rear tongue-shaped part enveloping the heel and the rear of said lower leg. In order to facilitate the fitting, the boot is, in the rest state, in the open position. Such a structure has a first drawback due to the superposition of the edges of the envelope of the liner at the level of the lateral slits, further amplified by the bevelled shape given to said edges of the envelope and by the arrangement of foldable membranes connecting them. In fact, by this arrangement, the slightest lateral sliding of the edges of the envelope of the liner during skiing or during the booting generates at the lateral place of their superposition an internal bead more or less projecting depending on whether the sliding is important, and thus creates painful compression points for the skier. A second drawback lies in the fact that the boot is in the rest state in the open position; in fact, as soon as the means for tightening the upper are released, said upper is urged to open completely under the pushing effect of the liner which tends to return to its initial position. This arrangement therefore makes it necessary, on the one hand, to use closing elements to ensure the wrapping of the foot during putting on, and on the other hand, to provide elements or means for holding the rod of the shoe in a relaxed position, therefore not open, to allow walking for example.

Dans le brevet EP 066 133, le chausson décrit comporte une enveloppe chaussante obtenue d'un seul tenant et une ouverture d'introduction du pied consistant en une seule fente réalisée dans la partie postérieure du chausson, laquelle fente est délimitée par une paire de rabats agencés de manière à se chevaucher. Un système de fermeture est associé aux rabats pour assurer l'enveloppement du chausson sur le pied et le bas de jambe du skieur. Du fait de la superposition des rabats, un tel chausson présente le même inconvénient que celui du chausson FR 2 368 239, c'est-à-dire que le glissement des rabats qui se produit pendant la pratique du ski génère une modification de la position du rabat interne, ou bourrelet ainsi constitué, vis-à-vis du bas de jambe du skieur, le long de sa partie postérieure. Un autre inconvénient concerne la mise en oeuvre des systèmes de fermeture associé aux rabats ; en effet, ce système, accessible seulement lorsque la tige de la chaussure est ouverte, présente l'inconvénient de procurer une sensation de tenue du bas de jambe qui n'est pas en relation avec le système de fermeture de la tige de la chaussure : par exemple, le serrage du chausson peut être relativement puissant et ainsi assurer un contact étroit sur le bas de jambe du skieur tandis que la fermeture de la tige de la chaussure peut laisser subsister un certain jeu entre l'enveloppe dudit chausson et la paroi interne de ladite tige.In patent EP 066 133, the boot described describes a footwear envelope obtained in a single piece and an opening for introducing the foot consisting of a single slot made in the rear part of the boot, which slot is delimited by a pair of flaps. arranged to overlap. A closure system is associated with the flaps to ensure the wrapping of the bootie on the skier's foot and lower leg. Due to the superimposition of the flaps, such a liner has the same drawback as that of the FR 2 368 239 liner, that is to say that the slipping of the flaps which occurs during skiing results in a modification of the position. of the internal flap, or bead thus formed, vis-à-vis the lower leg of the skier, along its part posterior. Another drawback concerns the implementation of the closure systems associated with the flaps; in fact, this system, accessible only when the upper of the shoe is open, has the drawback of providing a feeling of holding of the lower leg which is not related to the closure system of the upper of the shoe: for example, the tightening of the boot can be relatively powerful and thus ensure close contact on the lower leg of the skier while the closure of the upper of the boot can leave some play between the envelope of said boot and the inner wall of said rod.

Pour la deuxième catégorie de chaussons, les brevets FR 2 360 271 et IT 1 117 339, montrent des chaussons dont l'enveloppe chaussante couvre uniformément et sans discontinuité le pied et le bas de jambe du skieur. De tels chaussons présentent, par rapport aux chaussons précédents, l'avantage de ne pas comporter de chevauchement ou de superposition de rabats et/ou de languette.For the second category of slippers, the patents FR 2 360 271 and IT 1 117 339 show slippers whose casing covers uniformly and continuously the skier's foot and lower leg. Compared with previous slippers, such booties have the advantage of not overlapping or overlapping flaps and / or tabs.

Dans le cas du brevet FR 2 360 271, il s'agit d'un chausson interne dont la tige montante est fermée sur tout son pourtour, lequel possède une plus grande extensibilité circonférentielle que les autres parties du chausson.In the case of patent FR 2 360 271, it is an internal liner whose rising rod is closed over its entire periphery, which has greater circumferential extensibility than the other parts of the liner.

Pour cela, ladite paroi est divisée en lamelles qui s'étendent transversalement par rapport à la circonférence et qui sont attenantes alternativement, en accordéon.For this, said wall is divided into strips which extend transversely relative to the circumference and which are adjoining alternately, in accordion.

Ainsi, le chausson peut se dilater pour permettre le passage du pied, par déploiement des lamelles en accordéon formant en quelque sorte un soufflet.Thus, the liner can expand to allow the passage of the foot, by deployment of the accordion strips forming a sort of bellows.

Une telle conception présente néanmoins un certain nombre d'inconvénients car en étirant les lamelles on fait varier l'épaisseur de la paroi du chausson, et de plus on confère à celle-ci une souplesse pas forcément recherchée, notamment à la partie postérieure du chausson devant constituer un appui ferme contre la coque de la chaussure.Such a design nevertheless has a certain number of drawbacks because by stretching the lamellae the thickness of the wall of the boot is varied, and moreover it is given flexibility not necessarily sought after, in particular in the rear part of the boot to constitute a firm support against the shell of the shoe.

De plus, ce déploiement des lamelles procure un effet contradictoire en fonction de la corpulence du skieur. En effet, si ce dernier est de forte taille, il aura tendance à provoquer un grand étirement des lamelles en accordéon et donc d'amoindrir leur résistance, alors que dans ce cas il faudrait plutôt la renforcer et inversement. La qualité des appuis est donc directement influencée par les variations du périmètre du bas de jambe du skieur.In addition, this deployment of the blades provides a contradictory effect depending on the body size of the skier. Indeed, if the latter is large, it will tend to cause a large stretch of the accordion slats and therefore lessen their resistance, while in this case it should rather be reinforced and vice versa. The quality of the supports is therefore directly influenced by variations in the perimeter of the skier's lower leg.

Par ailleurs, une telle conception implique l'utilisation d'un matériau de même nature. Or, l'expérience a démontré qu'un chausson à la fois confortable et efficace dans la pratique du ski devrait permettre une prise d'appui arrière relativement ferme et un appui avant en flexion, selon un degré d'élasticité choisi en fonction du confort recherché.Furthermore, such a design involves the use of a material of the same kind. However, experience has shown that a boot that is both comfortable and effective in skiing should allow relatively firm rear support and front support in flexion, according to a degree of elasticity chosen according to comfort. research.

Dans l'exemple du brevet IT 1 117 339, le chausson interne est obtenu avec une tige montante fermée sur tout son pourtour et avec deux zones élastiques latérales destinées à lui conférer une plus grande élasticité pour permettre le passage du pied. La tige du chausson est dotée d'une cale postérieure et d'une cale antérieure séparées par les zones élastiques ces cales sont destinées, d'une part, à jouer un rôle d'ajustage du chaussant entre la surface interne de la coque de la chaussure et le bas de jambe du skieur, et d'autre part, à servir d'éléments d'appui et de confort pour le bas de jambe. Il ressort d'une telle structure que l'étirement des zones élastiques ne modifie pas les caractéristiques des cales, donc n'influence pas la qualité des appuis avant et arrière. Par contre, du fait que les cales sont indissociables des zones élastiques, il n'est pas possible de privilégier la surface de ces zones élastiques sans le faire au détriment de la surface des cales et donc du confort du skieur. Ainsi, quel que soit la solution choisie, la structure d'un tel chausson ne peut déboucher que sur un compromis entre la facilité de chaussage recherchée, qui exige une grande possibilité d'extensibilité donc de surface extensible, et le confort du skieur, qui exige de grandes surfaces d'appui et d'enveloppement. Par ailleurs, du fait de la liaison des cales avant et arrière aux zones élastiques, qui à l'usage sont promises à une usure voir à une distension rapide, la position relative desdites cales ne peut pas être stable pendant la pratique du ski et à l'usage dans le temps car il se produit un affaiblissement inhérent aux matériaux constitutifs de telles zones élastiques.In the example of patent IT 1,117,339, the inner boot is obtained with a rising upper closed around its entire periphery and with two lateral elastic zones intended to give it greater elasticity to allow the passage of the foot. The upper of the bootie is provided with a posterior wedge and an anterior wedge separated by the elastic zones. These wedges are intended, on the one hand, to play a role in adjusting the footwear between the internal surface of the shell of the shoe and the lower leg of the skier, and on the other hand, to serve as support and comfort elements for the lower leg. It emerges from such a structure that the stretching of the elastic zones does not modify the characteristics of the wedges, therefore does not influence the quality of the front and rear supports. On the other hand, because the wedges are inseparable from the elastic zones, it is not possible to favor the surface of these elastic zones without doing so to the detriment of the surface of the wedges and therefore of the comfort of the skier. Thus, whatever the solution chosen, the structure of such a liner can only lead to a compromise between the desired ease of fitting, which requires a large possibility of extensibility, therefore of extensible surface, and the comfort of the skier, which requires large support and wrapping surfaces. Furthermore, due to the connection of the front and rear cleats to the elastic zones, which in use are liable to wear or even to rapid distension, the relative position of said cleats cannot be stable during skiing and use over time because there is a weakening inherent in the materials constituting such elastic zones.

La présente invention vise à résoudre les problèmes des chaussons à structure d'un seul tenant du type de ceux exposés ci-avant, et a notamment pour but de :

  • permettre un chaussage-déchaussage aisé ne nécessitant pas d'intervention manuelle de la part du skieur autant pour le passage du pied que pour son enveloppement,
  • procurer sur le pied et le bas de jambe un enveloppement uniforme, sans discontinuité,
  • garantir une tenue du pied et/ou du bas de jambe qui soit interdépendante de l'action des moyens de fermeture de la chaussure,
  • assurer une qualité constante de la fermeté des appuis, et du confort, non influençable par les variations du périmètre du bas de jambe du skieur.
The present invention aims to solve the problems of slippers with a single-piece structure of the type of those set out above, and in particular aims to:
  • allow easy putting on and taking off without requiring manual intervention on the part of the skier as much for the passage of the foot as for its wrapping,
  • provide a uniform, non-discontinuous wrap over the foot and lower leg,
  • guaranteeing that the foot and / or the lower leg are held together which is interdependent on the action of the shoe closing means,
  • ensure a constant quality of the firmness of the supports, and of the comfort, not influenced by variations in the perimeter of the lower leg of the skier.

Un autre problème que l'invention se propose de résoudre est celui de permettre une personnalisation ou adaptabilité aisée d'au moins une des cales d'appui du chausson coopérant avec le bas de jambe du skieur en fonction de la nature de ce dernier, morphologie, force, poids, technique de ski, etc..., et ce, sans impliquer une prise en compte lors de la fabrication, mais plutôt lors de l'acquisition de la chaussure équipée d'un tel chausson par le skieur.Another problem that the invention proposes to solve is that of allowing easy customization or adaptability of at least one of the support wedges of the liner cooperating with the lower leg of the skier depending on the nature of the latter, morphology , strength, weight, ski technique, etc ..., and this without taking into account during manufacture, but rather during the acquisition of the shoe equipped with such a liner by the skier.

Pour atteindre ces buts, le chausson interne selon l'invention est interposé entre le bas de jambe et le pied d'un skieur et une coque de chaussure de sport telle qu'une chaussure de ski, et se présente sous la forme d'une structure d'un seul tenant intégrant d'une part, des moyens extensibles élastiquement destinés à faciliter le passage du pied au chaussage et au déchaussage, et d'autre part, des cales d'appui et de confort pour le bas de jambe du skieur. Le chausson comporte une empeigne et une tige, lesquelles enveloppent sans discontinuité le pied et le bas de jambe de sorte qu'elles constituent une enveloppe chaussante de confort, ou chaussette, délimitant le volume du chaussant de manière uniforme et sans discontinuité. Cette enveloppe est pourvue des moyens extensibles sur au moins une zone de la tige qui débouche sur le pourtour d'introduction du pied. Cette zone élastique est destinée à permettre un chaussage aisé sans intervention manuelle du skieur, c'est-à-dire que lors du passage du pied de ce dernier elle s'étire puis se resserre sur son bas de jambe. Le chausson se caractérise par le fait qu'une armature relativement rigide, voire semi-flexible, est rapportée sur la paroi extérieure de l'enveloppe chaussante, et par le fait qu'au moins une cale d'appui et de confort de section en forme de gouttière, indépendante de l'enveloppe chaussante, et reliée à cette armature par au moins une de ses ailes latérales à l'aide d'au moins une liaison coulissante avantageusement démontable, est disposée en vis-à-vis de la zone de grande extensibilité de l'enveloppe chaussante. Il résulte de cette caractéristique structurelle que la zone élastique et la cale, tout en étant indépendantes, sont aptes à coopérer étroitement entre elles, en particulier lors de la fermeture de la chaussure. A cet effet, la et/ou les liaisons coulissantes sont, d'une part, orientées approximativement en direction de la partie du pied ou du bas de jambe à tenir à l'aide de la cale d'appui, et d'autre part, sont dotées d'une liberté de déplacement en translation permettant d'écarter largement la cale d'appui pour le passage dans l'enveloppe chaussante du pied du skieur, puis son rapprochement contre celui-ci et/ou le bas de jambe lorsque la coque de la chaussure est refermée sur le chausson. Il va de soi que la coque de chaussure présente en vis-à-vis de la cale d'appui mobile au moins un élément de serrage déplaçable en direction de la cale, lors de la fermeture de la chaussure, et libre de reculer lors de l'ouverture de cette dernière. Ainsi, du fait que la cale d'appui est reliée de manière coulissante à l'armature relativement rigide du chausson, son positionnement reste constant tout en permettant un grand étirement de la zone extensible de l'enveloppe chaussante située en vis-à-vis. Par ailleurs, du fait qu'en position chaussure fermée la cale vient se plaquer contre la zone extensible et donc contre la partie du pied et/ou du bas de jambe du skieur, l'appui procuré est équivalent à celui qui serait obtenu selon une structure monobloc, c'est-à-dire qu'il n'est pas influencé par les variations de volume du pied ou du périmètre du bas de jambe du skieur. Encore, une telle construction évite de doter spécifiquement le chausson de moyens de fermeture ou de maintien pour assurer dès le chaussage un bon enveloppement du pied et du bas de jambe, au moins suffisant pour permettre la marche chaussure ouverte par exemple, car c'est la zone extensible qui assure cette fonction. Egalement, cette construction garantit une tenue du pied et/ou du bas de jambe interdépendante de l'action des moyens de fermeture de la chaussure, puisque c'est le serrage de la coque et/ou de la tige de celle-ci qui met les cales d'appui du chausson en pression contre lesdits pied et/ou bas de jambe. La perception de l'effort de serrage sur le pied et/ou le bas de jambe est donc en corrélation avec l'effort de serrage appliqué sur la coque lors de la fermeture de la chaussure.To achieve these goals, the inner boot according to the invention is interposed between the lower leg and the foot of a skier and a shell of a sports boot such as a ski boot, and is in the form of a structure in one piece integrating on the one hand, elastically extensible means intended to facilitate the passage of the foot to putting on and taking off, and on the other hand, support and comfort wedges for the lower leg of the skier . The liner has a vamp and a shank, which continuously envelop the foot and the lower leg so that they constitute a comfort footwear envelope, or sock, delimiting the volume of the footwear in a uniform and discontinuous manner. This envelope is provided with means that can be extended over at least one region of the upper which opens onto the periphery of introduction of the foot. This elastic zone is intended to allow an easy boot without manual intervention of the skier, that is to say that during the passage of the foot of the latter it stretches and then tightens on its lower leg. The liner is characterized by the fact that a relatively rigid, or even semi-flexible, reinforcement is attached to the outer wall of the footwear envelope, and by the fact that at least one support wedge and section comfort in shape of gutter, independent of the footwear envelope, and connected to this frame by at least one of its lateral wings by means of at least one advantageously removable sliding link, is arranged opposite the zone of high extensibility of the footwear envelope. It follows from this structural characteristic that the elastic zone and the wedge, while being independent, are capable of cooperating closely with one another, in particular when the shoe is closed. To this end, the and / or the sliding links are, on the one hand, oriented approximately in the direction of the part of the foot or of the lower leg to be held using the support wedge, and on the other hand , have a freedom of movement in translation allowing to widely spread the support wedge for the passage in the footwear envelope of the skier's foot, then its approximation against it and / or the lower leg when the shoe shell is closed on the liner. It goes without saying that the shoe shell has vis-à-vis the movable support wedge at least one clamping element movable in the direction of the wedge, when the shoe is closed, and free to move back when the opening of the latter. Thus, owing to the fact that the support wedge is slidably connected to the relatively rigid reinforcement of the liner, its positioning remains constant while allowing a great stretching of the extensible zone of the footwear envelope located opposite . Furthermore, the fact that in the closed shoe position the wedge is pressed against the extensible zone and therefore against the part of the skier's foot and / or lower leg, the support provided is equivalent to that which would be obtained according to a monobloc structure, that is to say it is not influenced by variations in foot volume or the perimeter of the skier's lower leg. Again, such a construction avoids specifically providing the liner with closing or holding means to ensure from the fitting on a good wrapping of the foot and the lower leg, at least sufficient to allow walking shoe open for example, because it is the expandable zone which performs this function. Also, this construction guarantees a holding of the foot and / or the lower leg interdependent on the action of the shoe closure means, since it is the tightening of the shell and / or of the upper thereof that puts the liner's support wedges in pressure against said foot and / or lower leg. The perception of the tightening force on the foot and / or the lower leg is therefore correlated with the tightening force applied to the shell when the shoe is closed.

Selon un mode de réalisation de l'invention, la cale d'appui reliée coulissante à l'armature du chausson est également réglable en position par rapport à la zone élastique extensible avec laquelle elle coopère, par exemple en hauteur s'il s'agit d'une zone extensible située sur la tige de l'enveloppe chaussante.According to one embodiment of the invention, the support wedge slidingly connected to the frame of the liner is also adjustable in position relative to the extensible elastic zone with which it cooperates, for example in height if it is an expandable zone located on the upper of the footwear envelope.

Il est bien entendu que la cale d'appui reliée coulissante à l'armature est libre de basculer et/ou pivoter autour de la liaison afin de s'adapter également en inclinaison à la zone du bas de jambe ou du pied située en vis-à-vis. A cet effet, la cale d'appui n'a pas d'autre liaison par articulation que celle la reliant à l'armature du chausson ; ainsi, sa base, ou extrémité inférieure, reste libre de débattre afin de dégager les zones de passage ou de proéminence du pied telles que celles du cou-de-pied et/ou du talon qui sont réalisées sur l'enveloppe chaussante, de préférence en un matériau extensible au moins pour les parties en vis-à-vis de la cale d'appui considérée.It is understood that the support wedge slidingly connected to the frame is free to tilt and / or pivot around the link in order to also adapt in inclination to the region of the lower leg or of the foot located opposite. opposite. For this purpose, the support wedge has no other articulation connection than that connecting it to the frame of the liner; thus, its base, or lower end, remains free to debate in order to clear the areas of passage or prominence of the foot such as those of the instep and / or the heel which are produced on the footwear, preferably in an extensible material at least for the parts facing the support wedge considered.

Selon une variante de réalisation, la cale d'appui du chausson peut être retenue sur l'enveloppe chaussante par une pièce élastique de très faible résistance afin que son extrémité inférieure reste toujours librement déplaçable en tous sens tout en étant sollicitée à rester centrée.According to an alternative embodiment, the liner support wedge can be retained on the footwear envelope by an elastic piece of very low resistance so that its lower end always remains freely movable in all directions while being urged to remain centered.

Il est évident que le chausson selon l'invention n'est pas limité à un type de chaussure de ski ; ainsi, dans le cas des chaussures dites à "ouverture par l'avant" ou "centrale", une zone extensible de l'enveloppe chaussante du chausson dotée d'une cale d'appui coulissante-pivotante est au moins réalisée sur la partie antérieure de ce dernier, sensiblement en correspondance de la partie antérieure du bas de jambe du skieur et du coude-pied de ce dernier.It is obvious that the boot according to the invention is not limited to one type of ski boot; thus, in the case of so-called "front opening" or "central" shoes, an expandable zone of the footwear envelope of the bootie provided with a sliding-pivoting support wedge is at least produced on the front part of the latter, substantially in correspondence with the front part of the lower leg of the skier and the elbow of the latter.

Inversement, dans le cas des chaussures dites "à entrée par l'arrière", une zone extensible de l'enveloppe chaussante avec une cale d'appui coulissante-pivotante est au moins réalisée dans la partie postérieure du chausson.Conversely, in the case of so-called "rear entry" shoes, an expandable zone of the footwear envelope with a sliding-pivoting support wedge is at least produced in the rear part of the bootie.

Selon un détail de réalisation de l'invention, l'armature relativement rigide rapportée sur l'extérieur de l'enveloppe chaussante du chausson présente des ouvertures et échancrures de dégagement sensiblement en correspondance des zones de passage des proéminences du pied et/ou du bas de jambe.According to a detail of embodiment of the invention, the relatively rigid reinforcement attached to the outside of the footwear envelope of the bootie has openings and notches of clearance substantially in correspondence of the zones of passage of the prominences of the foot and / or the bottom leg.

En association avec de telles ouvertures et/ou échancrures de dégagement obtenues sur l'armature, l'enveloppe chaussante est de préférence réalisée avec des zones élastiques s'étendant en correspondance et à l'intérieur de celles-ci. Egalement, les cales d'appui reliées à l'armature peuvent avantageusement être prévues avec une surface d'enveloppement qui ne couvre pas toute la surface de la ou des zones élastiques en vis-à-vis, et notamment qui ne s'étend pas sur les ouvertures de dégagement de l'armature.In association with such openings and / or relief notches obtained on the frame, the footwear envelope is preferably made with elastic zones extending in correspondence and inside thereof. Also, the support wedges connected to the frame may advantageously be provided with a wrapping surface which does not cover the entire surface of the elastic zone or zones facing each other, and in particular which does not extend on the armature clearance openings.

Avantageusement, du fait que le chausson dispose d'une armature relativement rigide, cette dernière peut être réalisée avec un moyen de retenue intervenant entre ladite armature et la coque de la chaussure par emboîtement élastique avec un moyen correspondant réalisé sur la paroi intérieure de celle-ci, afin de procurer une mise en place correcte du chausson dans la coque, et sa retenue lors de l'extraction du pied de la chaussure. Egalement, un autre moyen de retenue ou d'accrochage peut être prévu pour assurer la liaison et/ou la retenue d'une partie de la bordure supérieure de la tige du chausson avec celle de la coque de la chaussure, ce moyen étant ainsi susceptible d'être utilisé pour empêcher le glissement de l'enveloppe chaussante dans la chaussure lors de l'introduction du pied.Advantageously, because the liner has a relatively rigid frame, the latter can be produced with a retaining means intervening between said frame and the shell of the shoe by elastic interlocking with a corresponding means produced on the inner wall thereof. ci, in order to obtain a correct positioning of the liner in the shell, and its retention during the extraction of the foot from the shoe. Also, another means of retention or attachment may be provided to ensure the connection and / or the retention of a part of the upper edge of the upper of the bootie with that of the shell of the shoe, this means thus being susceptible to be used to prevent the sliding of the footwear envelope in the shoe when the foot is introduced.

Selon une autre variante de réalisation de l'invention, la cale d'appui et de confort située en vis-à-vis de la zone élastique correspondante est obtenue d'une pièce avec l'armature de l'enveloppe chaussante dont elle constitue un prolongement en forme de languette. Dans ce cas de construction, la languette s'étend sur une longueur telle qu'elle recouvre la zone élastique en vis-à-vis pour être reconnectée par son extrémité libre à l'armature du côté opposé à celui d'où elle est issue. Comme dans les exemples précédents, on dispose une liaison pivotante-coulissante à cette extrémité, cette liaison pouvant être éventuellement réalisée simplement au moyen d'une bande élastique. En effet, lorsque la cale d'appui est ainsi obtenue, son maintien en position par rapport à l'enveloppe chaussante est pratiquement garantie par la rigidité de l'armature, ce qui fait que son extrémité libre ne nécessite pas la mise en oeuvre d'une liaison rigide. Cette languette est évidemment rembourrée par un matériau de confort du côté correspondant à la partie du pied ou du bas de jambe avec laquelle elle est destinée à coopérer et constitue ainsi la cale d'appui.According to another alternative embodiment of the invention, the support and comfort wedge located opposite the corresponding elastic zone is obtained in one piece with the frame of the footwear envelope of which it constitutes a tongue-shaped extension. In this case of construction, the tongue extends over a length such that it covers the elastic zone opposite so as to be reconnected by its free end to the armature on the side opposite to that from which it originated. . As in the previous examples, there is a pivoting-sliding connection at this end, this connection possibly being able to be produced simply by means of an elastic band. Indeed, when the support wedge is thus obtained, its maintenance in position relative to the footwear envelope is practically guaranteed by the rigidity of the frame, which means that its free end does not require the implementation of 'a rigid connection. This tongue is obviously padded with a material of comfort on the side corresponding to the part of the foot or of the lower leg with which it is intended to cooperate and thus constitutes the support wedge.

L'invention sera mieux comprise en se reportant à la description qui suit en référence aux dessins schématiques annexés illustrant, à titre d'exemple non limitatif, plusieurs variantes de réalisation du chausson.The invention will be better understood by referring to the description which follows with reference to the appended schematic drawings illustrating, by way of nonlimiting example, several alternative embodiments of the boot.

La figure 1 représente, vu en perspective, un premier mode de réalisation d'un chausson selon l'invention dans lequel la cale d'appui avant se présente sous la forme d'une bande transversale horizontale s'étendant au-dessus de la zone du cou-de-pied, en position initiale correspondant à celle de la chaussure ouverte.Figure 1 shows, seen in perspective, a first embodiment of a liner according to the invention in which the front support wedge is in the form of a horizontal transverse band extending above the area of the instep, in the initial position corresponding to that of the open shoe.

La figure 2 montre le chausson de la figure 1 introduit dans la coque d'une chaussure de ski représentée en vue partiellement arrachée, et illustrant une chaussure à ouverture avant.Figure 2 shows the boot of Figure 1 introduced into the shell of a ski boot shown in partially broken away view, and illustrating a boot with front opening.

La figure 3 montre, également en perspective, un chausson équivalent à celui de la figure 1 mais dont la cale d'appui avant s'étend jusque sur la zone correspondant à celle du cou-de-pied.Figure 3 shows, also in perspective, a liner equivalent to that of Figure 1 but whose front support wedge extends to the area corresponding to that of the instep.

La figure 4 illustre, vu en perspective, un mode de réalisation du chausson avec une cale d'appui réglable en hauteur.Figure 4 illustrates, seen in perspective, an embodiment of the liner with a support wedge adjustable in height.

Les figures 5 et 6 montrent des détails de réalisation adaptés au chausson vus respectivement selon les lignes de coupe V-V et VI-VI.Figures 5 and 6 show details of construction adapted to the liner seen respectively along the cutting lines V-V and VI-VI.

La figure 7 montre, en perspective, un chausson toujours conforme à l'invention dans lequel l'armature rapportée sur l'extérieur de l'enveloppe chaussante forme, vue dans le plan horizontal tel que selon la coupe IIX-IIX, une languette transversale se refermant par recouvrement et représentée en figure 8.FIG. 7 shows, in perspective, a boot still in accordance with the invention in which the reinforcement attached to the outside of the footwear envelope forms, seen in the horizontal plane as in section IIX-IIX, a transverse tongue closing by overlap and shown in Figure 8.

La figure 9 illustre, vu en perspective arrière, un chausson selon l'invention dont la cale d'appui mobile coopérant avec la zone de grande extensibilité est réalisée dans la partie postérieure de ce dernier, cette réalisation de chausson correspondant avantageusement à son emploi dans des chaussures dites "à entrée par l'arrière".FIG. 9 illustrates, seen in rear perspective, a liner according to the invention, the movable support wedge cooperating with the zone of great extensibility is produced in the rear part of the latter, this embodiment of liner advantageously corresponding to its use in so-called "rear entry" shoes.

La figure 10 représente, schématiquement, un type de chaussure à entrée par l'arrière muni du chausson de la figure 9.FIG. 10 schematically represents a type of shoe with rear entry provided with the slipper of FIG. 9.

Le chausson interne 1 selon l'invention, figures 1 et 2, est destiné à être introduit dans une coque 2 de chaussure de ski qui, dans cet exemple, est du type à "entrée par l'avant" et/ou "centrale" ; dans une telle chaussure, la partie antérieure supérieure de la coque 2 est munie de rabats 4,4', que l'on écarte pour laisser passer le pied et que l'on resserre au moyen de dispositifs de tension 5 pour fermer la chaussure. Par l'action de tirage des dispositifs 5 sur les rabats 4, 4', ces derniers se rapprochent plus ou moins en direction du chausson et par là-même en direction du pied du skieur. Ce chausson 1, de structure d'un seul tenant, présente, d'une part, une enveloppe chaussante 6 qui comporte une empeigne 7 et une tige 8 dont une zone élastique 9 est destinée à faciliter le passage du pied au chaussage-déchaussage, et d'autre part, au moins une cale d'appui et de confort 10, 11, 12, coopérant avec le pied et/ou le bas de jambe du skieur. Selon une caractéristique, le chausson est pourvu d'une armature 13 rapportée sur la paroi extérieure de l'enveloppe chaussante 6, et une cale d'appui et de confort 11 est rendue indépendante de l'enveloppe chaussante 6. Cette cale d'appui 11, de section sensiblement en forme de gouttière, est disposée en vis-à-vis de la zone élastique 9, et est reliée par chacune de ses ailes 11', 11'', à chacun des côtés de l'armature à l'aide d'une liaison 16 pivotante et coulissante, par coopération avec une lumière 35 orientée approximativement en direction du bas de jambe à tenir. Par ailleurs, chaque liaison pivotante 16 est prévue pour pouvoir se déplacer en translation 17 sur une certaine longueur afin d'écarter largement la cale d'appui 11, et ne pas entraver ou empêcher l'extension maximum de la zone élastique 9 lors du passage du pied du skieur dans l'enveloppe chaussante 6. Ainsi, lorsque le pied a été introduit dans le chausson 1 et que la tige de la coque 2 est fermée, la mise sous tension des rabats 4 par les dispositifs de tension 5 provoque le resserrement de la tige de la coque 2 sur le chausson ; par voie de conséquence, les rabats 4, qui sont des éléments de serrage déplaçables, repoussent la cale d'appui 11 en direction de la zone élastique 9 sur laquelle elle vient en contact étroit. la cale 11 assure ainsi l'appui pour la partie du bas de jambe sous-jacente à ladite zone élastique en s'adaptant également en inclinaison grâce à la possibilité de pivotement procurée par les articulations 16.The inner boot 1 according to the invention, FIGS. 1 and 2, is intended to be introduced into a shell 2 of a ski boot which, in this example, is of the "front entry" and / or "central"type.; in such a shoe, the upper front part of the shell 2 is provided with flaps 4, 4 ', which are spread to let the foot pass and that are tightened by means of tensioning devices 5 to close the shoe. By the pulling action of the devices 5 on the flaps 4, 4 ', the latter more or less approach in the direction of the liner and thereby in the direction of the skier's foot. This liner 1, of a single-piece structure, has, on the one hand, a footwear envelope 6 which comprises a vamp 7 and a upper 8 of which an elastic zone 9 is intended to facilitate the passage of the foot to the boot-heaving shoe, and on the other hand, at least one support and comfort wedge 10, 11, 12, cooperating with the skier's foot and / or lower leg. According to one characteristic, the liner is provided with a frame 13 attached to the outer wall of the footwear envelope 6, and a support and comfort wedge 11 is made independent of the footwear envelope 6. This support wedge 11, of section substantially in the form of a gutter, is arranged opposite the elastic zone 9, and is connected by each of its wings 11 ′, 11 ″, to each of the sides of the frame. using a pivoting link 16 and sliding, by cooperation with a light 35 oriented approximately in the direction of the lower leg to be held. Furthermore, each pivoting link 16 is designed to be able to move in translation 17 over a certain length in order to widely separate the support wedge 11, and not to hinder or prevent the maximum extension of the elastic zone 9 during passage of the skier's foot in the footwear envelope 6. Thus, when the foot has been introduced into the liner 1 and the shell rod 2 is closed, the tensioning of the flaps 4 by the tensioning devices 5 causes the tightening the stem of the shell 2 on the liner; consequently, the flaps 4, which are displaceable clamping elements, push the support wedge 11 in the direction of the elastic zone 9 on which it comes into close contact. the wedge 11 thus provides support for the part of the lower leg underlying said elastic zone, also adapting in inclination thanks to the possibility of pivoting provided by the joints 16.

Selon un détail de réalisation, l'armature 13 est obtenue avec des ouvertures de dégagement 18 et 19 dans sa partie postérieure, l'une, 18, pour permettre le passage aisé du talon du skieur lors du chaussage-déchaussage, et l'autre, 19, pour le logement dudit talon dans l'enveloppe chaussante 6. Le chausson 1 étant du type destiné aux chaussures à entrée par l'avant et/ou centrale, l'armature 13 est également échancrée 20 dans sa partie antérieure pour laisser libre toute zone supérieure antérieure de l'enveloppe chaussante 6 qui s'étend à partir et au-dessus du cou-de-pied. Avantageusement, la et/ou les ouvertures de dégagement 18, 19, sont en correspondance des zones élastiques 14 réalisées sur l'enveloppe chaussante 6.According to a detail of embodiment, the frame 13 is obtained with clearance openings 18 and 19 in its rear part, one, 18, to allow easy passage of the heel of the skier during shoeing-heaving, and the other , 19, for the housing of said heel in the casing 6. The liner 1 being of the type intended for shoes with front and / or central entry, the frame 13 is also indented 20 in its front part to leave free any anterior upper zone of the footwear envelope 6 which extends from and above the instep. Advantageously, the and / or the clearance openings 18, 19 are in correspondence with the elastic zones 14 produced on the footwear envelope 6.

Dans cet exemple de la figure 1, le chausson 1 est pourvu d'une cale d'appui 11 qui ne recouvre pas la zone du cou-de-pied, mais peut aussi être prévu, comme illustré à la figure 3, avec une cale d'appui 21 qui enveloppe cette zone. Afin de permettre le débattement libre en tous sens de l'extrémité inférieure 22 de la cale 21 par rapport à l'enveloppe chaussante, soit la cale 21 n'a pas d'autres liaisons par articulation que celles 16 de ses ailes 21', 21'', situées de chaque côté du chausson, soit elle est dotée en plus d'une pièce de liaison 23 élastique en forme de bande et de très faible résistance. Ainsi, la cale d'appui 21, tout en étant sollicitée à rester centrée, est libre de se déplacer selon 17 et de s'adapter en fonction de la forme du cou-de-pied et/ou du bas de jambe.In this example of FIG. 1, the liner 1 is provided with a support wedge 11 which does not cover the area of the instep, but can also be provided, as illustrated in FIG. 3, with a wedge support 21 which envelops this zone. In order to allow free movement in all directions of the lower end 22 of the wedge 21 with respect to the casing, either the wedge 21 has no other articulation connections than those 16 of its wings 21 ′, 21 '', located on each side of the liner, or it is additionally provided with an elastic connecting piece 23 in the form of a strip and of very low resistance. Thus, the support wedge 21, while being urged to remain centered, is free to move along 17 and to adapt as a function of the shape of the instep and / or the lower leg.

Selon un autre mode de réalisation, figure 4, le chausson 30 muni d'une enveloppe chaussante 6 comporte une cale d'appui 31 dont la partie inférieure 32 est maintenue centrée sur l'enveloppe du chausson au moyen d'une pièce de liaison 23, en forme de bande disposée transversalement, et dont la partie supérieure 33 est réglable dans le sens de la hauteur sur une armature 34 ; pour cela, l'armature 34 est prévue avec plusieurs ouvertures allongées 35 susceptibles de recevoir respectivement une liaison 16, laquelle est de préférence prévue démontable. Ainsi, selon la hauteur de l'appui du bas de jambe désiré il suffit de positionner la cale 31 sur l'armature 34 au moyen des liaisons 16 de ses ailes 31', 31'', dans l'ouverture 35 correspondante qui détermine la direction 17 de déplacement possible de la cale 31, la liaison élastique 23 se déformant en conséquent.According to another embodiment, FIG. 4, the liner 30 provided with a footwear envelope 6 comprises a support wedge 31 whose lower part 32 is kept centered on the envelope of the liner by means of a connecting piece 23 , in the form of a strip arranged transversely, and the upper part 33 of which is adjustable in the direction of the height on a frame 34; for this, the frame 34 is provided with several elongated openings 35 capable of receiving respectively a connection 16, which is preferably provided removable. Thus, depending on the height of the support of the desired lower leg, it suffices to position the wedge 31 on the frame 34 by means of the connections 16 of its wings 31 ', 31' ', in the corresponding opening 35 which determines the direction 17 of possible movement of the wedge 31, the elastic connection 23 therefore deforming.

Des détails de construction sont également prévus pour ce qui concerne la coopération du chausson 30 avec la coque de la chaussure destinée à le recevoir. Par exemple, un moyen de retenue 36 tel qu'un ergot, figures 4 et 6, est réalisé sur l'extérieur de l'armature 34 dans la zone du talon en vis-à-vis de ce moyen de retenue 36 un moyen correspondant tel qu'une encoche ou une ouverture 37 est alors obtenu dans la paroi intérieure de la coque 2 de la chaussure, et la simple résistance latérale du chausson, schématiquement représentée par les flèches 38, assure l'emboîtement élastique lors de la mise en place du chausson et sa retenue lors de l'extraction du pied. Il est également prévu, figures 4 et 5, qu'un moyen d'accrochage 39 puisse assurer la liaison avec une partie de la bordure supérieure de la tige de la coque 2 de chaussure par chevauchement par exemple. Dans les exemples qui précèdent, les chaussons 1 et 30 présentent des cales d'appui 11, 21, totalement rapportées sur l'armature 13, 34, et ainsi disposent de deux liaisons 16 pivotantes-coulissantes pour tenir lesdites cales de manière relativement équilibrée et avec un positionnement qui reste constant. Selon une variante de réalisation représentée sur les figures 7 et 8, le chausson 40 muni d'une enveloppe chaussante 6 peut également être obtenu avec une cale d'appui 41 issue d'un prolongement 42 de l'armature 43. Dans ce cas de construction, la cale d'appui 41, en forme de languette transversale, s'étend sur une longueur permettant au moins le chevauchement partiel de son extrémité libre 44 ou aile avec le côté 45 de l'armature 43 opposé au côté 46 d'où elle est issue. L'armature 43 de l'enveloppe chaussante 6 étant relativement rigide, la cale d'appui 41 ainsi obtenue est fermement positionnée sur le côté 46 de l'armature et une seule liaison coulissante-pivotante 16, qui peut être remplacée par une bande de liaison élastique, connecte l'extrémité libre 44 sur l'autre côté 45 de ladite armature et permet son déplacement selon 17.Construction details are also provided with regard to the cooperation of the liner 30 with the shell of the shoe intended to receive it. For example, a retaining means 36 such as a lug, FIGS. 4 and 6, is produced on the outside of the frame 34 in the region of the heel opposite. from this retaining means 36 a corresponding means such as a notch or an opening 37 is then obtained in the inner wall of the shell 2 of the shoe, and the simple lateral resistance of the liner, schematically represented by the arrows 38, ensures the elastic fitting when fitting the liner and retaining it when extracting the foot. It is also provided, Figures 4 and 5, that a hooking means 39 can ensure the connection with a portion of the upper edge of the upper of the shoe shell 2 by overlapping for example. In the above examples, the liners 1 and 30 have support wedges 11, 21, completely attached to the frame 13, 34, and thus have two pivoting-sliding connections 16 for holding said wedges in a relatively balanced manner and with a positioning that remains constant. According to an alternative embodiment shown in FIGS. 7 and 8, the liner 40 provided with a footwear envelope 6 can also be obtained with a support wedge 41 resulting from an extension 42 of the frame 43. In this case of construction, the support wedge 41, in the form of a transverse tongue, extends over a length allowing at least partial overlapping of its free end 44 or wing with the side 45 of the frame 43 opposite the side 46 from which it came out. The frame 43 of the footwear envelope 6 being relatively rigid, the support wedge 41 thus obtained is firmly positioned on the side 46 of the frame and a single sliding-pivoting link 16, which can be replaced by a strip of elastic link, connects the free end 44 to the other side 45 of said frame and allows its displacement along 17.

Toujours conformément à l'invention, figure 9, le chausson 50 du type à entrée centrale et/ou par l'arrière, est doté d'une cale d'appui postérieure 51 qui coopère avec une zone élastique 59 d'une enveloppe chaussante 56. Comme dans les exemples précédents, la cale d'appui 51 est reliée à l'armature 53 par ses ailes 51', 51'', au moyen de liaisons 16 coulissantes dans des lumières 35, et les zones de passage et/ou de proéminence du pied sont dégagées, par exemple dans la zone du talon et dans la zone du cou-de-pied, par des ouvertures 19 et 20.Still in accordance with the invention, FIG. 9, the liner 50 of the central entry and / or rear entry type, is provided with a rear support wedge 51 which cooperates with an elastic zone 59 of a footwear envelope 56 As in the previous examples, the support wedge 51 is connected to the frame 53 by its wings 51 ', 51' ', by means of connections 16 sliding in slots 35, and the passage and / or prominence of the foot are released, for example in the heel area and in the instep area, by openings 19 and 20.

On retrouve donc une structure d'un seul tenant comprenant une enveloppe chaussante 56 avec une empeigne 57 et une tige 58, une armature 53, et au moins une cale d'appui 51 reliée par des liaisons coulissantes-pivotantes 16 à ladite armature, la cale d'appui 51 étant ainsi indépendante de ladite enveloppe chaussante 56.We therefore find a structure in one piece comprising a casing 56 with a vamp 57 and a rod 58, a frame 53, and at least one support wedge 51 connected by sliding-pivoting links 16 to said frame, the support wedge 51 thus being independent of said footwear envelope 56.

Comme précédemment, la cale d'appui 51 qui coopère avec la zone élastique 59 de passage du pied est mise en pression et/ou en appui contre la partie du pied et/ou du bas de jambe du skieur sous-jacente à ladite zone élastique au moyen d'un élément de serrage 54 de la coque 52 de chaussure tel qu'illustré schématiquement sur la figure 10. Cet élément de serrage 54 est constitué par le capot arrière de fermeture de la tige, et est pivotant sur la base de la coque 52 autour de liaisons tournantes 60. Ainsi, lors de sa fermeture par basculement selon 55, et verrouillage au moyen d'un dispositif de tension 5, la cale d'appui 51 est poussée et maintenue en position contre l'arrière du bas de jambe du skieur.As before, the support wedge 51 which cooperates with the elastic zone 59 for passage of the foot is pressurized and / or pressed against the part of the foot and / or the lower leg of the skier underlying said elastic zone. by means of a clamping element 54 of the shoe shell 52 as illustrated diagrammatically in FIG. 10. This clamping element 54 is constituted by the rear cover for closing the upper, and is pivotable on the base of the shell 52 around rotary connections 60. Thus, when it is closed by tilting along 55, and locked by means of a tensioning device 5, the support wedge 51 is pushed and held in position against the rear of the bottom of skier's leg.

Il est bien entendu que les enveloppes chaussantes 6, 56, des chaussons 1, 30, 40, 50, qui viennent d'être décrites à titre d'exemple présentent, en dehors de la et/ou des zones extensibles 9, 14, une paroi d'une épaisseur donnée destinée à jouer un rôle d'ajustage du chaussant entre la surface interne de la coque 2 de chaussure et le pied du skieur.It is understood that the footwear envelopes 6, 56, of the slippers 1, 30, 40, 50, which have just been described by way of example have, apart from the and / or the extensible zones 9, 14, a wall of a given thickness intended to play a role in adjusting the footwear between the internal surface of the boot shell 2 and the skier's foot.

Par ailleurs, le chausson selon l'invention peut être réalisé avec plus d'une cale d'appui qui soit indépendante de l'enveloppe chaussante et portée par l'armature. A titre d'exemple, non illustré, le chausson peut comporter à la fois une cale d'appui postérieure et une cale d'appui antérieure, l'armature étant alors obtenue avec des ouvertures et des zones de dégagement en correspondance desdites cales.Furthermore, the liner according to the invention can be produced with more than one support wedge which is independent of the footwear envelope and carried by the frame. By way of example, not shown, the liner may include both a posterior support wedge and an anterior support wedge, the reinforcement then being obtained with openings and clearance zones in correspondence with said wedges.

Enfin, les cales d'appui 11, 21, 31, 51, indépendantes de l'enveloppe chaussante 6, 56, peuvent être prévues amovibles de l'armature 13, 34, 53, en utilisant des liaisons 16 démontables. Ainsi, selon la morphologie du skieur et/ou de sa technique de ski il est aisé de procéder à l'interchangeabilité de la cale d'appui 11, 21, 31, 21, lors de la vente et/ou de l'acquisition de chaussure de ski, en montant une cale plus ou moins dure ou compressible par exemple.Finally, the support wedges 11, 21, 31, 51, independent of the footwear envelope 6, 56, can be provided removable from the frame 13, 34, 53, using removable links 16. Thus, depending on the morphology of the skier and / or his skiing technique, it is easy to interchangeably the support wedge 11, 21, 31, 21, during the sale and / or the acquisition of ski boot, by mounting a more or less hard or compressible wedge for example.
