Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne une talonnière de fixation de sécurité de type pour chaussure de sport, c'est-à-dire un dispositif destiné à maintenir de manière sécurisée l'arrière d'une chaussure sur une planche de glisse en exerçant une pression sur le talon de la chaussure tout en pressant vers l'avant l'ensemble de la chaussure contre un dispositif avant de butée, tout en assurant une libération automatique du talon de la chaussure en cas de chute avant sous l'effet de l'application par le talon sur la talonnière d'un effort de déclenchement supérieur à un seuil prédéterminé.The invention relates to a heel type safety fastening for sports shoes, that is to say a device for securely holding the back of a shoe on a gliding board by exerting a pressure on the heel of the shoe while pressing forward the entire shoe against a device before abutment, while ensuring an automatic release of the heel of the shoe in case of falling before under the effect of the application by the heel on the heel of a triggering force greater than a predetermined threshold.

Elle concerne également un dispositif de fixation comprenant une butée pour recevoir la partie avant d'une chaussure de ski et une telle talonnière, ainsi qu'une planche de glisse comme un ski sur laquelle est fixée une telle talonnière.It also relates to a fixing device comprising a stop for receiving the front portion of a ski boot and such a heel, and a gliding board such as a ski on which is fixed such a heel.

État de la techniqueState of the art

Les documents EP0893146 et EP1900400 décrivent à titre d'exemple une talonnière de l'état de la technique. Une telle talonnière comprend un corps mobile comprenant à son extrémité avant un agrippe-talon (ou mâchoire) pour agripper le talon d'une chaussure, pouvant occuper une position fermée et une position ouverte. Ce corps mobile comprend de plus une languette dans la partie inférieure de son extrémité avant, sur laquelle peut reposer le talon de la chaussure et qui est notamment utilisé lors du chaussage de la fixation puisque la chaussure vient appuyer sur cette languette pour faire pivoter le corps mobile d'une position ouverte dans laquelle le skieur peut retirer sa chaussure de la talonnière vers la position fermée de pratique du ski. Pour cette raison, cette languette est aussi souvent dénommée languette de chaussage. Une talonnière de ski intègre de plus un mécanisme de déclenchement dans sa partie arrière, qui permet de libérer automatiquement l'arrière de la chaussure en cas d'effort important, comme c'est le cas dans une chute du skieur vers l'avant, selon une approche standardisée.The documents EP0893146 and EP1900400 describe by way of example a heel of the state of the art. Such a heel comprises a movable body comprising at its front end a bead (or jaw) to grip the heel of a shoe, which can occupy a closed position and an open position. This movable body further comprises a tongue in the lower part of its front end, on which can rest the heel of the shoe and which is used in particular when donning the binding since the shoe is pressed on the tongue to rotate the body mobile of a open position in which the skier can remove his shoe from the heel to the closed position of skiing practice. For this reason, this tongue is also often referred to as a pull tab. A ski heel incorporates a trigger mechanism in its rear portion, which automatically releases the rear of the shoe in case of significant effort, as is the case in a skier's fall forward, according to a standardized approach.

Ces corps mobiles des talonnières de l'état de la technique se présentent en matériau plastique rigide, pour résister aux efforts importants qu'ils subissent durant la pratique du ski. Pour cela, les corps mobiles sont fabriqués par une étape d'injection plastique qui permet de former un ensemble monolithique comprenant notamment toute la partie antérieure, incluant l'agrippe-talon et la languette, et éventuellement toute une partie arrière formant un volume de réception du mécanisme de déclenchement. Ces solutions présentent l'avantage d'une fabrication facile et peu coûteuse. Toutefois, cette approche présente les inconvénients suivants :

  • l'ensemble du corps mobile, et en particulier l'agrippe-talon, est inévitablement dans un même matériau, non optimisé pour chaque partie particulière de ce corps mobile. Par exemple, la languette se trouve dans ce matériau qui n'est pas adapté à l'usure importante qu'elle subit au cours du temps et dont le coefficient de frottement n'est pas idéal pour la fonction de déclenchement ;
  • la languette présente une dimension fixe, dont l'épaisseur, et voire la longueur, n'est pas adaptée à tous les types de chaussures existants, comme les chaussures de randonnées, les chaussures de ski alpin pour adultes ou pour juniors, etc. ;
  • enfin, la forme de la languette doit être compatible avec le procédé d'injection, ce qui représente une limitation pour sa fabrication.
These mobile bodies of the heels of the state of the art are made of rigid plastic material, to withstand the significant efforts they undergo during the practice of skiing. For this purpose, the movable bodies are manufactured by a plastic injection step which makes it possible to form a monolithic assembly comprising in particular the entire anterior part, including the bead-grip and the tongue, and possibly a whole rear part forming a receiving volume. trigger mechanism. These solutions have the advantage of easy and inexpensive manufacture. However, this approach has the following drawbacks:
  • the entire movable body, and in particular the bead-grip, is inevitably in the same material, not optimized for each particular part of this movable body. For example, the tongue is in this material which is not adapted to the significant wear that it undergoes over time and whose coefficient of friction is not ideal for the tripping function;
  • the tongue has a fixed dimension, the thickness, and even the length, is not suitable for all types of existing shoes, such as hiking shoes, alpine ski boots for adults or juniors, etc. ;
  • finally, the shape of the tongue must be compatible with the injection process, which represents a limitation for its manufacture.

Il ressort des points précédents que la languette est en général trop courte ou pas assez épaisse, et n'offre pas une surface d'appui suffisante pour une chaussure, ce qui rend plus difficile le chaussage de la talonnière. De plus, elle présente une surface non optimale pour les phases de déclenchements du dispositif de fixation. Enfin, elle présente une usure rapide qui dégrade encore les inconvénients ci-dessus.It follows from the above points that the tongue is generally too short or not thick enough, and does not provide a sufficient support surface for a shoe, which makes it more difficult to wear the heel. In addition, it has a non-optimal surface for the triggering phases of the fixing device. Finally, it has a rapid wear which further degrades the above disadvantages.

FR81385E décrit une talonnière de fixation de sécurité d'une chaussure de sport sur une planche de glisse comprenant un agrippe-talon monté pivotant autotour d'une axe d'articulation et comprenant une languette s'étendant vers l'avant dans la partie antérieure inférieure de la talonnière où tout ou partie de la languette est formée par une pièce distincte de l'agrippe-talon. FR81385E discloses a heel guard for securing a sports boot to a gliding board comprising a heel catch pivotally pivoting about a hinge pin and having a tongue extending forwardly in the lower front portion of the heel where all or part of the tongue is formed by a separate part of the heel grip.

Le corps mobile 11, plus particulièrement visible sur les figures 3 et 4, renferme un mécanisme de déclenchement qui permet le passage automatique de la talonnière de la configuration de position fermée de pratique du ski, représentée sur la figure 4, à sa configuration en position ouverte, notamment représentée sur les figures 1 à 3, dans laquelle la chaussure de ski peut échapper à l'emprise de la talonnière, notamment de l'agrippe talon 10. Ce déclenchement est automatiquement mis en oeuvre dans le cas d'un effort de déclenchement transmis par le talon de la chaussure à l'agrippe talon 10 qui est supérieur à un seuil prédéterminé, par exemple en cas de chute du skieur vers l'avant. Le corps mobile 11 passe de la configuration fermée correspondant à la position fermée de la talonnière à la configuration ouverte correspondant à la position ouverte de la talonnière par un mouvement de pivotement par rapport au chariot, autour d'un axe d'articulation 14.The movable body 11, more particularly visible on the Figures 3 and 4 , encloses a triggering mechanism that allows the automatic passage of the heel of the closed ski practice position configuration, shown on the figure 4 , in its configuration in the open position, in particular represented on the Figures 1 to 3 , in which the ski boot can escape the grip of the heel, including the heel grip 10. This trigger is automatically set operates in the case of a triggering force transmitted by the heel of the shoe at the gripping heel 10 which is greater than a predetermined threshold, for example in the event of the skier's fall forward. The movable body 11 moves from the closed configuration corresponding to the closed position of the heel piece to the open configuration corresponding to the open position of the heel piece by a pivoting movement with respect to the carriage, about an articulation axis 14.

Pour mettre en oeuvre la fonction de déclenchement, le corps mobile 11 comprend différents éléments dans son volume intérieur, parmi lesquels un ressort de déclenchement 15 en appui contre la butée 16 dans la partie supérieure arrière du corps 11 et en appui sur un piston 17 à son autre extrémité. Ce piston 17 coopère avec une surface de déclenchement 18 prévue sur l'axe d'articulation, détaillé ci-après.To implement the tripping function, the movable body 11 comprises various elements in its interior volume, among which a release spring 15 bears against the abutment 16 in the upper rear part of the body 11 and bears on a piston 17 to its other end. This piston 17 cooperates with a triggering surface 18 provided on the hinge axis, detailed below.

Le seuil de déclenchement peut être modifié de manière connue en modifiant le degré de compression du ressort 15 par une vis de réglage 19 positionnée à l'extrémité arrière du corps mobile 11 et apte à déplacer la butée 16 intérieurement le long du corps mobile 11. Le corps mobile 11 présente ainsi la particularité d'être fermé dans sa partie inférieure, de préférence de manière étanche. Une pièce distincte 3 du corps mobile formant un fond ou couvercle est rapportée sur le corps mobile 11 pour fermer une ouverture destinée au montage du mécanisme de déclenchement à l'intérieur du corps mobile 11. De manière optionnelle et avantageuse, ce fond ferme le corps mobile de manière sensiblement étanche. De plus, selon un mode de réalisation avantageux, ce fond est amovible à l'intérieur de l'agrippe talon 10.The triggering threshold can be modified in known manner by modifying the degree of compression of the spring 15 by a set screw 19 positioned at the rear end of the movable body 11 and able to move the stopper 16 internally along the movable body 11. The movable body 11 thus has the particularity of being closed in its lower part, preferably in a sealed manner. A separate part 3 of the movable body forming a bottom or cover is attached to the movable body 11 to close an opening for mounting the trigger mechanism inside the movable body 11. Optionally and advantageously, this bottom closes the body movably substantially sealed. In addition, according to an advantageous embodiment, this bottom is removable inside the heel gripper 10.

Dans ce mode de réalisation, la surface de déclenchement 18 est formée par une saillie 21 de l'axe d'articulation, particulièrement visible sur les figures 3 et 4. Cette saillie se présente au moins au niveau de la partie centrale de l'axe d'articulation 14, est orientée vers l'arrière de la talonnière de sorte à coopérer avec le piston du mécanisme de déclenchement, globalement du côté opposé à l'agrippe talon 10 par rapport à l'axe d'articulation 14. Elle forme un volume en relief extérieur au cylindre dans lequel la partie de l'axe d'articulation disposée vers l'avant de la talonnière s'inscrit. La saillie 21 est donc disposée en relief par rapport au reste de l'axe d'articulation 14. Elle peut notamment s'étendre sur au moins une partie de la longueur de l'axe d'articulation 14 dans la direction transversale. Dans l'exemple représenté, sa section est constante le long de l'axe d'articulation 14. Elle remplit une fonction supplémentaire de renfort de l'axe d'articulation 14 à la manière d'une nervure de rigidification en plus de sa fonction principale de déclenchement. La rigidité ainsi apportée par la saillie 21 permet avantageusement de prévoir des dimensions relativement faibles de la section de l'axe d'articulation 14 en dehors de la zone de saillie. D'autre part, elle permet même d'envisager l'utilisation d'un matériau économique et léger, comme un simple plastique par exemple, éventuellement renforcé par des fibres de verre ou tout équivalent. Cette solution devient en outre moins coûteuse que les solutions de l'état de la technique qui nécessitent le recours à une pièce métallique.In this embodiment, the triggering surface 18 is formed by a projection 21 of the hinge axis, particularly visible on the Figures 3 and 4 . This projection is at least at the level of the part central of the hinge axis 14, is oriented towards the rear of the heel so as to cooperate with the piston of the trigger mechanism, generally on the opposite side to the gripping heel 10 relative to the axis of articulation 14. It forms a raised volume outside the cylinder in which the portion of the hinge pin disposed towards the front of the heel piece. The projection 21 is thus arranged in relief relative to the rest of the hinge axis 14. It may in particular extend over at least a portion of the length of the hinge axis 14 in the transverse direction. In the example shown, its section is constant along the hinge axis 14. It performs an additional function of reinforcing the hinge pin 14 in the manner of a stiffening rib in addition to its function main trigger. The rigidity provided by the projection 21 advantageously allows to provide relatively small dimensions of the section of the hinge axis 14 outside the projection area. On the other hand, it even allows to consider the use of a lightweight and economical material, such as a simple plastic for example, possibly reinforced with glass fibers or any equivalent. This solution also becomes less expensive than the solutions of the state of the art which require the use of a metal part.

Dans un mode de réalisation avantageux en termes de poids et de simplicité, et comme l'illustre la figure 5 par exemple, l'axe d'articulation 14 peut adopter une forme globalement tubulaire, i.e. délimitant intérieurement un alésage lui permettant de recevoir un insert de renfort 25, plein ou creux, disposé à l'intérieur de l'axe 14, de manière à renforcer la talonnière.In an advantageous embodiment in terms of weight and simplicity, and as illustrated by figure 5 for example, the hinge pin 14 may adopt a generally tubular shape, ie internally defining a bore allowing it to receive a reinforcing insert 25, solid or hollow, disposed inside the axis 14, so as to strengthen the heel.

Les bras latéraux 20 délimitent un espace entre les extrémités transversales de la saillie 21 et eux-mêmes de sorte à pouvoir recevoir le corps mobile 11. Le corps mobile 11 est équipé dans sa partie antérieure d'un carter globalement fermé à l'exception de deux ouvertures 26 ménagées transversalement dans des flancs latéraux de ce carter afin de laisser l'axe 14 le traverser de part en part à travers ce carter. Chacun des espaces entre un bras 20 et une extrémité de saillie 21 est destinée à recevoir un flanc latéral du carter.The lateral arms 20 delimit a space between the transverse ends of the projection 21 and themselves so as to be able to receive the movable body 11. The movable body 11 is equipped in its anterior part of a generally closed casing except for two openings 26 formed transversely in lateral flanks of this casing in order to allow the shaft 14 to pass through it from one side to the other. Each of the spaces between an arm 20 and a projecting end 21 is intended to receive a lateral flank of the housing.

Le montage d'une telle talonnière comprend les étapes importantes suivantes : l'axe d'articulation 14 est d'abord inséré dans le corps mobile 11 par l'ouverture 26, puis le corps mobile après son assemblage finalisé est intégré par le haut en force entre les bras 20 qui sont légèrement écartés élastiquement pendant cette opération, puis l'ensemble obtenu reçoit l'insertion de deux rondelles 28 pour le blocage en rotation. Ces rondelles peuvent présenter une surface pleine, comme représenté par exemple sur la figure 1, ou en variante une surface partiellement creuse, comme représenté sur la figure 5. En remarque, l'axe d'articulation présente une longueur légèrement supérieure à l'écartement au repos des deux bras 20. De plus, les ouvertures 27 des bras latéraux 20 comprennent un format indépendant de celui de l'axe d'articulation 14 qui ne passe pas au travers lors du montage de la talonnière, et peuvent notamment présenter une section plus petite que celle de l'axe d'articulation au niveau de la saillie. Au contraire, l'ouverture 26 du corps mobile présente une forme non circulaire pour pouvoir recevoir l'axe et sa saillie. De plus, cette ouverture 26 est au moins partiellement recouverte par les bras latéraux 20 après le montage de la talonnière.The mounting of such a heel comprises the following important steps: the hinge pin 14 is first inserted into the movable body 11 through the opening 26, then the movable body after its final assembly is integrated from above into force between the arms 20 which are slightly apart elastically during this operation, then the assembly obtained receives the insertion of two washers 28 for locking in rotation. These washers may have a solid surface, as represented for example on the figure 1 , or alternatively a partially hollow surface, as shown in FIG. figure 5 . As a remark, the hinge axis has a length slightly greater than the spacing at rest of the two arms 20. In addition, the openings 27 of the lateral arms 20 comprise a format independent of that of the hinge pin 14 which does not pass through during assembly of the heel, and may in particular have a smaller section than that of the hinge pin at the projection. On the contrary, the opening 26 of the movable body has a non-circular shape to receive the axis and its projection. In addition, this opening 26 is at least partially covered by the side arms 20 after mounting the heel.

Dans cette solution, la languette 30 est obtenue par deux pièces distinctes 2, 22, dont une pièce 2 formant la couche supérieure de la languette 30 appartient à une pièce distincte 3 du reste de la talonnière, et notamment du corps 11 et de l'agrippe-talon 10. Cette pièce distincte 3 est ensuite assemblée avec les autres composants de la talonnière pour atteindre son positionnement final représenté sur les différentes figures.In this solution, the tongue 30 is obtained by two separate parts 2, 22, a part 2 forming the upper layer of the tongue 30 belongs to a separate part 3 of the rest of the heel, and in particular the body 11 and the Heel grip 10. This separate part 3 is then assembled with the other components of the heel piece to reach its final position shown in the various figures.

Comme illustré par les figures 1 à 6, la couche supérieure 2 de la languette 30 appartient à une pièce distincte 3 du corps mobile 11 et de l'agrippe-talon 10, qui forme le fond de l'agrippe-talon 10. Cette pièce distincte 3 comprend la couche supérieure 2 de la languette, qui s'étend vers l'avant dans la direction de l'axe du corps 11, et une paroi 4 sensiblement perpendiculaire qui remonte jusqu'au niveau de la partie supérieure de l'agrippe-talon 10, et occupe une largeur sensiblement égale à celle de la languette 30, formant aussi une frontière entre le corps mobile et l'extérieur, en remplissant une fonction de fermeture et d'étanchéité de ce corps mobile. En variante, cette paroi 4 sensiblement perpendiculaire peut recouvrir une paroi pleine de l'agrippe-talon, et ne pas former un fond étanche. Cette pièce distincte 3 est fixée à l'agrippe-talon 10 par un clipsage à l'aide de plusieurs éléments de fixation 5 répartis sur son contour. Dans ce mode de réalisation, elle est fixée de manière amovible, et peut être retirée et changée, de manière conviviale et manuelle, comme cela est illustré par la figure 6.As illustrated by Figures 1 to 6 the upper layer 2 of the tongue 30 is part of a separate part 3 of the movable body 11 and the heel catch 10 which forms the bottom of the heel catch 10. This separate part 3 comprises the upper layer 2 of the tongue, which extends forward in the direction of the axis of the body 11, and a substantially perpendicular wall 4 which rises to the level of the upper part of the heel grip 10, and occupies a width substantially equal to that of the tongue 30, also forming a boundary between the movable body and the outside, by fulfilling a function of closing and sealing of the movable body. In a variant, this substantially perpendicular wall 4 may cover a solid wall of the heel grip, and not form a sealed bottom. This separate piece 3 is fixed to the heel grip 10 by clipping with the aid of several fastening elements 5 distributed over its contour. In this embodiment, it is removably attached, and can be removed and changed in a user-friendly and manual manner, as illustrated by the figure 6 .

La figure 7 illustre une variante de réalisation, dans laquelle la pièce distincte 3' assemblée à l'extrémité avant de l'agrippe talon 10 de la talonnière se réduit à sensiblement la couche supérieure 2' de la languette 30.The figure 7 illustrates an alternative embodiment, wherein the separate piece 3 'assembled at the front end of the heel grip 10 of the heel is reduced to substantially the upper layer 2' of the tongue 30.

Les figures 8 et 9 illustrent une autre variante de réalisation, dans laquelle la pièce distincte 3" comprend la couche supérieure 2" de la languette et une paroi 4" sensiblement perpendiculaire qui remonte jusqu'au niveau de la partie supérieure de l'agrippe-talon 10 et occupe une largeur maximale Imax dans sa partie haute plus large que la largeur Llan de la languette. D'autre part, comme cela est plus particulièrement visible sur la coupe de la figure 9, la surface frontale de la paroi 4" perpendiculaire de la pièce distincte 3" vient dans le prolongement de la surface frontale de l'agrippe-talon 10, notamment au niveau des ailettes 13 de l'agrippe-talon, dans la zone où la paroi 4" occupe sa largeur maximale. Cette continuité des surfaces, au niveau de leur ligne de liaison, est de préférence agencée sur toute la surface de la pièce distincte 3", et avantageusement au moins sur toute sa surface de sa paroi 4" sensiblement perpendiculaire. Cette configuration, qui forme une surface frontale continue de la talonnière, présente l'avantage de faciliter le chaussage et de ne pas gêner les déclenchements de la talonnière.The Figures 8 and 9 illustrate another alternative embodiment, wherein the separate part 3 "comprises the upper layer 2" of the tongue and a substantially perpendicular wall 4 "which goes up to the level of the upper part of the heel grip 10 and occupies a maximum width I max in its upper part wider than the width L lan of the tongue On the other hand, as is more particularly visible on the section of the figure 9 , the front surface of the wall 4 "perpendicular to the separate piece 3" comes in the extension of the front surface of the heel catch 10, in particular at the level of the fins 13 of the heel catch, in the zone where the wall 4 "occupies its maximum width.This continuity of the surfaces, at their connecting line, is preferably arranged over the entire surface of the separate part 3 ", and advantageously at least over its entire surface of its wall 4" substantially perpendicular.This configuration, which forms a continuous frontal surface of the heel, has the advantage of facilitating the footwear and not to interfere with the triggers of the heel.

Dans les exemples illustrés, la pièce distincte 3, 3', 3" vient se fixer sur l'agrippe-talon, dans la partie avant du corps mobile. Dans ces exemples, cette pièce distincte se fixe sur un ensemble monolithique qui s'étend de l'arrière de la talonnière jusqu'à l'agrippe-talon. De plus, la languette est finalement formée par la réunion de la couche supérieure 2, 2', 2" qui appartient à la pièce distincte 3, 3', 3", sur laquelle vient reposer la chaussure de ski au moins pendant le chaussage, et d'une partie plane formant une base 22 qui s'étend vers l'avant et qui appartient à l'ensemble monolithique de la talonnière mentionné ci-dessus.In the illustrated examples, the separate part 3, 3 ', 3 "is fixed on the bead clip, in the front part of the moving body.In these examples, this separate part is fixed on a monolithic assembly which extends from the back of the heel to the heel catch, and the tongue is finally formed by the joining of the upper layer 2, 2 ', 2 "which belongs to the separate piece 3, 3', 3 ", on which comes to rest the ski boot at least during donnage, and a flat portion forming a base 22 which extends forward and which belongs to the monolithic assembly of the heel piece mentioned above.

Dans tous les cas, cette solution présente par exemple l'avantage de pouvoir choisir un matériau optimal pour la couche supérieure 2, 2', 2" de la languette, différent des matériaux utilisés pour le reste de la talonnière et notamment le corps 11 et/ou l'agrippe-talon 10. Dans le mode de réalisation, ce matériau est un matériau qui présente une bonne rigidité et résistance, pour résister aux efforts importants subis par la languette, notamment par la pression vers le bas d'une chaussure lors d'une phase de chaussage, et qui présente un faible coefficient de frottement pour faciliter la libération d'une chaussure, en garantissant sa non adhésion sur la couche supérieure 2, 2' de la languette et également sur la partie verticale 4 dans la première variante de réalisation dans une phase de déclenchement de la fixation. A titre d'exemple, la couche supérieure de la languette peut être en polyoxyméthylène (POM) ou en polyamide, et/ou éventuellement dans un matériau chargé en téflon.In all cases, this solution has for example the advantage of being able to choose an optimal material for the upper layer 2, 2 ', 2 "of the tongue, different from the materials used for the rest of the heel and in particular the body 11 and In the embodiment, this material is a material that has a good rigidity and resistance, to withstand the significant forces experienced by the tongue, in particular by the downward pressure of a shoe when a boot phase, and which has a low coefficient of friction to facilitate the release of a shoe, ensuring its non-adhesion on the upper layer 2, 2 'of the tongue and also on the vertical portion 4 in the first variant embodiment in a phase of triggering the attachment, for example the upper layer of the tongue may be polyoxymethylene (POM) or polyamide, and / or optionally in a teflon-loaded material.

D'autre part, la forme de la languette peut aussi être optimisée, en augmentant son épaisseur et/ou sa longueur par rapport aux solutions existantes, pour notamment faciliter le chaussage. Ainsi, l'épaisseur e de la languette peut être supérieure ou égale à 5 mm, voire 7 mm. A titre d'exemple, l'épaisseur de la couche supérieure 2, 2' de la languette peut être comprise entre 2 et 6 mm. De plus, il est envisageable d'augmenter sa longueur par rapport aux solutions existantes.On the other hand, the shape of the tongue can also be optimized, increasing its thickness and / or its length compared to existing solutions, in particular to facilitate the boot. Thus, the thickness e of the tongue may be greater than or equal to 5 mm, or even 7 mm. For example, the thickness of the upper layer 2, 2 'of the tongue may be between 2 and 6 mm. In addition, it is possible to increase its length compared to existing solutions.

De plus, dans le mode de réalisation où la languette est amovible, un utilisateur peut disposer de plusieurs languettes différentes, destinées à une même talonnière, ce qui lui permet de modifier sa talonnière selon son souhait, selon son utilisation, etc. Par exemple, il peut ainsi adapter sa talonnière à différentes chaussures légèrement différentes, uniquement par l'intermédiaire de languettes de formes différentes, sans modifier le réglage de la talonnière sur son ski. A titre d'exemple, il peut disposer de deux languettes respectivement dédiées à ses chaussures de ski alpin et de ski de randonnée, et/ou dédiées à deux chaussures de ski alpin de même pointure respectivement adulte et junior. Selon un autre exemple, les différentes languettes peuvent simplement permettre de modifier l'aspect esthétique de la talonnière, en présentant des formes et/ou couleurs différentes par exemple, ce qui permet à un utilisateur de personnaliser sa talonnière et de faire évoluer à sa guise son aspect esthétique.In addition, in the embodiment where the tongue is removable, a user can have several different tongues, for the same heel, which allows him to modify his heel according to his wishes, according to its use, etc. For example, he can adapt his heel to different shoes slightly different, only through tabs of different shapes, without changing the heel setting on his ski. For example, it may have two tabs respectively dedicated to its alpine ski boots and ski touring, and / or dedicated to two alpine ski boots of the same size respectively adult and junior. In another example, the different tabs may simply allow to modify the aesthetic appearance of the heel, by presenting different shapes and / or colors, for example, which allows a user to customize his heel and to change as he wishes its aesthetic appearance.

La solution ainsi retenue et décrite ci-dessus est finalement adaptée pour toute talonnière de dispositif de fixation de chaussure. Elle peut notamment être aussi implémentée sur une talonnière à corps fixe qui intègre un ressort de déclenchement, en particulier comprenant un agrippe-talon articulé sur ce corps fixe. Elle est aussi adaptable à toute chaussure de sport qui doit être fixée sur une planche de glisse. Elle ne se limite naturellement pas aux exemples décrits et peut être mise en oeuvre par l'intermédiaire d'une pièce distincte du reste de la talonnière, qui forme tout ou partie de la languette de la talonnière, plus exactement tout ou partie de sa surface supérieure et/ou de son épaisseur e sur laquelle la chaussure vient en appui. Cette pièce distincte peut ainsi prendre une forme de plus petite ou de plus grande surface que les exemples représentés. Par exemple, la pièce distincte 3, 3' peut occuper une surface qui recouvre toute la partie antérieure de l'agrippe-talon, s'étendant d'une extrémité latérale à une autre et jusqu'aux ailettes 13 de l'agrippe-talon 10 en hauteur. En variante, elle peut se limiter à une petite surface de la languette. De plus, la pièce distincte a été présentée comme pouvant être amovible. En variante, elle pourrait naturellement être non amovible, fixée sur la talonnière par des dispositifs de fixation définitifs, comme un collage ou une soudure, ou par des dispositifs non adaptés pour le retrait et l'échange de la pièce, comme avec des vis par exemple. Enfin, la pièce distincte peut se présenter en plusieurs parties indépendantes, et/ou en plusieurs parties dans des matériaux différents, obtenus par exemple par plusieurs étapes d'injection.The solution thus retained and described above is finally suitable for any shoe binding device heel. It may in particular also be implemented on a fixed-body heel which incorporates a trigger spring, in particular comprising a articulated heel grip on this fixed body. It is also adaptable to any sports shoe that must be fixed on a gliding board. It is naturally not limited to the examples described and can be implemented through a separate part of the rest of the heel, which forms all or part of the tongue of the heel, more exactly all or part of its surface upper and / or its thickness on which the shoe bears. This distinct piece can thus take a shape of smaller or larger surface than the examples shown. For example, the separate part 3, 3 'can occupy a surface which covers the entire anterior part of the heel catch, extending from one lateral end to another and to the fins 13 of the heel gripper. 10 in height. Alternatively, it can be limited to a small surface of the tongue. In addition, the separate piece has been shown as removable. Alternatively, it could of course be non-removable, fixed on the heel by final fasteners, such as gluing or welding, or by devices not suitable for the removal and exchange of the part, as with screws by example. Finally, the separate part may be in several independent parts, and / or in several parts in different materials, obtained for example by several injection steps.

La solution atteint bien les buts recherchés et présente les avantages d'être économique, esthétique, et conviviale.The solution achieves the desired goals and has the advantages of being economical, aesthetic, and user-friendly.
