The buffer has a support surface (18a) that abuts against the bottom of a sole (11) of the ski boot. The support surface forms an angle with respect to a plane parallel to the upper surface of the ski, where the angle ranges between 0 and 80 degrees. A retaining device (5) includes a fixed jaw (7) and a movable jaw (8) that is movable between a spaced position and a close position. The buffer is made of thermoplastic material.

Description

L'invention est relative à une fixation de ski pour la pratique du ski nordique dans laquelle le skieur soulève alternativement le talon, telle que la pratique du télémark, de la randonnée à ski, du ski-roues ou du ski de fond. L'invention est également relative à un ski comprenant une telle fixation.The invention relates to a ski binding for the practice of Nordic skiing in which the skier raises the heel alternately, such as telemark, ski touring, ski-wheels or cross-country skiing. The invention also relates to a ski comprising such a binding.

Les fixations de ski pour la pratique du ski nordique comportent généralement une platine pourvue d'un dispositif de retenue permettant de fixer de manière amovible la chaussure de ski d'un utilisateur.Ski bindings for Nordic skiing generally comprise a plate provided with a retaining device for removably fixing the ski boot of a user.

Dans une telle fixation, la chaussure s'assemble au ski à son extrémité avant avec possibilité de rotation autour d'une barre transversale, généralement un pivot, solidaire de la chaussure. De façon connue, le pivot transversal de la chaussure est maintenu entre une mâchoire fixe et une mâchoire mobile du dispositif de retenue. La mâchoire mobile est montée sur un chariot monté déplaçable longitudinalement selon l'axe du ski, et peut être manoeuvré à l'aide d'un levier.In such a binding, the shoe assembles with the ski at its front end with the possibility of rotation around a crossbar, generally a pivot, integral with the shoe. In known manner, the transverse pivot of the shoe is held between a fixed jaw and a movable jaw of the retainer. The movable jaw is mounted on a carriage mounted longitudinally movable along the axis of the ski, and can be manipulated using a lever.

Le dispositif de retenue délimite par ailleurs un logement pour un tampon élastique présentant une surface d'appui coopérant avec une face verticale du bout de la chaussure de ski. Le tampon élastique est destiné à exercer un effort de rappel sur la chaussure lorsque le talon de celle-ci est soulevé de la surface supérieure du ski.The retainer further defines a housing for an elastic buffer having a bearing surface cooperating with a vertical face of the end of the ski boot. The elastic pad is intended to exert a return force on the shoe when the heel of the latter is raised from the upper surface of the ski.

Pour coopérer avec le tampon élastique, les chaussures de ski présentent des renforts à leurs extrémités avant, ceux-ci permettant d'éviter une déformation trop importante de la pointe de la chaussure de ski.To cooperate with the elastic pad, the ski boots have reinforcements at their front ends, these to prevent excessive deformation of the tip of the ski boot.

La tige est alors moins souple en bout de pied qu'à d'autres niveaux, ce qui peut occasionner une gêne à l'utilisateur après une utilisation prolongée.The rod is then less flexible at the foot of other levels, which can cause discomfort to the user after prolonged use.

En outre, le bout du pied de l'utilisateur ne permet pas toujours à l'utilisateur de disposer d'un appui stable permettant d'obtenir un contrôle satisfaisant du guidage du ski et une transmission appropriée des sensations sensorielles au niveau du pied de l'utilisateur.In addition, the tip of the user's foot does not always allow the user to have a stable support to obtain a satisfactory control of the ski guide and an appropriate transmission of sensory sensations at the foot of the foot. 'user.

La présente invention vise donc à proposer une fixation améliorée, permettant notamment un meilleur guidage du ski en optimisant les transmissions d'impulsions de conduite ou d'informations sensorielles entre le skieur et le ski.The present invention therefore aims to provide an improved attachment, including a better guide of the ski by optimizing the transmission of driving impulses or sensory information between the skier and the ski.

A cet effet, l'invention a pour objet une fixation de ski comportant un tampon élastique destiné à exercer un effort de rappel sur une chaussure lorsque le talon de celle-ci est soulevé de la surface supérieure du ski, caractérisée en ce que ledit tampon élastique présente une surface d'appui destinée à venir en butée avec le dessous de la semelle de la chaussure de ski et dont l'angle entre ladite surface d'appui et un plan sensiblement parallèle à la surface supérieure du ski, est compris entre 0 et 80°.For this purpose, the subject of the invention is a ski binding comprising an elastic buffer intended to exert a return force on a boot when the heel of the latter is raised from the upper surface of the ski, characterized in that said pad spring has a bearing surface intended to abut with the underside of the sole of the ski boot and whose angle between said bearing surface and a plane substantially parallel to the upper surface of the ski, is between 0 and 80 °.

L'angle est mesuré alors que le tampon élastique n'est pas soumis à une déformation en compression sur sa surface d'appui. Par exemple, l'angle entre ladite surface d'appui et un plan sensiblement parallèle à la surface supérieure du ski est compris entre 0 et 40°.The angle is measured while the elastic pad is not subjected to deformation in compression on its bearing surface. For example, the angle between said bearing surface and a plane substantially parallel to the upper surface of the ski is between 0 and 40 °.

Ainsi, au cours de la compression du tampon élastique, la surface d'appui ne vient plus en butée face au pied de l'utilisateur mais est décalée sous son pied, ce qui permet d'accroître la force disponible par l'utilisateur puisque celui-ci exerce un effort essentiellement vertical, lui procurant également une meilleure stabilité des appuis et une plus grande précision de mouvement.Thus, during the compression of the elastic pad, the bearing surface no longer abuts the user's foot but is shifted under its foot, which increases the force available to the user since that it exerts an essentially vertical force, also giving it a better stability of the supports and a greater precision of movement.

L'effet de levier autour du pivot transversal de la chaussure est accentué de sorte que l'on réduit la torsion de la chaussure au niveau de la tige et de la semelle, ce qui permet un meilleur contrôle du guidage du ski.The leverage around the transverse pivot of the shoe is accentuated so that the torsion of the shoe is reduced at the level of the upper and the sole, which allows a better control of the ski guidance.

En outre, la sensation de confort est progressive dans toute la chaussure, l'utilisateur n'observe plus de rupture dans la souplesse de la semelle de la chaussure. Il dispose alors d'une meilleure transmission sensorielle entre son pied et le ski.In addition, the feeling of comfort is progressive throughout the shoe, the user no longer observes a break in the flexibility of the sole of the shoe. He then has a better sensory transmission between his foot and the ski.

Selon une forme de réalisation, la fixation comporte un dispositif de retenue comprenant une mâchoire fixe et une mâchoire mobile entre une position écartée et une position rapprochée de ladite mâchoire fixe, la distance entre la mâchoire fixe et une arête arrière de la surface d'appui du tampon élastique étant inférieure à 10 millimètres dans la position rapprochée. En fait selon cette forme de réalisation le tampon élastique est solidaire de la mâchoire mobile. Ainsi le tampon se rapproche ou s'éloigne de la mâchoire fixe en même temps que la mâchoire mobile.According to one embodiment, the attachment comprises a retaining device comprising a fixed jaw and a movable jaw between a spaced apart position and a close position of said fixed jaw, the distance between the fixed jaw and a rear edge of the bearing surface. elastic buffer being less than 10 millimeters in the close position. In fact according to this embodiment the elastic buffer is integral with the movable jaw. Thus, the pad moves toward or away from the fixed jaw at the same time as the movable jaw.

On dispose alors d'un espace suffisant entre la mâchoire fixe et l'arête arrière de la surface d'appui pour permettre le basculement de la chaussure de ski sur la fixation sans pour autant nécessiter de cale de rehaussage ou de cavité particulière ménagée dans la fixation.There is then sufficient space between the fixed jaw and the rear edge of the bearing surface to allow the tying of the ski boot on the binding without requiring a special wedge or cavity made in the fixation.

De plus, une même fixation convient alors pour différents types de semelles de chaussure présentant un pivot transversal et ce, quelle que soit la forme de ladite semelle ou la position de la barre transversale sous ladite semelle.In addition, the same attachment is then suitable for different types of shoe soles having a transverse pivot and this, whatever the shape of said sole or the position of the crossbar under said sole.

  • ledit tampon élastique comporte un matériau thermoplastique présentant une dureté comprise entre 35 et 95 Shore A,
  • ledit tampon élastique présente une forme en accordéon,

  • ladite arête de guidage est segmentée par au moins une fente transversale,
  • ladite arête de guidage se prolonge à l'avant par ladite mâchoire fixe.

The carriage 9 can be operated manually with the aid of FIG. a lever 10 of the retainer 5. It can also be provided that the carriage can be moved automatically (not shown). The carriage 9 is provided at the front of the attachment 3 on the gliding board 2. Note that the movable jaw is located more towards the front of the attachment 3 than is the fixed jaw. However the opposite is possible.

La chaussure 6 comporte une semelle 11 sur laquelle est solidarisée une tige 12 présentant une ouverture 13 pour l'introduction d'un pied d'un utilisateur.The shoe 6 has a sole 11 on which is secured a rod 12 having an opening 13 for the introduction of a foot of a user.

La semelle 11 et la tige 12 s'étendent longitudinalement selon l'axe longitudinal L' depuis le talon 14 à une extrémité arrière jusqu'à la pointe 15 à une extrémité avant, l'axe longitudinal L' de la semelle 11 et l'axe longitudinal L du ski 1 étant sensiblement parallèles.The sole 11 and the rod 12 extend longitudinally along the longitudinal axis L 'from the heel 14 at a rear end to the tip 15 at a front end, the longitudinal axis L' of the sole 11 and the longitudinal axis L of the ski 1 being substantially parallel.

La chaussure 6 présente en outre une première barre transversale ou premier pivot 16, sensiblement perpendiculaire à l'axe longitudinal L' de la chaussure 6 et solidaire de la semelle 11, disposé à l'avant de la semelle 11. Les extrémités du pivot transversal 16 sont noyées dans la semelle 11.The shoe 6 further has a first transverse bar or first pivot 16, substantially perpendicular to the longitudinal axis L 'of the shoe 6 and integral with the sole 11, disposed at the front of the sole 11. The ends of the transverse pivot 16 are embedded in the sole 11.

Le pivot transversal 16 de la chaussure 6 est configuré pour pouvoir s'insérer entre la mâchoire fixe 7 et la mâchoire mobile 8 de la fixation 3 en position écartée et être maintenu par elles en position rapprochée, interdisant ainsi au pivot transversal 16 de sortir de son logement, fixant alors l'avant de la chaussure 6 au ski 1. Le pivot ou barre 16 présente une section circulaire, mais d'autres formes de section pourraient convenir.The transverse pivot 16 of the shoe 6 is configured to fit between the fixed jaw 7 and the movable jaw 8 of the attachment 3 in the spaced apart position and be held by them in a close position, thus preventing the transverse pivot 16 from coming out of its housing, then fixing the front of the shoe 6 to the ski 1. The pivot or bar 16 has a circular section, but other sectional shapes may be suitable.

Le pivot transversal 16 est disposé sous la semelle 11 de la chaussure 1 par exemple à une distance d1 comprise entre 13 et 20 millimètres au droit de l'extrémité avant de la semelle 11 (figure 2). Plus précisément, la distance d1 est la distance entre l'axe du pivot transversal 16 et une projection imaginaire de l'extrémité avant de la semelle 11 dans un plan parallèle à la surface du ski contenant l'axe du pivot transversal 16.The transverse pivot 16 is placed under the sole 11 of the boot 1, for example at a distance d1 between 13 and 20 millimeters to the right of the front end of the sole 11 ( figure 2 ). More specifically, the distance d1 is the distance between the axis of the transverse pivot 16 and an imaginary projection of the front end of the sole 11 in a plane parallel to the surface of the ski containing the axis of the transverse pivot 16.

Le dispositif de retenue 5 de la fixation 3 délimite par ailleurs un logement (non visible) pour un tampon élastique 17. Le logement est par exemple ménagé dans le chariot 9, entre les bras du levier 10 de fixation 3.The retaining device 5 of the attachment 3 also delimits a housing (not visible) for an elastic buffer 17. The housing is for example arranged in the carriage 9, between the arms of the fixing lever 3.

Le tampon élastique 17 présente une surface d'appui 18a sur sa paroi supérieure, destinée à venir en butée avec une surface de butée 18b située dans un dégagement 25 en dessous de la semelle 11 de la chaussure de ski 6. Ainsi que le montrent les figures 1 à 4, la surface de butée 18b peut présenter une forme bombée légèrement convexe.The elastic pad 17 has a bearing surface 18a on its upper wall, intended to abut with an abutment surface 18b located in a clearance 25 below the sole 11 of the ski boot 6. As shown in FIGS. Figures 1 to 4 the abutment surface 18b may have a convexly convex shape.

Le tampon élastique 17 est destiné à exercer un effort de rappel sur la chaussure 6 lorsque le talon 14 de celle-ci est soulevé de la surface supérieure S du ski 1. Ainsi, une fois le ski et la chaussure assemblés, la chaussure 6 peut pivoter autour du pivot transversal 16 à l'encontre du tampon élastique 17.The elastic buffer 17 is intended to exert a return force on the shoe 6 when the heel 14 thereof is raised from the upper surface S of the ski 1. Thus, once the ski and the shoe assembled, the shoe 6 can pivot about the transverse pivot 16 against the elastic buffer 17.

Comme on peut le voir sur la figure 1, l'angle α entre la surface d'appui 18a et un plan sensiblement parallèle à la surface supérieure S du ski 1, est compris entre 0 et 80°. L'angle α est mesuré alors que le tampon élastique 17 n'est pas soumis à une déformation en compression sur sa surface d'appui 18a. Par exemple, l'angle α est compris entre 0 et 40°.As can be seen on the figure 1 the angle α between the bearing surface 18a and a plane substantially parallel to the upper surface S of the ski 1 is between 0 and 80 °. The angle α is measured while the elastic pad 17 is not subjected to compressive deformation on its bearing surface 18a. For example, the angle α is between 0 and 40 °.

Ainsi, au cours de la compression du tampon élastique 17 (figure 4), la surface d'appui 18a ne vient plus en butée face aux orteils du pied de l'utilisateur mais est décalée sous son pied, ce qui permet d'accroître la force disponible par l'utilisateur, lui procurant également une meilleure stabilité des appuis et une plus grande précision de mouvement.Thus, during the compression of the elastic buffer 17 ( figure 4 ), the bearing surface 18a no longer abuts against the toes of the user's foot but is shifted under his foot, which increases the force available to the user, also giving him a better stability of the supports and a greater precision of movement.

L'effet de levier autour du pivot transversal 16 de la chaussure 6 est accentué de sorte que l'on réduit la torsion de la chaussure au niveau de la tige 12 et de la semelle 11, ce qui permet un meilleur contrôle du guidage du ski 1.The leverage around the transverse pivot 16 of the shoe 6 is accentuated so that the torsion of the shoe is reduced at the level of the upper 12 and the sole 11, which allows better control of the ski guidance. 1.

En outre, la sensation de confort est progressive dans toute la chaussure, l'utilisateur n'observe plus de rupture dans la souplesse de la semelle 11 de la chaussure. Il dispose alors d'une meilleure transmission sensorielle entre son pied et le ski. Il n'a plus la sensation de butée de ses orteils contre le tampon, d'où un meilleur confort.In addition, the feeling of comfort is progressive throughout the shoe, the user no longer observes a break in the flexibility of the sole 11 of the shoe. He then has a better sensory transmission between his foot and the ski. He no longer has the feeling of stop of his toes against the pad, hence a better comfort.

Selon une réalisation, la distance d2 entre la mâchoire fixe 7 et l'arête arrière de la surface d'appui 18a est inférieure à 10 millimètres lorsque la mâchoire mobile 8 est dans la position rapprochée (figure 3), par exemple la distance d2 est de l'ordre de 5 millimètres.According to one embodiment, the distance d2 between the fixed jaw 7 and the rear edge of the bearing surface 18a is less than 10 millimeters when the movable jaw 8 is in the close position ( figure 3 ), for example the distance d2 is of the order of 5 millimeters.

On remarque que la surface d'appui 18a du tampon élastique 17 est plus éloignée de la platine 4 ou du ski 1 que ne l'est le pivot 16. Ainsi le basculement de la chaussure 6, lorsque le talon 14 se soulève en s'éloignant de la platine 4, provoque une compression verticale du tampon élastique 17 par la pointe 15. Plus précisément c'est la partie de la semelle 11 située au niveau de la pointe 15, en avant du pivot 16, qui comprime le tampon 17. Alors la surface d'appui 18a descend vers la platine 4. Il peut arriver qu'un basculement important de la chaussure provoque un abaissement de tout ou partie de la surface d'appui 18a en dessous du niveau du pivot 16.Note that the bearing surface 18a of the elastic pad 17 is further away from the plate 4 or the ski 1 than the pivot 16. Thus the tilting of the shoe 6, when the heel 14 is raised in s' away from the plate 4, causes a vertical compression of the elastic pad 17 by the tip 15. More precisely it is the part of the sole 11 located at the tip 15, in front of the pivot 16, which compresses the pad 17. Then the bearing surface 18a descends towards the plate 4. It may happen that a large tilting of the boot causes a lowering of all or part of the bearing surface 18a below the level of the pivot 16.

En outre, une même fixation 3 convient pour différents types de semelles de chaussure présentant une barre transversale 16 et ce, quelle que soit la forme de ladite semelle ou la position de la barre transversale 16 sous ladite semelle.In addition, the same attachment 3 is suitable for different types of shoe insoles having a crossbar 16 and regardless of the shape of said sole or the position of the crossbar 16 under said sole.

Selon une forme de réalisation, le tampon élastique 17 comporte deux parties, à savoir une partie d'encastrement (non visible) et une partie conçue plus spécifiquement pour la déformation. La partie d'encastrement du tampon s'encastre dans le logement prévu à cet effet dans le dispositif de retenue de la fixation 3, tandis que la partie de déformation de ce tampon 17 est destinée à coopérer plus particulièrement avec la chaussure 6 par la surface d'appui 18a associée lors de la rotation de la chaussure 6 par rapport au ski 1.According to one embodiment, the elastic pad 17 comprises two parts, namely a recess portion (not visible) and a part designed more specifically for the deformation. The embedding portion of the buffer is embedded in the housing provided for this purpose in the fastener retaining device 3, while the deformation portion of the pad 17 is intended to cooperate more particularly with the shoe 6 by the surface associated support 18a during the rotation of the boot 6 relative to the ski 1.

Le logement ménagé dans le dispositif de retenue pour le tampon élastique 17 présente, en direction transversale, des dimensions supérieures à celles de ce tampon élastique 17 permettant une expansion en direction transversale du tampon 17 lors de sa compression par la chaussure 6, sans pour autant gêner sa pénétration à l'intérieur du logement.The housing formed in the retaining device for the elastic buffer 17 has, in transverse direction, dimensions greater than those of this elastic buffer 17 allowing expansion in the transverse direction of the buffer 17 during its compression by the boot 6, without however hinder its penetration inside the housing.

Dans sa partie de déformation, le tampon élastique 17 présente extérieurement une forme générale en accordéon, comprenant une série d'entailles 19 parallèles sur les parois latérales du tampon 17. Cette série d'entailles 19 délimite des couches dont la taille se réduit depuis la partie d'encastrement vers la surface d'appui 18a. En d'autres termes la partie de déformation présente une forme pyramidale, avec une base située à l'intersection des parties d'encastrement et de déformation. Le tampon élastique 17 présente également intérieurement une série de nervures (non visibles sur les figures) s'étendant parallèlement entre elles. Chaque nervure intérieure s'étend dans le prolongement d'une entaille 19. Les nervures intérieures sont destinées à exercer un certain effort de retenue des parois latérales du tampon élastique 17. Par contre, les entailles extérieures 19 sont destinées à permettre une meilleure compression du tampon élastique 17 par empilage des différentes couches successives déterminées entre chacune de ces entailles 19 (voir plus particulièrement la figure 4).In its deformation portion, the elastic pad 17 has a generally accordion-like shape, comprising a series of parallel notches 19 on the side walls of the pad 17. This series of notches 19 delimits layers whose size has been reduced since embedding portion to the bearing surface 18a. In other words the deformation portion has a pyramidal shape, with a base located at the intersection of the embedding and deformation parts. The elastic pad 17 also has internally a series of ribs (not visible in the figures) extending parallel to each other. Each inner rib extends in the extension of a notch 19. The inner ribs are intended to exert a certain retaining force of the side walls of the elastic pad 17. On the other hand, the outer cuts 19 are intended to allow a better compression of the elastic buffer 17 by stacking the different successive layers determined between each of these cuts 19 (see more particularly the figure 4 ).

Au final le tampon élastique 17 présente, dans sa partie de déformation, une forme sensiblement pyramidale allant en s'amincissant en direction de la surface d'appui 18a, ce qui permet un empilement des couches.Finally, the elastic pad 17 has, in its deformation portion, a substantially pyramidal shape tapering towards the bearing surface 18a, which allows a stack of layers.

En outre, le tampon élastique 17 présente dans le prolongement de sa surface d'appui 18a, à l'arête arrière, une languette d'accrochage 26 s'étendant vers le bas et destinée à s'ancrer dans une partie associée de la fixation 3. Cette languette d'accrochage est destinée à être fixée dans le logement au moyen d'une goupille 20 représentée sur la figure 3. La languette empêche, par son ancrage dans la fixation 3, tout décollement vers le haut du tampon élastique 17 lors du soulèvement de la chaussure 6, et donc lors de la compression de ce tampon élastique 17. Bien entendu, il peut être prévu d'autres moyens de solidarisation du tampon, comme par exemple un encastrement, un collage, ou autre.In addition, the elastic pad 17 has, in the extension of its bearing surface 18a, at the rear edge, a catch tab 26 extending downwards and intended to anchor in an associated part of the attachment. 3. This attachment tongue is intended to be fixed in the housing by means of a pin 20 shown on the figure 3 . The tongue prevents, by its anchoring in the binding 3, any upward detachment of the elastic pad 17 during the lifting of the shoe 6, and therefore during the compression of this elastic pad 17. Of course, it can be provided by other means of securing the buffer, such as embedding, gluing, or other.

On prévoit par exemple un tampon élastique 17 en élastomère, tel qu'en matériau thermoplastique. On prévoit par exemple un matériau SEBS (Styrène-Ethylène-Butadiène-Styrène), présentant une dureté comprise entre 35 et 95 Shore A.For example, an elastic buffer 17 made of elastomer, such as a thermoplastic material, is provided. For example, a material SEBS (Styrene-Ethylene-Butadiene-Styrene) having a hardness between 35 and 95 Shore A is provided.

La platine 4 peut également présenter une arête de guidage 21 longitudinale à l'axe longitudinal L du ski. L'arête de guidage 21 est destinée à coopérer avec une rainure 22 de forme complémentaire prévue sous la semelle 11 de la chaussure 6 pour le maintien latéral de la chaussure assemblée à la fixation 3 dans une première position dans laquelle le talon 14 de la chaussure est en appui sur le ski.The plate 4 may also have a longitudinal guide edge 21 to the longitudinal axis L of the ski. The guide edge 21 is intended to cooperate with a groove 22 of complementary shape provided under the sole 11 of the shoe 6 for lateral support of the shoe assembled to the binding 3 in a first position in which the heel 14 of the shoe is in support on the ski.

L'arête de guidage 21 présente par exemple une forme générale parallélépipédique ayant une longueur comprise entre 28 et 35 cm et une largeur de l'ordre de 2 cm. Elle peut se prolonger à l'avant par la mâchoire fixe 7.The guide edge 21 has for example a parallelepipedal overall shape having a length of between 28 and 35 cm and a width of about 2 cm. It can be extended at the front by the fixed jaw 7.

L'arête de guidage 21 peut être continue ou segmentée par au moins une fente transversale 23a, 23b. On prévoit par exemple que l'arête de guidage 21 est segmentée pour permettre au ski 1 de conserver une bonne flexibilité.The guide edge 21 may be continuous or segmented by at least one transverse slot 23a, 23b. For example, it is provided that the guide edge 21 is segmented to allow the ski 1 to maintain good flexibility.

De manière non limitative, l'arête de guidage 21 s'étend selon toute la longueur de la semelle de la chaussure.Without limitation, the guide edge 21 extends along the entire length of the sole of the shoe.

La semelle 11 de la chaussure présente par exemple une rainure de guidage longitudinale 22 de forme complémentaire s'étendant depuis la pointe 15 de la chaussure jusqu'au talon 14. La surface de butée 18b peut être disposée dans le prolongement à l'avant de la rainure de guidage 22. Il peut être prévu que le rebord supérieur de l'arête 21 contacte le fond de la rainure.The sole 11 of the shoe has for example a longitudinal guide groove 22 of complementary shape extending from the tip 15 of the shoe to the heel 14. The abutment surface 18b can be arranged in the extension to the front of the shoe. the guide groove 22. It may be provided that the upper edge of the edge 21 contacts the bottom of the groove.

La rainure de guidage 22 présente alors une forme générale parallélépipédique complémentaire avec par exemple une largeur de 3 cm. On peut bien sûr envisager d'autres formes de réalisation pour la rainure et l'arête de guidage, telles que des formes profilées trapézoïdales ou amincies vers l'extrémité arrière. On peut encore prévoir plusieurs arêtes de guidage.The guide groove 22 then has a complementary parallelepipedal general shape with for example a width of 3 cm. Of course, other embodiments can be envisaged for the groove and the guide edge, such as trapezoidal profiled shapes or thinned towards the rear end. It is also possible to provide several guide edges.

Selon une deuxième forme de réalisation, la semelle 11 de la chaussure de ski 6 présente une barre transversale ou pivot supplémentaire.According to a second embodiment, the sole 11 of the ski boot 6 has an additional transverse bar or pivot.

Dans une première variante de la deuxième forme de réalisation, non représentée, la platine de fixation comporte un crochet fixé à la platine par un moyen de rappel élastique permettant d'aider le skieur à rapprocher le talon vers le ski, lorsque le talon a été soulevé par rapport au ski. Par corollaire le ski reprend plus facilement une position parallèle à la semelle de la chaussure.In a first variant of the second embodiment, not shown, the fixing plate comprises a hook fixed to the plate by an elastic return means to help the skier to bring the heel towards the ski, when the heel has been raised with respect to the ski. As a corollary the ski takes over more easily a position parallel to the sole of the shoe.

Les figures 5 et 6 illustrent une deuxième variante de la deuxième forme de réalisation de la fixation. La chaussure et le ski présentent les mêmes éléments portant les mêmes références que dans la première forme de réalisation. La différence réside dans le fait que la semelle 11 de la chaussure de ski 6 est munie de la barre transversale ou du pivot supplémentaire 24. Le pivot transversal supplémentaire 24 est disposé en retrait du pivot transversal 16, il est par exemple espacé de 5 cm avec le pivot transversal 16. En d'autres termes le pivot supplémentaire 24 est situé plus en arrière que le premier pivot 16.The figures 5 and 6 illustrate a second variant of the second embodiment of the attachment. The shoe and the ski have the same elements bearing the same references as in the first embodiment. The difference lies in the fact that the sole 11 of the ski boot 6 is provided with the transverse bar or the additional pivot 24. The additional transverse pivot 24 is set back from the transverse pivot 16, it is for example spaced 5 cm with the transverse pivot 16. In other words the additional pivot 24 is located further back than the first pivot 16.

L'arête de guidage 21 est alors segmentée par une fente transversale 23b configurée pour le passage du pivot supplémentaire 24. La fente transversale 23 traverse donc l'arête de guidage 21 de part en part. Elle peut être droite (non représentée) ou présenter une forme arrondie suffisamment large pour le passage de la barre droite transversale supplémentaire 24.The guide edge 21 is then segmented by a transverse slot 23b configured for the passage of the additional pivot 24. The transverse slot 23 thus crosses the guide edge 21 from one side. It may be straight (not shown) or have a rounded shape large enough for the passage of the additional transverse straight bar 24.

Dans cette deuxième variante, la fonction de rappel de la barre transversale supplémentaire 24 est inactivée de sorte que l'utilisateur peut continuer à utiliser des chaussures qui en comportent. L'utilisateur peut alors être équipé de deux paires de ski et une seule paire de chaussures correspondante, une première paire de ski selon la première forme de réalisation et une deuxième paire de ski selon la deuxième forme de réalisation, la paire de chaussures pouvant être fixée indifféremment sur l'une ou l'autre des deux paires de ski. De même, l'utilisateur peut décider de conserver ses chaussures de ski déjà pourvues d'une barre transversale supplémentaire pour des skis ne présentant pas l'option du moyen de rappel.In this second variant, the return function of the additional crossbar 24 is inactivated so that the user can continue to use shoes that have them. The user can then be equipped with two pairs of skis and a single pair of corresponding shoes, a first pair of skis according to the first embodiment and a second pair of skis according to the second embodiment, the pair of shoes being able to be fixed indifferently on one or the other of the two pairs of ski. Similarly, the user may decide to keep his ski boots already provided with an additional crossbar for skis not having the option of the return means.

La fixation permet donc un meilleur guidage du ski en optimisant les transmissions d'impulsions de conduite ou d'informations sensorielles entre le skieur et le ski.The binding therefore allows better guidance of the ski by optimizing the transmission of driving impulses or sensory information between the skier and the ski.
