Description

L'invention a pour objet une chaussure pour la pratique du ski, notamment pour la pratique du ski alpin. Plus précisément, l'invention concerne les chaussures de ski qui comprennent une coque rigide réalisée en matière plastique à l'intérieur de laquelle est inséré un chausson interne réalisé en matériau souple.The invention relates to a shoe for skiing, especially for skiing downhill. More specifically, the invention relates to ski boots which comprise a rigid shell made of plastic material inside which is inserted an inner liner made of flexible material.

Depuis que ce type de chaussures de ski existe, différentes constructions ont été proposées par les fabricants. Il y eu notamment les chaussures dites à entrée arrière qui comportaient un spoiler arrière articulé dont le basculement vers l'arrière permettait l'introduction du pied. Dans une chaussure de ski à entrée arrière, la partie antérieure depuis l'avant du pied jusqu'au sommet de la chaussure, forme un bloc dont le volume extérieur n'est généralement pas réglable. L'adaptation de la chaussure au pied au pied du skieur doit alors se faire par un dispositif de serrage interne qui agit sur le chausson intérieur. Ce type de construction a depuis été abandonné par les fabricants, sauf pour les chaussures enfant, car outre le fait que les chaussures ainsi construites se révèlent peu performantes, elles sont volumineuses.Since this type of ski boots exists, different constructions have been proposed by the manufacturers. In particular, there were the so-called rear entry shoes, which included an articulated rear spoiler whose tilting backwards allowed the introduction of the foot. In a ski boot rear entry, the front from the front of the foot to the top of the shoe, form a block whose outer volume is generally not adjustable. The adaptation of the shoe to the foot at the foot of the skier must then be done by an internal clamping device that acts on the inner boot. This type of construction has since been abandoned by manufacturers, except for children's shoes, because besides the fact that the shoes thus built prove to be inefficient, they are bulky.

Une autre construction de coque de chaussure de ski est appelée « chaussure alpine à capot ». Dans ce type de chaussure, la coque se compose d'un bas de coque, d'un capot et d'un collier articulé. Le bas de coque comprend une large ouverture longitudinale qui s'étend depuis le haut de la chaussure jusqu'à l'avant du pied. Cette ouverture comprend deux bords latéraux qui ne se chevauchent pas. Le capot est articulé sur la coque au niveau de l'avant du pied et il est prévu pour recouvrir l'ouverture longitudinale de la coque Comme le capot est placé au-dessus de la coque, son basculement vers l'avant dégage complètement l'ouverture longitudinale. C'est dans cette position du capot que peut se faire très aisément le chaussage par le skieur. En effet, ce dernier peut facilement glisser son pied dans l'ouverture, laquelle se prolonge loin vers l'avant. Avec une telle chaussure, le skieur ne doit pas exercer un effort très important pour écarter les bords latéraux de l'ouverture. Cette construction est toujours utilisée, notamment pour les chaussures de ski de randonnée car elle offre une bonne facilité de chaussage et de desserrage. Cependant, il s'agit là encore d'une chaussure peu performante. D'autre part, le capot est une pièce volumineuse dont l'esthétique grossière ne satisfait plus les pratiquants.Another ski boot shell construction is called "Alpine Hooded Shoe". In this type of shoe, the shell consists of a shell bottom, a hood and an articulated collar. The lower shell has a large longitudinal opening that extends from the top of the shoe to the front of the foot. This opening has two side edges that do not overlap. The hood is hinged to the hull at the forefoot and is intended to cover the longitudinal opening of the hull As the hood is placed above the hull, its forward tilting completely releases the hull. longitudinal opening. It is in this position of the hood that can be done very easily the boot by the skier. Indeed, the latter can easily slide his foot into the opening, which extends far forward. With such a shoe, the skier must not exert a very important effort to spread the side edges of the opening. This construction is still used, especially for ski touring boots because it offers good ease of entry and loosening. However, this is still a poor performance shoe. On the other hand, the hood is a bulky piece whose rough aesthetics no longer satisfy the practitioners.

Enfin la construction la plus largement utilisée est celle appelée, chaussure alpine à overlap ou encore chaussure alpine à rabats se chevauchant. Dans cette construction, les bords latéraux de l'ouverture longitudinale se chevauchent. Ces chaussures sont particulièrement appréciées pour la compétition de ski et pour toute pratique performante du ski alpin. En effet, des frottements sont générés entre les deux rabats lorsqu'ils sont plaqués l'un contre l'autre. C'est grâce à ces frottements que ces chaussures offrent une bonne transmission des efforts, notamment lors de la flexion vers l'avant de la jambe du skieur. Cependant, le gros inconvénient de ces chaussures c'est la difficulté de chaussage et la difficulté de serrage. D'autre part, il est pratiquement nécessaire que le chausson intérieur placé dans une telle coque est équipé d'une plaque rigide de répartition des efforts générés par le serrage des boucles de serrage. En pratique, la plaque de répartition est constituée par une plaque faite en plastique moulé ou injecté qui est cousue sur la languette du chausson. Au final, ce ne sont pas moins de trois épaisseurs de plastique qui se superposent sur le cou-de-pied du skieur. Si bien que les chaussures à overlap sont plutôt lourdes, plutôt peu confortables et plutôt volumineuses.Finally, the most widely used construction is the so-called alpine shoe with overlap or alpine shoe with overlapping flaps. In this construction, the lateral edges of the longitudinal opening overlap. These shoes are particularly popular for ski racing and for all high-performance alpine skiing. Indeed, friction is generated between the two flaps when they are pressed against each other. It is thanks to these friction that these shoes offer a good transmission of efforts, especially during the forward bending of the skier's leg. However, the big disadvantage of these shoes is the difficulty of putting on and the difficulty of tightening. On the other hand, it is virtually necessary that the inner liner placed in such a shell is equipped with a rigid plate for distributing the forces generated by the tightening of the clamping loops. In practice, the distribution plate is constituted by a plate made of molded or injected plastic which is sewn on the tongue of the liner. In the end, no less than three layers of plastic overlap the skier's instep. So that shoes overlap are rather heavy, rather uncomfortable and rather bulky.

La présente invention vise à améliorer la construction des chaussures de ski alpin. Elle a pour objectif de fournir une chaussure de ski alpin qui ne présente pas les inconvénients des constructions de l'art antérieur. Il s'agit notamment de proposer une chaussure toute à la fois performante dans laquelle la transmission d'efforts depuis la jambe vers l'avant pied et le ski est efficace, confortable, légère, peu volumineuse, c'est-à-dire près du pied, et facile à enfiler.The present invention aims to improve the construction of alpine ski boots. Its purpose is to provide an alpine ski boot that does not have the disadvantages of prior art constructions. These include providing a shoe that is both powerful in which the transmission of effort from the leg to the forefoot and the ski is effective, comfortable, light, not bulky, that is to say close foot, and easy to put on.

Les différents objectifs sont atteints par la fourniture d'une chaussure de ski comportant une tige rigide constituée d'un bas de coque équipée d'une languette rigide et surmonté d'un collier articulé; dans laquelle le bas de coque comporte une large ouverture qui s'étend depuis le haut de la tige en direction de l'avant du pied, ladite ouverture séparant un bord latéral, d'un bord médial, lesquels s'étendent parallèlement l'un à l'autre sans se chevaucher ;et dans laquelle la languette rigide est plus large que ladite ouverture et elle comprend une aile latérale, respectivement une aile médiale, placée sous le bord latéral, respectivement le bord médial.The various objectives are achieved by providing a ski boot comprising a rigid rod consisting of a shell bottom equipped with a rigid tongue and surmounted by an articulated collar; wherein the shell bottom has a wide opening extending from the top of the stem towards the front of the foot, said opening separating a lateral edge from a medial edge, which extend parallel to one another; to the other without overlapping, and in which the rigid tongue is wider than said opening and it comprises a lateral wing, respectively a medial wing, placed under the lateral edge, respectively the medial edge.

La coque, elle-même, peut constituer en l'assemblage de différents éléments. Dans le mode de réalisation décrit ici, la coque comprend notamment un bas de coque 3, un collier articulé 4 et une languette 5. Ces trois éléments constituent l'armature rigide principale de la coque, qui est complétée par d'autres composants qui ne seront pas tous décrits en détail par la suite.The shell, itself, can constitute the assembly of different elements. In the embodiment described here, the shell comprises in particular a bottom shell 3, an articulated collar 4 and a tongue 5. These three elements constitute the main rigid armature of the shell, which is completed by other components that do not will not all be described in detail later.

Le bas de coque 3 est réalisé par moulage injection d'un polyuréthane dont le module de flexion est compris entre 200 et 1000 MPa. De manière connue, le bas de coque 3 comprend la semelle 31 et les flancs 32 de la partie basse de la tige de la chaussure. La partie haute du bas de coque est constituée par une large ouverture 33. La portion antérieure 331 de cette ouverture se prolonge jusque l'avant du pied.The bottom shell 3 is made by injection molding of a polyurethane whose flexural modulus is between 200 and 1000 MPa. In known manner, the shell bottom 3 comprises the sole 31 and the flanks 32 of the lower part of the upper of the shoe. The upper part of the shell bottom is constituted by a wide opening 33. The front portion 331 of this opening extends to the front of the foot.

La portion antérieure de l'ouverture 331 est délimitée, d'une part, latéralement par un bord latéral 322, et un bord médial 323, et d'autre part, longitudinalement par l'extrémité postérieure de la coquille 321. La coquille 321, est la partie du bas de coque qui recouvre et enveloppe le bout du pied de l'utilisateur.The front portion of the opening 331 is delimited, on the one hand, laterally by a lateral edge 322, and a medial edge 323, and on the other hand, longitudinally by the posterior end of the shell 321. The shell 321, is the part of the shell bottom that covers and wraps the end of the user's foot.

Le bord latéral 322 et le bord médial 323 ne se chevauchent pas. Ainsi, la portion antérieure de l'ouverture est largement béante et ce, même sans qu'il soit nécessaire d'exercer un effort pour écarter les flancs de la coque. Les bords latéral et médial sont sensiblement parallèles entre eux et il y a, entre eux, un écart compris entre 2 et 6 cm, cet écart constituant la largeur de l'ouverture.The lateral edge 322 and the medial edge 323 do not overlap. Thus, the anterior portion of the opening is largely gaping, even without the need to exert effort to spread the flanks of the hull. The lateral and medial edges are substantially parallel to each other and there is, between them, a gap of between 2 and 6 cm, this gap constituting the width of the opening.

Le collier 4 est fixé sur le bas de coque 3, de manière à pivoter par rapport à celle-ci autour d'un axe coïncidant avec l'axe d'articulation des malléoles. Lors des phases de marche, le collier peut alors suivre la rotation de la jambe de l'utilisateur. Le collier est également susceptible d'être fixé à l'arrière du bas de coque pour pouvoir bloquer la rotation du collier, notamment pendant les phases de ski. Le collier 4 comprend deux rabats 42, 43. Ces rabats sont de grande dimension. Ainsi, lorsque la chaussure est fermée ils viennent se reposer l'un sur l'autre et recouvrent entièrement une portion haute de la languette.The collar 4 is fixed on the shell bottom 3, so as to pivot relative thereto about an axis coinciding with the axis of articulation of the malleolus. During the walking phases, the collar can then follow the rotation of the leg of the user. The collar is also likely to be attached to the rear of the shell bottom to be able to block the rotation of the collar, especially during ski phases. The collar 4 comprises two flaps 42, 43. These flaps are large. Thus, when the shoe is closed they come to rest on one another and completely cover an upper portion of the tongue.

Comme on peut le voir à la figure 4, la languette 5 est constituée d'une pièce obtenue par injection d'une matière thermoplastique. Cette matière peut être du même type que celle utilisée pour réaliser le bas de coque. Elle est de préférence réalisée en une seule pièce depuis l'avant de la chaussure jusqu'au sommet de celle-ci afin d'assurer une bonne transmission des efforts depuis la jambe de l'utilisateur jusqu'à l'avant pied.As can be seen at figure 4 , the tongue 5 consists of a part obtained by injection of a thermoplastic material. This material may be of the same type as that used to make the shell bottom. It is preferably made in one piece from the front of the shoe to the top thereof to ensure good transmission of effort from the user's leg to the forefoot.

Au niveau de l'avant du pied, la languette comporte un élément de coopération avec des moyens de fixation au bas de coque. Dans le mode de réalisation décrit ici, il s'agit d'une ouverture 55 dans laquelle sera inséré un rivet 8. Bien entendu, tout autre moyen de fixation est envisageable sans sortir du cadre de l'invention.At the front of the foot, the tongue has a cooperating element with fixing means at the bottom of the shell. In the embodiment described here, it is an opening 55 in which a rivet 8 will be inserted. Of course, any other fastening means can be envisaged without departing from the scope of the invention.

De préférence, l'extrémité antérieure 56 de la languette, dans laquelle est réalisée l'ouverture 55, est fixée par-dessus la coquille 321. Cette caractéristique permet d'améliorer sensiblement la répartition des efforts qui sont transmis de la languette vers le bas de coque, notamment lors des phases de flexion vers l'avant, D'autre part, la fixation de la languette par le dessus permet d'économiser du volume à l'intérieur de la coque. Le volume intérieur ainsi gagné pourra être utilisé pour améliorer le confort ou l'isolation car on peut utiliser plus de couche amortissante ou d'isolation pour un même volume intérieur. Cette construction peut également permettre de diminuer le volume extérieur de la partie avant du bas de coque. Auquel cas, on dispose d'une chaussure de ski à l'esthétique améliorée car elle semble affinée par rapport aux chaussures de ski de l'art antérieur.Preferably, the front end 56 of the tongue, in which the opening 55 is made, is fixed above the shell 321. This feature significantly improves the distribution of the forces that are transmitted from the tongue downwards. hull, especially during forward bending phases, On the other hand, the attachment of the tongue from above saves volume inside the hull. The internal volume thus gained can be used to improve the comfort or the insulation because one can use more cushioning layer or insulation for the same interior volume. This construction can also reduce the external volume of the front portion of the bottom of the hull. In which case, it has a ski boot with improved aesthetics because it seems refined compared to the ski boots of the prior art.

La languette comporte également deux fentes 56 à son sommet qui servent à la fixation d'une sangle de traction 57.The tongue also has two slots 56 at its top which serve to fix a traction strap 57.

La languette comporte un plateau central 51 qui s'étend sur quasiment toute la longueur de celle-ci et qui est bordé de chaque côté par des ailes, une aile latérale 52 et une aile médiale 53. Comme on peut le voir aux figures 3 et 4, selon une coupe transversale le plateau 51 est surélevé par rapport aux ailes. D'autre part, des nervures 54, issues de la face inférieure du plateau viennent combler l'espace situé derrière le plateau de manière à offrir une surface d'appui de la languette sur le chausson intérieur qui a une courbure régulière. Les nervures 54 s'étendent également sur quasiment toute la longueur de la languette.The tongue has a central plate 51 which extends over almost the entire length of the tongue and which is bordered on each side by wings, a lateral wing 52 and a medial wing 53. As can be seen in FIG. Figures 3 and 4 , in a cross section the plate 51 is raised relative to the wings. On the other hand, ribs 54, from the underside of the tray fill the space behind the tray so as to provide a bearing surface of the tongue on the inner shoe which has a regular curvature. The ribs 54 also extend over almost the entire length of the tongue.

Les ailes de la languette sont prévues pour se placer sous les bords latéral et médial lorsque la chaussure est fermée et que les crochets de fermetures sont serrés. Il est ainsi réalisé deux chevauchement parallèles sur toute la partie basse de la languette, c'est-à-dire la partie qui se trouve au regard des bords latéral 322 et médial 323. Il y a, du côté médial de la chaussure, le chevauchement du bord médial 323 sur l'aile médiale 53 et du coté latéral, le chevauchement du bord latéral 322 sur l'aile latérale 52.The wings of the tongue are intended to be placed under the lateral and medial edges when the shoe is closed and the closures hooks are tight. It is thus realized two overlapping parallel over the entire lower part of the tongue, that is to say the part facing the side edges 322 and medial 323. There is, on the medial side of the shoe, the overlap of the medial edge 323 on the medial wing 53 and the lateral side, the overlap of the lateral edge 322 on the lateral wing 52.

Chacun des deux chevauchements parallèles a une largeur L, mesurée dans un plan transversal, comprise entre 8 et 30 mm, de préférence entre 10 et 25 mm. Ils sont d'autre part espacés l'un de l'autre d'une distance D comprise entre 25 et 60 mm.Each of the two parallel overlaps has a width L, measured in a transverse plane, of between 8 and 30 mm, preferably between 10 and 25 mm. They are on the other hand spaced from each other by a distance D between 25 and 60 mm.

Structurellement, lorsque la chaussure est fermée et correctement serrée, c'est-à-dire typiquement en phase de ski, les chevauchements constituent une paire de deux renforts parallèles qui commencent dans la partie haute du bas de coque et se prolongent jusque dans l'avant pied. Cette paire de renfort a pour effet de rigidifier la chaussure l'ensemble du bas de coque.Structurally, when the boot is closed and properly tightened, that is, typically in the ski phase, the overlaps constitute a pair of two parallel reinforcements which begin in the upper part of the shell bottom and extend into the before foot. This pair of reinforcement has the effect of stiffening the shoe all of the bottom shell.

Au-dessus du bas de coque, du fait du chevauchement des rabats 42 et 43 du collier 4, celui-ci ceinture complètement le bas de jambe de l'utilisateur et recouvre de ce fait la languette 5. Cette construction a pour effet de maintenir la languette bien en place à l'intérieur du bas de coque, lorsque le skieur fléchit la jambe vers l'avant et que la pression du tibia sur la languette a tendance à faire basculer cette dernière vers l'avant.Above the bottom of the shell, because of the overlap of the flaps 42 and 43 of the collar 4, it completely surrounds the lower leg of the user and thus covers the tongue 5. This construction has the effect of maintaining the tongue well in place inside the bottom of the hull, when the skier bends the leg forward and the pressure of the shin on the tongue tends to tilt the latter forward.

En outre, il est à noter que le plateau central 51 ainsi que les nervures 64 contribuent, également à rigidifier la chaussure, notamment car ils évitent les déformations de la languette 5 lorsque le skieur fléchit vers l'avant.In addition, it should be noted that the central plate 51 and the ribs 64 also contribute to stiffening the boot, especially since they avoid deformations of the tongue 5 when the skier bends forward.

Un panneau souple 6 est fixé sur le bord latéral et le bord médial de l'ouverture 33. Il est de préférence placé sur la face extérieure du bas de coque et passe en dessous de la languette. Il est ainsi réalisé un soufflet 61 qui garantit l'étanchéité de la chaussure. La neige et l'eau ne peuvent pas pénétrer dans la chaussure, même lorsque la chaussure n'est pas fermée et que les deux bords latéraux sont écartés l'un de l'autre pour faciliter l'introduction du pied de l'utilisateur.A flexible panel 6 is attached to the lateral edge and the medial edge of the opening 33. It is preferably placed on the outer face of the shell bottom and passes below the tongue. It is thus realized a bellows 61 which guarantees the tightness of the shoe. The snow and water can not penetrate the shoe, even when the shoe is not closed and the two side edges are spaced from each other to facilitate the introduction of the foot of the user.

La figure 6 montre une vue intérieure partielle de la languette 5. On peut voir que le soufflet 61 présent dans la partie basse du panneau souple 6 se prolonge vers le haut par un tablier 62. Le tablier 62 à sensiblement la forme d'un triangle. Au sommet de ce tablier 62, sont prévus des moyens de fixation de ce-dernier sur la languette 5. En l'occurrence, dans le mode de réalisation décrit, il s'agit d'un rivet principal 63. Pour la fixation de la languette 6 au panneau souple 6, on peut éventuellement associer le rivet principal 63 à deux rivets latéraux 64.The figure 6 shows a partial internal view of the tongue 5. It can be seen that the bellows 61 present in the lower part of the flexible panel 6 is extended upwardly by an apron 62. The apron 62 has substantially the shape of a triangle. At the top of this apron 62, there are provided means for fixing the latter on the tongue 5. In this case, in the embodiment described, it is a main rivet 63. For fixing the tongue 6 to the flexible panel 6, one can optionally associate the main rivet 63 with two side rivets 64.

La fixation du tablier 62 sur la languette par les moyens de fixation principaux est réalisée dans la demi-portion supérieure de la languette, au-dessus de la zone correspondant au cou-de-pied. Les autres moyens de fixation constitués dans le cas d'espèce par les deux rivets latéraux sont placés plus bas sur la languette, approximativement dans la zone de courbure maximale de celle-ci. Il s'agit de la zone où, à partir de l'avant pied, la languette passe d'une orientation principalement horizontale, voire légèrement inclinée, à une orientation principalement verticale.The attachment of the apron 62 on the tongue by the main fastening means is performed in the upper half-portion of the tongue, above the area corresponding to the instep. The other fixing means constituted in this case by the two lateral rivets are placed lower on the tongue, approximately in the maximum curvature zone thereof. This is the area where, starting from the forefoot, the tongue moves from a mainly horizontal orientation, even slightly inclined, to a mainly vertical orientation.

De préférence, le panneau souple 6 est peu ou pas expansible. Ainsi, le panneau souple fait office de frein pour la languette 5 lorsque l'utilisateur tire sur la sangle de traction 57 pour écarter cette dernière. C'est ce qui permet d'éviter que la totalité de la longueur des ailes de la languette ne passent au-dessus des bords latéral et médial 322, 323. Bien entendu, la longueur du tablier 62 est choisie pour que lors de l'ouverture maxi de la languette, il y ait toujours quelque part sur la longueur des ailes un contact frontal entre la tranche des bords latéral et médial et la tranche des ailes. Ainsi, il est aisé de replacer la languette sous les bords latéral et médial, pour refermer la chaussure.Preferably, the flexible panel 6 is little or not expandable. Thus, the flexible panel acts as a brake for the tongue 5 when the user pulls on the traction strap 57 to spread it. This prevents the entire length of the wings of the tongue from passing over the lateral and medial edges 322, 323. Of course, the length of the apron 62 is chosen so that when the maximum opening of the tongue, there is always somewhere along the length of the wings a frontal contact between the edge of the lateral and medial edges and the edge of the wings. Thus, it is easy to replace the tongue under the lateral and medial edges, to close the shoe.

La figure 4 montre en coupe, le bas de coque et la languette lorsque les crochets 37 sont desserrés ou ouverts. Les flancs 32 du bas de coque retrouvent alors leur position à l'état libre. Pour pouvoir faciliter l'introduction de son pied dans la chaussure, l'utilisateur peut accroitre l'ouverture de celle-ci en exerçant une traction vers le haut et vers l'avant sur la sangle 57. Par suite, les bords de la languette viennent s'appuyer sur les bords latéral et médial 322, 323 et les écarter l'un de l'autre.The figure 4 shows in section, the shell bottom and the tongue when the hooks 37 are loosened or open. The flanks 32 of the hull bottom then find their position in the free state. To be able to facilitate the introduction of his foot into the shoe, the user can increase the opening thereof by exerting a pull upward and forward on the strap 57. As a result, the edges of the tongue come to rest on the lateral and medial edges 322, 323 and separate them from each other.

La figure 4A montre en coupe une variante de réalisation de l'invention. Pour faciliter la compréhension, la position effective de la coupe de la figure 4A est repérée sur la figure 4. Dans cette variante, des moyens supplémentaires sont aménagés pour empêcher la languette 5 de sortir de son emplacement Ces moyens de rétention 9 de la languette 5 consistent en une bande 91 fixée d'une part au bord latéral 322 et d'autre part à la languette 5. La fixation des deux extrémités de la bande peut être faite par tout moyen approprié, rivet, collage, couture, vis/écrou.The Figure 4A shows in section an alternative embodiment of the invention. To facilitate understanding, the actual position of the cup of the Figure 4A is spotted on the figure 4 . In this variant, additional means are provided to prevent the tongue 5 from leaving its location. These retention means 9 of the tongue 5 consist of a band 91 fixed on the one hand to the lateral edge 322 and on the other hand to the tongue 5. Fixing both ends of the band can be made by any suitable means, rivet, gluing, seam, screw / nut.

Dans la réalisation présentée ici, un orifice 521 est ménagé sur la languette 5 entre le plateau 51 et l'aile latérale 52. La bande 91 est fixée sur le bord latéral 322, puis elle est glissée à travers l'orifice 521. Elle est ensuite fixée sous la languette 5. Le choix de la longueur de la bande 91 est fait judicieusement de telle manière que l'amplitude du mouvement relatif entre le bord latéral 322 et la languette 5 soit limitée. Ainsi, il est impossible que l'aile latérale 52 passe au-dessus du bord latéral. La présence de moyens de rétention 9 sur le côté latéral/ou médial uniquement suffit à empêcher la partie basse de la languette de s'extraire de sa position normale sous les bords latéral 322 et médial 323.In the embodiment presented here, an orifice 521 is formed on the tongue 5 between the plate 51 and the lateral flange 52. The band 91 is fixed on the lateral edge 322, then it is slid through the orifice 521. It is The choice of the length of the band 91 is judiciously made so that the amplitude of the relative movement between the lateral edge 322 and the tongue 5 is limited. Thus, it is impossible for the side wing 52 to pass over the side edge. The presence of retention means 9 on the lateral / medial side only is sufficient to prevent the lower part of the tongue from being pulled out of its normal position under the lateral 322 and medial 323 edges.

Avantageusement les moyens de rétention 9 pourront être placés sous l'un des crochets 37 de manière à être pratiquement invisibles.Advantageously, the retention means 9 may be placed under one of the hooks 37 so as to be virtually invisible.

La figure 5 montre une vue en perspective du chausson intérieur de la chaussure de l'invention. Comme la plupart des chaussons prévus pour les chaussures de ski rigides, il est constitué par un assemblage de différents panneaux souples qui peuvent être des tissus, des nappes non-tissés, des films de matière plastique et des panneaux souples de mousse. D'autre part, il comprend une longue portion avant 21 sans ouverture, tandis que deux fentes verticales 22, 23 prennent leur origine au niveau du cou-de-pied et s'étendent jusqu'au sommet du chausson. Les deux fentes verticales 22, 23 délimitent une portion languette 25 de chausson.The figure 5 shows a perspective view of the boot inside the shoe of the invention. Like most slippers provided for rigid ski boots, it is constituted by an assembly of various flexible panels which may be fabrics, nonwoven webs, plastic films and flexible foam panels. On the other hand, it comprises a long front portion 21 without opening, while two vertical slots 22, 23 take their origin in the instep and extend to the top of the liner. The two vertical slots 22, 23 delimit a tongue portion 25 of liner.

Le chausson ne comporte pas, comme c'est le cas dans les chaussons pour chaussures de ski alpin performantes modernes, de plaque rigide de répartition. En effet, la surface extérieure d'une portion frontale 24 du chausson est confectionnée à partir de matériaux souples. La portion frontale 24 correspond à la portion du chausson qui se trouve sous la languette 5, lorsque le chausson est inséré dans le bas de coque.The slipper does not have, as is the case in slippers for modern high-performance alpine ski boots, rigid distribution plate. Indeed, the outer surface of a front portion 24 of the liner is made from flexible materials. The front portion 24 corresponds to the portion of the liner which is under the tongue 5, when the liner is inserted into the bottom of the shell.
