Abstract

A safety binding of a boot on a ski, which comprises two lateral clamps (1) displaceably mounted under the effect of a resilient member between a closed service position, in which the clamps cooperate with the sole of the boot, and an open position. Each lateral clamp is pivoted at the end of an arm (12) on a pivot axle (14) perpendicular to the plan of the ski, said arm being itself pivotaly mounted by its other end on an axle (13) perpendicular to said plan of the ski.

Description

La présente invention se rapporte à une fixation de sécurité d'une chaussure sur un ski, et plus particulièrement à une fixation de sécurité comportant des mâchoires latérales destinées à maintenir en position de service la chaussure sur un ski, ainsi qu'à une chaussure destinée à coopérer avec cette fixation.The present invention relates to a safety binding of a boot on a ski, and more particularly to a safety binding comprising lateral jaws intended to hold the boot in the service position, as well as to a boot intended to cooperate with this fixation.

Le principe des fixation à mâchoires latérales est connu depuis plusieurs années, notamment par les brevets FR 1.411.638 et FR 2.021.237, mais n'a jusqu'à présent pas abouti à des réalisations sufisamment fiables pour être commercialisées. Des améliorations ont été apportées par exemple pour améliorer le dégagement de la chaussure en cas d'ouverture de sécurité de la fixation, comme décrit dans le brevet FR 2.420.358, ou bien pour améliorer le fonctionnement même de ce type de fixation et leur donner une fiabilité plus grande en cas de chute, comme divulgué dans le brevet CH 645.030 et les demandes de brevets EP 0 084 813 et EP o 085 313 de la même titulaire.The principle of fastening with lateral jaws has been known for several years, in particular by the patents FR 1,411,638 and FR 2,021,237, but until now has not resulted in sufficiently reliable embodiments to be marketed. Improvements have been made for example to improve the clearance of the shoe in the event of the security opening of the binding, as described in patent FR 2,420,358, or else to improve the very functioning of this type of binding and give them greater reliability in the event of a fall, as disclosed in patent CH 645,030 and patent applications EP 0 084 813 and EP o 085 313 by the same owner.

Les fixations à mâchoires latérales en général et celles du type décrit dans les deux derniers documents précités en particulier présentent en outre les inconvénients suivants. Les mâchoires latérales comportent des formes en pente ou en coin correspondant à une empreinte pratiquée dans la semelle de la chaussure ou rapportée sur cette semelle. Ces formes sont à 3 dimensions, puisque destinées à maintenir la chaussure latéralement, longitudinalement et verticalement. Ces formes sont donc compliquées et nécessitent une très grande précision.Fasteners with side jaws in general and those of the type described in the last two documents mentioned above in particular have the following disadvantages. The lateral jaws have sloping or wedge-shaped shapes corresponding to an imprint made in the sole of the shoe or attached to this sole. These shapes are 3-dimensional, since they are intended to hold the shoe laterally, longitudinally and vertically. These forms are therefore complicated and require very high precision.

En outre, la faible longueur d'accrochage dans de telles fixations entre les mâchoires latérales et l'empreinte par rapport à la longueur de la chaussure constitue un grave inconvénient. En effet, des imprécisions de quelques dixièmes de mm dans les formes d'accrochage des mâchoires ou de l'empreinte se traduiront par des jeux de plusieurs mm aux extrémités de la chaussure, ce qui rend la fixation difficilement utilisable en pratique. C'est la raison pour laquelle, avec de tels systèmes, l'utilisation d'une empreinte directement de moulage plastique est pratiquement impossible, les tolérances du moulage plastique n'arrivant pas à garantir le degré de précision nécessaire.In addition, the short hooking length in such bindings between the lateral jaws and the imprint relative to the length of the shoe is a serious drawback. Indeed, inaccuracies of a few tenths of mm in the forms of attachment of the jaws or of the imprint will result in play of several mm at the ends of the shoe, which makes the fixing difficult to use in practice. This is the reason why, with such systems, the use of an impression directly from plastic molding is practically impossible, the tolerances of plastic molding failing to guarantee the necessary degree of precision.

De plus, l'introduction de neige, glace ou autres éléments tels que graviers entre la semelle de la chaussure et la plaque supérieure de la fixation, modifie les formes géométriques d'accrochage et crée des jeux très importants aux extrémités de la chaussure, ce qui conduit à une utilisation pratique non satisfaisante et peu fiable.In addition, the introduction of snow, ice or other elements such as gravel between the sole of the shoe and the upper plate of the binding, modifies the geometrical shapes of attachment and creates very large clearances at the ends of the shoe, this which leads to unsatisfactory and unreliable practical use.

Le but de la présente invention consiste donc à remédier aux inconvénients précités des fixations à mâchoires latérales connues, de manière à garantirla stabilité d'accrochage de la chaussure sur la fixation dans toutes les conditions défavorables, c'est-à-dire même lorsque des éléments extérieurs, tels que neige, glace ou graviers, se trouvent entre les parties chaussure et fixation, ceci grâce à une auto-compensation des jeux, celle-ci permettant également d'augmenter très fortement la longueur d.'accrochage et de garantir ainsi une meilleure stabilité.The object of the present invention therefore consists in remedying the aforementioned drawbacks of fastenings with known lateral jaws, so as to guarantee the stability of attachment of the shoe to the binding under all unfavorable conditions, that is to say even when external elements, such as snow, ice or gravel, are located between the shoe and binding parts, this thanks to a self-compensation of the clearances, this also making it possible to very greatly increase the length of attachment and thus guarantee better stability.

La fixation de sécurité selon l'invention, qui vise à atteindre le but précité, comporte deux mâchoires latérales montées déplaçables sous l'action d'un organe élastique entre une position de service fermée, dans laquelle ces mâchoires coopèrent avec la semelle de la chaussure, et une position ouverte, caractérisée par le fait que chaque mâchoire latérale est articulée à l'extrémité d'un bras sur un pivot perpendiculaire au plan du ski, ce bras étant lui-même monté pivotant par son autre extrémité sur un axe perpendiculaire audit plan du ski.The safety binding according to the invention, which aims to achieve the aforementioned aim, comprises two lateral jaws mounted movable under the action of an elastic member between a closed service position, in which these jaws cooperate with the sole of the shoe , and an open position, character laughed at by the fact that each lateral jaw is articulated at the end of an arm on a pivot perpendicular to the plane of the ski, this arm being itself pivotally mounted by its other end on an axis perpendicular to said plane of the ski.

Selon une forme d'exécution préférée, chaque mâchoire comporte un doigt d'accrochage antérieur et un doigt d'accrochage postérieur, ces doigts faisant avec le plan du ski un angle compris respectivement entre 20 et 35° pour le doigt antérieur et entre 40 et 50° pour le doigt postérieur.According to a preferred embodiment, each jaw comprises a front hooking finger and a rear hooking finger, these fingers making an angle with the plane of the ski of between 20 and 35 ° respectively for the front finger and between 40 and 50 ° for the posterior finger.

Un second objet de cette invention consiste en une chaussure destinée à être fixée sur un ski au moyen de la fixation de sécurité définie ci-dessus, et qui est caractérisée par le fait qu'elle comporte une semelle dont la partie médiane comprend une empreinte présentant de chaque côté deux formations d'accrochage destinées à coopérer en position de service avec les mâchoires latérales de la fixation, une première formation d'accrochage antérieure présentant une face inclinée vers l'intérieur et vers le haut et faisant avec le plan de la semelle un angle compris entre 20 et 35°, et une seconde formation d'accrochage postérieure présentant une face inclinée vers l'intérieur et vers le haut et faisant avec le plan de la semelle un angle compris entre 40 et 50°.A second object of this invention consists of a shoe intended to be fixed on a ski by means of the safety binding defined above, and which is characterized in that it comprises a sole, the middle part of which comprises an imprint having on each side two attachment formations intended to cooperate in the service position with the lateral jaws of the binding, a first anterior attachment formation having a face inclined inward and upward and forming with the plane of the sole an angle between 20 and 35 °, and a second posterior attachment formation having a face inclined inward and upward and forming an angle of between 40 and 50 ° with the plane of the sole.

En référence tout d'abord aux figures 1 à 3, la forme d'exécution de l'invention telle qu'illustrée partiellement consiste en une fixation de sécurité fixée sur la surface supérieure d'un ski S et comportant deux mâchoires latérales 1. En position de service fermée, les mâchoires latérales 1 enserrant par leurs griffes respectivement antérieures 2 et postérieures 2' les rebords latéraux de la portion médiane 3 de la se- ;melle d'une chaussure de ski C, plus particulièrement les empreintes correspondantes que présentent ces rebords latéraux. Comme illustré, les griffes ou doigts d'accrochage antérieurs 2 font avec le plan du ski un angled d'environ 30°, alors que les doigts d'accrochage postérieurs 2' font avec ce plan un angle o(' d'environ 45°.Referring firstly to FIGS. 1 to 3, the embodiment of the invention as partially illustrated consists of a safety binding fixed to the upper surface of a ski S and comprising two lateral jaws 1.

Dans la position ouverte (non montrée), les mâchoires latérales 1 ne maintiennent par contre plus entre elles la portion médiane 3 de la semelle de la chaussure C. Le déplacement entre les deux positions respectivement fermée et ouverte décrites ci-dessus est provoqué par l'action d'un organe élastique d'accumulation d'énergie (non montré) disposé de préférence en arrière des mâchoires 1, et par l'entremise par exemple d'une tringle 4 coulissant longitudinalement.In the open position (not shown), the on the other hand, the lateral jaws 1 no longer hold the middle portion 3 of the sole of the shoe between them. The movement between the two positions, respectively closed and open, described above, is caused by the action of an elastic accumulation member. energy (not shown) preferably arranged behind the jaws 1, and by means of for example a rod 4 sliding longitudinally.

L'extrémité antérieure de cette tringle d' actionnement 4, dont l'autre extrémité coopère avec l'organe élastique, est reliée aux mâchoires 1 au moyen de deux paires de biellettes 5,6. Chaque paire de biellettes comprend une première biellette droite 5 articulée d'un côté à l'extrémité de la tringle 4 et de l'autre côté sur une seconde biellette coudée 6, au moyen de tétons d'articulation 7, 8. Cette seconde biellette est montée pivotante au niveau de sa portion coudée sur un pivot vertical 9 solidaire de la surface supérieure du ski S et présente une ouverture allongée 10 avec laquelle coopère un téton d'articulation 11 solidaire de la partie horizontale de la mâchoire 1, de manière à permettre l'ouverture latérale de celle-ci sous l'effet d'un mouvement de translation de la tringle 4 vers l'avant. Ce mouvement est possible par le fait que chaque mâchoire 1 est portée par un bras 12 dont l'extrémité postérieure est montée pivotante sur un pivot vertical 13.The front end of this actuating rod 4, the other end of which cooperates with the elastic member, is connected to the jaws 1 by means of two pairs of rods 5,6. Each pair of links comprises a first straight link 5 articulated on one side at the end of the rod 4 and on the other side on a second bent link 6, by means of articulation pins 7, 8. This second link is pivotally mounted at its bent portion on a vertical pivot 9 secured to the upper surface of the ski S and has an elongated opening 10 with which a hinge pin 11 cooperates secured to the horizontal part of the jaw 1, so as to allow the lateral opening thereof under the effect of a translational movement of the rod 4 towards the front. This movement is possible by the fact that each jaw 1 is carried by an arm 12 whose rear end is pivotally mounted on a vertical pivot 13.

Plus particulièrement, chaque mâchoire 1 est articulée sur un bras 12 au moyen d'un téton d'articulation 14 vertical; le pivotement de la mâchoire 1 à l'extrémité du bras 12 est de plus limité par un épaulement 15 que présente ladite mâchoire à son extrémité arrière, cet épaulement 15 venant en butée contre le bras 12 en ouverture de la fixation et ceci après rattrapage d'un jeu de fonctionnement.More particularly, each jaw 1 is articulated on an arm 12 by means of a vertical hinge pin 14; the pivoting of the jaw 1 at the end of the arm 12 is further limited by a shoulder 15 which said jaw has at its rear end, this shoulder 15 abutting against the arm 12 at the opening of the binding and this after catching up of an operating clearance.

Les figures 4 à 7 illustrent la même fixation que celle des figures 1 à 3, mais dans le cas où une couche de neige N, de glace ou autres matières (terre, gravier,etc.) s'est introduite lors du chaussage de la fixation, entre la plaque de base 16 de celle-ci et la semelle de la chaussure C. Cette épaisseur non souhaitée de neige N tend à soulever de quelques mm la chaussure C, de telle sorte que les griffes postérieures 2' des mâchoires 1 sont légèrement êcarT tées vers l'extérieur par la pente que présente la partie médiane 3 de la semelle de la chaussure, ce qui provoque le pivotement des mâchoires 1 sur le bras 12 et un déplacement vers l'extérieur des tétons d'articulation 14, les mâchoires 1 formant alors avec les bras 12 un angle obtu.Figures 4 to 7 illustrate the same binding as that of Figures 1 to 3, but in the case where a layer of snow N, ice or other matter (earth, gravel, etc.) was introduced during the fitting of the attachment, between the base plate 16 thereof and the sole of the shoe C. This unwanted thickness of snow N tends to lift the boot C by a few mm, so that the rear claws 2 ′ of the jaws 1 are slightly spread outwards by the slope presented by the middle part 3 of the sole of the shoe, which causes the jaws 1 to pivot on the arm 12 and an outward movement of the articulation pins 14, the jaws 1 then forming with the arms 12 an obtuse angle.

Ainsi, même en présence d'une épaisseur in- désirée de neige N sous la chaussure C, les griffes 2,2' des mâchoires latérales 1 restent toujours en contact avec les empreintes correspondantes de la partie médiane 3 de la semelle de la chaussure C, et la fixation de celle-ci sur le ski S est donc assurée également dans la situation précitée. La qualité du serrage et du centrage des griffes sur l'empreinte devient ainsi indépendante des surépaisseurs dues à la présence d'éléments extérieurs et de l'emplacement de ceux-ci.Thus, even in the presence of an undesired thickness of snow N under the boot C, the claws 2,2 ′ of the lateral jaws 1 always remain in contact with the corresponding imprints of the central part 3 of the sole of the boot C , and the fixing thereof on the ski S is therefore also ensured in the aforementioned situation. The quality of the clamping and centering of the claws on the impression thus becomes independent of the extra thicknesses due to the presence of external elements and their location.

L'invention s'applique bien entendu à toutes fixation du type décrit en référence aux dessins annexés, quel que soit le système mécanique commandant l'ouverture et la fermeture des mâchoires latérales. Elle s'applique notamment particulièrement bien aux fixations décrites dans les documents antérieurs de la même titulaire mentionnés dans la partie introductive.The invention applies of course to any attachment of the type described with reference to the accompanying drawings, whatever the mechanical system controlling the opening and closing of the side jaws. It applies in particular particularly well to the fixings described in the previous documents of the same holder mentioned in the introductory part.

Plus particulièrement, le système mécanique d'actionnement peut comprendre une tringle telle que celle illustrée sur les dessins annexés, c'est-à-dire coulissant longitudinalement, dont l'extrémité antérieure est reliée aux mâchoires latérales par l'entremise de deux paires de biellettes, et dont l'autre extrémité coopère avec une bascule soumise à l'action d'un organe élastique, de telle sorte que cette bascule présente deux positions stables correspondant aux positions respectivement ouverte et fermée des mâchoires.More specifically, the mechanical system actuator may include a rod such as that illustrated in the accompanying drawings, that is to say sliding longitudinally, the anterior end of which is connected to the lateral jaws by means of two pairs of rods, and the another end cooperates with a rocker subjected to the action of an elastic member, so that this rocker has two stable positions corresponding to the respectively open and closed positions of the jaws.

Un tel système est présent dans la réalisation illustrée sur les figures 9 et 10, qui comporte en outre une talonnière servant d'élément serre-semelle et dont le mécanisme et le fonctionnement sont analogues à ceux décrits dans la demande co-pendante EP 84.103485.3 de la même titulaire.Such a system is present in the embodiment illustrated in FIGS. 9 and 10, which further comprises a heel piece serving as a sole-clamping element and the mechanism and operation of which are similar to those described in co-pending application EP 84.103485. 3 from the same licensee.

Dans cette réalisation, un seul organe élastique d'accumulation d'énergie, constitué par exemple par un ressort 17, actionne à la fois les mâchoires latérales 1 et un élément serre-semelle 18 qui sont couplés mécaniquement l'un à l'autre, ici par l'entremise notamment de la tringle d'actionnement 4, de telle sorte que l'ouverture, respectivement la fermeture, de l'un des deux dispositifs provoque l'ouverture, respectivement la fermeture de l'autre, et réciproquement.In this embodiment, a single elastic energy storage member, constituted for example by a spring 17, actuates both the side jaws 1 and a sole clamp element 18 which are mechanically coupled to each other, here through in particular the actuating rod 4, so that the opening, respectively closing, of one of the two devices causes the opening, respectively the closing of the other, and vice versa.

Le ressort 17 est monté dans un boîtier 19, fixé sur la surface supérieure du ski S, et sur une tige téléscopique formée de deux parties 20,20' coulissant l'une dans l'autre, cette tige 20,20' étant montée pivotante par son extrémité arrière sur un axe transversal 21 fixé dans la paroi du boîtier 19. L'extrémité avant de cette tige téléscopique 20,20' est articulée au centre d'une bielette droite 22 (axe transversal d' articulation 23), celle-ci étant à son tour articulée par son extrémité arrière sur un axe transversal 24 sur lequel est également articulée une extrémité d'une biellette coudée 25 servant d'organe "bascule". Cette biellette coudée 25 est montée pivotante par sa portion coudée sur un axe transversal 26 fixé dans les parois du boîtier 19, coopère par son autre extrémité 27 avec une fourchette 28 que présente l'extrémité arrière de la tringle d'actionnement 4. Quant à l'autre extrémité de la biellette droite 22, elle est articulée avec jeu sur un axe transversal 29 solidaire d'un levier d'actionnement 30, lui-même monté pivotant sur un axe transversal 31 fixé dans les parois du boîtier 19, ce levier 30 présentant dans sa portion antérieur l'élément serre-semelle 18, appuyant, dans la position de service illustrée, sur un épaulement supérieur T du talon de la chaussure de ski C. Sur les figures 9 et 10 sont encore représentés d'une part un "stopper" ou frein comportant deux bras 32 montés pivotants sur un axe transversal 33, et d'autre part un organe de chaussage automatique 34 actionné par le talon de la chaussure de ski et coopérant pour fermer la fixation avec l'organe "bascule" 25.The spring 17 is mounted in a housing 19, fixed on the upper surface of the ski S, and on a telescopic rod formed by two parts 20,20 'sliding one inside the other, this rod 20,20' being pivotally mounted by its rear end on a transverse axis 21 fixed in the wall of the housing 19. The front end of this telescopic rod 20,20 'is articulated in the center of a straight rod 22 (transverse axis of articulation 23), this- this being in turn articulated by its rear end on a transverse axis 24 on which is also articulated one end of a bent rod 25 serving as a "rocker" member. This bent rod 25 is pivotally mounted by its bent portion on a transverse axis 26 fixed in the walls of the housing 19, cooperates by its other end 27 with a fork 28 that has the rear end of the actuating rod 4. As for the other end of the straight link 22, it is articulated with clearance on a transverse axis 29 secured to an actuating lever 30, itself pivotally mounted on a transverse axis 31 fixed in the walls of the housing 19, this lever 30 having in its front portion the sole clamp element 18, pressing, in the illustrated service position, on an upper shoulder T of the heel of the ski boot C. In FIGS. 9 and 10 are also shown on the one hand a "stop" or brake comprising two arms 32 pivotally mounted on a transverse axis 33, and on the other hand an automatic boot member 34 actuated by the heel of the ski boot and cooperating to close the binding with the "rocker" member "25.

Dans la position de service illustrée sur la figure 10, les doigts d'accrochage avant 2 et arrière 2' coopèrent respectivement avec des formations d'accrochage correspondantes 35,35' que présente l'empreinte 3 située dans la partie médiane de la semelle de la chaussure de ski C. Les deux doigts d'accrochage antérieurs 2, faisant un angle compris entre 20 et 35° avec le plan du ski, garantissent le fonctionnement de la fixation lors d'un dégagement arrière, alors que les doigts d'accrochage postérieurs 2', faisant avec le plan du ski un angle de 40 à 50°, garantissent eux le fonctionnement de la fixation en cas de dégagement avant.In the service position illustrated in FIG. 10, the front hooking fingers 2 and rear 2 ′ cooperate respectively with corresponding hooking formations 35.35 ′ which has the recess 3 located in the middle part of the sole of the ski boot C. The two front gripping fingers 2, making an angle of between 20 and 35 ° with the plane of the ski, guarantee the functioning of the binding during rear release, while the gripping fingers rear 2 ', making an angle of 40 to 50 ° with the ski plane, guarantee the functioning of the binding in the event of front clearance.

D'une manière générale, les mâchoires et par co: c;équent les doigts d'accrochage sont sous l' action du même et unique système de tension. La différence entre les angles des doigts arrières et avants, et par conséquent la différence d'angle des parties empreintes de la chaussure respectives, est indispensable pour le bon fonctionnement de la fixation. En effet, le couple de dégagement en chute arrière doit être plus important que le couple de dégagement en chute avant. Il est admis en effet que le couple "chute arrière" doit être entre 25 et 35% plus élevé par rapport au couple "chute avant". L'accrochage à mâchoires latérales étant central, les différences d'angle des doigts avants et arrières sont déterminés par les différences de couples, chute avant et arrière, nécessaires au bon fonctionnement de dégagement de la fixation.Generally speaking, the jaws and, therefore, the attachment fingers are under the action of the same and unique tension system. The difference between the angles of the rear and front fingers, and therefore the difference in angle of the imprinted parts of the respective shoe, is essential for the proper functioning of the binding. Indeed, the release torque in rear fall must be greater than the release torque in front fall. It is indeed accepted that the "rear fall" torque must be between 25 and 35% higher compared to the "front fall" couple. As the attachment to the side jaws is central, the differences in angle of the front and rear fingers are determined by the differences in torques, front and rear drop, necessary for the correct release of the binding.

Sur les mâchoires, entre les doigts avant 2 et arrière 2', une ouverture est pratiquée. Lors du fonctionnement en torsion et à partir de la limite de dégagement, la partie empreinte 3 de la semelle de la chaussure sort des doigts et entre dans l'ouverture, ce qui permet un dégagement complet de torsion sans nécessiter un déplacement vertical.On the jaws, between the front 2 and rear 2 ′ fingers, an opening is made. When operating in torsion and from the clearance limit, the imprint portion 3 of the sole of the shoe exits from the fingers and enters the opening, which allows complete release of torsion without requiring vertical displacement.

Le système de tension des mâchoires (axe 11) est placé approximativement à mi-distance dans le sens longitudinal entre les doigts avant 2 et arrière 2' afin de garantir une répartition égale des efforts de tension sur ces deux doigts.The jaw tensioning system (axis 11) is placed approximately halfway in the longitudinal direction between the front 2 and rear 2 ′ fingers in order to guarantee an equal distribution of the tension forces on these two fingers.

Comme on l'a déjà décrit, la mâchoire est composée de deux parties articulées 1, 12. Dans le cas d'un dégagement de torsion par exemple, le système fonctionne normalement et il y a pivotement de toute la mâchoire autour de l'axe 13. Ce système auto-compensé agit avec l'articulation (axe 14). En cas d'introduction de neige, glace ou autres éléments extérieurs, les différences de hauteur sont automatiquement compensées par la possibilité de la partie mâchoire avant de pivoter autour de l'axe 14 et par conséquent de maintenir constamment les doigts avant 2 et arrière 2' en contact avec les formations d'accrochage respectivement avant et arrière 35, 35' de l'empreinte médiane 3 de la semelle de la chaussure.As already described, the jaw is composed of two articulated parts 1, 12. In the case of a release of torsion for example, the system operates normally and there is pivoting of the entire jaw around the axis 13. This self-compensating system works with the joint (axis 14). In the event of snow, ice or other external elements being introduced, the height differences are automatically compensated for by the possibility of the jaw part before pivoting around the axis 14 and therefore constantly keeping the front fingers 2 and rear 2 'in contact with the hooking formations respectively front and rear 35, 35' of the central imprint 3 of the sole of the shoe.

Sur les figures 11 à 15 est illustrée plus en détail mais partiellement, une forme d'exécution de la semelle d'une chaussure de ski destinée à coopérer avec une fixation de sécurité selon l'invention.In Figures 11 to 15 is illustrated in more detail but partially, an embodiment of the sole of a ski boot intended to cooperate with a safety binding according to the invention.

Comme on l'a déjà vu précédemment, en référence à la figure 10, la semelle présente une empreinte 3 dans sa portion médiane, qui comporte de chaque côté deux formations d'accrochage, respectivement antérieure 35 et postérieure 35'. Ces formations d'accrochage 35, 35' sont plus particulièrement formées par des faces inclinées vers l'intérieur de la semelle et vers le haut, et faisant avec le plan de la semelle un angle respectivement β d'environ 30° et β d'environ 45° (figures 12 et 13). Ces formations sont donc, comme décrit précédemment, destinées à coopérer en position de service avec les doigts d'accrochage des mâchoires latérales. Dans l'axe longitudinal de la semelle l'empreinte 3 est reliée aux parties avant et arrière de la semelle par une nervure 36, 36' présentant en coupe (figures 14 et 15) la forme d'un V ou d'un U.As already seen previously, with reference to FIG. 10, the sole has an imprint 3 in its median portion, which comprises on each side two hooking formations, respectively anterior 35 and posterior 35 '. These attachment formations 35, 35 ′ are more particularly formed by faces inclined towards the inside of the sole and upwards, and forming with the plane of the sole an angle β of approximately 30 ° and β d 'respectively. about 45 ° (Figures 12 and 13). These formations are therefore, as described above, intended to cooperate in the service position with the hooking fingers of the lateral jaws. In the longitudinal axis of the sole, the imprint 3 is connected to the front and rear parts of the sole by a rib 36, 36 'having in section (Figures 14 and 15) the shape of a V or a U.

L'empreinte 3 avec les formations d'accrochage 35,35' et les nervures de liaison 36, 36' peut être réalisée soit de fabrication par moulage avec le reste de la semelle, soit sous la forme d'un élément destiné à être rapporté sur une semelle existante.The impression 3 with the hooking formations 35, 35 ′ and the connecting ribs 36, 36 ′ can be produced either by manufacturing by molding with the rest of the sole, or in the form of an element intended to be attached. on an existing sole.

Dans la plupart des fixations de ski connues, la présence de neige ou de glace au-dessous de la semelle de la chaussure peut provoquer une surcharge sur le système mécanique d'actionnement, et conduire ainsi à la nécessité d'une force supérieure pour provoquer l'ouverture de ladite fixation en cas de chute par exemple. Or, ceci est un inconvénient qui peut empêcher la commercialisation d'une fixation pour des raisons de sécurité. Par contre, avec la fixation selon l'invention, d'une part il est possible au skieur de chausser ses skis même dans une situation difficile (par exemple dans la neige profonde), sans avoir besoin au préalable de nettoyer complètement le dessous de la semelle de sa chaussure, et d'autre part même en présence d'une couche de neige ou de glace sous cette chaussure, il n'y a aucune surcharge, donc aucun effort supplémentaire nécessaire pour provoquer l'ouverture de la fixation en cas de chute par exemple.In most known ski bindings, the presence of snow or ice below the sole of the boot can cause an overload on the mechanical actuation system, and thus lead to the need for a higher force to cause the opening of said binding in the event of a fall, for example. However, this is a drawback which can prevent the marketing of a fixation for security reasons. On the other hand, with the binding according to the invention, on the one hand it is possible for the skier to put on his skis even in a difficult situation (for example in deep snow), without first having to completely clean the underside of the sole of his shoe, and on the other hand even in the presence of a layer of snow or ice under this shoe, there is no overload, therefore no additional effort necessary to cause the opening of the binding in the event of fall for example.
