Abstract

Device for skiing in the seated position, of the type including a seat 12 resting via a suspension system on a single ski 4, characterised in that it includes a suspension system freeing the underside of the seating part so as to make it possible to use mechanical lifts of the chair lift type, consisting of a balancing bar 7 in which the end of the front arm supports the dampers 10 attached to the other end 11 under the front of the frame 1, this balancer being articulated with the stationary part of the frame via a shaft 8, this device facilitating turns due to its great flexibility. This device according to the invention is intended particularly for skiing for handicapped persons.

Description

La présente invention concerne un apparcil qui permet la pratique du ski en position assise ; cette pratique se faisant sur un seul ski.The present invention relates to an apparatus which allows skiing in a seated position; this practice is done on a single ski.

Jusqu'alors ce type de matériel était pourvu d'un syst@me de suspension fixé, soit derriàre l'assise, soit sous celle-ci ; ce qui posait des problèmes pour emprunter les remontées mécaniques de type "télésiàge". Hitherto this type of material was provided with a fixed suspension system, either behind the seat or under it; which posed problems in using the "chairlift" type ski lifts.

L'utilisateur devait obligatoirement quitter son "fauteuil". De plus, la trop faible longueur du débattement de ces suspensions impliquait un manque de souplesse de celles-ci.The user had to leave his "chair". In addition, the too short length of travel of these suspensions implied a lack of flexibility thereof.

Ce dispositif selon l'invention permet de remédier à ces inconvénients
Il comporte en effelt un dispositif de renvoi des suspensions vers l'avant de l'appareil constitué d'un "balancier". Ce principe dégage donc le dessous de l'assise, ce qui permet le passage de la banquette du télésiàge. L'utilisateur peut donc rester assis pour l'emprunt de ce type de remontées. Ce genre de suspension apporte également, toujours par l'emploi du balancier, une plus grande souplesse de la suspension : il permet en effet d'utiliser des amortisseurs plus longs. Ceci facilitant la conduite des virages, notamment sur les bosses, en pouvant reproduire partiellement les mouvements de flexion extension des jambes (dans la pratique du ski debout), donc un allégement du poids sur le ski.Les amortisseurs étant fixés sur ce balancier (à l'avant), la "coque"(siàge) peut donc avoir plusieurs positions de réglage du centre de gravité par rapport au milieu du ski, ceci dans le cas d'un utilisateur amputé des membres inférieurs, ce qui entraine alors une répartition des charges différente. Le dit siége est pourvu en partie inférieure de moyens destinés à reposer sur la banquette du télésiàge. formés par la partie arriére du balancier constituée par les longerons d'un cadre élargi.This device according to the invention overcomes these drawbacks
In fact, it comprises a device for returning the suspensions towards the front of the device, consisting of a "pendulum". This principle therefore releases the underside of the seat, which allows the passage of the chair seat. The user can therefore remain seated when borrowing this type of lift. This kind of suspension also brings, still by the use of the pendulum, a greater flexibility of the suspension: it allows indeed to use longer shock absorbers. This facilitates the conduct of turns, especially on bumps, by being able to partially reproduce the flexion movements of leg extension (in the practice of upright skiing), thus reducing the weight on the ski. the front), the "shell" (seat) can therefore have several positions for adjusting the center of gravity with respect to the middle of the ski, this in the case of a user with a lower limb amputation, which then results in a distribution of the different charges. Said seat is provided in the lower part with means intended to rest on the seat of the chair lift. formed by the rear part of the balance formed by the side members of an enlarged frame.

FIG. 1 represents a profile of the device according to the invention,
- Figure 2 shows the use of the device on a chair lift and support by the rear part of the pendulum.

Le ldispositif représenté sur la figure n 1, comporte la partie fixe du chassis (1), solidaire en partie inférieure (1A) des fixations de sécurité (3) du ski (4) par une réplique de semelle de chaussure de ski (2) suivi d'un tronçon vertical (1 B) lui-même prolonge par une partie inclinée vers l'avant (1C) terminée par une partie sensiblement horizontale (10) d'une longueur variable dans sa partie antérieure grâce à un prolongement (5) emboitable et coulissant dans l'extrémité de celui-ci et verrouillée en position par trou et goupille, pour le réglage des reposes pieds (6)
A l'intersection de la partie (1B) et (1C) s'articule un balancier (7) par l'intermédiaire d'un axe horizontal (8) (par exemple de 25 cm pour limiter les risques de jeu latéral).A l'avant de ce balancier (9) sont fixés deux amortisseurs (100 dont l'autre extrémité est lixée en un point (11) disposé sous la partie lixe (10) du chassis. Un siàge baquet (12) est fixé sur l'extrémité (13) du balancier (7) et en un point (14) du tronçon (1C) du bati (1) par chape prévue en partie avant et sous la coque reçue, en position variable dans des trous prévus en (13) et (14). Les réglages peuvent étre disposés en position inversée : trous sur chape ou chaque sur trous avec alésage unique entre coque et balancier. En outre, en partie avant de la coque la chape est reliée à la coque par biellette (15) pour encaisser les déplacements dus aux pivotements Hu siàge (12). Le siàge (12) offre diverses positions de réglages avant, arriàre, afin de définir la meilleure position du centre de gravité.The device represented in FIG. 1, comprises the fixed part of the chassis (1), secured in the lower part (1A) of the safety bindings (3) of the ski (4) by a replica of the ski boot sole (2) followed by a vertical section (1B) itself extended by a forward inclined part (1C) terminated by a substantially horizontal part (10) of variable length in its front part thanks to an extension (5) nestable and sliding in the end thereof and locked in position by hole and pin, for adjusting the footrests (6)
At the intersection of part (1B) and (1C) is articulated a pendulum (7) via a horizontal axis (8) (for example 25 cm to limit the risks of lateral play). the front of this balance (9) are fixed two shock absorbers (100, the other end of which is fixed at a point (11) arranged under the fixed part (10) of the chassis. A bucket seat (12) is fixed on the end (13) of the balance (7) and at a point (14) of the section (1C) of the frame (1) by yoke provided in the front part and under the received shell, in a variable position in the holes provided in (13) and (14). The adjustments can be arranged in an inverted position: holes on the yoke or each on holes with a single bore between the hull and the pendulum. In addition, in the front part of the hull, the yoke is connected to the hull by link (15). absorb the displacements due to the pivoting Hu seat (12) The seat (12) offers various adjustment positions, front and rear, in order to define the best position for the center of gravity.

Lors du passage d'une bosse, l'utilisateur appuie (par son propre poids). sur le balancier (7) qui retransmet cette force sur les amortisseurs (10) la force verticale du haut en bas qui en résulte est translormée par le belancier (7) en une méme lorce verticale mais dirigée de bas en haut avec effet sur les amprtisseurs. When passing a bump, the user presses (by his own weight). on the balance (7) which retransmits this force on the shock absorbers (10) the vertical force from top to bottom which results therefrom is translated by the financier (7) into the same vertical ridge but directed from bottom to top with effect on the shock absorbers .

Le dispositif seeon l'invention est tout particuliàrement destiné à la pratique du ski pour des personnes handicapées des membres inférieurs. The device seeon the invention is particularly intended for the practice of skiing for people with disabilities of the lower limbs.
