CA 2366904

In an alpine ski (1) comprising a body (2) which is composed of several elements and has on its underside a gliding surface (3) and on its upper side (7) a binding mounting area (8), and includes at least one upper chord element (4) subjected primarily to pressure loads and at least one lower chord element (5) subjected to tensile loads, the upper chord element (4) has in the middle region of the ski the shape of a flat, upwardly curved arc (6) extending in the longitudinal direction of the ski and spanning the lower chord element (5). The arc (6) of the upper chord element (4) is adapted to deflect in the direction of the lower chord element (5) in dependence upon the load exerted by the binding and is supported in the end regions of the ski in such a way that a displacement of the ends of the upper chord element (5) resulting from the deflection of the arc (6) increases the load carrying share of the end regions of the ski.

L'invention concerne un ski alpin (1) qui a un corps (2) composé de plusieurs éléments, présentant une surface de glisse (3) sur sa face inférieure et une zone (8) pour l'attache d'une fixation sur sa face supérieure (7) et contenant au moins un élément de semelle supérieur (4) sollicité principalement par la pression et au moins un élément de semelle inférieur (5) sollicité par la traction. L'élément de semelle supérieur (4) a, dans la zone centrale du ski, la forme d'un arc plat (6) bombé vers le haut qui s'étend dans le sens longitudinal du ski et enjambe l'élément de semelle inférieur (5). L'arc (6) de l'élément de semelle supérieur (4) peut être infléchi, en fonction de la charge provenant de la fixation, en direction de l'élément de semelle inférieur (5) et s'appuie sur les zones terminales du ski de telle manière qu'un déplacement des extrémités de l'élément de semelle supérieur (5) résultant de l'infléchissement de l'arc (6) augmente le pourcentage de portée des zones terminales du ski.
