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
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.
