Abstract
Alpine ski (1) which can be broken down over its length into a tip area (2), a binding area (3) and a heel area (4), in which the side line is such that the binding area (3) has a minimum width level (LP), the tip area (2) has a front maximum width level (LS), and the heel area (4) has a rear maximum width level (LT), characterized in that:the radius of the side line, calculated on the basis of three points (5, 6, 7) on the side line, respectively a first point (5) located at the front maximum width level (LS), a second point (7) located at the rear maximum width level (LT), and a third point (6) located centrally between the levels (LS, LT), is between 7 and 21 meters;the pressure distribution along the side line is such that, when the ski is placed on a flat surface (20) so that its underside (22) forms an angle (&agr;) of 45° with the flat surface (20), and when the ski receives, at the location of the center of the boot, a force (F5) of 400 Newtons perpendicularly to its underside (22), the pressures measured along the side line differ by less than 10% from the average value of the three pressures measured respectively at the rear maximum width level (LT), at the minimum wi…
