Abstract (en)
[origin: WO8805676A1] The ski comprises at its top part a longitudinal rib usable particularly for the lateral guiding of a shoe. In order to improve the technical qualities of the ski without substantially increasing its weight, the cross-section of the rib is comprised at least in the front part of the central area (A) where the shoe sole is bearing, of the superposition of at least two elementary sections (2, 3) having each the shape of a quadrilateral and interconnected by a common side forming the lower side of the upper elementary section and the upper side of the lower elementary section of which the lower side is horizontal, the lateral sides (7, 8) of the lower elementary section (3) converging upwards and being more inclined with respect to a vertical and longitudinal plane than those (5, 6) of the upper elementary section (2).
