Abstract (en)
[origin: EP0780143A1] The ski or snow-board (1) has a lower sliding surface and an upper surface with boot fastening clamps (3,4) and a regulator for varying the rigidity of the ski/snow-board. The regulator comprises an upper elongated platform (2) carrying the clamps, fixed or hinged to the board by its forward end, having an intermediate support (12) which is either fixed or sliding, an elastic block, and a pair of cams (14) at the rear end. The cams are located on the underside of the platform and the upper surface of the board and have interacting sloping surfaces (15,17) which form an angle of 30 - 60 degrees, and preferably 45 degrees, with the board's upper surface. In a variant of the design one of the cams can be a cylindrical roller, turning about an axis perpendicular to the board's median lengthwise plane, and the cams can be surfaced with a friction reducing material, such as PTFE.
