Definitions

  • the skis are subjected to vibrations which are troublesome for the comfort of the skier and which adversely affect the performance of the ski, in particular its grip, particularly on ice and on frozen snow, when holding on course and when cornering and reduce its sliding properties.
  • FR-A-2 237 653 proposes to include in the structure of the ski a vibration damping element.
  • this damping element extends over the entire length of the ski, the comfort of the ski is clearly increased, but the grip and the holding in heading and in turns are not improved.
  • this intermediate solution has no advantage compared to that with shock absorber extending over the entire length of the ski.
  • a ski which is of the type of those comprising a damping system constituted by a visco-elastic material constrained included in their structure, and whose originality lies in the fact that it comprises at least two strips of such material, having respective lengths of 10 to 20% relative to the total length of the ski and arranged, with an interval between them, one at the end of the tip and the other in the area skate.
  • the number and the relative position of the bands serving as shock absorbers are a function of the destination of the ski and of the qualities which it must present for this destination.
  • a ski according to the invention comprises three shock absorbing elements placed respectively in the tip area, in the heel area and in the skate area.
  • Such a ski makes it possible to achieve the desired goal, which is to combine comfort with the efficiency of the ski, that is to say its attachment on ice or on icy snow and its good behavior in heading and in cornering, as well as an effective damping of the vibrations to which it would be subjected if it were not provided with these damping elements, in particular in the case where the ski moves on a hard and irregular surface.
  • each damper is constituted by a band of constrained visco-elastic material; but the two bands are then placed, one in the spatula area and the other in the skate area.
  • the ski represented in FIG. 3 is a ski intended particularly for giant slalom. It differs from the previous one in that it only has two damping elements (15) and (16).
  • the one (15) is placed in the spatula area (17); the one (16) is placed in the pad area (18); and for each their length is of the order of 25 centimeters if the ski has a length of between 2 meters and 2 meters 05.
