Definitions

  • the ski in the central part zone located in the vicinity of the rear contact line, is also more rigid than a traditional ski.
  • a ski length L1 of 570 millimeters, starting from the front contact line 5, is retained at its two ends by free supports 9 and 10, while its center is subjected to a force 11 substantially perpendicular and of an intensity of 200 newtons; the central zone of this ski part located between the two free supports 9 and 10 moves elastically over a distance D1.
  • the front contact line 5 is generally measured by introducing a cubic wedge 20 of 1 cm3 under the spatula and corresponds to the point 9.5 cm distant from the center of the wedge towards the middle of the ski. This theoretical determination is necessary to obtain good reproducibility of the measurements.
  • the rear zone of a cross-country ski according to the present invention has a relatively high rigidity compared to that presented by a traditional cross-country ski.
  • This rigidity can be obtained by any means such as the presence of an internal rigid reinforcement plate of the ski, these means being within the reach of those skilled in the art.
  • the stiffness can be measured by a test shown in FIG. 16, similar to the test in FIG. 15, in which the posterior ski area situated on a length L2 of 570 millimeters from the rear contact line 6 of the ski, is resting on two free supports 12 and 13, its center being subjected to a substantially perpendicular force 14 and of an intensity of 200 newtons, the rear contact line 6 is, in general, measured at 5 centimeters from the rear end of the ski. This rigidity is significantly greater than that of traditional cross-country skis.
