  • Patent number: 5876056
    Abstract: An Alpine pair ski (1) comprises a flat first sliding surface (2) and lateral surfaces (6a, b) provided with an approximately continuous concave sidecut between a first transition line A-A' defining the transition from a main section to a front section (3) and a second transition line E-E' defining the transition from the main section to a rear section (5), the course of a lower lateral edge (7a, b) between the transition lines A-A' and E-E' approximating a continuous curve. The sole on both sides of first sliding surface (2) comprises additional sliding surfaces (4) which extend upwards from the edge of the first sliding surface (2) to the lower lateral edges (7a, b) of the ski with an uplift (H.sub.s) whose value at a point on the lower lateral edge (7a, b) of the ski is given by the length of the perpendicular from this point to plane of the sole.

  • Patent number: 5511815
    Abstract: On a front section, an Alpine style ski has a greatly increased width, and the lower edges (3a') of the sides (3a) are gradually raised on this section so that they diverge upwards in relation to each of two imaginary, straight, parallel lines (2) which constitute extensions of the lower edges (3') of the sides (3) of the rest of the main body.
