ABSTRACT:
A ski comprises a longitudinally extending body defining a longitudinal median plane and having a sole substantially perpendicular to the plane and adapted to slidably engage a surface. The sole has a central zone lying between front and rear contact zones. The body comprises a core having opposed top and bottom walls, and opposed lateral walls, the core extending substantially the length of the body. The body further includes a shell having a top layer overlying the top wall of the core and lateral surfaces spaced from respective lateral walls of the core. The shell further includes lateral strips of viscoelastic material interposed between each lateral surface of said shell and the respective lateral walls of the core for forming a shock absorber. The cross-sectional area of the lateral strips are a non-constant function of length along the body of the ski at least between said contact zones. As a consequence, a desired distribution of shock absorption properties along the length of the ski can be established by suitable selection of the cross-sectional area of the strips.
