Ski having improved shock absorption and vibration resistance

Abstract

A ski for use on snow comprises a longitudinally extending body defining a longitudinal median plane and having a sole substantially perpendicular thereto for slidably engaging a surface. The sole has a central zone lying between front and rear contact lines. The width of the body is established by opposed lateral surfaces, and the thickness of the body is established by an upper wall opposed to the sole. A longitudinal core extends along the length of the body between front and rear ends of the ski and has a width established by lateral side walls that respectively face the lateral surfaces of the body. The thickness of the core is established by upper and lower walls. The ski also includes mechanical resistance elements, internal longitudinal shock absorption members made of a viscoelastic material, and filling elements connecting the resistance elements to the other elements. The internal shock absorption members are in the form of a pair of lateral strips of viscoelastic material, each strip being sandwiched between a lateral surface of the body and the facing lateral wall of the core. The lateral side walls of the core make respective inclination angles A and B with the sole of the body, the inclination angles being a nonconstant function of the length of the core for effecting mechanical shock absorption properties which vary longitudinally along the body.
