Abstract
A ski which is provided internally with vibration-damping elements. According to the invention, at least two vibration-damping elements in the form of bands or strips of constrained visco-elastic material extend longitudinally within the ski and are spaced apart therein. The bands have lengths of 10 to 20% of the total length of the ski and a spacing which can also be equal to 10 to 20% of the total length of the ski. When the ski is a tour ski, e.g. for alpine touring or cross-country, three such bands may be provided, one at the spoon or point of the ski, one in the region of the binding and one at the heel of the ski. When the ski is for downhill or slalom skiing, two such bands are provided, one at the spoon or point and the other at the binding region.
