Device for damping vibrations of a ski

A ski equipped with a device intended to damp vibrations, said ski comprising an elongated beam having a stiffness, with a central portion for mounting bindings, said device comprising at least one flexion strip which flexes with said ski relative to bindings when mounted on said ski, said strip extending longitudinally and having two ends, one of said ends being connected to said ski by rigid attachment means, said flexion strip comprising at least one free end which is displaced longitudinally relative to the ski when the ski is biased in flexion, and being spaced longitudinally from said rigid attachment means, wherein said free end of said flexion strip is connected to the ski by separate shearing means which is sheared during longitudinal displacements, damping said longitudinal displacements of said free end, said shearing means being interposed vertically between said free end of said flexion strip and an upper surface of said ski.
