Patent ID: 7344148

Claim:
A mechanical device for modifying radial geometry of a ski, comprising: at least one rod; a plurality of transmission elements interposed between the ski and said at least one rod, said at least one rod having a longitudinal axis extended substantially along a longitudinal direction of the ski, the plurality of transmission elements being configured to transform a first displacement of the at least one rod into a second displacement, the first displacement being caused by a flexion of the ski, oriented along the longitudinal axis and directed towards a first end of the ski, the second displacement being oriented along a direction intersecting the longitudinal axis and directed towards an outside of the ski, wherein the plurality of transmission elements apply the second displacement at a selected place of the ski to produce a thrust generating a transverse deformation of the ski along a cross-section of the ski during the first displacement of the at least one rod, and the plurality of transmission elements are configured to apply a third displacement to produce a reverse thrust that is opposite in direction to the thrust produced by the second displacement when the flexion of the ski is removed.
