Patent ID: 8240697

Claim:
A gliding board comprising: a length; an upper sub-assembly comprising at least one first upper reinforcement extending longitudinally along at least two-thirds of the length of the gliding board; a lower sub-assembly comprising at least one first lower reinforcement extending longitudinally along at least two-thirds of the length of the gliding board; a primary core positioned between the lower sub-assembly and the upper sub-assembly; a frictional damping arrangement extending longitudinally along the length of the ski, the frictional damping arrangement having a length; through a majority of the length of the frictional damping arrangement, the frictional damping arrangement is completely embedded within a structure of the gliding board; the frictional damping arrangement comprising: at least one blade having a thickness of less than 2 mm and extending longitudinally between a first end and a second end; a structure enabling the at least one of the ends of the blade to slide relative to the structure of the gliding board; the frictional damping arrangement is positioned between the first lower reinforcement and the first upper reinforcement; a distance between the frictional damping arrangement and one of the first upper reinforcement and the first lower reinforcement ranges between 0 mm and four times the thickness of the at least one blade.
