Abstract:
A snowboard, of the type constituting a board for surfing on snow with the surfer's body placed crosswise with respect to the longitudinal axis of the board, this snowboard having:a front portion comprising a front turned-up tip starting at a front line of contact,a central portion defining a binding mounting area and having a width between 150 and 300 millimeters,a rear portion comprising a turned up heel starting at a rear line of contact,a distance between said front and rear line of contact defining a supporting length Lp,a sole for gliding,a first slit through the thickness of at least the front portion,a second slit through the thickness of at least the rear portion,wherein a stiffness of the front portion and of the rear portion, is measured by the deflection f obtained by pressing on the snowboard, with a force of 40 Kgf, applied at a middle distance between two supports supporting the board flat and a first of said two supports placed on the line of contact, front or rear respectively depending on whether it is question of the stiffness in the front portion or of the stiffness in the rear portion, and a second of said two supports placed at a distance from the first, towards the rear or towards the front respectively, which is equal to:(Lp/2).times.0.55,wherein the stiffness is above a stiffness corresponding to a deflection value f of 16 millimeters.
