ABSTRACT:
The invention relates to an arrangement for changing the hardness, elasticity or rigidity of a sliding device for snow, which sliding device has a level of convexity which is predetermined during manufacture, having a stiffening device which can be fitted on the sliding device and can be changed, in terms of its action on the sliding device, by a control mechanism. The aim of the invention is, by changing the level of convexity, to be able to adapt the travelling properties of the sliding device to the respective skiing/snowboarding conditions in a particularly effective manner. This aim is achieved according to the invention in that a two-part stiffening device is arranged on the upper side of the sliding device, the sections of said stiffening device being connected to one another at the point of division by means of a spring system, and one section of the stiffening device being in engagement with a control mechanism by means of which the level of convexity of the sliding device, in relation to the non-loaded state thereof, can be set manually in two directions.
