Sliding device e.g. snow surfing board, for e.g. off-track skiing, has outer layer with cavity on sliding surface, and resistive device increasing sliding or friction resistance at level of sliding surface and pavement surface

摘要

The board (1) has an outer layer (2) with a sliding layer opposite to a pavement surface. The sliding layer has a sliding surface and edge units extending in longitudinal direction. The outer layer includes a cavity on the sliding surface, at the level of the pavement surface. A resistive device increases sliding or friction resistance at the level of sliding and pavement surfaces in the cavity zone.
