Abstract: A snowboard with a core and a flexible running surface layer which has between the core and the running surface layer at least one hollow chamber, which can be filled with a gaseous or liquid medium.

Abstract: A running-surface plastic coating for skis which comprises a running surface forming a climbing aid and having a multiplicity of teeth which are aligned in the longitudinal direction of the ski and terminate towards the rear end of the ski in a pointed end capable of being bent upwards, said teeth being defined by two families of parallel running-surface cuts intersecting each other in the running surface, the individual families of cuts being inclined to a normal of the running surface in opposite directions wherein the running surface cuts at least substantially have the shape of circular segments and include an angle of at least 60.degree. with a running-surface normal, and that the relative spacing of the running-surface cuts is at most 1 mm.

Abstract: A running-surface plastics coating for skis comprises a running surface forming a climbing aid and provided with a multiplicity of tongues (4) which are aligned in the longitudinal direction of the ski and terminate towards the rear end of the ski in pointed ends capable of being bent upwards to provide a means for reducing the sliding resistance in the running direction without impairing the climbing aid. The tongues (4) are defined by cuts (2a, 2b) provided in the running-surface coating (1), at an acute angle with each other, the cuts extending from the plane running surface toward the underside of the ski and including an acute angle with that plane so that the inwardly and upwardly slanted side edge surfaces of each tongue are rhomboidal and diverge with respect to each other from the tip of that tongue.
