Climbing Aid, Ski and Method for Producing a Climbing Aid

Abstract

A climbing aid for a ski has a plane base element which is connected on the inner side to a fastener to be detachably fastened to a running surface of the ski and which is connected on the outer side to backwards-slipping prevention elements acting contrary to a direction of travel. A flexible plastic support material forms the base element, and the backwards-slipping prevention elements are integrally formed with the plastic support material. In lateral regions, the base element has backwards-slipping prevention elements with push-off wings positioned obliquely to the direction of travel and, in the central region, has backwards-slipping prevention elements with push-off wings arranged substantially perpendicular to the direction of travel. The push-off wings of the backwards-slipping prevention elements of a first type are of lesser length and/or of lesser height than the push-off wings of the backwards-slipping prevention elements of a second type.
