摘要

The winter sports equipment in the style of a ski-bob has a sitting surface (2) connected to two spaced apart side runners (14) installed parallel to one another and interconnected by a mechanical joint arrangement in such a way that spatial movement of one runner produces a derivative spatial movement of the other runner. The joint arrangement is a parallel link assembly connected to the seat support (6), forming six pivot points.
