Seat or support surface for e.g. chair, has flexible surface provided at supporting frame e.g. chair frame, as seat, so that ends of elastic wires or batons are pivoted and axially adjustable by frames

摘要

The surface has multiple base elements (1) that are in the form of strips, pipes or slats. The base elements are threaded in parallel to two wires or batons (3), where the wires or batons have bending resistance and elastic resistance. A flexible surface is provided at a supporting frame e.g. chair frame, as seat, so that the ends of the elastic wires or batons are pivoted and axially adjustable by the frames. The base elements are made of a pressure resistant material such as wood, plastic and metal, or made from steel, spring steel or resin-bound fibers such as glass or carbon fibers.
