STRUTTURA DI SEDILE SMONTABILE PER TAVOLE ACQUATICHE

摘要

An auxiliary seat for a surfboard comprises a rectangular tube-form frame having two U-shaped sections telescopically connected to form the longer sides of the rectangle. A first section has a raised end for a footrest. A second section has a third U-shaped tube-form frame connected thereto to form a foldable back. Two crossmembers are fastened to the frame for attaching it to a surfboard. Expandable sleeves couple one of these crossmembers to a mast housing and the other to a casing on the surfboard.
