Stuetzvorrichtung fuer den menschlichen Koerper in Sitzstellung

A support system for the seated human body comprising a two-dimensional material such as a length of netting constrained under tension to define a three-dimensional support form including in an upwardly extending length of the material a localised forwardly projecting support portion for the upper pelvic/lumbar area of the human body, the tension in the forwardly projecting support portion being preferably higher than in the remainder of the upwardly extending length of the material. In a generally horizontally extending seat portion the tension in a zone immediately forward of the ischial tuberosities supporting zone is preferably higher than the tension in the ischial tuberosities supporting zone itself.
