The supporting body () consists of a relatively stiff first plastic and has a number o recesses (), which pass through the supporting body () and are arranged in such a manner that the supporting body () is flexible in a longitudinal section provided with the recesses () and resists pressure forces. The skin () consists of a relatively supple second plastic and is placed on the supporting body () in such a manner as to close the recesses () in a tight manner and transfers pressure forces acting thereupon to the supporting body ().
