A body-supporting device forming the seat (1) and/or the backrest (15) of a chair and adapted to avoid sweating caused by the thermal insulation of the chair is characterized by the fact that at least those sections (2) of the exterior surface of the device that form the support surfaces for parts of the body of a person sitting in the chair are made of air-permeable material. At least one opening (11) to the exterior is arranged in said device to communicate with the interior side of said air-permeable sections (2). A suction device capable of producing a negative air pressure, such as a suction turbine, may be connected to said opening. The interior of the body-supporting device is so arranged that, when a suction device is thus connected and is running, air that is exterior to said support surfaces will be drawn through the air-permeable sections (2) and via the interior of the body-supporting device and out of it through said opening (11), in order to remove heat radiated by the body of the person, in particular from the region between said parts of the body and the air-permeable sections, and to cool the latter by means of the airstreams thus created. |
