[origin: US6109688A] PCT No. PCT/EP97/02419 Sec. 371 Date Dec. 7, 1998 Sec. 102(e) Date Dec. 7, 1998 PCT Filed May 12, 1997 PCT Pub. No. WO97/47220 PCT Pub. Date Dec. 18, 1997Upholstery for a seat, rest or couch. The upholstery includes internal channels through which draining air may flow. Valve means that open under load or compression control air flow through the channels. The flow of draining air is increased automatically or given a desired flow distribution by the surface area pressure controlled by a seated person. The cross sections of the valve means and the channels may be designed so that even a very small pressure difference and correspondingly little energy expenditure will provide a satisfactory air flow rate.
