<p>A seating construction 20, with joined seat 22 and backrest 24 parts has a plenum into which is received temperature conditioned air. Coil springs 36 define the plenum and a covering is secured over the springs consisting of, from the inside out, a metal mesh layer 42, an elastomer sheet 44 with a number of openings 46, and an air permeable fabric layer 50. The elastomer sheet 44 behaves as a viscous liquid when subjected to forces and shocks. An alternative to the elastomer sheet is a baglike layer filled with fluid with a number of openings provided to enable passage of conditioned air through the layer.</p> |
