Abstract
A seating construction with joined seat and backrest parts has a plenum into which is received temperature conditioned air. Coil springs define the plenum and a covering is secured over the springs consisting of, from the inside out, a metal mesh layer, an elastomer sheet with a number of openings, and an air permeable fabric layer. The elastomer sheet 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.
Claims21
A seating construction having joined seat and backrest parts enclosing a common plenum for receiving temperature conditioned air therein, comprising:
- spring means within the common plenum;
- and
- a covering secured over the coil springs including, from the springs outward,
- a metal mesh layer,
- an elastomer sheet having a plurality of openings extending therethrough, an air permeable fabric layer.
A seating construction comprising:
- a seat includes,
- a base formed from a plurality of foam members, at least two of which have foam of different densities,
- spring means resting on the base, metal mesh secured over the spring means,
- an elastomer sheet on the metal mesh having a plurality of openings extending therethrough,
- an outer air permeable material over the elastomer sheet,
- a conditioned air entrance conduit for directing conditioned air through the spring means,
- a backrest includes,
- a foam base,
- spring means,
- metal mesh covering the spring means,
- an elastomer sheet over the metal mesh,
- a conditioned air entrance conduit for directing air through the spring means;
- a headrest having a hollow interior and a flexible connection hose interconnecting the headrest interior with the backrest spring means;
- a thermoelectric air conditioning unit having an ambient air input and a conditioned air output;
- and
- a proportioning valve interconnecting the air conditioning unit output and the entrance conduits for the seat and backrest.
