Embodiment Construction

[0039]FIG. 1 is a perspective view of one embodiment of the convective cushion 10 as applied to a mattress for cooling and heating while a user is resting or sleeping. The convective cushion 10 includes a plenum 12 having a generally air permeable top surface 14 that is secured around a perimeter 16 to a bottom surface 18. The bottom surface 18 is in one or more embodiments generally impermeable to air and as shown in FIGS. 1 and 2 can be placed on a mattress 20 to make the bottom surface 18 generally impermeable. In one or more embodiments, the mattress 20 is a foam mattress, but the present invention includes the use of a futon, coil spring mattresses, inflatable mattresses or other structures made of other materials to support the plenum 12.

[0040]As shown in FIG. 1, the plenum 12 includes multiple pockets 22 made of a synthetic material woven into a mesh of approximately 4-6 strands per inch×4-6 strands per inch with each of the pockets 22 separately removable as part of the plen...

Abstract

A multiple convective cushion seating and sleeping system for providing temperature modified air to multiple surfaces, such as a seating surface and a sleeping surface, with the same air cooling or heating source. The invention includes the use of tubular spacer material including tubular spacer fabric. A power unit including a heat pump and blower is in fluid communication with a first convective cushion by a first duct and with a second convective cushion by a second duct to provide the temperature modified air to both convective cushions for controllably heating or cooling multiple users. A thermoelectric heat pump, a Stirling cycle heat pump or other type of heat pump can be used. The invention includes the use or one or more valves to control the air flow to one or more of the convective cushions and provides for manual operation, electronic control and operation by a remote telecommunications unit. The invention can be utilized in vehicles, such as tractor trailers and recreational vehicles, and in buildings such as apartments, dorm rooms and houses.

Description

RELATED APPLICATION DATA[0001]This application is a continuation-in-part of the U.S. patent application entitled “Improved Convective Seating and Sleeping Systems” filed on Jun. 19, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This present invention relates to convective cooling and heating of seats, mattresses, mattress pads and other articles used as a cushioning device.[0004]2. Description of Related Art[0005]There are many applications and situations where it is desirable to provide for convective cooling or heating of various articles including seats, mattresses and other articles used for supporting individuals while either sitting or laying down on the article. Many of the conventional devices that have been used suffer from serious drawbacks. As one example, the resistance heated type prior art mattresses and cushions do not provide for cooling or ventilation, a major disadvantage in many parts of the world that lack adequate air conditioning.
