Benefits of technology

"The invention is a system for controlled cooling and heating of seats, mattresses, and other articles using a convective cushion. The cushion has air flow structures and can deliver air of varying temperatures and quantities to the user. It can also have different sections with different air inlets for different users. The cushion includes a removable modular pocket with tubular spacer material that can deliver air of different temperatures and quantities. The invention also includes an improved Stirling cycle heat pump that operates more efficiently and eliminates the need for a power input. The invention can be remotely controlled and can be used in vehicles. Overall, the invention provides a more comfortable and customizable experience for users."

Problems solved by technology

One of the disadvantages of conventional gas bearings that is overcome is the fact that, when the conventional bearing is not energized sufficiently by the motion of the piston, such as when the machine is being started or stopped, the gas bearing function is significantly diminished, allowing the piston to “land” against the piston bore.
Although wear has been reduced significantly, it was not completely eliminated in these conventional systems.

Embodiment Construction

[0037]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.

[0038] 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 pl...

Abstract

A convective seating and sleeping system with a plenum for use as a mattress, cushion or as part of seat or other structure to deliver air flow to a user or users. The convective cushion includes a modular plenum made of removable pockets and a thermocouple to provide control data to selectively control the temperature and / or quantity of the air delivered to the cushion. The cushion includes the use of tubular spacer material. The cushion has deep styling lateral and longitudinal pleats and air flow structures around the pleats to provide a controlled air flow to the cushion. The invention includes an improved Stirling cycle heat pump with magnetic bearing structures and relative humidity controls and an improved thermoelectric heat pump that selectively controls the relative humidity of the air delivered to the cushion. The cushion can be activated and operated by remote operation from a telecommunications device.

Description

RELATED APPLICATION DATA [0001] This application is a continuation-in-part of pending application Ser. No. 11 / 225,605 filed on Sep. 13, 2005 which is a continuation-in-part of pending application Ser. No. 11 / 024,073 filed on Dec. 28, 2004, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This present invention relates to improved 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 ...
