Abstract

Air conditioned mattresses have a core and at least one encasement configured to receive a conditioned flow of air into the encasement and to allow conditioned air to flow out of the encasement to a sleep surface of the mattress. Additional conditioned air conducting layers are provided in combination with the encasement.

First claim

What is claimed is:

1. An air conditioned mattress having:
a core layer; and
an air distribution layer positioned over and joined to the core layer, the air distribution layer including a foam layer and at least one spacer layer, the foam layer and the at least one spacer layer completely enclosed by at least one encasement configured to receive a conditioned flow of air into the encasement and to allow conditioned air to flow out of the encasement;
at least one conduit extending through said core layer, into said encasement, for air distribution through said spacer layer and said distribution layer and further air distribution through perforations in said encasement;
wherein said distribution layer comprises a plurality of foam segments, with adjacent foam segments at least partially spaced from one another by a channel and wherein a gel material is disposed in each channel;
wherein the encasement is comprised of a sheet of pliable material having a top side positioned adjacent to the foam layer and a bottom side positioned adjacent to the at least one spacer layer; and,
wherein the at least one spacer layer includes a plurality of interconnected fibers configured to allow air to pass therethrough.

2. The air conditioned mattress of claim 1 wherein the at least one spacer layer is comprised of spacer material.

3. The air conditioned mattress of claim 1 wherein the encasement is perforated.

4. The air conditioned mattress of claim 1 wherein the encasement is comprised of an air permeable material on the top side and a non-air permeable material on the bottom side.

5. The air conditioned mattress of claim 1 wherein the foam layer includes perforations.

6. The air conditioned mattress of claim 1 , said encasement having selectively located perforations to control at least one of pressures or flow rates of said conditioned air passing therefrom.

7. An air conditioned mattress having:
a core layer; and
an air distribution layer positioned over and joined to the core layer, the air distribution layer including a foam layer and at least one spacer layer, the foam layer and the at least one spacer layer completely enclosed by at least one encasement configured to receive a conditioned flow of air into the encasement and to allow conditioned air to flow out of the encasement,
at least one conduit near one end of and extending upwardly through said core layer, into said encasement, to distribute air through said spacer layer and to said foam layer and further for air distribution through perforations in said encasement;
wherein said distribution layer comprises a plurality of foam segments spaced from one another by at least one channel and wherein a gel material is disposed in each of said at least one channel;
wherein the encasement is comprised of pliable material, and
wherein the at least one spacer layer includes continuous fiber strands with major segments arranged in a generally vertical orientation traveling between opposing planar sides of the spacer layer.

8. An air conditioned mattress having:
a core layer;
an air distribution layer positioned over and joined to the core layer, the air distribution layer including a foam distribution layer and a spacer layer, the spacer layer including a plurality of interconnected fibers to allow air to pass therethrough; and
at least one encasement configured to receive and pass conditioned flow, the encasement comprised of a sheet of fabric that completely encloses the foam distribution layer and the spacer layer;
first and second conduits extending upwardly through and near an end of said core layer, into said encasement, to distribute air through said spacer layer and to said distribution layer for distribution through perforations in said encasement;
wherein the foam distribution layer is comprised of a plurality of foam segments, with adjacent foam segments at least partially spaced from one another by a channel; and
wherein a gel material is disposed in each channel.
