Abstract

An orthopedic cushion for a support humans and animals, particularly domestic pets, includes a plurality of layers including a padding layer of slow recovery visco-elastic foam providing the orthopedic advantages of reducing pressure points and facilitating blood flow, a supporting padding layer of material which supports the slow recovery visco-elastic foam while providing additional loft and cushioning, a protective liner of a flexible waterproof yet breathable material protecting the padding from liquids of all nature, and a washable fabric cover. The pet bed of the present invention is orthopedic, washable, stain-resistant, hypoallergenic, and comfortable.

Claims

1. A cushion for domestic pets comprising:

(a) A padding layer of slow recovery visco-elastic foam;

(b) a supporting padding layer of a stabilizing material which supports the visco-elastic foam and provides additional cushioning, adjacent to said cushion of slow recovery visco-elastic foam;

(c) a protective liner of a waterproof, breathable, flexible material, enclosing both the said padding material of visco-elastic foam and said supporting padding material;

(d) a washable fabric cover totally enclosing said padding material of slow recovery visco-elastic foam, said supporting padding material, and said protective liner.

2. The cushion as recited in claim 1, wherein the supporting padding layer is comprised of a textile-based material.

3. The cushion as recited in claim 1, wherein the supporting padding layer is comprised of a foam material.

4. The cushion as recited in claim 1, wherein the supporting padding layer is comprised of a rubber material.

5. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a hydrophilic laminate.

6. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a hydrophilic coating.

7. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a microporous laminate.

8. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a microporous coating.

9. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a bi-component laminate.

10. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a bi-component coating.

11. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material comprises a material fabricated from a microfiber of a sufficiently close weave to be waterproof and breathable.

12. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner is comprised of a material fabricated with a monolithic membrane.

13. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner material is naturally oleophobic, anti-dust mite, anti-odor, anti-bacterial, anti-stain, and anti-static.

14. The cushion as recited in claim 1, wherein said outer fabric cover has a releasable closure so that said fabric cover may be removed from the said padding of slow recovery visco-elastic foam, said padding of stabilizing support material, and said protective liner, for washing.

15. The cushion as recited in claim 1, wherein said out fabric cover is comprised of a top surface, a bottom surface, and peripheral side walls disposed between said top and bottom surfaces.

16. The cushion as recited in claim 1, wherein said waterproof, breathable, and flexible protective liner is sealed closed around said padding layer of slow-recovery visco-elastic foam and said supporting padding layer in such a close-fitting and tight manner that the protective liner does not allow for the inner padding layers, of said slow recovery visco-elastic foam and said supporting stabilizing material to shift or move about within the said protective liner.

17. The cushion as recited in claim 1 wherein said cushion has numerous overall geometric shape possibilities, as in having a generally square shape, as in having a generally round shape, as in having a generally rectangular shape, as in having a generally semi-circle, as in having a generally triangular, or as in having a generally pie-shaped shape.

18. The cushion as recited in claim 1, wherein said cushion may be used by a domestic pet or human.

19. An orthopedic cushion for a pet comprising:

(a) A padding layer of slow recovery visco-elastic foam;

(b) A supporting padding layer of a stabilizing material which supports the visco-elastic foam and provides additional cushioning, adjacent to said cushion of slow recovery visco-elastic foam;

(c) a protective liner of waterproof, breathable, and flexible moisture-vapor-transmission (MVT) membrane material enclosing both said padding materials of slow recovery visco-elastic foam and said supporting padding material, and having capability to prevent liquid from reaching said slow recovery visco-elastic foam and said supporting padding layers;

(d) A washable, removable fabric cover, with a releasable closure, totally enclosing said padding material layers of slow recovery visco-elastic foam and said supporting padding material, and said protective liner.

20. The orthopedic pet cushion as recited in claim 19, wherein said protective liner of breathable, waterproof, MVT material comprises a close-weave fabric of a sufficiently close weave to be waterproof and breathable.

21. The orthopedic pet cushion as recited in claim 19, wherein said breathable, waterproof, flexible, and MVT membrane material of the protective liner is naturally oleophobic, anti-dust mite, anti-odor, anti-bacterial, anti-stain, and anti-static.
