Spinal tension and pressure relieving body support apparatus

a body support and spine technology, applied in the field of mattress and cushion, can solve the problems of low i.f.d. rating of foam, low rate of recovery, low rebound and/or memory characteristics, etc., and achieve the effect of reducing both spinal tension and pressure, facilitating the ability of the nervous system, and improving blood circulation

Benefits of technology

[0016]By having multiple layers of foam having different thickness, memories, and/or densities, the support layers of the present invention combined can facilitate the ability of the nervous system to become bett...

Problems solved by technology

Foams with low I.F.D. ratings, popularly known as low “memory” foams, not to be confused with latex foam or higher I.F.D. rated non-conforming polyurethane foams, have low rebound and/or memory characteristics as well as a low rate of recovery.
This low memory rating means that all mattress or seat cushion applications bearing the low memory or con...

Embodiment Construction

[0038]A body support apparatus 100 according to an embodiment of the present invention is illustrated at FIG. 1. Body support apparatus 100 generally has multiple foam layers 120. Foam layers 120 may include core layer 122, intermediate layers 124, and outer layers 126. Body support apparatus 100 presents top surface 128. Top surface 128 of body support apparatus 100 generally evenly redistributes the weight of a user through foam layers 120 to minimize pressure points between the user and body support apparatus 100.

[0039]In direct contrast to the low-memory, conforming, or viscoelastic foams previously described, suitable foams according to the present disclosure exhibit generally higher memory, higher rate of recovery, and higher resistance to compression than the low-memory, conforming foams. Suitable foams according to the present disclosure can include: (1) a high-density latex, such as a natural latex, that is non-conforming, non-heat sensitive, and non-viscoelastic and has a ...

Abstract

A therapeutic support apparatus comprises multiple layers of foam having different densities and memories. The support apparatus comfortably supports the weight of a user while minimizing pressure points between the user and the support apparatus. Each foam layer has a unique density and memory based upon the type of tissue the layer is intended to support. A relatively low-memory outer foam layer made from latex non-viscoelastic foam substantially supports skin and subcutaneous tissue. A relatively high-density and medium-memory intermediate layer made from polyurethane foam supports muscle tissue. A relatively high-density and high-high memory core layer made from polyurethane foam supports the spine. In combination, these layers minimize hyperextension and promote blood circulation and comfort while the support apparatus is used by a user positioned in a supine, recumbent, or sideways-lying position.

Description

CLAIM TO PRIORITY[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 830,363 entitled SPINAL TENSION AND PRESSURE RELIEVING BODY SUPPORT APPARATUS and filed Jul. 12, 2006, and U.S. Provisional Application No. 60 / 899,496, entitled PRESSURE RELIEVING BODY SUPPORT APPARATUS and filed Feb. 5, 2007, which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to mattresses and cushions. More specifically, the present invention relates to an apparatus for supporting a human body in a supine, recumbent, seated or sideways-lying position in a manner that relieves tension and pressure on the spine and promotes blood circulation.BACKGROUND OF THE INVENTION[0003]Nearly 80 million or fifty percent of working Americans are disabled by back pain at some time in their lives. It is estimated that one-third of men and one-half of women will prematurely retire from their careers because of back pain. Appr...
