A layer of a second material is placed over the seams and sewn thereto create a plurality of vertical slots. After staves are inserted in the slots, a layer of a resilient material is placed over the second material and a layer of perforated material is placed over the resilient material. A strip of material is placed on the peripheral surface of the inner and outer members and sewn to define the belt. First and second fasteners on the first and second side sections joined together to apply a force through the staves to provide support for an underlying area of the torso of an individual to assist in attaining a desired posture.

Description

This invention relates to a belt for providing support to the torso of an individual having staves located in a plurality of vertical pockets that define a ring for gently applying pressure on an area underlying the belt to assist in attaining a desired pain free posture.

BACKGROUND OF THE INVENTION

Back pain is a common problem experienced by many people. Most low back pain is a result of soft tissue injure such as disc herniation of spinal disc that does not require surgery but may require the use of anti-inflammatory drugs and medication therapy. During rehabilitation it may be necessary for a person to employ some type of bracing, such as disclosed in U.S. Pat. Nos. 5,267,947; 5,407,422; 5,569,171; 5,737,774; and 6,676,617, to support the effect area and perform normal daily activities. The brace functions to alert the person of posture, flexion and movements that may expand the injury or extend the healing time for the person. However, if a brace is too rigid or continually worn by a person, the time for recovery of an injury to the soft tissue may be extended, as the person may become too dependent on the brace.

SUMMARY OF THE INVENTION

This invention provides a belt that provides support for soft tissue of the spine of a person such that a substantially constant force may be applied to vertebrae while a reduced force is applied as a pressure ring to the tissue surrounding the vertebrae to assist in achieving a desired posture.

In more particular detail, the belt is defined by inner and outer members with intermediate layers of a material there between to define a semi-rigid structure having a shape in center section that approximates the thoracio-lumbar vertebrae and sacro-coccygael of an individual. The outer member is created by sewing a plurality of strips of a first material together to create a desired length for the belt. The individual strips have a desired length such that on sewing the strips together, a plurality of vertical seams are created along an entire length of the belt and a center section is created that transitions into first and second side sections. The length of the center section and first and second side sections are about equal in defining the length of the belt. A first layer of an intermediate second material is placed over the outer member and attached thereto by sewing first and second parallel seams adjacent the plurality of vertical seams in the outer layer to create a corresponding plurality of vertical slots in the center and side sections. A stave is inserted in each slot and an intermediate layer of a third material is placed over the intermediate layer of the second material. The third material is an open pore sponge that has a resiliency such that it may be compressed on the application of a force. An inner member defined by a fourth material that has perforations therein to allow the communication of air there through is placed over the intermediate layer of third material. A binding defined by a strip of a fifth material is placed around the peripheral surface of the first, second, third and fourth materials and sewn to define a unitary structure wherein the plurality of staves are located in a vertical position along substantially the entire length of the resulting belt. A first fastener is attached to the first side section of the outer member and a second fastener member is attached to the second side section of the outer member. On positioning the belt on a torso of the individual, the first fastener and second fastener are joined together with a force to exert a corresponding constant force on the thoracio-lumbar vertebrae and sacro-coccygael and a variable force through the plurality of staves on the underlying area of the torso covered by the inner member such that a desired pain free posture may be attained.

An advantage of the present invention is achieved through a belt whereby a direct force may be applied to a specific area of the torso and a variable force applied to the area surrounding the specific area that allows flexible movement while providing support to soft tissue of the muscles associated with the movement.

A further advantage of this invention resides in a belt that is semi-rigid to provide support for soft tissue while allowing flexible movement for an individual to perform daily activities.

DETAILED DESCRIPTION

In this application a same number may be used with respect to a different component if a same feature is present.

An individual suffering from a strain or back injury may assume a posture, as illustrated in FIG. 1, as a result of pain associated therewith. In such a situation, one or more disc 11,11′ . . . 11ⁿ that separate the vertebrae of the thoracio-lumbar spine 10,10′ . . . 10ⁿ, may extrude inwardly and bulging outwardly such that the curvature of the thoracio-lumbar spine 10,10′ . . . 10ⁿ may be changed and as a result act on nerves, as schematically illustrated in FIG. 2. Depending on the pain experiences by the individual, treatment for such injury may include rest, surgery, or strengthening exercises. In any event, in order for an individual to perform normal activities it may be advisable and/or necessary to wear a belt 20 around the lower region of torso 18, as illustrated in FIG. 3, to support the muscles and soft tissue in the area of the thoracio-lumbar vertebrae 10,10′ . . . 10ⁿ. The belt 20 of the present invention is designed to provide a constant force or support for at least the second through the fourth lumbar vertebrae 10,10′ . . . 10ⁿ, variable support up to the eighth/ninth thoracic vertebrae 10,10′ . . . 10ⁿ and cover the sacro-coccygael junction 12 to assist in achieving a desired posture that approximates a normal curvature of the spine as illustrated in FIG. 4. When the belt 20 firmly surrounds the torso 18 of an individual, hip and leg movement is not restricted provided and the stomach muscles 22 are also supported in a manner such the flow of blood to the muscles and soft tissue is not restricted and as a result the time to heal the injured tissue may be reduced. The belt 20 provides a constant force to the center section of the belt and a variable force that is gentle to provides a massage effect to the soft tissue underlying the belt to ease any discomfort and pain the individual may experience.

In more particular detail, the belt 20 is defined by a plurality of layers of material that form a semi-rigid structure and may be manufactured through the following process.

A first plurality of strips 24,24′ . . . 24ⁿ of a first material are sewed together see FIG. 5, to create a first side section 26 for an outer member 100 having a first length 28 and a first width 30 to define a shape with a plurality of vertical seams 32,32′ . . . 32ⁿ, as illustrated in FIG. 6. The preferred first material is leather having a thickness of about 3 ply.

First 34, second 36 and third 38 pieces of a intermediate second material are layered over the first side section 26, see FIG. 7, and sewed along the plurality of vertical seams 32, 32′ . . . 32ⁿ to create vertical seams 40 and 42 adjacent each vertical seam and thereby produce a plurality of vertical slots 44, 44′ . . . 44ⁿ in the first side section 26, as illustrated in FIG. 8. The space between the edges of the first 34, second 36 and third 38 pieces of the second material define linear hinges 46 and 48 such that the area covered by the upper first piece 34 and the area covered by the lower third piece 38 may independently flex with respect to the second piece 36. The preferred second material is suede leather.

A second plurality of strips 24,24′ . . . 24ⁿ of the first material are sewn together to create a second side section 50 having a same first length 28′ and a same first width 30′ to define a shape for a second side section 50 with a plurality of vertical seams 32,32′ . . . 32ⁿ, as the first side section 26 illustrated in FIG. 5.

As with the first side section 26, first 34, second 36 and third 38 pieces of the intermediate second material for the second side section 50 are layered over the second side section 50 and sewed along the plurality of vertical seams 32, 32′ . . . 32ⁿ to create first and second vertical seams 40 and 42 to produce a plurality of vertical slots 44, 44′ . . . 44ⁿ in the second side section 50. The space between the edges of the first 34, second 36 and third 38 pieces of the second material for the second side section 50 also define linear hinges 46 and 48 such that the area covered by the first piece 34 and the area covered by the third piece 38 may independently flex with respect to the second piece 36. The first 26 and second 50 side sections are complementary and designed such that the length of a section may be changed by adding additional strips 24 of the first material at a transition point 29, 29′.

A third plurality of strips 24,24′ . . . 24ⁿ of a first material are sewn together to create a center section 52 having second length 54 and a second width 56 with a plurality of vertical seams 32,32′ . . . 32ⁿ, to define a shape as illustrated in FIG. 5.

First 34′, second 36′ and third 38′ pieces of the intermediate second material are layered over the center side section 52 and sewed adjacent the plurality of vertical seams 32,32′ . . . 32ⁿ to create first and second vertical seams 41 and 43 and ultimately the plurality of vertical slots 44,44′ . . . 44ⁿ in the center section 52 that are parallel to the vertical slots in the first 26 and second 50 side sections.

A strip 24 of the first material for at least the center section 52 is defined by a desired length having a first end 23 and a second end 25 with a first width “W” at a mid-point “m” between the first end 23 and the second end 25 that expands to a second width “W+1” at a points 27, 27′ respectively located adjacent the first 23 and second 25 ends. When the plurality of strips 24 are sewed together to define a length 54 for the center section 52, a desired vertical arc is created between the first end 23 and the second end 25 that is designed to approximate the shape of the thoracio-lumbar vertebrae 10,10′ . . . 10ⁿ of the spine of an individual as illustrated in FIG. 4.

The first side section 26 is sewn to the center section 52 at a transition point 29 and the second side section 50 is sewn to the center section 52 at a transition point 29′ to define a desired length for a resulting belt 20, as shown in FIG. 5. With the first side section 26 and second side section 50 sewn to the center section 52 a central section having a uniform width defined by the second piece 36 of the second intermediate material substantially extends along the entire length of the belt 20, while an upper section 62 has a first variable width that substantially extends along the entire length of the belt 20 and a lower section 64 has a second variable width that substantially extends along the entire length of the belt 20.

The plurality of vertical slots 44,44′ . . . 44ⁿ substantially extend from the first end 19 to the second end 21 and each receive a corresponding stave 66 as illustrated in FIGS. 9 and 10. The staves on being inserted in the slots 44, 44′ . . . 44ⁿ are designed to extend to approximately the points 27, 27′ adjacent the first 23 and second 25 ends of the strips 24 of the first material.

Once a stave 66 is placed in each slot 44,44′ . . . 44ⁿ, a single piece 68 of an intermediate third material that has a uniform thickness, see FIG. 11, is placed over the entire length and width of the outer member 100 with the layer of the first 34′, second 36′ and third 38′ pieces of the intermediate second material attached thereto. The intermediate third material is preferred to be a sponge material that has a resiliency that is compressible on the application of a force thereto.

Next, a layer 70 having a first member 72 and a second member 74 of a fourth material is placed over the layer of the single piece 68 of the third material to define an inner member 102 for the belt 20, see FIGS. 12 and 13. The first member 72 and second member 74 are complimentary and have a seam 75 that is located at the mid-section of the center section 52 of the outer member 100. The fourth material is preferred to be leather that has perforations 73,73′ . . . 73ⁿ therein, only a few of which are shown, allow the communication of air there through.

Thereafter, a centering tab 76 is placed located at the top of the seam 75, see FIG. 14 and a binding strip 90 of a fifth material placed to cover the peripheral surfaces of the first, second, third and fourth materials, see FIGS. 15, and 16. The binding strip 90 is sewn to secure the inner member 102 to the outer member 100 such the stave 66 in the slots 44,44′ . . . 44ⁿ are retained in a vertical position with respect to the length of the belt 20.

A first fastener arrangement 81 consisting of loop members 80a,80b and 80c are attached to the first side section 26 and a second fastener arrangement 83 consisting of straps 82a, 82b and 82c are attached to the second side section 50, see FIGS. 17 and 18. Loop member 80b and strap 82b are aligned located along the center line of the length of the belt 20 while loop member 80a and strap 82a and loop member 80c and strap 82c are located in an alignment above the hinges 46 and 48.

When the first 81 and second 83 fastener arrangements are attached to the first 26 and second 50 side sections, the manufacture of belt 20 is completed.

The plurality of strips 24,24′ . . . 24ⁿ that make up the outer member 100 may be sewn together and the first 34, second 36 and third 38 pieces sequentially attached thereto to define the plurality of vertical slots 44,44′ . . . 44ⁿ when a quantity of belts have a same or fixed length rather that making the first 26 and second 50 side sections and then attaching them to the center section 52.

Method of Use

Belt 20 is placed on the lower torso 18 of an individual and with the centering tab 76 located along the vertical axis of the spine such that the upper section 62 reaches to approximately the ninth thoracic vertebrae, the center section 52 covers the second through the fourth lumbar vertebrae and the lower section 64 covers sacro-coccygael 12. With belt 20 firmly secured to the individual, a force applied through the center section 52 is constantly applied to the second through the fourth lumbar vertebrae while a variable force is applied to the soft tissue adjacent the center section 52 through the staves 66 act to assist in achieving a desired posture that approximates a normal curvature of the spine as illustrated in FIG. 4. The side sections 26 and 50 are designed to hold to intestines at the front of the waist of the individual upward toward the chest. Because of water retention by the intestines, the organs in the abdomen have a tendency to drop resulting in stretching of blood vessels associated with the organs and as a result the effectively efficiency of the organs may be reduced. By supporting the abdomen, the blood vessels return to a normal size and allow unrestricted circulation of blood through to organs and contribute to the return of normal functioning including the healing of injured tissue associated with the thoracio-lumbar vertebrae.
