The present invention relates generally to a back-supporting apparatus, back-supporting chair, and method of using the same. More particularly, the invention relates to a back-supporting apparatus that improves posture and reduces deleterious forces applied to the spine.
Many members of the population suffer from back problems. One cause of the back problems experienced by such people are the chairs used particularly during work and recreation activities, such as office chairs at work for extended periods or when relaxing at home in poorly supporting chairs, such as lounge chairs. In the past, almost all chairs have had back portions that are concave to the user, meaning that the chair back forms a curve or cup in which the central area or portion is dished or forms a concave curve when compared to the sides of the back of the chair, such that the back of the person occupying the chair resting in the concave shape of the back of the chair has a tendency to adopt a corresponding concave curved shape in which the shoulders tend to be in a rounded position extending slightly forward of the chest cavity of the person; this is not a position that is conducive to maintaining a good posture. The problem with using chairs having a generally concaved shaped back is that their use tends to make the person occupying the chair to slump or slouch forward and not sit upright. Slouching places the passive structures of the thoracic spine such as ligaments, discs, muscles, and nerves in a stretch or in a more or less continually stretched position In addition, it also places the passive structures of the lumbar spine such as the discs in a compressed position. Continual stretching of the thoracic spine and compressing the lumbar spine such as this can lead to pain and injury. In particular, the longer a person sits in a slouched position, the longer and larger are the forces placed upon the spine, which in turn results in there being a greater tendency for pain to develop in the spine. This force, over time, stretches the passive structures of the thoracic spine, and compresses the lumbar spine, which in turn, leads to the development of back pain.
Another way of describing the shortcomings of existing chairs relates to the structure and architecture of the spine and the problems which cause painful conditions in the spine. In healthy individuals, or at least in individuals with good posture, the lumbar spine, the lower back, has a curve or is curved inwardly, which is referred to as the lordotic curve or lordosis. When conventional chairs with concave backs are used, there is a tendency for the lower back of the person using such chairs to lose lordosis, which leads to abnormal deleterious forces being applied to the spine and allows the onset of conditions in the back which develop pain, damage, and injury.
Furthermore, existing support devices lack true portability, and more importantly, the ability to attach to multiple chairs or other objects, and to be easily and effortlessly changed over from chair to chair.
Therefore, there is a need for an apparatus and chair that addresses the problems caused by slumping or slouching when seated in a chair using the methods currently available.
There is also a need for a therapeutic device that reverses the effects of prolonged sitting and slouching. By lying on a device that arches the back in an extended position, this reverses a deleterious slouched position and can assist to relieve back pain.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
Unless otherwise indicated illustrations in the figures are not necessarily drawn to scale.

In exemplary embodiments of the present invention, the base 102 is formed of injection molded ultraviolet stabilized nylon, but may be formed of any suitable, flexible and resilient material. The base 102 may be a single unitary unit, or in optional embodiments, may comprise multiple units or segments 146 that are connectable via interference fit, snap fit, or any known connection conduit, discussed in greater detail with relation to
In operation, the base 102 is positioned on the user's sagittal plane, and is shaped and dimensioned to provide stability when it is coupled to an object, such as a chair. By sagittal plane it is mean that that it is positioned up and down, or longitudinally. The width the base 102 should be wide enough to avoid over-rotation should the user move, but thin enough to move with the user should the user make slight movements in his or her chair or seat. The shape of each segment, as shown, is approximately in the shape of a super-ellipse, but may be square, or in some e embodiments, the base 102 may be a single unitary body.

The male portion 502 of the snap fit fastener 500 comprises a clip 506 and cantilever snap 510, and the female portion 504 comprises aperture 508. The cantilever snap 510 is formed on a first end of the clip 506, and forms a portion of the segment itself while the aperture 508 is extruding from a second end of the clip, opposite the first end of the clip 506.
Once adjacent an additional segment 404n+1, the segments may be coupled together by inserting the male portion 502 of the snap fit fastener 500 into the female portion 504 thereby forming part of the base 102. In operation, the cantilever snap 510 is flexible in nature but like a leaf spring has force that pushes outwardly. Thus, a user depresses the button 512 on the cantaliever snap 510, inserts the male portion 502, and releases the button 512 which extends through the aperture of the adjacent segment 404n+1. The amount of deflection experienced by the present cantilever snap for a fixed load may be varied by varying the length of the cantilever snap, varying the location of the load with respect to the end of the cantilever snap, and by varying the material properties of the cantilever snap. Several variations of the above-mentioned characteristics may be performed by the present system and method. According to one exemplary embodiment, the present cantilever snap is made of plastic, having a favorable modulus of elasticity.

In optional embodiments, the back supporting members are integral and formed within the chair themselves. In other optional embodiments, the back-supporting members are clipped in and removable and replaceable as an insert. Yet in other optional embodiments, the apparatus of
In operation, owing to the spherical portions facing parts of each back supporting element, when a person sits in chair with their spine centrally located within valley regions, the presence of bulbous portions forms a generally convex curved shape. When a person rests against the forwardly facing surface of the chair back, the back of the person is forced into a generally upright position by the back supporting members contacting the erector spinae muscles on either side or adjacent to the spine, and apply pressure to the rib angles of the person maintaining an upright position so that the back of the person is pushed up and out so as to adopt a more correct anatomical position thereby maintaining lordosis of the lower back and preventing slouching of the thoracic spine, and minimizing the chances that pain could develop due to poor posture by slumping, slouching, or the like.
In optional embodiments, in operation, should the device be used on the flow on the floor as a therapeutic device, owing to the bulbous upwardly facing parts of each back supporting element, when a person lies on the floor with their spine centrally located within valley regions the presence of bulbous portions forms a generally convex curved shape of the spine. When a person lies on the upwardly facing surface of the device, the back of the person is forced into a generally extended position by the back supporting members contacting the erector spinae muscles on either side or adjacent to the spine, and apply pressure to the rib angles of the person maintaining an upright position so that the back of the person is pushed up and out so as to adopt a more extended anatomical position thereby increasing the lordosis of the lower back and thoracic spine, and reversing the effects of poor posture by slumping, slouching, or the like and increasing the chances that pain could be relieved.
