CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Provisional Application Ser. No. 60/954,906 filed Aug. 9, 2007, and also from International Application PCT/US2008/072838 filed Aug. 11, 2008, the entire contents of each of which are herein incorporated by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to a back support system that is fully rigid under the weight of a user. More specifically, the present invention relates to a comfortable and inexpensive back support system and method for the same, wherein the fully rigid back-support system provides projected and distended center liner support and curved portions from the surface on where a human being reclines or lies and requires back support. 
         [0004]    2. Description of the Related Art 
         [0005]    Over time, human beings have inevitable problematic waist, back and neck discomfort (collectively back discomfort) resulting in fatigue and/or pain to the detriment of the human individual&#39;s quality of life and work performance. The related art involves proposed solutions to these inevitable human back frailties, including surgery, cushioned supports, and even non-support via so-called knee-type chairs, as will be discussed below. 
         [0006]    To compensate for the pressures of standing and vertical orientation, the human spine has adapted a differing spinal column from other large mammals supported on four legs. In addition, the human neck is downwardly urged along a bending moment to the front because human head became heavier and heavier following the evolution of human brain and, with the spinal support at the rear of the skull, necessarily there is a cantilevered force along the skull-moment-arm under gravity to round the neck downwardly. Accordingly, humans are forced to pull their heads upwardly via musculature to see directly forward. Additionally, the human back, including musculature, is roughly flat instead of ridge shaped or bowed like that of other mammals. Finally, the bones of the spine are focused or orientated towards the front of the body from the back surface due to residual evolutionary effects of walking on all four limbs—e.g., the spinal bones include guiding spurs for protecting nerve endings and exhibit similar structural shapes as those of many four-footed animals. Thus, the human spinal construction has not yet fully adapted to an upright posture and over time this results in back pain for many. 
         [0007]    It is generally recognized that modern-day humans are lying (horizontal) for one third of a day to sleep, sitting for half of a day to work, and two-thirds of a day in vertical orientation (sitting, walking or moving). Consequently, it is very important to keep the body&#39;s spinal posture at a “minimum tension” configuration to have well sleep and comfortable seating to minimize fatigues, unfortunately, the principal focus has not yet been recognized by those of skill in the art which has relied upon cushioned or resilient support (so called foam supports) to relieve this pressure. Unfortunately, this related cushioned support often causes further detrimental pain. 
         [0008]    Further if body posture has been improper for a long period of time, the internal organs, such as a stomach, intestines and lungs, may be dysfunctional or limited in beneficial function. 
         [0009]    Referring now to  FIGS. 1 and 2 , a conventional chair  1 , even a very expensive chair, has a conventional waved shape  1 B back support in vertical direction to provide some comfortableness rather than a flat surface. In addition, some expensive chairs also have an open-U-shape  1 A in horizontal direction, shown along arch  1 A′ to provide a bucket-like or curving feature, which may prevent user&#39;s unintended body movement but unfortunately causes compression of the rib cage and pressure on internal organs and spinal column via force vectors  1 A″,  1 A″ positioned perpendicularly to the curve of arch  1 A′. 
         [0010]    Various attempts have been made to improve the noted detrimental conditions. In U.S. Pat. No. 4,529,247, the entire contents of which are incorporated herein by reference, the disclosure notes a one-piece shell chair with a tilt mechanism, but provides no rigid device for improving posture during sitting thereby limiting it as an effective solution to reducing pressure on internal organs. 
         [0011]    In U.S. Pat. No. 4,601,514, the entire contents of which are herein incorporated by reference, disclosed is a backrest with a back support which might improve the lower back of the user but not upper back. In addition, although a huge number of chairs have been introduced and made, the back supports of such chairs are flat or open-u-shaped, or a so-called bucket seat. Even a racing car driver&#39;s seat of which necessarily requires extreme tensions during use and for long time periods, is a very tight U-shaped bucket seat having a related arc (like arch  1 A′ in  FIG. 1 ) to minimize the body movement during race but fails to minimize spinal tension. The feature of such bucket seat may cause very strong stress to the driver&#39;s internal organs, particularly during the high gravitational loads applied during racing. 
         [0012]    In US Pub. No. 2008/0116730 disclosed are the thoracic back support allowing for and assisting in the promotion of scapular retraction in a seated human. Unfortunately this reference realizes minimal column-only support for the upper spine portion or proximity of scapular. Further, the back support portion of &#39;730 is flat and there is no force to push forwardly away from the spine as is discussed below. Accordingly, US &#39;730 may not provide any force forward to help the straight posture and improve lower back tension and pain by forcing the middle of back in a manner discussed. If any force added to the column in &#39;730 alone, the spine will be hurt due to direct back pressure on the spinal column itself. 
         [0013]    What is not appreciated by the prior art therefore is a back support system and method for improving the same wherein the method readily speeds generation of the system. 
         [0014]    Accordingly, there is a need for an improved back support system and method for generating the same.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0067]    Reference will now be made in detail to several embodiments of the invention that are illustrated in the accompanying drawings. Wherever possible, same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms, such as top, bottom, up, down, over, above, and below may be used with respect to the drawings. These and similar directional terms should not be construed to limit the scope of the invention in any manner. The words “connect,” “couple,” and similar terms with their inflectional morphemes do not necessarily denote direct and immediate connections, but also include connections through mediate elements or devices. 
         [0068]    Referring now to  FIG. 3 , a human back-shape is multi-dimensional, and includes an open-U-shape  2 L (a part of oval-shape torso extending away from and along the projecting spinal muscles), and also a shallow V-shaped cavity  2 K spaced between the projecting spinal muscles. Specifically, a horizontal human back-shape is not simple open-U-shape but is a waved-W-shape (from one side to the other with the center of the “W” being the shallow V-shaped cavity  2 K). 
         [0069]    Referring now to  FIG. 3A  a representative analysis of a force construction is noted relative to a spinal axis  100  as shown for a human user  101  having a head member (shown), and a torso boundary line (shown) as well as an exemplary rigid non-deflecting support device  102  according to the present invention. 
         [0070]    As will be noted, parallel sets of analysis along force lines f, f′ are determined as weight of body on opposite sides of spinal axis  100  pushing (while seated) onto the rigid non-deflecting support surfaces for device  102 . As will be noted a key is provided for the force vectors f, f 1 , f 2 , f 3 , f 1 ′, f 2 ′ and f 3 ′, as respectively shown in the diagram. It is noted that forces f 3 ′, f 3 ′ are the opposing resulting forces and the resulting vector sum of tangent forces f 2 ′, f 2 ′ are the outward forces f 1 ′, f 1 ′ which, due to their size, are illustrative of the rotational (opening) force exerted on the seated user  101  to open the lungs and torso cavity and result in less pressure (f 3 ′, f 3 ′) being pushed back into the user from the back support. In sum, forces f 3 ′, f 3 ′ are resulting in less or lowered pressure returning from the back support into the user due to the unique shape and size, and critically the rigidity or non-deforming nature of support  102 . Those of skill in the art, having studied the attendant disclosure in detail, will recognize that the rigid non-deflecting nature of support  102  enables the above force-analysis. Were support member  102  to be deforming it would be impossible to achieve the present results. As noted above, a deforming support would curve the torso of the user and would result in a contrary analysis. Referring now to  FIGS. 3B and 3C , a preferred support embodiment  102  is noted, and an additional extension support portion  102 ′ (see  FIG. 3C ) is noted. As depicted the preferred width is 260 mm (millimeters) and a preferred length of 500 mm, broken into a Zone A (100 mm) and a Zone B (400 mm), as shown. Each support  102 ,  102 ′ includes a front user-contacting surface  102 A and a rear chair-surface or bracing contacting surface  102 B. For example, during a use, supports  102 ,  102 ′ may be placed in a conventional chair (shown later) or against another bracing contacting surface which in turn contacts contacting surface  102 B, and being a non-deforming rigid member transfers this support to user-contacting surface  102 A. Measurements noted are as shown or are relative to these discussed surfaces. 
         [0071]    As will be noted a base surface  102 C is provided with a center height of 83 mm (preferable), and a top height of 95 mm (preferable) forming Zone A or the lumbar support portion. It is noted that Zone B is a mid-back support range. Necessarily, a parallel arc curve extends from outer perimeter of the 260 mm width to the apex and returns on the opposing side uniformly in an arc, which in combination forms an ‘arch’ for supporting the user&#39;s back. Beginning in Zone B, a top surface  102 D with a height of 50 mm (preferably) extends downward to meet the apex of 95 mm (preferable) at the beginning of zone A. As a result of the depiction and the illustrations in  FIGS. 3B and 3C  it will be understood that there is both a major curve Alpha from top and base surfaces  102 D,  102 C, and a minor curve Beta from side to side across the width of 260 mm (preferably). Thus, there are two principal curves that are smoothly blended together and may be understood by the dimensions noted and the below discussed ratios relative to the back-support surface  102 B and front surface  102 A. 
         [0072]    As noted in  FIG. 3C  and additional extension for upper back and neck, in Zone C, extends an additional 400 mm (preferably) to a narrowing arch having an apex at 34 mm (preferable) from support surface  102 B. 
         [0073]    Preferably, it will be noted, that with back support plain  102 B being a common plane among zones A, B, and C, that there is a recognized centerline “CL” along line  102 B′ that traverses the length of member  102  from zone A to zone C (after combination) and provides a reference for further discussion. A point at  102 B″ is the intersection between centerline  102 B′ and back support plane  102 B, allows a discussion of radi for generating an understanding of the curve limitations between outer points  102 B- 1  and  102 B- 2  along the outer edge of bottom plane  102 B (see  FIG. 3B ). These radi (R) details will be recognized as being between R=95 mm to 130 mm, in Zone A, between R=50 mm to 130 mm, in Zone B, and between R=34 mm to 130 mm in Zone C. Such that that the continuous curve (curve Beta) is formed by the arc-tangents between the two respective curves defined along the peak center line radius and the bottom plane radius. In this way a continuous convex curve is extended from point  102 B″ with a variable range of ratios forming the outer back-support surface. 
         [0074]    Additionally in this way, it will be realized that for Zone A, a height ratio from bottom  102 C (83 mm high) to top location  102 C′ (95 mm high) is 0.87(=((83−95)195)), so that the tapered reduction in the arc curve change (curve Alpha) or reduction of approximately 12.6%(=12 mm/95 mm) from the top location  102 C′. 
         [0075]    For Zone B, it will be recognized that the height ratio from top location  102 C′ (95 mm high) to the top plane  102 D of Zone B (50 mm high), is 0.53((=((50−95)/95)), so that there is a tapered reduction in the arc curve change (curve Alpha) or reduction of approximately 47%(=45 mm/95 mm) from the apex or highest curve position. 
         [0076]    For optional Zone C, it will be recognized that the height ratio from top location  102 C′ (95 mm) to the top plane at the end of Zone C (34 mm high), is 0.35((=((95−34)/95)), so that there is a tapered reduction in the arc curve (curve Alpha) of approximately 64%(=61 mm/95 mm) from the apex or highest curve position. It will additionally be noted that the ratio is approximately 0.32(=((50−34/50)) for the change from Zone B to Zone C and an arc curve change or reduction of approximately 45.7%(=((50−34)/34)) from the now apex of 102D at the top of Zone B. Therefore, Zone C provides a change between smooth curve from the apex at 95 mm to 34 mm and optionally a different curve from 50 mm to 34 mm (as shown). 
         [0077]    Referring now additionally to  FIGS. 3D and 3E , an exemplary embodiment is provided with a plurality of individual supporting members  300  extending from a defined vertical plane  301  supporting a chair embodiment (shown). Each individual supporting member includes a uniform separation distance S (shown as 30 mm preferably), and a respective length L (as noted). As will be understood from one skilled in the art following the above discussion regarding  FIGS. 3B and 3C , the respective lengths pursue the respective curves Alpha and Beta as defined in Zones A and Zone B. Each respective length L begins with a spacing distance (25 mm) from the defined support plane  304  as a beginning base support. In this way a specific difference and spacing interval may be followed to pursue the above noted ratios, curve radi, and other specifics. As will be noted in this preferred embodiment, measurements for specific distances from a supporting floor or a seating level in the chair are provided to fully detail the locations relative to a desired user. 
         [0078]    Referring now to  FIGS. 4 through 7 , another embodiment of a back support of a back support device  3  is provided including projected portion  3 A from the surface of a back support board extending vertically as  3 C. The extending line is one of waving or straight line, but in either case provides a linear plain of extension from the supporting floor and as shown in a W-type support, is adapted to this supporting extending surface in a pleasing manner. 
         [0079]    As earlier discussed, and noted again here, in  FIG. 5 , it is obvious that projected portion  3 C extends from back surface  3 A. Further now in  FIG. 6 , the top view of the embodiment shows projection  3  from the back support surface  3 A and waving portion  3 B which is higher than the staring projection height in order to provide more ergonomic shape and comfortableness, as earlier discussed. Referring to  FIG. 7 , projection height of  3 C is in the range of 10 mm through 200 mm spaced from the defined vertical line. Preferably the projection height is in the range of 20 mm through 180 mm and further preferably in the range of 30 mm through 150 mm. The angle of the slope in  FIG. 7  is in the range of 5° through 30°, preferably 10° through 25° and more preferably 12° through 20°. 
         [0080]    In Table 1, the feelings and physical impressions are provided in a comparison chart between the present Embodiment 1 and a comparison conventional chair as in  FIG. 1 .

         [0081]    Referring now to  FIG. 8 , another embodiment of a portable back support system  400  is shown with a basic back support structure member  401  that may be readily applicable to a variety of uses and products. The portable back support system  400  may be fixed to a chair with an appropriated device such as a belt (not shown in Fig.) and/or incorporated into such as a car seat (shown later in  FIG. 14 ) or back support back pack (shown in  FIG. 18 ). Further portable back support is made of rigid, hard or substantially-rigid material like wood, resin, plastic, rigid foam and metal, but not limited, to avoid flattening the structure of the back support during a use. 
         [0082]    Referring now to  FIGS. 9 ,  10  and  11  showing a side view, a front view and a top view of another embodiment  450  in a chair  452 , wherein the ridge line  451  of the project portion in the side view is extending from the lower back to the upper back. The size of the back support is shown in the front view is almost covering the entire back portion with a wave structure. The structural feature of the back support of the present invention is further presented in the top view, noting the above-discussed arcs, curves, and construction. Specifically, the structure of the back support of the present invention is completely different from any conventional back support having a flat or a concave structure. 
         [0083]    Referring now to  FIGS. 13 and 14 , a third embodiment of a car seat of a back support device is provided in response to a conventional seat in  FIG. 12 . A prior art of a car seat is shown in  FIG. 12 , in which the seat is compressible foam to restrict the body movement for safer driving or even race driving and to cushion or absorb the force of supporting such a body. In contrast to the conventional construction, in  FIG. 13 , an embodiment  470  of a seat provides a seat having projected center portion  472  in vertical direction on the surface of back support. While seating and driving, a driver may receive an ‘opening’ force and consequently less stress on the back and internal organs. It shall be recognized here that the support member depicted may be constructed from a single shaped support (monolithically formed) or from a plurality of articulated separate support shapes retained relative to the unit and allowing relative sliding or shifting and motion there between adjustable to a particular users need. It is easily predicted that many professional drivers including taxi driver and long-distance truck driver are complaining of stomach complications and fatigue because of very long driving may be relieved using Embodiment 3. 
         [0084]    In  FIG. 14 , the explosive view of the embodiment is provided, wherein in the element of the back support of the present invention can be prefabricated in the car seat or be attached as a portable or removable device by a user. A prefabricated seat is not limited to the car seat, and can be a seat in an airplane, a theater, a school and any other type of seat where human will seat. 
         [0085]    In Table 2, the driving test results are provided in a comparison chart between a conventional car seat and conventional car and airplane seats with a portable back support according to the construction of the present invention. The user who tested the back support of the present invention has been suffering from chronic lower back pain and difficulty to see front-upper portion ranges while driving due to spinal-curved visional problem occurring on the older person.

         [0086]    Referring now to  FIG. 15 , an additional embodiment of a lumber back support system  800  includes rigid projected portion  801  inside a retaining pocket  801 A (shown held in place by a fabric layer with grommets), of a wide belt member  802 . A releasable closure system  804  on either end of belt member  802 , preferably a hook-and-loop closure system like Velcro® is employed to allow a user to employ the belt system  800  around their torso during use, either in their clothing or outside their clothing. In this way, the same support member discussed above may be adaptively employed in a back support system for improved user-convenience. 
         [0087]    Referring now to  FIGS. 16 ,  17 , and  18 , an additional embodiment of a back pack system  810  includes a back support system  811 , of the present invention on the back with shoulder belts  812 . In  FIG. 18  is a exploded view of the embodiment notes back support system  810  comprising a front portion  813  including the shoulder belt  812 , back support  811  and a flexible slide cover  814  such as a nylon pouch, and an outer rear portion  815  containing a variety of goods and books and so on and joinable with member  813  via a zipper system  816  as a combined unit or kit  810  which can be used also as an portable back support of the present invention by attaching to a chair or any other back support without the back support of the present invention. As will be understood rear portion  815  is a compartment. Both of portions  815  and  813  are combined to make an back pack system  810  which is more comfortable while carrying because of force-to-front effect of back support  7   c.    
         [0088]    Referring now to  FIGS. 19 through 22 , additional embodiments are depicted as chairs with back support device including a neck-rest means are provided. A neck-rest embodiment  900  of the embodiment is presented with a neck rest region  901  that will provide additional neck-spine support as shown. Embodiment  900  may improve user&#39;s conditions whose neck or around neck difficulties has complications such as cervical spine injury and whiplash injury. In  FIG. 20 , a person/user  903  who has a cervical injury is seating on an expensive conventional chair  904  and as will be noted a defined neck-spine axis  905  is not parallel to a body-spine axis  906 , at a relative angle alpha α. This off relative angle alpha α results necessarily in poor neck support and pain. In contrast, see  FIG. 21 , the same person  903  is seating on a back support chair  907  with neck-rest portion  901  and a defined neck-spine axis  908  is parallel with a body-spine axis  909  allowing for comfortable support while employing the same Zone A and Zone B construction as earlier noted. 
         [0089]    Referring additional to  FIG. 22 , as will be appreciated by one of skill in the art having read and understood the present disclosure, if a person sits on a conventional chair  910 , in  FIG. 22 , the individual person&#39;s neck will not naturally position in a straight line (neck-spine axis  910 ) with the spinal axis  911  (the overall direction of the spine, and not required to be literally a straight line axis) because the head is heavy and easily falls toward frontwardly so that any neck-rest would not help the neck being straight necessarily creating a stress angle a, as noted above. In contrast, a person seating on the embodiment noted in  FIG. 21  may keep easily the straight-up body posture, in which a neck-rest works unexpectedly because a chest and a throat are naturally in open an state thereby also improving breathing and minimizing snoring during sleeping. According to these results, the present invention may provide not only comfortable seating or lying pose but also may provide a neck-rest workable naturally. 
         [0090]    Referring now to  FIG. 23 , another alternative embodiment of the present invention  920  includes back support system  921 , a neck-support portion  922  having a height adjustable arm system  923 , allowing a neck-rest member  924  to adjust relative to back support system  921 . In this way, embodiment  920  may be individually optimized in accordance with user&#39;s length between hip and neck. 
         [0091]    Referring now to  FIG. 24  an additional embodiment includes a back support member  925  secured to a chair  926  and a movement stopping member  927 . Movement stopping member  927  projects upwardly away from a seat support surface to interfere between a user&#39;s legs as a wedge. In this way, the movement stopping member  927  prevents the hip portion of a user from moving forward (away from support  925 ), and keeps a user&#39;s body-shape correctly without giving stress to the body. 
         [0092]    The present invention may not be limited to the embodiments noted above and may be applied to a variety of back support or pose correction devices including a bed, a mattress, a floor mattress, a back support for lifting heavy materials, a corset for shaping up and/or correction of defected body without departing of the present invention&#39;s spirit. 
         [0093]    Referring now to  FIG. 25  an additional embodiment provides an adjustable system  980  for personalizing a back support system  981 . As depicted, a plurality of individual moveable members  981  are formed in an undulating shaped manner according to the present invention, each respectively have substantially the same size and shape, but being independently movable according to a user need along both a support axis direction T and laterally from the support axis along a direction L to provide contacting pressure on a user&#39;s spinal column (e.g., two dimensional adjustment motion). Respective pieces are movable back and forth to be adjusted to use&#39;s back shape. When the position is determined, each piece is fixed with a securing system  985 , shown as a threaded screw member. Respective pieces are held by such rubber bands or other temporary means during a fitting process until a user is satisfied of matching their personalized back physiology. A vertical support member  986  extending from a back of the chair member  987  provides additional stability during the set-up process for each user. Following the set-up process, a fully constructed chair (like that shown in  FIG. 3D ) may be constructed from the now arranged measurements. 
         [0094]    Referring now to  FIG. 26 , a pictorial representations of a plurality of support members  990  having the noted dimensions L 1  (220 mm), L 2  (80 mm), L 3  (50 mm), L 4  (60 mm) are provided and may be spaced along the upright support member  991  on a chair base  992 , to construct a chair system about a centerline (CL), as noted. In each reference number the distances are measured in mm (millimeters) and as a consequence, incorporating the known detail from above, a full chair support system  995  may be constructed by adding a respective plurality of individual undulating support members  990 . 
         [0095]    As used herein, those of skill in the art having read and understood the above disclosure will recognize the use of the phrases rigid or fully-rigid or non-resilient or non-deflectable as being descriptions under normal or expected human body forces. For example, a 400 lb adult male user resting on a chair may exert approximately 60 lbs to 80 lbs of backward or back-support force along a vector perpendicular to the user&#39;s torso and directly into the support—under this type of force the back support is to be non-moving or non-deflectable from an original shape and form as discussed and claimed herein. This type of use is in full contrast to any previously recognized support systems which attempt to employ a deflectable cushioned member to urge support—necessarily during use these previously recognized support systems deflect from their original supporting shape. 
         [0096]    In the claims, means- or step-plus-function clauses are intended to cover the structures described or suggested herein as performing the recited function and not only structural equivalents but also equivalent structures. Thus, for example, although a nail, a screw, and a bolt may not be structural equivalents in that a nail relies on friction between a wooden part and a cylindrical surface, a screw&#39;s helical surface positively engages the wooden part, and a bolt&#39;s head and nut compress opposite sides of a wooden part, in the environment of fastening wooden parts, a nail, a screw, and a bolt may be readily understood by those skilled in the art as equivalent structures. 
         [0097]    Having described at least one of the preferred embodiments of the present invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes, modifications, and adaptations may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
