Abstract:
A chair having two body supports which move in similar rotation and inverse elevation to one another to change from a chair configuration, where one support is higher than the other, to a spine tensioning apparatus, where the supports are near equal in elevation. Preferably body supports are spaced apart from one another such that the only interconnecting human link between the two supports, when in a near equal elevation configuration, is the human spine. The spine, in this configuration is then subjected to similar forces as a simple beam supported by two separate forces, tension, compression, shear and moment. The spine is aided by and through tension and contraction and increased blood flow and afforded the ability for spinal muscle, nerve and soft tissue development and maintenance. The supports, independent of each other, comprise an upper body support and a lower body support and allow an individual&#39;s body to practice spine enhancement, development, &amp; or traction, laying or any combination of, or alternately, face up, face down, or on either left or right side. The apparatus is also be applicable to retrofitting existing chairs.

Description:
This application claims benefit of Provisional No. 60/027,767 filed Oct. 4, 1996. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates generally to devices used in physical therapy and, more particularly, to a spine tensioning, traction and muscle exercise apparatus. 
     Back pain is a national health problem. It is the second most likely reason people go to the doctor. It is estimated Americans spent $20 billion alone in 1990 on back-related medical bills. More and more people sit for hour upon hour and perform computer work. Studies show that sitting creates two times the pressure on the low back as compared to standing. 
     Numerous devices have been devised to help with this problem, including the following: 
     U.S. Pat. No. 4,793,665 to Kvalheim discloses a chair with a seat rest and separate backrest. However, it cannot provide spine tensioning because it supports the user&#39;s posterior. 
     U.S. Pat. No. 4,432,108 to Chapman, U.S. Pat. No. 2,2,48,369 to Laudersen and U.S. Pat. No. 2.112,678 to Rausch all teach leg supports, but do not teach spine tensioning. 
     U.S. Pat. No. 5,042,800 to Walter teaches a spine tensioning body support whereby the user&#39;s back and legs are supported but not the posterior. The four vertical risers and two elongated members are fixed and require dismounting and disassembly to change leg and back support location. Additionally, the users must support themselves with their arms on the elongated members and lift one leg at a time over the leg rest to place them in the device. This feat is difficult for some users and may prohibit older users and those with back pain from obtaining the benefits of the device. 
     SUMMARY OF THE INVENTION 
     It is thus an object of this invention to provide the user a simplified access for practicing spine tensioning, traction and development. 
     Another object of this Invention is to provide an economical means to practice spine tensioning, traction at a minimal cost without the aide of a therapist. 
     Still another object of this invention is to provide a device, which may readily be utilized as a chair and, with no structure adjustments, nor dismounting also function as a dual support spine-tensioning device. 
     Another object of the invention is to provide the user with an opportunity to vary and increase the mild limited tension to the spine by allowing the user to lay face down in the apparatus. 
     Another object of this invention is to provide a chair that, in the reclined position, decompresses the low back as opposed to doubling the pressure when sitting upright. 
     Still another object of this invention is to provide a computer input chair that may also function as a spine tensioning computer input chair from which one may still be able to perform computer related tasks. 
     BRIEF SUMMARY OF THE INVENTION 
     These and other objects of the invention are accomplished by a spine tensioning dual body support chair that includes two substantially planar body supports that rotate in similar direction and opposite elevation to one another. A rotating means will move body supports in similar rotation and opposite elevation to one another. Preferably, body support rotating means will have two end limits which will hold the body supports in a chair position, one support higher than the other, or in a spine tensioning position, both body supports in near equal elevation. Rotating means may also be fixable so that body supports may be fixed in any rotation or elevation to one another so desired to perform various spine tensioning, traction or developing exercises. These body supports will support the human body with different reactive forces depending on their relative elevations, rotational position and distance from one another.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIG. 1, the apparatus comprises a base member  2 , consisting of two parallel elongated horizontal base members, two vertical risers, and a horizontal base member perpendicular to and connecting the two elongated horizontal base members. Body support elevation arms  14 ,  14   a  are elongated members pivotally mounted to base member  2  via pivot connection  26 . Dual body supports,  18  and  22 , are pivotally mounted to body support elevation arms  14  and  14   a  via support rods  32  and  34 . Hand grips  10  and body support elevation limit blocks  24  and  24   a  are attached to base member  2 . 
     FIG. 2 shows a user in the sitting position. The elevation of body support  18  is higher than body supports  22  creating a chair or seated position. A fixed, stable seat is created when body support elevation arm  14  rests on body support elevation limit block  24 . 
     FIG. 3 shows the user in the reclined seated position dual body supports at near equal elevation. A fixed, stable, reclined position is the result of body support elevation arm  14  resting on body support elevation arm limit block  24 . Hand grip  10  enables the user to change from seated to reclined position via a light force. Pivot  26  is placed near center of body support elevation arm  14 , between rods  32 ,  34  such that body support elevation arm  14  will rest in either the seated or reclined position. 
     FIG. 4 shows the user in a horizontal position body supports near equal in elevation. Body supports  18  and  22 , pivotally mounted to rod  32  and  34 , enable this positioning. 
     FIG. 5 shows the user enabled to perform gravity assisted inverted stretch with body supports near equal in elevation. The body mass distributed on the A side of body supports creates this gravity assisted stretch by placing an upward force to the mid section of the body via resulting B pivot force. 
     FIG. 6 demonstrates dual body supports, near equal in elevation, user lying face down. The lever arm of users legs L about pivot  32  creates a greater traction force T than is achievable in FIG. 3, user face up. This is because FIG. 3 traction force is not increased via lever arm L of FIG.  6 . Additionally, the resulting force T of FIG. 6 is directed to the lumbar portion of the spine where a majority of back discomfort occurs. FIG. 3 on the other hand is gravity induced only. 
     FIG. 7 shows body support elevation limit block  24  with its two limits: for sitting,  246 , and for reclining,  244 , that produces a fixed seat position S or fixed reclined position R. 
     FIG. 8 shows the upper body connecting block  180 . with travel range created by void  182  that allows support rod  32  to move freely within void  182 . Arm support  184  provides an arm rest that doubles as a means to provide the user a means to counteract the gravity forces that create spine tensioning. Neck rest  186  is pivotal mounted to upper body support VIA pivot  188 . Pivot  188  allows 360 degree movement of neck rest support  186 . Neck rest  186  has the ability to work in combination with armrest support  184  to match the gravity forces generated when the back support is positioned such that traction/gravity is acting on the upper body. All or half or combinations thereof of the gravity forces acting on the upper body may be countered with these supports. 
     FIG. 9 teaches another means for establishing fixed elevation relationships between the two body supports via limit block  264 . This body support elevation relationship block is adjustable through adjustment holes  260  to fix and hold body support elevation arm at any desired body support relationship. 
     FIG. 10 shows the connecting block  220  with void  222  that allows rod  34  to move freely within the void. 
     FIGS. 11,  13 ,  15  and  17  show alternate body support elevation relationship varying means. FIG. 11 is a typical stack able chair consisting of a base  2  with four support risers  202 . FIG. 13 is a rocking chair with rounded bottom end  209 . FIG. 15 is a wheelchair. FIG. 17 utilizes ropes supported by rollers above. All above FIGS. 11,  13 ,  15 ,  17  utilize dual body supports  18 ,  22  and a form of the body support elevation relationship varying means  26  and limit blocks,  246  for sitting, and  244  for reclining. 
     FIG. 12 shows an alternate mounting block that has void  182  that allows leg support  22  to rotate in any direction. 
     FIG. 14 shows the ranges of motion A and B for either upper body support  18  or lower body support  22 . 
     FIG. 16 shows the A and B movements of either upper body support or lower body support in relation to rod  34 . 
     FIG. 18 shows an office chair base  2  for mounting dual body support elevation arms  14  via pivots  26 . FIG. 19 shows alternate dual body supports  18  and  22  that are substantially planar with convex cross section. FIG. 20 shows an alternate enhanced chair for spine developing, tensioning and development. It comprises a base member  2  that consist of two upside down u shaped members that are interconnected and made stable by members  244  and  246  that also serve as limit blocks  246  and  244 . Positioning means  14  assumes a 90 degree fixed position as opposed to the elongated members  14  of FIG.  1 . Upper body support  18  is fixedly mounted to positioning means  14  canceling the need for rods shown in FIG. 1 as does the fixed lower body support  22  cancel the need for rod  34  shown in FIG.  1 . Pivot  26  performs the same function as  26  of FIG. 1 allowing the positioning means  14  to assume either a sitting position or a reclined position in FIG.  11 . Alternately upper body support and lower body support could be pivotally mounted in the alternate base mode FIG. 20 to provide the same benefits to the user as taught in FIGS. 4 and 5. Benefits to the user in the alternate base mode FIG. 20 are equal to those taught by FIGS. 3 and 4 with fixed upper and lower body supports as shown in FIG.  22 . To gain the benefits of this enhanced chair for aiding the spine one sits in the chair and reclines. By reclining the body weight is distributed over two supports. This places the human spine under the same member forces as a simple beam supported by two vertical forces, it produces tension and compression. The human spine is undoubtedly the most important muscle bone structure in the human body. Chiropractic teaches this and anyone realizes the many functions of the spine. Simply supporting the human body in two different places with the only human link between the supports places the spine subject to any number of forces in any number of directions. It is this placing the human spine as the only human link between the two vertical supporting forces that enables one to practice exercise of the spine. 
     Referring to FIG. 21, body supports  22  and  18  are shown as floats to be utilized in a pool or body of water to practice another mode of dual body support spine tensioning. The water  14  acts as the dual body support elevation relationship arms  14  of FIG.  2 . 
     Referring to FIG. 22, dual body support elevation relationship arm  14  is set with body support  22  higher than body support  18  to facilitate sit ups and alternate directional forces on the spine. 
     FIG. 23 teaches slide able mounting of rod  32  to arm  14  of FIG. 1 as a preferred alternate. Position is fixed via pin  160  into holes  162  into arm  14 . This allows for easy adjustment to accommodate the varying user&#39;s height as required. A clamp means would also be applicable here. This connection could also be slide able with user in device to create another exercise range for the device. 
     FIG. 24 represents the dual body supports weight transfer from one support to the other as rotation and elevation changes occur. The support locations shown in FIG. 24 a  depicts the full 100 pound user load on the lower support. In FIG. 24 b , the user&#39;s load is distributed 70/30 and in FIG. 24 c  it is 50/50. In FIGS. 24 d  and e, the user&#39;s weight continues to transfer until the full user weight is carried by the body support of FIG. 24 a  that had no load on it. This, in combination with the moment and shear drawings, is what distinguishes this device from a traditional chair. The dual body supports in this invention can take a user from a seated position and place their body subjected to two forces that are spaced apart and create beneficial forces to the skeletal system. 
     Referring to FIG. 25, shear and moment diagrams are shown for simple beams with two supports. What is important about these diagrams is the way shear and moment forces change, as a result of supports location change. Body support location changes have similar effect on the user&#39;s body and spine. The two supports are created in the Dual Body Support spine-enhancing chair. Varying support locations under a simple beam/user, supported by two supports, creates different shear, moment, compression and tension forces, induced in the supported beam/user. The ability to adjust the dual body supports&#39; horizontal distance from each other, as well as their relative elevation and rotation positioning enables any number of force combinations; compression, tension, shear and moment, to be applied to the spine and skeletal system. This enables the dual body support spine-enhancing chair to increase spinal mobility, flexibility and health through a rotatable dual body support means.

     FIG. 62 displays an alternate version of positioning means  14  with springs  564  incorporated to create a spring like resistance to movement of rod  34 . 
     FIGS. 63,  64 ,  65  all displays the same positioning means  14  with flat bar  224 . What is significant is the gravitational effect when the user is supported in these three different figures. 
     In FIG. 63 the pivots  228  are directly above leg support  22  and back support  18 . 
     In FIG. 64 pivots  228  are extended and create an increased volatile tension on the body due to gravity acting on flat bar  224 , attempting to cause it to hang vertical. 
     The opposite body effect, compression is created when flat bars  224  are moved inwards of FIG.  63 . 
     Flat bar  224 &#39;s rotatable connection to positioning means  14  in FIGS. 63,  64  and  65  allows dynamic movement of lower back support  22  and upper back support  18 . 
     In FIG. 66 positioning means  14  has a rope or rubber element  604  connecting to and supporting upper body support  18  and lower back support  22  enabling these body supports any horizontal movement and also with resistance if  604  where rubber or elastic. 
     Referring to FIG. 67 foot support  614  is pivotally mounted via pivot  618  to arm  616  that is slide able mounted to lower body support  18  via slide  612 . This enables the user to extend foot support  614  and lock slide  612  so the users heels will rest beyond foot support  614 . Once in this position the user may obtain tension and muscle exercise from neck support  186  continuously down through the body to the ankles. Contracting one ankle cause the other ankle to be extended via pivot  618 . 
     Referring to FIG. 68 an alternate version of leg support  614  or FIG. 67 consists of ankle supports  624  that may be tubular in shape and U shaped to receive users heels and fixedly attached to heel rest  614 . Additionally pivots  628  may be utilized to allow foot rotation as shown in the A or B direction. 
     Referring to FIG. 69 a plan view is shown of an alternate lower body support  22  and upper body support  18 . Pivots  632  enable substantially planar support members to rotate in clockwise or counterclockwise direction. 
     Referring to FIGS. 70,  71  and  72  the planar upper body support  18  and lower body support  22  are shown at varying elevations to each other by alternating height of pivot  632 . 
     Referring to FIG. 73 an alternate use of the instant invention shows the user able to mount the apparatus face down, to reverse the spine stimulation/forces obtained when using the apparatus. 
     Referring to FIG. 74 a force diagram displays the counteracting forces to keep the user in a static position. Notable is the neck force N (at one end of the spine) and the lower arm force that is transferred into the upper body support  18 . 
     FIG. 75 demonstrates the users ability to perform sit ups via slides  544  of FIG.  60 . 
     FIG. 76 demonstrates the users ability to flatten their body into a horizontal plane, hips higher then FIG.  75 . 
     FIG. 77 displays the user with hips in a higher position than FIG. 76, and the ability to further extend upper body support  18  via slide opening  710 . It is the users hip movement from FIGS. 75 to  77  to  77  and back to FIG. 75 that is very therapeutic to the spine. 
     Referring to FIG. 78, the user is shown in the apparatus moving in direction A with resulting hip in the C motion. Additionally what is significant in FIG. 78 is back support  18 &#39;s pivotal motion around pivot  32 , such that as the weight increases to the right of pivot  32  an opposite uplifting force occurs to the left of  32  via back support  18 . 
     Referring to FIG. 79 an alternate neck support  186  is shown with hand grips  730  attached thereto. This enables skeletal forces to be transferring from hand grips  730  through users arms to users spine and thoracic vertebrae. 
     Referring to FIG. 80 another alternate means of the invention is shown where the lower body supports  22  are independently mounted to gear driver rods  740 , which in turn rotate axle  742  to power wheel  744 . 
     Referring to FIG. 81, two different height individuals are shown on the upper body support  18  and the lower body support  22 . What is significant about the two individuals of daring heights is that no modification is required to upper body support  18  nor lower body support  22 . The only difference required to accommodate the individuals height difference is only a greater A dimension for the taller individual. 
     Referring to FIG. 82 an alternate version of neck support  186  is shown connected to pivot  188  which allows neck support  186  up and down rotation. 
     Referring to FIG. 83 a plan view of neck support  186  is shown whereby pivot  188  allows the user to turn their head side to side. Note that FIG.  82  and FIG. 83 may be combined to produce each affect simultaneously. 
     Referring to FIG. 84 the user is shown in a reclined position. What is important is the dimension L over which spine tensioning compression and twisting may occur. It extends from neck support  186  down through heel support  614 . 
     Referring to FIG. 85 an alternate means of the apparatus is shown. The lower body support  22  and upper body support  18  are positioned to provide an unsupported distance D of FIG.  86 . Thus creating an upper body support and lower body support which are connected only by the spine so that independent movements of either body support will be transferred via the spine. 
     Referring to FIG. 87 a contoured version of back support is shown. This may be a felt or plastic molded member. 
     FIG. 88 displays front view of FIG.  1 . Base  2 , positioning means  14 , pivot  26 , lower body rod  34  are shown. What is significant of these three different views is different horizontal plain variances of the upper and lower body supports which enables the user to twist the spine longitudinally along its length promoting spine health through, compression, traction, muscle development and increased blood flow. 
     Referring to FIG. 89 an alternate version of the instant invention is shown with tubular round guides slidabley connected to lower body rod  34  and upper body rod  32  to enable 360 degree rotation of upper body support  18  and lower body support  22 . 
     Referring to FIG. 90 alternate pivot  8800  with nut  8840  enables the tensioning of positioning means  14  to be set so that, with a balanced lower body rod  34  and upper body rod  32 , the positioning arm  14  will hold user in any position from sitting to reclining and allow changes in rotational position with minimal effort/force on hand grip  10 . 
     Straps  8900  shown in FIG. 91 would be of nylon or similar material to retain user in position while partially or fully inverted. 
     Referring to FIG. 94 shown is another alternative embodiment  800  of the present invention. In this embodiment  800 , the collapsible frame  810  comprises a leg support frame  820  and a back support frame  850  joined together by a positioning means for positioning the leg support frame  820  and the back support frame  850  appropriately so that a user&#39;s posterior will not be supported, preferably a longitudinal member  890 . The leg support frame  820  comprises an elevated leg support member  822  joined to vertical leg support legs  824  and  826  by elbow joints  828  and  830 . The longitudinal member  890  is joined to the elevated leg support member  822  by a T-joint  832  Two pulleys  834  and  836  are preferably mounted on the elevated leg support member  822 , preferably on opposite sides of the T-joint  832 , and preferably adjustably spaced apart from each other. A leg support rope  838  preferably is run between the pulleys and preferably V-shaped leg supports  840  and  842  are suspended from the ends of the leg support rope  838  by a triangular trapeze arrangement so that the underside of a user&#39;s knees can contact the leg supports  840  and  842 . Thus, downward movement of the left leg support will cause equal upward movement of the right leg support and vice versa. The back support frame  850  preferably comprises an elevated back support member  852  joined to two vertical back support legs  854  and  856  by elbow joints  858  and  860 . The longitudinal member  890  is preferably joined to the elevated back support member  852  by a T-joint  862 . Two pulleys  864  and  866  are preferably mounted on the elevated back support member  852  on opposite sides of the T-joint  862  and adjustably spaced apart from each other. A hand grip rope  868  is preferably run through both pulleys  864  and  866  and hand grips  870  and  872  are preferably suspended from the ends of the hand grip rope  868  by a triangular trapeze arrangement. Thus, downward movement of the left hand grip will cause equal upward movement of the right hand grip and vice versa. Preferably a back support  874  is suspended from the hand grip  870  and  872  by back support ropes  876 . Preferably, the elevated leg support member  822 , the two vertical leg support legs  824  and  826 , the elevated back support member  852 , the two vertical back support legs  854  and  856  and the longitudinal member  890  are adjustable in length either through being telescoped or through the use of joints that would allow attachment of the various members and legs to each other at points other than their ends. Preferably also, these members and legs are rigid piping of a material such as metal or plastic and have a circular or square cross-section. Preferably, the leg support ropes  838 , hand grip rope  868  and back support ropes  876  all comprise a strong, light, durable rope, such as nylon rope. The pulleys  834 ,  836 ,  864  and  866  can be a conventional construction as can the elbow joints  828 ,  830 ,  858  and  860  and the T-joints  832  and  862 . The hand grips  870  and  872  preferably comprise a cylindrical cushioned material for comfort. With the construction, it can be seen that the device is easy and economical to manufacture, ship and store, and easily assembled and collapsed by the user. The device also allows the user to turn his body sideways and to create tension along different lines of the body. 
     Referring to FIG. 95 shown is still another embodiment  900  identical to the embodiment of FIG. 94 but without the back support ropes or back support. 
     Referring to FIG. 96 shown is still another embodiment  920  non-stretching strap  922  is mounted between the hand grips  870  and  872  and the back support  874 , instead of the back support ropes  876 . 
     Referring to FIG. 97 shown is an embodiment  930  identical to the embodiment of FIG. 95, except that a flexible non-stretching strap  932  has been suspended between the hand grips  870  and  872 . 
     Referring to FIG. 98 shown is the manner in which a user would use the embodiment  930  of FIG. 97 by resting his or her neck on the strap  932  while the user&#39;s legs are retained by the leg supports. 
     Referring to FIG. 99 shown is an alternative embodiment  940  in which the leg supports are replaced by a leg support bars  942  and  944 , preferably of cylindrical cushioned material similar to the hand grips  870  and  872 . 
     Referring to FIG. 100 shown is a side view of a user using the embodiment  940  and FIG. 99 for rotational spinal tension, with only the hand grips  870  and  872 , leg support bars  942  and  944  and ropes  838  and  868  shown for clarity and the user&#39;s feet engaged with the leg support bars. Alternatively, the user can engage the leg support bars with his or her knees or other parts of his or her legs. 
     Referring to FIG. 101 shown is an alternate rigid contoured back support for use with all the preceding embodiments. Referring to FIG. 102 shown is an end view of the user using the embodiment  940  of FIG.  99 . Optionally, for greater strength and stability, additional longitudinal members can be added between the leg support frame  820  and the back support frame  850  of any of the preceding embodiments in order to provide additional bracing. Other additional bracing can be provided, such as anchored wires or additional reinforcing members, attached to various portions of the leg support frame  820 , the back support frame  850 , or the longitudinal member  890 . 
     Referring to FIG. 103 neck support  186  is equipped with nylon or similar straps that may be utilized for securing and retaining the users head in the neck support. This increases the amount of tension that may be created from the neck down. 
     FIG. 104 shows a upper body support that is connected to pivot  36  to base member  2 . This alternate version enables facilitation of spine movement due to the A movement of the user&#39;s weight over pivot  36 . 
     Referring to FIG. 105 an alternate version of the teaching of the instant invention is shown with three independent supports, lower  22 , middle  201 , and upper  18 . These three forces may be applied under the body to create any one of a variety of force, moment and shear forces as indicated in FIG. 25 by adding the third force or support. 
     Referring to FIG. 106 the upper body support is positioned to create shear forces on the hips to facilitate spinal movement and correction of individuals who suffer from spondylolisthesis. 
     FIG. 107 indicates how the forces of FIG. 106 may be applied, from the bottom Au, from below or above, Afa via ropes or hangers. Dv, shows the distance of the miss aligned spine, that AFu attempts to help correct or assist. 
     Referring to FIG. 108 an alternate upper body support is shown. Planar members  1112  are rounded and oblong and connected via clips  1114 . These supports  1112  are designed to permit as near complete movement similar to the spine itself, vertebrae by vertebrae. These spine like supports may be supported in any number of ways either from ropes  1110  or from below. 
     FIG. 109 shows an alternate of FIG. 112 whereby casing  1120  is adjusted by grip  1130  that rolls in track  1138  along  14  in opening  1142 . 
     FIG. 110 and 111 show how the user may practice upper body support only and facilitate the forces on ones body by adding the vertical hand grips  1150  to body support  20  that enable lever arm forces to be generated and transferred to the spine. Additionally important is the pivot forces that may be created about pivot  26 . User weight to the left of  26  will cause a raising force to the right of  26 . Preferably pivot  26  will be equipped with any number of means available today to create locking and holding of  20  as it rotates degree by degree in the counter clockwise direction. Preferably the pivot  26  would lock after every increasing degree movement in the counterclockwise direction and remain locked until a button or similar switch were activated on the hand grips  1150 . This apparatus will allow a user to walk up to it and grab hand grips  1150  and rotate forwards and be retained in the counterclockwise rotation and continue to rock in that direction until their feet or heels became elevated,  26  would lock and the user could practice spine exercise with heels just off the ground so as to create tension along the spine. At which time user is ready hand grips  1150  would have a switch that could be activated which would release  20  to rotate clockwise which would return the user&#39;s feet to the ground. 
     Referring to FIG. 112 the natural movement of the body is shown when they rotate when sitting. The user &#39;s upper rotates right and their lower body moves to the left. The instant invention immolates these natural motion as shown in application of FIG.  88 . 
     FIG. 113 shows an expanded body support  4  similar to  20  of FIGS.  110  and  111 . Pivot  26  preferably has the same rotate and lock increments, as well as releasing ability of FIGS. 110 and 111. 
     FIGS. 114 and 115 teach a hinge mounting of body supports. The hinge mounting will not allow the upper body support to rotate any further counterclockwise in FIG. 114 that would allow the user to fall through, yet it allows rotation of upper body support in the clockwise direction, FIG. 115, which benefits the user. Additionally and for the same reasons hinge  1180  is utilized at the lower body support. While it may have hinge pivot in the wrong place in FIG. 114, if it were switched with hinge pivot on other side it could be easily seen how it would provide the similar function of the upper body hinge in FIG. 114, stopping the user from falling through the supports and allowing for rotation in horizontal position. 
     Referring to FIG. 117 the arm  14  is positioned near vertical that will allow an older individual easy access as both upper and lower body supports are in the near vertical plane, like leaning up against the wall. This makes it easier for them to mount the device by eliminating the drop to the sitting position, rather they are taken from a standing position to a sitting or horizontal position by supports  18  and  22  connected to arms  14  to pivot  26  to base member  2 . 
     FIG. 118 teaches a seat similar to the lower body support of previous figures. What is important about this lower body support is its ability to function as a resting plane VIA pivot  1240  and pivot limit device  1244 . Yet when user wants to get out of chair they simply rotate forward and pivot  1240  allows lower body support  22  to rotate counterclockwise yet limit device  1244  will stop clockwise rotation.
