the inventive reclining traction chair 10 is shown in fig1 - 3a , 3b which has the appearance of a typical “ recliner ” and could be used as such . the chair 10 has a padded seat 12 , a padded backrest 14 , padded armrests 16 located on either side 18 , 20 of the padded seat and a padded footrest 98 . the padded seat 12 has a front side 22 , left and right sides 24 , 26 and a rear side 28 . the padded backrest 14 includes a top 30 , bottom 32 and left and right sides 34 , 36 , a head pad 38 and a back pad 40 ; near the sides 34 , 36 of the backrest 14 . between the head pad 38 and back pad 40 are gaps 42 to allow the shoulders space to fall into during traction . by relieving pressure on the shoulders , the chest of a user opens up and relaxes during traction . fig4 shows a side view of the chair 10 with a user 44 seated therein and using the chair 10 in normal fashion . in fig5 , the user 44 has decided to actuate the traction capabilities of the chair 10 and as shown , the backrest 14 and seat 12 begin to separate to form a gap 46 , while at the same time the backrest 14 tilts backward and the seat 12 travels forward and tilts upward as shown . in fig6 , the backrest 14 and seat 12 have reached their maximum range of travel and the user &# 39 ; s buttocks 41 are located in the gap 46 . in fig5 and 6 , the user 44 is cradled in a tilted orientation in the chair , so that the user &# 39 ; s weight is born in the chair cradle . when the gap 46 is widened , the user &# 39 ; s sacral region and hips sink partially into the gap . this creates a gravitational traction on the spine which helps the spine &# 39 ; s initial relaxation to occur . also , relaxation of the shoulders 45 is aided by gaps 42 in backrest 14 which allow the shoulders 45 to fall by gravity , especially in the orientation shown in fig6 . when shoulders 45 fall into gaps 42 , the chest opens up and causes further relaxation . as the gap 46 is opened wider , the mechanical tractive force of the chair 10 further causes the lower body 48 ( located in the seat ) to be pulled in a direction opposite from the upper body 50 ( located against the backrest ). separation is aided by a frictional material 52 covering the body - facing surfaces of both the seat 12 and the backrest 14 . this frictional material 52 grips a user &# 39 ; s clothing as the gap 46 is widened , thus maintaining the user &# 39 ; s lower body 48 in the seat as immobile as possible and further maintaining the user &# 39 ; s upper body 50 as immobile as possible against the backrest 14 . the frictional material 52 operates on a similar principal as neck harnesses , cables , or head retaining appliances often seen used with traction tables ; that is , to maintain body parts as immobile as possible so that as traction is applied , the lower body 48 and upper body 50 are pulled in opposite directions , thus opening up the spine and relieving pressure thereon . the inventor has found that material used on motorcycle seats provides an exemplary frictional material which suffices for the purposes of the invention . fig7 shows the framework and articulating components of the inventive traction chair 10 which underlies the padded seat 12 , backrest 14 and footrest 98 . as shown , a central stationary framework 51 provides a foundation upon which are hung the articulating components of the chair 10 . the articulating components are comprised of all the components which move upon actuating the chair 10 . these include the backrest framework 60 , the seat carriage 62 , front seat carriage support 64 , footrest assembly 66 , connecting rods 68 and electronic telescoping actuator 70 . framework 51 is comprised of a base which includes left and right side foot members 58 which are connected by cross beam 72 and four vertical members , two in front 74 and two in the rear 76 . cross beam 72 includes a mounting plate ( not shown ) for the electronic telescoping actuator 70 which will be discussed in more detail later herein . referring also to fig8 a , left and right armrests 16 are connected to the central stationary framework by vertical members . left and right guide rails 78 connect front and rear vertical members 74 , 76 and guide rails 78 are mounted parallel with left and right armrests 16 . at the uppermost points of left and right front vertical members 74 are mounted rollers 80 which face each other on the inside of vertical members 74 . fig8 a - 8c illustrate the graduated movement of the articulating components as the chair is articulated from a resting position ( fig8 a ), to a middle position ( fig8 b ), to a fully deployed position ( fig8 c ). the articulation is achieved by the movement of actuator 70 coupled with the connection of the articulating components which transfer the force from the actuator 70 throughout the various components . by illustration , the connecting rods 68 connect the backrest framework 60 to the seat carriage support 64 and in turn backrest framework is pivotally connected 79 to rear vertical members 76 . connecting rods 68 have a first end 82 which pivotally connects to the top of the seat carriage support 64 and a corresponding second end 84 which pivotally connects to a bottom end of the backrest framework 60 . connecting rods 68 provide a linkage connecting backrest framework 60 , seat carriage support 64 and seat carriage 62 , thus allowing them to articulate in a simultaneously coordinated fashion . seat carriage 62 travels horizontally forward and back on left and right guide rails 78 ; when traveling in its forward horizontal direction , the seat carriage 62 separates seat 12 from the backrest 14 , thus opening up the gap 46 between the seat and backrest as discussed above . as further shown in fig9 , seat carriage 62 is essentially a framework , laid horizontally , which supports the seat . a pair of rollers 86 is attached to seat carriage 62 in an outboard fashion , which allows them to engage with left and right guide rails 78 , the rollers 86 being spaced to fit over guide rails 78 and travel evenly upon them . a seat carriage support mounting bracket 88 is located in the center of seat carriage 62 . mounting bracket 88 attaches to cross tube 92 of front seat carriage support 64 . left and right side rails 90 of seat carriage 62 extend substantially forward of mounting bracket 88 . fig1 shows the seat carriage 62 mated with the guide rails 78 . when rollers 86 are mated to guide rails 78 , they provide a weight - bearing support for the rear of the seat carriage 62 . the seat carriage support 64 is pivotally connected 63 to foot members 58 which provides a more forward - positioned weight bearing support for the seat carriage 62 ( see fig8 a - 8c ). as shown in fig8 a - 8c , as seat carriage 62 travels upon the left and right guide rails 78 the orientation of seat carriage shifts as the seat carriage travels along the contours imparted into left and right guide rails . guide rails are contoured with an upward angle as they extend to the front of the chair 10 . as the seat carriage travels forward , the upward slope of the guide rails 78 causes the seat 12 to angle upward . this action tends to lift the user &# 39 ; s feet off of the ground causing the user 44 to be cradled by the seat 12 and backrest 14 as shown in fig6 . this suspension of the user &# 39 ; s body off the ground causes the user &# 39 ; s weight to sink into the gap 46 . toward the rear 94 of the chair 10 , guide rails 78 adopt a severe concave bend 96 which , when the seat 12 travels backward , causes rollers 86 to dip into the bend 96 , which causes the seat 12 to angle downward , to a level orientation ( see fig4 ). at this point the user is again sitting upright and his feet are flat on the ground as shown in fig4 and the gap 46 between seat and backrest is nonexistent . the traction chair 10 can then be used as any normal chair in this orientation . the inventive traction chair 10 has a footrest assembly 66 that is deployed when the chair is in its maximum traction orientation as shown in fig6 . the footrest assembly 66 is designed to actuate into a deployed position as the seat carriage moves to its forward positioning . footrest assembly 66 is comprised of a frame 99 attached to a footrest cushion 98 . frame 99 has two rearward - extending side rails 100 joined by cross - member 104 . side rails 100 are pivotally attached to the front of seat carriage 62 at pivotal attachment points 102 . a length of side rails 106 extend rearward of the attachment points 102 . the rearward extension of side rails engages rollers 80 attached near the top of front vertical member 74 . as seat carriage 62 travels forward it forces the rearward extensions 106 against rollers 80 , causing the footrest assembly 66 to rise to a deployed position ( see fig4 - 6 ); when the seat carriage 62 travels in reverse , the footrest assembly 66 falls until it reaches a stowed position . the actuator 70 is preferably comprised of an electric motor 108 attached to a telescoping shaft 110 . in fig4 - 6 , the chair is shown with the telescoping shaft 110 traveling from minimal to maximum deployment . the electric motor 108 attaches to motor mount ( not shown ) on cross beam 72 . the telescoping shaft 110 has a first end which connects at pivotal attachment point 112 to the front seat carriage support 64 . the second end of the shaft 110 connects to the electric motor 108 . the electric motor 108 can be selectively actuated in a forward and reverse direction . the forward direction places force on the front seat carriage support 64 and causes the seat 12 to travel forward in the manner previously described . the remaining articulating components also operate as described herein . when the forward - most extension of telescoping shaft 110 is reached ( see fig6 ), the widest gap 46 between seat 12 and backrest 14 is also achieved ; however a user may actuate the motor to whatever point feels most comfortable and which decompresses the spine . manual methods of actuation are also contemplated in the invention . for example , although not shown in the drawings , a manual actuating handle could be used as a means for supplying motive force ( in place of actuator 70 ) to the articulating components of the traction chair . the handle would be operated by the user &# 39 ; s muscle force , and force could be applied by the user against the front seat carriage support 64 through a linkage attached to the handle . the handle could be engineered to have several “ stops ” so that the user could selectively actuate the chair to achieve different sizings of gap 46 which most comfortably fit the user and decompress the spine . fig1 and 12 propose a second manual means for actuating the chair . in this embodiment , a pair of springs 114 are attached to foot members 58 at their first ends and further attached to seat carriage support 64 at their second ends . the user 44 would seat herself in the chair 10 and push down and forward on arm rests 16 , and lean back against backrest 14 , thus manually causing seat 12 to move forward on guide rails 78 and cause gap 46 to open up . at maximum extension of springs 114 , the maximum gap 46 would be opened . a stop or lockout position could be engineered by means well known in the art when the maximum extension is reached , thereby allowing the user to relax from applying manual force upon armrests 16 . when it is desired to retract the chair , the user 44 would grasp armrests 16 and apply downward force on footrest assembly , thereby overcoming the lockout position and forcing the seat 12 to travel rearward , thereby causing the chair 10 to return to its retracted position as shown in fig1 . stop 116 would prevent any further rearward travel of backrest 14 once the chair 10 returns to its retracted position . finally , although the description above contains much specificity , this should not be construed as limiting the scope of the invention , but as merely providing illustrations of some of the presently preferred embodiments of this invention . this invention may be altered and rearranged in numerous ways by one skilled in the art without departing from the coverage of any patent claims , which are supported by this specification .
