Weightless chair, seat pan and backrest

Abstract

The weightless chair, seat pan and backrest is designed to address an area of the body which has almost become a nemesis in the health/fitness and exercise fields. This area often referred to as the core musculature is the site of the central mass of the human body. It is of particular importance because it too is the location of our pelvic, lumbar and abdominal anatomy. The weightless chair seat pan and backrest are so designed to give infinite range of the motion to the structures of this area. It creates a weightless and friction less movement system, which follows clearly delineated pathways. Said device has the capacity to introduce friction as needed and to integrate both linear pathways, such that intellectual collinear and angular movement patterns can be accomplished. Experts in the field of fitness and exercise are all too aware of the need for pelvic strength and pelvic mobility. As the torso or trunk area of the body interacts with the weightless chair, seatpan in backrest in a sophisticated movement system, the resulting outcome of which is that the body's core area will move with the exactness of a gyroscope, the results of which will have dimensional proportions. The machine that runs without friction is destined to last the longest.

1 ) A collinear moving seatpan and backrest, to provide for both passive and active exercises, while seated. Comprised of a linear and collinear, multilayered, planar moving structure, being capable of free, as well as restricted and limited movement in both the x and y directions, following both the frontal and coronal planes of the human body.  
   
   
       2 ) Collinear moving seatpan and backrest as in  claim 1 , consisting of a multilayered, articulating planar structure for the back, and a multilayered, articulating planar structure for the buttocks.  
   
   
       3 ) Collinear seatpan and backrest, as described in  claim 1 , maybe fixedly attached or “built into” conventional chairs or seating with both structures installed as one unit together or may be installed as individual components separately.  
   
   
       4 ) It is anticipated that said multilayered collinear seat plan and backrest as described in claim one, can too be built as a portable unit, designed such that both can be installed as individual components or as one combined component. And may be removably attached at will to existing conventional chairs and seating.  
   
   
       5 ) Seatpan and backrest as described in  claim 1  consisting of a base platform, either fixedly attached or removably attached to an existing seatpan or a backrest containing sets of balls or rollers arranged in a parallel manner, so as integrate with the next most distal platform.  
   
   
       6 ) Seatpan and backrest, as in  claim 1 , having a second planar structure, one for the seatpan and one for the backrest having on one side troughs or passageways, which a line with the existing sets of parallel balls or rollers of the previous base structure. And on the front surface of said second planar structure another set of rollers or balls, which are arranged parellelal and at a right angle to the previous rollers or balls on the base planar structure. Such is the case for the backrest as well as for the seatpan.  
   
   
       7 ) Seatpan and back rest as in  claim 1 , having a third articulating planar structure, which has troughs to integrate with the second planar structure. Giving both said seatpan and backrest horizontally in a direction perpendicular to the base set of parallel rollers.  
   
   
       8 ) Articulating platforms as described above are held loosely into place via passageways and aligning pins. Said aligning pins, are designed such that, a coefficient of friction may be introduced onto the rollers by compressing said aligning pins via tightening, to increase one's exercise potential.  
   
   
       9 ) Articulating backrest as described in  claim 1 , designed such that it can be installed and on its original base structure with the secondary platform, allowing for core linear directional movement or otherwise said secondary platform, they be installed directly to the seat back and allowing for just linear movement giving side to side direction only.  
   
   
       10 ) Each reciprocal platform is so equipped with stop limiting devises, so as to limit distance that can be traveled in each direction.  
   
   
       11 ) Seatpan as specified in  claim 1 , attached to a third planar structure. The seatpan itself is capable of rotational movement via one central access via a lazy-Susan type structure.
