All prior art references can be grouped into three categories.
The first, the most commonly used, today, in airplanes, trains and long dlstance buses, is seat with the back plate inclining backward and pivot~ng at its lower end, with the bottom plate fixed in posit~on at all times. The second is seats with the back plate not pivoting at their lower end and the bottom plate moving forward while the back plates are pivoting. The others are not commonly used, such as seats with a back plate moving downward and a bottom plate moving forward, seats with a fixed angle between back plate and bottom plate, seats with tilting, swiveling or osc;llat;ng movements.
None of the prior art references show an apparatus for the purposes of increasing usable space in horizontal and vertical directions, straightening a human body in a comfortable and relaxing environment, nor achieving a significant economic value.
Accordingly, there remains a need for an invention to maximizP
usable space thereby achiev1ng a comfortable and relaxing environment and a significant economic value for travelers and audiences.

~S~5:2 Summary of the invention The present invention is an economical, comfortable, relaxing and cost effective body contour support structure for travelers and aud~ences.
It can be equipped onto~ but not be limited to, air, land and water Yehicles, such as airplanes, buses, cars, trains and ships; and places, such as theaters, convention halls, and public and private premises.
The seat comprises a base, a bottom plate and a back plate. The bottom and back plates are slid~ng and rotating from sitting to incllning positions. These movements are const~tuted by a number of means of rotating and sliding which are interconnected to the base, bottom and back plates of the body contour support strurture.
The angle between the bottom plate and the back plate increases substantially from 9~ degrees to 180 degrees to straighten a human body, thereby maximizing the useable spaces 1n horizontal and vert~cal directions to provide a comfortable and relaxing environment, constitut~ng a first difference from all prior art references.
The following are also the differences between the present invetion and all pr~or art references.
~ he-second difference is the upward and rotating movement of the back plate to ex~end and increase the horizontal and vertical spaces when the back plate is in lncline position.
The third difference is the downward movement of the front end of the bottom plate. It is able to extend and increase the leg room to straighten the legs of an occupant.
The fourth difference is the upward movement of the rear part of the bottom plate. This movement increases the vertical space under this bottom plate while the back plate is ~n incllne position.
The fifth difference is the guided upward or downward movement oF
the front end of the bottom plate in a sultable position to accommodate the leg room of an occupant.
~3~356~2 The s~xth difference is the configurations and compositions of the bottom plate and the back plate which maximize the useable spaces and provide adequate comfort.
The invention will be better understood by reading the following terms, descriptions and figures showing the configurations and the compositions of the elements of the invention.
Terms and elements of the invention Seat: Seat is a structure which is supporting a human body in space.
Space: Space is an unobstructed place whlch can be occupied by ojects.
