ABSTRACT:
A body contour support structure is supporting a human body in space. A bottom plate and a back plate are interhinged and supported by a base. The bottom and back plates rotating and sliding simultaneously in the guided directions are constituted by the orientations of the guides and pins, and a moveable pivot moves in an angled guide to maximize useable spaces in horizontal and vertical directions. The angle between the bottom and back plates is functioning from 90 degrees to 180 degrees providing a most comfortable reading, relaxing or sleeping environment within one seat's spacing. The present invention maximizes the useable spaces and achieves a significant economic value without compromising any space or comfort of the travelers or audiences. As a result of maximizing the useable spaces by ten (10) percent, a ten (10) percent additional gross income will go to the provider's profit or this profit will be shared between the travelers or audiences and provider. This body contour support structure can be equipped onto land, air and water vehicles, and in public and private premises. This particular invention is a real contribution to our daily living and a significant economic value to our many advancing industries.
