ERGONOMICAL POSTURAL BALANCING AND SUPPORTING DEVICE FOR THE HUMAN BODY, PARTICULARLY VARIABLE ISCHIO-LUMBAR ADJUSTMENT SEATS

摘要

An ergonomic postural balance and dynamic support elements or the body segments movable supports mechanically synchronized, in particular a seat in the ischio-lumbar variable pitch. The weight of an element or body segment controls movement of the support (1) (seated), pivoting around a fixed axis (2) or sliding on rails which leads mechanically, via a flexible transmission (5) sliding on a roller (6), the rocker lever support (3) (folder) around the fixed axis (4), supporting posture corrected in the body segment to bear against the latter carrier. It achieves a balanced and harmonious support of one or more body segments regardless of the position changed at will and at any time.
