Abstract

The invention relates to a center of gravity control display system for measuring the human body and/or prosthetic or orthotic fittings in their positions relative to the human body. According to the invention, this system consists of a measuring plate (1) for determining center of gravity (4) projected in the plane of measuring plate (1), of a person standing on measuring plate (1), and of a projection device (2) for projecting a perpendicular measuring line onto the body of said person, with measuring plate (1) being provided with pressure sensors (3) connected with one another by a circuit, said sensors delivering an electrical signal defining the determined center of gravity position, said signal controlling a drive that displaces an optical system in a plane parallel to that of measuring plate (1), said system projecting a light beam (19) as a vertical measuring line that defines a plane in which center of gravity (4) of the person being measured lies.
