ABSTRACT:
A plastic back support plate, formed of a firm but bendable material is connected to two side plates by curved integral hinges along opposite edges of the support plate that engages the back of the user. When deflected, these side plates cause the back support plate to be curved to a degree depending upon the angular deflection of the two side plates. The side plates are secured in the desired position by an adjustable strap extending between the outer edges of the side plates.
To enhance portability, the back support mechanism is formed of a plurality of linear parallel segments that are connected together by linear integral hinges. These straight hinges are spaced and extend from edge to edge across the entire back support mechanism. When the side plates are undeflected, that is, lie in the plane of the support plate, the mechanism can be folded into a roll, about an axis parallel with the straight hinges, and that roll is comparable in size to a small folding umbrella.
