Abstract
A hinge is provided for adjustable, hospital-type beds of the type having at least one articulated mattress support section. The hinge comprises two hinge plates, each having three pivot points thereon arranged in a triangular pattern. The upper ends of the hinge plates are attached to the bed frame and movable bed section respectively. The adjacent, lower pivot points of the two plates are rotatably interconnected, and the remaining pivot points are rotatably attached to a pair of links. The upper ends of the links connect their respective plate to that bed section opposite to the bed section the upper hinge plate end is attached to, whereby the movable bed section rotates about an imaginary axis above the mattress support to alleviate compression of that portion of the mattress positioned between the two bed sections when the movable bed section is raised.
