The present invention is a hinge system for attaching a hinged element to a base forming a hinged unit. The hinge system includes first and second torsion rods fixed to the hinged element and to the base proximate such that the first and second torsion rods are deflected as the hinged element is rotated relative to the base producing first and second torsion forces. The first and second torsion forces prevent the hinged element from twisting as the hinged element is rotated relative to the base. A friction element is connected between the base and the hinged element for offering resistance to the relative rotation of the base and the hinged element.

[ What is claimed:] [1.] A hinge system for hingedly attaching a hinged element to a base, the hinged element and the base together forming a hinged unit, the hinge system comprising:a first torsion rod having a first end fixedly positioned relative to the hinged element proximate a first location on the unit, and a second end fixedly positioned relative to the base proximate a second location on the unit, the first torsion rod configured to be deflected as the hinged element is rotated relative to the base producing a first torsion force;a second torsion rod having a first end fixedly positioned relative to the base proximate the first location on the unit, and a second end fixedly positioned relative to the hinged element proximate the second location on the unit, the second torsion rod configured to be deflected as the hinged element is rotated relative to the base producing a second torsion force;the first torsion rod and the second torsion rod being configured such that the first and second torsion forces prevent the hinged element from twisting as the hinged element is rotated relative to the base; andfriction means connected between the base and the hinged element for offering resistance to the relative rotation of the base and the hinged element.
