An arm cap friction hinge mechanism may include a center link; a first top link, a top friction hinge link, a second top link, and a top pin link coupled to the center link; an upper hinge mount coupled to an arm cap, to the first top link, and to the top friction hinge link via a first friction hinge; an upper pin mount coupled to the arm cap of the aircraft seat, to the second top link, and to the top pin link. The center link may be coupled to at least one hinge mount via at least a second friction hinge. The arm cap may be configured to actuate between a closed position and a first open position around the first friction hinge, and between the first open position and a second open position about an axis through the at least a second friction hinge.
