A folding seat hinge (10) having a first hinge member (16) with an arcuate slot (46) radially displaced from the pivot axis (40) of the hinge. A second hinge member (12) is disposed with respect to one side (54) of the first member (16) to fully cover the slot (46) over the full range of pivoting motion of the hinge members (12, 16). A guide pin (58) is coupled to the second member (12), extends through the arcuate slot (46) in the first member (16) and functions to limit the pivoting motion between the hinge members. A cover plate (70) is disposed with respect to an opposite side (72) of the first hinge member (16) to fully cover the slot (46) over the full range of pivoting motion. A pivot pin (14) secures the hinge members (12, 16) and the cover plate (70) in an assembly and provides the axis of rotation (40) for the hinge members.

[ What is claimed is:] [1.] A chair hinge for connecting a folding seat back to a seat bottom, the folding seat back being movable between generally upright and folded positions with respect to the seat bottom, the chair hinge comprising:a first member having a mounting surface connected to one of the seat back and the seat bottom, the first member having an arcuate slot;a second member having a mounting surface connected to the other of the seat back and the seat bottom and being disposed with respect to the first member such that over a full range of relative motion between the first and second members, the second member fully covers an area of the slot on an inner side of the first member;a cover plate disposed adjacent an outer side of the first member, the cover plate being sized to fully cover the area of the slot on the outer side of the first member over the full range of relative motion between the first and second members;a guide pin mechanically engaging the second member and the cover plate and extending through the slot in the first member, the slot in the first member having ends for stopping relative motion between the guide pin and the slot to define limits of the full range of relative pivoting motion between the first and second members; anda pivot pin providing relative pivoting motion between the first and second members and securing the first and second members and the cover plate in a hinge assembly that, over the full range of motion, does not have pinch points.
