Abstract

This auditorium seat has a frame preferably formed of bent steel tubing, the ends being brought together to parallelism in a 'Y'-shaped configuration to form a pedestal. A seat is pivotally mounted on a spring hinge assembly between the sides of the frame, and includes a transverse saddle platform to which a 'U'-shaped rod extends forward from end-receptacles on the platform. Seat-supporting straps are welded to the central portion of the 'U'-shaped member to form a complex bending-torsion deflection system in addition to the cushioning effect of a pad interposed between the plates and the saddle. The back of the chair has limited freedom of articulation about horizontal and vertical axis, with a spring cushion providing a biasing action toward a neutral no-load position. A modified form of the invention provides a tablet arm assembly supported by a bracket embracing one side of the frame at a curved portion.
