Abstract
A tube joint and seat frame formed with tubes joined with the tube joint of the present invention in which the joint is formed by flaring the end of an outer tube, inserting an inner tube into the outer tube beyond the flare forming a telescoping tube portion in which the outer tube overlaps the inner tube. The clearance formed between the inner and outer tubes by the flare is filled with an epoxy resin adhesive. A metal forming process is performed forming apertures through the inner and outer tubes in the telescoping tube portion in which the aperture in the outer tube is concentric with the aperture in the inner tube and is surrounded by a flange extending radially relative to the axis of the tube into the aperture in the inner tube forming a mechanical interlock between the inner and outer tubes.
