Abstract: A fixed public seating construction includes welded structural steel frame assemblies, each of which includes a standard, a floor mount plate, a seat support or mounting bracket, a back support or mounting bracket, and an arm rest support, all welded together at the manufacturing plant as a single unit. The public seating construction also incorporates relatively rigid plastic shell type seat and back components which will accommodate (on their "back" or non-use sides) optional inserts of wood, laminate, fabric, etc. Both the back and seat components are comprised of unitized, blow molded shells, filled with foam. In addition, both have mounting assemblies which include steel mounting inserts fixed in place during the blow molding operation, as well as associated support bars which are fastened to the inserts in overlying relationship, prior to shipping. Both the back and seat components have "drop-in" mounting features, and a free floating hinge is also provided for mounting the seat to the frame.
