Abstract
Abstract A bus seat comprising a metal frame, a bus seat back and a bus seat; said bus seat back includes a front modular portion; a rear modular portion; and a collar portion; said front modular portion affixed to said metal frame; said rear modular portion affixed to said front modular portion; and said collar portion affixed to said front modular portion adjacent said front and rear modular portions. The bus seat is affixed to the metal frame. The modular construction of the bus seat back enables replacement of a specific section or sections of the bus seat. The bus seat back and bus seat can be used in retrofit installations or in new installations. The bus seat back and bus seat are constructed of an elastomer skinned urethane foam which adheres to front, rear and bottom pieces of plywood. The collar portion is constructed of the elastomer skinned urethane foam but does not include a plywood portion. The collar portion is affixed to the front plywood portion.
