SEAT ASSEMBLY FOR MASS TRANSIT VEHICLE

摘要

A mass transit seat assembly of modular construction. The seat assembly includes a universal seat frame which is formed of roll formed steel members and which is usable in combination with a variety of support bracketry so that a single common seat frame may be utilized to provide a variety of seating positions and seating attitudes within the vehicle. The seat frame includes side rails and cross rails extending between the side rails. Fastener assemblies mounted on the associated bracket hardware include nuts slidably positioned within the respective cross rails and bolts extending upwardly through the bracket for threaded engagement with to the nuts. The invention provides an improved cantilever support assembly by virtue of which a single cantilever construction may be utilized to satisfy a wide variety of seating requirements; an improved wall mount bracket arrangement wherein the wall mount bracket is releasably secured to the cross rails utilizing fastener assemblies; an improved and simplified means of mounting the seat shell to the seat frame; and an improved seat frame in which all of the cross rails are identical and therefor interchangeable.
