Abstract
An assembly unit for the interior finishing of passenger carrying vehicles, in particular of two story railroad car type, consists of modular prefabricated functional units each having at least one of the functions cable duct, loudspeaker, illumination, baggage repository, window shade, and interior covering. Support beams of the functional units are suitably designed aluminum extrusions. The prefabrication of the functional modules takes place outside of the car body in a workshop region specially equipped for this purpose and comprises the working procedures, mechanical processing, surface treatment, assembly of the functional devices, prewiring and functional testing. The functional modules are installed and assembled in a predetermined sequence in the car body into an assembly unit containing the named functions. The attachment of the functional modules is in part by means of bolted connections on the C-shaped rails mounted in the car body and in part by means of tongue-and-groove connections formed on the extrusions. Depending on the function and the configuration of the car body, the functional units can have different lengths and abutting unit are attached by dowel pins for step-free transitions.
