Corresponding to reducing the number of components that need to be separately installed, in addition to a weight reduction and a reduction in the cable loom volume, improved system reliability is obtained if the loads relating to a seating space in a passenger cabin (12), in particular in an aircraft, are combined on an overhead panel (17) which is connected, via line connections which are now only short, to a spatially associated supply module (19), which is operated in cutouts (20) in a stub frame (13), in order to anchor a hat rack (11) in the fuselage structure (16) of the cabin (12).
