Elongate passenger service unit (PSU) assemblies are comprised of a plurality of modular passenger service units, and a plurality of variable-length modular spacer units. The modular spacer units are positioned between the modular passenger service units in an end-to-end manner so as to provide a desired lengthwise array of the passenger service units along the PSU assembly. Transport category vehicles, e.g., aircraft, may thus be provided with inboard and outboard PSU assemblies. The passenger seats may be arranged in a latitudinally side-by-side arrangement and/or may be arranged in a longitudinally staggered arrangement. By providing variable length modular spacer units, therefore, the individual passenger service units may be arranged directly overhead of each passenger seat. |
