A cargo rack is provided which is intended to supported on a support structure, such as the roof of a vehicle, and to be retractable to facilitate loading and unloading of the rack. The retractable cargo rack assembly includes a base frame adapted to be securely mounted to the support structure and a cargo rack that is supported by the base frame but which is movable between a retracted position, in which the cargo rack is positioned juxtaposed to the base frame, and an extended position for loading/unloading. To facilitate shifting of the cargo rack, a power drive mechanism is provided to automatically position the cargo rack in either of its retracted or extended positions upon actuation of the power drive mechanism. Once in the extended position, one or more platforms attached to the cargo rack can be shifted relative to the cargo rack. Once shifted, the platforms are substantially located in respective horizontal planes. While in this position, luggage or other cargo can be readily loaded upon or unloaded from the platforms, Once the loading/unloading operation is complete, the power drive mechanism can be activated to automatically retract the cargo rack.
