  • Patent number: 6598829
    Abstract: Hand luggage locker assembly for use in an aircraft cabin. The assembly includes a shell-like locker, a track mechanism for moveably connecting the locker to an aircraft structure between a closed position and an open position, and a lifting mechanism for relieving the muscle power required for a user to move the locker between the closed position and the open position. The lifting mechanism includes a moveable lifting body which, on one side, is connected to the track mechanism or to the locker and, on its other side, is connected to the aircraft structure, which lifting body is coupled to a pneumatic system. The pneumatic system includes means for supplying an underpressure compared to the pressure in the cabin, control means being provided for at least supplying the underpressure to the lifting body when the locker is to be moved upwards in a controlled manner with the aid of the underpressure as power source.
