摘要

A stairway module for use within a fuselage of an aircraft for enabling access to an overhead storage or sleeping area within the aircraft. One preferred embodiment discloses a spiral stairway module having a footprint no larger than a standard lavatory module. Another embodiment includes a stairway module having a pivotally mounted stair section which can be moved between operable and inoperable positions. Both embodiments provide a mid-level platform changing area. All of the embodiments are extremely compact and allow either fore-to-aft access or athwartship access to the overhead sleeping or storage area in the fuselage of the aircraft.
