Abstract

An aircraft cabin floor arrangement includes two floor support part-structures, each having vertical support members, a beam member, cantilevering members and a seat rail. The beam member and the seat rail extend in a first direction with the seat rail being carried by the beam member. The cantilevering members cantilever in a second direction transverse to the first direction. The vertical support members extend in a third direction transverse to the first and second directions. The two floor support part-structures are each configured to be arranged along opposing side portions within an aircraft fuselage structure and are configured to transfer load from the cantilevering members and the beam member to the fuselage structure. The cantilevering members and the beam member are configured to carry a cabin floor configured to provide a load transfer in a plane direction of the floor and to contribute to a stiffening of the fuselage structure.
