Passenger Aircraft Cabin Bed Supported by Folding Flight Attendant Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabin designs in passenger aircraft do not efficiently utilize space for crew rest facilities without occupying passenger seating, and additional supports for beds are often required, which can disrupt passenger access and increase costs.
Innovation Solution
A cabin section with a folding flight attendant seat and bed that can be adjusted between use and stowed states, where the bed is supported on the seat, allowing the seat to serve dual functions and eliminating the need for additional supports, with a floor section available for passage when both are stowed and covered when in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional supports are installed for the bed, then the bed can be supported, but the passenger access is disrupted and costs increase
Solution Approach 1:
The invention combines the bed support function with the existing flight attendant seat structure. The bed is supported by the seat base and backrest when the seat is in the stowed position, eliminating the need for separate support structures. This merging approach provides reliable bed support while maintaining clear passenger access paths.
Solution Approach 2:
The flight attendant seat serves multiple functions: it provides seating for flight attendants during operations, serves as a support structure for the bed during crew rest, and helps define the floor section boundaries. This multi-functionality eliminates the need for dedicated support elements that would obstruct passenger movement.
2Device complexity
If the flight attendant seat is used to support the bed, then additional supports are eliminated and costs are saved, but the seat must serve dual functions
Solution Approach 1:
The seat is designed to perform both its original function of providing seating for flight attendants and the new function of supporting the bed. The seat base and backrest structure are utilized to support the bed when the seat is in the stowed position, eliminating complex additional support structures while accepting multi-functional use of the seat.
3Adaptability or versatility
If the floor section is covered by the seat and bed in use state, then crew rest facilities are provided, but passenger access is blocked
Solution Approach 1:
The floor section coverage is dynamic rather than static. When the seat and bed are in the stowed position, the floor section is exposed for passenger access. When the seat is in use or the bed is deployed for crew rest, the floor section is covered. This dynamic configuration allows the same space to serve different functions at different times without permanently blocking passenger access.

AI summary
A cabin section of a passenger cabin of a passenger aircraft includes a flight attendant seat movable between a state of use and a stowed state, a bed movable between a state of use and a stowed state, and a floor section of a floor of the passenger cabin. The floor section is located between the flight attendant seat and the bed and is available for being walked on, when the flight attendant seat and the bed are both in the stowed state. The floor section is partially covered by the flight attendant seat in the state of use, is at least partially covered by the bed in the state of use, and is completely covered by both when the bed is in the state of use. The bed is supported against the flight attendant seat in the state of use.
