Flight Attendant Seat Frame Layout for Compact Cabin Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flight attendant seats are not compact or lightweight, and their installation methods are complex, making them difficult to fit in the limited space of an aircraft cabin.
Innovation Solution
A flight attendant seat with a frame that can be mounted on a carrier fixture, featuring a lower section, an upper section, and a central section with bent regions for optimal load distribution, allowing for a compact and lightweight design with integrated seat arrangements and accessories, and a method for easy installation involving frame elements that can be connected and rotated for simplified fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional flight attendant seats are used, then the seat provides adequate support and functionality, but the seat is not compact or lightweight and occupies excessive space
Solution Approach 1:
The seat element is designed to be nestable within the backrest when folded, with the seat element containing a recess that receives the folded seat element. This nesting arrangement minimizes the volume occupied by the seat while maintaining structural integrity and support functionality.
Solution Approach 2:
The seat element is designed with folding capability to transition between extended and retracted positions. This dynamic design allows the seat to adapt its volume based on operational requirements, providing full support when needed and compact storage when not in use.
2Weight of moving object
If traditional flight attendant seats are used, then the seat provides adequate support, but the seat is heavy and increases overall weight
Solution Approach 1:
The seat is divided into separate modular components including the backrest, seat element, and frame structure. This segmentation allows for optimized material selection and construction methods for each component, reducing overall weight while maintaining structural support through strategic placement of high-strength materials.
Solution Approach 2:
The frame and structural components utilize composite materials that provide high strength-to-weight ratio. This allows the seat to maintain adequate support functionality while significantly reducing overall weight compared to traditional solid metal constructions.
3Ease of manufacture
If traditional installation methods are used, then the seat can be installed, but the installation process is complex and difficult to fit in limited space
Solution Approach 1:
The seat assembly is divided into modular components (backrest, seat element, frame sections) that can be independently manufactured and then easily assembled. This segmentation simplifies the installation process by allowing components to be installed separately in the limited space of an aircraft cabin rather than requiring installation of a complete complex assembly.
Solution Approach 2:
The frame design incorporates universal mounting features that can accommodate different installation configurations and carrier fixtures. This multi-functionality allows the same seat design to be installed in various locations within the aircraft cabin using standardized procedures, reducing installation complexity.

AI summary
A flight attendant seat comprising a frame that can be mounted on a carrier fixture or integrated into the carrier fixture, and at least one seat arrangement integrated into the frame. The frame comprises a lower section, an upper section and a central section taking up the at least one seat arrangement, at least partially. The lower section is formed bent at least in a region adjoining the central section. A method is provided for fitting a flight attendant seat.
