Aircraft Seat Flap Element Gap Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft seat designs lack adequate safety features to prevent passenger injury during crashes, particularly from the hooking between the backrest and backrest bridge, and require improved storage solutions for personal items.
Innovation Solution
An aircraft seat device with a pivotally arranged flap element that covers the backrest area above the backrest bridge in a closed state, forming a storage container and bridging the gap between the backrest and backrest bridge to prevent injury, made from a material with an elastic modulus of 1500 MPa to 3000 MPa, and equipped with a locking mechanism for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a backrest bridge is introduced to connect lateral boundaries of the backrest, then structural stability is improved, but it creates a harmful gap that can cause passenger injury during crashes
Solution Approach 1:
A flap element is introduced as an intermediary component between the backrest bridge and the backrest. This flap element pivotably connects to the backrest bridge and can rotate to cover the harmful gap, preventing passenger injury during crashes while maintaining the structural stability provided by the backrest bridge.
Solution Approach 2:
The flap element is designed with rotational freedom around a pivot axis, allowing it to dynamically adjust its position. In normal conditions, the flap element covers the gap for safety; during a crash, it can rotate to absorb impact forces, transforming the rigid structure into a dynamic safety feature.
2Reliability
If the flap element is made from elastic material with modulus 1500-3000 MPa, then crash energy absorption is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a particular range for the elastic modulus (1500-3000 MPa) to optimize the balance between structural integrity and energy absorption. This parameter control allows the flap element to deform elastically during crashes, absorbing impact energy while returning to its original position, thus improving reliability without requiring extreme manufacturing precision.
3Object-affected harmful factors
If the flap element pivotably connects to the backrest bridge, then safety during crashes is improved, but device complexity increases
Solution Approach 1:
The backrest assembly is segmented into distinct functional components: the backrest bridge for structural support, the flap element for safety coverage, and the pivot mechanism for dynamic adjustment. This segmentation allows each component to be optimized independently while working together to prevent passenger injury without excessive overall complexity.

AI summary
The invention is based on an aircraft seat device with at least one backrest (10a; 10b), with at least one backrest bridge (16a; 16b), which at least substantially spans the backrest (10a; 10b) at least in a transverse direction, and with at least one flap element (14a; 14b) which is arranged so as to be pivotable in the region of the backrest bridge (16a; 16b). It is proposed that the at least one flap element (14a; 14b), at least in a closed state, covers at least one backrest region (46a; 46b) above the backrest bridge (16a; 16b).
