Aircraft Passenger Seat Side Body Pivot for Lateral Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passenger seats in transportation vehicles, particularly airplanes, pose a barrier for individuals with restricted mobility due to the base body obstructing direct access to the seat surface, hindering easy access and comfort.
Innovation Solution
A passenger seat device with a bearing unit that allows the base body to be moved laterally or pivoted into a release position, enabling easy access by allowing the base body to be adjusted away from the seat surface, incorporating a pivoting device with multiple axes for ergonomic design and a locking mechanism for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base body laterally covers the seat surface in the position of use to provide structural support and stability, then the structural stability is improved, but the ease of operation deteriorates due to blocked lateral access for passengers with restricted mobility
Solution Approach 1:
The base body is designed to be movable rather than fixed, allowing it to transition between a position of use (providing lateral coverage and stability) and a release position (allowing lateral access). The bearing unit enables this dynamic reconfiguration, resolving the contradiction between structural stability and ease of operation for passengers with restricted mobility.
Solution Approach 2:
The base body is divided into movable and stationary portions, with the movable portion capable of being adjusted relative to the seat surface. This segmentation allows the lateral covering function to be separated from the fixed structural support, enabling the base body to provide stability when needed while allowing access when required.
2Ease of operation
If the base body is made movable to improve accessibility for passengers with restricted mobility, then the ease of operation is improved, but the device complexity increases due to the bearing unit and pivoting mechanism
Solution Approach 1:
The base body is designed to be movable by the passenger themselves through the bearing unit, without requiring external assistance or complex control systems. The pivoting mechanism allows the passenger to independently adjust the base body position, improving accessibility while avoiding the need for additional complex actuation systems.
Solution Approach 2:
The base body position is changed by varying the degree of pivoting around the pivot axis, allowing continuous adjustment between the position of use and the release position. This parameter-based control simplifies the mechanism compared to discrete positioning systems, reducing overall device complexity while maintaining ease of operation.
3Adaptability or versatility
If the base body is designed with a pivoting mechanism to enable movement into release position, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The base body serves multiple functions: it provides lateral coverage for structural stability, acts as a support element, and can be pivoted to enable accessibility. This multi-functionality is achieved through a single integrated design rather than multiple separate components, reducing manufacturing complexity while maintaining adaptability.
Solution Approach 2:
The base body is designed to pivot around a horizontal axis, adding a rotational degree of freedom to the otherwise fixed structure. This dimensional change allows the base body to move between positions without requiring complex linear actuators or multiple connection points, simplifying manufacturing while enabling position adjustment capability.

AI summary
An airplane passenger seat device includes a seat part, which has a seat surface, a seat direction and a main body, which abuts an aisle in a installed state in a means of transportation and which, in a usage position, laterally covers the seat surface in a region that is lateral to the seat surface with respect to the seat direction. It is proposed that the passenger seat device has a bearing unit for moveably mounting the main body, which is provided to move the main body from the usage position into a release position by way of a movement relative to the seat surface, which causes the region lateral to the seat surface to be released.
