Deployable Seatback Pockets for Aircraft Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seatback pockets in passenger seats, such as those found in aircraft, are fixed and pose challenges for cleaning and storage, as they do not allow access to the bottom of the pocket.
Innovation Solution
The implementation of deployable seatback pockets with a dual pocket design, where each pocket can be opened for access and cleaning, and are positioned to avoid interference with other amenities like video monitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed retention bar is used to define the pocket entrance, then the pocket structure is simple and stable, but the bottom of the pocket is inaccessible for cleaning
Solution Approach 1:
The retention bar is transformed from a fixed structure to a deployable one that can move between a closed position (defining the pocket entrance) and an open position (allowing cleaning access to the pocket bottom). This dynamic mechanism resolves the contradiction by providing both structural stability during use and cleaning accessibility when needed.
Solution Approach 2:
The pocket structure is divided into separate components: the pocket body, the retention bar, and the deployable mechanism. This segmentation allows the retention bar to be independently controlled to move between closed and open positions, enabling cleaning access without compromising the overall pocket structure.
2Quantity of substance
If a single pocket is provided below the video monitor, then the structure is simple, but additional storage space is limited
Solution Approach 1:
The single pocket is divided into two separate pockets (first and second pockets) that can be independently accessed. This segmentation increases storage capacity while maintaining manageable structural complexity through the use of shared components like the common retention bar.
Solution Approach 2:
The deployable retention bar serves multiple functions: it defines the entrance for both pockets when closed, and provides access to both pockets when opened. This multi-functionality increases storage capacity without proportionally increasing structural complexity.
3Area of stationary object
If the pocket is positioned close to the video monitor, then space is efficiently utilized, but the pocket may interfere with video monitor placement or operation
Solution Approach 1:
The deployable retention bar provides a dynamic solution that allows the pocket to be positioned close to the video monitor for efficient space utilization, while the ability to open the retention bar ensures that video monitor placement and operation are not compromised by providing cleaning and access pathways.

AI summary
A passenger seat (102, 104) and a row of passenger seats (100) of a type wherein each seat includes a seatback (110) for locating amenities for use by an aft-seated passenger. The seatback includes a video monitor (120) positioned in an upper portion of the seatback, a first seatback pocket (122) positioned below the video monitor, and a second seatback pocket (126) positioned below the first seatback pocket. Each of the first and second seatback pockets includes a member configured to move apart from the seatback to facilitate access to a bottom of the respective seatback pocket. In embodiments, the first and second seatback pockets are positioned in respective first and second recesses formed in the seatback.
