Aircraft Seat Adapter Plate for Accessory Mounting and Sound Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cabins with aft tapered sections require narrow-width triple seats to avoid interfering with aisles, which is undesirable for passengers, and mounted auxiliary accessories like bassinets can disrupt the environment by allowing sound to carry through between dividers, potentially interfering with forward classes.
Innovation Solution
An adapter plate for aircraft seats that includes a body with couplers to attach to the seat and mount points for auxiliary accessories, allowing these accessories to be positioned near the seat without interfering with aisle width or sound transmission, and can be integrated with the seat or deployed from it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If narrow triple seats are used in the aft tapered section, then the aisle interference is avoided, but the passenger comfort deteriorates
Solution Approach 1:
The patent extends the seat structure laterally into the aisle space by adding armrests and auxiliary accessory mounting capabilities that protrude beyond the traditional seat boundaries. This dimensional extension allows the seat to maintain standard width while utilizing the three-dimensional space more efficiently, avoiding aisle interference while preserving passenger comfort.
Solution Approach 2:
The auxiliary accessories (bassinets, storage bins, etc.) are nested within or attached to the seat structure itself, utilizing the space envelope created by the seat's armrests and body. This nesting approach allows additional functionality without requiring separate mounting space that would encroach on the aisle.
2Ease of manufacture
If bassinets are mounted on the bulkhead or divider, then the installation location is convenient, but sound transmission increases
Solution Approach 1:
The bassinet mounting function is extracted from the bulkhead/divider structure and relocated to the seat structure itself. By taking the accessory mounting capability out of the partition wall and integrating it into the seat, the invention eliminates the sound transmission pathway through the bulkhead while maintaining convenient installation and accessibility.
Solution Approach 2:
The seat structure acts as an intermediary between the passenger and the auxiliary accessory (bassinet). Instead of directly mounting the bassinet to the bulkhead, the seat serves as the intermediate mounting platform, providing acoustic isolation while maintaining the functional relationship between the passenger and the accessory.
3Object-affected harmful factors
If auxiliary accessories are mounted on the seat, then the sound interference is reduced, but the space utilization is limited
Solution Approach 1:
The armrests and auxiliary accessory mountings are designed to be deployable and configurable rather than fixed. The armrests can be extended or repositioned to create the necessary space envelope for auxiliary accessories, dynamically adapting the space utilization based on the specific accessory requirements while maintaining acoustic isolation.

AI summary
An adapter plate for an aircraft seat may include a body configured to be positioned exterior of an armrest of the aircraft seat within a space proximate to the aircraft seat. The body may include at least one coupler configured to attach to the aircraft seat. The body may include at least one mount point. The at least one mount point of the body may be configured to attach to at least one mount bracket of the removable auxiliary aircraft accessory. The auxiliary aircraft accessory may be positioned within the space proximate to the aircraft seat when coupled to the at least one mount point of the body via the at least one mount bracket.
