Upper Seatback Closeout Assembly With Hidden Tensioned Gap Hider
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating assemblies lack an aesthetically pleasing and functional upper back support that seamlessly integrates with the rest of the seat, failing to provide consistent comfort and adjustability.
Innovation Solution
A decorative closeout assembly featuring a U-shaped body portion made from fabric with peripheral tabs and inwardly-extending flaps coupled with a flexible tensioner, along with hooked barbs that engage with an upper back support's U-shaped peripheral channel, creating a gap hider that maintains the assembly's tautness and adjustability while concealing internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional upper back support design is used, then the structural integrity is maintained, but the aesthetic appearance and seamless integration with the seat is compromised
Solution Approach 1:
The patent uses a flexible fabric cover that conforms to the upper back support structure, creating a seamless aesthetic appearance while maintaining structural integrity through the underlying rigid frame. The fabric acts as a flexible shell that hides the structural components while preserving their strength.
Solution Approach 2:
The patent employs a nested structure where the fabric cover is fitted over the upper back support frame, with internal components nested within the frame structure. This nesting allows the aesthetic cover to envelop the functional structure without compromising either appearance or strength.
2Ease of manufacture
If visible fasteners are used to attach the upper back support, then the ease of manufacture is improved, but the aesthetic appearance and seamless integration is worsened
Solution Approach 1:
The patent extracts the fasteners from the visible exterior and relocates them to the interior structure or uses hidden attachment mechanisms. The fabric cover is attached using concealed fastening methods that maintain aesthetic appearance while preserving ease of manufacture through standardized hidden fastening systems.
Solution Approach 2:
The patent introduces an intermediary fabric layer that mediates between the structural frame and the visible exterior. This fabric intermediary conceals the fastening mechanisms while maintaining the structural attachment, allowing easy assembly through the fabric medium while preserving aesthetic appearance.
3Adaptability or versatility
If the upper back support is made adjustable, then the comfort and adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic adjustability in the upper back support through mechanisms that allow movement between fixed positions. The adjustable frame structure enables the support to change configuration while maintaining structural integrity, providing adaptability through controlled dynamic movement rather than complex continuous adjustment.
Solution Approach 2:
The patent divides the upper back support into segmented sections that can be independently adjusted. This segmentation allows for simplified adjustment mechanisms in each section rather than a single complex mechanism, reducing overall device complexity while maintaining adaptability through modular adjustment capabilities.

AI summary
A decorative closeout assembly includes a gap hider. A U-shaped body portion is constructed from a fabric and includes a plurality of peripheral tabs. First and second inwardly-extending flaps extend inwardly and are operably coupled with a laterally-extending flexible tensioner extending between the first and second inwardly-extending flaps and configured to maintain the body portion taut. A plurality of hooked barbs extend from a bottom side of the U-shaped body portion. An upper back support includes a U-shaped peripheral channel for receiving the plurality of hooked barbs.
