Vehicle Seatback Panel Assembly for Headrest Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When vehicle seating assemblies are folded forward, cargo can topple into gaps between rows, and may damage the exterior of the headrest, as existing designs do not effectively cover these gaps or protect the headrest from cargo impact.
Innovation Solution
A vehicle seating assembly design featuring a panel assembly that protrudes forward of the headrest when the seatback is folded, with a second panel translating from a first panel, and a locking feature to resist movement, allowing the panel assembly to extend and contract to cover gaps and protect the headrest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the seatback is folded forward to optimize cargo space, then cargo space is improved, but gaps appear between seating rows allowing cargo to topple through and the headrest exterior becomes vulnerable to damage
Solution Approach 1:
A panel assembly acts as an intermediary component between the folded seatback and the headrest. The panel extends forward from the headrest to fill the gap created by folding, preventing cargo from reaching the headrest while maintaining cargo space utility. The panel serves as a protective mediator that addresses both the cargo space requirement and the headrest protection need.
Solution Approach 2:
The panel assembly is designed to be dynamically extendable and retractable relative to the headrest. When the seatback is folded, the panel extends forward to cover gaps and protect the headrest. When the seatback is upright, the panel retracts. This dynamic adjustment allows the system to adapt to different seating configurations and provide protection only when needed.
2Object-affected harmful factors
If a fixed panel is attached to the headrest to cover gaps, then headrest protection is improved, but the device complexity and difficulty of adaptation to different configurations increases
Solution Approach 1:
The panel assembly incorporates telescopic or sliding mechanisms that allow it to extend and retract relative to the headrest. This dynamic capability enables the panel to adapt to different seatback positions (folded vs. upright) without requiring a completely different structure for each configuration, thereby reducing overall system complexity while maintaining protection functionality.
Solution Approach 2:
The panel assembly serves multiple functions: it protects the headrest from cargo damage, covers gaps between seating rows, and can be adjusted to work with both folded and upright seatback positions. This multi-functionality reduces the need for separate components for each function, thereby simplifying the overall device complexity.
3Adaptability or versatility
If a telescopic panel assembly is used to cover gaps, then adaptability to different vehicle configurations is improved, but the device complexity increases due to additional moving parts
Solution Approach 1:
The telescopic panel assembly uses simple extendable mechanisms that allow it to adjust its length to match different vehicle configurations and seatback positions. The telescopic design provides adaptability through length adjustment while using straightforward mechanical principles that minimize structural complexity.
Solution Approach 2:
The telescopic panel assembly likely employs a nested structure where one panel is inserted within another, similar to nested dolls. This nesting approach allows the panel to compactly store when not in use while providing extended coverage when needed, achieving adaptability without requiring separate components for each configuration state.

AI summary
A vehicle is provided herein. The vehicle includes a first seating assembly and a second seating assembly. The first seating assembly is positioned vehicle rearward of the second seating assembly and is comprised of a seatback pivotally coupled to a seat-base, a headrest coupled to the seatback via a connecting feature, and a panel assembly coupled to the connecting feature. The seatback is operable between a folded position and an unfolded position. The panel assembly is configured to protrude vehicle forward of the headrest when the seatback is in the folded position.
