Vehicle Multi-Headrest Assembly with Integrated Pivotable Seatback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs lack efficient integration of multi-headrest assemblies and pivotable seatback arrangements, which can compromise safety and aesthetics by allowing gaps between seatback portions and failing to effectively absorb impact energy.
Innovation Solution
A multi-headrest assembly with an elongate crossbar and brackets that supports two headrests, allowing them to be aligned with pivotable seatback portions, and a seatback arrangement where one portion is pivotable relative to the other, with energy-absorbing capabilities to reduce frame impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional separate headrest and seatback designs are used, then manufacturing is simpler, but gaps appear between seatback portions compromising safety and aesthetics
Solution Approach 1:
The patent combines the headrest assembly and seatback arrangement into a single integrated multi-headrest assembly. The crossbar of the headrest mount is continuously connected to the seatback portions, eliminating gaps between components. This merging ensures that impact forces are distributed across the entire assembly rather than being isolated to separate parts, thereby improving safety while maintaining structural integrity.
2Adaptability or versatility
If pivotable seatback portions are added for adjustable configurations, then passenger comfort improves, but the structure becomes more complex
Solution Approach 1:
The patent incorporates pivotable seatback portions that can rotate relative to the seat bottom, enabling adjustable seating configurations for different passenger needs. The dynamic design allows the seatback to move between upright and reclined positions while remaining structurally integrated with the headrest assembly through the continuously connected crossbar, balancing versatility with structural simplicity.
3Reliability
If energy-absorbing capabilities are integrated into the seatback, then impact safety improves, but the device complexity increases
Solution Approach 1:
The patent integrates energy-absorbing capabilities directly into the seatback structure beforehand, allowing the seatback to dissipate impact forces during collisions. The continuously connected crossbar and integrated seatback portions create a unified structure that absorbs and distributes impact energy across multiple components, reducing the force transmitted to the vehicle frame and improving overall safety without requiring separate cushioning systems.

AI summary
A multi-headrest assembly for a vehicle includes first and second headrests for first and second seats of the vehicle, respectively, and a multi-headrest mount having a crossbar and first and second brackets coupled to and spaced along the crossbar for supporting the first and second headrests, respectively. The crossbar has a length for defining a space between the first and second headrests for aligning the first and second headrests with the first and second seats, respectively, when mounted in the vehicle. The multi-headrest assembly further includes first and second seatback portions configured to be coupled to and supported by the first and second brackets, respectively.
