Retractable Headrest Automatic Pivoting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automobile vehicle seat headrests fail to improve driver visibility when not in use, as they do not effectively pivot to a non-use position that enhances rear visibility and can obstruct the pivoting of the seat back, violating safety standards and causing discomfort.
Innovation Solution
A headrest design featuring a rod with pins and a U-shaped portion, elastic return means, and locking mechanisms that automatically pivot the body from a use to a non-use position, allowing the headrest to be driven closer to the seat back, thus improving visibility and satisfying safety standards, with a simple and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the headrest is positioned close to the seat back to improve driver visibility, then visibility is improved, but the headrest may obstruct the pivoting of the seat back
Solution Approach 1:
The headrest is designed with dynamic positioning capability, allowing it to pivot between use position and non-use position. The automatic pivoting mechanism enables the headrest to adapt its position based on whether it is being used, resolving the contradiction between improving visibility when not in use and avoiding obstruction during seat back pivoting operations.
2Reliability
If the headrest is designed to automatically pivot to non-use position when driven into seat back, then visibility and safety standard compliance are improved, but device complexity increases
Solution Approach 1:
The headrest incorporates self-service mechanisms including elastic return means that automatically return the headrest to non-use position, and locking means that automatically engage to secure the headrest in use position. These self-acting mechanisms reduce the need for complex external control systems while ensuring reliable operation and safety standard compliance.
3Ease of manufacture
If the headrest structure is simplified to reduce manufacturing cost, then manufacturing cost is reduced, but the ability to automatically pivot and lock may be compromised
Solution Approach 1:
The invention employs simple, cost-effective components such as elastic return means and basic locking mechanisms that can be manufactured at low cost. These components perform the automatic pivoting and locking functions reliably without requiring expensive materials or complex manufacturing processes, thus maintaining both affordability and automated functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The headrest enhances driver visibility by automatically pivoting to a non-use position, reducing bulk, and ensuring compliance with safety standards, while maintaining a low manufacturing cost and user convenience.
Implementation Method 1
The headrest comprises elastic return means linked to the body and capable of exerting an urge on the rod which tends to pivot the body with respect to the rod to bring the body to the non-use position from the use position

AI summary
A headrest for a seat back for a seat back of an automobile vehicle seat, comprising a rod, likely to be at least party driven into the seat back, and a body linked to the rod. The rod is linked to a lower portion of the body by a pivoting link and the headrest comprises means, triggered by a driving of the rod into the seat back down to a driving-in position, capable of automatically pivoting the body with respect to the rod from a use position to a non-use position.
