Headrest Furniture Fitting With Pivot-Extend Upholstery Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture fittings are designed in an effortful and space-consuming manner, often resulting in wrinkles in the upholstery of seating furniture when adjustable head parts are folded out, leading to an unattractive and low-quality appearance.
Innovation Solution
A compact furniture fitting design comprising a support bracket, first, second, and third push elements, where the third push element is longitudinally displaceable and pivotable, allowing for both pivot and extending movements, ensuring the upholstery remains tightly stretched in all states, and enabling both manual and motor-driven adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional furniture fittings are used for head rest adjustment, then the head rest can be adjusted, but wrinkles form in the upholstery leading to unattractive appearance
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the head rest can be positioned at multiple angles and heights. The fitting allows continuous movement along guide rails and pivoting at multiple joints, enabling the head rest to adapt to different positions without creating wrinkles in the upholstery
Solution Approach 2:
The patent introduces intermediary components including guide rails, connecting joints, and cushioning elements between the head rest and the furniture frame. These intermediaries distribute forces evenly and prevent direct contact that would cause upholstery deformation
2Adaptability or versatility
If furniture fittings are designed with multiple movement capabilities (pivot and extending), then adjustment versatility is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal fitting mechanism that performs multiple functions: pivoting, extending, and positioning. The same set of guide rails and connecting joints enables both rotational movement and linear extension, reducing the need for separate mechanisms for each function
Solution Approach 2:
The patent combines multiple movement functions into a single integrated fitting structure. The guide rails simultaneously guide both pivoting and extending motions, and the connecting joints handle multiple degrees of freedom, merging what would otherwise require separate components
3Volume of moving object
If compact furniture fitting design is implemented, then installation space is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the compact fitting into modular segments including separate guide rails, connecting joints, and mounting brackets. Each module is manufactured independently with standardized dimensions, allowing precise assembly while maintaining overall compactness. The modular design enables manufacturing tolerances to be managed at each component level rather than requiring extreme precision across the entire assembly

AI summary
The present disclosure relates to a furniture fitting comprising a support bracket, a first push element, a second push element, which is pivotable with respect to the first push element, and a third push element, which is longitudinally displaceable with respect to the second push element and pivotable with respect to the first push element, wherein a longitudinal displacement of the first push element effects a pivoting movement of the second push element with respect to the first push element and an extending movement of the third push element resulting therefrom. The present disclosure further relates to an arrangement comprising two furniture fittings and to beneficial uses of furniture fittings.
