Harness Attachment Eyelet Formed From Webbing Half Hitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety harnesses face challenges in the design of attachment eyelets, which often require additional hardware elements, increasing weight and complexity while compromising strength and resilience.
Innovation Solution
The attachment eyelet is formed from webbing laid in a half loop, integrated into the harness without additional hardware, using configurations such as X-shaped or Y-shaped surfaces to distribute force evenly and prevent seam tearing, with optional reinforcement through sewing and covering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional hardware elements such as D-rings are used to form attachment eyelets, then the attachment point strength is improved, but the weight and device complexity increase
Solution Approach 1:
The invention extracts and eliminates the additional hardware element (D-ring) from the harness system. Instead of using a separate metal component, the attachment eyelet is formed directly from the webbing material itself through a folded and stitched configuration, thereby removing the unnecessary weight of the metal hardware while maintaining the attachment function
Solution Approach 2:
The invention merges the attachment eyelet function with the webbing structure itself. The webbing is folded back on itself to form a loop, and this folded structure is then stitched to create a reinforced attachment point. This combines the structural element (webbing) with the functional element (attachment eyelet) into a single integrated component, eliminating the need for separate hardware
2Strength
If additional hardware elements such as D-rings are used to form attachment eyelets, then the attachment point strength is improved, but the device complexity increases
Solution Approach 1:
The invention removes the separate hardware component (D-ring) from the system, simplifying the overall structure. The attachment eyelet is formed solely from the webbing material through folding and stitching operations, reducing the number of different component types and simplifying the harness construction
Solution Approach 2:
The webbing material serves dual purposes: it provides the structural body of the harness and simultaneously forms the attachment eyelet through its folded configuration. This merging of structural and functional roles into a single component reduces device complexity by eliminating the need for separate attachment hardware
3Strength
If webbing is connected to the harness in the area of an X-shaped surface, then the force transmission is improved and seam tearing is prevented, but the manufacturing complexity increases
Solution Approach 1:
The invention employs an asymmetric X-shaped reinforcement pattern where webbing strips are arranged at specific angles (one pair at approximately 45 degrees, another pair at approximately 135 degrees) to create optimal force distribution. This asymmetric angular arrangement optimizes the mechanical properties for force transmission while maintaining manufacturability through standard stitching patterns

AI summary
The invention relates to a harness for securing individuals, in particular a safety harness, a climbing harness or a seatbelt or harness, having at least one attachment eyelet (20) for a securing means, in particular for a spring hook, the arrangement being such that the attachment eyelet (20) is formed from at least one strap (22) which is formed into a half hitch, such that a loop of the half hitch forms the attachment eyelet (20).
