Safety Harness Binding Strap Attachment Eyelet Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety harnesses face challenges in effectively anchoring securing devices due to limitations in the design of attachment eyelets, which can be costly and complex to produce.
Innovation Solution
The attachment eyelet is formed by a binding strap connected to and enclosing a predetermined section of the belt, with optional ring-shaped configurations and additional edging straps for enhanced strength and force distribution, allowing for easy integration with the belt's edging and reduced material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional attachment eyelets are used in safety harnesses, then anchoring strength is maintained, but production cost and complexity increase
Solution Approach 1:
The binding strap that forms the attachment eyelet is merged with the edging strap that borders the belt. The same continuous strap performs both functions: edging the belt and forming the attachment eyelet through detachment and reconnection, eliminating the need for separate components and reducing production complexity
Solution Approach 2:
The binding strap is segmented into different functional sections: a first section that encloses the belt for edging, a second section that is detached to form the attachment eyelet, and potentially a third section that reconnects. This segmentation allows the single strap to create a reliable anchoring structure while maintaining ease of manufacture
2Device complexity
If a single binding strap forms the attachment eyelet, then production is simplified, but anchoring strength may be insufficient
Solution Approach 1:
The binding strap exhibits local quality variations through its different sections. The section enclosing the belt provides edging function, while the detached section provides anchoring function. The strap can be reinforced at specific locations (such as wider sections or additional stitching) where strength is most needed, while maintaining simplicity in other areas
3Ease of manufacture
If the binding strap is detached from the belt over a short section, then production is easier, but the attachment eyelet diameter is reduced
Solution Approach 1:
The binding strap is designed with predetermined detachment and reconnection points that are established during manufacturing. The strap length and detachment section length are pre-calculated to ensure the resulting attachment eyelet has sufficient diameter for its intended use, eliminating the need for complex field adjustments

AI summary
The invention relates to a harness for personal safety, particularly a safety harness, climbing harness, or seat harness, particularly for a carabiner, wherein the belay device is disposed on a belt of the harness and the belt is enclosed by a first enclosing band that forms the load-bearing portion of said belt. The arrangement is made such that the belay device is formed by at least one enclosing band, which is connected to the belt by a predetermined section so as to enclose said belt, and which is released from the belt via another predetermined section.
