Top Tether Strap Structure With Audible Tension Indication

The patent replaces the visual color change indication system with an electronic detection system. A switch (electronic component) is positioned to be contacted by the connecting member when the top tether strap reaches proper tension, converting the mechanical tension state into an electrical signal that triggers an audio reminder. This substitution eliminates reliance on visual perception and provides accurate, unambiguous indication regardless of lighting conditions.

The system is designed to be self-activating and self-indicating. The connecting member itself serves as the actuator that directly contacts the switch when proper tension is achieved, eliminating the need for separate sensors or complex detection mechanisms. The audio reminder device automatically activates upon switch contact and provides clear indication to the user. This self-service approach minimizes the need for additional control systems or manual intervention, keeping the overall system complexity low while achieving high determination accuracy.
