Description

BACKGROUND

[0001] A seat belt buckle, also known as a webbing-type buckle, is a critical component in various safety and restraint applications, most notably in automotive seat belts. The seat belt buckle may be designed to securely fasten and release webbing straps, ensuring the safety and comfort of the user. Additionally, the seat belt buckle may be engineered to withstand significant forces while providing ease of use and reliability.

[0002] In the automotive industry, the integration of seat belt reminders into the seat belt buckle system has become increasingly common. While this advancement significantly enhances safety, it also introduces a new challenge: the wiring harness is exposed to the full range of customer movements. Over time, these movements may lead to the breakage of the electrical wires or cables inside the wiring harness, compromising its durability and functionality. The wiring harnesses may be prone to bending over sharp edges or adopting a minimal bend radius, eventually leading to their premature failure.

[0003] Conventionally, recessing the seat belt buckle system into the cushion or adding a linkage system may limit customer interaction with the seat belt buckle. However, these methods tend to reduce usability and substantially increase the overall cost of the system. Thus, increasing the bend radius is one way to improve the durability of the wiring harness. This necessitates developing a seat belt buckle that promotes a larger bending radius. The seat belt buckle must resist sharp bending and improve the longevity of the wiring harness.

[0004] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with few aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings. SUMMARY

The hollow flexible loop 114 may be essential in various applications to ensure safety, durability, and efficiency of electrical systems.

[0024] The hollow flexible loop 114 may function as a protective covering to insulate, organize, and safeguard the plurality of electric wires or cables. In some instances, the hollow flexible loop 114 may be used in a different vehicle system, such as but not limited to, Electronic Stability Control (ESC), Anti-lock Braking System (ABS), Airbags, Tire Pressure Monitoring System (TPMS), Power Management System, Communication Systems, Infotainment System, Climate Control System, Ignition System, or Charging System.
