Silent sync belts are a type of synchronous belt, also known as timing belts. Unlike traditional belts, which can create significant noise during operation, silent sync belts utilize advanced materials and designs to minimize sound. They achieve this by utilizing specially shaped teeth that engage more quietly with pulleys. Furthermore, these belts are constructed of durable material, often reinforced with fiberglass or aramid fibers, which not only extends their lifespan but also enhances their performance under load.

Modern seat belts consist of a webbed fabric strap, a buckle, and a retractor mechanism that allows the belt to extend and retract. The three-point design encompasses the user's shoulder and lap, distributing the force of a collision across the stronger parts of the body. In the event of an accident, the seat belt restrains the occupant, preventing them from being thrown forward. This simple mechanism can effectively prevent injuries that might otherwise occur during a crash.
