Small toothed belts are typically made from high-quality synthetic rubber, reinforced with materials like fiberglass or steel to enhance durability and strength. The teeth on the belt can vary in shape and size, with common profiles being trapezoidal or rounded. The choice of tooth design impacts not only the belt's performance but also its noise level and wear characteristics. Additionally, these belts come in a variety of widths and lengths, allowing engineers to select the perfect specification for their particular application.

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.

This simple mechanism can effectively prevent injuries that might otherwise occur during a crash.
