What do safety belts usually consist of?

Safety belts, commonly known as seat belts, typically consist of strong webbing made from nylon or polyester, designed to withstand high forces during a crash. They usually include a buckle for secure fastening and a locking mechanism to keep the belt taut. Additionally, many safety belts feature adjustable lengths to accommodate different body sizes and may include padding for comfort. Some advanced designs also incorporate pretensioners and load limiters for enhanced safety performance.
