Load limiters are safety devices designed to prevent excessive force or stress on a system, such as in vehicles or machinery. They work by allowing a certain amount of movement or deformation when a specific load is exceeded, helping to protect components from damage. For example, in cars, load limiters can be part of the seatbelt system, reducing the force on passengers during a crash. These devices are crucial in various applications, including automotive safety, industrial machinery, and construction equipment. By controlling the load, they enhance safety and reliability, ensuring that systems operate within their designed limits and reducing the risk of failure.
