Are Seat Belt Limiters Safe?

[LeonardoDella]

Seat belt limiters have a relatively low safety factor. Here are specific details about safety limiters: 1. Overview: A safety limiter, also known as an overload limiter, is a safety device designed to protect machinery and its users, commonly found in automobiles and cranes. 2. Principle: During the door opening and closing process, the slider inside the limiter cover plate moves back and forth on the main arm. Because the thickness of the main arm varies along the direction of motion, the displacement distance of the slider also varies, resulting in different forces applied to the rubber block. This creates varying door opening and closing forces, thereby achieving the limiting effect. 3. Development Trend: With the growth of the global economy, automobiles will become the primary means of transportation for humans. Due to increasing urban populations, the distance between parking spaces and vehicles will become smaller in the future. To avoid collisions with other vehicles when getting in and out, the requirements for the limiting function of limiters will become higher. Two-stage limiters can no longer meet user demands and will be replaced by three-stage limiters.
