What is the main function of seat belts?

Seat belts mainly serve the following purposes: 1. In emergency situations, they can quickly tighten and restrain the occupant in the seat to ensure safety; 2. They can reduce injuries to drivers and passengers. Seat belts have become a primary consideration for drivers and passengers, and are also one of the important performance features of a car. Traditional components that ensure safe driving include: rearview mirrors and side door mirrors (traditional rearview systems), seat belts, AIRBAG (airbags), and ABS (Anti-lock Braking System). These have become familiar to most drivers and passengers and are widely used in imported luxury cars.
I've been driving for almost ten years, and to me, the seat belt is literally a lifeline. That rainy day when the road was slippery, I had to swerve to avoid a truck and slammed on the brakes. My body lurched forward, but the seat belt locked instantly, holding me firmly in place. Without it, I would have smashed into the steering wheel and suffered serious injuries. Its primary function is to protect drivers and passengers from severe impact during a crash by restraining body movement, preventing you from being ejected or hitting hard objects. Now, buckling up is second nature to me the moment I get in the car, and I always remind my friends to make it a habit. Never think of it as a hassle—safety comes first, no matter what. Imagine even a minor incident on the highway turning into a disaster without a seat belt. Statistics show that seat belts reduce the risk of death by more than half, making them the most practical protection in a car.
From the perspective of vehicle structure, the seat belt's function is to secure the human body and limit your movement range during a collision. Its built-in locking mechanism triggers during sudden deceleration, firmly holding you in place to prevent you from lunging forward into the steering wheel or being thrown and injuring rear passengers. Simply put, it absorbs impact forces during a crash, distributing them across the entire body to significantly reduce injuries. During my auto repair work, I've seen many cases where unbelted occupants sustained severe injuries, while those wearing belts had only minor abrasions. So don’t skip this daily driving step – buckling up is like buying yourself insurance, protecting your neck and chest from major trauma. Remember, the core principle of safety devices is prevention first.
As a parent, I always remind my children that wearing seat belts in the car is crucial for their protection. Its main function is to prevent children from being thrown out of their seats during braking or minor accidents, which could cause head or spinal injuries. I teach them through gamification, saying that seat belts are like superhero armor that can ward off dangers. In real life, the effectiveness is evident even in a rear-end collision—children stay securely in place and won’t hit the front. Developing this habit from an early age can truly prevent tragedies and provide a stronger sense of security.
