What is the main function of seat belts?

Seat belts function to restrain the driver and passengers in their seats during sudden braking or unexpected situations, preventing them from being thrown forward and thereby protecting them from injuries caused by secondary collisions. Relevant information about car seat belts is as follows: Introduction: Car seat belts are safety devices installed on vehicle seats. Working Principle: The retractor contains a ratchet mechanism. Normally, occupants can pull the webbing freely and at a constant speed, but when the webbing stops being pulled out continuously or when the vehicle encounters an emergency, the ratchet mechanism locks automatically, preventing the webbing from being pulled out further.
The primary function of seat belts is to prevent you from being ejected from the vehicle or colliding with interior components during a crash, protecting you from serious injuries. Having driven for many years, I've experienced sudden braking and rear-end collisions, and each time I fasten the belt, I feel much more secure. It keeps you firmly in your seat, dispersing the force of impact to prevent your body from flying uncontrollably and hitting the windshield or steering wheel. Crucially, it works in tandem with airbags—when the airbag deploys, the seat belt stabilizes you, preventing the airbag from injuring your face or chest. Numerous statistics show that properly wearing a seat belt can reduce the risk of death by more than half. Some people find it uncomfortable and skip it, especially on short trips, but in reality, accidents often happen close to home. Developing the habit is key. I remember last year when I almost had a collision on the highway, the belt held me in place, resulting in only minor scrapes—otherwise, the consequences could have been severe. I truly hope more people realize that a seat belt isn't just a strap—it's a lifesaver.
