What is the primary function of seat belts?

The primary function of seat belts is to keep occupants securely in their seats and reduce the risk of injury in a crash. When a vehicle is involved in an accident, the sudden deceleration can cause unrestrained passengers to be thrown forward at high speeds, potentially leading to severe injuries or fatalities. Seat belts are designed to restrain occupants, preventing them from being ejected from the vehicle and minimizing the force exerted on their bodies during a collision. By securely fastening individuals to their seats, seat belts play a crucial role in enhancing the overall safety of everyone in the vehicle, making them a vital component of automotive safety systems.
