What is the purpose of seat belts?

The purpose of seat belts is to keep occupants safe in the event of a collision. When a vehicle is involved in an accident, the sudden deceleration can cause unrestrained passengers to be violently thrown around inside the vehicle or even ejected from it. Seat belts are designed to restrain the occupants, preventing them from being thrown forward or out of the vehicle, significantly reducing the risk of injury or death during a crash.

By securely holding the occupants in place, seat belts also work in conjunction with airbags, helping to ensure that a person's body is properly positioned to receive the protection offered by these safety devices. The use of seat belts is a fundamental aspect of vehicle safety and plays a critical role in enhancing the overall safety of passengers.
