What Principle Does the Seat Belt Utilize?
1 Answers
Automotive seat belts are devices installed in vehicles to ensure the safety of passengers and drivers by preventing injuries caused by the deployment of airbags during a severe collision. The working principle is as follows: 1. The seat belt mechanism contains a locking wheel. In the event of a rapid pull on the seat belt, such as during a car accident, the internal locking mechanism is activated by centrifugal force due to the rapid rotation of the belt's roller, swiftly locking the seat belt to secure the occupant in place. 2. Once the peak impact has passed or when the occupant is adequately protected by the airbag, the seat belt loosens to prevent rib injuries. This series of actions collectively serves to safeguard the vehicle's occupants.
