How do seatbelts reduce impact force

WebWhen a car stops or unexpectedly speeds, seat belts provide force to prevent any type of heavy movement. Airbags Airbags are used to provide cushioning and support during a vehicle collision. Often hidden in the front or sides of the vehicle, airbags inflate on impact to help prevent excessive movement and force. WebTypically, a seatbelt will include a 'retractor mechanism' (see Fig. 6) that causes a spring inside the retractor to apply a rotational force to the spool when it is being pulled. This means that the belt tightens once it becomes loose to reduce the amount of 'slack' in the material, helping to secure the passenger to their seat. Fig. 6: Basic seatbelt retractor …
