Reference: OCR
Crumple zones, seat belts and airbags are designed to extend the stopping time, spreading the same change in velocity over a longer time to reduce the force.
A seat belt or crumple zone increases the time taken to decelerate, reducing the deceleration and therefore the force on the passenger.
