WebThe main vehicle safety features are crumple zones , seat belts and airbags. For a given force upon impact, these absorb the energy from the impact and increase the time over which the force takes place. This, in turn, increases the time taken for the change in momentum of the passenger and the vehicle to come to rest. WebApr 9, 2002 · A seatbelt's job is to spread the stopping force across sturdier parts of your body in order to minimize damage. A typical seatbelt consists of a lap belt, which rests over your pelvis, and a shoulder belt, which extends across your chest. The two belt sections are tightly secured to the frame of the car in order to hold passengers in their seats.
