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. WebWhile the driver with an airbag may experience the same average impact force as the driver with a good seatbelt, the airbag exerts an equal pressure on all points in contact with it …
