21Seat belts
Vehicle occupants not wearing seat belts are not “attached” to the vehicle.
In a head-on collision, they will move forward at the same speed their vehi-
cle was travelling just before the impact. This example applies not only to
head-on collisions, but to all accidents and collisions.
The danger of not using the seat belt
The general belief that the passengers can protect them-
selves with their hands in a minor collision is false.

Even at low speeds the forces acting on the body in a collision are so great
that it is not possible to brace oneself with one's hands. In a frontal colli-
sion, unbelted vehicle occupants are thrown forward and will make violent
contact with the steering wheel, dash panel, windscreen or whatever else is
in the way ⇒ Fig. 8.
The airbag system is not a substitute for seat belts. When triggered, airbags
provide only additional protection. All occupants (including the driver) must
wear seat belts properly at all times during the trip. This will reduce the risk
of severe injuries in the event of an accident – regardless of whether an air-
bag is fitted for the seat or not.
Note that airbags can be triggered only once. To achieve the best possible
protection, the seat belt must always be worn properly so that you will be
protected in accidents in which no airbag is deployed.
It is also important for the rear passengers to wear seat belts properly, as
they could otherwise be thrown forward violently through the vehicle interi-
or in an accident. Passengers in the rear seats who do not use seat belts
endanger not only themselves but also the front occupants ⇒ Fig. 9.
