WARNING (Continued)■Many layers of clothing and loose clothing (e. g. a winter coat over a jack-
et) do not allow you to be correctly seated and impairs proper operation of
the seat belts.■
Do not use clamps or similar items, which prevent the lash-lock function
of the seat from operating. A seat belt which is hanging too loose can re-
sult in injuries, as your body is moved forward by the kinetic energy pro-
duced in an accident and is then abruptly held firm by the belt.
■
The seat belts for the rear seats can only fulfil their function reliably
when the seat backrests are correctly locked into position » page 74.
WARNINGInformation on the care and maintenance of the safety belts■The belt webbing must always be kept clean. Soiled belts may impair
proper operation of the inertia reel » page 147.■
The seat belts must not be removed or changed in any way. Do not at-
tempt to repair the seat belts yourself.
■
Check the condition of all the seat belts on a regular basis. If any damage
to the seat belts, seat belt connections, inertia reel or the lock is detected,
the seat belt concerned must be replaced by a specialist garage.
■
Damaged seat belts which have been subjected to stress in an accident
and were therefore stretched, must be replaced - this is best done by a
specialist garage. The anchorage points of the belts must also be inspec-
ted. The anchorage points for the belts should also be checked.
Note
The national legal requirements must be observed when using seat belts.The physical principle of a frontal collisionFig. 4

on page 12 first.
As soon as the vehicle is moving, so-called kinetic energy (the energy of mo-
tion) is produced, both in terms of the car as well as in terms of the occupants.
The magnitude of this kinetic energy depends essentially on the speed at
which the vehicle is travelling and on the weight of the vehicle, including the
occupants. The greater the speed and weight increase, the greater the
amount of energy which has to be absorbed in the event of an accident.
The speed of the vehicle is the most important factor. Doubling the speed of
the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four
times.
The notion that it is possible to support your body with your hands in a minor
accident is incorrect. Even in a collision at only a low speed, the forces acting
on the body are such that it is no longer possible to support your body.
Even if you only drive at a speed of 30 km/h to 50 km/h, the forces that your body is exposed to in the event of an accident can exceed a ton (1,000 kg).
For example, a person's weight of 80 kg “increases” at 50 km/h to 4.8 tons (4,800 kg).
In the event of a frontal collision, occupants of the car not wearing a seat belt
are thrown forward and strike parts of the interior of the car, such as the
steering wheel, dash panel, windscreen in ways which cannot be controlled
» Fig. 4 -
. In certain circumstances, you could even be thrown out of the ve-
hicle, which could cause life-threatening or even fatal injuries.
