Ensure that the seat belts can be fastened
at all times and are not damaged.
the buckle could cause severe injuries in
the event of an accident. Therefore, you
must check the condition of all seat belts
at regular intervals.
WARNING
●
●
If seat belts are worn incorrectly or not at
all, the risk of severe injuries increases. The
optimal protection from seat belts can be
achieved only if you use them properly.
Seat belts which have been worn in an
accident and have been stretched must be
replaced by a specialised workshop. Re-
newal may be necessary even if there is no
apparent damage. The belt anchorage
should also be checked.
●
Never allow two passengers (even chil-
dren) to share the same seat belt.
●
Do not attempt to repair a damaged seat

The belts must be kept clean, otherwise
fragile objects (such as glasses or pens,
etc.) because this can cause injuries.
The effects of the laws of physics in the case
of a head-on collision are easy to explain: the
moment a vehicle starts moving, a type of en-
ergy called “kinetic energy” starts acting on
both the vehicle and its passengers.
the retractors may not work properly.
●
Do not allow the seat belt to be damaged
or jammed, or to rub on any sharp edges.
Head-on collisions and the laws of
physics
●
Never wear the seat belt under the arm or
in any other incorrect position.
The amount of “kinetic energy” depends on
the speed of the vehicle and on the weight of
the vehicle and of its passengers. The higher
they are, the more energy there is to be “ab-
sorbed” in the event of an accident.
●
Bulky and unfastened clothing (such as
an overcoat over a sweater) impairs the
proper fit and function of the seat belts, re-
ducing their capacity to protect.
●
The slot in the seat belt buckle must not
The most significant factor, however, is the
speed of the vehicle. If the speed doubles
from 25 km/h (15 mph) to 50 km/h (30 mph),
for example, the corresponding kinetic ener-
gy is multiplied by four.
be blocked with paper or other objects, as
this can prevent the latch plate from en-
gaging securely.
●
Never use seat belt clips, fastening rings
or similar items to alter the position of the
belt webbing.
Given that the passengers of the vehicle in
our example do not have their seat belts fas-
tened, in the event of a collision the entire
