Seat belt
The seat belt is a safety device
that ensures that the driver and
occupants are restrained in a
limited position during a vehicle
collision, emergency braking,
and sudden steering. We
strongly recommend that
drivers and occupants wear
seat belts correctly at all times
to reduce the forward inertia of
drivers and occupants caused
by collisions, emergency
braking and sudden steering.
Correct use of seat belts can
greatly reduce the casualties of
occupants in the vehicle.
The protective
effect of seat belts
When you are sitting on or in
an object, you will move at the
same speed as the object.
Take the simplest vehicle as an
example, suppose that the
vehicle is a seat with wheels on
which a person can sit. Make it
accelerate and then stop, the
people in the vehicle will not
stop.
