Seat belt
Why is it necessary to wear seat belts?
The physical principle of the frontal collision
Properly wearing a seat belt can effectively
reduce the possibility of injuring the driver
and passenger in an accident.
Seat belts can slow down the driver’s inertia
and reduce the impact injury to the driver as
much as possible in the event of a frontal
collision.
The vehicle and occupant in the process of
running have energy (kinetic energy), its
strength depends on the speed of the vehicle
and the mass of occupant, the greater the
speed and mass, the stronger the energy
released in the collision. The speed plays a
decisive role. If the speed is increased from
25 km/h to 50 km/h, the release of kinetic
energy will increase fourfold. After the
vehicle collision, the occupant without the
seat belt will still move forward at the speed
before the collision due to inertia, but the
vehicle is not moving with the occupant at
this time. The crew could be seriously injured.
DANGER
• Drivers and occupants should use
seat belts properly at all times.
Failure to do so will increase the
likelihood or severity of injury in an
accident.
• When a vehicle is in motion, wearing
a seat belt properly will ensure an
emergency brake or reduce the risk
of injury to the driver and passenger
in the event of an accident.
• Pregnant women and people with
disabilities should also use seat belts
correctly.
• Seatbelts should not be shared, even
among children.
• Avoid overreclining the seat back.
When a vehicle is involved in a
frontal collision, the more reclined
the seat, the greater the chance of
serious injury or death.
DANGER
• Check the seat belt system regularly.
If the safety belt system is found to
be nicked, worn or loose, the safety
belt assembly or assembly must be
replaced. Do not disassemble or
modify the safety belt system.
• Keep seat belts clean and dry. If you
need to clean the belt, use a neutral
soap solution or warm water. Do not
use bleach, dye or detergent to clean
the seat belt.
• Seat belts (including bolts) used in a
serious crash must be replaced. The
entire assembly should be replaced
even for minor damage.
