AIRBAG SYSTEM

PRINCIPLE OF SRS SYSTEM
When the vehicle collision happens, the collision
between the vehicles or between the vehicle and the
barrier is called the first collision. After the first
collision, the vehicle speed changes rapidly. The
driver and the passengers will move forward due to
the inertia, and will collide with the steering wheel,
windshield or instrument dashboard etc. This
collision is called the second collision. The main
reason that caused the driver's injury in the accident
is the second collision. In order to reduce or avoid
the driver's injury in the second collision, the vehicle
has installed with the passive protection devices of
seat belt and safety airbag. The airbag is an option
for the Chery sedan A15 RHD, and the airbag model
employed is Dongfangjiule.
The purpose of the airbag design is: During the short
Activated airbag system
period between the first and the second collisions
(50ms), quickly insert an airbag between the driver
and the interior structures of the car, as shown in the
Figure:
The driver's head and chest will press on the air
filled cushion. The air bag can absorb the kinetic
energy aroused by the inertia of the human body by
the damping effect of itself so as to protect the
personal safety.
The airbag system is a kind of safety device used
together with the seat belt.
The airbag can not replace the function of the seat
belt.
The driver must put on the seat belt at all time and
adjust the seat belt to a proper tension.
