3. AIRBAG FUNCTION DESCRIPTION
1) Bag (Cushion)
-
The airbag system performance is influenced on the cushion size, shape and position.
-
The cushion strength is a important parameter on the impact absorb effect.
-
Therefore, the control of the airbag performance depends on cushion size, shape, inflator
characteristic and vent hole size for the gas discharge.
The cushion's material and folding function to control the cushion deployment
-
direction and the performance to protect passenger's
2) Airbag Module
3) Module Cover/Housing
-
It is a type of a container that includes the cushion and the inflator.
-
The module housing functions to deliver the reaction force between the body structure and
the airbag (The airbag reaction is absorbed generally to the steering wheel or instrument
panel).
-
The module cover must be considered in a viewpoint of protection between exterior,
internal units and cushion. Also the module cover should be designed not to cause any
personal injury for deployment.
4) Inflator
-
The inflator is a type of the direct gas generated device.
-
The inflator with initial low pressure provides negative restraint effect regarding
passengers moving and time.
On the contrary, the inflator with initial high pressure allows other components of the airbag
to make a excessive impact resulting in any personal injury.
Thus, the inflator output must be optimized according to the characteristic of the vehicle
and passenger moving.
-
The discharge gas has no toxicity or inflammability and also it is the important parameter to
control the high temperature for gas firing.
face.
The driver airbag module is under the center
pad of the steering wheel.
The passenger airbag module is installed in
the instrument panel at passenger side.
The driver and passenger side airbag is
inside each seat.
-
Do not disassemble the airbag module
because unintentional deployment of
the airbags resulting from any damage
or interference of the module can cause
injury.
