FUNCTION DESCRIPTION

Back (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 face.

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.

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.

Airbag Module

The driver airbag module is under the center pad of the
steering wheel.
The passenger airbag module is installed in the instru-
ment panel at passenger side.
The driver and passenger side airbag is inside each seat.
Notice
Do not disassemble the airbag module because
unintentional deployment of the airbags resulting from
any damage or interference of the module can cause
injury.
SDM (Sensing and Diagnostic
Module)
1. The airbag system consists of the module section
(driver, passenger and side), seat belt section and
SDM.
2. The SDM has no user-serviceable parts and monitors
the system components continuously. The SDM also
records any faults which are discovered.
3. The SDM allows the fault codes to be retrieved with a
scan tool and illuminates a warning lamp that alerts
the driver to any faults.
The SDM located on floor beneath the floor console
assembly. The SDM performs the following functions:
• Impact decision processor function.
• Determine the airbag deployment through the impact
signal of the accelerometer sensor and the safety
sensor.
