2. FUNCTION DESCRIPTION
1) 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.
2) 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.
3) 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.
