SYSTEM DIAGRAM

DESCRIPTION

Supplemental Restraint System (SRS) activates the air bag module and seat belt pre-tensioner when it

detects a frontal collision or a side collision that is more than the specified limit.

Together with other safety devices, it reduces the impact that occupant receives when vehicle collision occurs.

Air bag diagnosis sensor unit supplies power supply to air bag module and pre-tensioner seat belt when decel-

eration that is more than the specified limit is detected by G sensor in air bag diagnosis sensor unit, crash

zone sensor, satellite sensor, or front door satellite sensor.

Air bag module is composed of electric igniter (squib), filter, pyrotechnic material, and gas generating material.

When air bag module receives a signal from air bag diagnosis sensor unit, air bag module ignites pyrotechnic

material using electric igniter (squib) so that gas generating material generates high temperature nitrogen gas.

The gas through filter activates air bag. At the same time, pre-tensioner seat belt receives power supply from

air bag diagnosis sensor unit, gas generator is activated, and then gas is generated.

Balls in pipe are moved according to generated gas pressure and strike pinion gear on ELR shaft.

ELR shaft rotates and retracts seat belt.
