Supplemental Restraint System (SRS)
Inflator
The inflator has a squib, ignition cord (fuse), priming
powder, gas generator, filter, etc. put in an aluminum
container and is installed inside the air bag module.
On one side of the inflator is the harness through
which an ignition current flows. When the current
flowing through the harness reaches the squib, a
small quantity of powder is burned to ignite the
ignition cord. The cord burns the priming powder
and the generated heat causes the gas generator
to burn. Combusion of the gas generator produces
\
nitorogen gas quickly, which is sent to the inside
of the air bag through the filter.
d
The filter eliminates cinders, lowers the gas tempera-
ture and reduce the gas generator noise.
The inflator has a shorting clip provided at the con-
nector of the squib harness in the same manner
as the driver’s side inflator.

Air bag deployment [in case of 50 km/h (30 mph) frontal
impact]
(1) OPERATION FOR APPROXIMATELY 15 MILLISECONDS
AFTER THE COLLISION
If a strong impact produced by a collision is detected by
either of the front impact sensors and the safing impact
d
sensor in approximately 10 milliseconds after the collision,
the SRS diagnostic unit will supply an ignition signal to
the squib.
In approximately 3 milliseconds after the ignition signal
has been supplied to the squib, gas generation will begin.
