How side curtain airbags work
Side curtain airbags can work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained.
Fig. 160 Il lus tr ation of principle: Inflat e d side curtain
airbags o n th e left side
The side curtain airbags inflate between the
occupant and the windows on the s ide of the
vehicle that is struck in a side coll is ion
~ fig. 160.
When the system is trigge red, the side curta in
airbag is filled with prope llant gas and breaks
t hrough a seam above the front and rear side
windows iden t ified by t he AIRBAG labe l. In or-
der to he lp prov ide this additional protection,
the side curtain ai rbag m ust inflate within the
blink of an eye at very high speed and with
great force. The side curtain a irbag could in-
jure you if your seating position is not proper
or upright or if items a re located in the area
where the supplemental
side curta in a irbag
inflates . This applies especially to ch ild ren
~ page 167 .
Although they are not a soft pillow, side cur-
ta in a irbags can "cushion " the impact and in
th is way they can help to reduce the risk of in-
jury to the head and the uppe r part of the
body .
A f ine dust may deve lop when the airbag de-
ploys . This is quite normal and does not mean
there is a fire in the vehicle.
