How SRS works
When the ignition switch is placed to
"ON" position, SRSCM monitors
collision sensor signals and all parts
to judge whether the airbag is
needed to be expanded according to
the severity of front collision.
When the ignition switch is placed to
"ON" position or the engine is
started, the SRS warning light on the
console flashes for 6s, and then is
off.
When SRSCM detects that the
energy generated by front collision is
sufficiently big, the airbag expands
automatically.
When the airbag expands, the liner
cover in front of the airbag is torn and
detached with the action of expansion
pressure. Only when the liner cover is
torn securely, the airbag can expand
completely to provide protection. The airbag that expands completely
in combination with the safety belt
tensioner can reduce the forward
force of the driver and occupants, so
as to reduce the risk of injury to
head and chest.
The airbag shrinks immediately after
it expands, with an interval of about
0.1s. This will not hinder the driver's
line of sight.
