When
an
impact
greater
than
a
set
level
is
applied
to
the

front
of
the
vehicle,
the
sensor
senses
it
and
generates
an
electrical
pulse
to
inflate
the
bag
in
the
airbag
module,
thuspreventing
the
upper
bodies
of
the
driver
and
passenger
in
the
front
seat
from

is
the
magnet
piston
type
sensor
.

the
sensor
receives
a
frontal
impact
exceeding

a
certain
limit,
the
mass
in
the
sensor
moves
forward
to
turn
the
switch
ON
.

The
electric
sensor
consists
of
a
piezo-electric
device
and
generates
a
voltage
corresponding
to

the
deceleration
speed
that
occurs
in
