Examples of impact detection zones
Front airbags and knees airbags
For these airbags to deploy, it
requires a violent frontal impact
applied on all or part of the frontal
impact zone (see illustration) from
forward of the vehicle in a horizontal
plane.
The airbag interposes itself between
the vehicle's front occupant and the
dashboard to cushion the person
from being thrown forward. The air-
bag thus limits the risk of trauma to
the head and chest. For the driver,
the knees airbag protects the knees.
The front passenger's airbag can be
deactivated. see "Passenger's air-
bag deactivation".

Side airbags and curtain airbags
Deployment of these airbags requires
a violent lateral impact applied on all
or part of one of the lateral collision
zones, coming in a horizontal plane
from the side.
The role of the side airbag is to
place itself between the occupant
(driver or front passenger) and the
door panel, thus limiting the risk of
injuries to the chest.
The role of the curtain airbag is to
place itself between the front or
rear occupant and the windows,
thus limiting the risk of injuries to
the head.
These airbags may not deploy if
there is only a slight collision on the
side of the vehicle, or if the vehicle
rolls over. They will not deploy for a
front or rear collision.
