Seat, seatbelt and SRS airbags

After deployment, the SRS airbag immediately starts to deflate so that the driver’s
vision is not obstructed and the driver’s
ability to maintain control of the vehicle is
not impaired. The time required from
detecting impact to the deflation of the
SRS airbag after deployment is shorter
than the blink of an eye.

level of force experienced in the passenger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on
the visible damage done to the vehicle
itself.

! Example of accident in which the
driver’s/driver’s and front passenger’s SRS frontal airbag(s) will most
likely deploy

Both when only the driver’s SRS frontal
airbag deploys and the driver’s and front
passenger’s SRS frontal airbags deploy,
the driver’s and front passenger’s seatbelt
pretensioners operate at the same time.
The driver’s SRS frontal airbag and front
passenger’s SRS frontal airbag are designed to deploy in the event of an
accident involving a moderate to severe
frontal collision. They are not designed to
deploy in most lesser frontal impacts
because the necessary protection can be
achieved by the seatbelt alone. Also, they
are not designed to deploy in most side or
rear impacts or in most roll-over accidents
because deployment of only the driver’s
SRS frontal airbag or both driver’s and
front passenger’s SRS frontal airbags
would not help the occupant in those
situations. The driver’s and front passenger’s SRS frontal airbags are designed to
function on a one-time-only basis.

A head-on collision against a thick concrete wall at a vehicle speed of 12 to 19
mph (20 to 30 km/h) or higher activates
only the driver’s SRS frontal airbag or both
driver’s and front passenger’s SRS frontal
airbags. The airbag(s) will also be activated when the vehicle is exposed to a
frontal impact similar in fashion and
magnitude to the collision described
above.

SRS airbag deployment depends on the
