Seat belt pretensioners (front seats)
Pre-crash seat belts (front seats of vehicles with pre-crash safety
system)
If the pre-crash sensor detects that a collision is unavoidable, the pre-
crash safety system will retract the seat belt, thus enhancing the
effectiveness of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 307)

The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal or
side collision.
The pretensioner does not acti-
vate in the event of a minor frontal
impact, a minor side impact, a
rear impact or a vehicle rollover.
