A pyrotechnic front seat belt pre-tensioning device with independent el ectronic sensing and retractor unit is installed at the
base of each 'B' post. In the event of se vere frontal impact, this provides additional front occupant protection by removing
any excess slack from the seat be lt. Seat belt pre-tensioning activates when a frontal impact of sufficient force occurs within
30 degrees of vehicle center line. Under such an impact, el ectronic sensors in the retractor unit fire, igniting the pre-
tensioner gas generator. The ga s generator initiates a chemical reaction, producing gases under pressure. Gas pressure
drives the piston/cable up a tube, rotating the retractor sp indle and removing excess slack from the seat belt. When the
pre-tensioner unit has been activated, the seat belt will lock and cannot be retracted or pulled from the reel.If a seat belt
pre-tensioner activates, a small quantity (less than 1 liter) of gas is produced containing nitrogen, oxygen and water vapor.
