Safety Belt Retractor and Pretensioner

SAFETY BELT RETRACTOR AND PRETENSIONER

The safety belt retractor and pretensioner is a pyrotechnic device that removes excess webbing from the safety belt when deployed. The pretensioner works in conjunction with the front air bag system. When the front air bags deploy, the pretensioners deploy, causing the retractor to move downward, removing excess webbing from the lap and shoulder safety belts.

If the vehicle is involved in a collision that results in deployment of the front air bags and safety belt pretensioners, a new driver and passenger seat belt system (including safety belt buckle and pretensioners, safety belt retractors and height adjusters) must be installed.
