Seat Belt Tensioner: Description and Operation
Supplemental Restraint System
SAFETY BELT PRETENSIONERS
The front outboard safety belt retractors use a safety belt pretensioner system. This works in conjunction with the front air bag system mounted in the
steering wheel and instrument panel. The pretensioner is a pyrotechnic device that removes excess webbing slack from the safety belt. The pretensioners
are activated by the restraints control module (RCM) when the module detects a frontal impact force exceeding a programmed limit. If the vehicle is
involved in a collision that results in deployment of the safety belt pretensioners, a new driver and passenger seat belt system (including safety belt
buckle and pretensioners or safety belt retractor and pretensioners, safety belt retractors, safety belts, buckles and height adjusters), must be installed.
