Safety Belt Buckle Pretensioner

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

A SuperCab vehicle with seat integrated restraints (SIR) is equipped with safety belt buckle pretensioners. These are for the front outboard occupants, located on the inboard side of the seats. To identify a SIR seat, refer to SEAT INTEGRATED RESTRAINTS (SIR) IDENTIFICATION .

The safety belt buckle pretensioner is a pyrotechnic device that removes excess webbing from the safety belt system. When the front air bag system is deployed, the pretensioner in the buckle deploys, causing the buckle to move downward, pulling excess webbing from the lap and shoulder safety belts.
