Seat Belt Buckle: Description and Operation
SAFETY BELT BUCKLE AND PRETENSIONER
The safety belt buckle and pretensioner assembly 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 pretensioner deploy, this causes the buckle 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 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.
For safety belt buckle pretensioner diagnostic information, refer to Air Bag Systems.
For safety belt buckle pretensioner disposal information, refer to Air Bag Systems.
