Seat Belt Tensioner: Description and Operation
Supplemental Restraint System
Safety Belt Buckle Pretensioners - All Vehicles
SAFETY BELT BUCKLE PRETENSIONERS - ALL VEHICLES
As part of the SRS, the safety belt buckles are equipped with pretensioners. The safety belt buckle pretensioners remove excess slack from the safety belt
webbing. The pretensioners are activated by the restraints control module (RCM) when the module detects a impact event force exceeding a programmed
limit.
Safety Belt Tension Sensor
SAFETY BELT TENSION SENSOR
The safety belt tension sensor is used by the occupant classification sensor (OCS) system to identify the presence of a child safety seat on the front
outboard passenger seat, when the child safety seat is installed according to manufacturer instructions. The safety belt tension sensor senses the tension
on the safety belt assembly then provides an output to the OCS system electronic control unit (ECU), indicating that the safety belt assembly is cinched.
After sensing the weight applied to the seat by the occupant and using the safety belt tension sensor input, the OCS system determines how the occupant
should be classified and communicates this information to the restraints control module (RCM). If the occupant is classified to be a child, the RCM will
then automatically deactivate the passenger air bag module.
The safety belt tension sensor:
-
is part of the front outboard passenger safety belt and retractor assembly.
-
is located at the safety belt anchor point.
-
is used in conjunction with the OCS system.
-
is a 3-wire Hall-effect sensor that is part of the front passenger safety belt and retractor assembly.
