Abstract
A tension sensing assembly for a seat restraint system in a vehicle includes a sensor plate adapted to be fixed relative to vehicle structure and a movable anchor plate adapted to be connected to belt webbing and movable relative to the sensor plate. The tension sensing assembly also includes a housing mounted to the sensor plate and a movable actuator disposed in the housing. The tension sensing assembly includes at least one spring disposed between the housing and the actuator. The tension sensing assembly further includes at least one magnet and a Hall effect sensor mounted to either one of the housing and the actuator. The anchor plate has a tab portion extending through the housing and cooperable with the actuator to move the actuator to deflect the at least one spring. The actuator moves to change a distance between the at least one magnet and the Hall effect sensor to change an output of the Hall effect sensor to indicate a tension level in the seat restraint system when the at least one spring is deflected.
