A tension sensing assembly for a seat restraint system in a vehicle includes a housing and a movable mechanism disposed in the housing. The tension sensing assembly also includes at least one spring disposed in the housing and cooperable with the movable mechanism. The tension sensing assembly includes at least one magnet disposed in the housing and a Hall effect sensor disposed in the housing and cooperable with the at least one magnet. The tension sensing assembly further includes a cable extending through the housing and cooperable with the movable mechanism to move the movable mechanism to deflect the at least one spring. The movable mechanism moves the at least one magnet relative to 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.
