Abstract
A tension sensing assembly for a seat restraint system in a vehicle includes a housing for operative connection to vehicle structure and at least one spring disposed in the housing. The tension sensing assembly also 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 movable mechanism at least partially disposed in the housing and cooperable with belt webbing of the seat restraint system and the at least one spring to move the at least one magnet relative to the Hall effect sensor to change an output of the Hall effect sensor to indicate a first tension level and a second tension level in the seat restraint system when the at least one spring is deflected.
