Tension sensing assembly

A dual level tension sensing assembly for a seat restraint system in a vehicle comprising:

• an anchor plate adapted to be connected to vehicle structure;
• a housing connected to said anchor plate;
• at least one spring disposed in said housing;
• at least one magnet disposed in said housing;
• a Hall effect sensor disposed in said housing and cooperable with said at least one magnet;
• and
• a movable mechanism disposed in said housing and cooperable with belt webbing of the seat restraint system and said 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 said at least one spring is deflected.

A seat restraint system for a vehicle comprising:

• a seat restraint webbing;
• an anchor plate adapted to be connected to vehicle structure;
• a housing connected to said anchor plate;
• a first spring disposed in said housing;
• a second spring disposed in said housing;
• at least one magnet disposed in said housing;
• a Hall effect sensor disposed in said housing and cooperable with said at least one magnet;
• and
• a movable mechanism disposed in said housing and cooperable with said seat restraint webbing of the seat restraint system and said first spring and said second 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 said first spring an said second spring are deflected.
