Abstract
A tension sensing assembly for a seat restraint system in a vehicle is provided. The tension sensing assembly comprises an anchor, a movable mechanism configured to be secured to a portion of a buckle, at least one magnet coupled to the movable mechanism, a Hall effect sensor coupled to the anchor, at least one tension spring secured to the anchor at a first end and the movable mechanism at a second end. The movable mechanism moves the at least one magnet relative to the Hall effect sensor to induce an output from the Hall effect sensor. The output indicates a tension level being applied to the tension sensing assembly.
