Abstract
A seat belt tension sensor for measuring the amount of tension in a vehicle seat belt. The seat belt tension sensor has a housing and an anchor plate. A lever is mounted in the housing. The lever holds a magnet. A sensor is mounted to the housing. The sensor generates an electrical signal in response to relative movement between the magnet and the sensor. The electrical signal changes in proportion to the amount of tension on the seat belt. A spring is mounted in association with the housing and the anchor plate. The spring biases the housing from the anchor plate.
