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 that is mounted in the housing. The housing moves relative to the anchor plate. A magnet is affixed to the anchor plate. A sensor is mounted to the housing. The sensor generates an electrical signal in response to relative movement between the housing and the anchor plate. The electrical signal changes in proportion to the amount of tension on the seat belt. A spring is mounted between the housing and the anchor plate. The spring biases the housing from the anchor plate. An integral connector extends from the housing.
