ABSTRACT:
A seat belt tension sensor is attached to a seat belt assembly in a vehicle. The seat belt tensor sensor is secured to the vehicle by a bolt. The sensor includes a housing that is secured by the bolt. An anchor plate is mounted to the housing. The anchor plate has a hole for the bolt and an opening. A strain gage is secured to the housing and extends into the opening. The strain gage has an aperture. A spring is located between the anchor plate and the strain gage. An actuator support is located between the spring and the strain gage to actuate the strain gage. The actuator has a projection extending through the aperture that contacts the anchor plate. The projection prevents a shift in the output of the strain gage when the sensor is subjected to mechanical shock.
