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.

Abstract: A seat belt tension sensor assembly is adapted to be secured to the seat belt assembly of a vehicle. The assembly includes a housing for a seat belt anchor adapted for movement relative to the housing into an overload position where a portion of the anchor is abutted against a portion of the housing to limit and arrest the movement of the anchor relative to the housing and transfer the load from the anchor to the housing and then to an interior structure of the vehicle. In one embodiment, the housing forms a collar and the anchor includes an interior wall defining an aperture through which the collar extends when the anchor is mounted to the housing. Movement of the anchor relative to the housing is limited as a result of the contact between the interior anchor wall and the collar.

Abstract: A pressure sensor for sensing a pressure level of a pressurized medium. The pressure sensor includes a housing that has a high pressure side, a low pressure side and an aperture. A substrate is located in the aperture. The substrate has a pair of ends and a center portion. The center portion is brazed to the housing in the aperture. The center portion seals the high pressure side from the low pressure side. A pressure sensitive resistor is mounted to one end of the substrate. A reference resistor is mounted to another end of the substrate. A circuit line is located on the substrate. The circuit line is connected between the pressure sensitive resistor and the reference resistor.
