"Low mass" sensor monitors forces in seat belts and other restraining harnesses. The sensor uses a "three bar" system, which minimizes errors caused by belt thickness effects. The low wrap angles used with this concept create minimum webbing disturbance, reduce the forces in the sensor, and permit large reductions in sensor weight. Low sensor weight is important for crash testing applications where the sensor undergoes large deceleration forces.
