Abstract
The invention is directed to a method for setting an occupant classification system threshold for a vehicle occupant detection system, the method comprising collecting occupant classification system data for a seat, the data being indicative of occupant weight, analyzing the data to determine where a separation exists between an occupant for which a restraint should be suppressed and an occupant for which the restraint should be deployed, and analyzing the data to determine a worst case child suppression weight and shape, which is based at least on where the separation exists. The worst case child suppression weight and shape define the occupant classification system threshold.

19. A device for calibrating an occupant classification system threshold for a vehicle occupant detection system, the device comprising:
-
a force application mechanism; a weight drop head having a worst case child suppression shape and being attached to the force application mechanism; and controls that move the weight drop head and activate the force application mechanism to apply a force to a vehicle seat that is representative of a worst case child suppression weight for that seat, wherein a pressure measurement device in the vehicle seat outputs a signal indicative of the applied force, the occupant classification system threshold being calibrated based on the signal. - View Dependent Claims (20, 21, 22, 23)

24. A device for setting, calibrating, and verifying an occupant classification system threshold for a vehicle occupant detection system, the device comprising:
-
a force applicator; a weight drop head having a worst case child suppression shape and being attached to the force application mechanism; a pressure measurement device configured to measure a force applied by the force applicator and weight drop head; and controls configured to activate the force applicator to apply a force to the pressure measurement device, wherein, when a force is applied to the pressure measurement device by the force applicator and weight drop head, the pressure measurement device outputs a signal indicative of the applied force for use in setting, calibrating, and verifying the occupant classification system threshold. - View Dependent Claims (25, 26, 27, 28)
