Description of Dummy Features
The shape and response of the Hybrid III Six-Year-Old Child (H-III6C) Dummy was scaled down from that of the Hybrid III 50th Percentile Male Dummy. However a number of additional features were then added to the H-III6C dummy to enhance its durability and utility for repeated use in evaluating risks to the out-of-position child in the airbag environment. Stronger steel ribs and rib stiffeners were included to improve the durability of the thorax. The performance of the dummy was enhanced to accommodate both the historically used potentiometer for measuring chest deflection and newly added accelerometers to the thoracic cavity. Within the thorax, the addition of rubber stops and additional clearance served to protect this instrumentation. The addition of upper and lower rib stops and a metal strip with recesses to hold each rib from pivoting about the sternum area permitted repeated measurements of the forward/aftward chest deflection characteristics. Modifications to the abdomen also provided additional clearance for travel of the chest deflection transducer arm, and control of dummy posture and flexion of the torso.
