Two manufacturers, Denton ATD and FTSS, currently produce the Hybrid III 5th percentile female dummy. In response to concerns raised by industry that differences in the anthropometry of the molded breasts between the two manufacturers may influence chest responses, Transport Canada conducted a comparative testing program. Thorax biofidelity tests were conducted to compare force-deflection characteristics; full-frontal, rigid-barrier tests were conducted at 40, 48 and 56 km/h to compare chest responses, and out-of-position chest on module static airbag deployment tests were conducted to compare peak chest deflections of the Denton and FTSS dummy jackets and of a prototype jacket without breasts. Differences in force-deflection characteristics were observed during biofidelity pendulum impacts of the two dummies, with much of the differences attributed to the different chest jackets.
