Abstract and keywords

Chest deflection could not be correlated with thoracic injury risk in past accident reconstructions with Q3 and Q6 dummies. The tendency of the diagonal belt to slide towards the neck was cited as one possible explanation. In this study, two issues were investigated: 1) Kinematics: diagonal belt sliding was assessed in sled simulations with a 6 YO human model and a Q6 model. Sliding was more pronounced with the Q6 than with the human model. 2) Chest response: the chest of a physical Q6 was loaded with a belt in various locations. The Q6 upper ribcage was found to be much softer than the chest deflection sensor region which was not observed in simulations with the human model. The deflection sensor also largely underestimated the deflection when the belt loading was away from it.

Combined, these results suggest that dummy changes may be required to reduce the amount of belt sliding and that an upper deflection sensor in the dummy could help assess thoracic loading of the Q6 dummy.
