5. Effective Head Mass at Impact
<IHRA/PS167>• Effective head mass varies significantly according to the impact conditions such as vehicle shape, stiffness, walking stance and so on.
• Average effective head mass Head mass≒ Adult head: 4.5 kg (Ref. IHRA/PS150, ISO/N354) Child head: 3.5 kg (Ref. IHRA/PS178, SAE973317)
<IHRA/PS178, SAE973317>* 3-Year Child Head Mass = 2.7 kg
* 6-Year Child Head Mass = 3.5 kg * 5th % Adult Female Head Mass = 3.6 kg
