N2  - The head protection with cyclist helmets in impacts against the A-pillar was investigated from experiments and finite element (FE) analyses. In the A-pillar impact tests at 35 km/h, the HIC was above the injury acceptance level even with helmet. The FE simulations of the headform impacts indicated that the helmet liner deformed locally, whereas the A-pillar deformation was small. In the FE analysis of a human head model with a helmet, the skull fracture did not occur but the brain strain was large. From a simple model of the head acceleration, the helmet liner characteristics has a little effect on the HIC at high velocity impacts.<p /> <p>Language: ja</p>
