European Enhanced Vehicle-safety Committee Questions and answers on pole side impact: - Frequency of pole side impact? Developing an Rare European Interior Headform Test Procedure - Severity of pole side impact? Very severe => therefore of importance T. Langner on behalf of - Injured body regions? EEVC WG 13 Mainly head and thorax, also spine for low severity - Impact 19 th speed? International Technical Conference Often higher but a speed aroundof 30 km/h seems reasonable onspeeds Enhanced Safety Vehicles - Direction of force (including severity)?
