WebbTheoretical Head Impact Velocity (THIV) has been developed to assess damage on passengers when crashing into a system. Passengers are considered to be a freely moving object (head) that when the car changes speed upon impact a system continues until it hits a surface in the vehicle's interior. Webb– Theoretical Head Impact Velocity (THIV) – Post-Head Impact Deceleration (PHD) EN 1317-5 2007 In the 2010 version, the PHD has been removed because, as a result of exentive empirical evidence, experts judged it to be unreliable as a parameter.
