A new injury risk criterion for restrained car occupants based on the collision response of the vehicle is presented. It is proposed that the total risk to a restrained occupant is due to the specific power of the impact and the intrusion/collapse of the occupant compartment. Risk functions for AIS2+ and AIS3+ injuries and for fatalities are validated using real world data.
