Abstract

The description of real-world lateral impacts presented here givesa distribution of injury severity by position occupied in relation to the crush area for 1189 occupants involved in car-to-car collisions.

The levels of risk incurrcd by front-seat occupants are examined in relation with the wearing of seatbelts and the ΔV of impacted vehicles.

We restate the method for evaluation of the "occupant-wall" velocity following detailed examination of real-world accidents.

This method was utilized on a sub-sample of 134 near-side occupants exposed to direct penetration of the impacted lateral wall.

We analyse the characteristics of the deformations observedo n the one hand, and the relationship between the parameters for impact severity and injury severity on the other.

An experiment carried out confirms the hypothesis that the residual deformation capacity of certain current production doors at the mornent of contact with the occupant cannot be ignored in the injury figures recorded in real-world lateral impacts.
