Based on 130 medically and technically evaluated single-case analyses of real accidents involving child car-occupants, the importance of supposed major influencing parameters on trauma, such as impact direction, seating position as well as age, have been investigated. For the comparison of groups and as a measure of the dynamic load to the vehicle during the crash phase, the vector of resultant speed changing of the centre of gravity of car is calculated. For the valuation of the trauma, costs arising as injury sequence - assessed separately for children and other people - are applied under consideration of injury frequency and average of groups to draw comparisons. For improvement measures, the injury causes are analysed by their costs. Finally the use-value and - as an example - the use/cost-value for restraint devices used by children, and for types of restraint-system disfunctions are calculated in line of order with their costs as sequence of their suffered injuries.
