Samenvatting
In this study, the effectiveness of rear lap and diagonal seat belts at limiting injuries during car collisions is estimated to be 40%. The nature, severity and frequency of injuries to belted and unbelted outboard rear seat passengers is described. The mechanisms and sources of injury are prioritised and discussed. It is shown that population differences, varying kinematics and restraint characteristics all combine to produce somewhat different levels of use and effectiveness for rear occupants in comparison to those in the front.
