THE EFFECTS OF AUTOMOBILE INTERIOR DESIGN CHANGES ON INJURY RISK

Objectives of this study were to examine: the changes in injury source rankings associated with introduction of the major safety orientated component modifications; the effectiveness of the Energy Absorbing steering system; the influence of the head restraint on whiplash injury. Data pertaining to 1 and 2-car collisions involving American make automobiles manufactured between 1960 and 1973 were used in this study. These data were selected from the files of Calspan's Tri-Level Accident Study and Automobile Crash Injury Research Program. Major injury source were ranked in terms of potential injury hazard for pre- (1960-65) and post-standard vehicles (1968-73, with major safety modifications). The head restraint and EA system were examined by comparing the differences in injury incidence and severity between equipped and unequipped vehicles. Little change was recorded for injury source rankings between pre and post standards vehicles for injuries classified as minor. For serious injury, decreases in injury hazard associated with the instrument panel, wind-shield, and steering assembly were evident. For overall injury, the EA system was demonstrated effective in reducing injury risk for lap belted drivers, and relatively ineffective for unrestrained drivers. As far as individual injury types, results were similar for unrestrained and lap belted drivers. Recorded were decrease in injury risk of head injury and no influence on thorax injury risk. Some of the safety modifications have been effective in reducing occupant injury risk. The influence of the EA system on head and chest injury indicates the need for good injury data and detailed accident information for this type of analysis. /Author/
