The findings in this paper should be regarded as preliminary; this is an initial effort by the UCLA Collision Research Projects to correlate experimental findings with observations of comparable accidental exposures. 1. In both the accidental and the experimental collisions, the adverse performance of the steering assembly was identical. The forward end of the steering column is anchored to the frame near the front-end. During head-on impacts, the collapsing front-end forces the rigid steering column and shaft axially rearward into the motorist compartment; the column and wheel are thrust towards the drive even before he is involuntarily pitched forward. Dummies and humans alike received tremendous blows to their head and chests by the steering columns. This design deficiency for the automobile was experimentally identified and reported in publication U.C.L.A. in the early '50's; it continues to be one of the principal causes of motorist injuries and deaths. 2. Correlation for occupant-to-car interior impacts was good both with respect to the experimental and the accidental collisions. The injury patterns inferred for the dummies corresponded closely with the actual injuries sustained by the human accident victims. Inferred injuries for the dummy head and neck are difficult to interpret. Only by considering comparable accidental exposures can a level of dummy head acceleration be identified as being a reasonable representation of the value accompanying concussion. Experimental findings indicate that the driver of the convertible sustained a head blow of about 50G; this was diagnosed as concussion. 3. Certain types of recurring injury patterns for the head-on collision victims appear because compartment design has not improved significantly during the past ten years. Regrettably, there are glaring examples of regressing to more hazardous passenger compartments for no better reason than to create the appearance of a "sharp" interior design. 4. Seat belts would reduce lower extremity injuries and thoracic injuries. However, the steering column being thrust towards the driver will still cause compressional chest injuries; amplification of driver facial injuries, as well as damage to the cervical spine may occur. A three-point belt, the shoulder harness-lap combination restraint, minimizes these injuries. 5. The information and experience derived from the analysis of experimental collisions is of significant benefit in ascertaining the kinematics of and dynamics of injury production to motorists involved in actual similar collision configurations
