Abstract: This paper analyzes the distribution of injured occupants in side impact collisions of light truck
vehicles to passenger cars in the real world. The injury levels were divided into MAIS 0-7 injured occupants
and MAIS 3+ injured occupants. The injury distribution of five main seriously injured body regions (including
head/face/neck, chest, pelvis, upper extremity and lower extremity) was investigated at delta velocity before
and after crash, using the delta velocity of struck and striking vehicles as the variable, according to 1.36 million
weighted crash compatibility cases extracted from the US National Automotive Sampling System (NASS) /
Crashworthiness Data System (CDS) database. The results show that the delta velocity of striking vehicle is
larger than that of the struck vehicle, and the occupant injured risk ratio is lower than that of the struck vehicle.
Therefore, avoiding the pelvis injury of drivers and passengers can reduce the risk of total occupants involved in
the collisions in consideration of crash compatibility.

Key words: vehicle safety, crash compatibility, front-to-side impact, passenger injury, injured body region
