Abstract

This paper documents seven car/car lateral collisions with belted farside rear seat occupants. The test subjects - cadavers and US SIDs - were restrained with a 3-point belt which had an inboard upper anchoring point for the shoulder belt. The collision velocity was 50 km/h. In the cadaver tests, the maximum resultant acceleration, an average of 18 G, was located at the clivus. In the US SID a maximum of 22 G occurred at the C.G. Average shoulder belt forces in the cadavers of 1,6 KN were measured compared to 2,5 KN in the US SID.

Through an analysis of the high speed films, lateral head-neck bending angles of 40 to 65 degrees for the cadavers were investigated. The calculated angular velocities were between 13 and 38 rad/s and angular accelerations between 350 and 644 rad/s 2.

No head, thorax or pelvic injuries were observed. Belt-induced minor injuries at the skin on the neck, neck muscles and cervical spine were observed with a MAIS 1.

The calculated values of the angular velocities and angular acceleration are in agreement with the observed minor injuries in the neck region.
