Abstract
A kinematic analysis of the head-neck unit has been conducted in 37 simulated traffic accidents in order to investigate correlations between neck response and injuries. Belted fresh human cadavers in the age range 18 to 74 years have been used as front and rear-seat passengers. The analyzed data included 23 frontal collisions, impact velocity 30 km/h, 50 km/h and 60 km/h, barrier impact and 14 90 degree-car to car lateral collisions with near-side passengers (6 cases) as well as far-side rear-seat passengers with an in-board anchoring point for the shoulder belt (8 cases). The head bending angle depended on the type of the collision.
