✦ Synopsis

To

detect localized facial forces in laboratory car crash conditions, a load sensing face (LSF) was developed. Piezoelectric sensors provide pressure time histories. Design properties and characteristics of the LSF are described, as well as the sensor technique used. Sled tests with a LSF equipped dummy are presented. The purpose was to evaluate the efficiency of the method in registering facial impact magnitude and location with different restraint and seat position combinations. The LSF was also used in drop testing of steering wheels. Various impact velocities and impact points as well as the reapeatability were studied.
