Neck moment response characterization of restrained child occupant at standard test impact speed 24.4 km/h

The effects of bullet vehicle crash impact angle, child restraint system design and restraint harness slack at standard test side impact speed of 24.4 km/h (15 mph) on moments sustained at the neck by a three year old child is investigated. A statistical methodology employing the Design of Experimen...
