The CRABI (Child Restraint and Airbag Interaction) child ATDs were developed to evaluate small child restraint systems in automotive crash environments, in all directions of impact, with or without air bag interaction. Basic anthropometry for this important test device was taken from the University of Michigan Transportation Research Institute Report 85-23. Weight distribution and scaling methods for the infant were approved by the Society of Automotive Engineers' (SAE) Infant Dummy Task Group.
The Hybrid Ill-like neck and lumbar spine are laterally notched to reduce lateral stiffness. The shoulders have ample support for durability and human-like performance in areas where seatbelt webbing may be placed. In addition, rubber elements are used in each joint to improve biofidelity and to give CRABI infant-like range of motion.
The CRABI ATDs are designed in three sizes; 6MO, 12MO, 18MO.
