CRABI
Description
The CRABI impact dummy is designed to evaluate small child restraint systems in crash testing, simulating the weight and dimensions of infants aged 6, 12, and 18 months [1].
WebSAT uses the ATD recorded with a loaded test to select available calculations and applicable reference values.
