The MAMA-2B (Maternal Anthropomorphic Measurement Apparatus, version 2B), a small female Hybrid III pregnant dummy used to study the safety of a fetus and effects of seat belt and airbags has been evaluated and enhanced. Two IR-TRACCs (Infra-Red Telescoping Rod for the Assessment of Chest Compression) have been added to measure the chest deflection. A potentiometer was added to measure the IR-TRACC rotation. Two accelerometers have also been added for the chest Viscous Criterion (V*C) calculation. The water-filled abdomen bladder was evaluated. The center of gravity of the slouch posture of the dummy was estimated. Certification tests were conducted and the corridors have been proposed.
