BioRID-II
- Standard ATD ARA-001
Humanetics BioRID-II was designed to promote the development of more effective head and neck protection during rear impact collisions. Prior dummy models indicated a severe lack of biofidelity, and so the BioRID was engineered to demonstrate a more natural neck movement consistent with whiplash from rear impact force.
The BioRID-II has been validated against low-speed volunteer data. It was developed by Chalmers University and Denton ATD (now part of Humanetics) and is produced by Humanetics.
User and certification instructions for the BioRID-II are available in United Nations Mutual Resolution No. 1 - Addendum 1 - Specifications for the Construction, Preparation and Certification of the 50th percentile male Biofidelic Rear Impact (BioRID-II UN) anthropomorphic test device.

Key Features
- Head: Modified Hybrid III. Chin modified to clear cervical vertebrae. Allows mounting leveling tool
- Neck, Thorax, and Abdomen: The BioRID-II’s distinguishing feature is its vertebral column, which consists of 24 separate vertebrae: five lumbar, 12 thoracic, and seven cervical. Washers, urethane bumpers, and muscle-simulating springs provide biofidelic performance. The vertebral column is installed inside a silicone jacket featuring pin linkages to the vertebrae and a water filled bladder in the abdominal region.
- Pelvis: The Sacrum-to-L5 Interface Plate mates the spine assembly to the modified Hybrid III pelvis, which features a lower cut iliac and larger leg opening.
- Legs and Arms: The legs and arms of the dummy are standard Hybrid III 50th, with the option to include any of the sensors available for these appendages. Humanetics has developed a modified upper leg to accommodate a DTS G5 unit for an iDummy version of the BioRID-II, which is also available.
