Presentation on the results of investigations designed to measure quasi-static spine stiffnesses and performance of the BioRID II dummy.

In 2010 calibration tests without headrest （see document GTR7-06-06）, the waveform configurations of the 095G dummy were different from those of the 102G dummy and the 115G dummy. This presentation, updated from the GTR7-8 session, provides the results of investigations into this difference.

In 2010 calibration tests without headrest （see document GTR7-06-06）, the waveform configurations （phase shift） of the 095G dummy were different from those of the 102G dummy and the 115G dummy. This presentation provides the results of investigations into this difference.

Results of BioRID-II dummy calibration tests with headrest conducted using heavy and light probe weights to evaluate the repeatability and reproducibility of the dummy responses.

Presentation on the results of testing to compare the responses of the BioRID II with those of the Hybrid III when subjected to FMVSS 202a and Modified Annex 9 rear impact pulses using OEM vehicle seats.
