Updated presentation from the previous informal group meeting (GTR7-08) of December 2011 on the development of new procedures to ensure effectiveness of headrest protection for taller occupants (e.g., when headrest set at maximum height).

Comparison of FMVSS 202a, GTR 7 (Annex 1) and Netherlands-proposed height measurement procedure (per the December 2011 presentation).

Overview of Japanese research and conclusions regarding the reduction of minor neck injuries during rear-end impacts.

Expanded review of J-MLIT,JASIC, and JARI research into the Inter-Vertebral Neck Injury Criterion (IV-NIC) as part of collobarative investigations with the USA.

Expanded preliminary findings on post-mortem human subject injury risk curves and potential injury assessment reference values for rear-impact protection testing.

Overview of factors involved with precision of HRMD-backset measurements.

OICA/CLEPA presentation supporting the use a of head-restraint measuring device (HRMD) to enhance GTR 7 test procedures.

Draft report on the activities of the technical evaluation group developing certification procedures for the BioRID II dummy.

Extensive presentation on the results of investigations into BioRID seat test responses compared against certification results, in particular with regard to repeatability and reproducibility.

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.
