Background presentation on the draft amendment to the GTR on head restraints. The amendment concerns changes to head restraint height measurement, use of the BioRID test dummy, and improvements to the overall text.
5. The expert from Germany, on behalf of the Chair of the Informal Working Group (IWG) on the UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, made a presentation (GRSP-58-18) on the Group’s progress. He clarified that the IWG intends to proceed with a more empirical approach on the correlation between Post Mortem Human Subjects (PMHS) and Biomechanical Rear Impact Dummy (BioRID). The results would be submitted as a subsequent amendment proposal on injury criteria (perhaps for adoption) at the May 2016 session of GRSP. He also introduced draft UN GTR Phase 2 (ECE/TRANS/WP.29/GRSP/2015/34 superseding ECE/TRANS/WP.29/GRSP/2013/24).
6. GRSP, in principle, agreed to change the height requirements of head restraints in ECE/TRANS/WP.29/GRSP/2015/34 to take into account ECE/TRANS/WP.29/GRSP/2013/17.
8. GRSP finally agreed to refer GRSP-58-26 back to the IWG, to incorporate all the comments from ECE/TRANS/WP.29/GRSP/2015/34, and resume discussion on this subject at its May 2016 session.

6. The expert from the United Kingdom, on behalf of the Chair of the Informal Working Group (IWG) on the UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, clarified that the IWG was following a more empirical approach to determine biomechanical criteria and that alternative methodologies were under study. He reported that the IWG expected to finalize proposals for the December 2016 session of GRSP on UN GTR No. 7 and on Addendum 1 to Mutual Resolution No. 1 (M.R.1) to incorporate Bio Rear Impact Dummy (BioRID) specifications. He concluded that an extension of the mandate of the IWG until March 2017 was needed to complete the final proposals and that AC.3 endorsed this request at its March 2016 session.
4. The expert from the United Kingdom, on behalf of the Chair of the Informal Working Group (IWG) on the UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, clarified that the IWG had suspended its activity because of a lack of results on biomechanical criteria. He added that the Chair’s intention was to resume the activity of the IWG and that he would contact the group’s members. He concluded that the Chair of the IWG would inform GRSP at its December 2017 session on the follow-up of activities of the IWG. The Chair of GRSP, on behalf of the expert of the United States of America, informed GRSP that the National Highway Traffic Administration (NHTSA) could possibly re-start correlation testing between dummy and the Post Mortem Human Subjects (PHMS). He volunteered to update GRSP about the plan of NHTSA on this subject at the December 2017 session.
4. The expert from the United Kingdom, on behalf of the Chair of the Informal Working Group (IWG) on UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, informed GRSP that for the time being the IWG had not yet decided when to resume its activity. He added that further information would be provided at the May 2018 session of GRSP.
4. The expert from the United Kingdom, on behalf of the Chair of the Informal Working Group (IWG) on UN Global Technical Regulation (UN GTR) No. 7 – Phase 2, informed GRSP that the IWG had not made progress in its activities and that no new information for the future development of the UN GTR to report. The expert from the United States of America informed GRSP that the Vehicle Research Testing Center of the National Highway Traffic Safety Administration (NHTSA) will resume and finalize its testing activity on the injury criteria by the end of 2018.
