Working draft of the phase 2 revisions to the global technical regulation on head restraints provided to the GRSP at its December 2013 session for informational purposes only.
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.
4. The expert from Japan, whose country was the technical sponsor of the UN Global Technical Regulation (UN GTR) No. 7 Phase 2, informed GRSP about the outcome of the last meeting (GRSP-54-30), held on 10-11 September 2013 in (Gothenburg), Sweden, of the informal working group (IWG) developing the draft UN GTR. The expert from Germany, made a presentation (GRSP-54-28) of the workshop held in Bergisch Gladbach (16 July 2013), Germany, aimed at defining a procedure for the test position of the Biofidelic Rear Impact Dummy (BioRID II). He added that as a result of the workshop, experts agreed that the use of the Head Restraint Measuring Device (HRMD) was no longer needed for static assessment and BioRID positioning. He concluded that test procedures and injury criteria would likely be finalized in the next meeting of the IWG scheduled for 4-6 February 2014 in Brussels. The expert from the United Kingdom introduced, for information, the latest stage of the draft UN GTR (ECE/TRANS/WP.29/GRSP/2013/24) and a draft Addendum 1 (GRSP-54-05) to the Mutual Resolution No. 1 (M.R.1). He explained that a revised official proposal of UN GTR would be submitted by the IWG at the May 2014 session of GRSP as well as a final draft addendum to M.R.1.
