4. Report of the 5th session of GRSP (ECE-TRANS-WP29-GRSP-56e) from the Chairman :
The expert from France informed GRSP that, for the time being, the IWG does not have the resources to provide a corresponding Addendum to the M.R.1. to include drawings and specifications of the Q dummies, due to their number and complexity. He explained that the IWG likely would reallocate resources in the future to cover this issue. Finally, he asked for a one year extension of mandate of the IWG to develop Phase 3 of the UN Regulation (covering CRS using adult safety-belts to restrain children). The expert from Germany underlined that the initial purpose of the UN Regulation, to incorporate for better clarity all provisions concerning universal ISOFIX, had been compromised by covering a number of different CRS categories. Finally, GRSP agreed to seek the endorsement of WP.29 to extend the mandate of the IWG until December 2015. GRSP considered and adopted GRSP-56-31-Rev.1, to prevent installation of y-shaped straps on forward facing CRS, as reproduced in Annex V of this report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their March 2015 sessions, as draft Supplement 4 to the UN Regulation No. 129 (ECE/TRANS/WP.29/2015/43). The experts from CLEPA and CI introduced respectively GRSP-56-24 and GRSP-56-27, as a draft brochure for a coordinated information campaign on UN Regulation No. 129. The expert from Germany announced that a similar initiative would be published soon in his country. GRSP agreed to resume discussion on this subject on the basis of a possible common text agreed by interested parties. Chairman : Phase II cover up to 135cm for lateral impact. The issue concerning what to do from 135 cm up to 150 cm for booster cushions still remains. Lateral protection will not be mandatory over a stature of 135 cm, for universal R129 ECRS but still remains possible for specific to vehicle R129 ECRS. European Commission: Peter BROERTJES informed the working group that the EC is not fully satisfied with the current content of phase 2. EC highlights the fact that the Q dummies are not able to predict correctly child abdomen injury due to submarining with booster seats. The EC contracted TRL to conduct a study on that topic to potentially modify dummies, test setup or test conditions. This study should be terminated end of 2015. Even if such investigation has already been undertaken previously by other stakeholders without success, it will delay very probably the adoption of regulation 129 phase 2 at least by 6 months. Some clarifications to the original text have been brought concerning several aspects :
OICA : Can we have specific booster cushions below 125 cm?
The updated document is under CRS-49-03e Reiner NETT (TAKATA) : can a universal booster exist claiming a stature greater than 135 cm ? A list of items to be reviewed for phase II (CRS-49-05e) was drafted during the meeting by the group. A leader for each item was appointed.
Items to be review for phase III (CRS-49-05e) listed during the meeting by the group :
