29. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced a presentation (GRSP-57-22) to show the work progress of the IWG and the main content of draft 01 series of amendments incorporating provisions for booster seats (GRSP-57-20 and GRSP-57-21 superseding ECE/TRANS/WP.29/GRSP/2015/9). He added that for Phase II of the UN Regulation there were still some pending issues such as safety for children in cars on booster cushions without a backrest and geometric definition of the test fixture (gabarit) for booster seats with an integrated backrest. The expert from Germany suggested only the inclusion of booster cushions with backrests in UN Regulation No. 129, while provisions for other kind of boosters should remain for the time being in UN Regulation No. 44 pending a whole revision of this last UN Regulation. The expert from EC endorsed the work of the IWG and he proposed further promotion of the of i-size concept to allow the installation of three ECRS on the same row seat in larger family cars. GRSP agreed to resume discussion at its December 2015 session on this subject awaiting the outcome of the IWG and requested to distribute GRSP-57-20 with an official symbol.

33. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) a presentation to show the main content of the draft 01 series of amendments incorporating provisions for booster seats (GRSP-56-28), (ii) the draft proposal (GRSP-56-08 superseding ECE/TRANS/WP.29/GRSP/2014/28) and (iii) the consolidated version of the UN Regulation, incorporating the proposed amendments (GRSP-56-09). The expert from OICA proposed to reduce the height of the measuring device, to evaluate a universal booster cushion, from 910 mm to 830 mm. He explained that this last value would be less restrictive for vehicle design. The expert from EC informed GRSP that a research test report on child abdominal injuries would be published soon. Accordingly, he raised a study reservation to consider the above-mentioned outcome of research and to complete the assessment of GRSP-56-08. GRSP agreed to resume discussion at its May 2015 session to consider and adopt, as a whole, draft 01 series of amendments and the parallel amendments to UN Regulation No. 16 (see para. 17). Finally, the secretariat was requested to distribute GRSP-56-08 with an official symbol at the next GRSP session.
