The expert from OICA gave a presentation (GRSP-55-35) on a possible child restraint fixture, covering booster seats for children older than 4 years.

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.
