5.1. During the meeting, for all discussions & decisions, the document CRS-42-03e (GRSP-54-36e) was updated for a version available under CRS-42-04e. The following points have been discussed :

• We need to precise retractor definition
• The size of the dummy to be used for lateral impact
• Revision of the chapters : 2.3.2 ; 2.17.2 ; 2.5.2 and 6.1.1 concerning the Universal vehicle Booster seat position
• Lower limit for authorized booster seat size range
• Chapter 6.3.2.2.2 only with one fixture for booster seat and booster cushion
• Rephrase 6.3.2.1 for shoulder height (measured only for harness system)
• Modified Annex 18 – Figure 2 to clarify the measurement of the Shh dimension.
• Question from CLEPA: is the technical regulation could clarify the delimitation of the responsibility between automakers and CRS manufacturers concerning the lateral protection of occupants above a certain stature.

Farid BENDJELLAL (BRITAX) explained that the drawing of the measuring device is incorrect. The drawing shows the shoulder height being measured to the centre of the cylinder, but it should be the top of the cylinder. he showed that a new drawing had already been implemented in an earlier draft of Phase 2 presented to GRSP (GRSP-56-09), but it had been omitted from recent drafts.

The new drawing was added to the consolidated amendments document that we were working on during the meeting and is included in our amendment of Phase 1. Erik SALTERS (DOREL) will send a new version of this drawing with better resolution.

29. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced: (i) the status report of the progress of his group (GRSP-55-34-Rev.1) and (ii) the latest update of the draft 01 series of amendments to UN Regulation No. 129 that incorporates provisions for booster seats (GRSP-55-08, superseding ECE/TRANS/WP.29/GRSP/2014/7). 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. GRSP agreed to refer GRSP-55-08 back to the IWG and to resume consideration of this agenda item at its December 2014 session on the basis of an updated proposal submitted by the IWG on ECRS.

30. The expert from France, Chair of the IWG on Enhanced Child Restraint Systems (ECRS), introduced the status report of the progress of his group (GRSP-54-35). He also introduced the draft 01 series of amendments to UN Regulation No. 129 (ECE/TRANS/WP.29/GRSP/2013/23) and GRSP-54-24 amending it. He explained that the proposal would cover Phase 2 of the UN Regulation, introducing provisions for non-integral CRS (“Universal Booster” or “Specific to vehicle Booster”). The expert from Germany expressed reservation to the proposal to discuss within the IWG the use of the Q10 dummy (proposed by the IWG for monitoring purpose only) for ensuring a safer level for children of different ages and heights. Moreover, he proposed modifying transitional provisions to allow CRS type approvals according to both UN Regulations Nos. 44 and 129. GRSP agreed to refer GRSP-54-36 to the IWG, incorporating all the changes to ECE/TRANS/WP.29/GRSP/2013/23 agreed during the session and awaiting a revised official proposal at its May 2014 session. GRSP also considered ECE/TRANS/WP.29/GRSP/2013/21 concerning the configuration of CRS combining a base attached with ISOFIX anchorages to the vehicle and a shell installed on it. GRSP adopted ECE/TRANS/WP.29/GRSP/2013/21 amended (as reproduced in ECE/TRANS/WP.29/2014/33) and requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their March 2014 sessions as draft Supplement 3 to the UN Regulation. GRSP also recommended experts to provide, by the May 2014 session, a draft brochure text as part of coordinated information campaign on UN Regulation No. 129.

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.
