16. The expert from CLEPA introduced GRSP-56-10 (superseding ECE/TRANS/WP.29/GRSP/2014/27) aimed at clarifying the provisions for dynamic testing of rear seat system and advanced restraint system approval. The expert from France stressed the need to update the test provisions to verify displacement of rear occupants wearing safety-belts equipped with load limiters. He informed GRSP that the New Car Assessment Programme was defining similar provisions by using the fifth percentile female dummy. GRSP agreed to resume discussion on this subject at its May 2015 session and requested the secretariat to distribute GRSP-56-10 with an official symbol.

17. The expert from OICA introduced GRSP-56-14, complemented by GRSP-56-16 reproducing a consolidated text of the amendments proposed [in document GRSP-56-14]. He explained that the proposal was needed to verify which seating positions would allow the installation of the universal booster child restraint system (CRS) proposed by the draft 01 series of amendments to the UN Regulation No. 129 (Enhanced Child Restraint Systems) (see para. 33 below). He clarified that the proposal was aimed at introducing physical [testing], computer simulation or any other means [acceptable to a type-approval authority] to assess [compliance with the child-restraint fixture installation requirements]. The expert from CLEPA introduced GRSP-56-35 to clarify the dimensions of ISOFIX anchorages of the proposed fixture. The expert from OICA argued that GRSP-56-35 could lead to misinterpretation since UN Regulation No. 16 is not dealing with ISOFIX anchorage provisions. The expert from EC noted that the required information on ISOFIX installation (see Annex 17, Appendix 3, tables 1-3 of the UN Regulation No. 16) could be misleading for consumers. The expert from France clarified that the introduction of booster cushion was aimed at improving comfort rather than safety and that the IWG designed provisions for a universal system of this type of CRS as per other CRS. GRSP agreed to refer GRSP-56-14, GRSP-56-16 and GRSP-56-35 to the IWG on CRS for further discussion and agreed to resume consideration on this subject at its May 2015 session.

18. GRSP noted GRSP-56-42 (for information only) tabled by the expert from Korea and aimed at introducing the mandatory fitting of safety-belt reminders also for rear seats. GRSP agreed to resume discussion on this subject at its May 2015 session and to keep ECE/TRANS/WP.29/GRSP/2012/25 in the agenda for possible discussion at its next sessions.
