27. GRSP adopted ECE/TRANS/WP.29/GRSP/2011/25 and ECE/TRANS/WP.29/GRSP/2011/31, both not amended, ECE/TRANS/WP.29/GRSP/2011/32 and ECE/TRANS/WP.29/GRSP/2011/28, both as amended by Annex IV [of the session report], and GRSP-50-14 as reproduced in Annex IV [of the session report]. The secretariat was requested to submit all the proposals to WP.29 and AC.1, for consideration and vote at their June 2012 session as draft Supplement 5 to the 04 series of amendments to UN Regulation No. 44.

28. GRSP did not support ECE/TRANS/WP.29/GRSP/2011/26, that matched the corresponding proposal of amendments to UN Regulation No. 16 (see para. 22 above) and postponed discussions on ECE/TRANS/WP.29/GRSP/2011/27 awaiting a revised wording of paragraph 6.1.5. Finally, the expert from Spain withdrew ECE/TRANS/WP.29/GRSP/2011/29 and introduced GRSP-50-16, superseding ECE/TRANS/WP.29/GRSP/2011/30. The secretariat was requested to distribute GRSP-50-16 with an official symbol for consideration at its May 2012 session.

29. The expert from CLEPA introduced GRSP-50-08 on inflatable CRS, to provide information on this system sold in the European market and [his doubtful opinion on its compliance] with UN Regulation No. 44. He showed a video presentation (GRSP-50-25) on the risks (i.e. submarining of CRS occupants) introduced by the system. The expert from the Czech Republic argued (GRSP-50-21) that his administration had been granting successful type approvals to inflatable CRS since 2008. Accordingly, the expert from the Netherlands made a proposal (GRSP-50-33-Rev.1) to prevent different interpretations of the lap belt position during dynamic test of CRS secured by adult safety belts, such as inflatable CRS. GRSP agreed to resume consideration on this subject at its May 2012 session and requested the secretariat to distribute GRSP-50-33-Rev.1 with an official symbol.

30. The expert from CLEPA provided further information to GRSP (GRSP-50-09 and GRSP-50-25) on the so called belt guide device and test results of this system, as a followup of the May 2011 session of GRSP (see ECE/TRANS/WP.29/GRSP/49, para. 28). GRSP noted that the Hungarian administration granted a type approval to this device according to Regulation No. 44. However, it was also noted that the device was banned in several countries. The expert from Hungary informed GRSP that his administration had started an action to withdraw the approval but that it was incomplete due to a legal challenge by the manufacturer. The guidance provided in ECE/TRANS/WP.29/1059 (resolving interpretation issues and requirements for the Technical Services in the framework of the 1958 Agreement) was noted and GRSP agreed that it could offer clarity regarding the technical requirements associated with a particular UN Regulation to assist in disputes among technical services of Contracting Parties to the Agreement.

Concerning the belt guide device, GRSP agreed on the principle (GRSP-50-34) that a guide strap was meant as a part of CRS and therefore could not be individually approved as a CRS under UN Regulation No. 44. Moreover, GRSP expressed concerns on the safety of this device. Finally, GRSP agreed to continue discussion on this matter on the basis of information on possible actions taken by competent Type Approval Authority of Contracting Parties to the Agreement on this issue.

27. The expert from EC introduced ECE/TRANS/WP.29/GRSP/2019/28 aimed at clarifying the types of belt-guides and sitting devices that would not be allowed by means of an explanation in the scope of the UN Regulation. The expert from Poland argued that the proposal from EC was restrictive and requested a facts-based discussion on this proposal or a simple rejection in full. He introduced a presentation GRSP-66-19, showing that one of the devices in ECE/TRANS/WP.29/GRSP/2019/28 was fully compliant with UN Regulation No. 44 and safer compared to other type approved CRS. The expert from Spain introduced GRSP-66-30 which provided counter evidence that belt-guide devices would not comply to a number of relevant requirements of UN Regulation No. 44. The expert from Japan introduced a presentation (GRSP-66-38) showing the sled test conducted on Q dummies to check safety-belt penetration according to UN Regulation No 129 requirements. He concluded that the abdominal pressure on the belt-guide device was found to be rather high compared to CRS type approval according to UN Regulation No. 129, but that it satisfied the requirements of the UN Regulation.

28. Finally, the majority of GRSP experts, with the exception of the expert from Poland, adopted ECE/TRANS/WP.29/GRSP/2019/28, not amended. The secretariat was requested to submit the proposal as part of (see para. 26) Supplement 18 to the 04 series of amendments to UN Regulation No. 44, for consideration and vote at the June 2020 sessions of WP.29 and AC.1.
