21. The expert from the United Kingdom introduced ECE/TRANS/WP.29/GRSP/2012/3 aimed at introducing requirements to permit the effective upper belt anchorages of M2 and M3 vehicles to be adjusted below the minimum height required by the Regulation. GRSP noted that the proposal did not address any child restraint system (CRS) type approved according to UN Regulation No. 44. Accordingly, the expert from Germany suggested resuming discussion on the issue of CRS in buses at the next GRSP session. GRSP, finally adopted ECE/TRANS/WP.29/GRSP/2012/3, as amended by Annex III to this report. The secretariat was requested to submit the proposal to WP.29 and AC.1, for consideration and vote at their November 2012 sessions as draft Supplement 5 to the 07 series of amendments.

22. GRSP considered ECE/TRANS/WP.29/GRSP/2012/4 tabled by the experts from Belgium and Germany to solve errors concerning the anchorage angles (α1 and α2) and GRSP-51-08, tabled by the expert from OICA, to solve an error in the requirements of front seats of vehicle of category M1. GRSP adopted ECE/TRANS/WP.29/GRSP/2012/4 not amended and GRSP-51-08, as reproduced in Annex III to this report. The secretariat was requested to submit both proposals to WP.29 and AC.1, for consideration and vote at their November 2012 sessions as part of (see para. 21 of this report) draft Supplement 5 to the 07 series of amendments.
