18. GRSP noted GRSP-50-05-Rev.1, tabled by the experts from Belgium and Germany to solve errors in the current text of the Regulation concerning the anchorage angles (α1 and α2) and the seating reference point (R-point). GRSP noted that the proposal had design implication and agreed to continue discussion at its May 2012 session. The secretariat was requested to distribute GRSP-50-05-Rev.1 with an official symbol.

19. The expert from Spain introduced a proposal (GRSP-50-17) to allow the installation of safety-belt anchorages whose effective upper anchorage point is changing to fit smaller occupants such as children transported on buses and coaches. The expert from Germany argued that such systems were already present on the market and some of these were introducing risks for occupants by assuming a dangerous configuration (GRSP-50-23). GRSP agreed to resume consideration on this subject at its May 2012 session, on the basis of a revised proposal jointly prepared by the experts from Germany, Netherlands and Spain. GRSP also agreed to keep GRSP-50-23 as a reference on the agenda of its next session.

20. The expert from France, Chair of the informal working group on Child Restraints Systems (CRS), introduced ECE/TRANS/WP.29/GRSP/2011/22 prepared by his group to align UN Regulation No. 14 with the provisions of draft Regulation on child restraint systems (CRS). GRSP adopted ECE/TRANS/WP.29/GRSP/2011/22, not amended. The secretariat was requested to submit it to WP.29 and AC.1, for consideration and vote at their June 2012 sessions for the time being as draft [Supplement 4 to the 07 series of amendments]. GRSP also agreed to recommend its adoption to WP.29 and AC.1 as a full package with the draft UN Regulation on CRS (ECE/TRANS/WP.29/GRSP/2011/21) and the corresponding amendment to UN Regulation No. 16 (ECE/TRANS/WP.29/GRSP/2011/23).
