28. GRSP considered ECE/TRANS/WP.29/GRSP/2012/5 tabled by the expert from Spain to prevent unintentional disengaging of ISOFIX child restraint systems from their anchorages. The proposal received some comments and proposals to change from GRSP experts (GRSP-51-15 and GRSP-51-27). Moreover, GRSP considered GRSP-51-36-Rev.1 superseding GRSP-51-15, GRSP-51-27 and ECE/TRANS/WP.29/GRSP/2012/5. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2012/5, as amended by Annex IV 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 6 to the 04 series of amendments.

29. The expert from the Netherlands introduced GRSP-51-31, superseding ECE/TRANS/WP.29/GRSP/2012/6, to solve some interpretation issues on the position of the lap belt during the dynamic test. The expert from UK suggested introducing a diagram into the proposal to definitively prevent misinterpretation. GRSP agreed to resume consideration on this matter at its December 2012 session awaiting a new document prepared by the expert from the Netherlands. In the same time the secretariat was requested to distribute GRSP-51-31 with an official symbol.
