22. The expert from CLEPA introduced a revised proposal (ECE/TRANS/WP.29/GRSP/2012/20) proposing to increase the strap acceleration to 3 g to prevent the locking phenomena during the buckling up of the safety-belts. GRSP finally adopted ECE/TRANS/WP.29/GRSP/2012/20, including a correction to Annex 13 to the UN Regulation, as reproduced by Annex IV to this report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2012/20 as amended to WP.29 and AC.1, for consideration and vote at their June 2013 sessions as draft Supplement 4 to the 06 series of amendments to UN Regulation No. 16.

23. The expert from OICA introduced GRSP-52-06 proposing an update of the air-bag labelling provisions into UN Regulation No. 16. The proposal received some comments such as those by the expert from Sweden (GRSP-52-14) proposing to align UN Regulation No. 16 completely with the provisions recently introduced into UN Regulation No. 94 (frontal collision) on this subject. Other experts suggested coming back to the preceding proposal (GRSP-51-14) referring to the paragraph numbers of UN Regulation No. 94 instead. GRSP agreed to resume discussion at its May 2013 session.

24. The expert from EC introduced GRSP-52-26, aimed at aligning the French version of paragraph 7.6.2.2. to the English one. GRSP adopted GRSP-52-26 as reproduced in Annex IV to this report and requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their June 2013 sessions as draft Corrigendum 1 to Revision 7 to the UN Regulation.

25. GRSP noted ECE/TRANS/WP.29/GRSP/2012/25, aimed at simplifying transitional provisions to the UN Regulation. However, GRSP preferred to defer discussion on this subject at its further session, awaiting further comments and the outcome of the activities of the WP.29 informal working group on the International World Vehicle Type Approval (IWVTA).

22. The expert from Sweden introduced ECE/TRANS/WP.29/GRSP/2013/8 harmonizing UN Regulation No. 16 with UN Regulation No. 94 concerning the warning label provisions on risks of installing a rear-facing CRS in a seating position equipped with air bag. The expert from OICA introduced ECE/TRANS/WP.29/GRSP/2013/13, proposing an alternative solution.

23. Finally, GRSP was more in favour of a proposal fully aligning the two above-mentioned UN Regulations and adopted ECE/TRANS/WP.29/GRSP/2013/8 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 2013 sessions as draft Supplement 5 to the 06 series of amendments to the UN Regulation.
