10. GRSP resumed discussion on ECE/TRANS/WP.29/GRSP/2021/20, tabled by the expert from Spain, which provides updates of drawings of fixtures ISO/B2 and B3 (for assessing the external dimensions of an Enhanced Child Restraint System (ECRS)) for booster seats volumes to allow the possibility of a support leg. The expert from CLEPA provided more evidence from impact tests and simulations to justify the proposal (GRSP-72-36 and item 10, para. 28).

11. GRSP adopted ECE/TRANS/WP.29/GRSP/2021/20, amended by annex III to the session report. The secretariat was requested to submit the proposal as draft Supplement 4 to the 08 series of UN Regulation No. 16 (Safety-belts) for consideration and vote at the June 2023 sessions of WP.29 and AC.1.

12. GRSP resumed discussion on ECE/TRANS/WP.29/GRSP/2021/25 (UN Regulation No.16), tabled by the expert from CLEPA to improve the compatibility between the support leg volume and the fixtures to assess the volume of an ECRS. GRSP noted the justifications for this proposal in GRSP-72-36.

13. GRSP adopted ECE/TRANS/WP.29/GRSP/2021/25, not amended. The secretariat was requested to submit the proposal as part of (see paragraph 11 above) draft Supplement 4 to the 08 series of UN Regulation No. 16 (Safety-belts) for consideration and vote at the June 2023 sessions of WP.29 and AC.1.

Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2021/26 as amended by annex V to the session report. The secretariat was requested to submit the proposal as part of (see paragraph 27 above) draft Supplement 9 to the 03 series of UN Regulation No. 129 (ECRS) for consideration and vote at the June 2023 sessions of WP.29 and AC.1.

6. | UN Regulation No. 16 (Safety-belts)

10. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2021/25 in a presentation (GRSP-70-18), amending the existing support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for assessing the external dimensions of an Enhanced Child Restraint System. GRSP agreed to resume discussion on a revised version of ECE/TRANS/WP.29/GRSP/2021/25 (UN Regulation No.16), at its May 2022 session requesting more evidence in real crash.
