9. The expert from Spain introduced GRSP ECE/TRANS/WP.29/GRSP/2021/20 in a presentation (GRSP-70-03), updating drawings of fixtures of booster seats to allow the seats to be designed in combination with a support leg as anti-rotational systems. The proposal caused concern with GRSP experts for the effects on UN Regulation No. 145 (ISOFIX anchorage systems, ISOFIX top tether anchorages and i-Size) and real-world crashes. GRSP agreed to resume discussion on a revised version of ECE/TRANS/WP.29/GRSP/2021/20 (UN Regulation No. 16), at its May 2022 session with more evidence of the crash situation in real vehicles, in side impact and offset configuration.
