Excerpts from session reports related to this document
GRSP \| Session 75 \| 27-31 May 2024		13. The expert from the Republic of Korea, Chair of the ad-hoc group on seat-belt reminders (SBR), introduced GRSP-75-12 to explain that were different interpretations to be solved on SBR activation when the safety-belts was unfastened. The expert from Spain argued that current provisions in the UN Regulation need changes. Furthermore, the expert from the Republic of Korea introduced ECE/TRANS/WP.29/GRSP/2024/2 to clarify the text of the UN Regulation. GRSP also noted ECE/TRANS/WP.29/GRSP/2024/6, tabled by the expert from Germany to clarify the buckle-opening test. GRSP endorsed in principle this last proposal. GRSP finally agreed to resume consideration on ECE/TRANS/WP.29/GRSP/2024/2, ECE/TRANS/WP.29/GRSP/2024/6 and ECE/TRANS/WP.29/GRSP/2023/32 (see ECE/TRANS/WP.29/GRSP/74, paragraph 19) at the December 2024 session of GRSP. The experts from Germany, Japan and the Republic of Korea were requested to adapt their respective proposals to the new adopted UN Regulations and to the 10 series of amendments to UN Regulation No. 16 (see paragraph 12 above).
