3. The expert from Spain informed GRSG that the Working Party on Passive Safety (GRSP) would consider, at its December 2023 session, a proposal (ECE/TRANS/WP.29/GRSP/2023/30) of revised terms of references (ToRs) for IWG on Safer Transport of Children in Buses and Coaches (IWG-STCBC). The expert from Germany, on behalf of the Chair of IWG-STCBC, introduced a presentation (GRSG-126-05) on the work progress. He confirmed that the new UN Regulation prepared by IWG-STCBC would deal with existing systems used in passenger cars, favouring built-in Child Restraint Systems (CRS) and Enhanced CRS that were type approved according to UN Regulation No. 129 (ECRS). In the meantime, he confirmed that the second phase of the UN Regulation would entail CRS in combination with two-point safety belts. He clarified that separate components on CRS for installation would not be allowed, nor combination of two-point belts and top tether or support leg. Finally, he explained the ongoing and upcoming IWG activities on test procedures. GRSG agreed to resume consideration on this subject at its April 2024 session and endorsed the revised IWG ToR (ECE/TRANS/WP.29/GRSP/2023/30) without amendments. The GRSG Chair encouraged GRSG experts to liaise with GRSP to backup this activity.
