10. The expert from Germany informed GRSP (GRSP-75-27) about a workshop held at the Federal Highway Research Institute (BASt) on 25 and 26 April 2024. He noted that the workshop aimed at a verification ECE/TRANS/WP.29/GRSP/2023/28 (introduced by the expert from OICA at the December 2023 session of GRSP), which allows occupants to use alternative seating positions only if this was not in conflict with any other UN Regulation. The expert from CLEPA noted that the workshop had not referred to child restraint systems nor how to secure children. He added that only adult dummies had been considered and questioned the alternative seating positions of children. The expert from Germany confirmed the relevance of children in this issue.. The expert from OICA introduced GRSP-75-13 (superseding ECE/TRANS/WP.29/GRSP/2023/28). The expert from France asked for a detailed justification, stating that reference point “HR” was confusing. GRSP agreed to resume consideration on a revised proposal tabled by the expert from OICA at its December 2024 session. GRSP requested its interested experts to liaise with the expert from OICA on feedback to improve GRSP-75-13.

12. The expert from OICA introduced a presentation (GRSP-74-20) to reintroduce a proposal (ECE/TRANS/WP.29/GRSP/2023/28, amended by GRSP-74-19) that allowed occupants to use alternative seating positions only if this was not in conflict with any other UN Regulation. The expert from Germany recommended the need to start studies and to reflect on this subject to introduce a proper amendment. The expert from France agreed. The expert from the Netherland stated that an adoption of the proposal was premature. He added that the topic was relevant and suggested focusing on broader perspectives (e.g. autonomous vehicles and new interior layouts). Finally, GRSP agreed to establish a group of interested experts led by Germany and to organize a workshop (managed by OICA). Experts from contracting parties were invited to join the discussion and to also table concerns.
