11. The expert from Japan presented proposal ECE/TRANS/WP.29/GRSP/2024/23 to amend the newly created UN Regulation No. 173, in order to limit the slack of the buckle belt. The expert from OICA presented informal document GRSP-76-32, amending this proposal to include transitional provisions. Following a discussion of this informal document, the expert from OICA submitted a revised proposal (informal document GRSP-76-32-Rev.1). GRSP adopted ECE/TRANS/WP.29/GRSP/2024/23 as amended by informal document GRSP-76-32-Rev.1 (see annex IV, section A) and requested the secretariat to submit them as a proposal for a 01 Series of Amendments to UN Regulation No. 173 to the June 2025 sessions of WP.29 and AC.1.

12. The expert from the Kingdom of the Netherlands presented informal document GRSP-76-17 on behalf of the Technical Services Group. The proposal was well received by GRSP and he announced his intention to come back with a working document to the next session of GRSP.

13. The expert from OICA presented informal document GRSP-76-45 with a minor correction to UN Regulation No. 173. GRSP adopted the proposal (see annex IV to the session report, section B) and requested the secretariat to submit it as proposal of Supplement 1 to the Original Series of Amendments of UN Regulation No. 173 to the June 2025 sessions of WP.29 and AC.1. (Note: The same correction was also added to informal document GRSP-76-32-Rev.1, amending the 01 series of amendments (see paragraph 11 and annex IV, section A).)

14. The expert from Germany discussed a public warning issued by the German Type Approval Authority on universal ISOFIX adapters (see informal document GRSP-76-42-Rev.1). Tests of these devices showed that life-threatening injuries were to be expected in the event of an accident. The issued warning states: “Child seats must bear an approval mark. These must only be connected to the vehicle’s tested and approved ISOFIX anchorage points, which is not the case with these products, and could result in significant risk to the child.”. Germany encouraged other contracting parties to follow the same approach. GRSP acknowledged the gravity of the problem and requested the Chair to include this issue in the highlights of his report to WP.29.
