The proposal addresses new airbag technologies pursuant to discussions during the December 2021 session of GRSP (see GRSP/70, paragraph 12). The proposal was revised to limit the scope to specific Enhanced Child Restraint Systems (ECRS).

16. GRSP resumed discussion on a proposal (ECE/TRANS/WP.29/GRSP/2022/13) tabled by the expert from France on clarifying the assessment of the connection of the Safety-Belt Reminder (SBR) system in the case of removable seats.

He introduced ECE/TRANS/WP.29/GRSP/2022/21 that covers the same provisions of ECE/TRANS/WP.29/GRSP/2022/20 in a new series of amendments, and also extends the test performance of paragraph 5.7.4 (height retention of head restraints) to non-adjustable head restraint with only one position of use. The expert from CLEPA argued that the proposed deletion of the reference to UN Regulation No. 25 in both proposals would introduce unclarity when head restraint would be type approved as separate technical units. The expert from Germany stated that UN Regulation No. 25 was not updated to the technical progress. He added that the aftermarket was regulated by national law while the type approval of vehicles should be regulated by UN Regulation No. 17.

21. Finally, GRSP agreed to resume discussion on ECE/TRANS/WP.29/GRSP/2022/20 and ECE/TRANS/WP.29/GRSP/2022/21 at its May 2023 session.

All head restraints fitted on seats under the scope of UN Regulation No. 17 shall be approved.” GRSP agreed that a group of interested experts would cooperate on a solution, led by the expert from Germany.

GRSP/2022/20 | UN R17: Proposal for Supplement 1 to the 10 series of amendments Proposal to bring align the current text with scope of the Regulation and ensure that only safe head restraints will be fitted to seats in all seating positions and all vehicle categories as specified in the scope.

The expert from OICA suggested that the interpretation laid out in the document was intended to be general and was to be applied with flexibility in specific cases. Finally, GRSP agreed to provide feedback to the expert from Japan on GRSP-72-07-Rev.1 by the end of January 2023.

He thus introduced a proposal of amendment to UN Regulation No. 16 (Safety-belts) prohibiting UI use (GRSP-72-39). GRSP requested the secretariat to distribute GRSP-72-39 with an official symbol at its May 2023 session. At the same time GRSP agreed to resume discussion on GRSP-72-15 at its May 2023 session based on the feedback provided by the expert from OICA.
