Proposal as approved by the GRSP to introduce new provisions for folding seats.

Proposal to define the moment of inertia in the luggage-impact test as “0.3 ± 0.05 kgm2 (around all 3 principal axis of inertia of the luggage blocks)”. UN R17 presently lacks such a definition, resulting in variations in trajectory and behavior of the luggage cubes before and after impact. This proposal would also correct a reference to UN R25 to refer to the 04 series of amendments rather than to the 03 series of amendments.

Proposal to clarify the testing of seats with and without head restraints. This proposal would allow alternatives at the request of the manufacturer by clarifying that under testing of a bench seat with three seating positions and two head restraints, a moment of 3 × 373Nm shall be applied to the back of seats and of 2 × 373Nm to the head restraints:

1. If the manufacturer wants to comply with the test requirements of paragraph 6.2. (strength of the seat-back), by the test of head restraint performance of paragraph 6.4., they choose to apply 53 daNm to each seat back without head restraint and 89 daN to each head restraint. In this case only one test shall be performed.
2. If the manufacturer chooses not to apply 53 daNm, during the test of paragraph 6.4., the seat back strength test of paragraph 6.2. has to be performed in addition to the test of paragraph 6.4.

Proposal to require seat belt components such as retractors to remain functional if damaged during the load-retention test according to Annex 9 of UN R17. Such components have occasionally been damaged during testing such that their functionality has been impaired. In order to ensure adequate occupant safety, this proposal would require all safety-belt components to be included in the test installation and require post-test inspection to confirm the continued functionality. The transitional provisions phase in the new requirements during September 2020-September 2022.

GRSP proposal to transpose provisions of UN Global Technical Regulation No. 7, Phase 2 into UN Regulation No. 17.

Proposal to clarify the possibility to install side-facing seats in buses of category M2 and M3 of classes A and I.

Proposal to correct the cross-reference to paragraph 5.11. in paragraph 6.4.3.5. The text should refer to paragraph 5.12.

Proposal to enable approval of all vehicles and seating positions with regard to the strength of seats and their anchorages and with regard to their head restraints (in addition to M₁ and N₁) under UN R17. (Note: WP.29 deferred a decision on adoption of this proposal during the November 2023 session.)

Proposal to ensure that only safe head restraints are fitted to seats of any seating position in all vehicle categories within the scope of UN R17 and to extend the test performance of paragraph 5.7.4 (height retention of head restraints) to non-adjustable head restraint with only one position of use.

Proposal to update references to the three-dimensional “H” point measurement and calibration procedure pursuant to the transposition of these provisions from the Consolidated Resolution on the Construction of Vehicles (RE3) to Mutual Resolution No. 1.
