Integrated into the regulation through Revision 2.

Proposal to limit the overlap of this head restraint regulation with UN R17 which also addresses head restraints within the context of seat integrity. The amendment would exempt any vehicle head restraints approved under UN R17 from the requirements of UN R25. Presently, only M1 passenger cars qualify for this derogation.

UN R17, R25 and R80 address head restraints for various categories of vehicles. In order to prevent redundant application of these regulations, this amendment clarifies that head restraints approved under UN R17 would be exempted from the requirements of UN R25 and that UN R25 does not apply to coach and bus seats approved under UN R80.

Correction to include provisions for the exemption of certain headrests of M₂ and M₃ vehicles approved according to UN R80.

Proposal to amend the scope and clarify the transitional provisions to avoid misinterpretations for the installation of side-facing seats in category M₃vehicles. The proposal exempts vehicles exceeding 10 tonnes from the prohibition on side-facing seat provided the seat meet conditions specified in the 03 series of amendments to the Regulation.

In response to proposals to allow greater forward displacement of occupants under UN R16 and the resulting changes in impact energy-dissipation criteria under UN R17, UN R25 (with regard to head restraints) is also subject to change. This proposal would accordingly update a reference in UN R80 to UN R25.

UN R80, paragraph 7.4.4. specifies that passengers in side-facing seats “shall be safeguarded by a vehicle part (e.g. partition, wall or seat back of a forward-facing seat) forward of the foremost side-facing seat”. Germany has determined that the current text has been misinterpreted with regard to the intended requirement for a safety device that does not break and maintains its capability to retain a passenger’s body in the event of an accident. This proposal clarifies that such any such structure “shall retain its safeguard function during testing”.

Under UN R80, head restraints must comply with the requirements of UN R25. This proposal updates the reference to UN R25 to specify compliance according to the 04 series of amendments (from the current reference to the 03 series of amendments). This change thus updates UN R80 to incorporate changes in impact-energy dissipation criteria made to UN R25 pursuant to changes allowing greater forward displacement of occupants under UN R16.

Research has shown that dynamic testing under Appendix 1 is more demanding than the static testing under Appendix 5. As a result, approvals based upon static testing are not equivalent to approvals based on dynamic testing. This proposal, therefore, would delete Appendix 5. In addition, this proposal amends Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN Regulation No. 14. Further, the proposal would limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.

Presentation in support of the proposal to delete the static test procedure for seat strength (document GRSP-62-12) from UN R80.

Proposal to delete Appendix 5 and thereby end static testing as a compliance option. In addition, this proposal amends Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN Regulation No. 14. Further, the proposal would limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.

Proposal to amend to document GRSP/2018/10 in order to clarify the torque specification for attaching seats and to delay the proposed entry into force.

Proposal to add injury criteria in relation to the neck bending moment along the lateral axis (not to exceed 57 Nm when stretched), clarify the distance between the seats to align with IN R107, and annulation of the proposal to delete paragraph 2.1.2 because the scope of UN R80 provides for testing of seats for vehicles of M₂ and M₃ categories of II, III and B classes where approval is allowed via testing without a vehicle and mounted rigidly on a test platform.

Proposal to delete Appendix 5 as a basis for type approval and thereby end static testing as a compliance option.

Proposal to amend Appendix 1 by reducing the forward movement of the head of the manikin to 1.2 m in alignment with UN R14. The proposal would also limit the movement of the seat anchorages to 100 mm to ensure a minimum residual space for the passenger between the seats. Lastly, to ensure that seat fixations are reliably fastened after relocation, the proposal would require the necessary information to be marked directly on the seat and provided in the owner’s manual.

Proposal to raise requirements for the attachments and fittings of the seat (as a prelude to the eventual deletion of static test methods in favor of dynamic testing).

Finnish Safety Investigation Authority has given a recommendation to introduce a change UN Regulation No 80 regarding the structure of the back part of seats for the purpose of making them safer, by adding padding and removing hard protrusions located right in the front of passengers.

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.

Revised proposal based on document GRSP/2024/7 to update references to the three-dimensional “H” point measurement and calibration procedure pursuant to moving such provisions from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1.
