Submmission aimed at resolving errors in the current text of the UN Regulation concerning the anchorage angles (α1 and α2) and the seating reference point (R-point).

Text of the proposed regulation on safety-related performance requirements for hydrogen-fueled vehicles as prepared by the GRSP working group on Hydrogen and Fuel Cell Vehicles – Subgroup safety (HFCV-SGS). This draft supersedes document GRSP/2012/12.

Proposal from Germany for Supplement 2 to the 02 series of amendments and for Supplement 1 to the 03 series of amendments of Regulation No. 29 primarily to add further possibilities for the seating arrangement of test dummies.

Text prepared by Germany proposing to introduce new provisions for folding seats.
.

The current text of UN R14 requires the installation of two ISOFIX anchorages in a vehicle. Vehicles with only one seat row are exempted from this requirement. This proposal introduces provisions for at least one set of ISOFIX anchorages in vehicles having only one seat row or having several seat rows with only one seat per row.

Certain anti-theft systems fully lock every door and window in a vehicle and also deactivate interior unlock controls. This can lead to a situation where an occupant can be locked inside a vehicle with no means of exit save to break a window. This proposal would require countermeasures to prevent such a situation.

Proposal to specify a head restraint height between 720 mm and 830 mm pursuant to the work on phase 2 of GTR No. 7 which includes a new method for measuring the effective height of head restraints.

Certain anti-theft systems fully lock every door and window in a vehicle and also deactivate interior unlock controls. This can lead to a situation where an occupant can be locked inside a vehicle with no means of exit save to break a window. This proposal would introduce provisions for the safety and protection of road vehicle occupants in case of the installation of such a full locking system.

Proposal to extend the prohibition against the installation of side-facing seats to all categories of commercial vehicles (N).

Proposal to amend the scope and clarify the transitional provisions to avoid misinterpretations for the installation of side-facing seats in category M3 vehicles. 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.

The 03 series of amendment introduced a new Test C into UN Regulation No. 29. This proposal adds specifications for the test rig in the case where a pendulum impactor is used (as is already prescribed for Tests A and B. To improve the repeatability of the test, the submission further proposes to place the cab on a horizontal surface and to fix the pendulum with a required angle of 20° of impact against the cab to be tested.

Proposal to clarify the text of UN R14. The current text has produced differing interpretations among Technical Services with regard to which requirements apply to central seating positions in rear rows of category M₁ and N₁ vehicles and the minimum distance between two effective lower belt anchorages (L1 and L2). The proposed amendments clarify that a reduced minimum distance of 240 mm is only allowed in the case where there is only one central seating position (i.e. in a row of 3 seating positions). Rear seat rows with an even number of seats always shall have a distance of at least 350 mm. Given that it entails new requirements, the proposal is presented as a new series of amendments with transitional provisions (proposed through 2025).

Proposal to clarify that seat belt components such as retractors shall not sustain damage during testing 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 absence of damage.

Proposal to introduce installation specifications for securing a cab mounted on a vehicle to the test rig for tests B and C, as is currently provided for test A, under UN R29. This proposal aims to improve repeatability and reproducibility while allowing more flexibility in permitting the use of rigid composite blocks and/or (adjustable) metal brackets in securing the vehicle in the place of the wooden block presently prescribed in Figure 1.

Proposal to clarify the conditions where a door is deemed to be open under UN R95. Technical Services have interpreted the definition of “open” under paragraph 5.3.1. differently, resulting in divergent outcomes. The proposed definitions are taken from UN Regulation No. 135 Revision 1.

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.

Proposal to introduce installation specifications for securing a cab mounted on a vehicle to the test rig for tests B and C, as is currently provided for test A, under UN R29. This proposal aims to improve repeatability and reproducibility while allowing more flexibility in permitting the use of rigid composite blocks and/or (adjustable) metal brackets in securing the vehicle in the place of the wooden block presently prescribed in Figure 1.

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 introduce a tolerance for the position of the loading device during the test. The loading device is required to be parallel to the x-y plane of the chassis. This proposal would add a z dimension to the x-y plane and set a tolerance such that the loading device may not deviate by more than 5° along the z-axis.

Proposal to amend the definition of integrated, detachable and separate head restraint.

Proposal to ensure pedestrian protection across the vehicle height variations that may be produced by an active suspension system.

Introduces wording to clarify that the performance of protective helmets may be affected by using accessories not tested during the type approval procedure. Changes introduced by customers on helmets are not covered once the helmet has been type-approved.

Defines parameters to enable a reproducible measurement of the acute angle alpha (α) to decide if the vehicle is or is not in the scope of the regulation.

Proposal to clarify the conditions under which variations of a vehicle can be covered under a single vehicle type without having to apply for a separate approval for another type. The proposal amends certain current provisions that explicitly state that differences will only cause a new type of vehicle if the differences affect the results of the impact test and clarifies the application of this principle across the regulation.

Proposal to introduce new requirements to address vehicles equipped with Adjustable Ride Height Suspension Systems (ARHSS).

Proposal for clarifications to the text (subsequent to documents WP.29/2022/70, WP.29/2022/129 and WP.29/2022/130), especially relating to the definitions of the cowl monitoring, the windscreen, and the jerk areas.

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.

Proposal to reinsert text allowing tolerances on the vehicle mass and simplified testing that was deleted by the 02 series of amendments.
