This report was reissued on 1 March 2019 for technical reasons.

Proposal to clarify rounded-edge requirements for roof-opening roof devices.

Request for interpretation of UN R17 for testing of head restraints in cases where the head restraint is not mandatory in the vehicle category in question.

Proposal to introduce chest vertical acceleration (Az) criteria until such time as upper neck tension Force (Fz) and upper neck flexion moment (My) criteria can be established.

Proposal to update the text of UN R100, particularly in line with GTR 20 on electric vehicle safety.

Proposal to introduce an optional (on the choice of the manufacturer) test procedure for frontal airbags in combination with rearward facing child restraint systems in the rear seat to demonstrate that no deactivation of the airbag is needed.

Presentation in support of the proposal to allow an option for demonstration that an airbag deployment is safe in the presence of a rear-facing child restraint system in a rear seating position.

Proposal to expand the scope of the Regulation (to vehicles of category M₁ with a maximum permissible mass not exceeding 3500 kg and to vehicles of category N₁, to provide appropriate transitional provisions and to make minor adaptations and clarifications to the existing requirements.

Proposal to remove restrictions on the scope of the Regulation to M₁ and N₁ vehicles, to provide appropriate transitional provisions and to make minor adaptations and clarifications to the existing requirements.

Proposal to expand the scope of the Regulation to cover vehicles of category M₁ with a total permissible mass not exceeding 3500 kg and to vehicles of category N₁ with a total permissible mass not exceeding 2500 kg, to provide transitional provisions (May 2022/May 2024) and to make minor adaptations and clarifications to the existing requirements.

Provisional edition of the adopted text for new vehicle safety requirements in the European Union.

Proposal to ensure pedestrian safety across the vehicle height variations that may be produced by active suspensions.

Proposal to clarify the definitions of integrated and detachable head restraints.

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

Request for guidance in order to resolve conflicting interpretations of paragraph 7.1.4.2.2. The paragraphs reads, " The vertical component of the acceleration from the abdomen towards the head shall not exceed 30 g except during periods whose sum does not exceed 3 ms.” However, an explanatory note for Technical Services on performing the tests under Annex 15 adds, "The wording of this paragraph [7.1.4.2.2.] refers to accelerations representing tensile loads in the spine of the dummy.” Differing interpretations have resulted in a CRS being approved but then rejected during Conformity of Production review by a separate Technical Service.

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

Report on Korea regulation obligating a check of school buses to ensure that all children have left the vehicle. The check involves installation of a device at the back of the bus that will sound an alarm unless engaged within three minutes after engine shutoff.

Information on the regulation of category L7 micro four-wheeled vehicles.

Updated proposal (based on document GRSP/2019/5) to specify a head restraint height between 720 mm and 830 mm including a new method for measuring the effective height of head restraints, use of the Biofidelic Rear Impact Device (BioRID II) test dummy, and to improve the overall text. This proposal also eliminates the backset measurement test procedure using the HRMD method.

Final refinements developed during the May 2019 GRSP session to the proposal to include booster cushion categories within the scope of the 03 series of amendments to UN R129 (Supplement 3 to the 03 series).

Proposal to clarify the chest Z axis measurement requirement.

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).

Proposal to amend document GRSP/2019/10. The proposal clarifies the way to apply and to understand GTR7 phase 2 static alternative provisions and aligns the area where the gap is measured to actual practice in UN R17 and FMVSS 202a which consider only gaps over a height of 540mm.

Proposal to clarify that the warning signal to alert a driver of an M₂ or M₃ vehicle with more than 22 seating positions if the vehicle is in active-driving-possible mode when the driver leaves the seat shall be activated upon leaving the seat, not the vehicle.

Proposal to introduce objective criteria for evaluating whether a door remains latched following the pole impact test. Under UN R135, rear doors on the impacted side of the vehicle not directly struck by the pole may nonetheless be subjected to heavy loads and therefore need to be assessed. This proposal corresponds to a similar clarification already introduced into UN R95 on side impacts.

Proposal to:

• Remove a residual reference in Annex 22 to ‘temporary’ requirements for belt-attached infant carrier modules;
• Extend and adapt the minimum breaking load requirements to cover the webbing straps of all categories of integral enhanced child restraint systems (not only i-Size); and
• Clarify that Integral Belted enhanced child restraint categories are required to undergo rear or lateral dynamic impact testing.

Proposal to establish labeling requirements for hydrogen-fueled buses consistent with that existing for LPG-, CNG-, and LNG-fueled buses.

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.

Finnish Safety Investigation Authority has given recommendation to equip the seats of category M₂ and M_{3</ vehicles with lap and shoulder belt type seat belts, i.e. three-point seat belts.}

Proposal to align UN R129 with the descriptions used in of UN R44 and UN R94 which refer to resultant head and chest accelerations.

Proposal to provide information on the essential measurement information that needs to be recorded in the Type Approval test report

Proposal to improve the repeatability and reproducibility of the assessment of the external dimensions of the ECRS. It does not change any current dimensional requirements relating to the sizes of the body of the ECRS, the support leg or the support leg foot.
