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

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.

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

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

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 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.

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

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 the chest Z axis measurement requirement.

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).
