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 update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019, to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129, and to reconcile and consolidate various references to tolerances for the internal geometry assessment.

Proposal to clarify the requirements for the type approval category of booster seats over 135 cm, to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019, to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129, and to reconcile and consolidate various references to tolerances for the internal geometry assessment.

Proposal

• to clarify the requirements for the type approval of booster seats in the over 135 cm category,
• to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019,
• to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129,
• to reconcile and consolidate various references to tolerances for the internal geometry assessment, and
• to exclude the head acceleration criterion in certain cases of contact when testing booster cushions with the larger Q-dummies, in particular the Q10, due to dummy rebound over the back of the test bench during a frontal test.

Proposal to specify the Q6 dummy in lieu of the Q3 with regard to integral ECRS testing and to add the Q3 to the already existing Q6 under the 02 series of amendments.

Proposal for a new UN Regulation for the type approval of M₁ vehicles with a total permissible mass not exceeding 3,500 kg and of N₁ with regard to fuel integrity and safety of high voltage systems in case of a rear-end collision. This proposal aligns rear impact (UN R34) and electric vehicle safety (UN R100) requirements with the new EU General Safety Regulation and 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.

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.

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 align UN R95 with GTR 20.

Proposed changes to align UN R137 with GTR 20.

Consolidated version of the revised UN R100.

Proposed changes to UN R100 (non-consolidated with the current UN R100).
