4. GRSP Chair, informed GRSP of the discussion held at the March 2021 session of the Executive Committee of the 1998 Agreement (AC.3) (see ECE/TRANS/WP.29/1157, paras. 143 to 148). GRSP Chair recalled GRSP that AC.3 agreed to defer vote under this agenda item to its June 2021 session pending further discussions concerning the proposal for Amendment 3 to UN Global Technical Regulation (UN GTR) No. 9 at the next session of GRSP, scheduled to take place in May 2021. He also reminded that AC.3 requested GRSP to give highest priority to the task and to report back to AC.3 and WP.29 with the greatest urgency on the progress towards a resolution of outstanding matters in this context. He continued that to that end, he had contacted the concerned Contracting Parties including AC.3 Chair and the GRSP Secretary, to meet at the earliest possible date and asked the new expert representing the United States of America to report on the developments since WP.29. The expert of the United States of America informed GRSP about the meeting of the interested experts held virtually on April 23, when especially the experts from the United States of America and Germany, presented on the findings and conclusions of their respective experts. It was agreed that more discussions are warranted and with inclusion of the industry. During that time, United States of America and Germany continued the dialogue and exchanges of views and technical information to find a solution. She also added that experts met on Monday, May 17, just prior to GRSP meeting and agreed to establish as soon as possible a task force to solve the issue between the May and December 2021 GRSP sessions. She assumed that the first meeting of the task Force would be held on June 14 and that most likely a proposal would be ready by the GRSP meeting in December 2021. The experts from Germany, EC, Canada, United Kingdom of Great Britain and Northern Ireland, Japan, the Netherlands, and Republic of Korea, supported the United States of America approach and underlined the relevance of timing. The expert from the United States of America proposed to include other relevant issues in the programme of work of the Task Force. The expert from OICA stressed the importance not to delay the finalisation of the extension of the impact zone, explaining that this is urgently needed due to the European Union requirements of the General Safety Regulation which are already decided in general (including the application dates), but which are currently under development in the framework of UN Regulation N° 127. He feared that, if such topics are referred back to GTR N°9, then the deadlines would not be respected, creating for industry a legal void. The experts from the Netherlands and the United States of America introduced GRSP-69-43-Rev.1 amending the previous authorization to develop Amendment 3 (ECE/TRANS/WP.29/AC.3/31). GRSP recommended on provisional basis ECE/TRANS/WP.29/AC.3/31/Rev.1, as reproduced in Annex II to this report, to provide a revised request of authorization of work to finalize Amendment 3 to UN GTR No. 9 (Pedestrian safety) for consideration to the June 2021 session of AC.3. To ensure the work proceeds in a timely manner, GRSP agreed to establish a Task Force, and it was recommended to withdraw the current proposed Amendment 3 from consideration and vote at the June 2021 session of AC.3. Moreover, GRSP agreed to forward documents under agenda item 11 (ECE/TRANS/WP.29/GRSP/2019/18, ECE/TRANS/WP.29/GRSP/2020/9 and GRSP-69-21-Rev.1) to the TF for consideration (see para. 20 below).

GRSP-69-21/Rev.1 | UN R127: Proposal for the 03 series of amendments Counter-proposal from OICA to a German proposal (GRSP/2019/18) to address vehicles with active suspensions and amend the definitions and specifications and Annex 1, Part 1. This document supersedes previous OICA submissions GRSP-67-07 and GRSP-68-18.

GRSP-69-43/Rev.1 | GTR 9: Proposal for an amendment to the Authorization for the development of amendments This document contains a proposal to continue to develop amendments to UN GTR No. 9 on pedestrian safety in order to clarify the test procedures. It is based on ECE/TRANS/WP.29/AC.3/31 from the March 2012 session of the Executive Committee (AC.3) of the 1998 Agreement. It is distributed to the World Forum for Harmonization of Vehicle Regulations (WP.29) and to AC.3 for consideration. This document shall be appended to the amendment to the UN GTR once adopted.

GRSP/2020/9 | UN R127 : Proposal for 03 series of amendments Proposal by the expert from EC on behalf of the Drafting Task Force to align the UN Regulation with the revised General Safety Regulation of the European Union – appropriate transitional provisions, and minor adaptations and clarifications to the existing requirements. This proposal will allow contracting parties to apply an enlarged head impact zone for regulatory compliance testing.

5. Concerning the issue of different heights of the vehicle from adjustable suspension systems, the expert from Germany withdrew GRSP-65-17 and informed GRSP that a revised proposal would be submitted at the December 2021 session.

GRSP-65-17 | GTR 9: Proposal for Amendment 3 Proposal to ensure pedestrian safety across the vehicle height variations that may be produced by active suspensions.

6. The expert from the Republic of Korea introduced GRSP-69-20, providing the progress report of the Informal Working Group on Deployable Pedestrian Protection Systems (IWG-DPPS). He confirmed his previous statement at the December 2020 session of GRSP that due to the limitation caused by the COVID-19 pandemic, the IWG had still open issues and the finalization of a proposal would be expected by May 2022 session of GRSP. Accordingly, he requested the extension of the mandate until November 2022. In the meantime, he requested the official position of Contracting Parties on applying the numerical simulation method to the proposed requirements to the UN Regulation/UN GTR. He explained that this would constitute the core proposed amendments and in the case of a negative response of CPs this would have a negative effect on the work performed so far by the IWG. GRSP endorsed the request of the expert from the Republic of Korea to extend the mandate of the IWG to seek endorsement of WP.29 and AC.3 at their June 2021 sessions. Moreover, GRSP requested experts of C.P.s of both 1958 and 1998 Agreements to provide an answer to the Chair of the IWG concerning the simulation method by the December 2021 session of GRSP at the latest. The expert from United States of America announced her participation in the next IWG meeting.

9. GRSP noted the proposal tabled by expert from the Netherlands (GRSP-69-08) to introduce requirements concerning post-crash electrical safety as was agreed for UN Regulation No. 94 (Frontal collision). GRSP requested the secretariat to distribute GRSP-69-08 with an official symbol at its December 2021 session, pending a further revision submitted by the expert of the Netherlands by the deadline for submission of official documents.

GRSP-69-08 | UN R12: Proposal for a 05 series of amendments Proposal to align UN R12 with the provisions of GTR 20 on post-crash electrical safety, the administrative provisions of Revision 3 to the 1958 Agreement. The amendments only impact the approval of vehicles with an electric power train operating at high voltage.

10. The expert from Germany introduced ECE/TRANS/WP.29/GRSP/2021/9, concerning the minimum number of lower anchorages for folding seat. In the same time GRSP considered GRSP-69-35 to amend the reference to Consolidated Resolution on the Construction of Vehicles (R.E.3) (Annex 13, Appendix 1) by a reference to UN Regulation No. 16, Annex 16, in the note on two anchorages. GRSP adopted ECE/TRANS/WP.29/GRSP/2021/9 as amended by Annex III to the report. The secretariat was requested to submit the proposal as the draft Supplement 9 to the 07 series of amendments, Supplement 1 to the 08 series of amendments and Supplement 2 to the 09 series of amendments to UN Regulation No. 14, for consideration and vote at the November 2021 sessions of WP.29 and to the Administrative Committee of the 1958 Agreement (AC.1).

GRSP-69-35 | UN R14: Proposal for amendment to ECE/TRANS/WP.29/GRSP/2021/9 Proposal from the GRSP secretariat to clarify the text of the formal proposal GRSP/2021/9.

GRSP/2021/9 | UN R14: Proposal for Supplement 9 to 07 series of amendments, Supplement 1 to 08 series of amendments, Supplement 2 to the 09 series of amendments Corrects an inconsistency in Annex 6 – Appendix 1, with regard to the minimum number of lower anchorages for folding seats.

11. GRSP considered and adopted ECE/TRANS/WP.29/GRSP/2021/10, to amend an omission in paragraph 3 of the UN Regulation, with regard to information on safety-belt reminders and ECE/TRANS/WP.29/GRSP/2021/16, both not amended, as a correction to the information sheet (Certificate) in its paragraph 3.3. The secretariat was requested to submit the proposals as draft Supplement 7 to the 07 series of amendments, draft Supplement 3 to the 08 series of amendments (ECE/TRANS/WP.29/GRSP/2021/10) and Corrigendum 1 to Supplement 12 to the 06 series of amendments (ECE/TRANS/WP.29/GRSP/2021/16) to UN Regulation No. 16 (Safety-belts) for consideration and vote at the November 2021 sessions of WP.29 and to AC.1.

12. GRSP resumed discussion on ECE/TRANS/WP.29/GRSP/2019/15 and GRSP-66-14, on the subject of an alternative (at the choice of the manufacturer) airbag switch-off for frontal airbags in combination with rearward-facing child restraint systems in the rear seat. The expert from the International Organization of Motor Vehicle Manufacturers, clarified that some informal meetings had taken place to explain the proposal and that general support was received. However, he explained that further research was needed on soft air-bag technology and requested GRSP further feedback on this subject. The expert from the United Kingdom expressed concerns to the proposal and requested robust evidence and rationales looking forward for a revised proposal. The expert from EC clarified that he needed to have consultation with European Union (EU) member states whether or not the approach would be acceptable, namely placing a rearward facing Child Restraint Systems on a place with active front airbag, since this is not compatible with safety-belt wearing Directive 91/671/EEC and must be amended as a result. Hence, it is necessary to have an overview of EU Member States views.". GRSP agreed to resume discussion on this subject at its December 2021 session, on the basis of a revised proposal prepared by the expert from OICA in consultation with interested parties.

GRSP-66-14 | UN R16: Proposal to amend document GRSP/2019/15 (Supplement 6 to the 07 series and Supplement 1 to 08 series of amendments) Proposal to clarify the test procedures and the different ECRS to be tested for the assessment of the system.

13. The expert from Japan introduced GRSP-69-23 through a presentation (GRSP-69-24), aimed at solving the issue of safety-belt slipping up to the neck and submarining occurring in some cases when the booster seat was fixed to the vehicle by an ISOFIX attachment increasing the risk of child occupant’s neck and abdomen injuries. The experts from the CLEPA and OICA requested a study reservation on the proposal. GRSP agreed to resume discussion at its December 2021 session and requested the secretariat to distribute GRSP-69-23 with an official symbol at its next session.

GRSP-69-23 | UN R16: Proposal for the 09 series of amendments Proposal to address safety-belt slippage up to the neck and submarining in ISOFIX-attached child booster seats.

15. The expert from Japan reiterated his concerns to ECE/TRANS/WP.29/GRSP/2020/12, tabled by the expert from OICA, to clarify the test procedure for the height of head restraints in the case of vehicles having a low roof construction (see ECE/TRANS/WP.29/GRSP/68, para. 11). He finally requested time for further analysis. In the same time, the expert from CLEPA requested to be involved in the consultation. GRSP agreed to defer consideration of the proposal at its December 2021 session.

GRSP/2020/12 | UN R17: Proposal for Supplement 1 to the 10 series of amendments Proposal to clarify the test procedure for the height of head restraints in the case of vehicles having a low roof construction.

16. The expert from Norway introduced a presentation (GRSP-69-06) concerning the main findings of a report (GRSP-69-02) from the Norwegian Safety Investigation Authority (NSIA) related to a high-speed frontal road-collision. He added that the car collision occurred between a passenger car and a van and that two passengers seating in the rear seat row died during the collision also due to the luggage displacement, while frontal seating passengers sustained minor injuries. The expert from Consumer International (CI) proposed that more stringent requirements for rear seat strength should be introduced into the UN Regulation. The expert from EC stated his intention to study the case and report at the next GRSP sessions. The expert from OICA argued that crash speed (80 km/h) of the reported accident was beyond the speed considered into the UN Regulation. Moreover, he suggested that also harmonized international traffic rules on the obligation of securing luggage should be pursued. GRSP agreed to resume discussion on this subject and defer discussion on GRSP-69-34 at its December 2021 session.

GRSP-69-02 | Report on a Head-On Collision between a Passenger Car and a Van in Norway on 20 Oct 2019 Analysis of a fatal crash event involving a van the lost its grip on the ice-covered road surface, crossed into the opposite lane and collided head-on with an estate car of approximately the same weight, fully laden with passengers. The investigation showed that the back of the rear seat was severely deformed, despite being reinforced and well within the regulatory strength requirements described in UN-ECE R17.

GRSP-69-34 | UN R17: Proposal for Corrigendum 1 to the 10 series of amendments Proposal from the GRSP secretariat to correct a transposition error between GRSP/2020/8 and the text in WP.29/2020/106. The WP.29 text as adopted omitted the deletion in para. 1.4.2.2.: "The <strike>front and</strike> rear zones are respectively bounded by the horizontal plane tangential to the top of the head restraint as determined in paragraph 6.5. of this Regulation."

17. The expert from Italy, Chair of the ad-hoc group on safety helmets introduced ECE/TRANS/WP.29/GRSP/2021/13, through a presentation (GRSP-69-19) to address the need of a text that can be enforced in a practical manner until specific requirements for the type approval of helmet accessories would be defined. GRSP adopted ECE/TRANS/WP.29/GRSP/2021/13, as amended by (GRSP-69-17) Annex IV of the session report. The secretariat was requested to submit the proposal, as draft Supplement 1 to the 06 series of amendment to UN Regulation No. 22 (Protective helmets), for consideration and vote at the November 2021 session of WP.29 and to AC.1.

GRSP-69-17 | UN R22: Proposal of Supplement 2 to the 06 series of amendments Proposal to introduce a tolerance for eye protection assessment.

Changes introduced by customers on helmets are not covered once the helmet has been type-approved.

18. GRSP also noted ECE/TRANS/WP.29/GRSP/2021/15, amended by GRSP-69-18 aimed at preventing the issue of invalidating a UN Approval with the use of an aftermarket product. The proposal received some comments from the experts of Euromed (GRSP-69-26) and proposed changes from the expert from Italy (GRSP-69-32). GRSP Chair and the Chair of the ad-hoc group proposed to convey the above proposals into the activity of the ad-hoc group on safety-helmets. The expert from Euromed argued that the for sake of transparency it was advisable to establish an informal working group (IWG) and he introduced the terms of reference of the IWG (GRSP-69-36). However, concerns were expressed about the number of interested experts and about the need to be much more responsive in providing a possible solution to the December 2021 session. Following the suggestion of the expert from the Netherlands, GRSP agreed to continue the activities of the ad-hoc group and requested the secretariat to provide a wiki page on the ECE website. In the meantime, it was clarified that rules of procedure of IWGs, ad-hoc group, Task Force shall be the same of those of parent group. Accordingly, GRSP reminded all the Chairs and secretaries of the above-mentioned groups to verify consistent credentials of attendees and receive copyright disclaimers for documents posted on UNECE website. GRSP agreed to resume the discussion on this subject waiting the outcome of discussion of the ad-hoc group on ECE/TRANS/WP.29/GRSP/2021/15, GRSP-69-26, GRSP-69-32 and GRSP-69-36.

21. GRSP considered GRSP-69-09, concerning the interpretation of the expert from the Netherlands on the way “one belt route” defined by the current text of UN Regulation No. 129 (Enhanced Child Restraint Systems). He also requested guidance to GRSP how to deal in the future with questions of this kind. GRSP agreed on the interpretation provided by the expert from the Netherlands:

""one belt route" shall be strictly interpreted, only asymmetrical attachments can still be regarded as “one belt route”

GRSP agreed that such an interpretation would not need to amend the current text of UN Regulation No. 129. Moreover, GRSP agreed that such decision would be reported orally by the Chair of GRSP at the June 2021 session of WP.29 as well as the request of guidance to address issue of interpretations of this kind in a more coordinated way in the work of WP.29 and its subsidiary bodies.
