Agenda item 20. UN Regulation No. 129 (Enhanced Child Restraint Systems)

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.

GRSP | Session 63 | 14-18 May 2018

32. The expert from Spain introduced ECE/TRANS/WP.29/GRSP/2018/17 and ECE/TRANS/WP.29/GRSP/2018/18 which clarify that an i-Size booster seat (Non-Integral Enhanced Child Restraint System) can accommodate children with a maximum stature of 135 cm. The expert from CLEPA introduced GRSP-63-28, explaining that the current text of the UN Regulation is consistent with the approach for backrest angle and that an adjustment for over 135 was a “comfort feature”. GRSP agreed to resume discussion on this subject on the basis of revised proposals.

40. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2019/35 to clarify some requirements of the UN Regulation. He added that the same clarification should be introduced in all the other series of amendments including the original version: ECE/TRANS/WP.29/GRSP/2019/32, ECE/TRANS/WP.29/GRSP/2019/33 and ECE/TRANS/WP.29/GRSP/2019/34. The expert from Spain introduced GRSP-66-02, to extend the requirements of a minimum breaking load to the webbing straps of all categories of integral enhanced child restraint systems, not only i-Size. She also explained that the proposal would clarify that integral belted Enhanced Child Restraint Systems (ECRS) categories should explicitly require testing of rear or lateral impact. The expert from Japan introduced GRSP-66-10 to correct the table of the injury assessment criteria. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2019/32, ECE/TRANS/WP.29/GRSP/2019/33, ECE/TRANS/WP.29/GRSP/2019/34, all as amended by (GRSP-66-10) Annex VIII and ECE/TRANS/WP.29/GRSP/2019/35, as amended by (GRSP-66-10 and GRSP-66-02, paras. 6.7.4.3. to 6.7.4.3.4. excluded) annex VIII to the session report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2019/32 as Supplement 10 to the original series of amendments, ECE/TRANS/WP.29/GRSP/2019/33 as Supplement 7 to the 01 series of amendments, ECE/TRANS/WP.29/GRSP/2019/34 as Supplement 6 to the 02 series of amendments and ECE/TRANS/WP.29/GRSP/2019/35 as Supplement 4 to the 03 series of amendments to UN Regulation No. 129, for consideration and vote at the June 2020 sessions of WP.29 and AC.1. Finally, agreed to resume discussion on a revised proposal (GRSP-66-02) tabled by the expert from Spain on minimum breaking load of the webbing straps (paras. 6.7.4.3. to 6.7.4.3.4.) as a new series of amendments, at its May 2020 session.
