35. The expert from CLEPA introduced a summary of all the documents that he had submitted (GRSP-64-29) and presented GRSP-64-16-Rev.1 on the draft 04 series of amendments to UN Regulation No. 129 (ECE/TRANS/WP.29/GRSP/2018/29 complemented by GRSP-64-15) aimed at including in the scope of the UN Regulation:

  1. non-integral Universal ECRS with no backrest (i-Size booster cushion) and
  2. non-integral Specific vehicle ECRS with no backrest (Specific vehicle booster cushion).
Moreover, the expert from CLEPA introduced a consolidated text of all the comments received (GRSP-64-43). The expert from Germany argued that the definition of i-Size was associated with an additional side-impact test to assess protection of children when the vehicle was involved in such a collision and to ensure that children under fifteen months travel in the rearward facing position. Therefore, he stated that he opposed associating the above proposed new categories of ECRS with the i-Size definition to avoid confusion among users. The expert from Japan supported the opinion of the expert from Germany. The experts from IC and EC endorsed the inclusion of such ECRS in the scope of UN Regulation No. 129 to definitively phase out UN Regulation No. 44. Finally, GRSP agreed to resume discussion on this subject at its May 2019 session. Therefore, GRSP agreed to defer the discussion on parallel amendments to other series of amendments affected by the draft 04 series of amendments (ECE/TRANS/WP.29/GRSP/2018/30, ECE/TRANS/WP.29/GRSP/2018/32 and GRSP-64-27) at its May 2019 session. Moreover, the secretariat was requested to keep GRSP-64-27 as a reference in the agenda and to distribute GRSP-64-43 with an official symbol at the next session of GRSP.
