16. GRSP resumed consideration of paragraph 5.3.8.2. of ECE/TRANS/WP.29/GRSP/2013/15, concerning exemption to the mandatory installation of an ISOFIX position anchorages in vehicles with one seat row. However, the expert from OICA showed (GRSP-55-32) differences between sport cars unfitted for the transport of children and conventional cars with one seat row. Therefore, he proposed GRSP-55-31 which introduces a geometric criteria (R- point height above the ground less than 450 mm) to exempt such sport cars. The expert from Germany raised a study reservation on this proposal. GRSP agreed to resume consideration of this subject at its December 2014 session and requested the secretariat to distribute GRSP-55-31 with an official symbol.

16. The expert from OICA introduced GRSP-54-19-Rev.2 amending ECE/TRANS/WP.29/GRSP/2013/4, aimed at introducing exemptions under certain conditions for vehicles equipped with one seating position per row. GRSP adopted ECE/TRANS/WP.29/GRSP/2013/4, as amended by Annex III to the session report and requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their June 2014 sessions as part (see. para. 15) of draft Supplement 6 to the 07 series of amendments to the UN Regulation. Finally, GRSP agreed to resume discussion on ECE/TRANS/WP.29/GRSP/2013/15 at its May 2014 session, excluding paragraph 5.3.8.8. as already agreed with ECE/TRANS/WP.29/GRSP/2013/4.

21. GRSP considered ECE/TRANS/WP.29/GRSP/2013/4 aimed at exempting vehicles with one seating position per row from ISOFIX provisions. He justified that new concepts designed for urban mobility would not technically allow the installation of ISOFIX anchorages. The proposal received comments from the German expert (GRSP-53-11) arguing that the ISOFIX system should be promoted as much as possible in a broad range of vehicle configurations. The expert from OICA argued that GRSP-53-11 would not consider the consequences of vehicle weight increase (approximately 1 kg) and national legislation in several countries that forbid the transport of children on front seats. In principle, GRSP agreed to further study the ISOFIX requirements to address new mobility solutions. Thereby, GRSP agreed to resume discussion at its December 2013 session, based on comments (i.e. list of concept vehicle configurations) provided by the IWG on child restraints systems (CRS) and from the experts of Contracting Parties to the 1958 Agreement. Moreover, the secretariat was requested to distribute GRSP-53-11 with an official symbol and to have ECE/TRANS/WP.29/GRSP/2011/9 as a reference on the agenda of the next session.
