Working Party on Passive Safety | Session 58 | 8-11 Dec 2015
Geneva
Agenda Item 11.
UN Regulation No. 17

26. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2015/18, aimed at clarifying the provisions for dynamic testing of the rear seat restraint systems. She explained that the proposal aimed at updating requirements that were originally designed for seating positions that did not yet require three-point safety-belts; she added that the situation had developed with the introduction of load limiters that allowed for further displacement of occupants. Comments from GRSP experts on the proposal were incorporated into GRSP-58-35 during discussion. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSP/2015/27 that was also linked to ECE/TRANS/WP.29/GRSP/2015/18 because the of displacement of occupants due to safety belt load limiters that were installed on seats other than front seats. He explained that the proposal needed corresponding amendments to UN Regulations Nos. 21, 25 and 80. The expert from OICA argued that the proposal should address just those seating positions that needed energy absorption requirements. The expert from CLEPA also underlined the need to focus the energy dissipation tests on the parts of back seats where actual impacts occur.

27. Finally, GRSP agreed to establish a group of interested experts, led by the expert from the Netherlands, on new restraint system technology to develop provisions on this matter for all the relevant UN Regulations. GRSP agreed to resume discussion on this subject at its May 2016 session and to refer ECE/TRANS/WP.29/GRSP/2015/18, ECE/TRANS/WP.29/GRSP/2015/27 and GRSP-58-35 to the group of interested experts.

28. Moreover, the expert from Japan introduced GRSP-58-28-Rev.1, proposing to align UN Regulation No. 17 to the provisions of the draft UN GTR No. 7, Phase 2. GRSP agreed to keep GRSP-58-28-Rev.1 as an informal document for its May 2016 session awaiting possible updates.
