Proposal to eliminate divergent interpretations of paragraph 6.4. with regard to the testing for head restraint performance of a bench seat with three seating positions and two head restraints. Under this condition, the proposal would require application of a moment of 3 × 373 Nm to the back of the seats and of 2 × 373 Nm to the head restraints. The manufacturer may request to apply 53 daNm to each seat back without head restraint and 89 daNm to each head restraint in order to comply with the requirements of paragraph 6.2. on the strength of the seat back during this test. If the manufacturer does not opt to apply these forces, then the test procedure specified in paragraph 6.2. must be carried out in addition to the head restraint testing under paragraph 6.4.
20. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSP/2017/12 to clarify the testing of seats with and without head restraints. Moreover, the expert from CLEPA introduced GRSP-61-26 incorporating the comments received from the experts from Germany and EC. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2017/12 as amended by Annex IV to this report. The secretariat was requested to submit the proposal as draft Supplement 4 to the 08 series of amendments to UN Regulation No. 17 for consideration and vote at the November 2017 sessions of WP.29 and AC.1.
