Proposal to amend the regulation frontal impacts with a view towards the establishment of a new regulation on frontal impact testing for occupant restraint systems (full width rigid barrier test). The proposal increases the thorax compression criterion (ThCC) stringency to 42 mm (from 50 mm).
26. The expert from France, Chair of the frontal impact (FI) IWG, introduced ECE/TRANS/WP.29/GRSP/2015/7 to align the UN Regulation No. 94 with the provisions of new draft UN Regulation (full-width frontal collision) on the protection of older occupants. GRSP adopted ECE/TRANS/WP.29/GRSP/2015/7, as amended by Annex III (including GRSP-57-02) to this report. The secretariat was requested to submit ECE/TRANS/WP.29/GRSP/2015/7 as amended to WP.29 and AC.1, for consideration and vote at their November 2015 sessions as draft 03 series of amendment to UN Regulation No. 94.
