128. The Chair of the informal group on Phase II of UN GTR No. 7, introduced the third status report of the informal group (WP.29-155-40). He reported that the group had met seven times and that the last meeting was held in Washington, D.C. on 10 June 2011. He informed that the group had been addressing the head restraint height issue in two parts: (i) the procedure for measuring and determining effective height of the head restraint rather than physical height, and (ii) recommendations for the height requirement. He said good progress has been made on evaluating the rear impact dummy (BIORID II) device, although he explained that an issue relating reproducibility has been highlighted and that this was currently being investigated further. Notwithstanding unforeseeable delays, he underlined that the group had still been working to provide recommendations to GRSP at its 2012 sessions. He concluded that the next meetings of the informal group were scheduled in Geneva on 5-6 December 2011, prior to the GRSP session and in London during the week beginning 19 March 2012, in conjunction with the informal groups on harmonization of side impact dummies and Pole Side Impact. AC.3 requested the secretariat to distribute WP.29-155-40 with an official symbol.
