or be so designed that the manual adjusting device is readily accessible to the wearer when seated and is convenient and easy to use. It shall also be possible for it to be tightened with one hand to suit the build of the wearer and the position of the vehicle seat.
              8.3.4. Safety-belts or restraint systems incorporating retractors shall be so installed that the retractors are able to operate correctly and stow the strap efficiently. In case of both a belt adjusting device for height as well as a flexible shoulder adjustment device for height, in at least its highest and its lowest position, checks shall be made that the retractor automatically adjusts the strap to the shoulder of the concerned wearer after buckling, as well as that the tongue-plate rolls up in case of an unbuckling.
              8.3.5. In order to inform the vehicle user(s) of the provisions made for the transport of children, vehicles of categories M1, M2, M3 and N1 shall meet the information requirements of Annex 17. Any vehicle of category M1 shall be equipped with ISOFIX positions, in accordance with the relevant prescriptions of Regulation No. 14.
               The first ISOFIX position shall allow at least the installation of one out of the three forward-facing fixtures as defined in Appendix 2 of Annex 17; the second ISOFIX position shall allow at least the installation of one out of the three rear-facing fixtures as defined in Appendix 2 of Annex 17. For this second ISOFIX position, in case where the installation of the rear-facing fixture is not possible on the second row of seats of the vehicle due to its design, the installation of one out of the six fixtures is allowed in any position of the vehicle.
              8.3.6. Any i-Size seating position shall allow the installation of the ISOFIX child restraint fixtures "ISO/F2X" (B1), "ISO/R2" (D) and the support leg installation assessment volume as defined in Appendix 2 to Annex 17.

               The support leg installation assessment volume is characterized as follows (see also Annex 17, Appendix 2, Figures 8 and 9, to this Regulation):

               (a) Lateral limitation:

                   By two planes parallel to and 100 mm apart from the median longitudinal plane of the child restraint fixture installed in the respective seating position;

               (b) Forward limitation:

                  By a plane perpendicular to the plane given by the child restraint fixture bottom surface and perpendicular to the median longitudinal plane of the child restraint fixture, 695 mm apart from the plane passing through the centerlines of the ISOFIX lower anchorages and being perpendicular to the CRF bottom surface;

              (c) Rearward limitation:

                     (i) Above the level of the bottom surface of the child restraint fixture by the front surface of the
