systems, design and positioning:

5.2.3.1.                   Any ISOFIX anchorages system shall be 6 mm 0.1 mm diameter transverse horizontal rigid bar(s) which cover(s) two zones of 25 mm minimum effective length located on the same axis as defined in figure 4 annex 9.

5.2.3.2.                   Any ISOFIX anchorages system installed on a vehicle seating position shall be located not less than 120 mm behind the design H-point as determined in annex 4 to this Regulation, measured horizontally and up to the centre of the bar.

5.2.3.3.                   For any ISOFIX anchorages system installed in the vehicle, it shall be verified the possibility to attach the ISOFIX child restraint fixture "ISO/F2" (B) described in Regulation No. 16 (annex 17, appendix 2, figure 2).

         5.2.3.4.                  The bottom surface of the fixture "ISO/F2" (B) as defined in Regulation No. 16 (annex 17, appendix 2, figure 2), shall have attitude angles within the following limits, angles measured relatively to the vehicle reference planes as defined in annex 4 appendix 2 to this Regulation:

Pitch: 15° 10°,

Roll: 0° 5°,

Yaw: 0° 10°

5.2.3.5.                   ISOFIX anchorage systems shall be permanently in position or storable. In case of storable anchorages, the requirements relating to ISOFIX anchorages system shall be fulfilled in the deployed position.

         5.2.3.6.                   Each ISOFIX low anchorage bar (when deployed for use) or each permanently installed guidance device shall be visible, without the compression of the seat cushion or seat back, when the bar or the guidance device is viewed, in a vertical longitudinal plane passing through the centre of the bar or of the guidance device, along a line making an upward angle of 30 degrees with a horizontal plane.

As an alternative to the above requirement, the vehicle shall be permanently marked adjacent to each bar or guidance device. This marking shall consist in one of the following, at the choice of the manufacturer.

         5.2.3.6.1.            As a minimum, the symbol of annex 9, figure 12 consisting of a circle with a diameter of minimum 13 mm and containing a pictogram, meeting the following conditions:

              a)                    the pictogram shall contrast with the background of the circle;

              b)                   the pictogram shall be located close to each bar of the system;

         5.2.3.6.2.            The word "ISOFIX" in capital letters of at least 6 mm height.
5.2.4.                         ISOFIX top tether anchorages, design and positioning:

At the request of the car manufacturer, methods described in paragraphs 5.2.4.1. and 5.2.4.2. can be used alternatively.

Method described in paragraph 5.2.4.1. can only be used if the ISOFIX position is located on a vehicle seat.

5.2.4.1.                   Subject to paragraphs 5.2.4.3. and 5.2.4.4., the portion of each ISOFIX top tether anchorage that is designed to bind with an ISOFIX top tether connector shall be located
