point H.
c) As shown in Figure A.11, the ISOFIX low anchorage is installed in the ISOFIX
position. Utilize the fixture ISO/F2 alternative method of Figure A.5 in GB 14166-
2024 to determine the position of the top tether anchorage. The seating position shall
be with the seat adjusted to the rearmost and lowest position, and the seat back in the
normal position or the position recommended by the manufacturer. In the side view,
the ISOFIX top tether anchorage shall be behind the ISO/F2 rear surface. The
intersection point of the ISO/F2 rear surface and the horizontal line passing through
the last rigid point of the top of the seat backrest with a Shore A hardness exceeding
50 (Figure A.11) and the ISO/F2 center line is determined as datum point 4.At this
point, the maximum 45??? upward from the horizontal line is defined as the upper limit
of the top tether anchorage area. In the top view, make an area with a maximum angle
of 90??? through datum point 4 to both sides of the back. In the rear view, make an area
with a maximum angle of 40??? through datum point 4.The ISOFIX top tether
anchorage is located in the two three-dimensional areas. The starting point 5 of the
ISOFIX top tether strap is located at the intersection of a plane 550 mm upward from
plane 1 of the ISO/F2 fixture and the center line 6.Measure along the strap from the
seat back to the ISOFIX top tether anchorage, and the distance between the ISOFIX
top tether anchorage and the starting point of the ISOFIX top tether strap on the rear
surface of the ISO/F2 fixture shall be greater than 200 mm, but not greater than 2,000
mm.
d) If the ISOFIX top tether anchorage cannot be placed within the specified shadow area
and the vehicle is equipped with an ISOFIX top tether anchorage path guidance device,

2) The icon shall be located close to the rod position of each anchorages system.
b) In addition to satisfying the requirements of 4.1.3 and 4.1.4, the i-Size seating position
connected to the i-Size support leg shall also verify that both the two limit surfaces in
the X direction between the upper surface of the vehicle floor and the support leg foot
assessment volume intersect with the two limit surfaces in the Y direction, as shown
in Figure A.15 and Figure A.16.The characteristics of the support leg foot assessment
volume are as follows.
1) In the width direction, it is determined by two parallel planes respectively 100
mm apart from the longitudinal mid-plane of the child restraint fixture installed
in the seating position;
2) In the length direction, it is determined by two planes respectively perpendicular
anchorages in the outer position of the front row.
