3 Terms and definitions
The following terms and definitions apply to this document.
4.1.1 The design, manufacture, arrangement of seat belt anchorages shall meet the
following requirements:
a) Appropriate seat belts shall be able to be fitted. The seat belt anchorages
(especially in terms of strength) of the front outer seats shall be suitable for the
installation of seat belts, which have retractors and guides; except for the vehicle,
which is equipped with other types of seat belts with retractors. If the anchorage
is only suitable for some special types of seat belts, the type of such seat belts
shall be indicated in the test report.
b) There shall be no risk of slippage of the seat belt, when properly worn.
c) There shall be no risk of damage to the webbing, when the webbing comes into
contact with protruding parts on the vehicle or seat structure.
d) For the anchorage that can change the position (the anchorage is convenient for
the occupant to enter the vehicle and can restrain the occupant), the provisions in
this standard shall apply to the anchorage, when it is in an effective restraint
position.
4.1.2 All ISOFIX anchorage systems and ISOFIX top tether anchorages, which are used
for the installation of ISOFIX CRS, shall be designed, manufactured, arranged as
follows:
a) Ensure that the vehicle meets this standard, during normal use. For the anchorage
system and ISO top tether anchorage, which can be added to any vehicles, they
shall also meet this standard. At the same time, there shall be a description of the
anchorage system, in the relevant application documents.
b) The strength design of the anchorage system and the ISOFIX top tether anchorage
system shall meet the ISOFIX child restraint system, which has the quality group
0, group 0+, group I, as defined in GB 27887-2011.
4.1.3 The design and arrangement of the ISOFIX anchorage system shall meet the
following requirements:
a) There shall be two transverse horizontal rigid rods, which have a diameter of 6
mm ± 0.1 mm; the minimum effective length of the two rods is 25 mm; the two
rods are coaxial, as shown in Figure B.4 of Appendix B.
b) All ISOFIX anchorage systems, which are installed on the vehicle's seating
position, shall be located at a distance of not less than 120 mm (horizontal
measurement to the center of the rod) from point H (see Appendix C, for the
determination of point H).
c) For all ISOFIX anchorage systems, which are installed on vehicles, it shall be
ensured that the ISOFIX child restraint fixation module ISO/F2(B) or
ISO/F2X(B1), which are described in Figure B.5 or Figure B.6 of Appendix B of
GB 14166-2013, can be installed.
d) The inclination angle of the bottom surface of the fixation module ISO/F2(B) or
ISO/F2X(B1), which are defined in Figure B.5 or Figure B.6 of Appendix B of
GB 14166-2013, is as follows; the measurement of the inclination angle is relative
to the vehicle reference plane, which is defined in Figure C.3 in Appendix C:
1) Front and rear tilt angle: 15° ± 10°;
2) Left and right deviation angle: 0° ± 5°;
3) Flip angle: 0° ± 10°.
e) ISOFIX anchorage system's position shall be permanently fixed; it can also be
hidden. For concealable anchorages, it shall meet the corresponding requirements
of the ISOFIX anchorage system, during normal use.
f) For each ISOFIX lower anchorage rod (in normal use) or each permanently fixed
guide, when unobstructed by seat cushions and backrests: along the vertical
longitudinal plane, which passes through the midpoint of the rod or guide, it shall
be clearly visible, in the 30° upwards along the horizontal plane. Alternatively,
there shall be permanent markings, near each lower anchorage rod and guide on
the vehicle. Marking is selected by the manufacturer, in one of the following
forms:
1) As shown in Figure B.12 of Appendix B, it is a circular icon, which has a
diameter of not less than 13 mm; meanwhile the icon shall have a sharp
contrast with its background,; the icon shall be close to the position of the rod
of each anchorage system;
2) The height of capital letters "ISOFIX" shall not be less than 6 mm.
4.1.4 The design and arrangement of the anchorages of the ISOFIX top tether anchorage
shall meet the following requirements:
a) The car manufacturer may choose to use one of the two methods 4.1.4b) and
4.1.4c). However, the 4.1.4b) only applies when the ISOFIX position is on the
seat.
b) According to the requirements of 4.1.4d) and 4.1.4e), in the design seating
position, the distance -- between the ISOFIX top tether anchorage, which
connects the ISOFIX top tether connector, and the reference point of the shoulder
-- shall be not more than 2000 mm; meanwhile, within the shadow area, as shown
in Figure B.6 ~ Figure B.10 of Appendix B, the placement of the two-dimensional
template, as shown in Figure B.5 of Appendix B, shall be in accordance with the
following conditions:
function of the ISOFIX top tether strap;
2) The non-rigid webbing retractor or the deployable retractor shall be not less
than 65 mm, away from the torso line; the fixed rigid retractor shall be not less
than 100 mm, away from the torso line;
3) After it is installed in the state of use, carry out the test, by applying the load
to the ISOFIX top tether anchorage, as specified in 5.5. The retracting device
shall have sufficient strength.
e) The top tether fixation device can be hidden on the seat back, if it is not in the
pull-up area of the top tether strap, on the top of the seat back.
f) The anchorage of the ISOFIX top tether anchorage shall meet the requirements for
the connection size of the ISOFIX top tether hook, which is specified in Figure
B.3 of Appendix B. Space shall be provided, around the anchorage of the ISOFIX
top tether, to allow its locking and unlocking operations. For those located behind
the ISOFIX anchorage system, all anchorages, that can be used to connect the
ISOFIX top tether hook or ISOFIX top tether connector, shall take one or more
of the following measures, to avoid misuse:
1) Design all such anchorages in the area of ISOFIX top tether anchorages as
ISOFIX top tether anchorages;
2) Only use one of the symbols, as shown in Figure B.13 of Appendix B, or its
mirror-symmetrical symbol, for marking on the ISOFIX top tether anchorage;
3) An obvious mark on the anchorage, that does not meet the above two
requirements, means that it cannot be used in combination with any ISOFIX
anchorage system.
g) For each covered ISOFIX top tether anchorage, the cover shall be marked with
the symbol or mirror-symmetrical symbol, as shown in Figure B.13 of Appendix
B, meanwhile the cover shall be able to be removed, without the use of tools.
