2.1.2. Child restraints fall into four "categories":
220.127.116.11. A "universal" category for use as specified in Paragraphs 6.1.1., 18.104.22.168., and 22.214.171.124.
on most vehicle seat positions, and in particular those which have been assessed
according to Regulation No. 16, − as being compatible with such a category of child
126.96.36.199. A "restricted" category for use as specified in Paragraphs 6.1.1. and 188.8.131.52. in
designated seat positions for particular vehicle types as indicated by either the child
restraint manufacturer or the vehicle manufacturer:
184.108.40.206. A "semi-universal" category for use as specified in Paragraphs 6.1.1. and 220.127.116.11;
18.104.22.168. A "specific vehicle" category for use either;
22.214.171.124.1. On specific vehicle types, in accordance with Paragraphs 6.1.2. and 126.96.36.199.; or
188.8.131.52.2. As a "built in" child restraint.
2.8. "Strap" means a flexible component designed to transmit forces;
2.8.1. "Lap strap" means a strap which, either in the form of a complete belt or in the form of
a component of such a belt, passes across the front of, and restrains, directly or not,
the child's pelvis;
2.8.2. "Shoulder restraint" means that part of a belt which restrains the child's upper torso;
2.8.3. "Crotch strap" means a strap (or divided straps, where two or more pieces of webbing
make it) attached to the child restraint and the lap strap and is so positioned as to pass
between the child's thighs; it is designed to prevent the child sliding under the lap belt
in normal use and prevent the lap belt moving up off the pelvis in an impact.
2.8.4. "Child-restraining strap" means a strap which is a constituent part of the belt and
restrains only the body of the child;
2.8.5. "Child-restraint attachment strap" means a strap which attaches the child restraint to
the structure of the vehicle and may be a part of the vehicle-seat retaining device;
2.8.6. "Harness belt" means a belt assembly comprising a lap belt, shoulder restraints and,
where fitted, a crotch strap;
2.8.7. "Y-shaped belt" means a belt where the combination of straps is formed by a strap to

2.8.8. "Guide strap" means a strap or device which constrains the shoulder strap of the adult
seat belt in a position to suit the child and where the effective position at which the
shoulder strap changes direction can be adjusted by means of a device which can be
moved up and down the strap to locate the wearer's shoulder, and then locked into that
position. This guide strap is not meant to carry a significant part of the dynamic load. A
guide strap is considered as a part of a child restraint system and cannot be separately
approved as a child restraint system under this Regulation.
2.9. "Buckle" means a quick release device which enables the child to be held by the
restraint or the restraint by the structure of the car and can be quickly opened. The
buckle may incorporate the adjusting device;

possible to release the buckle using a sphere having a diameter of 40mm;
2.9.2. "Non-enclosed buckle release button", a buckle release button such that it shall be
possible to release the buckle using a sphere having a diameter of 40mm.
2.10. "Adjusting device" means a device enabling the restraint or its attachments to be
adjusted to the physique of the wearer, the configuration of the vehicle, or both. The
adjusting device may either be part of the buckle or be a retractor or any other part of
the safety belt;
2.10.1. "Quick adjuster" means an adjusting device which can be operated by one hand in
one smooth movement.
2.10.2. "Adjuster mounted directly on child restraint" means an adjuster for the integral
harness which is directly mounted on the child restraint, as opposed to being directly
supported by the webbing that it is designed to adjust.
2.14.4. "Anti-rotation device"
An anti-rotation device for an ISOFIX universal child restraint system consists of
the ISOFIX top-tether.
An anti-rotation device for an ISOFIX semi-universal child restraint system
consists of either a top tether, the vehicle dashboard or a support leg intended to
limit the rotation of the restraint during a frontal impact.
For ISOFIX, universal and semi-universal, child restraint systems the vehicle
seat itself does not constitute an anti-rotation device.
2.14.5. "ISOFIX top tether anchorage" means a feature fulfilling the requirements of
Regulation No. 14, such as a bar, located in a defined zone, designed to accept an
ISOFIX top tether strap connector and transfer its restraint force to the vehicle
2.15. "Forward-facing" means facing in the normal direction of travel of the vehicle.
2.16. "Rearward-facing" means facing in the direction opposite to the normal direction of
travel of the vehicle.
2.17. "Inclined position" means a special position of the chair which allows the child to
2.18. "Lying down/supine/prone position" means a position where at least the child's
head and body excluding its limbs are on a horizontal surface when at rest in the

2.23.1. The shape, dimensions and materials of the seat structure,
2.23.2. The types and dimensions of the seat-lock adjustment and locking systems, and
2.23.3. The type and dimensions of the adult safety-belt anchorage on the seat, of the seat
anchorage, and of the affected parts of the vehicle structure.
2.24. "Displacement system" means a device enabling the adult seat or one of its parts to
be displaced angularly or longitudinally, without a fixed intermediate position, to
facilitate the entry and exit of passengers and the loading and unloading of objects.
2.25. "Locking system" means a device ensuring that the adult seat and its parts are
maintained in the position of use.
2.26. "Lock-off device" is a device which locks and prevents movement of one section of
the webbing of an adult safety-belt relative to another section of the webbing of the
same belt. Such devices may act upon either diagonal or lap section or secure together
both lap and diagonal sections of the adult belt. The term covers the following classes:
2.26.1. "Class A device", a device that prevents the child pulling webbing from the retractor
through to the lap part of the belt, when the adult belt is used to restrain the child
2.26.2. "Class B device", a device that allows the retention of an applied tension in the lap
part of an adult safety-belt, when the adult belt is used to restrain the child restraint.
The device is intended to prevent webbing slipping from the retractor through the
device, which would release the tension and place the restraint in a non-optimal
2.27. "Special Needs Restraint" is a child restraint system designed for children who have
special needs as a result of either a physical or mental handicap; this device may in
particular permit additional restraining devices for any part of the child, but it shall
contain as a minimum a primary means of restraint which complies with the
requirements of this Regulation.
2.28. "ISOFIX attachment" means one of the two connections, fulfilling the requirement of
Paragraph 6.3.2. of this Regulation, extending from the ISOFIX child restraint system
structure, and compatible with an ISOFIX low anchorage.

6.1.7. In the case of rearward-facing child restraints supported by the vehicle dashboard, for
the purpose of approval to this Regulation the dashboard is assumed to be sufficiently
6.1.8. Child restraint systems of the "universal" category, except ISOFIX universal child
restraint systems, shall have a main load-bearing contact point, between the child
restraint and the adult safety-belt. This point shall not be less than 150mm from the Cr
axis when measured with the child restraint on the dynamic test bench installed in
accordance with Annex 21 to this Regulation, without a dummy. This shall apply to all
adjustment configurations. Additional alternative belt routes are allowed. Where an
alternative belt route exists, the manufacturer shall make specific reference to the
alternative route in the user instructions, as required in Paragraph 15. When tested,
using such alternative belt route(s), the restraint shall comply with all the requirements
of the Regulation with the exception of this Paragraph.
6.1.9. If the adult belt is required to secure a "universal" category child restraint, its maximum
length to be used on the dynamic test bench is defined in Annex 13 to this Regulation.
To check compliance with this requirement, the child restraint shall be secured onto the
test bench using the appropriate standard seat belt described in Annex 13. The dummy
shall not be installed unless the design of the restraint is such that the installation of a
dummy would increase the amount of belt used. With the child restraint in the installed
position there shall be no tension in the belt apart from that exerted by the standard
retractor, where fitted. Where the retractor belt is used, this condition shall be met with
at least 150mm of belt remaining on the spool.
6.1.10. Child restraints of Groups 0 and 0+ shall not be used forward facing.
6.1.11. Child restraint systems of Groups 0 and 0+, with the exception of carry-cots as defined

the child's head in the event of a collision.
18.104.22.168. Y-shaped belts may only be used in rearward facing and lateral facing child restraint
6.2.5. The child restraint shall be so designed and installed as:
22.214.171.124. To minimize the danger of injury to the child or to other occupants of the vehicle
through sharp edges or protrusions (as defined in Regulation No. 21, for example);
126.96.36.199. Not to exhibit sharp edges or protrusions liable to cause damage to vehicle-seat covers
or to occupant's clothing;
188.8.131.52. Not to subject weak parts of the child's body (abdomen, crotch, etc.) to supplementary
inertial forces it sets up;
184.108.40.206. To ensure that its rigid parts do not, at points where they are in contact with straps,
exhibit sharp edges capable of abrading the straps.
6.2.6. Any part made separable to enable components to be fixed and detached shall be so
designed as to avoid any risk of incorrect assembly and use so far as possible.
"Special Needs Restraints" may have additional restraining devices; these shall be
designed to avoid any risk of incorrect assembly and that their means of release and
mode of operation is immediately obvious to a rescuer in an emergency.
6.2.7. Where the child restraint intended for Group I, Group II and Groups I and II combined
includes a chair back, the internal height of the latter, determined in accordance with
the diagram in Annex 12, shall be not less than 500mm.
6.2.8. Only automatically-locking retractors or emergency-locking retractors may be used.
6.2.9. For devices intended for use in Group I it shall not be possible for the child to easily
slacken that part of the system that restrains the pelvis after the child has been
installed; for this purpose the requirements of Paragraph 7.2.5. (lock-off devices) shall
be fulfilled; any device that is designed to obtain this shall be permanently attached to
the child restraint system.
6.2.10. A child restraint may be designed for use in more than one mass group and/or by more
than one child, provided that it is able to satisfy the requirements laid down for each of
the groups concerned. A child restraint in the "universal" category shall meet the
requirements of that category for all mass groups for which it has been approved.
6.2.11. Child Restraints with Retractor
In the case of a child restraint incorporating a retractor, the retractor shall have met the
requirements of Paragraph 7.2.3. below.
6.2.12. In case of booster cushions, the ease with which the straps and tongue of an adult belt
pass through the fixture points shall be examined. This goes particularly for booster
cushions which are designed for the front seats of cars, which may have long semi-rigid
stalks. The fixed buckle should not be allowed to pass through the fixture points of
booster seats, or to permit a lie of belt completely different from that of the test-trolley.

Paragraph 8.1.3. below.
18.104.22.168.1. Child restraints of the "universal", "restricted" and "semi-universal" categories shall be
tested on the test trolley by means of the test seat prescribed in Paragraph 6., and in
conformity with Paragraph 22.214.171.124.
126.96.36.199.2. Child restraints of the "specific vehicle" category shall be tested with each vehicle
model for which the child restraint is intended. The Technical Service responsible for
conducting the test may reduce the number of vehicle models tested if they do not
differ greatly in the aspects listed in Paragraph 188.8.131.52.2.3. The child restraint may be
tested in one of the following ways:
184.108.40.206.2.1. On a complete vehicle, as prescribed in Paragraph 220.127.116.11.;
18.104.22.168.2.2. In a vehicle body shell on the test trolley, as prescribed in Paragraph 22.214.171.124.; or,
126.96.36.199.2.3. In sufficient parts of the vehicle bodyshell to be representative of the vehicle structure
and impact surfaces. If the child restraint is intended for use in the rear seat, these shall
include the back of the front seat, the rear seat, the floor pan, the B and C pillars and
the roof. If the child restraint is intended for use in the front seat, the parts shall include
the dashboard, the A pillars, the windscreen, any levers or knobs installed in the floor
or on a console, the front seat, the floor pan and the roof. Furthermore, if the child
restraint is intended for use in combination with the adult safety belt, the parts shall
include the appropriate adult belt(s). The Technical Service responsible for conducting
the test may permit items to be excluded if they are found to be superfluous. Testing
shall be as prescribed in Paragraph 188.8.131.52.
184.108.40.206.3. The dynamic test shall be performed on child restraints which have not previously been
220.127.116.11.4. During the dynamic tests, no part of the child restraint actually helping to keep the child
in position shall break, and no buckles or locking system or displacement system or
support leg shall break or release or collapse, except where identified as a load limiting
device. Any load limiting device shall be clearly identified in the manufacturer's
technical descriptions as defined in Paragraph 3.2.1. of this Regulation..
18.104.22.168.5. In the case of "non-integral type" the seat belt used shall be the standard belt and its
anchorage brackets prescribed in Annex 13 to this Regulation. This does not apply to
"specific vehicle" approvals where the actual belt of the vehicle shall be used.
22.214.171.124.6. If a "specific vehicle" child restraint system is installed in the area behind the rearmost
forward facing adult seat positions (for example, the luggage area), one test with the
largest dummy/dummies on a complete vehicle as prescribed in Paragraph 126.96.36.199.3.
shall be performed. The other tests, including the conformity of production, may be
done as prescribed in Paragraph 188.8.131.52., if the manufacturer so wishes.
184.108.40.206.7. In the case of a "Special Needs Restraint" every dynamic test specified by this
Regulation for each mass group shall be performed twice: first, using the primary
means of restraint and second, with all restraining devices in use. In these tests,
special attention shall be given to the requirements in Paragraphs 6.2.3. and 6.2.4.
220.127.116.11. Chest Acceleration
18.104.22.168.1. The resultant chest acceleration shall not exceed 55g except during periods whose
sum does not exceed 3ms.
22.214.171.124.2. The vertical component of the acceleration from the abdomen towards the head shall
not exceed 30g except during periods whose sum does not exceed 3ms.
126.96.36.199. Abdominal Penetration
188.8.131.52.1. During the verification described in Annex 8 − Appendix 1, Paragraph 5.3., there shall
be no visible signs of penetration of the modelling clay of the abdomen caused by any
part of the restraining device.
184.108.40.206. Manikin Displacement

movement of the wearer the belt shall either remain in its initial position or return to that
position automatically on subsequent forward movement of the wearer.
22.214.171.124.2. If the retractor is part of a lap belt, the retracting force of the strap shall be not less than
7N as measured in the free length between the manikin and the retractor as prescribed
in Paragraph 126.96.36.199. below. If the retractor is part of a chest restraint, the retracting
force of the strap shall be not less than 2N or more than 7N as similarly measured. If
the strap passes through a guide or pulley, the retracting force shall be measured in the
free length between the manikin and the guide or pulley. If the assembly incorporates a
device, manually or automatically operated, that prevents the strap from being
completely retracted, that device shall not be in operation when these measurements

Typical Standard Anchorage Plate
Stopping of the rig during the overturning is not allowed.
The paragraph aims to ensure that the CRS will sustain all imposed loads during the dynamic test,
keeping the child in position, by maintaining the original position and configuration. Any change in the
original configuration, including change in the reclining position or in the support leg length shall be
considered a failure. Any load bearing part or component failure, like adult safety belt contact points
(identified as a belt route), anti-rotation device or CRS chair shell shall be considered a failure, except
where such behaviour is clearly identified as load limiting device function.
Completely recessed means that with the leg in the stowed position, no part of the leg protrudes beyond
the surface of the base or shell, such that it has no effect on the position of the CRS on the test bench.
See the following figures for clarification examples.
Examples of Completely Recessed Support Leg
Examples of not Completely Recessed Support Leg
"Having regard to normal conditions of use" means that this test should be performed with the restraint
mounted on the test or vehicle seat but without the dummy.
The dummy shall be used only to position the adjusting device. In the first instance the straps should be
adjusted in accordance with Paragraphs 184.108.40.206.3.2. or 220.127.116.11.3.3. (whichever is appropriate). The test
should then be conducted after removal of the dummy.
This Paragraph shall not apply to guide straps which are approved separately under this Regulation.
10.1.3. In the case of extensions where the modifications affect only one CRS group, perform
extension test only for that group, and if the excursion result is worse than for the previous
worst case for the CRS (from any group from the original approval or previous extensions)
then conduct new production qualification tests. If the head excursion is no worse than any
other previous approval or extension testing (excluding PQ tests) further production
qualification testing is not required.
In cases where the extension modifications affect more than one group, for example if
extending a group 2/3 CRS to add group 1, but the modification can affect group 2/3 (e.g.:
strengthening), than perform group 1 tests and the worst case group 2/3 (original approval).
If any result is worse than the original approval or previous extension (excluding PQ tests)
then perform production qualification tests on the new worst case.
Always compare to the worst case from all approval and extension testing (excluding any
2. TEST FREQUENCY AND RESULTS
2.1. The frequency of testing to the requirements of Paragraphs 1.1. to 1.5. and 1.7. shall be on a
statistically controlled and random basis in accordance with one of the regular quality
assurance procedure, and shall be conducted at least once per year.
2.2. Minimum conditions for the control of conformity of child restraint systems of categories
"Universal", "Semi Universal" and "Restricted", in relation to the dynamic tests according to
In accordance with the relevant authorities, the holder of an approval will supervise the control
of conformity following the method of batch control (Paragraph 2.2.1.) or following the method
of continuous control (Paragraph 2.2.2.).
2.2.1. Batch control for the child restraint systems
18.104.22.168. The holder of an approval shall divide the child restraint systems into batches which are as
uniform as possible in regard to raw material or intermediate products involved in their
manufacture (different colour of shell, different manufacture of harness) and in regard to
production conditions. The numbers in a batch shall not exceed 5,000 units.
In agreement with the relevant authorities the tests can be carried out by the Technical
Service authorities or under the responsibility of the holder of an approval.
22.214.171.124. A sample shall be taken in each batch in accordance with the provisions of Paragraph 126.96.36.199.
from a minimum of 20% of the batch quantity, which has to be produced of the actual batch.
188.8.131.52. The characteristics of the child restraint systems and the number of dynamic tests to be
conducted are given in Paragraph 184.108.40.206.
2.2.2. Continuous Control
220.127.116.11. The holder of an approval shall be obliged to carry out continuous quality control of his
manufacturing process on a statistical basis and by sampling. In agreement with the relevant
authorities, the tests can be carried out by the Technical Service authorities or under the
responsibility of the holder of an approval which is responsible for the traceability of the
18.104.22.168. The samples shall be taken in accordance with the provisions of Paragraph 22.214.171.124.
126.96.36.199. The characteristic of the child restraint systems is taken at random and the tests to be carried
out are described in Paragraph 188.8.131.52.
184.108.40.206. Control shall meet the following requirements.
Child restraint systems taken
0.02% means one child restraint system taken from every
0.05% means one child restraint system taken from every
Degree of control rigour
This dual sampling plan functions as follows:
If the child restraint system is considered to conform, the production conforms.
If the child restraint system does not meet the requirements, a second child restraint system
shall be taken,
If the second child restraint system meet the requirements, the production conforms,
If both (the first and the second) child restraint systems do not meet the requirements, the
production does not conform and child restraint systems that are likely to present the same
failure shall be withdrawn and necessary steps shall be taken to re-establish the conformity of
Strengthened control will replace normal control if, out of 10,000 child restraint systems
manufactured consecutively, the production has to be withdrawn twice.
Normal control is resumed if 10,000 child restraint systems manufactured consecutively are
considered to conform.
If production subjected to the strengthened control has been withdrawn on two consecutive
occasions, the provisions of Paragraph 13. are applied.
220.127.116.11. The continuous control of child restraint systems is undertaken starting after the production
18.104.22.168. The test results described in Paragraph 22.214.171.124. shall not exceed L, where L is the limit value
prescribed for each approval test.

METHOD OF DEFINING HEAD IMPACT AREA OF DEVICES
WITH BACKRESTS AND FOR REARWARD-FACING DEVICES DEFINING
THE MINIMUM SIZE OF SIDE WINGS
1. Place the device on the test seat described in Annex 6. Reclinable devices shall be set in the most
upright position. Place the smallest manikin in the device in accordance with the manufacturer's
instructions. Mark a Point "A" on the backrest on the same horizontal level as the shoulder of the
smallest manikin at a Point 2 cm inside the outer edge of the arm. All internal surfaces above the
horizontal plane passing through Point A, shall be tested in accordance with Annex 17. This area
shall include the backrest and side wings, including the inner edges (zone of radius) of the side
wings. In the case of carry-cot devices where a symmetrical installation of the dummy is not
possible according to the device and manufacturer instructions, the area complying with Annex 17
shall be all internal surfaces above a Point "A", as previously defined, in the head direction, when
measured with this dummy in the carry-cot in its worst position consistent with the manufactures
instructions and the carry-cot positioned on the test bench.
If a symmetrical installation of the dummy in the carry-cot may be possible, the whole inner area
shall be comply with Annex 17.
2. For rearward-facing devices there shall be side wings with a depth of minimum 90mm measured
from the median of the surface of the backrest. These side wings shall start at the horizontal plane
passing through Point "A" and continue to the top of the seat back. Starting from a point 90mm
below the top of the seat back, the depth of the side wing may be gradually reduced.
3. The requirement in Paragraph 2. above for a minimum size of side wings does not apply to child
restraints of mass Groups II and III in the specific vehicle category to be used in the luggage area
according to Paragraph 6.1.2. of this Regulation.
TYPICAL BUCKLE STRENGTH TEST DEVICE
1.2.2. Adjust the lap portion of the reference belt to achieve a tension load of 50N ± 5N at load cell 1.
Make a chalk mark on the webbing where it passes through the simulated buckle. Whilst
maintaining the belt at this position adjust the diagonal to achieve a tension of 50N ± 5N at load
cell 2 by either locking the webbing at the child restraint webbing locker or by pulling the belt
close to the standard retractor.
1.2.3. Extract all webbing from the retractor spool and rewind with a tension in the belt of 4 ± 3N
between the retractor and pillar loop. The spool shall be locked before the dynamic test.
Conduct the dynamic crash test.
1.2.4. Before commencing the set-up, check the child restraint to determine compliance with
Paragraph 126.96.36.199. If there is a change in installation tension due to the change of angle
function, then test for the condition which creates the slackest installation, conduct the set-up
and tension in the tightest position and then reposition the child restraint to the worst case
without re-tensioning the adult belt. Conduct the dynamic test.
1.3. ISOFIX Attachment
For an ISOFIX child restraint system with adjustable position seat bight ISOFIX anchorages.
Attach the unladen ISOFIX child restraint system onto the seat bight anchorages H1-H2 in the
appropriate test position. Allow the ISOFIX child restraint latch mechanisms to pull the unladen
ISOFIX child restraint system towards the seat bight. Apply an additional force of 135 ± 15N in
a plane parallel to the test bench seat cushion surface in the direction of the seat bight to
overcome frictional forces between the ISOFIX child restraint system and the seat cushion,
assisting the self-tensioning effects of the latch mechanism. The force shall be applied on or
equally about the centerline of the ISOFIX child restraint and at a height not more than 100mm
above the test bench cushion surface. If needed, adjust the top tether to achieve a tension load
of 50 ± 5N. Place appropriate test dummy in child restraint when the ISOFIX child restraint
system has been so adjusted.
