SCOPE
1.1.
This Regulation applies to child restraint systems which are suitable for
installation in power-driven vehicles having three or more wheels, and which are
not intended for use with folding (tip-up) or with side-facing seats.

DEFINITIONS
For the purpose of this Regulation:
2.1
Child restraint system ("restraint") means an arrangement of components which
may comprise the combination of straps or flexible components with a securing
buckle, adjusting devices, attachments and in some cases a supplementary
device as a carry-cot, infant carrier, a supplementary chair and/or an impact
shield, capable of being anchored to a power-driven vehicle. It is so designed as
to diminish the risk of injury to the wearer, in the event of a collision or of
abrupt deceleration of the vehicle, by limiting the mobility of the wearer's body.
"ISOFIX" is a system for the connection of child restraint systems to vehicles
which has two vehicle rigid anchorages, two corresponding rigid attachments on
the child restraint system and a mean to limit the pitch rotation of the child
restraint system.
2.1.1.
Child restraints fall into five "mass groups":
2.1.1.1.
group 0 for children of a mass less than 10 kg;
2.1.1.2.
group 0+ for children of a mass less than 13 kg;
2.1.1.3.
group I for children of mass from 9 kg to 18 kg;
2.1.1.4.
group II for children of mass from 15 kg to 25 kg;
2.1.1.5.
group III for children of mass from 22 kg to 36 kg.
2.1.1.6
ISOFIX Child restraint systems fall into 7 ISOFIX size classes described in
Regulation No. 16 Annex 17, Appendix 2:

assessed according to Regulation No. 16, - as being compatible with such a
category of child restraint.
2.1.2.2.
a "restricted" category for use as specified in paragraphs 6.1.1. and 6.1.3.1. in
designated seat positions for particular vehicle types as indicated by either the
child restraint manufacturer or the vehicle manufacturer:
2.1.2.3.
a "semi-universal" category for use as specified in paragraphs 6.1.1. and 6.1.3.2;
2.1.2.4.
a "specific vehicle" category for use either;
2.1.2.4.1.
on specific vehicle types, in accordance with paragraphs 6.1.2. and 6.1.3.3.; or
2.1.2.4.2.
as a "built in" child restraint.
2.1.3.
The retention system of child restraint systems may be of two classes:
an integral class if the retention of the child within the restraint system is
independent of any means directly connected to the vehicle;
a non-integral class if the retention of the child within the restraint system is
dependent upon any means directly connected to the vehicle;

the pelvis in either the 9 kg or the 15 kg dummy.
6.2.2.
For groups I, II and III, all restraint devices utilizing a "lap strap" must
positively guide the "lap strap" to ensure that the loads transmitted by the "lap
strap" are transmitted through the pelvis.
6.2.3.
All straps of the restraint shall be so placed that they cannot cause discomfort to
the wearer in normal use or assume a dangerous configuration. The distance
between the shoulder-straps in the vicinity of the neck should be at least the
width of the neck of the appropriate manikin.
6.2.4.
The assembly shall not subject weak parts of the child's body (abdomen, crotch,
etc.) to excessive stresses. The design shall be such that compression loads shall
not be imposed on the crown of the child's head in the event of a collision.
6.2.4.1.
Y-shaped belts may only be used in rearward facing and lateral facing child
restraint systems (carrycots).
6.2.5.
The child restraint shall be so designed and installed as:

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 500 mm.
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 must 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 must 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
must 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 must 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.
6.2.13.
If the child restraint is designed for more than one child, each restraint system
shall be fully independent with regard to load transfer and adjustments.
6.2.14.
The child restraints incorporating inflatable elements shall be so designed that
the conditions of use (pressure, temperature, humidity) have no influence on
their ability to comply with the requirements of this Regulation.

3.1.7.1.
The seat foam cushion is produced out of a square foam block
(800 x 575 x 135 mm) in such a way (see Figure 1 of Appendix 1 to this annex)
that its shape resembles the shape of the aluminium bottom-plate specified in
Figure 2 of Appendix 1 to this annex.
3.1.7.2.
Six holes are drilled in the bottom-plate in order to fasten it to the trolley with
bolts. The holes are drilled alongside the longest side of the plate, three on each
side, their position being dependent on the construction of the trolley. Six bolts
are put through the holes. It is recommended to glue the bolts on the plate with
an appropriate adhesive. Afterwards, the bolts are fastened with nuts.
3.1.7.3.
The cover material (1250 x 1200 mm, see Figure 3 of Appendix 1 to this annex)
is cut across the width in such a way that it is not possible for the material to
overlap after covering. There should be a gap of about 100 mm between the
edges of the cover material. Therefore the material has to be cut at about
1200 mm.

Details of materials used in this process can be obtained from TNO (Research Institute for
Road Vehicles), Schoemakerstraat 97, 2628 VK Delft, The Netherlands.

The cover material is marked with two lines which run across the width. They
are drawn 375 mm from the centreline of the cover material. (See Figure 3 of
Appendix 1 to this annex)
3.1.7.5.
The seat foam cushion is placed upside down on the cover material with the
aluminium bottom-plate on top.
3.1.7.6.
On both sides the cover material is stretched until the lines drawn on it match the
edges of the aluminium bottom-plate. At each bolt position, small incisions are
made and the cover material is pulled over the bolts.
3.1.7.7.
At the position of the grooves in the bottom-plate and in the foam, the cover
material should be incised.
3.1.7.8.
The cover is glued to the aluminium plate with a flexible glue. The nuts have to
be removed before gluing.
3.1.7.9.
The flaps on the side are folded onto the plate and are glued as well.
3.1.7.10.
The flaps in the grooves are folded inside and taped with a strong tape.
3.1.7.11.
The flexible glue has to dry for at least 12 hours.
3.1.7.12.
The seat back cushion is covered in exactly the same way as the seat, only the
lines on the cover material (1250 x 850 mm) are drawn 320 mm apart from the
centreline of the material.
3.1.8.
Line Cr is coincident with the intersection line between the top plane of the seat

Assembly of the manikin
2.6.1.
Neck-chest-pelvis
2.6.1.1.
The lumbar vertebrae and the pelvis are threaded on to the steel cable and their
tension is adjusted by a nut. The neck vertebrae are mounted and adjusted in the
same way. Since the steel cable must not be free to move through the chest, it
must not be possible to adjust the tension of lumbar vertebrae from the neck or
vice-versa.
2.6.2.
Head-neck
2.6.2.1.
The head may be mounted and adjusted by means of a bolt and nut through the

1.
Shoulder stiffness
1.1.
Place manikin on its back on a horizontal surface and support torso on one side,
to prevent movement. (Figure 2)
1.2.
Apply a load of 150 N, on a 40 mm diameter flat faced plunger, horizontally, in
a direction perpendicular to the manikin's superior-inferior axis. The axis of the
plunger should be in the centre of the manikin's shoulder and adjacent to point A
on the shoulder (see Figure 2). The lateral deflection of the plunger from the
point of first contact with the arm should be between 30 mm and 50 mm.
1.3.
Repeat on the opposite shoulder - reversing the support.
2.
Leg joint stiffness
2.1.
Place manikin on its back on a horizontal plane (Figure 3) and strap the two
lower legs together, bringing the inside of the knee into contact.
2.2.
Apply a vertical load over the knees with a 35 mm x 95 mm flat faced plunger
with the centre line of the plunger over the highest point of the knees.
2.3.
Apply sufficient force to the plunger to bend the hips until the face of the
plunger is 85 mm above the support plane. This force should be between 30 N
and 70 N. Ensure lower limbs do not contact any surface during the test.
3.
Temperature
Calibration should be carried out of a temperature between 15°C and 30°C.

EXPLANATORY NOTES
The explanatory notes given in this annex concern interpretation difficulties with the Regulation.
They are meant as a guide for the Technical Services performing the tests.
Paragraph 2.10.1.
A quick adjuster can also be a device with a rotation shaft and spring similar to a
retractor with a manual release. The adjuster should be tested to the
requirements of paragraphs 7.2.2.5. and 7.2.3.1.3.
Paragraph 2.19.2.
A semi-universal restraint specified for fitting to the rear seat in both a saloon
and an estate type vehicle in which the whole belt assembly is identical is one
"type".
Paragraph 2.19.3.
The significance of changes in the dimensions and/or mass of the seat, padding
or impact shield and the energy-absorbing characteristics or colour of the
material are to be considered when deciding whether a new type has been
created.
Paragraphs 2.19.4. and 2.19.5.
These paragraphs shall not apply to any safety belts separately approved in
accordance with Regulation No. 16 which is necessary to anchor the child
restraint to the vehicle or to restrain the child.
Paragraph 6.1.2.
For rearward-facing child restraints the correct position of the top of the restraint
relative to the child dummy head is ensured by installing the largest dummy, for
which the device was specified, in the most reclined configuration, and making
sure that a horizontal line at the eye height passes below the top of the seat.
Paragraph 6.1.8.
The 150 mm requirement also applies to carry cots.

E/ECE/TRANS/505
Regulation No. 44
page 155
Annex 15
}
Rev.1/Add.43/Rev.2
Paragraph 6.2.4.
The limit of acceptable movement of the shoulder belt is that the lower edge of
the shoulder portion of the standard safety-belt shall not be lower than the
dummy’s elbow at the point of maximum excursion of the dummy.
Paragraph 6.2.9.
Common understanding is that it applies also to devices that have such a lock-off
even if they are not required for that group. Thus the test would be applied to a
group 2 only device, but at the prescribed force, i.e. twice the mass of group 1
dummy.
Paragraph 7.1.2.1. and Annexes 17 and 18
Either energy absorbing material, or the integral material of the child restraint
structure can be tested for compliance with Annexes 17 and 18, where the
structure is not homogeneous, or if there is likely to be varying performance
over the child restraint system structure, the testing organization will determine
the worst case for testing compliance. The energy absorbing material may form
the whole or part of the child restraint system cover.
Paragraph 7.1.3.
The overturning test will be conducted using the same installation procedure and
parameters as those defined for the dynamic test.
Paragraph 7.1.3.1.
Stopping of the rig during the overturning is not allowed.
Paragraph 7.1.4.2.2.
The wording of this paragraph refers to accelerations representing tensile loads
in the spine of the dummy.
Paragraph 7.1.4.3.1.
Visible signs of penetration means penetration of the clay by the abdominal
insert (under pressure from the restraint) but not bending of the clay without
compression in a horizontal direction as for instance is brought about by simple
bending of the spine. See also interpretation of paragraph 6.2.4.

Paragraph 7.2.1.5.
The first sentence is complied with if the hand of the dummy could reach the
buckle.
Paragraph 7.2.2.1.
This shall be used to ensure that separately approved guide-straps shall be easily
attached and detached.
Paragraph 7.2.4.1.1.
Two straps are required. Measure the breaking load of the first strap. Measure
the width of the second strap at 75 percent of this load.
Paragraph 7.2.4.4.
Items which may be disassembled or unthreaded and where incorrect reassembly
is probable for an untrained user and could result in a dangerous configuration
shall not be allowed.
Paragraph 8.1.2.2.
"Fastened to the seat" means the test seat as prescribed in Annex 6. "Specific
devices may" means that a 'specific' restraint would normally be tested for
overturning when installed in the test seat, but that testing in the vehicle seat was
allowed.
Paragraph 8.2.2.1.1.
"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 8.1.3.6.3.2.
or 8.1.3.6.3.3. (whichever is appropriate). The test should then be conducted
after removal of the dummy.
Paragraph 8.2.5.2.6.
This paragraph shall not apply to guide straps which are approved separately
under this Regulation.

For a normal control, if the first sample does not contain any defective units the batch is accepted
without testing a second sample. If it contains two defective units the batch is rejected. Finally,
if it contains one defective unit a second sample is extracted and it is the cumulative number,
which must satisfy the condition of column 5 of the table above.
There is a change from normal control to strengthened control if, out of 5 consecutive batches,
two are rejected. Normal control is resumed if 5 consecutive batches are accepted.
If any batch is rejected, the production is considered to be non-conforming and the batch shall
not be released.
If two consecutive batches subjected to the strengthened control are rejected, the provisions of

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 comprise special energyabsorbing material tested in accordance with Annex 17. This material shall
cover the internal surfaces of the backrest and side wings, including the inner
edges (zone of radius) of the side wings. The energy absorbing material may be
an integral part of the child seat. 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 lower limit of area at which material
complying with Annex 17 shall be used, shall be all areas beyond dummy's
shoulder 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 surfaces shall be covered with material complying with Annex 17;
this material has to fulfill its purpose together with the inner side structure; the
Technical Service may assess this aspect with further tests.
2.
For rearward-facing devices there shall be side wings with a depth of minimum
90 mm 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 90 mm 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.

1.
Method
1.1.
Lap Belt Only
Fit load cell 1 to the outboard position as shown above. Install the child restraint
and tension the reference belt at the outboard position to achieve a load of
75N ± 5N at the outboard position.
1.2.
Lap and Diagonal Belt
1.2.1.
Fit load cell 1 to the outboard position as shown above. Install the child restraint
into the correct position. If a lock-off device is fitted to the child restraint and
acts upon the diagonal belt, place load cell 2 at a convenient position behind the
child restraint between the lock-off device and the buckle as shown above. If no
lock-off device is fitted or if the lock-off device is fitted at the buckle, position
load cell at a convenient position between the pillar loop and the child restraint.
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 ± 3 N 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 6.2.1.3. 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 ± 15 N 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 100 mm above the test bench cushion
surface. If needed, adjust the top tether to achieve a tension load of 50 ± 5 N. */
Place appropriate test dummy in child restraint when the ISOFIX child restraint
system has been so adjusted.
NOTE
1.
Installation is conducted after fitting the manikin into the restraint, for
paragraphs 1.1. and 1.2.
2.
Because the foam test cushion will compress after installation of the child
restraint, the dynamic test must be conducted no more than 10 minutes after
*/
In the case of restraints fitted with devices intended to increase the top tether tension, the
test method shall be:
Install the ISOFIX child restraint system as required in this annex and then apply the tensioner
device as stated in the manufacturers instructions. If the device cannot be applied due to excess
tension then it is deemed to be an unacceptable device.

installation as possible. To allow the cushion to recover, the minimum period
between two tests using the same cushion shall be 20 minutes.
3.
Load cells fitted directly onto the belt webbing may be disconnected electrically,
but must be left in place during the dynamic test. The mass of each cell is not to
exceed 250 grams. Alternatively the lap belt webbing load cell may be replaced
by a load cell fixed at the anchorage point.
4.
In the case of restraints fitted with devices intended to increase the adult safetybelt tension, the test method shall be:
Install the child restraint system as required in this annex and then apply the
tensioner device as stated in the manufacturers instructions. If the device cannot
be applied due to excess tension then it is deemed to be an unacceptable device.
5.
No additional force shall be applied to the child restraint system other than the
minimum required to achieve the correct installation forces as specified in
paragraphs 1.1. and 1.2.2.
6.
In case of carrycot installed as described in paragraph 8.1.3.5.6., the connection
between the adult safety belt and the restraint shall be simulated. A 500 mm free
end length adult safety belt (measured as described in Annex 13) is connected by
the anchoring plate described in Annex 13 to the prescribed anchoring points.
The restraint is then connected to the free end adult safety belts. The tension on
the adult safety belt, measured between the anchoring point and the restraint
shall be 50 ± 5 N.
