1.   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.




2.   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.

2.1.2.


Child restraints fall into four ‘categories’:












2.1.2.1.


A ‘universal’ category for use as specified in paragraphs 6.1.1., 6.1.3.1., and 6.1.3.2. on most vehicle seat positions, and in particular those which have been assessed according to UN 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.
















2.1.3.1.


‘Partial restraint’ means a device, such as a booster cushion, which, when used in conjunction with an adult seat belt, which passes around the body of the child or restrains the device in which the child is placed, forms a complete child restraint system.












2.1.3.2.


‘Booster cushion’ means a firm cushion, which can be used with an adult seat belt.












2.2.


‘Child-safety chair’ means a child restraint incorporating a chair in which the child is held.












2.3.


‘Belt’ means a child restraint comprising a combination of straps with a securing buckle, adjusting devices and attachments.












2.4.


‘Chair’ means a structure which is a constituent part of the child restraint and is intended to accommodate a child in a seated position.












2.4.1.


‘Carry cot’ means a restraint system intended to accommodate and restrain the child in a supine or prone position with the child’s spine perpendicular to the median longitudinal plane of the vehicle. It is so designed as to distribute the restraining forces over the child’s head and body excluding its limbs in the event of a collision.












2.4.2.


‘Carry-cot restraint’ means a device used to restrain a carry-cot to the structure of the vehicle.












2.4.3.


‘Infant carrier’ means a restraint system intended to accommodate the child in a rearward-facing semi-recumbent position. It is so designed as to distribute the restraining forces over the child’s head and body excluding its limbs in the event of the frontal collision.












2.5.


‘Chair support’ means that part of a child restraint by which the chair can be raised.












2.6.


‘Child support’ means that part of a child restraint by which the child can be raised within the child restraint.

If the restraint is to be used in combination with an adult safety belt the correct routing of the webbing shall be clearly indicated by means of a drawing permanently attached to the restraint. If the restraint is held in place by the adult safety-belt, the routes of the webbing shall be clearly marked on the product by colour coding. The colours for the safety-belt route to be used when the device is installed forward facing shall be red and when installed rear-facing shall be blue. Devices that can be installed rearward and forward facing without changing the belt routing (e.g. turnable system) shall use both colours. The same colours shall also be used on the labels on the device that illustrate the methods of use.
There shall be a clear differentiation between the intended routes for the lap section and the diagonal section of the safety belt. Indication such as colour coding, words, shapes, etc. shall distinguish each section of the safety belt.
In any illustration of the belt route on the product, the orientation of the child restraint relative to the vehicle shall be clearly indicated. Belt route diagrams that do not show the vehicle seat are not acceptable.
The marking defined in this paragraph shall be visible with the restraint in the vehicle. For group 0 restraints, this marking shall also be visible with the child in the restraint.












4.4.


On the visible inner surface (including the inside surface of a side wing beside the child’s head) in the approximate area where the child’s head rests within the child restraint system, rearward facing restraints shall have the shown label permanently attached.
The overall dimensions of the label shall be at least 120 × 60 mm or the equivalent area.
The label may be adapted in such a way that the layout differs from the example shown here; however, the content shall meet the precise prescriptions. Furthermore, no other type of information shall be included on the label unless it is placed outside a clearly marked rectangle with at least the overall dimensions as required above. In derogation to the aforementioned, a part number, bar code or similar identification mark not exceeding 8 mm × 35 mm or the equivalent area may be placed on the label.
It shall also be ensured that no deviations in the shape and orientation of the provided pictograms are permitted, notably that any customised appearance of the prescribed pictogram images shall be prohibited, with the exception of the hand with pointing index finger and the open face booklet with letter ‘i’ on its right page provided that they are clearly recognisable as such.
Small irregularities concerning line thickness, label imprinting and other relevant production tolerances shall be accepted.
The label shall be stitched to the cover around its entire perimeter and/or permanently bonded to the cover over its entire back surface. Any other form of attachment that is permanent and not liable to removal from the product or to becoming obscured is acceptable. Flag type labels are specifically prohibited.
If sections of the restraint or any accessories supplied by the child restraint system manufacturer are able to obscure the label an additional label is required. One warning label shall be permanently visible in all situations when the restraint is prepared for use in any configuration.



























4.5.


In the case of child restraints that can be used forward and rear-facing, include the words:

                     ‘IMPORTANT – DO NOT USE FORWARD FACING BEFORE THE CHILD’s WEIGHT EXCEEDS .......... (Refer to instructions)’.












4.6.


In the case of child restraints with alternative belt routes, the alternative load bearing contact points between the child restraint and the adult safety-belt shall be permanently marked. This marking shall indicate that it is the alternative belt route, and shall conform with the above coding requirements for forward and rearward facing seats.












4.7.


If the child restraint offers alternative load bearing contact points, the marking required in paragraph 4.3. shall include an indication that the alternative belt route is described in the instructions.

6.2.


Configuration












6.2.1.


The configuration of the restraint shall be such that:












6.2.1.1.


The restraint gives the required protection in any intended position of the restraint system; for ‘Special Needs Restraints’ the primary means of restraint shall give the required protection in any intended position of the restraint system without the use of the additional restraining devices which may be present.












6.2.1.2.


The child is easily and quickly installed and removed; in the case of a child restraint system in which the child is restrained by means of a harness belt or a Y-shaped belt without a retractor each shoulder restraint and lap strap shall be capable of movement relative to each other during the procedure prescribed in paragraph 7.2.1.4.
In these cases the belt assembly of the child restraint system may be designed with two or more connecting parts. For ‘Special Needs Restraints’ it is recognized that the additional restraining devices will restrict the speed by which a child can be installed and removed. However, the additional devices shall be designed to release quickly so far as possible.












6.2.1.3.


If it is possible to change the inclination of the restraint, this change in inclination shall not require manual readjustment of the straps. A deliberate hand-action is required in order to change the inclination of the restraint.












6.2.1.4.


The groups 0, 0+ and I restraint systems shall keep the child so positioned as to give the required protection even when the child is asleep.












6.2.1.5.


For all forward-facing group I restraints incorporating an integral harness belt system to prevent submarining, either by impact or through restlessness, a crotch strap shall be required.












6.2.2.


All restraint devices utilizing a ‘lap strap’ shall positively guide the ‘lap strap’ equilateral on both sides to ensure that the load transmitted by the ‘lap strap’ are transmitted through the pelvis. The assembly shall not subject weak parts of the child’s body (abdomen, crotch, etc.) to excessive stresses.
In the case of booster cushions and booster seats, the lap portion of the adult seat belt shall be positively guided equilateral on both sides to ensure that the loads are transmitted by the adult lap belt are transmitted through the pelvis. The positive guidance of loads over the pelvis shall be realised from the moment that the child is installed; the lap belt shall pass over the top of the thigh, just touching the fold with the pelvis. The angles α and β between the tangent line in which the belt touches the thighs and the horizontal shall be greater than 10°.

















6.2.2.1.


With the crotch strap attached and in its longest position if adjustable, it shall not be possible to adjust the lap strap to lie above the pelvis of both the smallest and largest dummy within the mass groups covered by the approval. For all forward-facing restraints, it shall not be possible to adjust the lap strap to lie above the pelvis of both the smallest and largest dummy within the mass groups covered by the approval.












6.2.2.2.


During the dynamic test, as prescribed in paragraph 8.1.3., the lap belt shall not pass fully beyond the pelvic structure of the dummy, during the period prior to maximum horizontal head excursion. Assessment shall be carried out using high speed video imaging.












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 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:












6.2.5.1.


To minimize the danger of injury to the child or to other occupants of the vehicle through sharp edges or protrusions (as defined in UN Regulation No 21, for example);












6.2.5.2.


Not to exhibit sharp edges or protrusions liable to cause damage to vehicle-seat covers or to occupant’s clothing;












6.2.5.3.


Not to subject weak parts of the child’s body (abdomen, crotch, etc.) to supplementary inertial forces it sets up;












6.2.5.4.


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 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 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.












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.

ANNEX 15
Explanatory notes
The explanatory notes given in this annex concern interpretation difficulties of some paragraphs of 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 UN 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.
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 I dummy.
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 7.1.4.1.4.
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.
Paragraph 7.1.4.1.10.1.2.
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.




Figure 1 Examples of completely recessed support leg








Figure 2 Examples of not completely recessed support leg




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 8.1.3.6.3.2.
The hinged board or similar flexible device is intended to simulate the removal of clothing from the child and a failure to re-adjust the harness system. Where the child is restrained by a system that adjusts to fit the child’s physique without external intervention (where the adult belt is used or the harness contains automatic or emergency locking retractors), it shall not be necessary to use the hinged board. For child restraint systems where the length of the straps can be fixed (for example a harness without retractors or the adult belt is used with a lock-off), the use of the hinged board is required. The hinged board must be used for the setup of CRS using belted impact shields.
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.
Paragraph 10.1.3.

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 PQ tests).

1.7.   Temperature test
According to the provisions of paragraph 7.1.5. of this Regulation.
2.   Test frequency and results








2.1.


The frequency of testing to the requirements of paragraphs 1.1. to 1.5. and 1.7. above 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 paragraph 1.6 above.
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












2.2.1.1.


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.








2.2.1.2.


A sample shall be taken in each batch in accordance with the provisions of paragraph 2.2.1.4. from a minimum of 20 percent of the batch quantity, which has to be produced of the actual batch.












2.2.1.3.


The characteristics of the child restraint systems and the number of dynamic tests to be conducted are given in paragraph 2.2.1.4.












2.2.1.4.


In order to be accepted, a batch of child restraint systems shall satisfy the following conditions:

Note:

MH signifies harder configuration (the least good results obtained in approval or extension of approval)
LH signifies a less hard configuration.




This dual sampling plan functions as follows:






 


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 shall 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 paragraph 13. are applied.
















2.2.1.5.


The control of child restraint systems conformity is undertaken starting with the batch manufactured after the first batch which was subjected to production qualification.












2.2.1.6.


The test results described in paragraph 2.2.1.4. shall not exceed L, where L is the limit value prescribed for each approval test.












2.2.2.


Continuous control












2.2.2.1.


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 product.












2.2.2.2.


The samples shall be taken in accordance with the provisions of paragraph 2.2.2.4.












2.2.2.3.


The characteristic of the child restraint systems is taken at random and the tests to be carried out are described in paragraph 2.2.2.4.












2.2.2.4.


Control shall meet the following requirements.






Child restraint systems taken


Degree of control rigour




0,02 percent means one child restraint system taken from every 5 000  manufactured


Normal




0,05 percent means one child restraint system taken from every 2 000  manufactured


Strengthened




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 the production.










 


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.
















2.2.2.5.


The continuous control of child restraint systems is undertaken starting after the production qualification.












2.2.2.6.


The test results described in paragraph 2.2.2.4. shall not exceed L, where L is the limit value prescribed for each approval test.












2.3.


For ‘built-in’ vehicle specific devices, the following test frequencies shall apply:






Child restraints, except booster cushions:


Once every 8 weeks




Booster cushions:


Once every 12 weeks




At each test all requirements according to paragraphs 7.1.4. and 7.2.1.8.1. shall be fulfilled. If all tests during one year show satisfactory results, the manufacturer may, after agreement with the Type Approval Authority, reduce the frequencies as follows:






Child restraints, except booster cushions:


Once every 16 weeks




Booster cushions:


Once every 24 weeks




However, a minimum frequency of one test per year shall be permitted where annual production is 1 000 child restraint systems or less.












2.3.1.


For vehicle-specific devices according to paragraph 2.1.2.4.1., the child restraint manufacturer may choose Conformity of Production procedures according to either paragraph 2.2. above, on a test seat, or paragraph 2.3. above, in a vehicle body shell.












2.3.2.


Where a test sample fails a particular test to which it has been subjected, a further test to the same requirement shall be carried out on at least three other samples. In the case of dynamic tests if one of the latter fails, the production is considered to be non-conforming and the frequency shall be raised to the higher one if the lower one was used according to paragraph 2.3. and necessary steps shall be taken to re-establish the conformity of the production.












2.4.


When production is found to be non-conforming according to paragraphs 2.2.1.4., 2.2.2.4. or 2.3.2., the holder of the approval or his duly accredited representative shall:












2.4.1.


Notify the Type Approval Authority which has granted type approval indicating what steps have been taken to re-establish the conformity of production.












2.5.


The manufacturer shall advise the Type Approval Authority on a quarterly basis, the volume of products produced against each approval number, providing a means of identifying which products correspond to that approval number.









ANNEX 17
Test of energy absorbing material
1.   Headform








1.1.


The headform shall consist of a solid wooden hemisphere with an added smaller spherical segment as shown in Figure A below. It shall be constructed so that it can be dropped freely along the axis marked and it shall have provision for mounting an accelerometer in order to measure the acceleration along the direction of fall.












1.2.


The headform shall have a total mass, including the accelerometer of 2,75 ±0,05 kg.








Figure A Headform




Dimensions in mm
2.   Instrumentation
The acceleration shall be recorded during the test, using equipment in accordance with channel frequency class 1 000 as specified in the latest version of ISO 6487.
3.   Procedure








3.1.


The assembled child restraint shall be placed in the region of impact on a rigid flat surface, whose minimum dimensions are 500 × 500 mm, so that the direction of impact is perpendicular to the inner surface of the child restraint system in the area of impact.












3.2.


Raise the headform to a height of 100 –0/+5 mm from the respective upper surfaces of the assembled child restraint to the lowest point on the headform, and allow it to fall. Record the acceleration experienced by the headform during impact.









ANNEX 18
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 carrycot 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 carrycot in its worst position consistent with the manufacturer instructions and the carrycot positioned on the test bench.
If a symmetrical installation of the dummy in the carrycot may be possible, the whole inner area shall comply with Annex 17.


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.







ANNEX 19
Description of conditioning of adjusters mounted directly on child restraints




Figure 1





1.   

Method



1.1.   

With the webbing set at the reference position described in paragraph 8.2.7., withdraw at least 50 mm of webbing from the integral harness by pulling on the free end of the webbing.



1.2.   

Attach the adjusted part of the integral harness to the pulling device A.



1.3.   

Activate the adjuster and pull at least 150 mm of webbing into the integral harness. This represents half of one cycle and puts pulling device A to the maximum webbing extraction position.



1.4.   

Connect free end of webbing to pulling device B.



2.   

The cycle is:



2.1.   

Pull B at least 150 mm whilst A exerts no tension on the integral harness.



2.2.   

Activate the adjusters and pull A whilst B exerts no tension on the free end of the webbing.



2.3.   

At the end of stroke, de-activate the adjuster.



2.4.   

Repeat cycle as specified in paragraph 7.2.2.7. of this Regulation.







ANNEX 20
Typical buckle strength test device










ANNEX 21
Dynamic crash test installation





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 75 N ± 5 N 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 50 N ± 5 N 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 50 N ± 5 N 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 centreline 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 shall be conducted no more than 10 minutes after 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 shall 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 safety-belt 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. above.










6.


In case of carrycot installed as described in paragraph 8.1.3.5.6. of this Regulation, 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.






(*)  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 manufacturer’s instructions. If the device cannot be applied due to excess tension then it is deemed to be an unacceptable device.

               ‘Occupant compartment air space’
             means the space within the occupant compartment that normally contains refreshable air.
2.   Material selection (see Figure 1 below)








2.1.


Any portion of a single or composite material which is within 13 mm of the occupant compartment air space shall meet the requirements in paragraph 6.1.6.












2.1.1.


Any material that does not adhere to other material(s) at every point of contact shall meet the requirements of paragraph 6.1.6. when tested separately.












2.1.2.


Any material that adheres to other materials at every point of contact shall meet the requirements of paragraph 6.1.6. when tested as a composite with the other material(s).
Material A has a non-adhering interface with material B and is tested separately.
Part of material B is within 13 mm of the occupant compartment air space, and materials B and C adhere at every point of contact; therefore, B and C are tested as a composite.
The cut is in material C as shown in Figure 1, to make a specimen 13 mm thick.

3.   Test procedure








3.1.


The test is conducted in a metal cabinet for protecting the test specimens from drafts. The interior of the cabinet is 381 mm long, 203 mm deep, and 356 mm high. It has a glass observation window in the front, a closable opening to permit insertion of the specimen holder, and a hole to accommodate tubing for a gas burner. For ventilation, it has a 13 mm clearance space around the top of the cabinet, ten holes in the base of the cabinet, each hole 19 mm in diameter and legs to elevate the bottom of the cabinet by 10 mm, all located as shown in Figure 2.












3.2.


Prior to testing, each specimen is conditioned for 24 hours at a temperature of 21 °C, and a relative humidity of 50 per cent, and the test is conducted under those ambient conditions.












3.3.


The test specimen is inserted between two matching U-shaped frames of metal stock 25 mm wide and 10 mm high.
The interior dimensions of the U-shaped frames are 51 mm wide by 330 mm long.
A specimen that softens and bends at the flaming end so as to cause erratic burning is kept horizontal by supports consisting of thin, heat-resistant wires, spanning the width of the U-shaped frame under the specimen at 25 mm intervals.
A device that may be used for supporting this type of material is an additional U-shaped frame, wider than theU-shaped frame containing the specimen, spanned by 10-mil wires of heat-resistant composition at 25 mm intervals, inserted over the bottom U-shaped frame.












3.4.


A Bunsen burner with a tube of 10 mm inside diameter is used.
The gas adjusting valve is set to provide a flame, with the tube vertical, of 38 mm in height. The air inlet to the burner is closed.












3.5.


The gas supplied to the burner has a flame temperature equivalent to that of natural gas.




4.   Preparation of specimens








4.1.


Each specimen of material to be tested shall be a rectangle 102 mm wide by 356 mm long, wherever possible.
The thickness of the specimen is that of the single or composite material used in the vehicle, except that if the material’s thickness exceeds 13 mm, the specimen is cut down to that thickness measured from the surface of the specimen closest to the occupant compartment air space.
Where it is not possible to obtain a flat specimen because of surface curvature, the specimen is cut to not more than 13 mm in thickness at any point.
The maximum available length or width of a specimen is used where either dimension is less than 356 mm or 102 mm.












4.2.


The specimen is produced by cutting the material in longitudinal as well as transverse direction.
The specimen is oriented so that the surface closest to the occupant compartment air space faces downward on the test frame.












4.3.


Material with a napped or tufted surface is placed on a flat surface and combed twice against the nap with a comb having seven to eight smooth, rounded teeth per 25 mm.




5.   Test








5.1.


Mount the specimen so that both sides and one end are held by the U-shaped frame. If the specimen is less than 51 mm, so that the sides of the specimen cannot be held in the U-shaped frame, place the specimen in position on wire supports as described in paragraph 3.3, with one end held by the closed end of the U-shaped frame.












5.2.


Place the mounted specimen in a horizontal position, in the centre of the cabinet.












5.3.


With the flame adjusted according to paragraph 3.4, position the Bunsen burner and specimen so that the centre of the burner tip is 19 mm below the centre of the bottom edge of the open end of the specimen.












5.4.


Expose the specimen to the flame for 15 seconds.












5.5.


Begin timing (without reference to the period of application of the burner flame) when the flame from the burning specimen reaches a point 38 mm from the open end of the specimen.












5.6.


Measure the time that it takes the flame to progress to a point 38 mm from the clamped end of the specimen. If the flame does not reach the specified end point, time its progress to the point where flaming stops.












5.7.


Calculate the burn rate from the formula:
B = 60 × (D/T)
Where:







B


=


Burn rate in millimetres per minute;




D


=


Length the flame travels in millimetres; and




T


=


Time in seconds for the flame to travel D millimetres.
