6.1.3.4.

Enhanced Child Restraint Systems of the booster seat and booster cushion categories shall have a main load-bearing contact point, between the Enhanced Child Restraint System and the adult safety belt. This point shall not be less than 150 mm from the Cr axis when measured with the Enhanced Child Restraint System on the dynamic test bench installed in accordance with paragraph 7.1.3.5.2.2. of this Regulation, without a dummy. This shall apply to all adjustment setups and webbing paths.

6.1.3.5.

The adult seat belt required to secure belted Enhanced Child Restraint Systems on the dynamic test bench is defined in Annex 22 to this Regulation. The Enhanced Child Restraint System shall be secured onto the test bench using the appropriate standard seat belt described in Annex 24 using a preload tension of 50N ± 5N. 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 Enhanced Child Restraint System in the installed position, there shall be no additional tension in the belt, apart from that exerted by the standard retractor (4 ± 3 N), where fitted. Where the retractor belt is used, this condition shall be met with at least 150 mm of belt remaining on the spool.

A clamping mechanism used according to paragraph 7.1.3.5.2.2. shall not have any influence on the belt path.

6.1.3.6.

For booster cushions, type approval shall not be granted for a stature below 125 cm. Booster cushions shall not be declared for use below a stature of 125 cm.

Booster cushions shall ensure that the top of the child's head is at or above a horizontal plane at 770 mm vertically from the Cr axis when seated on the test bench described in Annex 6.

The procedure to check if a booster cushion fulfils this requirement is outlined as follows (See Figure 1 below):

Image 21

(a)

A simulated test bench shall be used for the assessment. The simulated bench shall have the same geometry as the test bench defined in Annex 6 of this Regulation, including the seat cushions. However, the width of the simulated bench may be reduced, if the width is between 500 and 800 mm, as shown in Annex 25. The simulated test bench shall be of rigid construction and shall not deform when using the measuring device defined in Annex 25.

(b)

A rigid structure is attached to the simulated test bench and holds a sliding part. A horizontal plane that is located at a vertical distance of 770 mm from the Cr axis is defined.

(c)

The booster cushion shall be placed on the simulated test bench with its centreline aligned with the centreline of the test bench and the rear surface of the booster cushion contacting the backrest of the test bench.

(d)

If ISOFIX attachments are present these shall be latched with the test bench lower ISOFIX anchorages. An additional force of 135 +/-15 N shall be applied in a plane parallel to the surface of the simulated test bench. The force shall be applied along the centreline of the Enhanced Child Restraint System and at a height of no more than 100 mm above the simulated test bench seat surface.

(e)

The measurement device is extended downwards parallel to the simulated test bench backrest, until it is stopped by the booster seat cushion.

Image 22

(f)

The measured distance between the two points M and N (Figure 1) represents the sitting height of a child who will use the booster cushion. The corresponding value is displayed by a ruler that is provided with the device as shown in Figure 2.

(g)

Using the data in Table 3, the sitting height is utilized to determine the corresponding minimum stature of the child that can be accommodated by the booster cushion. Example: A sitting height of 66,2 cm shall correspond to a child minimum stature of 125 cm; a sitting height of 75,9 cm shall correspond to 150 cm.

In case the value obtained for the sitting height is between two integer values always round up to the next integer value (e.g. Measured sitting height = 70,1 cm ► resulting stature = 135,65 cm ► Smallest stature allowed = 136 cm).

(h)

The stature determined in this procedure shall be compared to the lower limit of the approval stature range. The requirement is fulfilled if the lower approval stature is greater or equal than the obtained minimum stature.

6.2.

Configuration of the Enhanced Child Restraint System

6.2.1.

The configuration of the Enhanced Child Restraint System shall be such that:

6.2.1.1.

The restraint of the child shall give the required protection in any position specified for the Enhanced Child Restraint System;

Inserts shall form only one layer on the seat surface. This does not preclude the use of additional ‘comfort’ inserts, provided they are not needed to comply with the requirements of the regulation;

For "Special Needs Restraints" the primary means of restraint shall give the required protection in any intended position of the Enhanced Child Restraint System without the use of the additional restraining devices which may be present.

6.2.1.2.

The Enhanced Child Restraint System shall be such that the child may be easily and readily restrained or removed. In the case of an Enhanced 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 6.7.1.4. below; in these cases the Enhanced Child Restraint System belt assembly 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 restrained 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 Enhanced Child Restraint System, this change in inclination shall not require manual readjustment of any other part of the Enhanced Child Restraint System. A deliberate hand-action shall be necessary in order to change the inclination of the Enhanced Child Restraint System.

During the dynamic tests, the standard safety-belt used to install an integral belted Enhanced Child Restraint System shall not become disengaged from any guide or locking device utilized for the test conducted.;

6.2.1.4.

To prevent submarining, either by impact or through restlessness, a crotch strap shall be required on all integral forward-facing restraints incorporating an integral harness belt system. Enhanced Child Restraint Systems which incorporate a shield instead of a harness shall ensure that the shield extends across the full width of the child's body and sits low on the pelvis.

6.2.1.5.

All restraint devices utilizing a lap strap shall positively guide the lap strap to ensure that the loads 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 non-integral Enhanced Child restraint Systems, the lap portion of the adult safety-belt shall be positively guided on both sides to ensure that the loads 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°.

Image 23

The shoulder portion of the adult safety belt shall be positively guided to ensure that the child torso and neck do not escape.

6.2.1.6.

During the dynamic tests, the standard safety-belt used to install a non-integral Enhanced Child Restraint System, shall not become disengaged from any guide or locking device utilized for the test conducted; however, for the shoulder portion of the standard safety-belt this shall be judged up to the moment that the maximum horizontal head excursion of the dummy is reached.

6.2.1.7.

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. Y-shaped belts are not permitted on forward facing Enhanced Child Restraint Systems and may only be used in dedicated rearward facing and or lateral facing Enhanced Child Restraint Systems (carrycots). The distance between the shoulder-straps in the vicinity of the neck should be at least the width of the neck of the appropriate dummy.

6.2.1.8.

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 size range 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 size range covered by the approval.

An impact shield shall be adjustable so that it comes in contact with the pelvis and abdomen of the smallest and largest dummy within the size range covered by the approval, leaving no gap between the impact shield and the dummy.

6.2.1.9.

During the dynamic test, as prescribed in paragraph 7.1.3., the lap belt shall not pass fully beyond the pelvic structure of the dummy during the period prior to maximum horizontal head excursion. An assessment shall be carried out using high speed video imaging.

6.2.1.10.

At least the worst case of the dynamic test for the Enhanced Child Restraint System shall be performed after conditioning according to paragraph 7.2.6.

6.2.2.

The Enhanced Child Restraint System manufacturer shall declare in writing that the toxicity of materials used in the manufacture of restraint systems and accessible to the restrained child is in conformity with the test requirements of EN 71-3:2019, for a Category III material as defined in paragraph 4.2. Table 2 and following the test method of paragraph 7.2., specifically paragraph 7.2.2., Table 3, Category III sampling method. Tests confirming the validity of the declaration may be carried out at the discretion of the Technical Service. This paragraph does not apply to non-integral ECRS with a stature range of 100 cm or above.

6.3.1.2.

The flammability of Enhanced Child Restraint Systems submitted for approval shall be assessed by one of the following methods:

Method 1 is applicable only to non-built-in Enhanced Child Restraint Systems and Method 2 is applicable only to vehicle specific built-in Enhanced Child Restraint Systems.

Method 1

The Enhanced Child Restraint System manufacturer shall declare in writing that the flammability of materials used to manufacture the Enhanced Child Restraint System is in conformity with the method of section 5.4 of EN 71-2:2011+A1:2014 with a maximum rate of spread of flame of 30 mm/s. Tests confirming the validity of the declaration may be carried out at the discretion of the Technical Service. Where fabrics are assembled together, these shall be tested as a composite.

“Composite material" means a material composed of several layers of similar or different materials intimately held together at their surfaces by cementing, bonding, cladding, welding, etc. In such a case, the material shall be tested as a composite. When different materials are connected together intermittently, such materials shall not be considered as composite materials and therefore tested separately.

Tests confirming the validity of the declaration may be carried out at the discretion of the Technical Service.

Method 2

The applicant shall declare in writing that when testing materials in accordance with Annex 22 of this regulation, the materials used shall not burn, nor transmit a flame front across its surface, at a rate of more than 100 mm per minute.

Covering the test bench seat cushion and the test bench seat back cushion

3.1.7.1.   

The test bench seat cushion is produced out of a square foam block (800 × 575 × 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 (1 250 × 1 200 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 1 200 mm.

3.1.7.4.   

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 test bench seat cushion is placed upside down on the cover material with the aluminium bottom-plate on top.

3.1.7.6.

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 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 test bench seat-back cushion is covered in exactly the same way as the test bench seat cushion, only the lines on the cover material (1 250 × 850 mm) are drawn 333 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 test bench seat cushion and the front plane of the test bench seat-back cushion.

3.2.

2.   Panel padding specification

2.1.   General

The impact surface of the door panel shall be entirely covered with a padding material of 55 mm in thickness (see Figure 1 above). The material shall comply with the performance criteria specified in paragraph 2.3. (Figure 4 below) of this appendix when tested in accordance with paragraph 2.2. of this appendix.

A material combination meeting these requirements is described in paragraph 2.4. of this appendix.

2.2.   Test procedure for the assessment of panel padding material

The test set up consists of a simple drop test using a spherical head form. The spherical head form has a diameter of 150 mm and a mass of 6 kg (± 0,1 kg). The impact speed is 4 m/s (± 0,1 m/s). The instrumentation should allow the assessment of the time of first contact between the impactor and the sample as well as the head form acceleration at least in direction of impact (Z-direction).

The material sample should have the dimensions of 400 × 400 mm. The sample should be impacted in its centre.

2.3.   Performance criteria for the padding material

The time of first contact between sample material and head form (t0) is 0 ms.

The impactor acceleration shall not exceed 58 g.

ANNEX 8

Description of dummies

1.   General

1.1.

The dummies prescribed in this Regulation are described in this annex, in technical drawings (1) and in the user manuals. The abdominal pressure sensors prescribed in this Regulation are described in this annex, in technical drawings and in the user manuals.

1.2.

Alternative dummies and abdominal instrumentation may be used provided that:

1.2.1.

Their equivalence can be demonstrated to the satisfaction of the Type Approval Authority, and

1.2.2.

Their use is recorded in the test report, and in the communication form described in Annex 1 to this Regulation.

2.   Description of the dummies

2.1.

The dimensions and masses of the Q0, Q1, Q1,5, Q3, Q6 and Q10 dummies described below are based on the anthropometry of 50th percentile children aged 0, 1, 1,5, 3, 6 and 10,5 years respectively.

2.2.

The dummies consist of a metal and plastic skeleton covered with plastic skinned foam parts to complete body components.

3.   Construction

3.1.

Head

The head is largely made from synthetics. The head cavity is large enough to allow use of several instruments, including linear accelerometers and angular velocity sensors.

3.2.

Neck

The neck is flexible and allows shear and bending in all directions. The segmented design allows a realistic rotational behaviour. The neck is equipped with low stretch neck-cord in order to prevent excessive elongation. The neck-cord is also designed to act as a safety cord in case of rubber failure. A six channel load cell can be mounted at the neck-head and neck-torso interface. The Q0, Q1 and Q1,5 cannot accommodate the load cell between neck and torso.

3.3.

Thorax

The thorax of the child is represented by a single rib-cage. The deformation can be measured with a string potentiometer in Q1 and Q1,5 and an IR-TRACC sensors in Q3, Q6 and Q10. The shoulders are connected with a flexible joint to the thorax, allowing deformation forwards.

3.4.

Accelerometers can be mounted on the spine to measure linear accelerations. The Q0 thorax has a simplified layout with an integral foam part for the complete torso.

3.5.

Abdomen

The
