3.1.7.

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.

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 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.

Test of rearward-facing devices

3.2.1.

A special frame shall be fitted on the trolley in order to support the Enhanced Child Restraint System as shown in Figure 1.

3.2.2.

A steel tube shall be attached firmly to the trolley in such a way that a load of 5 000 ± 50 N applied horizontally to the centre of the tube does not cause a movement greater than 2 mm.

3.2.3.

Dimensions in mm

3.3.

Trolley floor pan

3.3.1.

The floor pan of the trolley shall be constructed of a flat sheet of metal of uniform thickness and material, see Figure 2 of Appendix 3 to this annex.

3.3.1.1.

The floor pan shall be rigidly mounted on the trolley. The height of the floor pan relative to the Cr axis projection point, dimension (1) in Appendix 2 to this annex, Figure 2, shall be adjusted to meet the requirements of paragraph 7.1.3.6.3. of this Regulation.

3.3.1.2.

The floor pan shall be designed so that the surface hardness should not be below 120 HB, according to EN ISO 6506-1:1999.

3.3.1.3.

The floor pan shall withstand an applied vertical concentrated load of 5 kN without causing a vertical movement greater than 2 mm referring to Cr axis and without any permanent deformation occurring.

3.3.1.4.

The floor pan shall have a surface roughness not exceeding Ra 6,3 according to ISO 4287:1997.

3.3.1.5.

The floor pan shall be designed so that no permanent deformation is occurring after a dynamic test of an Enhanced Child Restraint System, according to this Regulation.

4.

Stopping device

4.1.

The device consists of two identical absorbers mounted in parallel.

4.2.

If necessary, an additional absorber shall be used for each 200 kg increase in nominal mass. Each absorber shall comprise:

4.2.1.

An outer casing formed from a steel tube;

4.2.2.

A polyurethane energy-absorber tube;

4.2.3.

A polished-steel olive-shaped knob penetrating into the absorber; and

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.

In which:

1.2.1.

The term "a" is the resultant acceleration is measured in units of gravity, g (1 g = 9,81 m/s2);

1.2.2.

If the beginning of the head contact can be determined satisfactorily, t1 and t2 are the two time instants, expressed in seconds, defining an interval between the beginning of the head contact and the end of the recording for which the value of HPC is maximum;

1.2.3.

If the beginning of the head contact cannot be determined, t1 and t2 are the two time instants, expressed in seconds, defining a time interval between the beginning and the end of the recording for which the value of HPC is maximum;

1.2.4.

Values of HPC for which the time interval (t1 - t2) is greater than 15 ms are ignored for the purposes of calculating the maximum value.

1.3.

The value of the resultant head acceleration during forward impact which is exceeded for 3 ms cumulatively is calculated from the resultant head acceleration.

For each ECRS type (e.g. integral and non-integral);

| (c) | For any removable insert (e.g. for use as described by manufacturer’s instructions); |
| --- | --- |

(c)

For any removable insert (e.g. for use as described by manufacturer’s instructions);

| (d) | For each occupant restraint method (e.g. harness and shield). |
| --- | --- |

(d)

For each occupant restraint method (e.g. harness and shield).

The internal geometry assessment should be conducted with the ECRS placed on a flat surface or connected to a base in the case of ECRS modules.

For integral or non-integral ECRS the device shown in Annex 18, Figure 2 shall be used.

For ECRS with an impact shield the device shown in Annex 18, Figure 3 shall be used.

The mass of the devices described in Figure 2 and Figure 3 shall be 10 kg +/- 1 kg.

1.

The ECRS should be adjusted to fit the smallest occupant (i.e. headrest height, harness height adjustment, appropriate insert, internal padding, impact shield position), while still fitting within the required ISO volumetric envelope as defined in paragraph 6.3.2.2.

The measurement device shall then be placed in the ECRS. The device shall be aligned centrally to the ECRS.

All measurements shall be taken with the device base in contact with the seat pan of the ECRS and the device backrest in contact with the backrest of the ECRS. All lateral dimensions shall be measured under a contact force of 50 N with the devices described in Figure 2 and Figure 3 of this annex.

The measurements shall be taken in the following order:

1.1.

Minimum Shoulder Height (E1)

1.1.1.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned with the lowest harness slot position. For this alignment, the top of the shoulder cylinder shall be aligned perpendicular to the harness webbing outlet in the Enhanced Child Restraint System backrest.

A tolerance may be subtracted from this measurement to allow the shoulders of the occupant to be lower than the harness shoulder slots.

Either:

| (a) | If the Enhanced Child Restraint System instruction manual provided by the manufacturer quantifies the distance the child’s shoulder may be below the harness slots, then this distance shall be subtracted from the minimum shoulder height measurement; |
| --- | --- |

(a)

If the Enhanced Child Restraint System instruction manual provided by the manufacturer quantifies the distance the child’s shoulder may be below the harness slots, then this distance shall be subtracted from the minimum shoulder height measurement;

| (b) | If no distance is specified a 2 cm tolerance may be subtracted from the minimum shoulder height measurement. |
| --- | --- |

(b)

If no distance is specified a 2 cm tolerance may be subtracted from the minimum shoulder height measurement.

1.1.2.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned without interference with the lowest part of the headrest. A 2 cm tolerance may be subtracted from the minimum shoulder height measurement.

1.1.3.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned without interference with the lowest part of the headrest. A 2 cm tolerance may be subtracted from the minimum shoulder height measurement.

1.2.

This requirement only applies to Enhanced Child Restraint System with impact shields.

Whilst maintaining the minimum shoulder height position (E1), the minimum leg measurement shall be measured when the device is adjusted so that the simulated thighs contact the bottom of the impact shield.

1.3.

This requirement only applies to Enhanced Child Restraint System with impact shields

This measurement shall be taken whilst maintaining the minimum leg thickness measurement position (G1) and minimum shoulder height position (E1).

The bottom of the simulated abdomen of the device shall be aligned with the top of the simulated thighs.

The abdomen depth shall be measured when the simulated abdomen contacts the shield.

2.

Integral Enhanced Child Restraint System shall be adjusted to fit the largest occupant (i.e. headrest height, harness height adjustment, impact shield position), while still fitting within the required ISO volumetric envelope as defined in paragraph 6.3.2.2.1.

Non-integral Enhanced Child Restraint System shall be adjusted to accommodate children of 135 cm stature or to the largest size of its declared stature range if the upper limit is below 135 cm (i.e. headrest), while still fitting within the required ISO volumetric envelope as defined in paragraph 6.3.2.2.2.

The measurement device shall then be placed in the Enhanced Child Restraint System. The device shall be aligned centrally to the ECRS.

All measurements shall be taken with the device base in contact with the seat pan of the ECRS and the device backrest in contact with the backrest of the ECRS. All lateral dimensions shall be measured under a contact force of 50 N with the devices described in Figure 2 and Figure 3 of this annex

The measurements shall then be taken in the following order:

2.1.

This measurement shall be taken to the highest part of the Enhanced Child Restraint System that is the effective headrest (head pad or backrest).

A tolerance is added to this measurement to allow part of the head to protrude from the Enhanced Child Restraint System:

| (a) | +5 per cent for stature ranges below 87 cm; |
| --- | --- |

(a)

+5 per cent for stature ranges below 87 cm;

| (b) | +10 per cent for statures ranges above 87 cm. |
| --- | --- |

(b)

+10 per cent for statures ranges above 87 cm.

2.2.

The hip breadth measurement shall be taken while maintaining the sitting height measurement (B).

The hip breadth measurement shall be taken while asserting a 50 N contact force on the Enhanced Child Restraint System.

If 50 N force cannot be achieved, because the Enhanced Child Restraint System restricts the space at the simulated thighs then the measurement should be taken at the point the simulated thighs contact the Enhanced Child Restraint System. There shall be no lateral deformation of the Enhanced Child Restraint System caused by the measuring device.

2.3.

The maximum shoulder height measurement shall be taken while maintaining the sitting height (B) and hip breadth (D) measurements.

2.3.1.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned with the highest harness slot position still fitting within the required ISO volumetric envelope. For this alignment, the top of the shoulder cylinder shall be aligned perpendicular to the harness webbing outlet in the Enhanced Child Restraint System backrest.

A tolerance may be added to this measurement to allow the shoulders of the occupant to be higher than the harness shoulder slots. However if there is a physical restriction due to the design of the Enhanced Child Restraint System (e.g. the headrest) that would prevent a child with taller shoulders fitting the tolerance should not be added.

If there is no possible interference then the following tolerances may be added:

| (a) | If the Enhanced Child Restraint System instruction manual provided by the manufacturer quantifies the distance the child’s shoulder may be above the harness slots, then this distance shall be added to the maximum shoulder height measurement; |
| --- | --- |

(a)

If the Enhanced Child Restraint System instruction manual provided by the manufacturer quantifies the distance the child’s shoulder may be above the harness slots, then this distance shall be added to the maximum shoulder height measurement;

| (b) | If no distance is specified a 2 cm tolerance may be added to the maximum shoulder height measurement. |
| --- | --- |

(b)

If no distance is specified a 2 cm tolerance may be added to the maximum shoulder height measurement.

2.3.2.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned without interference with the lowest point of the headrest, this includes any belt routing guide.

No tolerance shall be added to this measurement.

2.3.3.

This measurement shall be taken when the top of the shoulder height cylinders of the device are aligned without interference with the lowest point of the headrest, this includes any belt routing guide.

No tolerance shall be added to this measurement.

2.4.

This requirement only applies to Enhanced Child Restraint System with impact shields.

This measurement shall be taken whilst maintaining the sitting height (B), hip breadth (D) and maximum shoulder height (E2) measurements.

The maximum upper leg thickness measurement shall be measured when the device is adjusted so that the simulated thighs contact the bottom of the impact shield.

2.5.

This requirement only applies to Enhanced Child Restraint System with impact shields.

This measurement shall be taken while maintaining the maximum upper leg thickness (G2), maximum shoulder height (E2), hip breadth (D) and sitting height (B) measurement positions.

The bottom of the simulated abdomen of the device shall be aligned with the top of the simulated thighs.

The abdomen depth shall be measured when the simulated abdomen contacts the shield.

2.6.

The shoulder breadth measurement shall be taken while maintaining the sitting height (B) and hip breadth (D) measurements.

The width of the ECRS at the maximum shoulder height measurement position shall be measured while asserting a 50 N contact force on the Enhanced Child Restraint System.

If there is no side wing structure to the Enhanced Child Restraint System at the maximum shoulder height (E2), the shoulder breadth measurement shall be taken at a height, which is the closest proximity to the maximum shoulder height, with side wing structure.

If the width of the Enhanced Child Restraint System between the minimum and maximum shoulder height measurements is not a consistent width, i.e. significantly narrower at any point between the E1 and E2 measurements, then an intermediate shoulder breadth measurements shall be taken.

3.

The measurements taken in Sections 1 and 2 shall then be compared to the values shown in Annex 18, Table 1.

Interpolation between the values shown in the table is allowed at one-centimetre intervals.

For each measurement, the corresponding stature at the nearest whole lower centimetre shall be calculated.

Maximum stature

For the measurements B, C, D, E2, F2 and G2, the measured value must be greater than or equal to the value shown in the table to meet the stature requirement.

For example to declare a stature of 105 cm the measured sitting height after applying tolerances must be greater or equal to 61,8 cm.

The maximum stature is the smallest stature calculated from the measurements B, C, D, E2, F2 and G2.

Minimum stature

For the measurements E1, F1 and G1, the measured value must be less than or equal to the value shown in the table to meet the stature requirement.

For example to declare a stature of 100 cm, the measured shoulder height after applying tolerances must be less than or equal to 32,4 cm.

The minimum stature is the largest stature calculated from the measurements E1, F1 and G1.
