SPECIFICATIONS

General specifications

Each sample submitted in conformity with paragraphs 3.2.2.2, 3.2.2.3 and 3.2.2.4 above shall
meet the specifications set forth in paragraph 6 of this Regulation.

The belt or the restraint system shall be so designed and constructed that, when correctly
installed and properly used by an occupant, its satisfactory operation is assured and it reduces the
risk of bodily injury in the event of an accident.

6.1.3.

The straps of the belt shall not be liable to assume a dangerous configuration.

6.1.4.

The use of materials with properties of polyamide 6 as regards water retention is prohibited in all
mechanical parts for which such a phenomenon is likely to have an adverse effect on their
operation.

6.2.

Rigid parts

6.2.1.

General

6.2.1.1.

The rigid parts of the safety-belt, such as buckles, adjusting devices, attachments and the like,
shall not have sharp edges liable to cause wear or breakage of the straps by chafing.

6.2.1.2.

All parts of the belt assembly liable to be affected by corrosion shall be suitably protected against
it. After undergoing the corrosion test prescribed in paragraph 7.2, neither signs of deterioration
likely to impair the proper functioning of the device nor any significant corrosion shall be visible
to the unaided eye of a qualified observer.

6.2.1.3.

Rigid parts intended to absorb energy or to be subjected to or to transmit a load shall not be
fragile.

6.2.1.4.

The rigid items and parts made of plastics of a safety-belt must be so located and installed that
they are not liable, during every day use of a power-driven vehicle, to become trapped under a
moveable seat or in a door of that vehicle. If any of these items and parts do not comply with the
above conditions, they shall be subjected to the cold impact test specified in paragraph 7.5.4
below. After the test, if any visible cracks are present in any plastic cover or retainer of rigid item,
the complete plastic part shall then be removed and the remaining assembly shall then be
assessed against its continued security. If the remaining assembly is still secure, or no visible
cracks are present, it will then be further assessed against the test requirements specified in
paragraphs 6.2.2, 6.2.3 and 6.4.

6.2.2

pulley, the retracting force shall be measured in the free length between the dummy and the guide
or pulley.

If the assembly incorporates a device that upon manual or automatic operation prevents the strap
from being completely retracted, such a device shall not be operated when these requirements are
assessed.

If the assembly incorporates a tension-reducing device, the retracting force of the strap described
in the above shall be measured with the device in operation mode and non-operation mode when
these requirements are assessed before and after durability tests according to paragraph 6.2.5.3.5.

6.2.5.3.5.

The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the method
described in paragraph 7.6.1 until 40 000 cycles have been completed. The retractor shall then be
subjected to the corrosion test given in paragraph 7.2 and after that to the dust test prescribed in
paragraph 7.6.3. It shall then satisfactorily complete a further 5 000 cycles (making 45 000

met the requirements of paragraph 6.2.2.4 above. In the case of safety-belts with retractors, the
retractor shall have been subjected to the dust resistance test laid down in paragraph 7.6.3; in
addition, in the case of safety-belts or restraint systems equipped with a pre-loading device
comprising pyrotechnic means, the device shall have been subjected to the conditioning specified
in paragraph 7.9.2.

6.4.1.2.1.

The belts shall have undergone the corrosion test described in paragraph 7.2, after which the
buckles shall be subjected to 500 additional opening and closing cycles under normal conditions
of use.

6.4.1.2.2.

Safety-belts with retractors shall have been subjected either to the tests described in paragraph
6.2.5.2 or to those described in paragraph 6.2.5.3. If, however, a retractor has already been
subjected to the corrosion test in accordance with the provisions of paragraph 6.4.1.2.1, above,
this test need not be repeated.

6.4.1.2.3.

In the case of a belt intended for use with a belt adjustment device for height, as defined in
paragraph 2.9.6 above, the test shall be carried out with the device adjusted in the most
unfavourable position(s) chosen by the technical service responsible for testing. However, if the
belt adjustment device for height is constituted by the belt anchorage, as approved in accordance

The dynamic test shall then be conducted with the tension-reducing device in operation mode.

6.4.1.3.

During this test, the following requirements shall be met:

6.4.1.3.1. No part of the belt assembly or a restraint system affecting the restraint of the occupant shall

break and no buckles or locking system or displacement system shall release or unlock; and

6.4.1.3.2.

the forward displacement of the manikin shall be between 80 and 200 mm at pelvic level in the
case of lap belts. In the case of other types of belts, the forward displacement shall be between 80
and 200 mm at pelvic level and between 100 and 300 mm at chest level. In the case of a harness
belt, the minimum displacements specified above may be reduced by half. These displacements
are the displacements in relation to the measurement points shown in Annex 7, figure 6 to this
Regulation.

6.4.1.4.

In the case of a restraint system:

6.4.1.4.1.

The movement of the chest reference point may exceed that specified in paragraph 6.4.1.3.2
above if it can be shown either by calculation or a further test that no part of the torso or the
head of the manikin used in the dynamic test would have come into contact with any forward
rigid part of the vehicle other than the chest with the steering assembly, if the latter meets the
requirements of Regulation No 12 and provided contact does not occur at a speed higher than 24
km/h. For this assessment the seat shall be considered to be in the position specified in paragraph
7.7.1.5 below.

6.4.1.4.2.

In vehicles where such devices are used, the displacement and locking systems enabling the
occupants of all seats to leave the vehicle shall still be operable by hand after the dynamic test.

The adjusting device shall be placed on the horizontal strap so that the strap remains under
tension (see Annex 11, Figure 1 to this Regulation).

7.4.1.6.4.2 Procedure 2: for cases where the strap changes direction in passing through a rigid part.

During this test, the angles of the straps shall be maintained as shown in Annex 11, Figure 2, to
this Regulation.

The steady load of 0,5 daN shall be maintained during the test.

For cases where the strap changes direction more than once in passing through a rigid part, the
load of 0,5 daN may be increased so as to achieve the prescribed strap movement of 300 mm
through that rigid part.

7.4.1.6.4.3. Procedure 3: for cases where the strap is fixed to a rigid part by sewing or similar means.

The total back and forth motion shall be 300 ± 20 mm but the 5 daN load shall only be applied
during a shift of 100 ± 20 mm for each half period (see Annex 11, figure 3, to this Regulation).

7.4.2.

Test of breaking strength of strap (static test)

7.4.2.1.

The test shall be carried out each time on two new samples of strap, of sufficient length,
conditioned in conformity with the provisions of paragraph 7.4.1.

7.4.2.2.

Each strap shall be gripped between the clamps of a tensile-testing machine. The clamps shall be
so designed as to avoid breakage of the strap at or near them. The speed of traverse shall be about
100 mm/min. The free length of the specimen between the clamps of the machine at the start of
the test shall be 200 mm ± 40 mm.

7.4.2.3.

When the load reaches 980 daN, the width of the strap shall be measured without stopping the
machine.

7.4.2.4.

The tension shall be increased until the strap breaks, and the breaking load shall be noted.

7.4.2.5.

If the strap slips or breaks at or within 10 mm of either of the clamps the test shall be invalid and
a new test shall be carried out on another specimen.

7.5.

Test of belt assembly components incorporating rigid parts

7.5.1.

The buckle and the adjusting device shall be connected to the tensile-testing apparatus by the
parts of the belt assembly to which they are normally attached, and the load shall then build up to
980 daN.

In the case of harness belts, the buckle shall be connected to the testing apparatus by the straps
which are attached to the buckle and the tongue or two tongues located in an approximately
symmetrical way to the geometric centre of the buckle. If the buckle, or the adjusting device, is
part of the attachment or of the common part of a three-point belt, the buckle or adjusting device
shall be tested with the attachment, in conformity with paragraph 7.5.2 below, except in the case
of retractors having a pulley or strap guide at the upper belt anchorage, when the load will be 980
daN and the length of strap remaining wound on the reel shall be the length resulting from
locking as close as possible to 450 mm from the end of the strap.

7.5.2.

The attachments and any belt adjustment devices for height shall be tested in the manner
indicated in paragraph 7.5.1, but the load shall be 1 470 daN and shall, subject to the provisions
of the second sentence of paragraph 7.7.1 below, be applied in the least favourable conditions
likely to occur in a vehicle in which the belt is correctly installed. In the case of retractors the test
is performed with the strap completely unwound from the reel.

immediately after being removed from the refrigerated cabinet.

Two samples of complete belt assembly shall be placed in a refrigerated cabinet at - 10 oC ± 1 oC
for two hours. The rigid items and parts made of plastics under test shall then be laid in turn
upon a flat rigid steel surface (which has been kept with the samples in the refrigerated cabinet)
placed on the horizontal surface of a compact rigid block with a mass of at least 100 kg and
within 30 seconds of being removed from the refrigerated cabinet, an 18 kg steel mass shall be
allowed to fall under gravity through 300 mm on to the test sample. The impact face of the 18 kg
mass shall take the form of a convex surface with a hardness of at least 45 HRC having a
transverse radius of 10 mm and a longitudinal radius of 150 mm placed along the centre line of
the mass. One test sample shall be tested with the axis of the curved bar in line with the strap and
the other sample shall be tested at 90o to the strap.

Buckles having parts common to two safety-belts shall be loaded in such a way as to simulate the
conditions of use in the vehicle with seats in the mid position of their adjustment. A load of
1 470 daN shall be applied sumultaneously to each strap. The direction of the application of load
shall be established according to paragraph 7.7.1 below. A suitable device for the test is shown in
Annex 10 to this Regulation.

When testing a manually adjusting device, the strap shall be drawn steadily through the adjusting
device, having regard for the normal conditions of use, at a rate of approximately 100 mm/s and
the maximum force measured to the nearest 0,1 daN after the first 25 mm of strap movement.
The test shall be carried out in both directions of strap travel through the device, the strap being
cycled 10 times prior to the measurement.

Additional tests for safety-belts with retractors

7.6.1.

Durability of retractor mechanism

7.6.1.1.

The strap shall be withdrawn and allowed to retract for the required number of cycles at a rate of
not more than 30 cycles per minute. In the case of emergency locking retractors, a snatch to lock
the retractor shall be introduced at each fifth cycle.

The snatches shall occur in equal numbers at each of five different extractions, namely, 90, 80,
75, 70 and 65 per cent of the total length of the strap remaining wound on the retractor.
However, where more than 900 mm is provided the above percentages shall be related to the
final 900 mm of strap which can be withdrawn from the retractor.

7.6.1.2.

A suitable apparatus for the tests specified in paragraph 7.6.1.1 above is shown in Annex 3 to
this Regulation.

7.6.2.

Locking of emergency locking retractors

7.6.2.1.

The retractor shall be tested once for locking when the strap has been unwound to full length less
300 ± 3 mm.

7.6.2.1.1.

In the case of a retractor actuated by strap movement, the extraction shall be in the direction in
which it normally occurs when the retractor is installed in a vehicle.

7.6.2.1.2. When retractors are being tested for sensitivity to vehicle deceleration they shall be tested at the
above extraction along two perpendicular axes, which are horizontal if the retractor is installed in
a vehicle as specified by the safety-belt manufacturer. When this position is not specified, the
testing authority shall consult the safety-belt manufacturer. One of these axes shall be in the
direction chosen by the technical service conducting the approval test to give the most adverse
conditions with respect to actuation of the locking mechanism.

7.6.2.2.

A suitable apparatus for the tests specified in paragraph 7.6.2.1 above is described in Annex 4 to
this Regulation. The design of any such test apparatus shall ensure that the required acceleration
is given before the webbing is withdrawn out of the retractor by more than 5 mm and that the
withdrawal takes place at an average rate of increase of acceleration of at least 25 g/s (4) and not
more than 150 g/s (4).

7.6.2.3.

To check conformity with the requirements of paragraphs 6.2.5.3.1.3 and 6.2.5.3.1.4, the
retractor shall be mounted on a horizontal table and the table tilted with a speed not exceeding 2o
per second until locking has occurred. The test shall be repeated with tilting in other directions to
ensure that the requirements are fulfilled.

7.6.3.

Dust resistance

7.6.3.1.

The retractor shall be positioned in a test chamber as described in Annex 5 to this Regulation. It
shall be mounted in an orientation similar to that in which it is mounted in the vehicle. The test
chamber shall contain dust as specified in paragraph 7.6.3.2 below. A length of 500 mm of the
strap shall be extracted from the retractor and kept extracted, except that it shall be subjected to
10 complete cycles of retraction and withdrawal within one or two minutes after each agitation
of the dust. For a period of five hours, the dust shall be agitated every 20 minutes for five seconds
by compressed air free of oil and moisture at a gauge pressure of 5,5 · 105 + 0,5 · 105 Pa entering
through an orifice, 1,5 ± 0,1 mm in diameter.

7.6.3.2.

The dust used in the test described in paragraph 7.6.3.1 above shall consist of about 1 kg of dry
quartz. The particle size distribution is as follows:

(a)

passing 150 μm aperture, 104 μm wire diameter: 99 to 100 per cent;

(b)

passing 105 μm aperture, 64 μm wire diameter: 76 to 86 per cent

(c)

passing 75 μm aperture, 52 μm wire diameter: 60 to 70 per cent.

7.6.4.

Retracting forces

7.6.4.1.

The retracting force shall be measured with the safety-belt assembly fitted to a dummy as for the
dynamic test prescribed in paragraph 7.7. The strap tension shall be measured at the point of
contact with (but just clear of) the dummy while the strap is being retracted at the approximate
rate of 0,6 m/min. In the case of a safety-belt with tension-reducing device, the retracting force
and strap tension shall be measured with the tension-reducing device in both operation mode
and non-operation mode.

7.6.4.2.

Before the dynamic test described in paragraph 7.7 the seated dummy, which is clothed with a
cotton shirt, shall be tilted frontward until 350 mm of the strap is withdrawn from retractor, and
then released to the initial position.

7.7.

Dynamic test of belt assembly or of the restraint system

7.7.1.

The belt assembly shall be mounted on a trolley equipped with the seat and the anchorage
defined in Annex 6 to this Regulation. However, if the belt assembly is intended for a specific
vehicle or for specific types of vehicle, the distances between the manikin and the anchorages
shall be determined by the service conducting the tests, either in conformity with the instructions
for fitting supplied with the belt or in conformity with the data supplied by the manufacturer of
the vehicle. If the belt is equipped with a belt adjustment device for height such as defined in
paragraph 2.9.6 above, the position of the device and the means of securing it shall be the same
as those of the vehicle design.

In that case, when the dynamic test has been carried out for a type of vehicle it need not be
repeated for other types of vehicle where each anchorage point is less than 50 mm distant from
the corresponding anchorage point of the tested belt. Alternatively, manufacturers may determine
hypothetical anchorage positions for testing in order to enclose the maximum number of real
anchorage points.

7.7.1.1.

In the case of a safety-belt or restraint system forming part of an assembly for which type
approval is requested as a restraint system, the safety-belt shall be mounted on the part of the
vehicle structure to which the restraint system is normally fitted and this part shall be rigidly
attached to the test trolley in the way prescribed in paragraphs 7.7.1.2 to 7.7.1.6.

In the case of a safety-belt or restraint system with pre-loading devices relying on component
parts other than those incorporated in the belt assembly itself, the belt assembly shall be
mounted in conjunction with the necessary additional vehicle parts on the test trolley in the
manner prescribed in paragraphs 7.7.1.2 to 7.7.1.6.

The method used to secure the vehicle during the test shall not be such as to strengthen the
anchorages of the seats or safety-belts or to lessen the normal deformation of the structure. No
forward part of the vehicle shall be present which by limiting the forward movement of the
manikin excepting the foot, would reduce the load imposed on the restraint system during the
test. The parts of the structure eliminated can be replaced by parts of equivalent strength
provided they do not hinder the forward movement of the manikin.

A securing device shall be regarded as satisfactory if it produces no effect on an area extending
over the whole width of the structure and if the vehicle or the structure is blocked or fixed in
front at a distance of not less than 500 mm from the anchorage of the restraint system. At the
rear the structure shall be secured at a sufficient distance rearwards of the anchorages to ensure
that the requirements of paragraph 7.7.1.2 above are fulfilled.

The seats shall be fitted and shall be placed in the position for driving use chosen by the technical
service conducting approval tests to give the most adverse conditions with respect to strength,
compatible with installing the manikin in the vehicle. The positions of the seats shall be stated in

All the seats of any group of seats shall be tested simultaneously.

7.7.1.7.

The dynamic tests of the harness belt system shall be carried out without the crotch strap
(assembly), if there is any.

7.7.2.

The belt assembly shall be attached to the manikin in Annex 7 to this Regulation as follows: a
board 25 mm thick shall be placed between the back of the manikin and the seat back. The belt
shall be firmly adjusted to the manikin. The board shall then be removed so that the entire length
of its back is in contact with the seat back. A check shall be made to ensure that the mode of
engagement of the two parts of the buckle entails no risk of reducing the reliability of locking.

7.7.3.

The free ends of the straps shall extend sufficiently far beyond the adjusting devices to allow for
slip.

The trolley shall then be so propelled that at the moment of impact its free running speed is 50
km/h ± 1 km/h and the manikin remains stable. The stopping distance of the trolley shall be 40
cm ± 5 cm. The trolley shall remain horizontal throughout deceleration. The deceleration of the
trolley shall be achieved by using the apparatus described in Annex 6 to this Regulation or any
other device giving equivalent results. This apparatus shall comply with the performance specified
in Annex 8 to this Regulation.

The trolley speed immediately before impact, the forward displacement of the manikin and the
speed of the chest at a 300 mm displacement of the chest shall be measured.

After impact, the belt assembly or restraint system and its rigid parts shall be inspected visually,
without opening the buckle, to determine whether there has been any failure or breakage. In the
case of restraint systems it shall also be ascertained, after the test, whether the parts of the vehicle
structure which are attached to the trolley have undergone any visible permanent deformation. If
there is any such deformation this shall be taken into account in any calculation made in
accordance with paragraph 6.4.1.4.1.

n

subjected to the force of

daN. (It is understood that n is the number of straps linked to the

buckle when it is in a locked position.) In the case where the buckle is connected to a rigid part,
the load shall be applied at the same angle as the one formed by the buckle and the rigid end
during the dynamic test. A load shall be applied at a speed of 400 ± 20 mm/min to the geometric
centre of the buckle-release button along a fixed axis running parallel to the initial direction of
motion of the button. During the application of the force needed to open the buckle, the buckle
shall be held by a rigid support. The load quoted above shall not exceed the limit indicated in
paragraph 6.2.2.5 above. The point of contact of the test equipment shall be spherical in form
with a radius of 2,5 mm ± 0,1 mm. It shall have a polished metal surface.

7.8.3.

The buckle-opening force shall be measured and any failure of the buckle noted.

7.8.4.

After the buckle-opening test, the components of the belt assembly or of the restraint device
which have undergone the tests prescribed in paragraph 7.7 above shall be inspected and the
extent of the damage sustained by the belt assembly or restraint device during the dynamic test
shall be recorded in the test report.

The pre-loading device may be separated from the safety-belt to be tested and kept for 24 hours at
a temperature of 60o ± 5 oC. The temperature shall then be raised to 100o ± 5 oC for two hours.
Subsequently it shall be kept for 24 hours at a temperature of - 30o ± 5 oC. After being removed
from conditioning, the device shall warm up to ambient temperature. If it has been separated it
shall be fitted again to the safety-belt.

REQUIREMENTS CONCERNING THE INSTALLATION IN THE VEHICLE

Vehicle equipment

With the exception of folding seats (as defined in Regulation No 14) and seating intended solely
for use when the vehicle is stationary, the seats of vehicles of categories M and N as defined in
Annex 7 to the Consolidated Resolution (R.E.3) (*) (except those vehicles of categories M2 and M3
which belong to Classes I or II, according to Regulation No 36, to Class A, according to
Regulation No 52 and to Classes I or II and A, according to Regulation No 107) must be
equipped with safety-belts or restraint systems which satisfy the requirements of this Regulation.

The types of safety-belts or restraint systems for each seating position where installation is
required shall be those specified in Annex 16 (with which neither non-locking retractors (para.
2.14.1) nor manually unlocking retractor (para. 2.14.2) can be used). For all seating positions
where lap belts type B are specified in Annex 16 lap belts type Br3 are permitted except in the
case that, in use, they retract to such an extent as to reduce comfort in a notable way after normal
buckling up.

However, for outboard seating positions, other than front, of vehicles of the category N1 shown
in Annex 16 and marked with the symbol Ø, the installation of a lap belt of type Br4m or Br4Nm
is allowed, where there exists a passage between a seat and the nearest side wall of the vehicle
intended to permit access of passengers to other parts of the vehicle. A space between a seat and
the side wall is considered as a passage, if the distance between that side wall, with all doors
closed, and a vertical longitudinal plane passing through the centre line of the seat concerned —
measured at the R-point position and perpendicularly to the median longitudinal plane of the
vehicle — is more than 500 mm.

Where no safety-belts are required any type of safety-belt or restraint system conforming to this
Regulation may be provided at the choice of the manufacturer. A-type belts of the types
permitted in Annex 16 may be provided as an alternative to lap belts for those seating positions
where lap belts are specified in Annex 16.

On three point belts fitted with retractors, one retractor must operate at least on the diagonal
strap.

Except for vehicles of category M1 an emergency locking retractor of type 4N (para. 2.14.5) may
be permitted instead of a retractor of type 4 (para. 2.14.4) where it has been shown to the
satisfaction of the services responsible for the tests that the fitting of a type 4 retractor would not
be practical.

For the front outboard and the front centre seating positions shown in Annex 16 and marked
with the symbol *, lap belts of the type specified on that annex shall be considered adequate
where the windscreen is located outside the reference zone defined in Annex 1 to Regula-
tion No 21.

As regards safety-belts, the windscreen is considered as part of the reference zone when it is
capable of entering into static contact with the test apparatus according to the method described
in Annex 1 of Regulation No 21.

DESCRIPTION OF CURVE OF TROLLEY'S DECELERATION AS A FUNCTION OF TIME

(Curve for testing stopping devices)

The deceleration curve of the trolley weighted with inert mass to produce a total mass of 455 kg ± 20 kg for safety-belt tests
and 910 ± 40 kg for restraining system tests where the nominal mass of the trolley and vehicle structure is 800 kg must
remain within the hatched area above. If necessary, the nominal mass of the trolley and attached vehicle structure can be
increased by increments of 200 kg, in which case, an additional inert mass of 28 kg per increment shall be added. In no case
shall the total mass of the trolley and vehicle structure and inert masses differ from the nominal value for calibration tests by
more than ± 40 kg. During calibration of the stopping device, the speed of the trolley shall be 50 km/h ± 1 km/h and the
stopping distance shall be 40 cm ± 2 cm. In both the above cases the calibration and measuring procedures shall correspond
to those defined in the International Standard ISO 6487:1980; the measuring equipment shall correspond to the
specification of a data channel with a channel frequency class (CFC) 60.

ANNEX 15

PROCEDURE FOR DETERMINING THE ‘H’ POINT AND THE ACTUAL TORSO ANGLE FOR SEATING
POSITIONS IN MOTOR VEHICLES

1.

PURPOSE

The procedure described in this annex is used to establish the ‘H’ point location and the actual torso angle for one
or several seating positions in a motor vehicle and to verify the relationship of measured data to design
specifications given by the vehicle manufacturer (1).

2.

DEFINITIONS

For the purposes of this annex:

2.1.

‘Reference data’ means one or several of the following characteristics of a seating position:

2.1.1.

the ‘H’ point and the ‘R’ point and their relationship,

2.1.2.

the actual torso angle and the design torso angle and their relationship.

2.2.

2.3.

‘Three-dimensional “H” point machine’ (3-D H machine) means the device used for the determination of ‘H’ points
and actual torso angles. This device is described in Appendix 1 to this annex;

‘“H” point’ means the pivot centre of the torso and the thigh of the 3-D H machine installed in the vehicle seat in
accordance with paragraph 4 below. The ‘H’ point is located in the centre of the centreline of the device which is
between the ‘H’ point sight buttons on either side of the 3-D H machine. The ‘H’ point corresponds theoretically to
the ‘R’ point (for tolerances see paragraph 3.2.2 below). Once determined in accordance with the procedure
described in paragraph 4, the ‘H’ point is considered fixed in relation to the seat-cushion structure and to move
with it when the seat is adjusted;

2.4.

‘“R” point’ or ‘seating reference point’ means a design point defined by the vehicle manufacturer for each seating
position and established with respect to the three-dimensional reference system;

2.5.

‘Torso-line’ means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position;

2.6.

2.7.

2.8.

‘Actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using
the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design
torso angle (for tolerances see paragraph 3.2.2. below):

‘Design torso angle’ means the angle measures between a vertical line through the ‘R’ point and the torso line in a
position which corresponds to the design position of the seat-back established by the vehicle manufacturer;

‘Centreplane of occupant’ (C/LO) means the median plane of the 3-D H machine positioned in each designated
seating position; it is represented by the co-ordinate of the ‘H’ point on the ‘Y’ axis. For individual seats, the
centreplane of the seat coincides with the centreplane of the occupant. For other seats, the centreplane of the
occupant is specified by the manufacturer;

2.9.

‘Three-dimensional reference system’ means a system as described in Appendix 2 to this annex;

2.10.

‘Fiducial marks’ are physical points (holes, surfaces, marks or indentations) on the vehicle body as defined by the
manufacturer;

2.11.

‘Vehicle measuring attitude’ means the position of the vehicle as defined by the co-ordinates of fiducial marks in
the three-dimensional reference system.

(1)

In any seating position other than front seats where the ‘H’ point cannot be determined using the ‘Three-dimensional “H” point machine’
or procedures, the ‘R’ point indicated by the manufacturer may be taken as a reference at the discretion of the competent authority.

3.

REQUIREMENTS

3.1.

Data presentation

For each seating position where reference data are required in order to demonstrate compliance with the
provisions of the present Regulation, all or an appropriate selection of the following data shall be presented in the
form indicated in Appendix 3 to this annex:

3.1.1.

the co-ordinates of the ‘R’ point relative to the three-dimensional reference system;

3.1.2.

the design torso angle;

3.1.3.

all indications necessary to adjust the seat (if it is adjustable) to the measuring position set out in paragraph 4.3
below.

3.2.

Relationship between measured data and design specifications

3.2.1.

3.2.2.

The co-ordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in
paragraph 4 below shall be compared, respectively, with the co-ordinates of the ‘R’ point and the value of the
design torso angle indicated by the vehicle manufacturer.

The relative positions of the ‘R’ point and the ‘H’ point and the relationship between the design torso angle and the
actual torso angle shall be considered satisfactory for the seating position in question if the ‘H’ point, as defined by
its co-ordinates, lies within a square of 50 mm side length with horizontal and vertical sides whose diagonals
intersect at the ‘R’ point, and if the actual torso angle is within 5o of the design torso angle.

3.2.3.

If these conditions are met, the ‘R’ point and the design torso angle, shall be used to demonstrate compliance with
the provisions of this Regulation.

3.2.4.

3.2.5.

4.

4.1.

If the ‘H’ point or the actual torso angle does not satisfy the requirements of paragraph 3.2.2 above, the ‘H’ point
and the actual torso angle shall be determined twice more (three times in all). If the results of two of these three
operations satisfy the requirements, the conditions of paragraph 3.2.3 above shall apply.

If the results of at least two of the three operations described in paragraph 3.2.4 above do not satisfy the
requirements of paragraph 3.2.2 above, or if the verification cannot take place because the vehicle manufacturer
has failed to supply information regarding the position of the ‘R’ point or regarding the design torso angle, the
centroid of the three measured points or the average of the three measured angles shall be used and be regarded as
applicable in all cases where the ‘R’ point or the design torso angle is referred to in this Regulation.

PROCEDURE FOR ‘H’ POINT AND ACTUAL TORSO ANGLE DETERMINATION

The vehicle shall be preconditioned at the manufacturer's discretion, at a temperature of 20 ± 10 oC to ensure that
the seat material reached room temperature. If the seat to be checked has never been sat upon, a 70 to 80 kg
person or device shall sit on the seat twice for one minute to flex the cushion and back. At the manufacturer's
request, all seat assemblies shall remain unloaded for a minimum period of 30 minutes prior to installation of the
3-D H machine.

4.2.

The vehicle shall be at the measuring attitude defined in paragraph 2.11 above.

4.3.

4.4.

The seat, if it is adjustable, shall be adjusted first to the rearmost normal driving or riding position, as indicated by
the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat
travel used for purposes other than normal driving or riding positions. Where other modes of seat adjustment
exist (vertical, angular, seat-back, etc.) these will then be adjusted to the position specified by the vehicle
manufacturer. For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving
position as specified by the manufacturer.

The area of the seating position contacted by the 3-D H machine shall be covered by a muslin cotton, of sufficient
size and appropriate texture, described as a plain cotton fabric having 18,9 threads per cm2 and weighing 0,228
kg/m2 or knitted or non-woven fabric having equivalent characteristics. If the test is run on a seat outside the
vehicle, the floor on which the seat is placed shall have the same essential characteristics (2) as the floor of the
vehicle in which the seat is intended to be used.

(2) Tilt angle, height difference with a seat mounting, surface.

4.6.

Place the seat and back assembly of the 3-D H machine so that the centreplane of the occupant (C/LO) coincides
with the centreplane of the 3-D H machine. At the manufacturer's request, the 3-D H machine may be moved
inboard with respect to the C/LO if the 3-D H machine is located so far outboard that the seat edge will not permit
levelling of the 3-D H machine.

Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and
lower leg assembly. A line through the ‘H’ point sight buttons shall be parallel to the ground and perpendicular to
the longitudinal centreplane of the seat.

4.7.

Adjust the feet and leg positions of the 3-D H machine as follows:

4.7.1.

Designated seating position: driver and outside front passenger

4.7.1.1. Both feet and leg assemblies shall be moved forward in such a way that the feet take up natural positions on the
floor, between the operating pedals if necessary. Where possible the left foot shall be located approximately the
same distance to the left of the centreplane of the 3-D H machine as the right foot is to the right. The spirit level
verifying the transverse orientation of the 3-D H machine is brought to the horizontal by readjustment of the seat
pan if necessary, or by adjusting the leg and foot assemblies towards the rear. The line passing through the ‘H’ point
sight buttons shall be maintained perpendicular to the longitudinal centreplane of the seat.

4.7.1.2.

If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move
the left foot until it is supported. The alignment of the sight buttons shall be maintained.

4.7.2.

Designated seating position: outboard rear

For rear seats or auxiliary seats, the legs are located as specified by the manufacturer. If the feet then rest on parts of
the floor which are at different levels, the foot which first comes into contact with the front seat shall serve as a
reference and the other foot shall be so arranged that the spirit level giving the transverse orientation of the seat of
the device indicates the horizontal.

4.7.3.

Other designated seating positions:

The general procedure indicated in paragraph 4.7.1 above shall be followed except that the feet shall be placed as
specified by the vehicle manufacturer.

4.8.

Apply lower leg and thigh weights and level the 3-D H machine.

4.9.

Tilt the back pan forward against the forward stop and draw the 3-D H machine away from the seat-back using the
T-bar. Reposition the 3-D H machine on the seat by one of the following methods:

4.9.1.

4.9.2.

4.10.

If the 3-D H machine tends to slide rearward, use the following procedure. Allow the 3-D H machine to slide
rearward until a forward horizontal restraining load on the T-bar is no longer required i.e. until the seat pan
contacts the seat-back. If necessary, reposition the lower leg.

If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine
rearwards by applying a horizontal rearward load to the T-bar until the seat pan contacts the seat-back (see figure
2 of Appendix 1 to this annex).

Apply a 100 ± 10 N load to the back and pan assembly of the 3-D H machine at the intersection of the hip angle
quadrant and the T-bar housing. The direction of load application shall be maintained along a line passing by the
above intersection to a point just above the thigh bar housing (see figure 2 of Appendix 1 to this annex). Then
carefully return the back pan to the seat-back. Care must be exercised throughout the remainder of the procedure
to prevent the 3-D H machine from sliding forward.

4.11.

Install the right and left buttock weights and then, alternately, the eight torso weights. Maintain the 3-D H machine
level.

4.12.

Tilt the back pan forward to release the tension on the seat-back. Rock the 3-D H machine from side to side
through a 10o arc (5o to each side of the vertical centreplane) for three complete cycles to release any accumulated
friction between the 3-D H machine and the seat.

During the rocking action, the T-bar of the 3-D H machine may tend to diverge from the specified horizontal and
vertical alignment. The T-bar must therefore be restrained by applying an appropriate lateral load during the
rocking motions. Care shall be exercised in holding the T-bar and rocking the 3-D H machine to ensure that no
inadvertent exterior loads are applied in a vertical or fore and aft direction.

30.11.2007

EN

Official Journal of the European Union

L 313/123

The feet of the 3-D H machine are not to be restrained or held during this step. If the feet change position, they
should be allowed to remain in that attitude for the moment.

Carefully return the back pan to the seat-back and check the two spirit levels for zero position. If any movement of
the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows:

Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is
obtained. During this lifting, the feet are to be free to rotate; and no forward or lateral loads are to be applied.
When each foot is placed back in the down position, the heel is to be in contact with the structure designed for
this.

Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of the back pan sufficient
to level the 3-D H machine's seat pan on the seat.

4.13.

Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion, proceed as follows:

(a)

return the back pan to the seat-back;

(b)

alternately apply and release a horizontal rearward load, not to exceed 25 N, to the back angle bar at a height
approximately at the centre of the torso weights until the hip angle quadrant indicates that a stable position
has been reached after load release. Care shall be exercised to ensure that no exterior downward or lateral
loads are applied to the 3-D H machine. If another level adjustment of the 3-D H machine is necessary, rotate
the back pan forward, re-level, and repeat the procedure from paragraph 4.12.

4.14.

Take all measurements:

4.14.1. The co-ordinates of the ‘H’ point are measured with respect to the three-dimensional reference system.

4.14.2. The actual torso angle is read at the back angle quadrant of the 3-D H machine with the probe in its fully rearward

position.

4.15.

4.16.

If a re-run of the installation of the 3-D H machine is desired the seat assembly should remain unloaded for a
minimum period of 30 minutes prior to the re-run. The 3-D H machine should not be left loaded on the seat
assembly longer than the time required to perform the test.

If the seats in the same row can be regarded as similar (bench seat, identical seats, etc.) only one ‘H’ point and one
‘actual torso angle’ shall be determined for each row of seats, the 3-D H machine described in Appendix 1 to this
annex being seated in a place regarded as representative for the row. This place shall be:

4.16.1.

in the case of the front row, the driver's seat;

4.16.2.

in the case of the rear row or rows, an outer seat.

Appendix 1

DESCRIPTION OF THE THREE DIMENSIONAL ‘H’ POINT MACHINE (*)

(3-D H machine)

1.

BACK AND SEAT PANS

The back and seat pans are constructed of reinforced plastic and metal; they simulate the human torso and thigh and
are mechanically hinged at the ‘H’ point. A quadrant is fastened to the probe hinged at the ‘H’ point to measure the
actual torso angle. An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a
baseline for the hip angle quadrant.

2.

BODY AND LEG ELEMENTS

Lower leg segments are connected to the seat pan assembly at the T-bar joining the knees, which is a lateral extension
of the adjustable thigh bar. Quadrants are incorporated in the lower leg segments to measure knee angles. Shoe and
foot assemblies are calibrated to measure the foot angle. Two spirit levels orient the device in space. Body element
weights are placed at the corresponding centres of gravity to provide seat penetration equivalent to a 76 kg male. All
joints of the 3-D H machine should be checked for free movement without encountering noticeable friction.

CHILD RESTRAINT SYSTEMS OF UNIVERSAL AND SEMI-UNIVERSAL CATEGORIES INSTALLED ON ISOFIX
POSITIONS

1.

GENERAL

1.1. The test procedure and the requirements in this appendix shall be used to determine the suitability of Isofix positions

for the installation of Isofix child restraint systems of universal and semi-universal categories.

1.2. The tests may be carried out in the vehicle or in a representative part of the vehicle.

2.

TEST PROCEDURE

For any Isofix position in the vehicle, as indicated by the car manufacturer, in table 2 of Appendix 3, it has to be
checked that it is possible to accommodate the corresponding child restraint fixture(s) (CRF):

2.1. When checking a CRF on a seat, this seat may be adjusted longitudinally to its rearmost position and in its lowest

position.

2.2. Adjust the seat-back angle to the manufacturer's design position and the head restraint in the lowest and rearmost
position. In the absence of any specification an angle of the seat-back corresponding to a torso angle of 25o from the
vertical, or the nearest fixed position of the seat-back, shall be used.

When checking a CRF on a rear seat, the vehicle seat located in front of this rear seat may be adjusted longitudinally
forward but not further than the mid position between its rearmost and fore most positions. The seat backrest angle
may also be adjusted, but not to a more upright angle than corresponding to a torso angle of 15o.

2.3. Place a cotton cloth on the seat-back and cushion.

2.4. Place the CRF on the Isofix position.

2.5. Push, towards Isofix anchorages system, on the center between the ISOFIX anchorages with a force of 100 N ± 10 N,

applied parallel to the lower surface, and remove the force.

2.6. Attach the CRF to the Isofix anchorages system.
