0.7 daN when measured in the free length between the dummy and the retractor in
accordance with Paragraph 7.6.4.
If the retractor is part of an upper torso restraint, the retracting force of the strap shall be not
less than 0.1 daN and not more than 0.7 daN when similarly measured, except for a belt
equipped with a tension-reducing device, in which case the minimum retracting force may
be reduced to 0.05 daN only when such a device is in operation mode. If the strap passes
through a guide or 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 The strap shall be withdrawn from the retractor and allowed to retract repeatedly by the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 in all).
If the assembly incorporates a tension-reducing device, the above tests shall be conducted
on condition that the tension-reducing device is in operation mode and in non-operation
mode.
After the above tests, the retractor shall operate correctly and still meet the requirements of
Paragraphs 6.2.5.3.1., 6.2.5.3.3., and 6.2.5.3.4. above.
6.2.5.4. Retractors must fulfil, after durability test according to Paragraph 6.2.5.3.5., and immediately
after the retracting force measurement according to Paragraph 6.2.5.3.4., all next two
specifications:
6.2.5.4.1. When retractors except automatically locking retractors are tested according to
Paragraph 7.6.4.2., the retractors must be able to avoid any slack between torso and belt,
and,
6.2.5.4.2. When the buckle is unlatched to release the tongue, the retractor alone must be able to
retract strap fully.
6.2.6. Pre-loading device
6.2.6.1. After being submitted to corrosion testing in accordance with Paragraph 7.2., the
pre-loading device (including the impact sensor connected to the device by the original
plugs but without any current passing through them) shall operate normally.
6.2.6.2. It shall be verified that inadvertent operation of the device does not involve any risk of bodily
injury for wearer.

6.4.1.2. The dynamic test shall be performed on two belt assemblies which have not previously been
under load, except in the case of belt assemblies forming part of restraint systems when the
dynamic test shall be performed on the restraint systems intended for one group of seats
which have not previously been under load. The buckles of the belt assemblies to be tested
shall have 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 with the provisions of Regulation No. 14, the technical service responsible for
testing may, at its discretion, apply the provisions of Paragraph 7.7.1. below.
6.4.1.2.4. In the case of a safety-belt with a pre-loading device the minimum displacement specified in
Paragraph 6.4.1.3.2. below may be reduced by half. For the purpose of this test, the
pre-loading device shall be in operation.
6.4.1.2.5. In the case of a safety-belt with tension-reducing device, it shall be subjected to a durability
test with such a device in operation mode according to Paragraph 6.2.5.3.5 before a
dynamic test. 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.
6.4.1.3.3. In the case of a safety-belt intended to be used in an outboard front seating position
protected by an airbag in front of it, the displacement of the chest reference point may
exceed that specified in Paragraph 6.4.1.3.2. above if its speed at this value does not
exceed 24 km/h.

sample shall be preserved so long as the approval remains valid.
7.2. Corrosion Test
7.2.1. A complete safety belt assembly shall be positioned in a test chamber as prescribed in
Annex 12 to this Regulation. In the case of an assembly incorporating a retractor, the strap
shall be unwound to full length less 300 ± 3 mm. Except for short interruptions that may be
necessary, for example, to check and replenish the salt solution, the exposure test shall
proceed continuously for a period of 50 hours.
7.2.2. On completion of the exposure test the assembly shall be gently washed, or dipped in clean
running water with a temperature not higher than 38° C to remove any salt deposit that may
have formed and then allowed to dry at room temperature for 24 hours before inspection in
accordance with Paragraph 6.2.1.2. above.
7.3. Micro-slip Test (See Annex 11, Figure 3 to this Regulation)
7.3.1. The samples to be submitted to the micro-slip test shall be kept for a minimum of 24 hours
in an atmosphere having a temperature of 20 ± 5° C and a relative humidity of
65 ± 5%. The test shall be carried out at a temperature between 15 and 30° C.
7.3.2. It shall be ensured that the free section of the adjusting device points either up or down on
the test bench, as in the vehicle.
7.3.3. A 5 daN load shall be attached to the lower end of the section of strap. The other end shall
be subjected to a back and forth motion, the total amplitude being 300 ± 20 mm (see figure).
7.3.4. If there is a free end serving as reserve strap, it must in no way be fastened or clipped to the
section under load.
7.3.5. It shall be ensured that on the test bench the strap, in the slack position, descends in a
concave curve from the adjusting device, as in the vehicle. The 5 daN load applied on the
test bench shall be guided vertically in such a way as to prevent the load swaying and the
belt twisting. The attachment shall be fixed to the 5 daN load as in the vehicle.
7.3.6. Before the actual start of the test, a series of 20 cycles shall be completed so that the
self-tightening system settles properly.
7.3.7. 1 000 cycles shall be completed at a frequency of 0.5 cycles per second, the total amplitude
being 300 ± 20 mm. The 5 daN load shall be applied only during the time corresponding to
a shift of 100 ± 20 mm for each half period.

7.4.1.5.2. The breaking load shall be determined within 10 minutes after removal of the strap from the
water.
7.4.1.6. Abrasion Conditioning
7.4.1.6.1. The abrasion conditioning will be performed on every device in which the strap is in contact
with a rigid part of the belt, with the exception of all adjusting devices where the micro-slip
test (7.3.) shows that the strap slips by less than half the prescribed value, in which case,
the Procedure 1 abrasion conditioning (7.4.1.6.4.1.) will not be necessary. The setting on
the conditioning device will approximately maintain the relative position of strap and contact
area.
7.4.1.6.2. The samples shall be kept for a minimum of 24 hours in an atmosphere having a
temperature of 20 ± 5° C and relative humidity of 65 ± 5%. The ambient temperature during
the abrasion procedure shall be between 15 and 30° C.
7.4.1.6.3. In the table below are listed the general conditions for each abrasion procedure.

The shift given in the fifth column of this table represents the amplitude of a back and forth
motion applied to the strap.
7.4.1.6.4. Particular conditioning procedures.
7.4.1.6.4.1. Procedure 1: for cases where the strap slides through an adjusting device.
A vertical steady load of 2.5 daN shall be maintained on one end of the strap - the other end
of the strap shall be attached to a device giving the strap a horizontal back and forth motion.
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.

7.5.4. Two samples of complete belt assembly shall be placed in a refrigerated cabinet at
- 10° C ± 1° C 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
90° to the strap.
7.5.5. 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 simultaneously 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.
7.5.6. 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.
7.6. 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% 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.

7.7. 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 2.14.6. 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 either as
defined in Paragraph 7.7.1 or 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 Paragraph 7.7.1.2 to 7.7.1.6.
Alternatively, in the case where those devices cannot be tested on the test trolley, the
manufacturer may demonstrate by a conventional frontal impact test at 50 km/h in
conformity with the procedure ISO 3560 (1975) that the device complies with the
requirements of the Regulation.
7.7.1.2. 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.
7.7.1.3. 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.
7.7.1.4. The seats of the vehicle 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 the report. The seat back, if adjustable for
inclination, shall be locked as specified by the manufacturer or, in the absence of any
specification, to an actual seat back angle as near as possible to 25° in the case of vehicles
of Categories M and N as near as possible to 15° in the case of vehicles of all other
categories.

7.7.4.2. Acceleration Test Device
The trolley shall be so propelled that its total velocity change ΔV is 51 km/h km/h. The
trolley shall remain horizontal during the acceleration. The acceleration of the trolley shall
be achieved by using the apparatus complying with the performance hereafter specified:
The acceleration curve of the trolley, weighted with inert mass, must remain within the
hatched area of the graph in Annex 8, and stay above the segment defined by the
coordinates 10g, 5 ms and 20g, 10 ms. The start of the impact (T0) is defined, according to
ISO 17 373 (2005) for a level of acceleration of 0.5g. 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 acceleration test device, trolley’s total
velocity change ΔV shall be 51 km/h km/h.
Despite the fulfilment of the above requirements, the technical service shall use a mass of
trolley (equipped with its seat), as specified in Paragraph 1 of Annex 6, greater than 380 kg.
7.7.5. The trolley speed immediately before impact (only for deceleration trolleys, needed for
stopping distance calculation), the trolley acceleration or deceleration, the forward
displacement of the manikin and the speed of the chest at a 300 mm displacement of the
chest shall be measured.
The velocity change will be calculated by integration of the recorded trolley acceleration or
deceleration.
The distance to achieve the first 50 km/h km/h of the velocity change of the trolley may be
calculated by double integration of the recorded trolley deceleration.
7.7.6. 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.
7.7. However, if the tests were performed at a higher speed and/or the acceleration curve have
exceeded the upper level of the hatched area and the safety belt meets the requirements,
the test shall be considered satisfactory.

7.10. Test Report
7.10.1. The test report shall record:
(a)
(b)
(c)
(d)
(e)
(f)
(g)
(h)
(i)
the results of all the tests in Paragraph 7 above and in particular:
the type of device used for the test (acceleration or deceleration device),
the total velocity change,
the trolley speed immediately before impact only for deceleration trolleys,
the acceleration or deceleration curve during all the velocity change of the trolley,
the maximum forward displacement of the manikin,
the place - if it can be varied - occupied by the buckle during the test,
the buckle-opening force,
any failure or breakage.
If by virtue of Paragraph 7.7.1. the anchorages prescribed in Annex 6 to this Regulation
have not been respected, the test report shall describe how the belt assembly or the
restraint system was installed and shall specify important angles and dimensions.
The report shall also mention any distortion or breakage of the buckle that has occurred
during the test. In the case of a restraint system the test report shall also specify the
manner of attaching the vehicle structure to the trolley, the position of the seats, and the
inclination of the seat backs. If the forward displacement of the manikin has exceeded the
values prescribed in Paragraph 6.4.1.3.2. above, the report shall state whether the
requirements of Paragraph 6.4.1.4.1. have been met.
8. REQUIREMENTS CONCERNING THE INSTALLATION IN THE VEHICLE
8.1. Vehicle Equipment
8.1.1. With the exception of folding seats (as defined in Regulation No. 14) and seating intended

1.2. Description of the Manikin
1.2.1. Structure of the Lower Leg (See Figures 3 and 4)
The structure of the lower leg consists of three components:
a sole plate (30);
a shin tube (29); and
a knee tube (26).
The knee tube has two lugs which limit the movement of the lower leg in relation to the
thigh.
The lower leg can be rotated rearwards 120° from the straight position.

1.2.9. Overalls
The manikin is covered by a special overall (see Table 1).
2. CORRECTION DEVICES
2.1. General
3. CUSHION
In order to calibrate the manikin to certain values and its total mass, the mass distribution
are adjusted by the use of six correction steel masses of 1 kg each, which can be mounted
at the hip joint. Six polyurethane weights each of 1 kg mass can be mounted in the back of
the torso.
A cushion must be positioned between the chest of the manikin and the overall. This
cushion shall be made of polyethylene foam of the following specification:
Hardness
7-10 shore A
Thickness: 25 mm ± 5
It shall be replaceable.
4. ADJUSTMENT OF THE JOINTS
4.1. General
4.2. Knee Joint
4.3. Hip Joint
In order to achieve reproducible results, it is necessary to specify and control the friction at
each joint.
Tighten the knee joint.
Set the thigh and lower leg vertical.
Rotate the lower leg through 30°.
Gradually slacken the tensioner (28) until the lower leg starts to fall under its own mass.
Lock the tensioner in this position.
Tighten the hip joint.
Place the thigh in a horizontal position and the torso in a vertical position.
Rotate the torso in a forward direction until the angle between the torso and the thigh is 60°.
Gradually slacken the tensioner until the torso starts to fall under its own mass.
Lock the tensioner in this position.

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.
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. "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;
2.3. "'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. "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):
2.7. "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;

3.2.5. 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.
4. PROCEDURE FOR "H" POINT AND ACTUAL TORSO ANGLE DETERMINATION
4.1. The vehicle shall be preconditioned at the manufacturer's discretion, at a temperature of
20 ± 10° C to ensure that the seat material reached room temperature. If the seat to be
checked has never been sat upon, a 70 or 80 kg person or device shall sit on the seat twice
for 1 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. 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.
4.4. 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 cm and weighing 0.228 kg/m 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 as the floor of the vehicle in
which the seat is intended to be used.
4.5. 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.
4.6. 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.

4.12. 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 10° arc (5° 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.
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. 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.

ANNEX 15 – 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.
