Height of head restraints

5.5.1.

The height of head restraints shall be measured as described in paragraph 6.5.

5.5.2.

For head restraints not adjustable for height, the height shall be not less than 800 mm in the case of
front seats and 750 mm in the case of other seats.

5.5.3.

For head restraints adjustable for height:

5.5.3.1.

the height shall be not less than 800 mm in the case of front seats and 750 mm in the case of other
seats; this value shall be obtained in a position between the highest and lowest positions to which
adjustment is possible;

5.5.3.2.

there shall be no ‘use position’ resulting in a height of less than 750 mm;

5.5.3.3.

in the case of seats other than the front seats the head restraints may be such that they can be
displaced to a position resulting in a height of less than 750 mm, provided that such position is
clearly recognizable to the occupant as not being included for the use of the head restraint;

5.5.3.4.

in the case of front seats head restraints may be such that they can be automatically displaced when
the seat is not occupied, to a position resulting in a height of less than 750 mm, provided that they
automatically return to the position of use when the seat is occupied.

5.5.4.

The dimensions mentioned in paragraphs 5.5.2. and 5.5.3.1. may be less than 800 mm in the case
of front seats and 750 mm in the case of other seats to leave adequate clearance between the head
restraint and the interior surface of the roof, the windows or any part of the vehicle structure;
however, the clearance shall not exceed 25 mm. In the case of seats fitted with displacement and/or
adjustment systems,
this shall apply to all seat positions. Furthermore, by derogation to
paragraph 5.5.3.2, there shall not be any ‘use position’ resulting in a height lower than 700 mm.

5.7.

There shall be no gap of more than 60 mm between the seat-back and the head restraint in the case
of a device not adjustable for height. If the head restraint is adjustable for height it shall, in its lowest
position, be not more than 25 mm from the top of the seat-back. In the case of seats or bench seats
adjustable in height provided with separate head restraints, this requirement shall be verified for all
the positions of the seat or bench seat.

5.8.

In the case of head restraints integral with the seat-back, the area to be considered is:

above a plane perpendicular to the reference line at 540 mm from the R point.

Between two vertical longitudinal planes passing at 85 mm on either side of the reference line. In
this area, one or more gaps which regardless of their shape can show a distance ‘a’ of more than
60 mm when measured as described in paragraph 6.7., are permitted provided that, after the
additional test under paragraph 6.4.3.3.2, the requirements of paragraph 5.11. are still met.

In the case of head restraints adjustable for height one or more gaps, which regardless of their shape
can show a distance ‘a’ of more than 60 mm when measured as described in paragraph 6.7, are
permitted on the part of the device serving as a head restraint provided that, after the additional test
under paragraph 6.4.3.3.2, the requirements of paragraph 5.11. are still met.

The width of the head restraint shall be such as to provide appropriate support for the head of a
person normally seated. As determined according to the procedure described in paragraph 6.6, the
head restraint shall cover an area extending not less than 85 mm to each side of the vertical median
plane of the seat for which the head restraint is intended.

The head restraint and its anchorage shall be such that the maximum backward displacement X of
the head permitted by the head restraint and measured in conformity with the static procedure laid
down in paragraph 6.4.3, is less than 102 mm.

The head restraint and its anchorage shall be strong enough to bear without breakage the load
specified in paragraph 6.4.3.6. In the case of head restraints integral with the seat-back, the
requirements of this paragraph shall apply to the part of the seat-back structure situated above a
plane perpendicular to the reference line at 540 mm from the R point.

If the head restraint is adjustable,
it shall not be possible to raise it beyond the maximum
operational height except by deliberate action on the part of the user distinct from any act necessary
for its adjustment.

The strength of the seat-back and of its locking devices is deemed to meet the requirements set out
in paragraph 6.2. when, after testing in accordance with paragraph 6.4.3.6., no breakage of the seat
or seat-back has occurred; otherwise, it shall be shown that the seat is capable of meeting the test
requirements set out in paragraph 6.2.

Special requirements regarding the protection of occupants from displaced luggage

5.15.1.

Seat-backs

Seat-backs and/or head restraints located such that they constitute the forward boundary of the
luggage compartment, all seats being in place and in the normal position of use as indicated by the
manufacturer, shall have sufficient strength to protect the occupants from displaced luggage in a
frontal impact. This requirement is deemed to be met if, during and after the test described in
Annex 9, the seat-backs remain in position and the locking mechanisms remain in place. However,

11.5.2007

Official Journal of the European Union

L 121/11

the deformation of the seat-backs and their fastenings during the test is permitted, provided that the
forward contour of the parts of the tested seat-back and/or head restraints, that are harder than 50
Shore A, does not move forward of a transverse vertical plane which passes through:

(a)

a point of 150 mm forward of the R point of the seat in question, for the parts of the head
restraint;

(b)

a point of 100 mm forward of the R point of the seat in question, for parts of the seat-back;

excluding the rebound phases of the test blocks.

For integrated head restraints, the limit between the head restraint and the seat-back is defined by
the plane perpendicular to the reference line 540 mm from the R point.

All measurements shall be taken in the longitudinal median plane of the corresponding seat or
seating position for each seating position constituting the forward boundary of the luggage
compartment.

During the test described in Annex 9, the test blocks shall remain behind the seat-back(s) in
question.

5.15.2.

Partitioning systems

At the request of the vehicle manufacturer, the test described in Annex 9 may be carried out with
the partitioning systems in place, if these systems are fitted as standard equipment for the particular
type of vehicle.

Partitioning systems, netting wire mesh located above the seat-backs in their normal position of
use, shall be tested according to paragraph 2.2. of Annex 9.

This requirement is deemed to be met if, during the test, the partitioning systems remain in
position. However, the deformation of the partitioning systems during the test is permitted,
provided that the forward contour of the partitioning (including parts of the tested seat-back(s)
and/or head restraint(s) that are harder than 50 Shore A does not move forward of a transverse
vertical plane which passes through:

(a)

(b)

a point of 150 mm forward of the ‘R’ point of the seat in question, for parts of the head
restraint;

a point of 100 mm forward of the ‘R’ point of the seat in question, for parts of the seat-back
and part of the partitioning system others than the head restraint.

For integrated head restraint, the limit between the head restraint and the seat-back is the one
defined in paragraph 5.15.1.

All measurements shall be taken in the longitudinal median plane of the corresponding seat or
seating position for each seating position constituting the forward boundary of the luggage
compartment.

After the test, no sharp or rough edges likely to increase the danger or severity of injuries of the
occupants shall be present.

5.15.3.

The requirements mentioned in paragraphs 5.13.1. and 5.13.2. shall not apply to luggage retention
systems which are activated automatically in case of an impact. The manufacturer shall demonstrate
to the satisfaction of the technical service that the protection offered by such systems is equivalent
to that described in paragraphs 5.15.1. and 5.15.2.

TESTS

General specifications applicable to all tests

The seat-back, if adjustable, shall be locked in a position corresponding to a rearward inclination as
close as possible to 25o from the vertical of the torso reference line of the manikin described in
Annex 3, unless otherwise specified by the manufacturer.

When a seat, its locking mechanism and its installation are identical or symmetrical with respect to
another seat on the vehicle, the technical service may test only one such seat.

In the case of seats with adjustable head restraints, the tests shall be conducted with the head
restraints placed in the most unfavourable position (generally, the highest position) allowed by its
adjusting system.

6.3.1.

6.3.2.

6.3.3.

6.3.4.

6.3.5.

A force producing a moment of 53 daNm in relation to the R point shall be applied longitudinally
and rearwards to the upper part of the seat-back frame through a component simulating the back
of the manikin shown in Annex 3 to this Regulation. In the case of a bench seat, where part or all of
the supporting frame (including that of the head restraints) is common to more than one seating
position, the test shall be conducted simultaneously for all those seating positions.

Test of strength of the seat anchorage and the adjustment,
systems

locking and displacement

A longitudinal horizontal deceleration of not less than 20 g shall be applied for 30 milliseconds in
the forward direction to the whole shell of the vehicle, in accordance with the requirements of
Annex 7, paragraph 1. At the request of the manufacturer the test pulse described in Annex 9 —
Appendix, may be used alternatively.

A longitudinal deceleration in accordance with the requirements of paragraph 6.3.1. shall be
applied in the rearward direction.

The requirements of paragraphs 6.3.1. and 6.3.2. shall be verified for all positions of the seat. In the
case of seats fitted with an adjustable head restraint, the test shall be conducted with the head
restraints placed in the most unfavourable position (generally the highest position) allowed by its
adjusting system. During the test the seat shall be so positioned that no external factor shall prevent
the release of the locking systems.

These conditions shall be considered to be met if the seat is tested after being adjusted in the
following positions:

the longitudinal adjustment is fixed one notch or 10 mm rearward of the most forward normal
driving position or position of use as indicated by the manufacturer (for seats with independent
vertical adjustment, the cushion shall be placed in its highest position);

the longitudinal adjustment is fixed one notch or 10 mm forward of the most rearward normal
driving position or position of use as indicated by the manufacturer (for seats with independent
vertical adjustment, the cushion shall be placed in its lowest position), and, where appropriate, in
accordance with the requirements of paragraph 6.3.4.

In cases where the arrangement of the locking systems is such that, in a seat position other than
those defined in paragraph 6.3.3. the distribution of the forces on the locking devices and seat
anchorages would be less favourable than with either configuration defined in paragraph 6.3.3., the
tests shall be conducted for that less favourable seating position.

The test conditions of paragraph 6.3.1. shall be considered to be satisfied if, at the request of the
manufacturer, they are replaced by a collision test of the complete vehicle in running order against a
rigid barrier as laid down in paragraph 2. of Annex 7 to this Regulation. In this case, the seat shall
be adjusted for the least favourable conditions of distribution of stresses in the anchorage system as
provided for in paragraphs 6.1.1., 6.3.3. and 6.3.4.

Test of the performance of the head restraint

6.4.1.

6.4.2.

If the head restraint is adjustable, it shall be placed in the most unfavourable position (generally the
highest position) allowed by its adjustment system.

In the case of a bench seat, where part or all of the supporting frame (including that of the head
restraints) is common to more than one seating position, the test shall be conducted simultaneously
for all those seating positions.

6.4.3.

Test

6.4.3.1. All lines, including the projections of the reference line, shall be drawn in the vertical median plane

of the seat or seating position concerned (see Annex 5 to this Regulation).

6.4.3.2.

The displaced reference line is determined by applying to the part simulating the back of the
manikin referred to in Annex 3 to this Regulation an initial force producing a rearward moment of
37,3 daNm about the R point.

6.4.3.3.

By means of a spherical headform 165 mm in diameter an initial force producing a moment of
37,3 daNm about the R point is applied at right angles to the displaced reference line at a distance
of 65 mm below the top of the head restraint, the reference line being kept in its displaced position
in accordance with paragraph 6.4.3.2.

6.4.3.3.1. If the presence of gaps prevents the application of the force prescribed in paragraph 6.4.3.3. at
65 mm from the top of the head restraint, the distance may be reduced so that the axis of the force
passes through the centre line of the frame element nearest to the gap.

6.4.3.3.2. In the cases described in paragraphs 5.8. and 5.9., the test shall be repeated by applying to each gap,

using a sphere of 165 mm in diameter, a force:

passing through the centre of gravity of the smallest of the sections of the gap, along transversal
planes parallel to the reference line, and

reproducing a moment of 37,3 daNm about the R point.

6.4.3.4.

The tangent Y to the spherical headform, parallel to the displaced reference line, is determined.

6.4.3.5.

The distance X, provided for in paragraph 5.11., between the tangent Y and the displaced reference
line is measured.

6.4.3.6.

To check the effectiveness of the head restraint, the initial load specified in paragraphs 6.4.3.3. and
6.4.3.3.2. is increased to 89 daN unless the breakage of the seat or seat-back occurs earlier.

6.5.

Determination of the height of the head restraint

6.5.1.

6.5.2.

6.5.3.

All lines, including the projection of the reference line, shall be drawn in the vertical median plane
of the seat or seating position concerned, the intersection of such plane with the seat determining
the contour of the head restraint and of the seat-back (see figure 1 of Annex 4 to this Regulation).

The manikin described in Annex 3 to this Regulation shall be placed in a normal position on the
seat.

The projection of the reference line of the manikin shown in Annex 3 to this Regulation is then, in
the seat concerned, drawn in the plane specified in paragraph 6.4.3.1.

The tangent S to the top of the head restraint is drawn perpendicular to the reference line.

6.5.4.

The distance ‘h’ from the R point to the tangent S is the height to be taken into consideration in
implementing the requirements of paragraph 5.5.

Determination of the width of the head restraint (see figure 2 of Annex 4 to this
Regulation)

The plane S1, perpendicular to the reference line and situated 65 mm below the tangent S defined
in paragraph 6.5.3, determines a section in the head restraint bounded by the outline C.

The width of the head restraint to be taken into consideration in implementing the requirements of
paragraph 5.10., is the distance ‘L’ measured in the plane S1 between the vertical longitudinal
planes P and P'.

The width of the head restraint shall if necessary also be determined in the plane perpendicular to
the reference line 635 mm above the R point of the seat, this distance being measured along the
reference line.

6.7.

Determination of distance ‘a’ of head restraint gaps (see Annex 8 to this Regulation)

6.7.1.

The distance ‘a’ shall be determined for each gap and in relation to the front face of the head
restraint, by means of a sphere having a diameter of 165 mm.

6.7.2.

The sphere shall be put into contact with the gap in a point of the gap area which allows the
maximum sphere intrusion, considering no load is to be applied.

6.7.3.

The distance between the two points of contact of the sphere with the gap will constitute the
distance ‘a’ to be considered for the evaluation of the provisions under paragraphs 5.8. and 5.9.

6.8.

Tests for checking energy dissipation on the seat-back and head restraint

6.8.1.

The surfaces of the rear parts of seats to be checked are those situated in the areas defined below
which can be contacted by a 165 mm diameter sphere when the seat is mounted in the vehicle.

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

ANNEX 3

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 thigh of the 3-D H machine installed in the vehicle seat in
accordance with paragraph 4. 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.). 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.);

‘Design torso angle’ means the angle measured 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;

‘Centre plane 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 centre
plane of the seat coincides with the centre plane of the occupant. For other seats, the centre plane 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 coordinates 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.

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 coordinates 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.

3.2.

Relationship between measured data and design specifications

3.2.1.

3.2.2.

The coordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in
paragraph 4. shall be compared, respectively, with the coordinates 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 coordinates, 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 five degrees 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. 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. shall apply.

If the results of at least two of the three operations described in paragraph 3.2.4. do not satisfy the requirements of
paragraph 3.2.2., 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 reaches 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.

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 be then 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 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 texture, etc.

4.5.

4.6.

Place the seat and back assembly of the 3-D H machine so that the centre plane of the occupant (C/LO) coincides
with the centre plane 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 centre plane 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 centre plane 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 centre plane 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. 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 10 degrees arc (5 degrees to each side of the vertical centre plane) 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 coordinates 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 drivers 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 stimulate 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.

(*)

For details of the construction of the 3-D H machine refer to Society of Automotive Engineers (SAE), 400 Commonwealth Drive,
Warrendale, Pennsylvania 15096, United States of America.
The machine corresponds to that described in ISO Standard 6549: 1980.

2.1.1.1. At the option of the car manufacturer, parts whose hardness is lower than 50 Shore A can be removed from the

tested seat and head restraint for the tests.

2.1.1.2. Two type 1 test blocks shall be placed on the floor of the luggage compartment. In order to determine the location
of the test blocks in the longitudinal direction, they shall first be positioned such that their front side contacts that
part of the vehicle which constitutes the forward boundary of the luggage compartment and that their lower side
rests on the floor of the luggage compartment. They shall then be moved backwards and parallel to the
longitudinal median plane of the vehicle until their geometrical centre has traversed a horizontal distance of
200 mm. If the dimensions of the luggage compartment do not allow a distance of 200 mm and if the rear seats
are horizontally adjustable, these seats shall be moved forward to the limit of the adjustment range intended for
normal occupant use, or to the position resulting in a distance of 200 mm, whichever is less. In other cases, the
test blocks shall be placed as far as possible behind the rear seats. The distance between the longitudinal median
plane of the vehicle and the inward facing side of each test block shall be 25 mm to obtain a distance of 50 mm
between both blocks.

2.1.1.3. During the test, the seats must be adjusted to ensure that the locking system cannot be released by external factors.

If applicable, the seats shall be adjusted as follows:

The longitudinal adjustment shall be secured one notch or 10 mm in front of the rearmost possible position of use
specified by the manufacturer (for seats with independent vertical adjustment, the cushion shall be placed to its
lowest possible position). The test shall be carried out with the seat-backs in their normal position of use.

2.1.1.4.

If the seat-back is fitted with a head restraint, the test must be carried out with the head restraint placed in the
highest position, if adjustable.

2.1.2.1.

If the rearmost row of seats is removable and/or can be folded down by the user according to the manufacturer's
instructions in order to increase the luggage compartment area, then the seat row immediately in front of this
rearmost row shall also be tested.

2.1.2.2. However, in this case, the Technical Service, after consultation with the manufacturer, may decide not to test one of
the two rearmost rows of seats if the seats and their attachments are of similar design and if the test requirement of
200 mm is respected.

2.1.3. When there is a gap, allowing sliding of one type 1 block past the seats, then the test loads (two type 1 blocks) shall

be installed behind the seats after agreement between the Technical Service and the manufacturer.

2.1.4.

The exact test configuration shall be noted in the test report.

Test of partitioning systems

For the test of the partitioning systems above the seat-backs, the vehicle shall be fitted with a fixed raised test floor
having a load surface that locates the centre of gravity of the test block centrally between the top edge of the
bordering seat-back (without taking into account the head restraints) and the bottom edge of the roof lining. A
type 2 test block is placed on the raised test floor with its largest surface 500 x 350 mm, centrally in relation to the
longitudinal axis of the vehicle and with its surface 500 x 125 mm to the front. Partitioning systems behind which
the type 2 test block cannot be installed are exempted from this test. The test block is placed directly in contact
with the partitioning system. In addition, two type 1 test blocks are positioned in accordance with paragraph 2.1.
in order to perform a simultaneous test on the seat-backs (see figure 2).
