5.4.3.

Location of the effective upper belt anchorages (see annex 3)

5.4.3.1.

If a strap guide or similar device is used which affects the location of the effective upper belt
anchorage, this location shall be determined in a conventional way by considering the position of
the anchorage when the longitudinal centre line of the strap passes through a point J1 defined suc-
cessively from the R point by the following three segments:

RZ:

ZX:

XJ1:

a segment of the torso line measured in an upward direction from R and 530 mm long;

a segment perpendicular to the median longitudinal plane of the vehicle, measured from
point Z in the direction of the anchorage and 120 mm long;

a segment perpendicular to the plane defined by segments RZ and ZX, measured in a for-
ward direction from point X and 60 mm long.

Point J2 is determined by symmetry with point J1 about the longitudinal vertical plane passing
through the torso line described in paragraph 5.1.2 of the manikin positioned in the seat in
question.

Where a two-door configuration is used to provide access to both the front and rear seats and the
upper anchorage is fitted to the ‘B’ post, the system must be designed so as not to impede access
to or egress from the vehicle.

longitudinal median plane of the seat and makes an angle of 65° with the torso line. The angle
may be reduced to 60° in the case of rear seats. The plane FN shall be so placed as to intersect
the torso line at a point D such that DR = 315 mm + 1,8 S. However, when S ≤ 200 mm, then
DR = 675 mm.

The effective upper belt anchorage shall lie behind a plane FK running perpendicular to the lon-
gitudinal median plane of the seat and intersecting the torso line at an angle of 120° at a point B
such that BR = 260 mm + S. Where S ≥ 280 mm, the manufacturer may use BR = 260 mm + 0,8 S
at his discretion.

5.4.3.4.

The value of S shall not be less than 140 mm.

5.4.3.5.

The effective upper belt anchorage shall be situated to the rear of a vertical plane perpendicular to
the median longitudinal plane of the vehicle and passing through the R point as shown in annex 3.

6.2.1.

6.2.2.

6.2.3.

The method used to secure the vehicle during the test shall not be such as to strengthen the seat
belt anchorages or the Isofix anchorages and their anchorage area or to lessen the normal defor-
mation of the structure.

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 to be tested and is held or fixed at the rear
not less than 300 mm from that anchorage.

It is recommended that the structure should rest on supports arranged approximately in line with
the axes of the wheels or, if that is not possible, in line with the points of attachment of the
suspension.

6.2.4.

If a securing method other than that prescribed in paragraphs 6.2.1 to 6.2.3 of this Regulation is
used, evidence must be furnished that it is equivalent.

6.3.

General test requirements for seat belt anchorages

6.3.1.

6.3.2.

All the belt anchorages of the same group of seats shall be tested simultaneously. However, if there
is a risk that non-symmetrical loading of the seats and/or anchorages may lead to failures, an addi-
tional test may be carried out with non-symmetrical loading.

The tractive force shall be applied in a direction corresponding to the seating position at an angle
of 10 degrees ± 5° above the horizontal in a plane parallel to the median longitudinal plane of the
vehicle.

A preload of 10 per cent with a tolerance of ± 30 per cent of the target load shall be applied; the
load shall be increased to 100 per cent of the relevant target load.

6.3.3.

Full application of the load shall be achieved as rapidly as possible, and within a maximum load
application time of 60 seconds.

However, the manufacturer may request the application of the load to be achieved within
4 seconds.

The belt anchorages must withstand the specified load for not less than 0,2 second.

6.3.4.

Traction devices to be used in the tests described in paragraph 6.4 below are shown in annex 5.
The devices shown in Annex 5, figure 1 are placed onto the seat cushion and then, when possible,
pushed back into the seat back while the belt strap is pulled tight around it. The device shown in
Annex 5, figure 2 is placed in position, the belt strap is fitted over the device and pulled tight. No
preload beyond the minimum necessary for correct positioning of the test device shall be intro-
duced to safety-belt anchorages during this operation.

The traction device of either 254 mm or 406 mm used at each seating position shall be such that
its width is as close as possible to the distance between the lower anchorages.

The positioning of the traction device shall avoid any mutual influences during the pull test which
adversely affects the load and load distribution.

The anchorage points shall be tested according to the forces prescribed in paragraphs 6.4.1, 6.4.2
or 6.4.3, as appropriate. In each case the test load shall correspond to the load prescribed for M3
or N3 vehicles.

6.4.6.2.

The test load shall be directed forward in relation to the seating position in question, correspond-
ing to the procedure prescribed in paragraph 6.3.

6.5.

In the case of a group of seats as described in paragraph 1 of Annex 7, the dynamic test of Annex 7
can be performed, at the option of the car manufacturer, as an alternative to the static test pre-
scribed in paragraphs 6.3 and 6.4.

6.6.

Static test requirements

6.6.1.

The strength of the Isofix anchorage systems shall be tested applying the forces, as prescribed in
paragraph 6.6.4.3, to the static force application device (SFAD) with Isofix attachments well
engaged.

In case of Isofix top tether anchorage an additional test shall be performed as prescribed in
paragraph 6.6.4.4.

All the Isofix positions of a same seat row, which can be used simultaneously, shall be tested
simultaneously.

6.6.2.

The test may be carried out either on a completely finished vehicle or on sufficient parts of the
vehicle so as to be representative of the strength and rigidity of the vehicle structure.

Windows and doors may be fitted or not and closed or not.

Any fitting normally provided and likely to contribute to the vehicle structure may be fitted.

The test may be restricted to the Isofix position relating to only one seat or group of seats on the
condition that:

(a) The Isofix position concerned has the same structural characteristics as the Isofix position

relating to the other seats or group of seats and,

(b) Where such Isofix positions are fitted totally or partially on the seat or group of seats, the
structural characteristics of the seat or group of seats are the same as those for the other seats
or groups of seats.

6.6.3.

If the seats and head restraint are adjustable, they shall be tested in the position defined by the tech-
nical service within the limited range prescribed by the car manufacturer as provided in appen-
dix 3 of Annex 17 of Regulation No 16.

6.6.4.

Forces, directions and excursion limits

6.6.4.1.

A force of 135 N ± 15 N shall be applied to the centre of the lower front crossbar of the SFAD in
order to adjust the fore-aft position of the SFAD rearward extension to remove any slack or ten-
sion between the SFAD and its support.

S e a t

i n e r t i a f o r c e s

For the installation position where the load is transferred into a vehicle seat assembly, and not
directly into the vehicle structure, a test shall be carried out to ensure that the strength of the
vehicle seat anchorages to the vehicle structure is sufficient. In this test, a force equal to 20 times
the mass of the relevant parts of the seat assembly shall be applied horizontally and longitudinally
in a forward direction to the seat or the relevant part of the seat assembly corresponding to the
physical effect of the mass of the seat in question to the seat anchorages. The determination of the
additional applied load or loads and the load distribution shall be made by the manufacturer and
agreed by the technical service.

At the request of the manufacturer, the additional load can be applied at the X point of SFAD dur-
ing the static tests described above.

If the top tether anchorage is integrated to the vehicle seat, this test shall be performed with the
Isofix top tether strap.

No breakage shall occur and excursion requirements given in the table 2 have to be fulfilled.

Note: This test does not have to be performed in case of any anchorage of the vehicle safety-belt
system is integrated to the vehicle seat structure, and the vehicle seat is already tested and approved
to meet the anchorage load tests required by this Regulation for adult passenger restraint.

INSPECTION DURING AND AFTER STATIC TESTS FOR SAFETY-BELT ANCHORAGES

All the anchorages shall be capable of withstanding the test prescribed in paragraphs 6.3. and 6.4.
Permanent deformation, including partial rupture or breakage of any anchorage or surrounding
area, shall not constitute failure if the required force is sustained for the specified time. During the
test, the minimum spacings for the effective lower belt anchorages specified in paragraph 5.4.2.5
and the requirements of paragraph 5.4.3.6 for effective upper belt anchorages shall be respected.

For vehicles of category M1 of a total permissible mass not exceeding 2,5 tonnes, if the upper
safety-belt anchorage is attached to the seat structure, the effective upper safety-belt anchorage
shall not be displaced during the test forward of a transverse plane passing through the R point
and point C of the seat in question (see figure 1 of Annex 3 to this Regulation)

For vehicles other than mentioned above, the effective upper safety-belt anchorage shall not be dis-
placed during the test forward of a transverse plane inclined 10° in forward direction and passing
through the R point of the seat.

The maximum displacement of the effective upper anchorage point shall be measured during the
test.

If the displacement of the effective upper anchorage point exceeds the above-mentioned limita-
tion, the manufacturer shall demonstrate to the satisfaction of the technical service that there is no
danger to the occupant. As an example, the test procedure according to Regulation No 94 or a
sled test with corresponding pulse may be carried out to demonstrate a sufficient survival space.

In vehicles where such devices are used, the displacement and locking devices enabling the occu-
pants of all seats to leave the vehicle must still be operable by hand after the tractive force was
removed.

After testing any damage to the anchorages and structures supporting load during tests shall be
noted.

By derogation, the upper anchorages fitted to one or more seats of vehicles of category M3 and
those of category M2 with a maximum mass exceeding 3,5 tonnes, which meet the requirements
of Regulation No 80, need not to comply with the requirements of paragraph 7.1 concerning com-
pliance with paragraph 5.4.3.6.

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

ANNEX 4

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 specifica-
tions 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 seat-
ing 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 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 provi-
sions 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 para-
graph 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 inter-
sect at the ‘R’ point, and if the actual torso angle is within 5° 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.

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 require-
ments 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 to 80 kg per-
son 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 min 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 speci-
fied 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 test is run on a seat outside the
vehicle, the floor on which the seat is placed shall have the same essential characteristics (1) as the floor of the
vehicle in which the seat is intended to be used.

(1) Tilt angle, height difference with a seat mounting, surface texture, etc.

L 321/30

EN

Official Journal of the European Union

6.12.2007

4.5.

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.

If the 3-D H machine tends to slide rearward, use the following procedure. Allow the 3-D H machine to slide rear-
ward 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.

4.9.2.

If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine rear-
wards 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).

4.10.

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 care-
fully 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° 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.

6.12.2007

Official Journal of the European Union

L 321/31

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 rock-
ing motions. Care shall be exercised in holding the T-bar and rocking the 3-D H machine to ensure that no inad-
vertent 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.

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 mini-
mum period of 30 min 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.

(*) For details of the construction of the 3-D H machine refer to Society of Automobile Engineers (SAE), 400 Commonwealth Drive, War-

rendale, Pennsylvania 15096, United States of America.
The machine corresponds to that described in ISO Standard 6549:1980.

THREE-DIMENSIONAL REFERENCE SYSTEM

1.

2.

3.

The three-dimensional reference system is defined by three orthogonal planes established by the vehicle manufacturer
(see figure) (*).

The vehicle measuring attitude is established by positioning the vehicle on the supporting surface such that the
co-ordinates of the fiducial marks correspond to the values indicated by the manufacturer.

The co-ordinates of the ‘R’ point and the ‘H’ point are established in relation to the fiducial marks defined by the vehicle
manufacturer.

REFERENCE DATA CONCERNING SEATING POSITIONS

1.

Coding of reference data

Reference data are listed consecutively for each seating position. Seating positions are identified by a two-digit code.
The first digit is an Arabic numeral and designates the row of seats, counting from the front to the rear of the vehicle.
The second digit is a capital letter, which designates the location of the seating position in a row, as viewed in the
direction of forward motion of the vehicle; the following letters shall be used:

L = left

C = centre

R = right

ANNEX 7

DYNAMIC TEST AS AN ALTERNATIVE TO THE SAFETY-BELT ANCHORAGES
STATIC STRENGTH TEST

1.

SCOPE

This annex describes a dynamic sled test that can be performed as an alternative to the safety-belt anchorages static
strength test prescribed in paragraphs 6.3 and 6.4 of this Regulation.

This alternative can apply at the request of the car manufacturer in the case of a group of seats where all the seat-
ing positions are equipped with 3-point safety-belts to which thorax load limiter functions are associated and when
the group of seats additionally comprises a seating position for which the upper safety-belt anchorage is located
on the seat structure.

2.

PRESCRIPTIONS

2.1.

In the dynamic test prescribed in paragraph 3. of this annex, there shall be no rupture of any anchorage or sur-
rounding area. A programmed rupture necessary for the functioning of the load limiter device is however
permitted.

The minimum spacings for the effective lower anchorages specified in paragraph 5.4.2.5 of this Regulation, and
the requirements for the effective upper anchorages specified in paragraph 5.4.3.6 of this Regulation and, when
applicable, completed by the following paragraph 2.1.1, shall be respected.

2.1.1.

For vehicles of category M1 of a total permissible mass not exceeding 2,5 tonnes, the upper safety-belt anchorage,
if attached to the seat structure, shall not be displaced forward of a transverse plane passing through the R point
and point C of the seat in question (see figure 1 of Annex 3 to this Regulation).

For vehicles other than mentioned above, the upper safety-belt anchorage shall not be displaced forward of a trans-
verse plane inclined 10° in forward direction and passing through the R point of the seat.

2.2.

2.3.

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

The vehicle owner’s manual shall include indications that each safety-belt shall only be replaced by an approved
safety-belt for the considered seating position in the vehicle, and shall in particular identify those seating positions
which may only be fitted with an appropriate safety-belt equipped with a load limiter.

3.

DYNAMIC TEST CONDITIONS

3.1.

General conditions

The general conditions described in paragraph 6.1 of this Regulation apply to the test described in this annex.

3.2.

Installation and preparation

3.2.1.

Sled

The sled must be so constructed that no permanent deformation appears after the test. It must be so guided that,
during the impact phase, the deviation does not exceed 5° in the vertical plane and 2° in the horizontal plane.

3.2.2.

Securing of the vehicle structure

The part of the vehicle structure considered essential for the vehicle rigidity regarding the seat anchorages and the
safety-belt anchorages shall be secured on the sled, according to the disposals described in paragraph 6.2 of this
Regulation.

L 321/42

EN

Official Journal of the European Union

6.12.2007

3.2.3.

Restraint systems

3.2.3.1. The restraint systems (the complete seats, the safety-belt assemblies and the load limiter devices) shall be mounted

on the vehicle structure according to the series production vehicle specifications.

The vehicle environment facing the tested seat (dashboard, seat, etc., depending on the tested seat) can be mounted
on the test sled. If there were a frontal airbag, it has to be deactivated.

3.2.3.2. At the request of the car manufacturer and in agreement with the technical service in charge of the tests, some
components of the restraint systems other than the complete seats, the safety-belt assemblies and the load limiter
devices, may not be mounted on the test sled or may be replaced by components having equivalent or lower stiff-
ness and whose dimensions are comprised in the vehicle interior fittings dimensions, provided that the tested con-
figuration is at least as unfavourable as the series configuration regarding the forces applying to the seat and safety-
belt anchorages.

3.2.3.3. The seats shall be adjusted as required in paragraph 6.1.2 of this Regulation, in the position for use chosen by the
technical service in charge of the tests as the one giving the most adverse conditions regarding the anchorages
strength and compatible with the installation of the dummies in the vehicle.

3.2.4.

Dummies

A dummy whose dimensions and mass are defined in Annex 8 shall be positioned on each seat and restrained by
the safety-belt provided in the vehicle.

No dummy instrumentation is required.

3.3.

Test

3.3.1.

The sled shall be so propelled that, during the test, its speed variation is 50 km/h. The sled deceleration shall be
within the corridor specified in Annex 8 of Regulation No 16.

3.3.2.

If applicable, the activation of additional restraining devices (preloading devices, etc., except airbags) is triggered
according to the car manufacturer’s indications.

3.3.3.

It shall be checked that the safety-belt anchorages’ displacement does not exceed the limits specified in para-
graphs 2.1 and 2.1.1 of this annex.
