PROCEDURE FOR DETERMINING THE "H" POINT AND THE ACTUAL
TORSO ANGLE FOR SEATING POSITIONS IN MOTOR VEHICLES
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.
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 l to
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
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 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 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. 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
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
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 spirits 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:
return the back pan to the seat-back;
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
4.14. Take all measurements:
4.14.1. The co-ordinates of the "H" Point are measured with respect to the three-dimensional
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 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
ANNEX 3 - 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.

ANNEX 4 - APPENDIX 2
THE PROCEDURE FOR CALCULATING THE VISCOUS CRITERION FOR EUROSID 1
The Viscous Criterion, VC, is calculated as the instantaneous product of the compression and the rate of
deflection of the rib. Both are derived from the measurement of rib deflection. The rib deflection
response is filtered once at Channel Frequency Class 180. The compression at time (t) is calculated as
the deflection from this filtered signal expressed as the proportion of the half width of the EUROSID 1
chest, measure at the metal ribs (0.14 metres):
The rib deflection velocity at time (t) is calculated from the filtered deflection as:
[ − D ] − [ D − D ]
12 ∂ t
where D is the deflection at time (t) in metres and ∂t is the time interval in seconds between the
measurements of deflection. The maximum value of ∂t shall be 1,25 x 10 seconds.
This calculation procedure is shown diagrammatically below:
188.8.131.52. Blocks 1, 2 and 3 should be crushed by 10 ± 2 mm on the top surface prior to testing to give
a depth of 500 ± 2 mm (Figure 2).
184.108.40.206. Blocks 4, 5 and 6 should be crushed by 10 ± 2 mm on the top surface prior to testing to give
a depth of 440 ± 2 mm.

220.127.116.11. The cell dimensions shall be 19 mm ± 10% for each block (see Figure 4).
18.104.22.168. The cells must be made of 3003 aluminium for the upper row.
22.214.171.124. The cells must be made of 5052 aluminium for the lower row.
126.96.36.199. The aluminium honeycomb blocks should be processed such that the force deflection-curve
when statically crushed (according to the procedure defined in Paragraph 2.1.4) is within the
corridors defined for each of the six blocks in Appendix 1 to this Annex. Moreover, the
processed honeycomb material used in the honeycomb blocks to be used for constructing
the barrier, should be cleaned in order to remove any residue that may have been produced
during the processing of the raw honeycomb material.
188.8.131.52. The mass of the blocks in each batch shall not differ by more than 5% of the mean block
mass for that batch.
2.1.4. Static Tests
184.108.40.206. A sample taken from each batch of processed honeycomb core shall be tested according to
the static test procedure described in Paragraph 5.
220.127.116.11. The force-compression for each block tested shall lie within the force deflection corridors
defined in Appendix 1. Static force-deflection corridors are defined for each block of the
2.1.5. Dynamic Test

impactor - as defined in Appendix 2 - may be allowed provided that:
126.96.36.199.1. The deviation occurs after the beginning of the impact and before the deformation of the
impactor is equal to 150 mm;
188.8.131.52.2. The deviation does not exceed 50% of the nearest instantaneous prescribed limit of the
184.108.40.206.3. Each deflection corresponding to each deviation does not exceed 35 mm of deflection, and
the sum of these deflections does not exceed 70 mm (see Appendix 2 to this Annex);
220.127.116.11.4. The sum of energy derived from deviating outside the corridor does not exceed 5% of the
gross energy for that block.

184.108.40.206. The test piece should be 100 mm x 100 mm, and 15 mm deep, bonded to a sample of the
ventilated back plate material. The honeycomb used should be representative of that in the
impactor, i.e. chemically etched to an equivalent degree as that near to the back plate in the
barrier but without pre-crushing.
2.6.1. Impactors shall carry consecutive serial numbers which are stamped, etched or otherwise
permanently attached, from which the batches for the individual blocks and the date of

2.7.1. The fitting on the trolley must be according to Figure 8. The fitting will use six M8 bolts, and
nothing shall be larger than the dimensions of the barrier in front of the wheels of the
trolley. Appropriate spacers must be used between the lower back plate flange and the
trolley face to avoid bowing of the back plate when the attachment bolts are tightened.
4.4. Examples of Sampling According to Batch
4.4.1. If several examples of one block type are constructed from one original block of aluminium
honeycomb and are all treated in the same treatment bath (parallel production), one of
these examples could be chosen as the sample, provided care is taken to ensure that the
treatment is evenly applied to all blocks. If not, it may be necessary to select more than one
4.4.2. If a limited number of similar blocks (say three to twenty) are treated in the same bath (serial
production), then the first and last block treated in a batch, all of which are constructed from
the same original block of aluminium honeycomb, should be taken as representative
samples. If the first sample complies with the requirements but the last does not, it may be
necessary to take further samples from earlier in the production until a sample that does
comply is found. Only the blocks between these samples should be considered to be
4.4.3. Once experience is gained with the consistency of production control, it may be possible to
combine both sampling approaches, so that more than one groups of parallel production
can be considered to be a batch provided samples from the first and last production groups

5.5. The data acquisition for static compression shall be sampled at a minimum of 5 Hz.
5.6. The static test shall be continued until the block compression is at least 300 mm for blocks 4
to 6 and 350 mm for blocks 1 to 3.
6. DYNAMIC TESTS

against a dynamometric wall supported by a fixed rigid barrier, according to the method
6.1.1. Testing Ground
220.127.116.11. The test area shall be large enough to accommodate the run-up-track of the mobile
deformable barrier, the rigid barrier and the technical equipment necessary for the test. The
last part of the track, for at least 5 metres before the rigid barrier, shall be horizontal, flat and
18.104.22.168. The central accelerometer shall be located within 500 mm of the location of the centre of

permanently attached, from which the batches for the individual blocks and the date of
manufacture can be established.
6.6. Data Processing Procedure
6.6.1. Raw data: At time T = T , all offsets should be removed from the data. The method by
which offsets are removed shall be recorded in the test report.
188.8.131.52. The raw data will be filtered prior to processing/calculations.

6.6.3. Calculation of MDB Face Deflection
22.214.171.124. Accelerometer data from all three accelerometers individually (after filtering at CFC 180),
will be integrated twice to obtain deflection of the barrier deformable element.

220.127.116.11. Compare the total energy change to the change in kinetic energy of the MDB, given by:
E = MV
where V is the impact velocity and M the whole mass of the MDB.
If the momentum change (M*ΔV) is not equal to the total impulse (I) ± 5%, or if the total
energy absorbed (Σ E ) is not equal to the kinetic energy, E ± 5%, then the test data must
be examined to determine the cause of this error.

following installation procedure.
2.1. Adjust the knee and ankle joints so that they just support the lower leg and the foot when
extended horizontally (1 to 2 g − adjustment).
2.2. Check if the dummy is adapted to the desired impact direction.
2.3. The dummy shall be clothed in a form-fitting cotton stretch mid-calf length pant and may be
clothed in a form-fitting cotton stretch shirt with short sleeves.
2.4. Each foot shall be equipped with a shoe.
2.5. Place the dummy in the outboard front seat on the impacted side as described in the side impact
test procedure specification.
2.6. The plane of symmetry of the dummy shall coincide with the vertical median plane of the
specified seating position.
2.7. The pelvis of the dummy shall be positioned such that a lateral line passing through the dummy
H-Points is perpendicular to the longitudinal centre plane of the seat. The line through the
dummy H-Points shall be horizontal with a maximum inclination of ± 2° .
The correct position of the dummy pelvis can be checked relative to the H-point of the H-point
