ANNEX 4
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 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)

3.2.4. 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.
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 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 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)
(b)
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
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. 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
test.

ANNEX 4 - 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.

All dimensions are in millimetres
