Projections, Pursuant to Regulation No. 61.
Annex 2 – Arrangements of Approval Marks
Annex 3

Procedure for Determining the "H" Point and the Actual Seat-back Angle and for
Verifying their Relationship to the "R" Point and the Design Seat-back Angle
Annex 4 – Measurement of Projections and Distances

2.7. "Floor line" means a line determined as follows:
When a vertical-axis cone of undetermined height having its side at an angle of 15° to the
vertical is moved about the external surface of the loaded vehicle so as to remain in contact
with the external surface of the body at its lowest point, the floor line is the geometrical trace
of the points of contact. In determining the floor line, no account shall be taken of the
exhaust pipes or wheels, or of functional mechanical features attached to the under-body
such as jacking points, suspension mountings or attachments for use in towing or in case of
breakdown. In the spaces at the outside of wheel arches an imaginary surface extending the
adjacent external surfaces without change of position shall be assumed. The front bumpers
shall be taken into account in determining the floor line. Depending on the type of vehicle,
the trace of the floor line may be at either the outer edge of the bumper profile or at the body
panel below the bumper. Where there are two or more points of contact at the same time,
the lowest point of contact shall be used to determine the floor line;
2.8. "Radius of curvature" means the radius of the arc of a circle which comes closest to the
rounded form of the component under consideration.
2.9. "Bumper" means the front, lower, outer structure of a vehicle. It includes all structures that
are intended to give protection to a vehicle when involved in a low speed frontal collision and
also any attachments to this structure.
2.10 "Bumper Cover" means the non-rigid outer surface of a bumper, generally extending
across the full width of the front of a vehicle.
3. APPLICATION FOR APPROVAL
3.1. The application for approval of a vehicle type with regard to external projections shall be
submitted by the vehicle manufacturer or by his duly accredited representative.
3.2. It shall be accompanied by the undermentioned documents in triplicate:
3.2.1. photographs of the front and side parts of the vehicle,
3.2.2. such drawing of the "external surface" which in the opinion of the technical service
responsible for conducting the tests are required in order to demonstrate compliance with
the provisions of Paragraphs 5. and 6. below.
3.3. The applicant shall submit to the technical service responsible for conducting the approval
test:
3.3.1. either a vehicle representative of the type to be approved or the part(s) of the vehicle
deemed essential to carry out the checks and tests required in this Regulation,
3.3.2. certain parts and samples of the materials used, if so required by the technical service.
4. APPROVAL
4.1. If the vehicle submitted for approval pursuant to this Regulation meets the requirements of
Paragraphs 5. and 6. below, approval of that vehicle type shall be granted. Subject to the
acceptance of the Technical Service and to the satisfaction of the Type Approval Authority, a
vehicle of Category N which is derived from Category M may be type approved on the
basis of technical specifications of Regulation No. 26.

5. GENERAL SPECIFICATIONS
5.1. The provisions of this Regulation shall not apply to those parts of the "external surface" of
the vehicle which, with the vehicle in the unladen condition, with doors, windows, access
lids, etc., in the closed position are either:
5.1.1. outside a zone having as its upper limit a horizontal plane situated 2.00m above the ground
and as its lower limit either the reference plane defined in Paragraph 2.6. or the floor line
defined in Paragraph 2.7. as selected by the manufacturer, or
5.1.2. located so that, in static condition, they cannot be contacted by a sphere 100mm diameter.
5.1.3. Where the reference plane is the lower limit of the zone, account shall be taken only of the
parts of the vehicle falling between two vertical planes, one touching the external surface of
the vehicle and the other parallel to it at a distance of 80mm towards the interior of the
vehicle.
5.2. The "external surface" of the vehicle shall not exhibit, directed outwards, any part likely to
catch on pedestrians, cyclists or motor cyclists.
5.3. Any components specified in Paragraph 6. below, shall not exhibit, directed outwards, any
pointed or sharp parts or any projections of such shape, dimensions, direction or hardness
as to be likely to increase the risk or seriousness of bodily injury to a person hit by the
external surface or brushing against it in the event of a collision.
5.4. Projecting parts of the outer surface having a hardness of not more than 60 Shore A, may
have a radius of curvature lower than the values prescribed under Paragraph 6. below.
6. SPECIFIC REQUIREMENTS
6.1. Ornaments, commercial symbols, letters and numbers of commercial markings
6.1.1. Ornaments, commercial symbols, letters and numbers of commercial markings shall not
have any radius of curvature of less than 2.5mm. This requirement does not apply to these
parts if they do not protrude more than 5mm from the surrounding surface; however, in this
case their edges directed outwards shall be blunted.
6.1.2. Ornaments, commercial symbols, letters and numbers of commercial markings, which
project more than 10mm from the surrounding surface shall retract, become detached or
bend over under a force of 10daN exerted at their most salient point in any direction in a
plane approximately parallel to the surface on which they are mounted.
To apply 10daN force a flat-ended ram of not more than 50mm diameter shall be used.
Where this is not possible, an equivalent method shall be used. After the ornaments are
retracted, detached or bent over, the remaining portion shall not project more than 10mm
and shall not have any pointed, sharp or cutting edges.

ANNEX 3
PROCEDURE FOR DETERMINING THE "H" POINT AND THE ACTUAL
SEAT-BACK ANGLE AND FOR VERIFYING THEIR RELATIONSHIP
TO THE "R" POINT AND THE DESIGN SEAT-BACK ANGLE
1. DEFINITIONS
1.1. The "H" point, which indicates the position of a seated occupant in the passenger
compartment, is the trace, in a longitudinal vertical plane, of the theoretical axis of rotation
between the legs and the torso of a human body represented by the manikin described in
Paragraph 3 below.
1.2. The "R" point or "seating reference point" is the reference point specified by the
manufacturer which:
1.2.1. has co-ordinates determined in relation to the vehicle structure;
1.2.2. corresponds to the theoretical position of the point of torso/legs rotation ("H" point) for the
lowest and most rearward normal driving position or position of use given to each seat
provided by the vehicle manufacturer.
1.3. "Seat-back angle" means the inclination of the seat back in relation to the vertical.
1.4. "Actual seat-back angle" means the angle formed by the vertical through the "H" point with
the torso reference line of the human body represented by the manikin described in
Paragraph 3 below.
1.5. "Design seat-back angle" means the angle prescribed by the manufacturer which:
1.5.1. determines the seat-back angle for the lowest and most rearward normal driving position or
position of use given to each seat by the vehicle manufacturer;
1.5.2. is formed at the "R" point by the vertical and the torso reference line;
1.5.3. corresponds theoretically to the actual seat-back angle.
2. DETERMINATION OF "H" POINTS AND ACTUAL SEAT-BACK ANGLES
2.1. An "H" point and an "actual seat-back angle" shall be determined for each seat provided by
the manufacturer. If the seats in the same row can be regarded as similar (bench seat,
identical seats, etc.) only one "H" point and one "actual seat-back angle" shall be determined
for each row of seats, the manikin described in Paragraph 3 below being seated in a place
regarded as representative for the row. This place shall be:
2.1.1. in the case of the front row, the driver's seat;
2.1.2. in the case of the rear row or rows, an outer seat.

4.4.2. In the rear seats, so far as possible in such a way as to be in contact with the front seats. 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 point and the other foot shall be so
arranged that the level enabling the transverse orientation of the seat of the manikin to be
verified is brought to the horizontal;
4.4.3. If the "H" point is being determined at a centre seat, the feet shall be placed one on each
side of the tunnel;
4.5. The masses shall be placed on the thighs, the level verifying the transverse orientation of
the seat of the manikin shall be brought to the horizontal, and the weights shall be placed on
the component representing the seat of the manikin;
4.6. The manikin shall be moved away from the seat back by means of the knee-pivot bar and
the back of the manikin shall be pivoted forwards. The manikin shall be repositioned on the
seat of the vehicle by being slid backwards on its seat until resistance is encountered, the
back of the manikin then being replaced against the seat back;
4.7. A horizontal load of approximately 10 ± 1 daN shall be applied to the manikin twice. The
direction and point of application of the load are shown by a black arrow in Figure 2;
4.8. The masses shall be installed on the right and left sides and the torso weights shall then be
placed in position. The transverse level of the manikin shall be kept horizontal;
4.9. The transverse level of the manikin being kept horizontal, the back of the manikin shall be
pivoted forwards until the torso weights are above the "H" point, so as to eliminate any
friction with the seat back;
4.10. The back of the manikin shall be gently moved rearwards so as to complete the setting-up
operation. The transverse level of the manikin shall be horizontal. If it is not, the procedure
above shall be repeated.
5. RESULTS
5.1. When the manikin has been set up as described in Paragraph 4 above, the "H" point and the
actual seat-back angle of the vehicle seat in question are constituted by the "H" point and
the angle of inclination of the manikin's torso reference line.
5.2. The co-ordinates of the "H" point in relation to three mutually perpendicular planes, and the
actual seat-back angle, shall be measured for comparison with the data supplied by the
vehicle manufacturer.

ANNEX 4
MEASUREMENT OF PROJECTIONS AND DISTANCES
1. METHOD OF DETERMINING THE DIMENSIONS OF THE PROJECTION OF A PART
FITTED ON THE EXTERNAL SURFACE
1.1. The dimensions of the projection of a part mounted on a convex panel may be determined
either directly or by reference to a drawing of an appropriate section of the part in the fitted
position.
1.2. If the projection of a part mounted on a panel other than convex cannot be determined by
simple measurement, it shall be determined by the maximum variation in the distance
between the reference line of the panel and the centre of a sphere of 100 mm diameter
when the sphere is moved in constant contact with the part. An example of the use of this
method is given in Figure 1.
1.3. For grab handles, the projection shall be measured in relation to a plane passing through the
point of attachment. An example is given in Figure 2.
2. METHOD OF DETERMINING THE PROJECTION OF HEADLAMP VISORS AND RIMS
2.1. The projection from the outer surface of the headlamp shall be measured horizontally from
the point of contact of a sphere of 100 mm diameter, as shown in Figure 3.
3. METHOD OF DETERMINING THE DISTANCE BETWEEN PARTS OF GRILLE
3.1. The distance between parts of a grille shall be the distance between two planes passing
through the points of contact of the sphere and perpendicular to the line joining the points of
contact. Examples of the use of this method are given in Figures 4 and 5.
