5.4.        Special requirements for seats fitted or capable of being fitted with head restraints
5.4.1.      The presence of the head restraint must not be an additional cause of danger to occupants of
            the vehicle. In particular, it shall not in any position of use exhibit any dangerous roughness
            or sharp edge liable to increase the risk or seriousness of injury to the occupants.
5.4.2.      Parts of the front and rear faces of the head restraints situated in area 1, as defined in
            paragraph 6.8.1.1.3. below shall pass the energy absorption test.
5.4.2.1.    This requirement is deemed to be met if in the tests carried out by the procedure specified in
            annex 6 the deceleration of the headform does not exceed 80 g continuously for more than
            3 ms. Moreover, no dangerous edge shall occur during or remain after the test.
5.4.3.      Parts of the front and rear faces of head restraints situated in area 2, as defined in
            paragraph 6.8.1.2.2. below, shall be so padded as to prevent any direct contact of the head
            with the components of the structure and shall meet the requirements of paragraph 5.1.4.
            above applicable to the rear parts of seats situated in area 2.
5.4.4.      The requirements of paragraphs 5.4.2. and 5.4.3. above, shall not apply to parts of rear faces
            of head restraints designed to be fitted to seats behind which no seat is provided.
5.4.5.      The head restraint shall be secured to the seat or to the vehicle structure in such a way that
            no rigid and dangerous parts project from the padding of the head restraint or from its
            attachment to the seat-back as a result of the pressure exerted by the headform during the
            test.
5.4.6.      In the case of a seat fitted with a head restraint, the provisions of paragraph 5.1.3. may, after
            agreement of the technical service, be considered to be met if the seat fitted with its head
            restraint complies with the provisions of paragraph 5.4.2. above.
5.5.        Height of head restraints
5.5.1.     The height of head restraints shall be measured as described in paragraph 6.5. below.
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.
 ---pagebreak--- L 373/10     EN                  Official Journal of the European Union                          27.12.2006
5.5.4.   The dimensions mentioned in paragraphs 5.5.2. and 5.5.3.1. above 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. above, there shall not be any "use position"
         resulting in a height lower than 700 mm.
5.5.5.   By derogation to the height requirements mentioned in paragraphs 5.5.2. and 5.5.3.1. above,
         the height of any head restraint designed to be provided in rear centre seats or seating
         positions shall be not less than 700 mm.
5.6.      In the case of a seat capable of being fitted with a head restraint, the provisions of
          paragraphs 5.1.3. and 5.4.2. above shall be verified.
5.6.1.    The height of the part of the device on which the head rests, measured as described in
          paragraph 6.5. below, shall in the case of a head restraint adjustable for height be not less
          than 100 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. below, are permitted
          provided that, after the additional test under paragraph 6.4.3.3.2. below, the requirements of
          paragraph 5.11. below are still met.
5.9.      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. below, 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. below, the requirements of
          paragraph 5.11. below are still met.
5.10.     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. below, 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.
5.11.     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. below, is less than 102 mm.
5.12.     The head restraint and its anchorage shall be strong enough to bear without breakage the
          load specified in paragraph 6.4.3.6. below. In the case of head restraints integral with the
 ---pagebreak--- 27.12.2006    EN                  Official Journal of the European Union                             L 373/11
           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.
5.13.       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.
5.14.       The strength of the seat-back and of its locking devices is deemed to meet the requirements
            set out in paragraph 6.2. below when, after testing in accordance with paragraph 6.4.3.6.
            below, 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. below.
5.15.       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, 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.
 ---pagebreak--- L 373/12     EN                 Official Journal of the European Union                          27.12.2006
          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)      a point of 150 mm forward of the R point of the seat in question, for 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 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. above 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.
6.       TESTS
6.1.     General specifications applicable to all tests
6.1.1.   The seat-back, if adjustable, shall be locked in a position corresponding to a rearward
         inclination as close as possible to 25° from the vertical of the torso reference line of the
         manikin described in annex 3, unless otherwise specified by the manufacturer.
6.1.2.   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.
6.1.3.   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.
6.2.     Test of strength of the seat-back and its adjustment systems
6.2.1.   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.
 ---pagebreak--- 27.12.2006     EN                 Official Journal of the European Union                              L 373/13
6.3.       Test of strength of the seat anchorage and the adjustment, locking and displacement systems
6.3.1.     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.
6.3.2.     A longitudinal deceleration in accordance with the requirements of paragraph 6.3.1. shall be
           applied in the rearward direction.
6.3.3.     The requirements of paragraphs 6.3.1. and 6.3.2. above 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. below.
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. above, 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.
6.3.5.     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.
           above.
6.4.       Test of the performance of the head restraint
6.4.1.     If the head restraint is adjustable, it shall be placed in the most unfavourable position
           (generally the highest position) allowed by its adjustment system.
6.4.2.     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).
 ---pagebreak--- L 373/14       EN                Official Journal of the European Union                           27.12.2006
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. above, 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. above, 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.     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).
6.5.2.     The manikin described in annex 3 to this Regulation shall be placed in a normal position on
           the seat.
6.5.3.     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. above.
           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. above.
6.6.       Determination of the width of the head restraint
           (see figure 2 of annex 4 to this Regulation)
 ---pagebreak--- 27.12.2006    EN                  Official Journal of the European Union                            L 373/15
6.6.1.     The plane S1, perpendicular to the reference line and situated 65 mm below the tangent S
           defined in paragraph 6.5.3. above, determines a section in the head restraint bounded by the
           outline C.
6.6.2.     The width of the head restraint to be taken into consideration in implementing the
           requirements of paragraph 5.10. above, is the distance "L" measured in the plane S1
           between the vertical longitudinal planes P and P'.
6.6.3.     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. above.
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.
6.8.1.1.    Area 1
6.8.1.1.1.  In the case of separate seats without head restraints, this area shall include the rear part of
            the seat-back between the longitudinal vertical planes situated at 100 mm on either side of
            the longitudinal median plane of the seat centre line, and above a plane perpendicular to
            the reference line 100 mm below the top of the seat-back.
6.8.1.1.2.  In the case of bench seats without head restraints, this area shall extend between the
            longitudinal vertical planes situated at 100 mm on either side of the longitudinal median
            plane of each designated outboard seating position defined by the manufacturer and above
            a plane perpendicular to the reference line 100 mm below the top of the seat-back.

9.1.       Every modification of the vehicle type with respect to the seats, their anchorages and/or
           their head restraints shall be notified to the administrative department which approved the
           vehicle type. The department may then either:
9.1.1.     consider that the modifications made are unlikely to have an appreciable adverse effect, and
           that in any event the vehicle still complies with the requirements; or
9.1.2.     consider that the modifications are sufficiently unimportant for the results specified in
           paragraph 6.2., 6.3. and 6.4. above to be verified by calculations based on the approval test
           results; or
9.1.3.      require a further report from the technical service responsible for conducting the tests.
9.2.        Confirmation or refusal of approval, specifying the modifications, shall be communicated
            to the Parties to the Agreement applying this Regulation by means of the procedure laid
            down in paragraph 4.3. above.
9.3.        The competent authority issuing the extension of approval shall assign a series number for
            such an extension and inform thereof the other Parties to the 1958 Agreement applying this
            Regulation by means of a communication form conforming to the model in annex 1 to this

                 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. 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.             "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 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 and the torso line using the back angle quadrant on the 3-D H machine. The actual

3.       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 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.   The co-ordinates of the "H" point and the value of the actual torso angle obtained by the
         procedure set out in paragraph 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.
3.2.2.   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 intersect at the "R"
         point, and if the actual torso angle is within 5 degree 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.   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 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. 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 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.
4.5.            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.
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 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
2/     Tilt angle, height difference with a seat mounting, surface texture, etc.
 ---pagebreak--- L 373/28      EN                 Official Journal of the European Union                           27.12.2006
          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. 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 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.
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 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).
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 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.
 ---pagebreak--- 27.12.2006     EN                 Official Journal of the European Union                             L 373/29
           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 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.      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.
4.16.      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;
 ---pagebreak--- L 373/30    EN                 Official Journal of the European Union 27.12.2006

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.

                        TEST PROCEDURE FOR CHECKING ENERGY DISSIPATION
1.                Installation, test apparatus, recording instruments and procedure
1.1.              Setting up
                  The seat, as mounted in the vehicle, shall be firmly secured to the test bench with the
                  attachment parts provided by the manufacturer, so as to remain stationary when the impact
                  is applied.
                  The seat-back, if adjustable, shall be locked in the position specified in paragraph 6.1.1. of
                  this Regulation.
                  If the seat is fitted with a head restraint, the head restraint shall be mounted on the seat-back
                  as in the vehicle. Where the head restraint is separate, it shall be secured to the part of the
                  vehicle structure to which it is normally attached.
                  If the head restraint is adjustable, it shall be placed in the most unfavourable position
                  allowed by its adjusting systems.
1.2.              Test apparatus
1.2.1.            This apparatus consists of a pendulum whose pivot is supported by ball-bearings and whose
                  reduced mass ∗/ at its centre of percussion is 6,8 kg. The lower extremity of the pendulum
                  consists of a rigid headform 165 mm in diameter whose centre is identical with the centre of
                  percussion of the pendulum.
1.2.2.            The headform shall be fitted with two accelerometers and a speed-measuring device, all
                  capable of measuring values in the direction of impact.
1.3.              Recording instruments
                  The recording instruments used shall be such that measurements can be made with the
                  following degrees of accuracy:
1.3.1.           Acceleration:
                          accuracy = + 5 % of the actual value;
                          frequency class of data channel: class 600 corresponding to
                          ISO Standard 6487 (1980);
                          cross-axis sensitivity = < 5 % of the lowest point on the scale.
∗/      The relationship of the reduced mass "mr" of the pendulum to the total mass "m" of the pendulum at a distance
"a" between the centre of percussion and the axis of rotation and at a distance "l" between the centre of gravity and
the axis of rotation is given by the formula:
                                                                   l
                                                        mr = m
                                                                   a

1.3.2.      Speed:
                    accuracy: + 2,5 % of the actual value;
                    sensitivity: 0,5 km/h.
1.3.3.      Time recording:
            the instrumentation shall enable the action to be recorded throughout its duration and
            readings to be made to within one one-thousandth of a second;
            the beginning of the impact at the moment of first contact between the headform and the
            item being tested shall be detected on the recordings used for analysing the test.
1.4.        Test procedure
1.4.1.      Tests on the seat-back
            With the seat installed as indicated in paragraph 1.1. of this annex, the direction of impact
            from the rear towards the front shall be situated in a longitudinal plane at an angle of 45°
            from the vertical.
            The impact points shall be selected by the test laboratory in area 1 as defined in paragraph
            6.8.1.1. of this Regulation, or if necessary in area 2 as defined in paragraph 6.8.1.2. of this
            Regulation, on surfaces exhibiting radii of curvature less than 5 mm.
1.4.2.      Tests on the head restraint
            The head restraint shall be fitted and adjusted as indicated in paragraph 1.1. of this annex.
            Impacts shall be performed on points selected by the test laboratory in area 1 as defined in
            paragraph 6.8.1.1. of this Regulation, and possibly in area 2 as defined in paragraph 6.8.1.2.
            of this Regulation, on surfaces exhibiting radii of curvature less than 5 mm.
1.4.2.1.   For the rear face, the direction of impact from the rear towards the front shall be in a
           longitudinal plane at an angle of 45° from the vertical.
1.4.2.2.    For the front face, the direction of impact from the front towards the rear shall be horizontal
            in a longitudinal plane.
1.4.2.3.    The front and rear zones are respectively bounded by the horizontal plane tangential to the
            top of the head restraint as determined in paragraph 6,5. of this Regulation.
1.4.3.      The headform shall strike the test item at a speed of 24,1 km/h: this speed shall be achieved
            either by the mere energy of propulsion or by using an additional impelling device.
2.          Results
            The deceleration rate shall be taken as the average of the readings on the two
            decelerometers.
3.          Equivalent procedures (see paragraph 6.9. of this Regulation).

            METHOD FOR TESTING THE STRENGTH OF SEAT ANCHORAGES
         AND THEIR ADJUSTMENT, LOCKING AND DISPLACEMENT SYSTEMS
1.        Test of resistance to inertia effects
1.1.      The seats to be tested shall be mounted on the vehicle body for which they are designed.
          This vehicle body shall be firmly anchored on a test trolley as prescribed in the following
          paragraphs.
1.2.      The method used for anchoring the vehicle body on the test trolley shall not result in a
          reinforcement of the seat anchorages.
1.3.      The seats and their parts shall be adjusted and locked as prescribed in paragraph 6.1.1. and
          in one of the positions described in paragraph 6.3.3. or 6.3.4. of this Regulation.
1.4.      If the seats of a group do not present essential differences in the sense of paragraph 2.2. of
          this Regulation, the tests prescribed in paragraphs 6.3.1. and 6.3.2. of this Regulation may
          be carried out with one seat adjusted to its foremost position and the other seat adjusted to
          its rearmost position.
1.5.      The trolley deceleration is measured with data channels of frequency class (CFC) 60
          corresponding to the characteristics of International Standard ISO 6487 (1980).
2.        Collision test of the complete vehicle against a rigid barrier
2.1.      The barrier shall consist of a block of reinforced concrete of not less than 3 m width, not
          less than 1,5 m height and not less than 0,6 m thickness. The front face shall be
          perpendicular to the final part of the run-up track and shall be covered with plywood boards
          19 ∀ 1 mm thick. At least 90 tonnes of earth shall be compressed behind the block of
          reinforced concrete. The barrier of reinforced concrete and earth may be replaced by
          obstacles having the same front surface, provided that they give equivalent results.

                 Mass:                            10 kg
2.               Test preparation
2.1.             Test of seat-backs (see figure 1)
2.1.1.           General requirements
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.
 ---pagebreak--- L 373/46         EN                  Official Journal of the European Union                          27.12.2006
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.
2.1.1.5. If the back(s) of the rear seat(s) can be folded down, they shall be secured in their upright
                 normal position by the standard locking mechanism.
2.1.1.6. Seats behind which the type 1 blocks cannot be installed are exempted from this test
                       Figure 1: Positions of test blocks before test of rear seat-backs
2.1.2.           Vehicles with more than two rows of seats
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.
2.2.             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).

               Figure 2: Testing of a partitioning system above the backrest
2.2.1.   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.
3.       Dynamic testing of seat-backs and partitioning systems used as luggage restraint systems
3.1.     The body of the passenger car shall be anchored securely to a test sled, and this
         anchorage shall not act as reinforcement for seat-backs and the partitioning system. After
         the installation of the test blocks as described in paragraph 2.1. or 2.2., the passenger car
         body shall be accelerated as shown in annex 9, appendix, so that at the moment of
         impact, its free running speed is 50 +0/-2 km/h. With the agreement of the manufacturer,
         the above described test pulse corridor can be used alternatively to fulfil the test of the
         seat strength according to paragraph 6.3.1.
