5.5.4.   The head restraints 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 attachments to the seat-back as a result of the pressure exerted by the headform during the test.

5.5.5.   In the case of a seat fitted with head restraints, the provisions of paragraph 5.2.3 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 5.5.2 above.

5.6.   Height of head restraints

5.6.1.   The height of head restraints shall be measured as described in paragraph 6.5 below.

5.6.2.   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.

5.6.3.   For head restraints adjustable for height:

5.6.3.1.   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;

5.6.3.2.   There shall be no ‘use position’ resulting in a height of less than 750 mm;

5.6.3.3.   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 recognisable to the occupant as not being included for the use of the head restraint;

5.6.3.4.   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.

5.6.4.   The dimensions mentioned in paragraphs 5.6.2 and 5.6.3.1 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 5.6.3.2 above, there shall not be any ‘use position’ resulting in a height lower than 700 mm.

5.6.5.   By derogation to the height requirements mentioned in paragraphs 5.6.2 and 5.6.3.1 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.

5.7.   In the case of a seat capable of being fitted with a head restraint, the provisions of paragraphs 5.2.3 and 5.5.2 above shall be verified.

5.7.1.   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.

5.8.   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.

5.9.   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 5.12 below are still met.

5.10.   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 5.12 below are still met.

5.11.   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.

5.12.   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.

5.13.   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 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.

5.14.   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.

5.15.   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.

5.16.   Special requirements regarding the protection of occupants from displaced luggage

5.16.1.   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; |
| --- | --- |

(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; |
| --- | --- |

(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. In case of damage to a safety-belt retractor, it shall be verified that the retractor is locked as a result of the test or that it can be locked by a manual pull out of the strap.

5.16.2.   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.

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; |
| --- | --- |

(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. |
| --- | --- |

(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 5.16.1.

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. In case of damage to a safety-belt retractor, it shall be verified that the retractor is locked already or that it can be locked by a manual pull out of the strap.

5.16.3.   The requirements mentioned in paragraphs 5.16.1. and 5.16.2. 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 5.16.1. and 5.16.2.

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.

6.1.4.   Folding seats shall be tested in the position of use by occupants.

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.

6.3.   Test of strength of the seat anchorage and the adjustment, locking and displacement systems.

6.3.1.   A longitudinal horizontal deceleration or, at the choice of the applicant, acceleration of not less than 20 g shall be applied for 30 milliseconds in a direction to the whole shell of the vehicle imitating a frontal collision, 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 or, at the choice of the applicant, acceleration in accordance with the requirements of paragraph 6.3.1 shall be applied imitating a rear collision.

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 above, the tests shall be conducted for that less favourable seating position.

6.3.5.   The test conditions of paragraph 6.3.1 above 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).

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. In the case of simultaneous testing of bench seats, the rear ward moment shall be applied to all seating positions of the bench simultaneously, irrespective of this position being equipped with or without head restraint.

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 above. In the case of simultaneous testing of bench seats, the force shall be applied to all head restraints as present on the bench seats simultaneously.

6.4.3.3.1.   If the presence of gaps prevents the application of the force prescribed in paragraph 6.4.3.3 above 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 5.9 and 5.10 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. At the request of the manufacturer the load of paragraph 6.4.3.2 is increased simultaneously to 53 daNm for seating positions without head restraints only to allow simultaneous compliance with paragraphs 5.15 and 6.2.

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 5.6 above.

6.6.   Determination of the width of the head restraint (see Figure 2 of Annex 4 to this Regulation)

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 5.11 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 5.9 and 5.10 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.

6.8.1.1.3.   In the case of seats or bench seats with head restraints, this area shall extend between the longitudinal vertical planes, on either side of and 70 mm from the longitudinal median plane of the seat or of the seating position concerned and situated above the plane perpendicular to the reference line 635 mm from the R point. For the test, the head restraint, if adjustable shall be placed in the most unfavourable position (generally the highest) permitted by its adjustment system.

6.8.1.2.   Area 2

6.8.1.2.1.   In the case of seats or bench seats without head restraints and seats or bench seats with detachable or separate head restraints, area 2 shall extend above a plane perpendicular to the reference line 100 mm distant from the top of the seat-back, other than parts of area 1.

6.8.1.2.2.   In the case of seats or bench seats with integrated head restraints, area 2 shall extend above a plane perpendicular to the reference line 440 mm distant from the R point of the seat or of the seating position concerned, other than parts of area 1.

6.8.1.3.   Area 3

6.8.1.3.1.   Area 3 is defined as the part of the back of the seat or the bench seats situated above the horizontal planes defined in paragraph 5.2.4.1.3 above, excluding parts situated in area 1 and area 2.

6.9.   Equivalent test methods

If a test method other than those specified in paragraphs 6.2, 6.3, 6.4 above and Annex 6 is used, its equivalence shall be proved.

7.   CONFORMITY OF PRODUCTION

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 (*1) 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.

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 accelerometers.

3.   Equivalent procedures (see paragraph 6.9 of this Regulation).

---

(*1)  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:

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 shall 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.

2.1.1.4.   If the seat-back is fitted with a head restraint, the test shall 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.

2.1.1.7.   All seating positions of the seat row under test shall be fitted with all components of its safety-belt providing the restraining function that are part of the seat.

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 × 350 mm, centrally in relation to the longitudinal axis of the vehicle and with its surface 500 × 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 shall 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 decelerated or, at the choice of the applicant, accelerated such that the curve remains within the area of the graph in Annex 9, Appendix, and the total velocity change ΔV 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 of this Regulation.

Formula

in which t1 and t2 are any values of time during the test, HIC being maximum value for an interval t1, t2. The values of t1 and t2 are expressed in seconds.

1.2.   Thorax acceptability criterion (ThAC)

1.2.1.   This criterion is determined by the absolute value of resultant acceleration, expressed in g and measured according to Appendix 3, paragraph 2.2.2, and by the acceleration period, expressed in ms.

1.3.   Femur acceptability criterion (FAC)

This criterion is determined by the compression load expressed in kN, transmitted axially on each femur of the manikin and measured according to Appendix 3, paragraph 2.2.3, and by the duration of the compression load, expressed in ms.

2.   Side impact (side-facing seat)

2.1.   Head injury criterion (HIC) see above paragraph 1.1.

2.2.   Thorax acceptability criterion

2.2.1.   Chest deflection: the peak chest deflection is the maximum value of deflection on any rib as determined by the thorax displacement transducers.

2.2.2.   Viscous criterion (VC):

The peak viscous response is the maximum value of VC on any rib which is calculated from the instantaneous product of the relative thorax compression related to the half thorax and the velocity of compression derived by differentiation of the compression. For the purposes of this calculation the standard width of the half thorax rib cage is 140 mm.

Formula

where D (metres) = rib deflection

The calculation algorithm to be used is set out in Regulation No 95, Annex 4, Appendix 2.

2.3.   Abdomen acceptability criterion

The peak abdominal force is the maximum value of the sum of the three forces measured by transducers mounted 39 mm below the surface on the crash side.

2.4.   Pelvis acceptability criterion

The pubic symphysis peak force (PSPF) is the maximum force measured by a load cell at the pubic symphysis of the pelvis.

APPENDIX 7

Requirements for the safeguarding of passengers in side-facing seats according to paragraph 7.4.4

1.   The distance between the foremost side-facing seat and the vehicle part forward of this foremost side-facing seat shall not exceed 450 mm. All measurements are to be taken 1 000 mm above the reference plane of the foremost side-facing seat (see Figure 1).

Figure 1

Positioning requirements for side-facing seats

2.   The vehicle part (e.g. partition, wall or seat back of a forward facing seat) in front of the foremost side-facing seat shall fulfil the following requirements in order to safeguard the passenger in that foremost side-facing seat (see Figure 2):

2.1.   The height of the vehicle part, based on the reference plane of the foremost side-facing seat, must not be less than 1 020 mm; and

2.2.   The effective impact surface of the vehicle part has a width of 200 mm and a height of 580 mm. This surface shall be positioned so that the vertical centre-line is located 50 mm behind the H-point of the foremost side-facing seat; and

2.3.   The corresponding surface of the vehicle part in place projected onto a vertical plane through this H-point, shall cover at least 95 per cent of the effective impact surface. This vehicle part shall fulfil the energy absorption requirement by Appendix 6.

2.3.1.   If there is a gap in the corresponding surface (typically two forward-facing seats with a gap in between) a distance shall be determined for each gap by means of a sphere having a diameter of 165 mm. 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. The distance between the two points of contact of the sphere must be less than 60 mm;

3.   At the manufacturers' choice, a test according to Appendix 1 with the appropriate manikin for side-facing seats may be conducted.
