Subject to paragraphs 5.2.4.3 and 5.2.4.4, the portion of each Isofix top tether anchorage that is designed to bind with an Isofix top tether connector shall be located not further than 2 000 mm far from the shoulder reference point and within the shaded zone, as shown in figures 6 to 10 of annex 9, of the designated seating position for which it is installed, with the reference of a template described in SAE J 826 (July 1995) and shown in Annex 9, figure 5, according to the following conditions:

5.2.4.1.1.   The ‘H’ point of the template is located at the unique design ‘H’ point of the full downward and full rearward position of the seat, except that the template is located laterally midway between the two Isofix lower anchorages;

5.2.4.1.2.   The torso line of the template is at the same angle to the transverse vertical plane as the seat back in its most upright position; and

5.2.4.1.3.   The template is positioned in the vertical longitudinal plane that contains the H-point of the template.

5.2.4.2.   The Isofix top tether anchorage zone may be alternatively located with the aid of the fixture ‘ISO/F2’ (B), as defined in Regulation No 16 (Annex 17, appendix 2, figure 2), in an Isofix position equipped with Isofix low anchorages as shown in figure 11 of Annex 9.

The seating position shall be the seat's rearmost, downmost position with the seat back in its nominal position, or as recommended by the vehicle manufacturer.

In the side view, the Isofix top tether anchorage shall lie behind the ‘ISO/F2’ (B) fixture rear face.

The intersection between the ‘ISO/F2’ (B) fixture rear face and the horizontal line (Annex 9, figure 11, reference 3) containing the last rigid point of a hardness greater than 50 Shore A at the top of the seat back defines the reference point 4 (Annex 9, figure 11) on the centreline of the ‘ISO/F2’ (B) fixture. At this reference point, a maximum angle of 45° above the horizontal line defines the upper limit of the top tether anchorage zone.

In the top view, at the reference point 4 (Annex 9, figure 11), a maximum angle of 90° extending rearward and laterally and in the rear view, a maximum angle of 40° defines 2 volumes which limit the anchorage zone for the Isofix top tether.

The origin of the Isofix top tether strap (5) is located at the intersection of the ‘ISO/F2’ (B) fixture with a plane 550 mm distant above the ‘ISO/F2’ (B) fixture horizontal face (1) on the ‘ISO/F2’ (B) fixture centreline (6).

Further, the Isofix top tether anchorage shall be more than 200 mm but not more than 2 000 mm from the origin of the Isofix top tether strap on the rear face of the ‘ISO/F2’ (B) fixture, measured along the strap when it is drawn over the seat back to the Isofix top tether anchorage.

The portion of the Isofix top tether anchorage in a vehicle that is designed to bind with the Isofix top tether connector may be located outside the shaded zones referred to paragraphs 5.2.4.1 or 5.2.4.2 if a location within a zone is not appropriate and the vehicle is equipped with a routing device that:

5.2.4.3.1.   ensures that the Isofix top tether strap functions as if the portion of the anchorage designed to bind with the Isofix top tether anchorage were located within the shaded zone; and

5 kN ± 0,25 kN

Each of these tests may be performed on different structures if the manufacturer so requests.

Forces in the forward direction shall be applied with an initial force application angle of 10 ± 5° above the horizontal. Oblique forces shall be applied horizontally 0° ± 5°. A pre-load force of 500 N ± 25 N shall be applied at the prescribed loading point X indicated in figure 2 annex 9. Full application of the force shall be achieved within a period of 2 s or less. The force shall be maintained for a minimum period of 0,2 s.

All measurements shall be made according to ISO 6487 with CFC of 60 Hz or any equivalent method.

Tests of Isofix anchorages system only:

6.6.4.3.1.   Forward direction force test:

Horizontal longitudinal excursion (after pre-load) of point X of SFAD during application of the 8 kN ± 0,25 kN force shall be limited to 125 mm and permanent deformation including partial rupture or breakage of any Isofix low anchorage or surrounding area shall not constitute failure if the required force is sustained for the specified time.

6.6.4.3.2.   Oblique direction force test:

Excursion in the direction of the force (after pre-load) of point X of SFAD during application of the 5kN ± 0,25 kN force shall be limited to 125 mm and permanent deformation including partial rupture or breakage of any Isofix low anchorage or surrounding area shall not constitute failure if the required force is sustained for the specified time.

6.6.4.4.   Test of Isofix anchorages systems and Isofix top tether anchorage:

A tension pre-load of 50 N ± 5 N must be applied between the SFAD and the top-tether anchorage. Horizontal excursion (after pre-load) of point X during application of the 8 kN ± 0,25 kN force shall be limited to 125 mm and permanent deformation including partial rupture or breakage of any Isofix low anchorage and top tether anchorage, or surrounding area shall not constitute failure if the required force is sustained for the specified time.

6.6.5.   Additional forces

6.6.5.1.   Seat inertia forces

For the installation position where the load is transferred into a vehicle seat assembly, and not directly into the vehicle structure, a test shall be carried out to ensure that the strength of the vehicle seat anchorages to the vehicle structure is sufficient. In this test, a force equal to 20 times the mass of the relevant parts of the seat assembly shall be applied horizontally and longitudinally in a forward direction to the seat or the relevant part of the seat assembly corresponding to the physical effect of the mass of the seat in question to the seat anchorages. The determination of the additional applied load or loads and the load distribution shall be made by the manufacturer and agreed by the technical service.

At the request of the manufacturer, the additional load can be applied at the X point of SFAD during the static tests described above.

If the top tether anchorage is integrated to the vehicle seat, this test shall be performed with the Isofix top tether strap.

No breakage shall occur and excursion requirements given in the table 2 have to be fulfilled.

Note: This test does not have to be performed in case of any anchorage of the vehicle safety-belt system is integrated to the vehicle seat structure, and the vehicle seat is already tested and approved to meet the anchorage load tests required by this Regulation for adult passenger restraint.

Note:

7.   INSPECTION DURING AND AFTER STATIC TESTS FOR SAFETY-BELT ANCHORAGES

All the anchorages shall be capable of withstanding the test prescribed in paragraphs 6.3. and 6.4. Permanent deformation, including partial rupture or breakage of any anchorage or surrounding area, shall not constitute failure if the required force is sustained for the specified time. During the test, the minimum spacings for the effective lower belt anchorages specified in paragraph 5.4.2.5 and the requirements of paragraph 5.4.3.6 for effective upper belt anchorages shall be respected.

7.1.1.   For vehicles of category M1 of a total permissible mass not exceeding 2,5 tonnes, if the upper safety-belt anchorage is attached to the seat structure, the effective upper safety-belt anchorage shall not be displaced during the test forward of a transverse plane passing through the R point and point C of the seat in question (see figure 1 of Annex 3 to this Regulation)

1

For vehicles other than mentioned above, the effective upper safety-belt anchorage shall not be displaced during the test forward of a transverse plane inclined 10° in forward direction and passing through the R point of the seat.

The maximum displacement of the effective upper anchorage point shall be measured during the test.

If the displacement of the effective upper anchorage point exceeds the above-mentioned limitation, the manufacturer shall demonstrate to the satisfaction of the technical service that there is no danger to the occupant. As an example, the test procedure according to Regulation No 94 or a sled test with corresponding pulse may be carried out to demonstrate a sufficient survival space.

7.2.   In vehicles where such devices are used, the displacement and locking devices enabling the occupants of all seats to leave the vehicle must still be operable by hand after the tractive force was removed.

7.3.   After testing any damage to the anchorages and structures supporting load during tests shall be noted.

7.4.   By derogation, the upper anchorages fitted to one or more seats of vehicles of category M3 and those of category M2 with a maximum mass exceeding 3,5 tonnes, which meet the requirements of Regulation No 80, need not to comply with the requirements of paragraph 7.1 concerning compliance with paragraph 5.4.3.6.

ANNEX 4

PROCEDURE FOR DETERMINING THE ‘H’ POINT AND THE ACTUAL TORSO ANGLE FOR SEATING POSITIONS IN MOTOR VEHICLES

1.   PURPOSE

The procedure described in this annex is used to establish the ‘H’ point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer (1).

2.   DEFINITIONS

For the purposes of this annex:

‘Reference data’ means one or several of the following characteristics of a seating position:

2.1.1.   the ‘H’ point and the ‘R’ point and their relationship,

2.1.2.   the actual torso angle and the design torso angle and their relationship.

2.2.   
  ‘Three-dimensional “H” point machine’ (3-D H machine) means the device used for the determination of ‘H’ points and actual torso angles. This device is described in appendix 1 to this annex;

2.3.   
  ‘
  “H” point’ means the pivot centre of the torso and the thigh of the 3-D H machine installed in the vehicle seat in accordance with paragraph 4 below. The ‘H’ point is located in the centre of the centreline of the device which is between the ‘H’ point sight buttons on either side of the 3-D H machine. The ‘H’ point corresponds theoretically to the ‘R’ point (for tolerances see paragraph 3.2.2 below). Once determined in accordance with the procedure described in paragraph 4, the ‘H’ point is considered fixed in relation to the seat-cushion structure and to move with it when the seat is adjusted;

2.4.   
  ‘
  “R” point’ or ‘seating reference point’ means a design point defined by the vehicle manufacturer for each seating position and established with respect to the three-dimensional reference system;

2.5.   
  ‘Torso-line’ means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position;

2.6.   
  ‘Actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design torso angle (for tolerances see paragraph 3.2.2 below);

2.7.   
  ‘Design torso angle’ means the angle measures between a vertical line through the ‘R’ point and the torso line in a position which corresponds to the design position of the seat-back established by the vehicle manufacturer;

2.8.   
  ‘Centreplane of occupant’ (C/LO) means the median plane of the 3-D H machine positioned in each designated seating position; it is represented by the co-ordinate of the ‘H’ point on the ‘Y’ axis. For individual seats, the centreplane of the seat coincides with the centreplane of the occupant. For other seats, the centreplane of the occupant is specified by the manufacturer;

2.9.   
  ‘Three-dimensional reference system’ means a system as described in appendix 2 to this annex;

2.10.   
  ‘Fiducial marks’ are physical points (holes, surfaces, marks or indentations) on the vehicle body as defined by the manufacturer;

2.11.   
  ‘Vehicle measuring attitude’ means the position of the vehicle as defined by the co-ordinates of fiducial marks in the three-dimensional reference system.

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° 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 reached room temperature. If the seat to be checked has never been sat upon, a 70 to 80 kg person or device shall sit on the seat twice for one minute to flex the cushion and back. At the manufacturer's request, all seat assemblies shall remain unloaded for a minimum period of 30 min prior to installation of the 3-D H machine.

4.2.   The vehicle shall be at the measuring attitude defined in paragraph 2.11 above.

4.3.   The seat, if it is adjustable, shall be adjusted first to the rearmost normal driving or riding position, as indicated by the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat travel used for purposes other than normal driving or riding positions. Where other modes of seat adjustment exist (vertical, angular, seat-back, etc.) these will then be adjusted to the position specified by the vehicle manufacturer. For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving position as specified by the manufacturer.

4.4.   The area of the seating position contacted by the 3-D H machine shall be covered by a muslin cotton, of sufficient size and appropriate texture, described as a plain cotton fabric having 18,9 threads per cm2 and weighing 0,228 kg/m2 or knitted or non-woven fabric having equivalent characteristics. If test is run on a seat outside the vehicle, the floor on which the seat is placed shall have the same essential characteristics (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 centreplane of the occupant (C/LO) coincides with the centreplane of the 3-D H machine. At the manufacturer's request, the 3-D H machine may be moved inboard with respect to the C/LO if the 3-D H machine is located so far outboard that the seat edge will not permit levelling of the 3-D H machine.

4.6.   Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and lower leg assembly. A line through the ‘H’ point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat.

Adjust the feet and leg positions of the 3-D H machine as follows:

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 centreplane 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 centreplane 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.

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° arc (5° to each side of the vertical centreplane) for three complete cycles to release any accumulated friction between the 3-D H machine and the seat.

During the rocking action, the T-bar of the 3-D H machine may tend to diverge from the specified horizontal and vertical alignment. The T-bar must therefore be restrained by applying an appropriate lateral load during the rocking motions. Care shall be exercised in holding the T-bar and rocking the 3-D H machine to ensure that no inadvertent exterior loads are applied in a vertical or fore and aft direction.

The feet of the 3-D H machine are not to be restrained or held during this step. If the feet change position, they should be allowed to remain in that attitude for the moment.

Carefully return the back pan to the seat-back and check the two spirit levels for zero position. If any movement of the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows:

Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is obtained. During this lifting, the feet are to be free to rotate; and no forward or lateral loads are to be applied. When each foot is placed back in the down position, the heel is to be in contact with the structure designed for this.

Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of the back pan sufficient to level the 3-D H machine's seat pan on the seat.

4.13.   Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion, proceed as follows:

| (a) | return the back pan to the seat-back; |
| --- | --- |

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

(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.

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 min prior to the re-run. The 3-D H machine should not be left loaded on the seat assembly longer than the time required to perform the test.

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;

4.16.2.   in the case of the rear row or rows, an outer seat.

---

(1)  In any seating position other than front seats where the ‘H’ point cannot be determined using the ‘Three-dimensional “H” point machine’ or procedures, the ‘R’ point indicated by the manufacturer may be taken as a reference at the discretion of the competent authority.

(2)  Tilt angle, height difference with a seat mounting, surface texture, etc.

Appendix 1

DESCRIPTION OF THE THREE DIMENSIONAL ‘H’ POINT MACHINE (*1)

(3-D H machine)

1.   BACK AND SEAT PANS

The back and seat pans are constructed of reinforced plastic and metal; they simulate the human torso and thigh and are mechanically hinged at the ‘H’ point. A quadrant is fastened to the probe hinged at the ‘H’ point to measure the actual torso angle. An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.

2.   BODY AND LEG ELEMENTS

Lower leg segments are connected to the seat pan assembly at the T-bar joining the knees, which is a lateral extension of the adjustable thigh bar. Quadrants are incorporated in the lower leg segments to measure knee angles. Shoe and foot assemblies are calibrated to measure the foot angle. Two spirit levels orient the device in space. Body element weights are placed at the corresponding centres of gravity to provide seat penetration equivalent to a 76 kg male. All joints of the 3-D H machine should be checked for free movement without encountering noticeable friction.

ANNEX 7

DYNAMIC TEST AS AN ALTERNATIVE TO THE SAFETY-BELT ANCHORAGES STATIC STRENGTH TEST

1.   SCOPE

This annex describes a dynamic sled test that can be performed as an alternative to the safety-belt anchorages static strength test prescribed in paragraphs 6.3 and 6.4 of this Regulation.

This alternative can apply at the request of the car manufacturer in the case of a group of seats where all the seating positions are equipped with 3-point safety-belts to which thorax load limiter functions are associated and when the group of seats additionally comprises a seating position for which the upper safety-belt anchorage is located on the seat structure.

2.   PRESCRIPTIONS

In the dynamic test prescribed in paragraph 3. of this annex, there shall be no rupture of any anchorage or surrounding area. A programmed rupture necessary for the functioning of the load limiter device is however permitted.

The minimum spacings for the effective lower anchorages specified in paragraph 5.4.2.5 of this Regulation, and the requirements for the effective upper anchorages specified in paragraph 5.4.3.6 of this Regulation and, when applicable, completed by the following paragraph 2.1.1, shall be respected.

2.1.1.   For vehicles of category M1 of a total permissible mass not exceeding 2,5 tonnes, the upper safety-belt anchorage, if attached to the seat structure, shall not be displaced forward of a transverse plane passing through the R point and point C of the seat in question (see figure 1 of Annex 3 to this Regulation).

For vehicles other than mentioned above, the upper safety-belt anchorage shall not be displaced forward of a transverse plane inclined 10° in forward direction and passing through the R point of the seat.

2.2.   In vehicles where such devices are used, the displacement and locking devices enabling the occupants of all seats to leave the vehicle must still be operable by hand after the test.

2.3.   The vehicle owner's manual shall include indications that each safety-belt shall only be replaced by an approved safety-belt for the considered seating position in the vehicle, and shall in particular identify those seating positions which may only be fitted with an appropriate safety-belt equipped with a load limiter.

3.   DYNAMIC TEST CONDITIONS

3.1.   General conditions

The general conditions described in paragraph 6.1 of this Regulation apply to the test described in this annex.

3.2.   Installation and preparation

3.2.1.   Sled

The sled must be so constructed that no permanent deformation appears after the test. It must be so guided that, during the impact phase, the deviation does not exceed 5° in the vertical plane and 2° in the horizontal plane.

3.2.2.   Securing of the vehicle structure

The part of the vehicle structure considered essential for the vehicle rigidity regarding the seat anchorages and the safety-belt anchorages shall be secured on the sled, according to the disposals described in paragraph 6.2 of this Regulation.

3.2.3.   Restraint systems

3.2.3.1.   The restraint systems (the complete seats, the safety-belt assemblies and the load limiter devices) shall be mounted on the vehicle structure according to the series production vehicle specifications.

The vehicle environment facing the tested seat (dashboard, seat, etc., depending on the tested seat) can be mounted on the test sled. If there were a frontal airbag, it has to be deactivated.

3.2.3.2.   At the request of the car manufacturer and in agreement with the technical service in charge of the tests, some components of the restraint systems other than the complete seats, the safety-belt assemblies and the load limiter devices, may not be mounted on the test sled or may be replaced by components having equivalent or lower stiffness and whose dimensions are comprised in the vehicle interior fittings dimensions, provided that the tested configuration is at least as unfavourable as the series configuration regarding the forces applying to the seat and safety-belt anchorages.

3.2.3.3.   The seats shall be adjusted as required in paragraph 6.1.2 of this Regulation, in the position for use chosen by the technical service in charge of the tests as the one giving the most adverse conditions regarding the anchorages strength and compatible with the installation of the dummies in the vehicle.

3.2.4.   Dummies

A dummy whose dimensions and mass are defined in Annex 8 shall be positioned on each seat and restrained by the safety-belt provided in the vehicle.

No dummy instrumentation is required.

3.3.   Test

3.3.1.   The sled shall be so propelled that, during the test, its speed variation is 50 km/h. The sled deceleration shall be within the corridor specified in Annex 8 of Regulation No 16.

3.3.2.   If applicable, the activation of additional restraining devices (preloading devices, etc., except airbags) is triggered according to the car manufacturer's indications.

3.3.3.   It shall be checked that the safety-belt anchorages' displacement does not exceed the limits specified in paragraphs 2.1 and 2.1.1 of this annex.
