Driver's field of vision6.1.1. The dimensional relationships between the vehicle's primary reference marks and the three-dimensional reference grid shall be determined by the procedure prescribed in Annex IV.6.1.2. The position of the points V1 and V2 are determined in relation to the R point as indicated by XYZ coordinates from the three-dimensional reference grid and are shown in Table I under 5.2.1.1 and Table IV under 5.4. The windscreen datum points shall then be found from the corrected V points as prescribed in 5.1.1.6.1.3. The relationship between the P points, the R point, and the centre-line of the driver's seating position, as indicated by XYZ coordinates from the three-dimensional reference grid, shall be determined from Tables II and III in 5.3. The correction for design seat-back angles other than 25° is shown in Table IV under 5.4.6.1.4. The angle of binocular obstruction (see 5.1.2) shall be measured in the horizontal plane as indicated in Annex IV, Appendix, figure 2. The relationship between P1 and P2, which are connected to E1 and E2 and E3 and E4 respectively, is shown in Annex IV, Appendix, figure 4.6.1.4.1. The line E1 — E2 shall be set as described in 5.5.2. The angle of binocular obstruction is then measured between the tangent connecting E1 to the outer edge of the left A pillar and the tangent connecting E2 to the inner edge of the left A pillar.6.1.4.2. The line E3 — E4 shall be set as described in 5.5.4. The angle of binocular obstruction is then measured between the tangent connecting E4 to the outer edge of the right A pillar and the tangent connecting E3 to the inner edge of the right A pillar.[1] OJ No L 68, 22. 3. 1971, p. 1.--------------------------------------------------(ANNEX II)--------------------------------------------------ANNEX IIIPROCEDURE FOR DETERMINING THE H POINT AND THE ACTUAL SEAT-BACK ANGLE AND FOR VERIFYING THE RELATIVE POSITIONS OF THE R AND H POINTS AND THE RELATIONSHIP BETWEEN THE DESIGN SEAT-BACK ANGLE AND THE ACTUAL SEAT-BACK ANGLE1. DEFINITIONS1.1. H pointThe H point, which indicates the position of a seated occupant in the passenger compartment, is the intersection, in a longitudinal vertical plane, of the theoretical axis of rotation between the thighs and torso of a human body represented by the manikin described in section 3.1.2. R point or seating reference pointThe R point or seating reference point is the reference point specified by the vehicle manufacturer which1.2.1. has coordinates determined in relation to the vehicle structure;1.2.2. corresponds to the theoretical position of the point of torso/thighs rotation (H point) for the lowest and most rearward normal driving position or position of use given by the vehicle manufacturer for each seating position specified by him.1.3. Seat-back angleSeat-back angle means the inclination of the seat-back in relation to the vertical.1.4. Actual seat-back angleActual seat-back angle means the angle formed by the vertical through the H point with the torso reference line of the human body represented by the manikin described in section 3.1.5. Design seat-back angleDesign seat-back angle means the angle prescribed by the vehicle manufacturer which1.5.1. determines the seat-back angle for the lowest and most rearward normal driving position or position of use given by the vehicle manufacturer for each seating position specified by him;1.5.2. is formed at the R point by the vertical and the torso reference line; and1.5.3. corresponds theoretically to the actual seat-back angle.2. DETERMINATION OF H POINTS AND ACTUAL SEAT-BACK ANGLES2.1. An H point and an actual seat-back angle shall be determined for each seating position specified by the vehicle manufacturer. If the seating positions in the same row can be regarded as similar (bench seat, identical seats, etc.), only one H point and one actual seat-back angle shall be determined for each row of seats, the manikin described in section 3 being seated in a place regarded as representative for the row. This place shall be:2.1.1. in the case of the front row, the driver's seat;2.1.2. in the case of the rear row or rows, an outer seat;2.2. When an H point and an actual seat-back angle are being determined, the seat considered shall be placed in the lowest and most rearward normal driving position or position of use given for it by the vehicle manufacturer. The seat-back shall, if its inclination is adjustable, be locked as specified by the manufacturer, or in the absence of any such specification, in a position corresponding to an actual seat-back angle of as near as possible to 25°.3. DESCRIPTION OF THE MANIKIN3.1. A three-dimensional manikin of a mass and contour corresponding to those of an adult male of average height shall be used. Such a manikin is depicted in figures 1 and 2 of the Appendix to this Annex.3.2. The manikin shall comprise:3.2.1. two components, one simulating the back and the other the seat of the body, pivoting on an axis representing the axis of rotation between the torso and the thigh. The intersection of this axis with the vertical medium longitudinal plane of the seating position determines the H point;3.2.2. two components simulating the legs and pivotally attached to the component simulating the seat; and3.2.3. two components simulating the feet and connected to the legs by pivotal joints simulating ankles.3.2.4. In addition, the component simulating the seat of the body shall be provided with a level enabling its transverse orientation to be verified.3.3. Body-segment weights shall be attached at appropriate points corrresponding to the relevant centres of gravity, so as to bring the total mass of the manikin up to 75 kg ± 1 %. Details of the mass of the various weights are given in the table in figure 2 of the Appendix to this Annex.3.4. The torso reference line of the manikin is represented by a straight line passing through the joint between the thigh and the torso and the theoretical joint between the neck and the thorax (see the Appendix to this Annex, figure 1).4. SETTING UP THE MANIKINThe three-dimensional manikin shall be set up in the following manner:4.1. the vehicle shall be placed on a horizontal plane and the seats adjusted as prescribed in 2.2;4.2. the seat to be tested shall be covered with a piece of cloth to facilitate the correct setting-up of the manikin;4.3. the manikin shall be placed on the seat concerned, its pivotal axis being perpendicular to the median longitudinal plane of the vehicle;4.4. the feet of the manikin shall be placed as follows;4.4.1. in the front seats, in such a way that the level verifying the transverse orientation of the seat of the manikin is brought to the horizontal;4.4.2. in the rear seats, as far as possible in such a way as to be in contact with the front seats. If the feet then rest on parts of the floor which are at different levels, the foot which first comes into contact with the front seat shall serve as a reference point and the other foot shall be so arranged that the level enabling the transverse orientation of the seat of the manikin to be verified is brought to the horizontal;4.4.3. if the H point is being determined at a centre seat, the feet shall be placed one on each side of the tunnel;4.5. the weights shall be placed on the legs, the level verifying the transverse orientation of the seat of the manikin shall be brought to the horizontal, and the thigh weights shall be placed on the component representing the seat of the manikin;4.6. the manikin shall be moved away from the seat-back by means of the knee-pivot bar and the back of the manikin shall be pivoted forwards. The manikin shall be repositioned on the seat of the vehicle by being slid backwards on its seat until resistance is encountered, the back of the manikin then being replaced against the seat-back;4.7. a horizontal load of 10 ± 1 daN shall be applied to the manikin twice. The direction and point of application of the load are shown by a black arrow in figure 2 of the Appendix;4.8. the seat weights shall be installed on the right and left sides, and the torso weights shall then be placed in position. The transverse level of the manikin shall be kept horizontal;4.9. the transverse level of the manikin being kept horizontal, the back of the manikin shall be pivoted forwards until the torso weights are above the H point, so as to eliminate any friction with the seat-back;4.10. the back of the manikin shall be gently moved rearwards so as to complete the setting-up operation. The transverse level of the manikin shall be horizontal. If it is not, the procedure described above shall be repeated.5. RESULTS5.1. When the manikin has been set up as described in section 4, the H point and the actual seat-back angle of the vehicle seat considered are constituted by the H point and the angle of inclination of the manikin's torso reference line.5.2. The coordinates of the H point in relation to three mutually perpendicular planes, and the actual seat-back angle, shall be measured for comparison with the data supplied by the vehicle manufacturer.6. VERIFYING THE RELATIVE POSITIONS OF THE R AND H POINTS AND THE RELATIONSHIP BETWEEN THE DESIGN SEAT-BACK ANGLE AND THE ACTUAL SEAT-BACK ANGLE6.1. The results of the measurements carried out in accordance with 5.2 for the H point and the actual seat-back angle shall be compared with the coordinates of the R point and the design seat-back angle as given by the vehicle manufacturer.6.2. The relative positions of the R point and the H point and the relationship between the design seat-back angle and the actual seat-back angle shall be considered to be satisfactory for the seating position in question if the H point, as defined by its coordinates, lies within a longitudinal rectangle whose horizontal and vertical sides are 30 mm and 20 mm long respectively and whose diagonals intersect at the R point, and if the actual seat-back angle is within 3° of the design seat-back angle.6.2.1. If these conditions are met, the R point and the design seat-back angle shall be used for the test and, if necessary, the manikin shall be so adjusted that the H point coincides with the R point and the actual seat-back angle coincides with the design seat-back angle.6.3. If the H point or the actual seat-back angle does not satisfy the requirements of 6.2, the H point or the actual seat-back angle shall be determined twice more (three times in all). If the results of two of these three operations satisfy the requirements, the results of the test shall be considered to be satisfactory.6.4. If at least two of the three test results do not satisfy the requirements of 6.2, the result of the test shall be considered to be not satisfactory.6.5. If the situation described in 6.4 arises, or if verification is not possible because the vehicle manufacturer has failed to supply information regarding the position of the R point or regarding the design seat-back angle, the average of the results of the three tests may be used and be regarded as applicable in all cases where the R point or the design seat-back angle is referred to in this Directive.6.6. For verifying the relative positions of the R point and the H point and the relationship between the design seat-back angle and the actual seat-back angle in a series-produced vehicle, the rectangle referred to in 6.2 shall be replaced by a square of 50 mm side and the actual seat-back angle shall not differ by more than 5° from the design seat-back angle.--------------------------------------------------AppendixCOMPONENTS OF THREE-DIMENSIONAL MANIKIN+++++ TIFF +++++DIMENSIONS AND MASS OF MANIKINMass of manikin | kg |Components simulating back and seat of body | 16 |Mass of torso weights | 31 |Mass of seat weights | 8 |Mass of thigh weights | 7 |Mass of leg weights | 13 |Total: | 75 |+++++ TIFF +++++Figure 2--------------------------------------------------ANNEX IVMETHOD FOR DETERMINING THE DIMENSIONAL RELATIONSHIPS BETWEEN THE VEHICLE'S PRIMARY REFERENCE MARKS AND THE THREE-DIMENSIONAL REFERENCE GRID1. RELATIONSHIP BETWEEN REFERENCE GRID AND VEHICLE PRIMARY REFERENCE MARKSTo verify specific dimensions on or within a vehicle submitted for type-approval in accordance with this Directive, the relationship between the coordinates of the three-dimensional reference grid, defined in 2.3 of Annex I, which has been laid out at the initial vehicle-design stage, and the positions of the primary reference marks defined in 2.4 of Annex I, must be established accurately so that specific points on the vehicle manufacturer's drawings can be identified on an actual vehicle produced from those drawings.2. METHOD FOR ESTABLISHING RELATIONSHIP OF REFERENCE GRID TO REFERENCE MARKSFor this purpose, a ground reference plane shall be constructed which is marked with the X-X measurement and the Y-Y measurement. The method of achieving this is set out in figure 6 of the Appendix to this Annex, the reference plane being a hard, flat, level surface upon which the vehicle stands, and which has two measuring scales firmly fixed to its surface; these shall be graduated in millimetres, the X-X scale being not less than eight metres long, and the Y-Y scale not less than four metres long. The two scales must be set at right angles to each other as shown in figure 6 of the Appendix to this Annex. The intersection of these scales is ground zero.3. EXAMINATION OF THE REFERENCE PLANEIn order to provide for minor variations in the level of the reference plane or test area, it will be necessary to measure the deviations from ground zero along both the X and Y scales at intervals of 250 mm and to record the readings obtained so that corrections can be made when checking the vehicle.4. ACTUAL TEST ATTITUDEIn order to provide for minor changes in suspension height, etc., it will be necessary to have available a means of bringing the primary reference marks to the correct coordinate positions relative to the design attitude before further measurements are taken. In addition, it must be possible to make minor lateral and/or longitudinal adjustments of the vehicle's position so as to place it accurately in relation to the reference grid.5. RESULTSThe vehicle having been correctly placed relative to the reference grid and in its design attitude, the site of the necessary points for studying the forward visibility requirements can be readily determined.Test methods to determine these requirements may include the use of theodolites, light sources or shadow devices, or any other method which can be shown to give equivalent results.+++++ TIFF +++++DETERMINATION OF V POINTS+++++ TIFF +++++PILLAR OBSTRUCTIONDiagram showing layout of P points and E points, for viewing the left-hand and right-hand pillars(special case provided for in section 5.5.2.2 of Annex I)+++++ TIFF +++++EVALUATION OF OBSTRUCTIONS IN THE 180° FORWARD DIRECT FIELD OF VISION OF THE DRIVER+++++ TIFF +++++DIMENSIONAL DIAGRAM SHOWING RELATIVE POSITIONS OF E POINTS AND P POINTS+++++ TIFF +++++THREE-DIMENSIONAL REFERENCE GRID+++++ TIFF +++++LEVEL WORK SPACE--------------------------------------------------ANNEX VMODEL+++++ TIFF +++++--------------------------------------------------
