COUNCIL DIRECTIVE

of 22 July 1974

relating to motor vehicles with regard to the seats, their anchorages and head restraints

(74/408/EEC)

▼B







THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 100 thereof; Having regard to the proposal from the Commission; Having regard to the Opinion of the European Parliament ( 1 ); Having regard to the Opinion of the Economic and Social Committee; Whereas the technical requirements which motor vehicles must satisfy pursuant to national laws relate, inter alia, to interior fittings for the strength of seats and their anchorages; Whereas these requirements differ from one Member State to another; whereas it is therefore necessary that all Member States adopt the same requirements either in addition to or in place of their existing regulations in order, in particular, to allow of the EEC type-approval procedure, which was the subject of Council Directive No 70/156/EEC ( 2 ) of 6 February 1970 on the approximation of laws of the Member States relating to the type-approval of motor vehicles and their trailers, to be applied in respect of each type of vehicle; Whereas common requirements for the interior fittings of the passenger compartment, the layout of the controls, the roof, the backrests and the rear part of the seats have been laid down by Council Directive No 74/60/EEC ( 3 ) of 17 December 1973; whereas requirements for the internal fittings for the behaviour of the steering mechanism in the event of an impact have been laid down by Council Directive 74/297/EEC ( 4 ) of 4 June 1974; whereas other requirements for the internal fittings, and in particular those relating to the head restraint, the seat belt anchorages and the layout of the controls, will be adopted at a later date; Whereas it is appropriate to utilize basically certain technical requirements adopted by the UN Economic Commission for Europe in its Regulation No 17 ( 5 ) (Uniform provisions concerning the approval of vehicles with regard to the strength of the seats and of their anchorages) which is annexed to the Agreement of 20 March 1958 concerning the adoption of uniform conditions of approval and reciprocal recognition of approval for motor vehicle equipment and parts; Whereas the approximation of national laws relating to motor vehicles entails mutual recognition by Member States of inspection carried out by each of them on the basis of common provisions; whereas such a system must, if it is to function smoothly, be applied by all Member States with effect from the same date, HAS ADOPTED THIS DIRECTIVE:

After the tests, the displacement systems intended for permitting or facilitating the access of occupants must be in working order; they must be capable, at least once, of being unlocked and must permit the displacement of the seat or the part of the seat for which they are intended. 3.2.8. Any other displacement systems, as well as adjustment systems and their locking systems are not required to be in working order. 3.2.9. In the case of seats provided with head restraints, the strength of the seat back and of its locking devices is deemed to meet the requirements set out in Paragraph 2 when, after testing in accordance with Paragraph 4.3.6, no breakage of the seat or seat back has occurred; otherwise, it must be shown that the seat is capable of meeting the requirements set out in Paragraph 2. 3.2.10. In the case of seats (benches) with more places to sit than head restraints, the test described in Paragraph 2 shall be carried out.

3.3. Special requirements for seats fitted or capable of being fitted with head restraints. 3.3.1. The presence of the head restraint must not be an additional cause of danger to the 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. 3.3.2. Parts of the front and rear faces of the head restraints situated in Area 1, as defined in Paragraph 8.1.1.3 of Appendix 1, shall pass the energy absorption test. 3.3.2.1. This requirement is deemed to be met if in the tests carried out by the procedure specified in Appendix 2 the deceleration of the headform does not exceed 80g continuously for more than 3 ms. Moreover, no dangerous edge shall occur during or remain after the test. 3.3.3. Parts of the front and rear faces of head restraints situated in Area 2, as defined in Paragraph 8.1.2 of Appendix 1, 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 3.2.4 applicable to the rear parts of seats situated in Area 2. 3.3.4. The requirements of Paragraphs 3.3.2 and 3.3.3 shall not apply to parts of rear faces of head restraints designed to be fitted to seats behind which no seat is provided. 3.3.5. 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 head form during the test. 3.3.6. In the case of a seat fitted with a head restraint, the provisions of Paragraph 3.2.3 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 3.3.2.

3.4. Height of head restraints 3.4.1. The height of head restraints shall be measured as described in Paragraph 5 of Appendix 1. 3.4.2. For head restraints not adjustable for height, the height shall be not less than 800 mm ( 19 ) for front seats and not less than 750 mm ( 20 ) for other seating positions. 3.4.3. For head restraints adjustable for height: 3.4.3.1. the height shall be not less than 800 mm (20) for front seats and not less than 750 mm (20) for other seating positions; this value shall be obtained in a position between the highest and lowest positions to which adjustment is possible; 3.4.3.2. there shall be no use position resulting in a height of less than 750 mm (20) ; 3.4.3.3. 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 (20) , provided that such position is clearly recognisable to the occupant as not being intended for the use of the head restraint; 3.4.3.4. 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 (20) , provided that they automatically return to the position of use when the seat is occupied. 3.4.4. The dimensions mentioned in paragraphs 3.4.2 and 3.4.3.1 above may be reduced 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 way of derogation from paragraph 3.4.3.2, there shall not be any use position resulting in a height lower than 700 mm. 3.4.5. By derogation to the height requirements mentioned in Paragraphs 3.4.2, 3.4.3.1 and 3.4.3.2, the height of any head restraint designed to be provided in rear centre seats or seating positions shall be not less than 700 mm.

3.5. In the case of a seat capable of being fitted with a head restraint, the provisions of Paragraphs 3.2.3 and 3.3.2 shall be verified. 3.5.1. The height of the part of the device on which the head rests, measured as described in Paragraph 5 of Appendix 1, shall in the case of a head restraint adjustable for height be not less than 100 mm.

3.6. 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.

3.7. 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 7 of Appendix 1, are permitted, provided that, after the additional test under Paragraph 4.3.3.2 of Appendix 1, the requirements of Paragraph 3.10 are still met.

3.8. 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 7 of Appendix 1, are permitted on the part of the device serving as a head restraint provided that, after the additional test under Paragraph 4.3.3.2 of Appendix 1, the requirements of Paragraph 3.10 are still met.

3.9. 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 of Appendix 1, 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.

3.10. 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 4.3 of Appendix 1, is less than 102 mm.

3.12. 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.

3.13. The strength of the seat back and of its locking devices is deemed to meet the requirements set out in Paragraph 2 of Appendix 1 when, after testing in accordance with Paragraph 4.3.6 of Appendix 1 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 2 of Appendix 1.









Appendix 1

Tests and instructions for use

1. General specifications applicable to all tests

1.1. The seat back, if adjustable, shall be locked in a position corresponding to a rearward inclination as close as possible to 25o from the vertical of the torso reference line of the manikin shown in Figure 1, unless otherwise specified by the manufacturer.

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.

1.3. ►C1 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. ◄

2. Test of strength of the seat back and its adjustment systems

2.1. A force producing a moment of 530 Nm in relation to the R point shall be applied longitudinally and rearwards to the upper part of the seat back frame through a component stimulating the back of the manikin. 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.

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

3.1. ►C1 A longitudinal horizontal deceleration of not less than 20g shall be applied for 30 ms in the forward direction to the whole shell, or a representative part of the shell, of the vehicle, in accordance with the requirements of Paragraph 1 of Appendix 3. ◄

3.2. A longitudinal deceleration in accordance with the requirements of Paragraph 3.1 shall be applied in the rearward direction.

3.3. The requirements of Pargraphs 3.1 and 3.2 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 3.4.

3.4. In cases where the arrangement of the locking systems is such that, in a seat position other than those defined in Paragraph 3.3, the distribution of the forces on the locking devices and seat anchorages would be less favourable than with either configuration defined in Paragraph 3.3, the tests shall be conducted for that less favourable seating position.

3.5. The test conditions of paragraph 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 Appendix 3 to this Annex. 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 paragaphs 1.1, 3.3 and 3.4.

4. Test of the performance of the head restraint

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.

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.

4.3. Test 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 Figure 2). 4.3.2. The displaced reference line is determined by applying to the part simulating the back of the manikin referred to in Figure 2 an initial force producing a rearward moment of 373 Nm about the R point. 4.3.3. By means of a spherical headform 165 mm in diameter an initial force producing a moment of 373 Nm 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 as determined in accordance with the requirements of Paragraph 4.3.2. 4.3.3.1. If the presence of gaps prevents the application of the force prescribed in Paragraph 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. 4.3.3.2. In the case described in paragraphs 3.7 and 3.8 of Annex II, 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 373 Nm about the R point. 4.3.4. The tangent Y to the spherical headform, parallel to the displaced reference line, is determined. 4.3.5. The distance X provided for in Paragraph 3.10 of Annex II, between the tangent Y and the displaced reference line is measured. 4.3.6. To check the effectiveness of the head restraint, the initial load specified in Paragraphs 4.3.3 and 4.3.3.2 is increased to 890 N unless the breakage of the seat or seat back occurs earlier.

5. Determination of the height of the head restraint

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 1a).

5.2. The manikin described in Annex III to Directive 77/649/EEC shall be placed in a normal position on the seat.

5.3. The projection of the reference line of the manikin is then, in the seat concerned, drawn in the plane specified in Paragraph 4.3.1. The tangent S to the top of the head restraint is drawn perpendicular to the reference line.

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 3.4 of Annex II.

6. Determination of the width of the head restraint (see Figure 1b)

6.1. The plane S1, perpendicular to the reference line and situated 65 mm below the tangent S defined in Paragraph 5.3, determines a section in the head restraint bounded by the outline C.

6.2. The width of the head restraint to be taken into consideration in implementing the requirements of Paragraph 3.9 of Annex II is the distance ‘L’ measured in the plan S1 between the vertical longitudinal planes p and p′.

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.

7. Determination of distance ‘a’ of head restraint gaps (see Figure 3)

7.1. The distance ‘a’ shall be determined for each gap and in relation to the front face of head restraint, by means of a sphere having a diameter of 165 mm.

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.

7.3. ►C1 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 3.7 and 3.8 of Annex II. ◄

8. Tests for checking energy dissipation on the seat back and head restraint

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. 8.1.1. Area 1 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 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. 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. 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. 8.1.2. Area 2 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. 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. 8.1.3. Area 3 8.1.3.1.
