ANNEX I U.K. SCOPE, DEFINITIONS, APPLICATION FOR EEC COMPONENT TYPE-APPROVAL, GENERAL SPECIFICATIONS, TESTS AND CONFORMITY OF PRODUCTION

1. SCOPE U.K.

1.1. This Directive applies to head restraints (head rests): U.K.

• forming an integral part of the seatback, or

• designed to be installed on the seat,

of motor vehicles conforming to the definition given in Article 9 and intended for separate use, i.e. as individual equipment by adult occupants of forward-facing seats.

2. DEFINITIONS U.K.

2.1. Vehicle type with regard to head restraints U.K.

‘Vehicle type with regard to head restraints’ means vehicles which do not differ in such essential respects as:

2.1.1. the lines and internal dimensions of the bodywork constituting the passenger compartment; and U.K.

2.1.2. the types and dimensions of the seats. U.K.

2.2. Head restraint U.K.

‘Head restraint’ means a device whose purpose is to limit the rearward displacement of the occupant's head in relation to his torso in order to reduce the danger of injury to the cervical vertebrae in the event of an accident. This device may or may not form an integral part of the seatback.

2.3. Type of seat U.K.

‘Type of seat’ means seats which do not differ in their dimensions, in their framework or in their padding, although they may differ in finish or colour.

2.4. Type of head restraint U.K.

‘Type of head restraint’ means head restraints which do not differ in their dimensions, in their framework or in their padding, although they may differ in finish, colour or covering.

2.5. H point U.K.

(see Annex II).

2.6. R point or seating reference point U.K.

(see Annex II).

2.7. Reference line r U.K.

‘Reference line r’ means a straight line which, either on a test manikin having the mass and dimensions of an average adult male or on a test manikin having identical characteristics, passes through the joint of the leg with the pelvis and the joint of the neck with the thorax. On the manikin referred to in Section 3 of Annex III to Council Directive 77/649/EEC of 27 September 1977 on the approximation of the laws of the Member States relating to the field of vision of motor vehicle drivers(1), to which reference is made in Annex II to this Directive, the reference line is that shown in Figure 1 in the Appendix to Annex III to Directive 77/649/EEC.

2.8. Head line U.K.

‘Head line’ means a straight line passing through the centre of gravity of the head and through the joint of the neck with the thorax. When the head is at rest the head line is situated in the extension of the reference line.

6.1. The presence of the head restraint in a vehicle must not be an additional cause of danger to occupants of the vehicle. In particular it must 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. Parts of the head restraint which are situated in the impact zone defined below must be capable of dissipating energy in the manner specified in Annex V to this Directive: U.K.

6.1.1. the impact zone must be bounded laterally by two vertical longitudinal planes, one on each side of and each 70 mm distant from the plane of symmetry of the seat concerned; U.K.

6.1.2. the impact zone must be limited in height to the part of the head restraint situated above the plane perpendicular to the reference line r and 635 mm distant from the R point. U.K.

6.2. Parts of the front and rear faces of the head restraint which are situated outward of the said vertical longitudinal planes must be so padded as to prevent any direct contact of the head with the structural components, which should in those areas have a radius of curvature of not less than 5 mm. U.K.

6.3. The head restraint must be anchored to the seat in such a way that no rigid and dangerous part projects from the padding of the head restraint, from the anchorage or from the seatback as a result of the pressure exerted by the head during the test. U.K.

6.4. The height of the head restraint, measured as described in 7.2, must not be less than 700 mm above the seating reference point R. U.K.

6.5. The height of the device on which the head rests, measured as described in 7.2, must, in the case of a head restraint adjustable for height, not be less than 100 mm. U.K.

6.6. There must be no gap of more than 50 mm between the seatback and the head restraint in the case of a device not adjustable for height. If the head restraint is adjustable for height, it must, when in the low position, be no more than 25 mm from the top of the seatback. U.K.

6.7. The width of the head restraint must be such as to provide suitable support for the head of a person normally seated. In the plane of measurement of width defined in 7.3, the head restraint shall cover an area extending not less than 85 mm to each side of the plane of symmetry of the seat for which the head restraint is intended, that distance being measured in accordance with 7.3. U.K.

7.2.2. The manikin corresponding to an average adult male or the manikin referred to in Section 3 of Annex III to Directive 77/649/EEC must be placed in a normal position on the seat. The seatback, if inclinable, is locked in a position corresponding to a rearward inclination of the reference line of the manikin's torso of as nearly as possible 25° from the vertical. U.K.

7.2.3. The projection of the reference line of the manikin referred to in Section 3 of Annex III to Directive 77/649/EEC is then, in the case of the seat concerned, drawn in the plane specified in 7.2.1. The tangent S to the top of the head restraint is drawn perpendicular to the reference line. U.K.

7.3.1. The plane S₁ perpendicular to the reference line and situated 65 mm below the tangent S defined in 7.2.3 defines a section in the head restraint bounded by the outline C. The direction of the straight lines tangential to C representing the intersection of the plane S₁ and the vertical planes (P and P′), parallel to the plane of symmetry of the seat concerned, are drawn in the plane S₁. U.K.

7.4.3. Testing U.K.

7.4.3.1. All lines must be drawn in the vertical plane of symmetry of the seat concerned (see Annex IV). U.K.

7.4.3.2. A projection of the reference line r is drawn in the plane referred to in 7.4.3.1. U.K.

7.4.3.3. The displaced reference line r₁ is determined by applying to the part simulating the back in the manikin referred to in Annex III to Directive 77/649/EEC, an initial force producing a rearward moment of 37·3 mdaN about the R point. U.K.

7.4.3.4. By means of a spherical head 165 mm in diameter an initial force producing a moment of 37·3 mdaN about the R point is applied at right angles to the displaced reference line r₁ at a distance of 65 mm below the top of the head restraint. U.K.

7.4.3.5. The tangent Y to the spherical head, parallel to the displaced reference line r₁, is determined. U.K.

7.4.3.6. The distance X between the tangent Y and the displaced reference line r₁ is measured. The requirement of 6.8 is deemed to be met if the distance X is less than 102 mm. U.K.

7.4.3.7. The initial load specified in 7.4.3.4 is increased to 89 daN unless breakage of the seat or the seatback occurs earlier. U.K.
