Australia, 46 for Ukraine, 47 for South Africa and 48 for New Zealand. Subsequent numbers shall be assigned to other countries in the chronological order in which they ratify or accede to the Agreement Concerning the Adoption of Uniform Technical Prescriptions for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or be Used on Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of these Prescriptions, and the numbers thus assigned shall be communicated by the Secretary-General of the United Nations to the Contracting Parties to the Agreement.

5.                                     SPECIFICATIONS

5.1.                               Definitions (see annex 3)

5.1.1.                         The H point is a reference point as defined in paragraph 2.3. of annex 4 of this Regulation, which must be determined in accordance with the procedure set out in that annex.

5.1.1.1.                   Point H' is a reference point corresponding to H as defined in paragraph 5.1.1. which shall be determined for every normal position in which the seat is used.

5.1.1.2.                   The R point is the seating reference point defined in paragraph 2.4. of annex 4 of this Regulation.

5.1.2.                         The three-dimensional reference system is defined in appendix 2 of annex 4 of this Regulation.

         5.1.3.                         Points L1 and L2 are the lower effective belt anchorages.

5.1.4.                         Point C is a point situated 450 mm vertically above the R point. However, if the distance S as defined in paragraph 5.1.6. is not less than 280 mm and if the alternative formula BR = 260 mm + 0.8 S specified in paragraph 5.4.3.3. is chosen by the manufacturer, the vertical distance between C and R shall be 500 mm.

5.1.5.                         The angles α1 and α2 are respectively the angles between a horizontal plane and planes perpendicular to the median longitudinal plane of the vehicle and passing through the point H1 and the points L1 and L2.

5.1.6.                         S is the distance in millimetres of the effective upper belt anchorages from a reference plane P parallel to the longitudinal median plane of the vehicle defined as follows:

5.1.6.1.                   if the seating position is well-defined by the shape of the seat, the plane P shall be the median plane of this seat.

5.1.6.2.                   in the absence of a well-defined position:

5.1.6.2.1.            the plane P for the driver's seat is a vertical plane parallel to the median longitudinal plane of the vehicle which passes through the centre of the steering-wheel in the plane of the steering-wheel rim when the steering-wheel, if adjustable, is in its central position.

5.1.6.2.2.            the plane P for the front outboard passenger shall be symmetrical with that of the driver.

5.1.6.2.3.            The plane P for the rear outboard seating position shall be that specified by the manufacturer
