to both the front and rear seats and the upper anchorage is fitted to the "B" post, the system must be designed so as not to impede access to or egress from the vehicle.

5.4.3.2.                   The effective upper anchorage shall lie below the plane FN, which runs perpendicular to the longitudinal median plane of the seat and makes an angle of 65° with the torso line. The angle may be reduced to 60° in the case of rear seats. The plane FN shall be so placed as to intersect the torso line at a point D such that DR = 315 mm + 1.8 S. However, when S ≤ 200 mm, then DR = 675 mm.

5.4.3.3.                   The  effective  upper  belt  anchorage  shall  lie  behind  a  plane  FK  running perpendicular to the longitudinal median plane of the seat and intersecting the torso line at an angle of 120° at a point B such that BR = 260 mm + S.

Where S ≥ 280 mm, the manufacturer may use BR = 260 mm + 0.8 S at his discretion.

         5.4.3.4.                   The value of S shall not be less than 140 mm.

5.4.3.5.                   The effective upper belt anchorage shall be situated to the rear of a vertical plane perpendicular to the median longitudinal plane of the vehicle and passing through the R point as shown in annex 3.

5.4.3.6.                   The effective upper belt anchorage shall be situated above a horizontal plane passing through point C defined in paragraph 5.1.4.

5.4.3.7.                   In addition to the upper anchorage specified in paragraph 5.4.3.1. other effective upper anchorages may be provided if one of the following conditions is satisfied:

5.4.3.7.1.            The additional anchorages comply with the requirements of paragraphs 5.4.3.1. to 5.4.3.6.

5.4.3.7.2.            The additional anchorages can be used without the aid of tools, comply with the requirements of paragraphs 5.4.3.5. and 5.4.3.6. and are located in one of the areas determined by shifting the area shown in figure 1 of annex 3 of this Regulation, 80 mm upwards or downwards in a vertical direction.

5.4.3.7.3.            The anchorage(s) is/are intended for a harness belt, complies/comply with the requirements laid down in paragraph 5.4.3.6. if it lie(s) behind the transverse plane passing through the reference line and is/are located:

5.4.3.7.3.1.      In the case of a single anchorage, within the area common to two dihedrals defined by the verticals passing through points J1 and J2 as defined in paragraph 5.4.3.1. and whose horizontal sections are shown in figure 2 of annex 3 of this Regulation;
5.4.3.7.3.2.      In the case of two anchorages, within whichever of the above defined dihedrals is suitable, provided that each anchorage is not more than 50 mm distant from the
symmetrically-located, mirror-image position
