5.7.2.1.3.                  where there is one contoured seating position the lateral distance from its centreline to the far end of the adjacent 'Seat' cushion, or to its side wall if this is less than 100 mm from the end of the cushion, is less than 1025 mm.
5.7.3.                              Effective Cushion Width - This is the width of the 'Seat' cushion measured horizontally at the intersection of the 'Seat' cushion with the transverse plane through the 'Torso Reference Line'.  It is determined by an analysis of 'Seat', 'Seat' back and vehicle structure sections on the transverse plane as follows:
5.7.3.1.                        if a cushion is separated from another cushion by less than 100 mm the 2 cushions shall be regarded as continuous;
5.7.3.2.                        if an end of the cushion is separated from adjoining structure by less than 100 mm it shall be regarded as extending to the adjoining structure;

         and

5.7.3.3.                        should the cushion widths determined by 5.7.3.1 and 5.7.3.2 exceed the internal width of the vehicle measured through a point located 562 mm from the 'Seating Reference Point' when measured along the 'Torso Reference Line', then the effective cushion width shall be the internal width of the vehicle determined at this height

5.9.                                    'AREA A' AND 'AREA B'
5.9.1.                              'Area A' - is dependent on the 'Seat Back Angle' and on its 'Transverse Distance S' from the 'Seating Reference Plane'. The 'Seat Back Angle' shall be as the design 'Seat Back Angle'.
5.9.1.1.                        For a particular value of S and subject to Clause 5.9.1.2, 'Area A' is located as follows: (refs Fig. 1)
5.9.1.1.1.                  above a horizontal transverse plane DJ located 450 mm above the 'Seating Reference Point' R;
5.9.1.1.2.                  to the rear of a transverse plane FK inclined downward at the rear 120o to the 'Torso Reference Line' and passing through a point B on the 'Torso Reference Line' and located 260 mm + S from the 'Seating Reference Point';
5.9.1.1.3.                  below a transverse plane FN inclined upward at the rear 65o to the 'Torso Reference Line' and passing through a pant C along the 'Torso Reference Line' located 315 mm + 1.6S from the 'Seating Reference Point' R: and
5.9.1.1.4.                  'Forward' of a vertical transverse plane NJ located 1.3S 'Rearward' of point M on 'Torso Reference Line'.
5.9.1.2.                        In cases when S is less than 200 mm, 'Area A' as defined in Clause 5.9.1.1 is extended by the addition of an area KPQT constructed as follows:
5.9.1.2.1.                  extend DJ to point P so that MP = 250 mm
5.9.1.2.2.                  draw line DQ so that angle PDQ is 20o and angle DPQ is 90o; and
5.9.1.2.3.                  extend FK to intersect DQ at point T.
5.9.2.                              'Area B'
