10.3.1.3.                    should the cushion widths determined by 10.3.1.1 and 10.3.1.2 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 must be the internal width of the vehicle determined at this height.
11.                                      AREA A AND AREA B
11.1.                                'Area A'
11.1.1.                          'Area A' is dependent on the 'Seat Back Angle' and on its 'Transverse Distance S' from the 'Seating Reference Plane'. The 'Seat Back Angle' must be taken as the design 'Seat Back Angle'.
11.1.2.                          For a particular value of S and subject to clause 11.1.3, 'Area A' is located as follows (refer Fig. 1):
11.1.2.1.                    above a horizontal transverse plane DJ located 450 mm above the 'Seating Reference Point' R;
11.1.2.2.                    to the rear of a transverse plane FK inclined downward at the rear 120° 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';
11.1.2.3.                    below a transverse plane FN inclined upward at the rear 65° to the 'Torso Reference Line' and passing through a point C along the 'Torso Reference Line' located 315 mm + 1.6 S from the 'Seating Reference Point' R; and
11.1.2.4.                    'Forward' of a vertical transverse plane NJ located 1.3 S 'Rearward' of point M on the 'Torso Reference Line'.
11.1.3.                          In cases where S is less than 200 mm, 'Area A' as defined in clause 11.1.2 is extended by the addition of an area KPQT constructed as follows:
11.1.3.1.                    extend DJ to point P so that MP = 250 mm
11.1.3.2.                    draw line DQ so that angle PDQ is 20° and angle DPQ is 90°; and
11.1.3.3.                    extend FK to intersect DQ at point T.
11.2.                                'Area B'
11.2.1.                          Transverse Location - 'Area B' extends transversely from a plane 140 mm from and parallel to the 'Seating Reference Plane' and on the same side as the 'Sash Guide'.
11.2.2.                          Longitudinal Location - In side elevation relative to the 'Seating Reference Plane', 'Area B' is established as follows:
11.2.2.1.                    to the rear of a transverse vertical plane CD located 100 mm 'Rearward' of the 'Seating Reference Point' R;
11.2.2.2.                    above a horizontal plane CE located 400 mm above the 'Seating Reference Point' R; and
11.2.2.3.                    below a horizontal DF located 710 mm above the 'Seating Reference Point' R.
11.2.3.                          Notwithstanding the requirements of clauses 11.2.2.1, 11.2.2.2 and 11.2.2.3 above the location in side elevation may be as follows:
11.2.3.1.                    to the rear of a point G located 555 mm above and 120 mm 'Rearward' of the 'Seating Reference Point'
