are exposed so as to be contactable by a sphere of 70 mm diameter.
66.2.4.                          Armrests
         Armrests must be tested in the directions shown in Figure 1, using the forces specified below, applied using a semi-cylindrical form of 50 mm radius and a length of 200 mm. Each location must be loaded separately.
66.2.4.1.                    A vertical load (i) of 1,000 N shall be applied to the armrest at locations within 30 mm of each end and at the centre of the armrest, with the loading form horizontal and transversely across the armrest.
66.2.4.2.                    A horizontal longitudinal load (ii) of 2,000 N shall be applied to the rear upper 30 mm of each armrest, with the the loading form vertical.
66.2.4.3.                    A horizontal load (iii) of 1,000 N shall be applied to locations within 30 mm of the ends of the armrest, with the the loading form vertical.  These loads shall be applied in both directions to the 'Forward' end of the armrest and towards the 'Seat' at the rear end of the armrest, and outwards from the 'Seat' at the rear end of the armrest if that part of the armrest is exposed in any position of the 'Seat'.
66.2.4.4.                    After the specified loads have been applied, no projections or edges may be exposed as a consequence of the application of these loads so as to be contactable by a sphere of 70 mm diameter.
66.2.4.5.                    All radii contactable by a sphere 165 mm in diameter must present a radius of curvature of at least 5 mm.
66.2.4.6.                    If any part of the fittings and accessories is made of a material of hardness less than 50 shore A on a rigid backing, the requirements set out in clause 6 apply only to the rigid backing.
66.2.5.                          The occupant of every 'Seat' without another 'Seat' meeting this rule immediately in front of it shall be protected by means equivalent to the protection given in paragraph 5.2 of Appendix A.
66.2.5.1.                    This protection may be provided by either a seat belt or a padded structure providing protection at least equivalent to that provided by a 'Seat' back complying with this rule.  If a seat belt is used then the strength of the 'Seat' shall be such that it is capable of withstanding the seat belt load and the load required by paragraph 5.2 of Appendix A simultaneously.

         If a 'Lap-Sash Belt' is used no limitations are placed upon the presence or construction of such items as modesty panels in front of the 'Seat'.

         If a 'Lap Belt' is used there shall be no obstructions between the 'Seat' and a vertical plane 1,300 mm 'Forward' of the 'Seating Reference Point'.
