of application of each force prescribed in Appendix 1 measured in the horizontal plane and in the longitudinal median plane of the relevant seating position must not exceed 150 mm; and

             2.                         the headform deceleration determined by tests conducted in accordance with Appendix 2 must not exceed 785 m/s2 continuously for more than 3 milliseconds.

         4.                               Where the horizontal plane on which a 'Seat' is installed differs in height by more than 200 mm from that of the 'Seat' immediately in front of it, the tests required in clause 7 or Appendix 2 must be conducted with 'Seats' arranged to give that difference in height.

     3.                                     Seat-Anchorage Strength

         1.                               The seat-anchorages for every 'Seat' installed in the vehicle must withstand the forces which result from the tests specified in clauses 7 or Appendix 1.

         2.                               The seat-anchorage strength can be tested as specified in clause 8, by applying a force simulating that measured during a test as specified in clause 7 or Appendix 1 on that 'Seat Type' as specified in clause 7 or Appendix 1.

         3.                               One test conducted as specified in clause 7 or Appendix 1 may be used to determine simultaneously the adequacy of the seat anchorage strength of a 'Seat Type' and of a vehicle.

     4.                                     Seatbelt Assemblies

         1.                               Each 'Seat' must be equipped with a 'Seatbelt Assembly'.

         2.                               The 'Seatbelt Assembly' of front-facing 'Seats' must be a 'Lap-Sash Belt' equipped with an 'Emergency Locking Retractor' as specified in ADR 4/....

         3.                               The 'Seatbelt Assembly' of a rear-facing 'Seat' must be:

             1.                         a 'Lap Belt' equipped with an 'Emergency Locking Retractor' as specified in ADR 4/... or

             2.                         a 'Lap-Sash Belt' equipped with an 'Emergency Locking Retractor' as specified in ADR 4/... .

     5.                                     Seatbelt Anchorages

         1.                               'Seats' must be equipped with seatbelt 'Anchorages' which for:

             1.                         all front-facing 'Seats' must have anchorages for pelvic and upper torso restraint, as specified in clause 11, and

             2.                         all rear-facing 'Seats' must have anchorages for pelvic restraint and, if fitted with a 'Lap-sash' seatbelt, upper torso restraint as specified in clause 11.

         2.                               All 'Anchorages', whether on front-facing or rear-facing 'Seats', must be able to withstand the forces resulting from the tests specified in clause 7 or Appendix 1.

         3.                               All 'Anchorages', including the 'Final Torso Anchorage', must be mounted on the 'Seat', except where the 'Seat' does not form the head impact zone of another 'Seat' behind it as determined by clause 1 of Appendix 2.

     6.                                     Provision for Child Restraints

         1.                               At least six 'Seats' in the vehicle must be provided with 'Child Restraint Anchor Fittings' or, at the 'Manufacturer's' option, 'Child Restraint Anchorages' and 'Child Restraint Anchor Fittings' meeting the requirements specified in ADR 34/...
