with the Australian Design Rule for "Anchorages for Seat Belts and Child Restraints".
3.2.1.1.2.                  Twenty times the weight of the entire 'Seat' in a 'Forward' longitudinal direction simultaneously with, where the 'Child Restraint Anchorages' are located in or on the seat-back, or are located in the vehicle body structure more than 100 mm below a horizontal plane tangential to the point on the top of the seat-back longitudinally 'Forward' of the 'Child Restraint Anchorage', a total load of 3.4 kN for each, imposed on the 'Seat' by simultaneous application to each 'Anchorage' by a flexible connection which passes over the top of the seat-back to the 'Child Restraint Anchorage'.  Each load shall be applied 'Forward' of the seat-back not more than 5o above or below the horizontal, and not more than 5o  to left or right of the longitudinal axis of the vehicle.
3.2.1.2.                        A load equal to 20 times the weight of the entire 'Seat' shall be applied in a 'Rearward' longitudinal direction.
3.2.1.3.                        A load equal to a 370 N.m moment about the 'Seating Reference Point' for each occupant position for which the 'Seat' is designed shall be applied to the upper cross member in a 'Rearward' longitudinal direction, unless it is demonstrated that 'Seat' assemblies such as rear seat-backs are supported by a vehicle body member capable of withstanding the nominated load.
3.2.1.3.1.                  Testing which meets the 370 N.m requirement by any one of the following 3 methods is acceptable:

3.2.1.3.1.1.            force applied horizontally;

3.2.1.3.1.2.            force applied normal to seat-back; or

3.2.1.3.1.3.            force applied longitudinally and 'Rearward' to the upper part of the seat-back frame through a component simulating the back of a 3-D manikin.

3.2.1.3.1.4.            If deflection of the seat-back causes the moment arm to change, the force should be adjusted to ensure that the moment value of 370 N.m is achieved.

3.2.2.                              The 'Seat Adjusters' need not be operable after the application of the loads specified in Clauses 3.2.1.1, 3.2.1.2 and 3.2.1.3.
3.2.3.                              Restraining Device for Hinged 'Seats' or Seat-backs
         3.2.3.0. Except for a 'Seat' having a back that is adjustable only for the comfort of its occupants hinged 'Seats' or seat-backs shall be equipped with a self-locking device for restraining the hinged 'Seat' or seat-back and a release control for releasing that restraining device to preclude the possibility of impact forces acting on unrestrained hinged 'Seats' or seat-backs.
3.2.3.1.                        Where the 'Seat' must hinge to permit access to or egress from another seating position, the release control shall be readily accessible to the occupant of that 'Seat' and to the occupant of any 'Seat' immediately behind that 'Seat'.
3.2.3.2.                        The restraining device (including the release control) shall be constructed to preclude inertial release when
