66.2.5.4.                    A 'Seat' with no other 'Seat' behind it is required to withstand a horizontal longitudinal force of 10 times the weight of the 'Seat' together with the loads of any seat belts mounted on the 'Seat'.
66.2.6.                          'Seats' convertible to a sleeper/bunk shall also meet the requirements of the rule in their sleeper/bunk configuration.

66.2.7.                          A Hybrid III manikin may be used in lieu of the Hybrid II manikin referred to in this rule.
66.2.8.                          Paragraph 3.2.5 in Annex 4 of Appendix A specifies a force equal to at least 20 N.  For the purposes of this rule the force is to be  40  + 20 N.

Paragraph 1.1 of Appendix A specifies requirements for 'Seats' which are installed on horizontal planes not differing by more than 6 cm from the floor level of the other forward-facing 'Seat' immediately in front of it.  Where the difference in height is more than 6 cm the rearmost 'Seat' shall be considered as a 'Seat' coming within the provisions of clause 66.2.5 and shall either meet the requirements of clause 66.2.5 or shall meet the intent of this Rule to the satisfaction of the 'Administrator'.
66.3.                                ALTERNATIVE STANDARDS
