Restraint' fail before a failure of the 'Seat' back or alternatively before the load has reached 890 N.
22.4.                                DYNAMIC TEST CONDITIONS
22.4.1.                          For testing compliance with clause 22.3.2 a dummy having the mass and seated height of a '95th Percentile Adult Male' and with an 'Approved' representation of a human articulated neck structure must have lines marked to represent the 'Torso Line' and, by extension, the 'Head Reference Line'.
22.4.2.                          A dummy meeting the requirements of clause 22.4.1 must be placed in the seating position under test and restrained by a seat belt providing upper torso restraint.
22.4.3.                          A 'Forward' acceleration must be applied to the 'Seat' supporting structure.  When graphically depicted, the magnitude of the acceleration curve must not be less than that of a half-sine wave having the amplitude of 8 times the acceleration due to gravity and a duration of 80 milliseconds and not more than that of a half-sine wave having an amplitude of 9.6 times the acceleration due to gravity and a duration of 96 milliseconds.
22.5.                                STATIC TEST CONDITIONS
22.5.1.                          For compliance with clause 22.3.3 a test device must be selected having back pan dimensions and 'Torso Line' of the 3-dimensional manikin specified in the SAE documents "Manikins for Use in Defining and Measuring Vehicle Seating Accommodation", November 1962 or J826 APR90- "Devices for Use in Defining and Measuring Vehicle Seating Accommodation" (provided that the back pan dimensions are as specified in J826 - November 1962).
22.5.2.                          To establish the displaced 'Torso Line', a test device must be placed in the seating position under test and a 'Rearward' moment of 370 Nm about the 'Seating Reference Point' must be applied through the back pan.
22.5.3.                          After removing the back pan, using a 165 mm diameter spherical head form or a cylindrical head form having a 165 mm diameter in plan view and a 150 mm height in profile view, apply perpendicular to the displaced extended 'Torso Line', a 'Rearward' load, at a point 635 mm along the 'Torso Line' from the 'Seating Reference Point' that will produce a 370 Nm moment about the 'Seating Reference Point'.
22.5.4.                          The load must be gradually increased to 890 N or until the 'Seat' back fails, whichever occurs first.
22.6.                                ALTERNATIVE STANDARDS
22.6.1.                          The technical requirements of ECE R 25/01, 25/02, 25/03 or 25/04 - "Head restraints (Headrests)" and FMVSS 202-33 F.R.  15065, October 9, 1968 "Head restraints - Passenger Cars" are deemed to be equivalent to the technical requirements of this rule provided that the requirements of clauses 22.2.2, 22.2.3 and 22.2.4 are complied with.
22.6.2.                          The technical requirements of ECE R 17/03, 17/04 or 17/05 "Seats, their Anchorages and any Head Restraints" are deemed to
