ADR 22/00 Standards/Australian Design Rules for Vehicles as made
A vehicle standard determined under section 7(1) of the Motor Vehicle Standards Act 1989 providing requirements for head restraints in road vehicles.
Administered by: Infrastructure, Transport, Regional Development and Communications
General Comments: This standard was originally made under section 7 of the Motor Vehicle Standards Act 1989 and from 1 July 2021 continues in force as if it were a national road vehicle standard determined under section 12 of the Road Vehicle Standards Act 2018 (see Schedule 3, Part 2, item 2 of the Road Vehicle Standards (Consequential and Transitional Provisions) Act 2018).

This standard repeals each vehicle standard with the name Australian Design Rule 22/00 — Head Restraints that is: (a) made under section 7 of the Motor Vehicle Standards Act 1989; and (b) in force at the commencement of this standard. This standard also repeals each instrument made under section 7 of the Motor Vehicle Standards Act 1989 that creates a vehicle standard with the name Australian Design Rule 22/00 — Head Restraints, if there are no other vehicle standards created by that instrument, or amendments to vehicle standards made by that instrument, that are still in force at the commencement of this standard. The Motor Vehicle Standards Act 1989 is wrongly cited in this instrument as the "Motor Vehicles Standard Act 1989".

A.                    legislative provisions

A.1.                 NAME OF STANDARD

A.1.1.              This Standard is the Vehicle Standard (Australian Design Rule 22/00 – Head Restraints) 2006.

A.1.2.              This Standard may also be cited as Australian Design Rule 22/00 — Head Restraints.

A.2.                 COMMENCEMENT

A.2.1.              This Standard commences on the day after it is registered.

A.3.                 REPEAL

A.3.1.              This Standard repeals each vehicle standard with the name Australian Design Rule 22/00 — Head Restraints that is:

                        (a)        made under section 7 of the Motor Vehicles Standard Act 1989; and

                        (b)        in force at the commencement of this Standard.

A.3.2.              This Standard also repeals each instrument made under section 7 of the Motor Vehicles Standard Act 1989 that creates a vehicle standard with the name Australian Design Rule 22/00 — Head Restraints, if there are no other vehicle standards created by that instrument, or amendments to vehicle standards made by that instrument, that are still in force at the commencement of this Standard.

b.                    SCOPE

The function of this vehicle standard is to specify requirements for the design of ‘Head Restraints’ so as to limit the severity of injury in the event of rear-end impacts and to ensure that the ‘Head Restraint’ cannot be adjusted too low.

c.                    APPLICABILITY AND IMPLEMENTATION

C.1.                 Applicability Summary

This vehicle standard applies to the design and construction of vehicles as set out in the table below.

22.1.                                DEFINITIONS

22.1.1.                          Refer to Vehicle Standard (Australian Design Rule Definitions and Vehicle Categories) 2005.

22.2.                                PROVISION, LOCATION AND SIZE

22.2.1.                          A ‘Head Restraint’ must be provided for each front ‘Outboard Seating Position’.  It may be provided with vertical and lateral adjustable mounting, and may be removable without the use of tools.

22.2.2.                          The ‘Head Restraint’ must be so designed that:

22.2.2.1.                    it presents an impact surface which extends between 2 planes not less than 115 mm apart and normal to the ‘Torso Line’; and

22.2.2.2.                    the upper boundary of the impact surface is not less than 700 mm above the ‘Seating Reference Point’ measured along the ‘Torso Line’, for any position of adjustment which may be provided.

22.2.3.                          The width of the ‘Head Restraint’ must be not less than 250 mm for use with bench ‘Seats’ and not less than 170 mm for use with individual ‘Seats’ when measured between heights of 585 mm and 635 mm above the ‘Seating Reference Point’ and along the ‘Torso Line’.

22.2.4.                          The ‘Head Restraint’ must be so constructed and contoured to decelerate horizontal movements of the head without concentrations of load on it.

22.3.                                TEST REQUIREMENTS

22.3.1.                          The ‘Head Restraint’ must meet the conditions of either a dynamic or static test.

22.3.2.                          In the dynamic test, acceleration of the seat supporting structure of up to 8 times the acceleration due to gravity, must not produce an angular displacement of the ‘Head Reference Line’ of more than 45o.

22.3.3.                          In the static test the rearmost point of the head form must not be displaced to more than 102 mm perpendicularly ‘Rearward’ of the displaced extended ‘Torso Line’ during the application of the load specified in clause 22.5.3 nor must the ‘Head 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 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.  For vehicles which have an ECE approval to R17, the approval must be for vehicles with ‘seats’ fitted with, or capable of being fitted with a ‘head restraint’
