34.0.1. NAME OF STANDARD
34.0.1.1. This Standard is the Vehicle Standard (Australian Design Rule 34/00 – Child Restraint Anchorage and Child Restraint Anchor Fittings) 2006.
34.0.1.2. This Standard may also be cited as Australian Design Rule 34/00 — Child Restraint Anchorage and Child Restraint Anchor Fittings.
34.0.2. COMMENCEMENT
34.0.2.1. This Standard commences on the day after it is registered.
34.0.3. REPEAL
34.0.3.1. This Standard repeals each vehicle standard with the name Australian Design Rule 34/00 — Child Restraint Anchorage and Child Restraint Anchor Fittings that is:
(a) made under section 7 of the Motor Vehicle Standards Act 1989; and
(b) in force at the commencement of this Standard.
34.0.3.2. 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 34/00 — Child Restraint Anchorage and Child Restraint Anchor Fittings, 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.
A. Function and SCOPE
The function of this Australian Design Rule is to specify requirements for ‘Child Restraint Anchorages’ and ‘Child Restraint Anchor Fittings’ to provide for the connection of standard ‘Attaching Clips’ so that ‘Child Restraints’ may be adequately secured to the vehicle.
B. APPLICABILITY
B.1 This ADR applies to the design and construction of vehicles as set out in the table below.
B.3 This ADR replaced the ‘Child Restraint Anchorage’ requirements in Section 5.11 of ADR 5/02. It aligns the requirements for ‘Child Restraint Anchor Fittings’, ‘Attaching Clip’ and their respective mating surfaces with those in the revised Australian Standard AS 1754 - 1991.
B.3 # For MD3, MD4, and ME vehicles the circumstances under which ‘Child Restraint Anchorages’ are mandatory are set out in ADR 68/.. .
