Houdini 28 Harness

Due to the lack of knowledge and research about specialty harnesses/vests, the AuSAP Expert Committee recommended that research be undertaken to inform the inclusion of specialty harnesses/vests in future work programs.

This research includes an Austroads project (completed March 2025) and research by Neuroscience Research Australia (to be published later in 2025).

• This harness is registered with the Australian Therapeutic Goods Administration as a Class 1, Medical Device (ARTG No. 199851).
• Refer to instruction manual for information about compliance with overseas directives, standards and regulations. MACA has not undertaken an independent review of this information.

Important information: As children do not generally achieve good vehicle seatbelt fit until they are 10-12 years of age, where suitable a child should travel in a child restraint system that is appropriate for their size and needs. MACA's national product register also includes a list of Australian standard car seats and special purpose car seats.

The manufacturer advises it is available in three sizes:

28 I: Up to 5 years

28 A: 5 to 8 years

28 C: 9 years to adult

• This harness must always be used with the vehicle's lap-sash seatbelt.
• Access is required between the seat back and seat cushion for fitting.
• Restrictive practice implications will need to be considered when prescribed for behaviours of concern.
• Refer to the Austroads report for information about the safe selection and use of specialty harness/vests. This report includes expert safety recommendations, and we are seeking funding to develop prescriber guidance materials.
