Houdini 22

Separate body harness and seat fixing strap

Vehicle positioning harness for children and adults with special needs such as Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), Down Syndrome, Asperger’s disorder, developmental delay or other challenging behavioural needs where the person has problems with attention and safety. Providing safer travel and management of these loved ones when travelling in the car or other means of transport.


Alternatively, this harness can also be used to offer postural support and assist in seating the occupant in an upright sitting position for persons with physical disabilities such as Cerebral Palsy (CP) and other significant physical disabilities or complex needs where extra support and positioning is required during travel.

The body harness is worn before entering the vehicle. It is fitted with a waist belt and chest strap which fasten behind the passenger’s back with side-release buckles.

This harness will fit both single and bench seats. Suitable for bus, plane and taxi travel and children in Hip Spicas!

Access is required where the seat back joins the seat cushion as a ‘gap’ is necessary to pass the vertical fixing strap through from the front to the rear of the seat back.



Please note, to comply with safety regulations, the vehicle safety belt must always be worn over the top of the harness. The combination of the existing vehicle safety belt and the secondary harness offers added security for the passenger.

It is advisable to carry out a safety and risk assessment to first consider the problems involved and what the situation would be if the passenger is not wearing a special needs harness. Could they be in danger to themselves and to other passengers in the vehicle or even other drivers on the road if they are not safely seated during travel?

safety webbing slicer is included with every vehicle harness and must be kept in the vehicle as a safety precaution.

Does this harness require a vehicle tether point?




No. This harness does not require any tethering; it is not a safety harness. It is simply attached to the vehicle seat with the securing straps.


If I can’t pass the strap between the seat and the backrest, what can I do?



This can be common. Most vehicles have a carpet flap at the rear which prevents the straps coming vertically around the seat. In virtually all cases the carpet can be cut with a pair of scissors or a knife to provide access through.

I just wanted to let you know that the car harness has been a great success with my client and  it has made an enormous difference to his quality of life and especially his ability to get out of the house and back to school this term.

The Houdini 22 is working really well for this active client. What the family really loves about it is, it only has 2 buckles when attaching him into the car. This child gets agitated if it takes too long to transfer him in or out of the car, and this harness is really quick to use. We put the torso section of the harness on him inside the house (where he can’t run away) and then hold on to the harness while walking him out to the car and just click it in. We love this as it is really easy to use. When he gets to school, he is always in a hurry – we just unclick it and he runs into the classroom and the teacher takes the harness off!
