I saw nothing wrong in the thread, maybe I missed something.
I have a Convaid chair and it is rated for Transport, and can safely be tied down in school busses, or public busses. It has special handle things that allow this. Plus it came with a harness that would have to be used as well I think. (We removed it, since we do not use even the seatbelt for him.)
He is 19, and we fold it up for busses. Sean is 19, but he is autistic and would FREAK out if we tried to load him onto a bis while he stayed in the chair....... I often drive though to the parks, and park in the handicapped area, because trams would be very difficult.
Have a great time at Disney, no matter what!!
This is some Convaid info:
Because there are no Federal Motor Vehicle Safety Standards for wheelchairs used as seating in a motor vehicle, the SOWHAT* Committee, under the auspices of ANSI*/ RESNA* and ISO*, developed a voluntary industry standard. That industry standard is commonly known as "WC/19"*. WC/19 addresses issues of wheelchair design and performance related to its use as seating in a motor vehicle, such as a bus or van. WC/19's purpose is to improve the safety and security of wheelchair-seated occupants of motor vehicles during normal transportation, but especially in the event of a vehicle crash. Therefore, WC/19-compliant wheelchairs, or "transit" wheelchairs, are equipped with an array of features, such as anchor points for securing the wheelchair to the frame of the bus or van and an attachment point for occupant restraints to protect the safety of the wheelchair occupant. Labeling and documentation are also an important part of the WC/19 standard.
