No. Not every wheelchair is designed or tested to be used as the occupant’s seat in a motor vehicle. When a passenger remains seated in a wheelchair during vehicle travel, the wheelchair itself becomes part of the transportation safety system and its suitability for that use needs to be considered.
What is a transport-ready wheelchair?
A wheelchair intended for use as a seat in a motor vehicle may include designated securement points, transportation labelling and manufacturer instructions. Standards such as ISO 7176-19 and WC19 address wheelchairs intended for this type of use.
Does a transport-ready wheelchair still need wheelchair securement?
Yes. A wheelchair designed for vehicle-seating use still requires the appropriate wheelchair securement and occupant restraint system for the application. The wheelchair and the WTORS answer different safety questions.
What is the difference between WC18 and WC19?
WC18 addresses wheelchair tiedown and occupant-restraint systems. WC19 addresses wheelchairs intended for use as seats in motor vehicles. A complete transportation setup may therefore involve requirements relating to both the wheelchair and the WTORS.
What should I look for on the wheelchair?
- Manufacturer transportation instructions
- Designated securement points or transport markings where provided
- Information about use as a seat in a motor vehicle
- Limitations relating to seating systems, accessories or powered functions
What about powered wheelchairs and scooters?
Powered mobility devices can be heavier and structurally more complex than manual wheelchairs. Batteries, tilt/recline systems, removable components and accessories can affect securement and occupant-restraint access. Read the wheelchair manufacturer’s transport instructions and seek technical guidance where the correct securement method is unclear.
Can wheelchair brakes secure the wheelchair in a vehicle?
No. Parking brakes help control wheelchair movement during normal use but are not a substitute for a vehicle wheelchair securement system designed for transport loading.
Can the wheelchair’s own lap belt be used as the vehicle seat belt?
Not automatically. A wheelchair postural belt is commonly intended for positioning. It should only be treated as part of the vehicle crash-restraint system where that function is specifically supported by the relevant design, testing and manufacturer documentation.
What should vehicle builders and engineers consider?
The wheelchair, occupant, WTORS and vehicle layout should be considered together. Shoulder-belt geometry is particularly sensitive to wheelchair position and occupant size. The Estraints Wheelchair Restraint Calculator supports calculation and documentation of upper shoulder-belt anchorage geometry.
