To secure a wheelchair in a vehicle, use a suitable wheelchair tiedown or docking system to secure the wheelchair, then apply the appropriate occupant restraint to the person seated in the wheelchair. Wheelchair securement and occupant restraint are two separate safety functions within a WTORS.
Learn what WTORS means or use the Five-Check Wheelchair Securement Checklist.
What is the safest way to secure a wheelchair in a vehicle?
The correct method depends on the wheelchair, vehicle and securement equipment. Many general-use systems use four tiedowns, while compatible docking systems mechanically secure the wheelchair through a dedicated interface. Always follow the wheelchair and WTORS manufacturer’s instructions for the equipment actually fitted.
Step 1: Confirm the wheelchair is suitable for transport
Not every wheelchair is designed to be used as a seat in a motor vehicle. Check the wheelchair manufacturer’s transportation information and identify designated securement points where provided. Wheelchairs designed and tested for vehicle-seating use may reference standards such as ISO 7176-19 or WC19.
Step 2: Position the wheelchair correctly
Position the wheelchair in the orientation and location intended for the vehicle and restraint system. The operator needs access to the securement points and occupant restraint without creating poor belt routing around wheelchair components.
Step 3: Secure the wheelchair
Four-point tiedowns
A typical four-point system uses two securement connections toward the front of the wheelchair and two toward the rear. Attach them only to suitable wheelchair securement points and suitable vehicle anchorages.
Docking systems
A docking system uses a compatible wheelchair-side and vehicle-side interface. Confirm the wheelchair is correctly aligned and that the system indicates full engagement in accordance with the manufacturer’s instructions.
Wheelchair parking brakes can assist with normal stability, but they are not a substitute for vehicle wheelchair securement.
Step 4: Apply the occupant restraint
The person seated in the wheelchair requires the appropriate occupant restraint. This is separate from the equipment securing the wheelchair.
The pelvic portion should contact the occupant appropriately and should not be held away from the body by armrests, wheels or other wheelchair structure. The upper-torso restraint should pass over the shoulder and across the chest in the intended belt path.
Do not assume a wheelchair postural belt is a vehicle crash restraint unless its transport-restraint function is specifically supported by the applicable product documentation.
Step 5: Check the complete system
- All required wheelchair securement connections are fitted or the docking system is fully engaged.
- The wheelchair is stable and positioned as intended.
- The pelvic restraint is routed appropriately.
- The shoulder belt is positioned on the occupant rather than behind the wheelchair or off the shoulder.
- Webbing, fittings, buckles, retractors and anchorages show no obvious defects.
Common wheelchair securement mistakes
- Attaching tiedowns to armrests, wheels or removable wheelchair components
- Leaving one of the required securement points disconnected
- Twisted or badly routed webbing
- Treating wheelchair brakes as the primary securement
- Routing the pelvic belt over an armrest
- Routing the shoulder belt behind the wheelchair backrest
- Using damaged webbing or hardware
- Improvising because the correct attachment point cannot be identified
When should you stop and seek advice?
Stop and escalate the issue if a suitable securement point cannot be identified, the restraint cannot be positioned appropriately, equipment is damaged, a docking system will not engage or the wheelchair configuration prevents the WTORS from being used as intended.
Which standards apply to wheelchair securement?
Relevant standards can include ISO 10542-1, AS/NZS 10542.1, RESNA WC-4 Section 18, SAE J2249 and CSA Z605. The correct framework depends on the jurisdiction and application.
Need to assess shoulder-belt geometry?
If you design, install or assess wheelchair accessible vehicles, the Estraints Wheelchair Restraint Calculator helps calculate and document upper shoulder-belt anchorage geometry.
