What Is a Four-Point Wheelchair Tiedown?
A four-point wheelchair tiedown secures a wheelchair to a motor vehicle using four separate securement connections, typically two toward the front of the wheelchair and two toward the rear.
How does a four-point tiedown work?
Each tiedown connects a suitable wheelchair securement point to a suitable vehicle anchorage or floor track. Together, the four connections control wheelchair movement relative to the vehicle.
Does a four-point tiedown restrain the passenger?
No. The tiedowns secure the wheelchair. The passenger still requires the appropriate pelvic and upper-torso occupant restraint.
Where should the tiedowns attach to the wheelchair?
Use designated transport securement points where provided or other suitable locations specifically supported by the wheelchair and WTORS manufacturer’s instructions. Do not attach tiedowns to removable or weak components simply because they are easy to reach.
Should wheelchair brakes be applied?
Wheelchair parking brakes can assist with normal stability, but they are not a substitute for the vehicle securement system.
What are common four-point tiedown errors?
- One required tiedown missing
- Tiedown attached to a wheel, armrest or removable component
- Twisted webbing
- Excessive slack
- Poor strap routing
- Using damaged webbing or fittings
How is a four-point tiedown different from docking?
A docking system secures a compatible wheelchair through a dedicated mechanical interface instead of four manually connected tiedowns. See Wheelchair Docking vs Four-Point Tiedowns.
