* “Lateral stability” is the displacement of point P (the center of gravity on the loaded wheelchair)
when a platform with the loaded wheelchair is tilted 45º laterally from the horizontal. Higher numbers
indicate less stability.
This table refers to tests performed in accordance with WC-19 to establish lateral stability during
normal travel and the ease of use and proper fit of vehicle-anchored belt restraints. The letter
designation reflects the overall rating of the lap and shoulder belt position.
Using the EZ Rider Chair for Transportation in Motor Vehicles
The OPTIONAL Transit Version EZ Rider can transport users in motor vehicles that are compatible with
Occupant Restraint Systems (WTORS). The chair MUST be secured in a forward-facing position with a
Wheelchair Tie-down and Occupant Restraint System (WTORS), which meets the requirements of WC-4
or ISO 7176.
WARNING:
The wheelchair should be used as indicated in the User’s Guide
instructions accompanying the wheelchair. Failure to do so increases the
likelihood of serious injury in a vehicle crash.
WARNING:
Do not attach tiedowns anywhere except designated tiedown
locations.
WARNING:
During transit, chair must be forward facing with all accessories
removed.
WARNING:
Do not alter or substitute any part or component of the wheelchair,
wheelchair frame or wheelchair seating system.
