Abstract
A barrier-free wheelchair constructed entirely of plastic or non-metal components. The device is designed to facilitate the passage of wheelchair occupants through magnetometers, such as those utilized for airport security. The present invention is non-collapsible in nature, as the device is intended for on-site usage and not for transport in vehicles and the like. Due to its materials and construction, the wheelchair of the present invention also allows for a solid non-sling seat, is pilferage resistant, and provides multiple surfaces upon which indicia, such as corporate graphics, may appear. In addition, consistent with pre-existing wheelchairs, the present invention allows for the removable attachment of a variety of accessories, including foot rests and trays.
