Patent abstract
An electrically-operated personal canopy apparatus is configured for attachment to the back of a wheelchair to provide rain protection for a user. The movements of various mechanical elements of the apparatus are controlled so that a single user input causes a free end of a spine to extend from a storage container to a position above the user and a fan-fold canopy to then open.
