Abstract
The convertible wheelchair is similar to a conventional wheelchair, but includes a reclining back support and an additional leg support plate. As the back support is pivoted, with respect to the seat, into a reclining position, the leg support plate is driven to pivot upward. When the back support is pivoted into a fully reclining position, the seat, the back support and the leg support plate are positioned parallel and co-planar with respect to one another. Similar to a conventional wheelchair, the convertible wheelchair includes a frame, the seat, which is secured to an upper end of the frame, the back support, which is secured to a rear end of the frame and is pivotally coupled to the seat, a pair of rear wheels rotatably secured to the rear end of the frame, and a pair of front wheels rotatably secured to the front end of the frame.
