Abstract

See full text

A multifunction wheelchair, with fixed or folding frame, is described. The multifunction wheelchair is reconfigurable, by a transformation mechanism, between a normal use, ergonomic configuration and a roll-over-toilet configuration. This transformation involves raising the seat of the wheelchair, as needed, to position the wheelchair over the determined height of a toilet, and opening a seat closure mechanism to expose a cutout in the seat for toilet use. This transformation may be at least partially automated. In examples, the multifunction wheelchair is equipped with electronics (e.g., camera, microcontroller) to determine the toilet seat height for making height and/or steering adjustments. The transformation mechanism may be provided as a retrofit kit.
