Abstract: For safely lifting an invalid to an elevated position in which the invalid's backside may be exposed for cleansing and in which the invalid may be transported over a floor, an invalid support assembly having a support frame with trunk, knee, and foot supports is mounted on a wheeled support for movement from a first, lower position in which an invalid in a seated orientation may be clamped to the support assembly to a second, elevated position in which the invalid is oriented in a generally prone position. Remotely controllable, battery-operated jacking units drive parts of a lever system for moving the invalid support assembly between its lower and elevated positions.
