Abstract
Abstract The improved device is adapted to safely support a person, such as an invalid, in a bathtub and permit such person to wash in privacy without aid. It includes an adjustable support frame, preferably open, which can be adapted to snugly fit into the cavity of a bathtub, and a seat which is adjustable vertically and supported in the frame by adjustable interconnection between a depending seat post and an anchor post secured in the frame. A safety belt and/or guard rail may be provided to secure the bather in position on the seat. An extension of the seat top which is partly supported by the seat top and partly supported by a pair of collapsible legs is present in one embodiment of the improved device in order to safely support a portion of the torso of a paralyzed or otherwise enfeebled bather. A detachable ladder and detachable bath accessory rack may also be provided. Preferably the top and extension are porous, and are covered, as is the frame, with a protective resilient layer of rubber or the like. The device offers great convenience, safety and practicality for the care of invalids. It is foldable, compact and easy to use, store and transport.
