ABSTRACT:
An improved inflatable cushion lift assembly for use in a bathtub by a person taking a bath. The lift assembly is positioned on the floor of a bathtub and is connected to the bathtub faucet to inflate the cushion. The cushion may be deflated while a person is sitting thereon to lower a person to the floor of the tub. Furthermore, the cushion may be inflated while the person is sitting on the cushion on the floor of the tub to raise the user upwardly to allow the user to exit the tub easily. The present improvement inhibits undesired movement of the cushion while being used by utilizing a rigid bottom panel and/or rigid top panel. Furthermore, the interior of the cushion may be provided with baffles or the like for dampening water oscillations within the cushion. The cushion, for reasons of stability, may also be tiered or formed in layers such that the cushion inflates or deflates in stages. In another embodiment, the cushion may be placed in a rigid chairlike structure having an apparatus on the chair back which cooperates with a side wall of the cushion to guide the cushion during raising or lowering thereof. In yet another embodiment, a foldable valve is provided for effecting controlled discharge of the water within the cushion.
