  • Patent number: 6397409
    Abstract: A bath lift system comprises a seat which is raised and lowered inside of a bath by a lifting device positioned inside the bath. The lifting device provides an aesthetically appealing system with the seat substantially concealing the lifting device, thus obscuring its view. The lifting device reduces leakage while providing straight line movement positioning of the seat from a central position to a position along side of the top rim of the bath. Also, an alternative internal lifting device that eliminates the need for openings through the wall of the bath is provided.
