ABSTRACT:
A powered lift assist toilet seat assembly is disclosed for assisting physically impaired persons in being raised from and lowered to a position above a conventional toilet to perform normal toilet functions. The seat assembly includes a movable platform having a central opening, a toilet seat secured over the opening, and a pair of handrails secured to the platform on both sides of the toilet seat. An arrangement of link members are pivotally connected between the movable platform and a lower frame for controlling a movement of the platform upon actuation of a drive member. The arrangement of link members is such that the movable platform is pivoted and moved forwardly when the platform is raised by actuation of the drive member. The arrangement of link members includes first and second link assemblies positioned on respective sides of the platform which are interconnected by a pair of transverse shafts to increase a load capacity and stabilize the platform during operation. A shock absorber mechanism is secured to the movable platform to provide a slow and safe lowering of the toilet seat in the event of a mechanical failure of the drive member.
