A toilet seat assembly is provided having a seat that is pivotably supported at its forward end for swinging movement between substantially horizontal and upwardly inclined positions. A power lift mechanism is incorporated in the assembly and is selectively operable by the user to pivot the seat and support the seat in a desired position for assisting the user in moving between seated and standing positions. The power lift mechanism includes an expandible bladder of the bellows disposed at the rear of the seat assembly between a base structure adapted to be secured on the top of a toilet bowl and the pivoted seat that is also mounted on the base structure. A fluid control system is coupled with the expandible bladder and adapted to be connected with a source of pressurized fluid and has a manually actuated control valve operable by the user to permit admission of pressurized fluid into the bladder to cause its expansion and upward pivoting of the seat or to permit outflow of fluid from the bladder resulting in construction of the bladder and pivoting of the seat towards a horizontal position.

A power lift toilet seat assembly comprising a base structure adapted for mounting on a toilet bowl in fixed relationship thereto, a toilet seat mounted on said base structure to extend when disposed in a first position in a substantially horizontal plane over said base structure, said toilet seat pivotably secured to said base structure for swinging movement in a vertical plane about a substantially horizontal pivot axis that extends transversely to a longitudinal axis of a toilet bowl on which the seat assembly is mounted between said first position and a second position angularly disposed to said position, said pivot axis disposed adjacent a forward end of said base structure, and fluid powered actuator means mechanically interconnected between said base structure and said toilet seat for effecting relative pivoting movement therebetween, said actuator means including a flexible-walled bladder disposed between said base structure and said toilet seat in rearwardly disposed relationship to said pivot axis and expandible between a relatively collapsed configuration when said seat is disposed in said first position and a proportionally expanded configuration when said seat is pivoted to a second position, and fluid circuit means connected in fluid communicating relationship with bladder for effecting expansion or contraction thereof to cause pivoting of said seat to a selected position said fluid circuit means including a control valve selectively operable to control the flow of fluid to or from said bladder, said base structure and seat are each formed with a central open area and have transversely extending rear end portions and side portions that are substantially superposed when said seat is in said first position, said bladder interposed between the respective rear end portions of said base structure and said seat.
