Abstract: A powered auxiliary toilet seat lift provides a U-shaped casement formed by two similar elongate side members interconnected by a forward end plate to fit about a toilet stool and support a toilet seat structure thereabove for vertical and forwardly and downwardly angulated motion. Each casement side member is peripherally defined to create an internal chamber carrying similar elongately spaced lateral pairs of forward and rearward compound jackscrews that pivotally interconnect with the toilet seat structure thereabove. Powering mechanism provides separate electric motors powering each jackscrew that are controlled by a computerized feedback type circuitry for manually selectable or pre-programed motion of the toilet seat structure.
