Abstract
A power lifting and tilting device is more universally adaptable for economic retrofitting to most types of chairs as assists for the infirm. Little or no floor clearance requirements are achieved with power driven rollers traveling oppositely inclined surfaces of the device to produce lifting and tilting action for alighting from and occupying the chair.
