Abstract: A patient repositioning system intended for a patient confined to a bed for an extended time period. The repositioning system includes a sling attached to a frame with side poles having head and foot segments that passively fold between a flat/supine position and sitting positions. The frame pivotally mounts to a frame base that is anchored or affixed to a bed. The frame can be pivotally lifted off of a bed mattress, either uniformly by a single-actuator lifter raising both frame poles by the same angle, or so as to tilt the frame to assist with turning a patient by a dual-actuator lifter raising the frame poles to different angles.
