20150366729Elevator Chair - Described are chairs having a seat with a sitting location above the floor, a base that sits on a floor, a lift connecting the seat and the base, the lift capable of moving the seat up and down from the sitting location to a lower location at the floor, and a control system operating the lift. The control system allows an occupant of the chair to move the seat between its sitting location and the lower location at the floor to enable the occupant to pick up or place an item on the floor while sitting in the chair and thereafter to move the seat upwardly.12-24-2015
20160022039MEDICAL SUPPORT APPARATUS - A chair includes a seat, a backrest, and a leg rest. A tilt actuator and lift actuator tilt and lift the seat, respectively. A leg rest actuator extends and retracts the leg rest. A backrest actuator pivots the backrest with respect to the seat. A controller simultaneously controls the actuators such that they move sequentially between multiple predefined states. A control panel enables a user to automatically move the chair to any of the predefined states. Progress indicators are included that provide a visual indication of how far the chair has progressed to a commanded state. A controller controls the actuators such that they simultaneously arrive at each state. One or more functions on a control panel may also be automatically disabled and/or automatically enabled as the chair moves into or out of certain ones of the predefined states.01-28-2016

20110193373Zero-Wall Clearance Linkage Mechanism for a Lifting Recliner - A seating unit that includes a linkage mechanism adapted to move the seating unit between seat-lift, closed, extended, reclined, and seat-lift positions is provided. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a base plate fixedly mounted to a lift assembly, a back-mounting link rotatably coupled to the seat-mounting plate, a seat-adjustment assembly with a bellcrank, and a linear actuator for automating adjustment of the linkage mechanism. In operation, a stroke in a first phase of the linear actuator generates a force on the bellcrank that translates the seat-mounting plate rearward in a consistent angle of inclination and rotates the back-mounting link from a reclined to an upright orientation. A stroke in a second phase acts to collapse the footrest assembly. A stroke in a third phase causes the lift assembly to raise and tilt the seating unit, thereby accommodating egress and ingress of an occupant.08-11-2011
