  • Publication number: 20110121625
    Abstract: The present invention is a chair having a first seat portion operably associated with a second seat portion, with the first seat portion disposed in the same plane as the second seat portion when the chair is in a lowered position, and an actuator for moving the first seat portion relative to the second seat portion. When the actuator is actuated, the first seat portion pivots relative to the second seat portion such that the first seat portion is located in a different plane compared to the second seat portion. When in the raised position, the first seat portion is substantially parallel to the ground, which allows the occupant of the chair to easily transfer the occupant's center of gravity to being supported by the occupant's feet and knees.

  • Patent number: 5865457
    Abstract: A wheeled reclining chair is provided which includes an improved swing link assembly for permitting the seat back assembly to recline approximately 180.degree. relative to the seat assembly to provide a substantially flat occupant-supporting surface such that the seat back provides a rearwardly extending cantilevered surface and the leg rest assembly provides a forwardly extending cantilevered surface from the chair frame assembly. The swing linkage assembly includes a pair of front slide assemblies and a pair of rear swing linkage mechanisms which suspend and operably couple the seat assembly to the chair frame for providing the desired reclining motion. A mobile base assembly having front and rear wheels which can be removed from the base assembly is also provided. The wheeled reclining chair includes a tilt linkage mechanism for tilting the chair frame relative to the mobile base assembly.
