  • Patent number: 11607046
    Abstract: A mechanism for raising and lowering an armrest for a seat includes an armrest, a rotatable hub, and an actuating linkage between the armrest and the hub, the rotatable hub having a cam that operates the actuating linkage to raise the armrest wherein the cam can rotate through a first angle of rotation where the actuating linkage is not operated a second angle of rotation where the actuating linkage is operated. The cam can rotate through a third angle of rotation where the actuating linkage is not operated, this angle being different to the first angle of rotation. The cam is torsionally linked to the rotation of a seat member.

  • Publication number: 20090212607
    Abstract: A seating unit includes a tubular support extending upwardly from a chair frame, a retainer telescopingly engaging an upright open end of the support, and an armrest mounted on the retainer. The retainer is keyed at both ends to prevent undesired rotation of the armrest. Accessories are mounted to the retainer, and are positionable at use and non-use positions relative to a seated user. The accessories include a cup holder, a container, a hook for hanging items under the cup holder or container, and different tablets. One tablet includes a wheeled leg that extends downwardly from a center of gravity of the tablet, the leg supporting the tablet and reducing cantilever forces on the retainer. The back and seat comprise a flexible member co-molded onto a supportive partial-perimeter frame member and includes back and seat sections that matably engage corresponding surfaces of the frame member.
