Abstract: A seating unit includes a base, a reclineable back, a seat, and a control operably supporting the back and the seat on the base for movement between upright and recline positions. The control includes a pair of flexible support members and a link that combine to operably support the seat and back for synchronous movement on the base upon recline. The flexible support member is stiff in a vertical direction for carrying a combined weight of the one component and of the seated user, but flexible in a horizontal direction to permit a swinging movement of its ends upon recline. The link is rigid and pivoted to the base for movement about a horizontal axis and also pivoted to the one component. By this arrangement, the flexible member and the link move the one component along a defined path during recline of the back.

Abstract: An armrest includes an armrest support and a subassembly supported thereon for vertical adjustment by a height adjustment device having a rotatable high-lead-angle threaded shaft, a mating nut, and a trigger. The shaft member is rotatable upon a vertical force being placed on the subassembly, and the trigger engages the shaft to prevent rotation and fix a selected height position. The subassembly includes a housing, an armrest cap, and a pair of swing arms pivoted to each of the housing and cap for adjustably supporting the armrest cap for rotational and translational horizontal movement. Horizontal adjustment is controlled by choice of materials, a frictional wave spring and dampener. Optionally, the armrest cap includes a keyhole slot and one of the links includes a configured protrusion shaped to selectively linearly slide along a long part of the slot or rotate in the circular end of the keyhole slot.

Abstract: A chair includes a lower back frame, a back construction, including a back support attached to the lower back frame, a cushion assembly attached to the back support, and a vertically adjustable lumbar. The lumbar frame includes a transition shell and a vertically sliding lumbar device having a plurality of horizontal flexible wires. A lower edge of the transition shell is positioned on top of an uppermost horizontal flexible wire of the lumbar device. The lumbar device is operably slidably mounted between the outer shell and cushion assembly and the transition shell upper edge slides between the outer shell and the upholstery cushion assembly. Another chair includes a Y-shaped lower back frame having two uprights and a cross-piece attached to the back support. An overlap flange and channel-shaped flange mate to form an overlap joint, including a box beam for added structural support.

Abstract: A vertically adjustable armrest includes a tubular support constructed for attachment to a chair, an armrest assembly telescopingly positioned in the tubular support, and a height adjustment mechanism slidably received in the armrest assembly. The armrest assembly includes a sleeve and a post. The height adjustment mechanism includes an actuator rod, an operative member, a locking member, and a resilient member. The actuator rod operatively engages the locking member with the inclined wedge mateably engaged with the inclined surface and the angled surfaces slideably engaged with the lateral followers. To vertically adjust the armrest, the operative member is lifted upward, causing the resilient member to compress and the teeth of the locking member to disengage from the detents. To reengage the teeth with the positional detents, the operative member is released.
