    摘要: A seating unit is provided having a base assembly with a particularly shaped housing and rigid upright side arms, a back frame pivoted to the base assembly for movement between upright and reclined positions, and a seat slidably supported on the base assembly and pivoted to the back frame so that the seat moves forwardly and its rear moves forwardly and downwardly with the back frame upon recline. A flexible back is connected to the back frame at top and bottom locations and is provided with lumbar adjustment for improved lumbar force/support and shape. A seat is provided with seat depth adjustment and with active and passive thigh flex support. A novel energy mechanism is provided that includes a moment arm shift adjuster for adjusting the spring tension on the back frame. The moment arm shift adjuster is readily adjustable and includes an overtorque device to prevent damage to components of the energy mechanism.

    摘要: A chair includes a back frame and a flexible back support operably supported on the back frame. The flexible back support includes a flexible lumbar region and a flanged bracket pivotally connected to the back frame at a back support pivot. A force adjusting device is attached to the back frame at the back support pivot for adjusting a torsional spring-generated biasing force on the flanged bracket relative to the back frame. The force adjusting device includes a housing, a base attached to the housing, a spring operably mounted in the housing, and a gear arrangement operably connected to a cup-shaped handle to biasingly adjust a position of the spring with mechanical advantage to adjust a tension of the spring. A clutch is operably attached between the gear arrangement and the handle. The clutch is constructed to lock when a biasing force is received from the back support, but is configured to release and allow movement of the handle and the gear arrangement to adjust a tension of the spring when the handle is moved.

    摘要: A seating unit includes a mechanism for adjustably positioning a component of the seating unit. The mechanism includes first and second members, each having a generally smooth curvilinear load bearing surface and a plurality of teeth adjacent the load bearing surface. The load bearing surfaces are in contact to transfer load, and the teeth of the first and second members are in engagement to provide non-slip rotation.

    摘要: A chair includes a base having a vertically extendable gas spring with an upwardly disposed release button movable horizontally/laterally between a vertically oriented locked position where the gas spring is lock and non-extendable, and a laterally shifted actuated position where the gas spring is released and extendable. A seat is mounted on the gas spring and includes an actuator constructed to selectively move the release button between the locked position and the actuated position with a sideways movement. The actuator includes a link slidably mounted to a control housing under the seat for horizontal movement, and a lever that is pivoted to a side of the control housing for operating the link. The link includes an aperture with angled side surfaces configured to facilitate downward assembly of the link onto the release button, but so that the side surfaces will actuate the release button when the link is moved laterally by the lever.

    摘要: An armrest construction for chairs includes an armrest support having a lower end constructed for attachment to a chair, an upper end, and a mounting block attached to the upper end. A pivot block is pivoted to the mounting block at a main pivot, the pivot block having an upwardly-extending follower. First and second gears are each pivoted to the pivot block, the gears having intermeshing teeth at an inner end such that rotation of the first gear causes the second gear to simultaneously rotate in an opposite direction, the first and second gears further having outer ends. A support plate having pivot/slide members engages the outer ends of the first and second gears, and further has a guide operably engaging the follower to guide lateral movement of the support plate along a predetermined path. The support plate is rotatable about the main pivot to adjust the angular orientation of the armrest construction and is laterally movable along continuously parallel positions to adjust a width of the armrest construction relative to the chair. The armrest construction is mounted on a vertically-adjustable armrest support member for optimal adjustability.
