摘要： A chair construction and method for building a chair having selected features are provided. The construction includes a plurality of interchangeable different components including different base assemblies, back assemblies, seats, arms, and chair controls that can be selected to provide different features on a "customized" chair. The different chair controls are constructed from a selected one of a plurality of interchangeable energy modules and a selected one of a plurality of interchangeable seat support modules. All components include standardized connections for engaging the related components, and further include various mechanisms and designs so that by selecting particular components, a chair having various features and appearances can be provided. For example, the plurality of interchangeable seat support modules include a non-adjustable seat support module, a seat-angle-adjustable seat support module, and a seat-depth-adjustable seat support module. Also, the plurality of interchangeable chair control modules include a non-lockable energy module, a back lockable energy module, and a multi-position backstop energy module, each connectable to a selected one of the aforementioned seat support modules. The modularity of these components facilitates assembly including on-site assembly, repair, and post-assembly upgrading of the chair. Further, the seat support is connected by removable pivot pins to allow assembly, retrofit and/or modification in the field. The tension adjustment mechanism, the seat height actuator mechanism, and the pivot connections are constructed for durability, performance, assembleability, compactness of design, and to minimize the number of and complexity of parts. The method includes selecting modules from a menu of interconnectable/interchangeable modules to construct a chair control, and further selecting modules from a menu of interchangeable components to construct a chair having selected features.

摘要： A seating unit is provided having a base assembly, 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. The seat includes a front section adjustably and/or flexibly supported on a rear section for optimal comfort while supporting a seated adult user's thighs, With the rear section being configured to carry a majority of the weight of a typical seated adult user. 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 back construction for a seating unit includes a back frame, and a compliant back having a forwardly-protruding lumbar support section that is characteristically flexible and bendable, such that the compliant back can be flexed to a plurality of different convex shapes. Top and bottom connections pivotally connect the compliant back to the back frame. An adjustable force-generating mechanism is operably attached to at least one of the compliant back and the back frame. The force-generating mechanism is constructed to provide an adjustable biasing force that adjustably biases the lumbar support section forwardly for optimal lumbar support for a seated user's back, but the force-generating mechanism characteristically provides the biasing force without forcing a shape change in the compliant back. A vertically adjustable lumbar support is slidably attached to the back shell.

摘要： A back for a seating unit, such as a chair, includes a back frame and a compliant back that is flexibly bendable to define different curvilinear shapes for sympathetically and ergonomically supporting a seated user's back. The back includes a belt bracket with forwardly-extending flanges pivotally connecting the back to the back frame at a first connection generally aligned with a seated user's hip joint. The back includes a second connection pivotally connecting the back to the back frame at a second location spaced vertically above the first connection. An adjustable force generating mechanism is connected to the first connection that biases a lumbar portion of the back forward with respect to the chair. The first and second connections, in combination with the adjustable force generating mechanism, constrain the compliant back to move over a range that provides excellent ergonomic lumbar support to a seated user.
