A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

Body support member with lattice structure

A seat assembly includes a base and a support platform spaced above the base. The support platform includes a pad having a hinge portion defining a flex region, wherein the pad is pivotable about the flex region. A link has a lower portion coupled to the base and an upper portion coupled to the pad, wherein the upper portion is pivotable with the pad about the flex region.

Body support assembly and methods for the use and assembly thereof

A chair assembly includes a base assembly, a seat assembly having a pair of side edges and a fore-to-aft extending longitudinal centerline, a back assembly movable between upright and reclined positions, and an arm assembly including an arm base extending from a first location between the side edges to a second location laterally outward of one of the side edges, wherein the arm base extends at an acute angle with respect to the longitudinal centerline and at an upward angle from the first location toward the second location, a support assembly supported by and extending upwardly from the arm base, and an armrest supported by the support assembly that is adjustable to support the armrest between a plurality of selected vertical positions, wherein the arm assembly and back assembly move at a different rate from one another as the back assembly is moved between the upright and reclined positions.

Chair arm assembly

A body support structure includes a base, a seat and a backrest, with the backrest connected to the base with a torsion leaf spring. The torsion leaf spring may be configured with a plurality of fingers, and/or one or more flex regions. One or more struts may be connected between the seat or backrest and the base. In another aspect, the seat and/or backrest may be supported with one or more links that provide a counter-intuitive motion. In another aspect, a link may be coupled to a support with a flexible blade.

Body support structure

A body support assembly includes a seat assembly and backrest assembly supported by a tilt control assembly. Methods of using and assembling the body support assembly are provided.

A seating arrangement including a seat member, a base, and an arm assembly including an arm base having a central portion and a receiver portion and exclusively supported from the base via a central portion at a position located between lateral outermost edges of the seat member, an arm stalk telescopingly received within the receiver portion and movable between retracted and extended positions, an arm support supported by the arm stalk, where the arm support moves in a forward direction with respect to the seat member as the arm stalk is moved from the retracted position to the extended position, and a bearing arrangement positioned between the arm stalk and the receiver portion and including a bearing member located between the receiver portion of the arm base and the arm stalk and a biasing member configured to bias the bearing.

Seating arrangement

A seating structure includes a shell having a central portion, opposite outer peripheral edges laterally spaced from opposite sides of the central portion, and at least one biasing array disposed between each of the opposite sides of the central portion and a respective outer peripheral edge. Each of the biasing arrays includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The biasing array may include a plurality of biasing arrays, with at least one connector connecting adjacent biasing arrays. A second shell may be connected to the outer peripheral edges of the first shell, with an open space defined there between. Each of the opposite outer peripheral edges is independently deflectable in response to a load being applied to the second shell.

Compliant seating structure

A workspace assembly includes at least a first sound sensor located in a first facility space, at least one communication device located within the first space, and a processor in communication with the at least a first sound sensor and the communication device. The processor is adapted to compare the volume of sound emanating from within the first space to a threshold level and to generate a signal via the communication device when the volume of sound emanating from within the first space exceeds the threshold level. The processor also periodically automatically adjusts the threshold level.

Sound detection and alert system for a workspace

A backrest includes a primary frame having a pair of laterally spaced first uprights defining a first opening therebetween, a first front surface and a first rear surface. A secondary frame includes a pair of laterally spaced second uprights defining a second opening therebetween, a second rear surface facing the first front surface of the primary frame and a second front surface, wherein the secondary frame is coupled to the primary frame, and wherein at least portions of the first and second openings are aligned. A flexible shell overlies and is coupled to the second front surface of the secondary frame. The flexible shell includes a third rear surface visible through the aligned portions of the first and second openings.

Compliant backrest

A seating arrangement includes a support shell including a seat portion and a chair back portion each configured to support a seated user, the chair seat portion having a front region and a rear region and the chair back portion having an upper region and a lower region, where the rear region of the seat portion is coupled to the lower region of the chair back portion, a control member including a substantially flexible front support and an attachment point, where the front support engages the support shell in the front region of the seat portion and the control member engages the back portion, and a substantially rigid second support attached to the control member at the attachment point, wherein the control member is an integral, one-piece component including multiple flex regions configured to allow the support shell to move between an upright and reclined position.

A seating arrangement includes a base member, and an integrally formed support member coupled to the base member and supporting a seat moveable from an upright position to a reclined position, wherein a portion of the support member is bendable as the seat moves from the upright position to the reclined position such that a first side of the support member is put in tension and a second side generally opposite the first side is put in compression, and wherein the first side includes a tensile substrate so that the first side has as higher modulus of elasticity than the second side.
