Abstract: A pivoting mechanism with gross and fine adjustment with a housing, an elongate shaft pivotally retained by the housing, resiliently deformable members retained by the housing, cam members coupled to the shaft wherein the cam members are disposed to deform the resiliently deformable members when the cam members are pivoted, and a locking slide bar for selectively causing the cam members to pivot with the shaft to produce gross adjustments in pivoting resistance. First and second ends of the shaft can act as an output interface for outputting the pivoting resistance exhibited by the shaft to a seat back structure, a seat bottom structure, or some other structure. A threaded rod rotated by a handle can adjust an initial deformation of the first resiliently deformable member for fine pivoting resistance adjustment.

Abstract: A mobile task chair with a mobile base structure, a control mechanism, a seat bottom, and a seat back. A physical setting control mechanism is adjustable to control a physical setting of the mobile task chair, and a visual indicator provides a visual indication, such as an illuminated visual indication, of the physical setting of the mobile task chair as adjusted by the physical setting control mechanism. The physical setting control mechanism can be pivoting resistance adjustment mechanism, and the visual indicator can indicate a selected pivoting resistance based on a resistance sensed by a resistance sensor. Multiple physical setting control mechanisms and a corresponding multiplicity of separate visual indicators can be provided. The visual indicator can be selectively induced as by touch and can be effective for a given time period. Recommended settings can be provided and automatically or selectively induced.

Abstract: The synchronizing device comprises a seat carrier for carrying a seat of said office chair, a seat arm to be connected to a chair column of said office chair, said seat carrier being pivotable in relation to said seat arm about a transverse axis, a backrest arm connected to said seat arm and to said seat carrier such as to be pivotable about a transverse axis, a spring adapted to counter a synchronized movement of said seat carrier and backrest arm, and a sliding member extending substantially in a longitudinal direction of said seat and being articulated to said seat arm, said seat carrier being slidable in relation to said sliding member substantially in said longitudinal direction of said seat.

Abstract: An improved knockdown chair having opposing substantially C shaped support arms, substantially L shaped tubular seating arrangement, sock type seating portion cover, front reinforcing member, and bottom reinforcing member, wherein each of the opposing substantially C shaped support arms are of laminate construction and have an upper arcuate arm support, front arcuate portion, and substantially straight bottom, the substantially L shaped tubular seating arrangement having a tubular seat back and tubular sitting portion telescopically interconnected one to the other, and wherein each of the opposing substantially C shaped support arms is opposingly removably fastened to the substantially L shaped tubular seating arrangement, the improvement comprising combination with each of the opposing substantially C shaped support arms of a substantially S shaped reinforcing member of laminate construction removably fastened to the upper arcuate arm support and the substantially straight bottom for reinforcing each of the

Abstract: An angle-adjusting structure for a backrest of a chair is mounted at a rear side of a butterfly-shaped mounting member of the chair. The angle-adjusting structure includes a main body and a rotating member jointly passed through by a shaft having external teeth. A resilient element is mounted around an end of the shaft. A cover is secured to the main body by threaded fasteners. A pressing member is mounted on the other end of the shaft. By pressing the pressing member inward, the external teeth of the shaft are disengaged from internal teeth of the rotating member, and the rotating member is allowed to rotate freely. When the pressing member is released, the resilient element mounted around the end of the shaft extends outward to re-engage the external teeth of the shaft with the internal teeth of the rotating member, thereby securing the rotating member in place.

Abstract: A backpost for use in wooden dining chair. The backpost unit provides reclining movements for a wooden chair of the type having a stationary frame section within which the backpost unit is secured. The backpost unit consists of an interlocking mechanism with minimum components and requires minimum maintenance and provides a solid and reliable reclining mechanism. The chair enables the user to secure an accurate posture of sitting during eating and also enables the user to enjoy a relaxing posture while sitting on the same dining chair.

Abstract: Cushioning device to cushion a backrest with respect to the seat of a chair or suchlike. The device comprises a first supporting element connected to the backrest, a second supporting element connected to the seat and pinned to the first supporting element, and a spring connected both to the first supporting element and to the second supporting element, to allow a reciprocal elastic oscillation, of a determined amplitude, between the backrest, which can oscillate, and the seat, which remain still. In a wall of the first supporting element a lodging seat is provided to lodge, at least partially, the spring in such a manner that the longitudinal axis of the spring is substantially aligned with respect to the first supporting element.

Abstract: A chair including a frame, a seat pivotally mounted on the frame, a spring construction effectively positioned between the seat and the frame, a first selectively actuatable latch positioned between the seat and the frame effective to maintain the seat latched in a less inclined position on the frame, a second selectively actuatable latch positioned between the seat and the frame effective to maintain the seat latched in a more inclined position on the frame against the bias of the spring construction, a foot rest pivotally mounted on the frame and movable between retracted and extended positions, and a cable secured to the foot rest for selectively retracting the foot rest to the retracted position.

Abstract: A tilt back chair provides for selective independent and concurrent movement of a chair back with respect to a chair seat. The seat is mounted to a spring biased bracket for pivotal movement about a seat tilt axis. The back is connected to a pair of pivot brackets projecting upwardly from the seat to provide for pivotal movement about a back tilt axis located above the seat and rearwardly of the seat tilt axis. When the seat is in a neutral seating position it can tilt downwardly at its forward edge about the seat tilt axis. The back is biased for displacement with the forward tilt of the seat and is tiltable rearwardly independently of the seat. The seat can also be locked in a fixed position.
