  • Patent number: 6786548
    Abstract: A synchrotilt chair includes a base, a back, a seat, and a link(s) pivoted to a rear of the base and to a bottom of the back to form a four-bar linkage arrangement. In one form, the chairs are nestable and stackable for dense storage. In another form, the chairs are desk-type pedestal chairs. Several of the structural support members of the chair are gas-assisted injection molding to form a hollow tubular perimeter frame that is lightweight, strong, and dimensionally-accurate A flexible panel is integrally molded between opposing sides of the perimeter frame. Armrests are pivoted to the back and have a shape configured to allow nested stacking while also providing excellent comfort, durability, and style. Also, the armrests are movable to remote storage positions to provide unobstructed side access to the seat of the chair.

  • Patent number: 6536841
    Abstract: A synchrotilt chair includes a base, a back, a seat, and a link(s) pivoted to a rear of the base and to a bottom of the back to form a four-bar linkage arrangement. A spring arrangement includes a resilient member at one of the joints of each link to bias the link and in turn the back and seat toward an upright position, with the back and seat pivoting with a synchronous motion upon recline of the back. In one form, the chairs are nestable and stackable for dense storage. In another form, the chairs are desk-type pedestal chairs. Several of the structural support members of the chair are gas-assisted injection molding to form a hollow tubular shape that is lightweight, strong, and dimensionally-accurate.

  • Patent number: 6099076
    Abstract: A chair includes a base, a seat operably supported on the base for depth adjustment, and a back operably supported by an upright that extends from the base for recline. The back includes a structural back support, a rear cover covering a rear side of the back support, and a front/lower concave cover covering the upright between a rear of the seat and below the back support to provide a one-piece back and seat appearance. The concave cover defines a concavity shaped to receive a rear of the seat to facilitate depth adjustment, but so that the one-piece back and seat appearance is maintained. The concave cover further includes upwardly extending tabs that engage a lower marginal edge of the back support to facilitate assembly.
