    摘要： 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.

    摘要： 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. 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.

    摘要： A structural support shell for a tilt-back chair has a back portion, a seat portion, and a flexible compression zone extending between the back and seat portions in an integrally molded, one-piece unit. The chair has a base with a recline control pivoting recline control lever. The seat portion of the shell is fixed to the base and the back portion of the shell is fixed to the recline control lever. The flexible compression zone provides a simplified construction for an ergonomic chair design having an effective axis of rotation between the back portion and seat portion which is located above the seat portion, forward of the back portion, and generally adjacent to the hip joints of a seated user. The chair includes side arms that laterally and then rotatably engage side arm supporting connectors on the chair to facilitate assembly. The chair further includes a one-piece shell having tabs for mateably engaging flanges on the chair seat and back to also facilitate assembly.
