Patent number: 6786548Abstract: 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.Type: GrantFiled: September 26, 2002Date of Patent: September 7, 2004Assignee: Steelcase Development CorporationInventors: Peter J.
