Abstract: A chair with a back arrangement employing a back shell slidably supported on a pair of uprights projecting upwardly from opposite sides of the chair seat. The chair includes manually releasable latching mechanisms which cooperate with the uprights to allow height adjustment of the back arrangement. The chair additionally incorporates an adjustment mechanism which allows manual adjustment of the chair arms into the desired position.

Abstract: A back pad for a chair having a back defined by a shell, the back pad being fitted over the back shell and providing the back with a resilient padded feel while additionally providing styling flexibility with respect to the appearance of the chair back.

Abstract: An improved chair having a simplified height-adjustable back arrangement. The back arrangement is defined principally by a back shell provided with support sleeves adjacent opposite sides thereof. The support sleeves are slidably supported on respective uprights which project upwardly adjacent opposite sides of the chair seat. A manually-releasable latching mechanism cooperates between each support sleeve and its respective upright whereby a seated occupant, by using right and left hands, can simultaneously release both latching mechanisms and effect vertical slidable displacement of the back shell to adjust the position thereof.

Abstract: A chair having a swingable chair back with a top pivot includes a frame having laterally spaced first and second uprights. A back having upper and lower ends is attached to the frame. Also attached to the frame adjacent the lower end of the back is a seat. A pivot assembly couples the first and second uprights to the back and permits pivoting of the back about a substantially horizontal pivot axis. The pivot axis projects laterally of the back and is positioned in the vicinity of the upper end of the back. A biasing device cooperates with the back and normally urges the lower portion of the back forwardly away from a rearward position.

Abstract: A chair having adjustable height arms includes a rigid chair frame having first and second uprights. A back is attached to the chair frame and includes upper and lower ends. A seat is also attached to the chair frame and is adjacent the lower end of the back. Cantilevered to each of the first and second uprights is an arm assembly that projects outwardly therefrom adjacent opposite sides of the seat. Each arm assembly includes a coupling structure that is releasably engaged with a respective upright and is configured to release from the upright when the arm assembly is tilted upward relative to the respective upright to permit the elevational position of the arm assembly to be adjusted.
