Abstract: A J-back calibration device is adapted to vary respective positions of the seat and the back on a chair to which it is removedly attached. A chair measurement device is mounted to the seat of the chair and is adapted to take measurements of the chair given a set position of the J-back calibration device. A design of experiments software is provided with test condition information including the variable positions of the J-back calibration device and measurements from the chair measurement device. The software generates a table of configuration settings for the J-back calibration device at which shirt-pull and bridging or other such variable sought to be optimized can be measured and provided to the software. Through graphical and other analytical tools, optimal configuration settings for the variable positions of the J-back calibration device are determined. The J-back of a chair is adapted to these calibrated settings.

Abstract: A chair control mechanism is provided for use on a chair having a separate seat 14 and backrest 16 that move with respect to a base 12 of the chair. The mechanism 22 includes a housing 26 supported on the base, and brackets 28, 30 secured to the seat and backrest. The seat bracket 28 is supported on the housing for pivotal movement about a horizontally extending front pivot axis 68 between an upright position and a reclining position, and the front pivot axis is located adjacent the front end of the housing. The backrest bracket 30 is supported on the housing for pivotal movement about a horizontally extending rear pivot axis 80 that is located rearward of the front pivot axis.

Abstract: In a chair having a base, a seat, a backrest, and a tilt control mechanism, a horizontal adjustment mechanism is provided for allowing fore and aft shifting movement of the seat relative to the backrest. The tilt control mechanism typically includes a pair of rails or other mounting structure by which the control mechanism is normally fastened to the seat. The rails present a pair of laterally spaced longitudinally extending edges and a plurality of mounting holes arranged in a predetermined pattern. The horizontal adjustment mechanism includes a seat mounting assembly provided with a pair of laterally spaced guides adapted to engage the edges of the rails to support the seat mounting assembly for sliding movement on the control mechanism.

Abstract: An adaptor housing assembly for mounting an adjustable height work surface to a wall panel of an open office furniture system. The wall panel has a pair of vertical slotted standards which are adapted to receive the hooks of a mounting bracket. The adaptor housing assembly mounts a height adjustable work surface to the vertical slotted standards of the wall panel by clamping a mounting bracket to an adaptor housing in which is mounted a height adjustment mechanism having a frame which is connected to the work surface. The adaptor housing is fixed with respect to the wall panel and the frame of the height adjustment mechanism moves vertically with respect to the wall panel to raise and lower the work surface. The channel guides the moving members of the mechanism to which the work surface is mounted. The adaptor housing has a pair of elongated flanges extending outwardly from one end of the adaptor housing to form a slot which receives an elongated plate having tapped holes.

Abstract: The invention is a crank which is flush-mounted into a work surface and provides for raising or lowering a vertically adjustable work surface. The crank can be raised from its stored position to a fixed position above the work surface and unfolded providing for rotating the crank to raise or lower the work surface by causing an adjustment screw to thread in or out of an adjustment nut. The crank is returned to its stored position or flush-mounted by folding the crank and pressing downward.

Abstract: Modular wall panels and ancillary furnishings and fixtures, such as shelves and cabinets, having a single load-bearing connector post between two coplanar panel members. The panel members engage apertures in the side walls of the connector post. The front and back walls of the connector post are vertically slotted with a width dimension to support hooks from two brackets within each slot, one from the left and one from the right sides of adjacent shelves, desk surfaces or cabinets. Thus, the connector posts directly support all of the system load without lateral force transfer from intermediate load bearing members. The load is transmitted vertically downward to a support surface, usually a floor. At intersections of non coplanar panels, a connector post terminates each planar panel run and is joined to a non load-bearing intersection post at a side wall of each connector post.

Abstract: The specification discloses a chair including side arms readily and conveniently alignable with one another and/or the chair seat at any time, even after the chair is assembled. More specifically, the control includes a chair iron and a pair of side arms pivotally supported by the iron on opposite sides thereof for movement in a generally vertical plane. Further included is a locking mechanism for releasably locking each arm in one of its pivotal positions to fixedly secure the arms in alignment with respect to the chair iron.

Abstract: The specification discloses a modular merchandising display system including a plurality of upright members, a plurality of lateral members interconnecting the upright members, and a plurality of decor strips releasably mounted on and encapsulating each upright member. Each decor strip includes two flexible sides, each of which is adjacent an edge of another decor strip on the upright member so that the upright members are hidden. The lateral members extend between adjacent sides, which flex to accommodate the lateral member.

Abstract: A chair of the type used in theaters or the like includes a seat mounted to a standard by pivot mechanisms which bias the seat to a three-quarter fold position in which the seat is raised to permit row egress. The chair back is pivotally mounted for rotation about a horizontal axis located in the back area of an occupant. A link connects the specially formed seat frame to the lower part of the back frame so that when the seat is in the three-quarter fold position, the top of the chair back is rotated forward so that the chair back assumes a generally vertical disposition thereby increasing egress room for the occupant of the row to the rear. Also, in the three-quarter fold position the link/frame mechanism locks the back panel in that position so that it cannot be displaced should an occupant of the next row to the rear grasp the back panel and use it to steady himself or pull himself out of his seat.

Abstract: Seating for a telescoping row system or the like includes a chair back and seat mounted to a frame which automatically raises and lowers as the rows are opened and closed respectively. A pair of hinge mechanisms are clamped to the frame at the side of each chair for mounting the seats and backs while permitting them to rotate about a common axis which extends along the intersection of the hip and lumbar region of the occupant. The hinge mechanisms include one spring which normally biases the seat of the chair to the three-quarters fold position when it is unoccupied, but permits it to be lowered for an occupant or moved to the fully raised position for passing. In one embodiment, a second spring biases the back of each chair to the use position when the chair is raised. When the chair is folded for storage, the back and seat are rotated toward each other to a fully closed position.
