An adjusting assembly for mounting a supporting tray assembly to a chair using one or more arm assemblies. The proximal end portion of a mounting bar is secured to a chair such that the mounting bar is disposed substantially horizontally. A substantially vertically disposed support assembly is mounted from the distal end portion of the mounting bar, and the support assembly may be rotatable about a vertical axis, if desired, to facilitate entering and exiting the chair. If only one arm assembly is used, the first end portion of an arm assembly is supported for articulation from the pivot assembly, and a tray assembly is pivotally supported from the second end portion of the arm assembly. If two or more arm assemblies are utilized, each arm assembly has a housing with first and second end portions. One end portion of one arm assembly is supported from a chair for articulation about a first articulating axis, and a tray assembly is pivotally supported from one end portion of another arm assembly for movement about a pivotal axis. The other end portions of the arm assemblies are interconnected for relative articulation about one or more intermediate axes. Locking means operatively interact with the arm assemblies to secure: (1) the selected position of the articulating arm assemblies about the first articulating axis, (2) the selected pivotal position of the tray assembly about its pivotal axis; and, (3) the selected articulation of the arm assemblies with respect to each other about the intermediate articulating axes.

Adjusting mechanism for a chair-mounted computer input device

An adjusting device embodying the concepts of the present invention is incorporated in a mount by which a tray assembly adapted to support an input device for a computer is supported from a chair. The proximal end portion of a mounting bar is supported from a chair such that the mounting bar is disposed substantially horizontally from the chair. A substantially vertically disposed support assembly is rotatable mounted from the distal end portion of the mounting bar. The first end portion of an arm assembly is supported for articulation from the pivot assembly about an articulating axis that is disposed substantially horizontally. A tray assembly is pivotally supported from the second end portion of the arm assembly about an pivotal axis that is disposed substantially horizontally. Means may be provided selectively to establish the distance between the mounting bar and the articulating axis. Locking means may also be provided selectively to secure the pivotal position of the tray assembly with respect to the arm assembly, the articulated position of the arm assembly with respect to the support assembly and to establish the distance between the mounting bar and the articulating axis.

Combined chair and tray

A suspension mechanism (10, 310, 410, 510 and 610) utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12, 312,412, 512 or 612) to a pedestal assembly (14). A support (30, 430, or 530) is fastened to the upper end portion of the pedestal assembly (14). A connector, in the form of a primary seat spring (40), or a rigid, connecting plate (513), is secured to the support (30, 430 or 530) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). An interactive spring (60 or 660) may also be secured to the support (30, 430 or 530). The interactive spring (60 or 660) extends outwardly from the support (30, 430 or 530) in generally parallel relation with the connector (40 or 513) to be disposed in a cantilevered fashion therebetween. The back supporting portion (18) may include a back cushion assembly (102) that is structurally carried by a stanchion (90, 390, 490 or 690) that may be fixedly, or pivotally, secured to the seating assembly (16). When the stanchion (90, 390, 590 or 690) is pivotally mounted, a follower (130) may be presented from the stanchion (90, 390, 590 or 690) operatively to engage the interactive spring (60 or 660). A main back spring (140) may also be secured to the stanchion (90 or 590) to interact against the undersurface (146) on the seating pan (72) of the seating portion (16). One or more lock-out assemblies (150) may be utilized to effect immobilization of the back supporting portion (18) with the seating portion (16) and/or the seating portion (16) with respect to the pedestal assembly (14) if those components are not permanently affixed to each other or are not manually adjustable with respect to each other.

Suspension mechanism for connecting chair backs and seats to a pedestal

A suspension mechanism (10, 310, 410, 510 and 610) is utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12, 312, 412, 512 or 612) to a pedestal assembly (14). A support (30, 430 or 530) is fastened to the upper end portion of the pedestal assembly (14). A connecting element in the form of a primary seat spring (40), or a rigid, connecting plate (513), is secured to the support (30, 430, or 530) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). An interactive spring (60 or 660) may be secured to the support (30, 430, or 530). The interactive spring (60, or 660) extends outwardly from the support means (30, 430 or 530) in generally parallel relation with the connecting means (40 or 513) to be disposed in a cantilevered fashion therebetween. The back supporting portion (18) may include a back cushion assembly (102) that is structurally carried by a stanchion (90, 390, 490, 490 or 690) that may be fixedly, or pivotally, secured to the seating assembly (16). When the stanchion (90, 390, 590 or 690) is pivotally mounted, a follower (130) may be presented from the stanchion (90, 390, 590 or 690) operatively to engage the interactive spring (60 or 660). A main back spring (140) may also be secured to the stanchion (90 or 590) to interact against the undersurface (146) on the seating pan (72) of the seating portion (16). One or more lock-out assemblies (150) may be utilized to effect immobilization of the back supporting portion (18) with the seating portion (16) and/or the seating portion (16) with respect to the pedestal assembly (14) if those components are not permanently affixed to each other or are not manually adjustable with respect to each other.

The present invention is directed to a suspension mechanism (10) utilized to interconnect the seating portion (16) as well as the back supporting portion (18) of a chair assembly (12) to a pedestal assembly (14). A spring support (30) is fastened to the upper end portion of the pedestal assembly (14). At least one primary seat spring (40) is secured to the spring support (30) and extends generally upwardly and rearwardly therefrom to be secured to the underside of a seating portion (16). Preferably, the primary seat spring (40) comprises a pair of laterally spaced, leaf springs (40). Also secured to the spring support (30), and preferably between the pair of laterally spaced primary seat springs (40), is an interactive spring (60). The interactive spring (60) extends outwardly from the spring support (30) in generally parallel relation with the primary seat springs (40) to be disposed in a cantilevered fashion therebetween. The back supporting portion (18) includes a back cushion assembly (102) that is structurally carried by a stanchion (90) that is pivotally secured to the seating assembly (16). A follower (130) is presented from the stanchion (90) operatively to engage the interactive spring (60). The main back spring (140) is secured to the stanchion (90) to interact against the undersurface (146) of the seating portion (16). One or more lock-out assemblies (150) may be utilized to effect immobilization of the back supporting portion (18) with the seating portion (16) and/or the seating portion (16) with respect to the pedestal assembly (14).

A seating device (10) capable of dissipating an electrostatic charge received thereby, the seating device (10) having a frame (11) defining an electrical ground. A rigid supportive substrate (24) is fixedly secured to the frame (11). A cushion (32) is carried by the supportive substrate (24) and an electrically conductive mesh (33) is carried over the cushion (32) and secured to the supportive substrate (24). An electrically nonconductive cover (40) is carried over the mesh (33) and is, likewise, secured to the supportive substrate (24). Means (42) are provided to electrically communicate the mesh (33) with the frame (11).
