Abstract: A seat portion (14) for a seat (10) wherein the seat portion (14) includes a panel having a rear portion to support the occupant. The rear portion has a longitudinal centerline and incorporates two zones (162) on either side of the longitudinal centerline. Each of the zones has a first pattern of weakeners arranged in a series of spaced sinuous lines. Furthermore, a substantial portion of the panel, apart from the zones (162) may also be provided with a pattern of weakeners arranged in a series of spaced sinuous lines (163), interrupted by the zones (162).

Abstract: A chair (10) includes a supporting frame (20,22) and a seat portion (14) which is foldable about a transverse fold to define a rearward portion behind the transverse fold and a forward portion, forward of the transverse fold. The seat portion (14) is supported above the supporting frame by its rearward portion. The chair (10) also includes a reclinable back portion (16) and a recline mechanism with which the back portion (16) is connected for reclining action of the back portion (16). The recline mechanism is operably linked to the rearward portion of the seat portion (14) such that on reclining action of the back portion (16), the rearward portion is moved to increase in rearward tilt angle and to obtain a net increase in height above the supporting frame (20,22), with a consequent folding of the seat portion about the transverse fold line under the weight (W) of the occupant.

Abstract: A castored base (18) for an office chair includes a plurality of radially extending legs (300), each leg having a socket or sleeve (308) fixed thereto adjacent an outer end thereof. A castor (302/402) is connected to each socket or sleeve (308), each castor having two wheel portions (312/412) and an axle assembly (316/404). The axle assembly includes an axle (314/414) to which the two wheel portions are rotatably mounted in spaced disposition and including a pin (318/418), wherein the pin (318/418) of each castor is received in a respective socket or sleeve (308) which extends at least in part between the two wheel portions (312/412). Only a small clearance is required between the underside of the legs (300) and the tops of the castors (302/402). Further, low profile legs (300) may be used in the base (18), while still providing the required strength and stability.

Abstract: A back portion (16) for a chair (10) includes a peripheral frame (34) defining an opening therein. A lumbar support portion (36) is disposed in the opening. The lumbar support portion (36) comprises a substantially rigid panel (207). Two hinge devices (214) are hingedly mounted on opposite sides of the peripheral frame (34). The lumbar support portion (207) is mounted on the peripheral frame by the two hinge devices (214). Each hinge device has a biasing device (226) associated with it to bias the hinge devices (214) forwardly relative to the peripheral frame (34). A cushion (540) may be mounted atop the lumbar support portion (207). The cushion has a first substantially planar sheet (542) of resiliently flexible material and a second substantially planar sheet (544) of resiliently flexible material. The first and second sheets are separated by a plurality of spaced webs (546) of resiliently flexible material.

Abstract: An arm assembly (24) is provided for a chair (12). The chair (12) has a forward direction and a rearward direction. The arm assembly (24) includes an armrest (26) and a support structure (28). A mounting device movably mounts the armrest to the support structure. The mounting device constrains the movement of the armrest (26) relative to the support structure to movement in a substantially horizontal plane having two degrees of freedom defined by first and second transversely arranged axes lying within the substantially horizontal plane. The armrest (26) thus move in a substantially planar fashion without changing the orientation of the armrest (26).

Abstract: A work station support comprises two mounting brackets arranged in use to be attached to a work station top at a spaced relationship. Each mounting bracket has a fixing plate and an arm extending from said fixing plate. Two separate key hole slots are formed on each fixing plate at a locus about a center of rotation of the fixing plate. The key hole slots are formed to engage studs projecting from the table top when the fixing plates are rotated in opposite directions. A post upwardly extends from each mounting bracket. Outwardly projecting from the top end of each post is an arm. A shelf is supported on and extends between the arms. A rail also extends between the posts and functions as a back stop for the shelf. A retainer is slidably mounted on the rail and partially extends across the shelf.

Abstract: A work station support comprises two mounting brackets (4) arranged in use to be attached to a work station top (1) at a spaced relationship. Each mounting bracket (4) has a fixing plate (5) and an arm (6) extending from said fixing plate (5), two separate key hole slots (11, 12) formed in said fixing plate (5) at a locus about a center of rotation of said fixing plate (5). The wider part (13) of each key hole slot is adapted to engage over the head of a mounting stud (17) in use and upon rotation of the fixing plate (5), the stud is moved to the narrower part (14) of each key hole slot (11, 12). The said key hole slots (11, 12) are formed to require the fixing plates (5) to be rotated in opposite directions to move to the engaged position.

Abstract: A cable support has a cable holding portion and a mounting portion with one or more teeth. The mounting portion and the one or more teeth are shaped for insertion into a groove formed in an item of furniture. The cable support is rotatable about an axis and the one or more teeth are shaped for penetration with one or both of the side walls of the groove. A method of supporting cables from an item of furniture is also claimed.

Abstract: A copy holder is provided with a document holding stand supported adjustably by a support structure to provide a stable support while allowing operator controlled, incremental adjustment through a working range to vary the angle at which the document holding stand is supported. The adjustable support structure is provided by spring clutches on either end of a shaft which can be releasably held in housings attached to the document holding stand and these points of attachment together with a back leg provide for stable support with the incremental adjustment effected by releasing the spring clutch to adjust the gripping position on the shaft relative to the point of attachment for the back leg.

Abstract: A roller assembly (12) for a screening assembly (10) includes a non-linear axle (30) and a flexible sleeve assembly (32) rotatable about the axle (30). A table assembly (40) includes a table surface (42) which is adjustable in height over a range of height positions and a screen (14) extendable below the table surface (42). The screen (14) is adjustable with the height adjustment of the table surface (42). A modesty screen (10) for a height adjustable table (40) has first and second relatively movable portions (44,46). The modesty screen (10) includes a screen (14) and a retraction unit (16) such that the screen (14) may be retracted and extended. The retracting unit (16) is adapted for attachment to the first portion (44) of the table (40) and the screen (14) is adapted for attachment to the second portion (46) of the table (40).
