Abstract: A chair back is disclosed and includes a mesh material connected to a two-piece carrier, the carrier being deformable and stretchable. The carrier has a bottom edge including a groove and is engageable by tabs attached to a transverse member of a chair frame assembly. The upper ends of the carrier each includes an opening for receiving a spherical end portion of the upper end of the chair frame assembly. Engagement of the carrier with the chair frame assembly is accomplished by stretching the carrier and mesh between the transverse member and the spherical end portions. The chair back includes a lumbar support which is mounted to slide along the side edges of the carrier and along vertical supports of the chair frame assembly, the lumbar support causing the chair to tension forwardly. The chair back is pivotal under the influence of a chair user and is pivotally connected to the chair seat so as to cause the chair seat to also pivot in response.

A first side platform is affixed to the first support shaft. A second side platform is affixed to the second support shaft. A front platform is positioned in front of the chair. The front platform may be rotated away from the front of the chair by a pivot system which assists in moving the front platform. The system may also include two accessory platforms mounted adjacent each side platform. All the platforms may be adjustably positioned for the occupant of the chair. Computer and gaming control devices may be placed on top of the platforms.

Abstract: A seat connection mechanism having a saddle bracket portion and a pin portion is provided. The saddle bracket portion includes an inner pivot channel, an occupied position stop, an unoccupied position stop, and an outer surface which extends between the occupied and the unoccupied position stops. The pin portion includes a pivot pin and a stop pin protruding therefrom. The pivot and stop pins are positioned such that, and are spaced apart by a distance such that, when the pin portion is angled with respect to the saddle bracket portion at an insertion angle, the stop pin is positionable adjacent to the outer surface and the pivot pin is insertable into the inner pivot channel, and such that when the pin portion is angled with respect to the saddle bracket portion at an angle other than the insertion angle, the pivot pin is retained in the inner pivot channel.

Abstract: A chair includes a base having an adjustable column, a seat, and a back. An underseat assembly operably supports the seat and the back on the base. The underseat assembly includes a metal bottom support with a tapered socket shaped to engage the column, and includes a seat-supporting yoke constructed with a center section shaped to vertically engage the bottom support. Opposing side support sections include inwardly facing mounting sections that mateably engage a top of the center section. A retainer plate clamps the bottom support, yoke, and side support sections together. A link is operably attached to the side support sections and the back for supporting the back. The seat, the back, and underseat components are constructed for top down assembly without requiring that the chair be inverted during assembly, and they form a four-bar linkage with the link that supports synchronous movement of the seat and back.

Abstract: An object of the present invention is to minimize the dependency of the vibration characteristic exhibited by the sheet-shaped supporting member supported by the metal springs on the added load. In a plurality of metal springs 41 to 44 supporting a sheet-shaped supporting member 30, a third metal spring 43 provided on the position to support the vicinity of the greater trochanter of the seated person is provided in a manner that an engagement portion with a frame member is positioned lower than the engagement portion with the sheet-shaped supporting member 30 when no load is applied. Accordingly, the feeling of something foreign created by such a third metal spring 43 can be reduced, and within a predetermined range of the added load, the third metal spring does not work functionally because respective engagement portions 43a and 43b take their positional relationship to be substantially horizontal in a static seating state, while it works functionally when the added load exceeds the above-described range.

Abstract: Pull rod-type foldable chair structure. A pull rod is telescopically inserted in the top end of the rear chair leg and pivotally connected with the front chair leg. When folding or unfolding the rear chair leg, the pull rod provides a pneumatic buffing effect. Two J-shaped lateral support boards are previously mounted on inner sides of the chair frame, whereby the seat can be directly assembled with the support boards by insertion. The back is assembled with the upper end of the front chair leg by engaging members. Therefore, the chair frame, the seat and the back can be quickly assembled. The transverse beam of the chair leg is equipped with elastic ground-contacting blocks. Therefore, the chair can be used on any floorboard made of any material such as wooden, plastic and stone floorboards. The ground-contacting block will not scrape the floorboard and the chair can be more stably placed on the ground.

Abstract: A synchrotilt mechanism for a chair to provide improved control over the relative but synchronized tilting of the back and seat during tilting. The chair back is supported on a rigid upright assembly including lower lever arms which project under the chair seat and are coupled at forward ends to a horizontal tilt shaft which is disposed under the front of the chair seat and is supported on a control housing fixed to the upper end of the base pedestal. A tension control mechanism is coupled between the tilt shaft and the control housing for normally urging the upright arrangement, and the chair back, into an upright position. The chair seat is movably supported on the lower lever arms by a support arrangement which permits the chair seat to pivot relative to the upright assembly about a generally transverse horizontal axis which is preferably slightly below the upper surface of the seat when the latter is in a nondeformed condition, i.e., the seat is not occupied.
