  • Patent number: 9901176
    Abstract: A chair has a supporting frame 1, a seat portion 101, a back portion 201 that has an upper end, a lower end, and is pivotally mounted relative to the supporting frame at a position above its lower end, and a recline mechanism 601. The recline mechanism 601 lifts the seat portion 101 upon a reclining action of the back portion 201, and has an operative connection 603, 611 between the seat portion and the supporting frame and a drag link 602 pivotally connected to the seat portion 101 and pivotally connected to the back portion 201 at a position below the pivotal mounting of the back portion relative to the supporting frame. As the back portion 201 of the chair is reclined, the lower end of the back portion 201 moves forward and the drag link 602 pulls the seat portion 101 upward relative to the supporting frame 1.

  • Patent number: 9622579
    Abstract: A chair has a seat support, a seat portion, a back portion, and a supporting frame. The supporting frame is formed by a castored base, a height adjustment mechanism, and a main transom. The seat portion is selectively moveable relative to the supporting frame, with the seat portion having a locked configuration and a released configuration. The back portion has a back frame and a compliant cover. The back frame has hood features for receiving a portion of the compliant cover. The back portion is reclinable relative to the supporting frame between an upright position and a reclined position. A recline mechanism has deformable members operatively connecting the seat portion and the supporting frame. A recline resistance mechanism is selectively engageable to resist movement of the back portion toward the reclined position.

  • Patent number: 9003635
    Abstract: A method of injection molding a polymeric resin to form an article that is suitable for strain orientation. A thermoplastic polyester elastomer polymeric resin is provided. The resin is heated to form a molten resin at a temperature of at least about 240° C. The molten resin is injected into a mold (22) to substantially fill the mold and form an article. At least part of the article is a sheet part with a plurality of members that are integrally formed into the sheet part, with apertures provided between at least some of the members of the sheet part of the article to form a mesh. At least the sheet part of the article is suitable for strain orientation.

  • Patent number: 8888183
    Abstract: A chair has a supporting frame, a seat portion for supporting an occupant, and a back portion for supporting the back of a seated occupant. The portion is reclinable relative to the supporting frame between a generally upright position and a generally reclined position. A preference control is operatively engaged between the back portion and a chair component, wherein displacement of the back portion toward the generally reclined position causes displacement of the chair component. The preference control is adjustable to vary the amount of displacement of the chair component caused by a given amount of displacement of the back portion toward the generally reclined position.

  • Patent number: 8668265
    Abstract: A chair has a supporting frame, a seat portion, a back portion, and a recline mechanism. The mechanism moves the seat portion upon a reclining action of the back portion. The mechanism has a rear deformable member and a front deformable member operatively connecting the seat portion and the supporting frame. The recline mechanism also has a lower deformable member operatively connecting a lower part of the back portion and the supporting frame, and a puller member above the lower deformable member. The recline mechanism is configured such that as the back portion is reclined, the lower deformable member deforms and the puller member applies a rearward pulling action which causes the seat portion to move and the front and rear deformable members to deform.

  • Patent number: 8613481
    Abstract: A back portion for a chair has a back frame, the back frame having a lower portion adapted to extend across at least a major part of a lower region of a seated adult occupant's back, an upper portion vertically spaced from the lower portion and adapted to extend across at least a major part of an upper region of the occupant's back, and a relatively narrow interconnecting region between the upper portion and lower portion. The relatively narrow interconnecting region is resiliently flexible to provide a flexing movement in a rearward direction of the upper portion relative to the lower portion. A cover operatively connected to the back frame provides a supporting surface for the back of the seated occupant.
