  • Patent number: 6820934
    Abstract: A chair comprises a seat support assembly including a seat support, the seat support assembly being adapted to stand on a surface so as to provide the seat support at a suitable height for a person to sit on, and a back support assembly, including a back frame member and a back support. In one embodiment, the back frame member has a curved middle portion substantially in the plane of the back support, and first and second end portions substantially in the plane of the seat support. The back frame member is flexibly interconnected to the seat support assembly by a first spring flexibly interconnecting the first end portion of the back frame member and the seat support assembly; and a second spring flexibly interconnecting the second end portion of the back frame and the seat support assembly.

  • Patent number: 6749259
    Abstract: A chair includes a generally horizontal seating surface with four legs extending downwardly from the seating surface. A first stiffener bar extends between and interconnects the front left leg and the rear left leg. A second stiffener bar extends between and interconnects the front right leg and the rear right leg. A ganger feature is provided for interconnecting the chair with a like chair in a side-by-side arrangement. The ganger feature is a ganger bracket interconnected with one of the stiffener bars and extending outwardly to an outward edge. An engagement tab extends upwardly from the outward edge. The other stiffener bar has a lower surface with a slot defined therein. The slot is sized and positioned so as to receive the engagement tab of a like chair so as to interconnect the chairs.

  • Patent number: 6679551
    Abstract: A stackable chair includes a base with a pair of inverted U-shaped leg members. Each of the leg members includes a front leg portion, a rear leg portion, and a generally horizontal portion interconnecting the front and rear leg portions. The base also has a generally horizontal seat cushion frame extending between the U-shaped leg members with the transverse front spring reinforcement bar extending side-to-side. A back support frame has a generally vertical portion with an upper and lower end and a generally horizontal end portion that extends from the lower end. The generally horizontal portion includes a transverse rear spring reinforcement bar. A spring member has one end interconnected with the front spring reinforcement bar and another end interconnected with the rear spring reinforcement bar. The spring member supports the back support frame such that the back support frame has an unstressed position and a reclined position.
