摘要： A cordless, power-adjustable office or task chair comprising: a seat height adjustment mechanism, including an electric motor, the upper and lower members of the adjustable column relative to each other to raise and lower the height of the seat. A seat tilt adjustment mechanism, including an electric motor, moves the top plate relative to the bottom plate to adjust the angle of tilt of the seat. A seat position adjustment mechanism, including an electric motor, moves the seat relative to the top plate. A back tilt adjustment mechanism, including an electric motor, moves the back support strap to tilt the chair back forwardly and rearwardly. A back height adjustment mechanism, including an electric motor, moves the back axially with respect to the back support strap. A seat height switch controls the seat height adjustment mechanism. A seat tilt switch controls the seat tilt adjustment mechanism. A seat position switch controls the seat position adjustment mechanism. A back tilt switch controls the back tilt adjustment mechanism. A back height switch controls the back height adjustment mechanism. Each of the switches is positioned so as to be operable by a user seated on the chair.

摘要： A method for retrofitting an adjustable chair including a seat, a pedestal base, and a gas cylinder that extends therebetween is provided. The method includes the steps of uncoupling the gas cylinder from the chair, and coupling a height adjustment mechanism to the chair that is configured to electrically adjust a height of the seat relative to the pedestal base. The height adjustment mechanism coupled to the chair being retrofitted includes a limit switch that is configured to limit an amount of movement of the height adjustment mechanism. The method also includes the step of coupling the pedestal base to the height adjustment mechanism.
