    摘要： A chair is provided having a seat with a resiliently deflectable shell defining a front portion thereof. The front shell is deflectable downwardly in response to the user. An adjustment mechanism is provided which controls the deflected position of the front shell section to provide for controlled deflection of the seat which adjusts the effected length of the seat while also providing for user responsive deflection of the seat.

    摘要： 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. In the unstressed position, the generally horizontal portion of the back support frame is generally co-planar with the seat cushion frame. In the recline position, the generally vertical portion of the back support frame is moved rearwardly, and the generally horizontal portion of the back support frame is moved downwardly. The spring member biases the back support frame into the unstressed position. A seat cushion is supported by the seat cushion frame and the generally horizontal portion of the back support frame.

    摘要： A chair back upright rotates about a pivot axis with respect to a chair seat plate and has a protrusion on the bottom portion thereof. When the occupant of a chair reclines, the protrusion on the back upright and the stop make contact with each other. The contact stops the rotation of the back upright. The lever handle, fixedly attached to the stop, can be rotated thereby providing more or less rotation of the back upright before contacting the protrusion and the stop occurs.

    摘要： A control mechanism for a chair that enables a plurality of adjustments to be made to the chair by a seated occupant in a cost effective and reliable manner is described. The control mechanism includes a plurality of motor-gear groups and at least one control switch. The control switch is coupled to each motor-gear group, a rechargeable battery, and to a limit switch that limits an amount of height adjustment of the chair seat with respect to the chair base. Each motor-gear group is coupled to a drive shaft. As a result, a seated occupant may engage the control switch to selectively electrically raise or lower the chair seat relative to the chair base, tilt the chair seat relative to the control mechanism, tilt the chair back relative to the chair seat, adjust the height of the chair seat relative to the control mechanism, and adjust the chair seat depth relative to the chair back.
