    • An adjustable chair includes upper and lower base members, a seat assembly secured to the upper base member, and a chair adjusting mechanism. In an embodiment the upper base member is connected to the lower base member by first and second linking members each having a first end connected to the lower base member and a second end slideably received in corresponding first and second arcuate tracks disposed in the upper base member, such that movement of the second ends into and out of the tracks results in vertical movement of the seat assembly relative to the base. In a further embodiment the seat bottom and seat base comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat bottom to tilt relative to the seat base. In a further embodiment the seat bottom and seat back comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat back to recline relative to the seat bottom.
    • 一种可调节椅子,包括上部和下部基座构件,固定到上部基座构件的座椅组件和椅子调节机构。 在一个实施例中,上部基座构件通过第一和第二连接构件连接到下部基座构件,第一和第二连接构件各自具有连接到下部基座构件的第一端和可滑动地接收在设置在上部基座构件中的对应第一和第二弧形轨道中的第二端 ,使得第二端部进出轨道的运动导致座椅组件相对于基部的垂直运动。 在另一实施例中,座椅底部和座椅底座包括协作的弓形轨道,轨道和/或轴承构件,其中弓形轨道,轨道和/或轴承构件的协作动作使得座​​椅底部能够相对于座椅底座倾斜。 在进一步的实施例中,座椅底部和座椅靠背包括协作的弓形轨道,轨道和/或支承构件,其中弓形轨道,轨道和/或支承构件的协作动作使得座​​椅靠背相对于座椅底部倾斜。
