    Abstract: A tiltable chair including a base, a fulcrum member having a curved support surface, a back support pivotally connected to the base at a pivot axis and pivotable between at least an upright position and a rearward tilt position, and at least one leaf spring having first and second ends, with the first end being restrained by the base. The at least one leaf spring engages the curved support surface of the fulcrum member at a first contact point when the back support is in the upright position and at a second contact point when the back support is in the rearward tilt position, wherein the second contact point is positioned rearwardly on the at least one leaf spring relative to the first contact point. A link member is pivotally connected to the back support at a first pivot location and is pivotally connected to the at least one leaf spring at a second pivot location. The link member defines a vector between the first and second pivot locations and the first pivot location and the pivot axis define a plane. The vector and the plane define a first angle when the back support is in the upright position and a second angle when the back support is in the rearward tilt position, wherein the second angle is closer to ninety degrees than the first angle. A method of using a chair is also provided.

    Abstract translation: 一种可倾斜的椅子，包括一个底座，一个具有弯曲的支撑表面的支点构件，一个在枢转轴线处可枢转地连接到该基座并在至少一个直立位置和一个向后倾斜位置之间可枢转的后支撑件，以及至少一个板簧， 和第二端，第一端被基座约束。 当背部支撑件处于直立位置时，至少一个叶片弹簧在第一接触点处接合支点构件的弯曲支撑表面，并且当后支撑件处于向后倾斜位置时，该第二接触点处于第二接触点处，其中第二接触点 点相对于第一接触点向后定位在至少一个板簧上。 连杆构件在第一枢转位置枢转地连接到后支撑件，并且在第二枢转位置枢转地连接到所述至少一个板簧。 连杆构件限定第一枢转位置和第二枢转位置之间的向量，并且第一枢转位置和枢转轴线限定平面。 当背部支撑件处于直立位置时，矢量和平面限定第一角度，并且当后部支撑件处于向后倾斜位置时第二角度，其中第二角度比第一角度更接近九十度。 还提供了使用椅子的方法。

    Abstract: A control device for an adjustable seating structure including a first adjustment control positioned in an orientation approximating a seat member. The first adjustment control is moveable about a horizontal axis. A second adjustment control is positioned adjacent the first adjustment control in an orientation approximating a backrest member. The second adjustment control is moveable about the horizontal axis. The first adjustment control and the second adjustment control in combination generally resemble a seating structure. A seating structure including the control device is also provided.
