    摘要： An adjustable seat assembly including a base, a seat support, and means for independently adjusting the vertical elevation of the front and rear portions of the seat support relative to the base including on each side of the assembly a pair of lever arms each being pivotally connected to the base and independently pivotally connected to the seat support. The pivotal connection of each of the levers to the seat support is disposed inwardly and between the pivotal connections of the levers to the base. The inward end of each of the levers has formed thereon a plurality of notches. Latch plates pivotally mounted on the seat support include tapered teeth engageable with any of the notches in the associated lever arms to latch the lever arms in desired angular dispositions corresponding to desired elevations. A pivotal control link is operable by way of an actuator arm to selectively disengage the latch plates from the associated lever arms. The lever arms and control links on opposite sides of the seat assembly are interconnected for synchronous operation. The base is longitudinally slidable to provide fore-and-aft adjustment.

    摘要： An adjustable seat supporting assembly including a pair of spaced seat support members and base means. The seat support members are supported on the base means by elongated levers. Each lever is pivotally connected to the base means and independently pivotally connected to the seat support members. There are two sets of levers on each side of the assembly. The levers on each side of the assembly have ends facing one another with notches therein. Control links and latching plates are secured to the seat support members for selectively allowing the levers to pivot to adjust the vertical position of the seat support members. The improvement comprises the use of a torsion bar associated with the levers at the rear of the assembly. The torsion bar is twisted to react between the seat support members and the rear levers to urge the rear levers to pivot in a manner to raise the rear portion of the seat support members.
