    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： A seat assembly comprising a molded foam cushion having laterally spaced bolster portions, a molded plastic pad secured to the bottom of the cushion and having a fine grid and at least two heavy strands. There are openings in the cushion directly above the heavy strands which locate and receive hooks for securing a trim cover to the heavy strands through the cushion. The cushion is secured to a seat frame having seat surface springs.

    摘要： Seat positioning mechanism comprising a pair of elongated members slidably connected for telescopic movement between extended and retracted positions with respect to each other. One of the members carries friction lock means movable between a lock position on frictional engagement with the other member to frictionally restrain the members in any selected position between the extended and retracted positions against relative movement with respect to each other, and an unlock position to permit free relative movement of the members. The friction lock means is interconnected with the other member by locking and biasing means including a return spring and a plunger. The plunger has a base with arm means projecting therefrom, the base extending transversely of the longitudinal axis of the members and engaging the friction lock means on one side thereof, while the arm means extends from the base to the opposite side of the friction lock means. The return spring is connected between the other member and the end of the arm means opposite the base to resiliently urge the members toward the retracted position and the friction lock means toward its locked position.

    摘要翻译： 座椅定位机构包括一对细长构件，其可滑动地连接，用于相对于彼此延伸和缩回位置之间的伸缩运动。 其中一个构件承载摩擦锁定装置，其可在与另一构件摩擦接合的锁定位置之间移动，以在相对于彼此的相对运动之间摩擦地限制构件处于延伸位置和缩回位置之间的任何选定位置，以及解锁位置，以允许 会员的自由相对运动。 摩擦锁定装置通过包括复位弹簧和柱塞的锁定和偏置装置与另一个构件互连。 柱塞具有基部，其臂部从其突出，所述基部横向于构件的纵向轴线延伸并且在其一侧与所述摩擦锁定装置接合，同时所述臂装置从所述基座延伸到所述摩擦锁定装置的相对侧 。 复位弹簧连接在另一个构件和臂的端部相对的基座之间，以弹性地将构件推向缩回位置，并且摩擦锁定装置朝向其锁定位置。
