  • Joystick assembly for improved machine control
    Patent number: 8212770
    Abstract: A joystick assembly that provides enhanced operator control and stability during rough operation by being primarily rotatable about a vertical axis of a clockspring. The joystick assembly also includes a palm support that is associated with the clockspring via a clamp in the lower housing of the palm support. Further, the joystick assembly has an interface device that includes at least one input device that is conveniently actuated by an operator's thumb.

  • Seat assembly including a mechanical strut and machine using same
    Patent number: 7748785
    Abstract: A machine includes a seat assembly and a mechanical strut attached to the seat assembly. The mechanical strut, free of pneumatic seals, is positioned to move at least a portion of an armrest of the seat assembly along a horizontal axis. A length adjustment mechanism is movable to release a friction lock mechanism within the mechanical strut. The mechanical strut is telescopically movable through a continuous range of armrest lengths when the friction lock mechanism is released.
