  • Machine and pneumatic seat assembly having air container with integral air compressor housing
    Patent number: 8011468
    Abstract: A machine includes a machine body having an operator station and a seat assembly position at the operator station. The seat assembly includes a pneumatic support element that includes an air container having an air compressor positioned therein. The air container includes a deformable section, and a rigid section that includes a housing for the air compressor. Forming the air compressor housing integrally with the air container minimizes leak paths and improves packaging.

  • Electromagnetic suspension system for a seat assembly and machine using same
    Patent number: 7975813
    Abstract: A suspension system for a seat assembly of a machine includes an upper support member and a lower support member. A pair of scissors linkages interconnect the upper and lower support members. Each of the scissors linkages includes first and second arms pivotably attached at central portions thereof. An electronic controller is in communication with a pair of electromagnetic devices positioned at first ends of the first arms. The electronic controller is configured to energize the electromagnetic devices in response to a sensor output.
