Abstract:
1. A suspension system for a seat assembly of a machine, comprising: an upper support member; a lower support member; a plurality of guide pins interconnecting the upper and lower support members at perimeters thereof, wherein the guide pins are vertically aligned and telescopically movable to adjust a distance between the upper and lower support members, wherein the guide pins maintain a vertical alignment of the upper support member relative to the lower support member and have a non-pivotable attachment to each of the upper and lower support members; a plurality of suspension devices operatively connected to the upper and lower support members at opposing ends thereof for biasing the upper support member away from the lower support member, wherein each of the suspension devices is positioned between two of the guide pins; and two cross-mounted dampers coupled to the upper and lower support members at positions offset from a center of the upper support member for damping a vibration of the upper support member in response to a movement permitted by the guide pins, wherein a first damper is mounted along a first axis having a first angle greater than zero with respect to the guide pins and a second damper is mounted along a second axis having a second angle greater than zero with respect to the guide pins, wherein the first angle and the second angle are different.
