ABSTRACT:
A seat suspension for resiliently mounting an operator's seat on a vehicle for floating movement in fore-to-aft and vertical directions. The seat suspension includes a base part that has lower front and rear pivot axes and a lower spring end seat; and a support part on which the operator's seat can be mounted with the support part having upper front and rear pivot axes and an upper spring end seat. One of the spring seats has a fulcrum and a lateral movement retainer while the other spring seat has an anchor. Front and rear links pivotally interconnect the upper and lower front pivot axes and the upper and lower rear pivot axes, respectively. Compression springs each having an axis and spaced apart upper and lower end portions that are generally transverse to the spring axis are mounted between the base part and the support part. One transverse end portion of each compression spring is mounted in the anchor and secured thereby against movement. The other end portion of each compression spring is supported on the fulcrum and is secured by the retainer only against lateral movement to allow this other end portion to roll back and forth on the fulcrum and shift the angle of the spring axis.
