An adjustable seat suspension, particularly suitable for a vehicle seat, includes a linkage assembly to maintain parallel motion between the seat and a support frame, as well as a suspension mechanism for controlling the motion of the seat relative to the support frame. The linkage assembly consists of three parallel link arms, each pivotally connected at its ends to the seat frame and support frame respectively. Each pivotal connection includes a self-aligning bearing. The suspension mechanism includes a spring and a damping member connected to a link arm, as well as an adjustment mechanism for selectively varying the distance between the suspension mechanism and the pivot axis of the link arm, to thereby vary the suspension characteristics of the seat. |
