<p>A damper assembly (22) is useful for controlling elevator ride quality. The damper assembly (22) includes a resilient member that deflects responsive to a load. An effective stiffness of the resilient member is less than an associated rate of deflection of the resilient member. The resilient member includes a first portion (30, 40) that deflects prior to a second portion (32, 42) responsive to an initial loading on the damper assembly (22).</p>
