Abstract
Abstract A ski suspension assembly including support means mounted to a ski, lever arm means pivotally attached to the support means for pivotal motion in response to motion between an attached member (the steering spindle) and the ski, bracket means mounted to the ski and spaced from the support means, and resilient means comprising a coil spring-shock absorber combination disposed between the lever arm means and the bracket means for resisting the pivotal motion of the lever arm means.
