Abstract

An apparatus and method are provided for damping deflections and vibrations in a ski, and further for adjustably biasing a ski to enhance its performance. An elongated damping member is attached by one end to the upper surface of the ski, and bears at its other end on the upper surface of the ski to resist deflection of the end portion of the ski. The damping member may also be urged against the ski for biasing the end of the ski downward relative to the center of the ski. A resilient bearing pad may be disposed between the ski and the bearing end of the damping member. The damping member may be mounted at a lateral angle to differentially damp one side edge of the ski. The damping member is adjustable in its mounting to provide adjustable damping and biasing force. A second damping member may be mounted to the ski to damp and bias the opposite end of the ski in a like manner. A central damping member may be mounted to the center portion of the ski. A method of damping a ski is provided in which a member applies a damping force to the upper surface of the ski, and particularly at a longitudinal point along the ski where the ski primarily contacts the snow surface.
