Abstract
A dust shield for use with a damper includes a hollow cylindrical body having first and second ends. A plurality of convolutions are provided in the outer surface of the body between its ends. A plurality of inwardly projecting fingers are provided in the body portion. Each finger includes a centering rib extending to the damper to prevent shifting of the dust shield during use, thereby eliminating contact between the dust shield and a surrounding coil spring or a bump plate mounted on the damper. Additionally, each finger includes a retaining wall. The bump plate engages the retaining wall during rebound of the damper to pull the dust shield to its approximate original length to provide full-time cover of a piston rod of the damper.
