Abstract
A resilient bumper for protecting vehicles and stationary objects against collisions comprising a plurality of spaced, adjacent fins of flexible resilient material which are so spaced that the fins abut against each other progressively as the result of an impact and thus offer progressively higher resistance as each fin contacts an adjacent fin. The fins are preferably of tough rubber or plastic material having high ultimate elongation at low temperatures, high tear strength over a wide temperature range, and high abrasion resistance. The fins may be disposed on corners of a vehicle or other objects to be protected or may be on flat, circular or other shapes. The fins may be of various shapes and may be offset or staggered relative to each other.
