An energy absorbing device formed from an integral molded unit of an elastomeric material such as polyurethane. The unit is composed of an annular body portion having an elliptical configuration with relatively thick wall sections and a pair of impact elements projecting from the outer surface of the body portion at stations which lie generally along the minor axis of the elliptical configuration. The resilience of the body portion, and to a more limited extent the impacting elements, allows the device to absorb energy when objects strike the projecting ends of the impact elements.
