Abstract
An impact attenuator, which is arranged to be flexible longitudinally as well as sideways, has a rear part with two wheels, an attenuating part, a front part with two pivot wheels, and a coupling part for connection to a vehicle. The coupling part has a damper for dampening part of the force during a collision against the impact attenuator. During a minor collision against the impact attenuator the collision force is mainly absorbed by the damper. The damper regains after a collision its original position and the impact attenuator can remain operative. During a larger collision against the impact attenuator, the collision forces are also absorbed by the attenuating part.
