Claim 0:
1. A vehicle, comprising:
a rear end,
a front end located forwardly of the rear end, wherein a direction extending from the rear end towards the front end or vice versa is defined as a longitudinal direction of the vehicle,
a chassis extending between the rear end and the front end, the chassis comprising two frame members having their main directions of extension along the longitudinal direction and being located on a respective side of a longitudinal geometrical centre axis of the chassis,
resilient elements, such as bushings, provided on the chassis, and
a collision protection structure located between the two frame members and configured to absorb energy by becoming deformed when the chassis is subjected to a rearwardly directed impact force which is greater than a threshold force, wherein the collision protection structure is suspended from the chassis by the resilient elements so as to act as a mass damper under normal operating conditions,
wherein the chassis comprises a rear cross member located rearwardly of the collision protection structure and interconnecting the two frame members of the chassis, wherein when the chassis is subjected to the rearwardly directed impart force which is greater than the threshold force, then the rear cross member acts as an abutment and counteracts or retards a rearward movement of the collision protection structure.
