energy resulting from the impact of a vehicle and allow it to be redirectioned application_number US 57315705 A description the present invention provides a side impact vehicle detention system with great detention and energetic absorption capacity which simultaneously has the following advantageous technical characteristics as regards the state of the art in which the problems presented by the same are solved i great absorption capacity of the energy resulting from a vehicle impact to provide the detention system with an elastoplasticity behaviour and with this to decrease its rigidity to prevent the detention system from causing equivalent damages or worse than those the road users require to be protected from ii great decreasing capacity of the deceleration levels that are produced in the light vehicle during impact to decrease the severity of impact and with this the risk of injuries to the vehicle occupants iii great control capacity over the vehicle during and after collision reducing with this the possibility of its subsequent undesired reactions turns overturning unexpected trajectories etc and achieving an exiting trajectory as parallel as possible to the detention system thus reducing the risk of secondary collisions of the vehicle or with other road users iv great control capacity of the absorbed energy to provide the detention system with a certain capacity of similar deformation after each vehicle impact and thus contributes to.
