Abstract:
An underrun protection arrangement for a frame-including vehicle (1), the arrangement comprising:an impact element (7) positioned to confront an anticipated stress from a force, F, experienced in the event of a collision with another vehicle (2); at least one link element (8) connected to the impact element (7) and configured to be pivotably fixed to a frame member (3) of an incorporating vehicle (1); and an energy-absorbing element (11) connected to the impact element (7) and interconnectable to the frame (3), the energy-absorbing element (11) being adapted to be compressed in the event of pivoting movement of the impact element (7) and further comprising at least one locking element (10) adapted to permit pivoting movement of the impact element (7) only in the event of a force being imposed on the impact element (7) of a magnitude that exceeds a predetermined force limit, wherein said predetermined force limit is defined as an anticipated stress in the event of a collision with a passenger car following essentially complete compression of crumple zones provided in the passenger car.
