ABSTRACT:
An arrangement F(1,1′,1″) for weakening a structure (4,4′,12″), comprises at least one element (8,28) arranged at the structure (4,4′,12″) to affect its strength, a sensor (9) arranged to sense impact acting on the structure (4,4′,12″) and a control unit (10) disposed to, firstly, receive signals when the signal received from the sensor (9) agrees with a set value. The element (8,28) comprises an explosive charge (11), which is disposed to detonate when the control signal is emitted from the control unit (10). The explosive charge (11) is disposed at the element (8,28) in such a manner that the element (8,28) awakens the strength of the structure (4,4′,12″) when the explosive charge (11) detonates.
