The present disclosure relates to an arrangement comprising a pyrotechnical device and a first mechanical structure. The pyrotechnical device is adapted to, directly, or indirectly, influence the first mechanical structure at a first location, such that the first mechanical structure is exposed to a deformation and/or a displacement. The deformation and/or displacement of the first mechanical structure at the first location is adapted to at a second location, being different from the first location, change a functional mode of the first mechanical structure and/or of a second mechanical structure connected to the first mechanical structure by means of direct mechanical influence. The disclosure further relates to a vehicle comprising such an arrangement.
