Abstract
An active bolt release arrangement includes a nut having nut portions adapted for radial movement, a sleeve part encircling the nut and having contact portions in contact with the nut portions in order to prevent the nut portions from radial movement, and a pyrotechnical actuator. The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement.
