A device having an adjustable rigidity for absorbing crash energy, includes: a housing for accommodating and deforming a deformation element when the deformation element is moved in a forward motion direction due to the crash energy; a disengageable die situated in the housing for accommodating and deforming the deformation element; a supporting device situated in the housing and configured to support, in a first position, the disengageable die against a radial force of the deformation element acting in a transverse direction to the forward motion direction, and (ii) release, in a second position, the disengageable die for a motion for disengagement due to the radial force; and a pyrotechnic actuator moving the supporting device from the first position into the second position, to adjust the rigidity of the device. |
