Abstract:
1. A vehicle-mounted device having an adjustable rigidity for absorbing crash energy, comprising: a deformation element; a housing accommodating the deformation element, wherein the housing deforms the deformation element when the deformation element is moved in a forward motion direction conditioned by the crash energy; a disengageable die arranged in the housing, for accommodating and deforming the deformation element; a supporting device arranged in the housing, wherein the supporting device is configured to (i) support, in a first position of the supporting device, 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 of the supporting device, the disengageable die for a motion for disengagement due to the radial force; and a pyrotechnic actuator generating a pressure for moving the supporting device from the first position into the second position, to adjust the rigidity of the vehicle-mounted device.
