1-2. (canceled)
A crash-protected steering device of a vehicle, comprising:
- a first guide element connected to a vehicle superstructure, and
- a second guide element connected to the first guide element, the first and second guide elements being connected to one another for energy-consuming displacement with respect to one another, during a vehicle crash, with a presettable release force, and
- a piezoelectric actuator provided for a controllable reduction in the preset release force.
Dependencies are inferred from the claim text.
