摘要

The device (1) has an electric motor-free actuator system (103) which causes a movement or resizing of a component for effecting the unlocking or locking of a steering column (101). The steering column is held in a housing (102) in a longitudinally movable manner. The actuator system includes a shape memory alloy (104). The actuator system has a spring (105), where the shape memory alloy is electrically controlled for unlocking the steering column such that the spring force of the spring generates counteracting force.
