ARRANGEMENT OF A SENSOR WHICH HAS A SENSOR-ACTIVE SURFACE ON AN EXTERIOR ATTACHMENT PART OF A VEHICLE

An arrangement for a sensor having a sensor-active surface on or behind an exterior attachment part of a vehicle includes a sensor guide. The sensor guide includes a traction element made of a shape-memory alloy and a restoring element. The traction element moves the sensor in the direction of the vehicle interior between an active position and a protected position in response to a detected impending collision in the low-speed range or a detected collision in the low-speed range. The restoring element moves the sensor back to the active position from the protected position.
