Abstract

An air deflection device of a motor vehicle includes an air deflection element and a displacement kinematic system. The air deflection element is displaceable by the displacement kinematic system from an extended deflection position, in which the air deflection element with a deflection surface in a front region of the air deflection element in a longitudinal direction of the motor vehicle diverts an airflow hitting the air deflection element in an underbody region in a forward direction of travel of the motor vehicle, into a retracted position. The air deflection element is displaceable by the displacement kinematic system rearwards in the longitudinal direction of the motor vehicle and upwards in a vertical direction of the motor vehicle and is pushable back in a direction of the retracted position in an event of an obstacle-related force component acting on the air deflection element in the longitudinal direction of the motor vehicle.
