Air guiding device for a motor vehicle

摘要

An air guiding device (10) for a motor vehicle has a spoiler lip (12) mountable on a front part (8) of the motor vehicle via an adapter (32) and extends in the transverse direction (FQ) of the vehicle. A pneumatic actuating device (28) shifts the spoiler lip (12) between a retracted rest position and an extended position. A flexurally elastic rod (24) is guided in a guide (26) near the free end of the spoiler lip (12). The spoiler lip (12) is mounted on the adapter (32) so that the spoiler lip (12), even in the retracted rest position, is under a prestress that opposes the shifting of the spoiler lip (12) out of the rest position into an extended position.

主权项

1. An air guiding device for a front part of a motor vehicle, comprising:
an adapter mounted to the front part of the motor vehicle; a spoiler lip extending in a transverse direction of the vehicle, the spoiler lip having a first end mounted to the adapter and a free end spaced from the first end; a pneumatic actuating device for shifting the spoiler lip between a retracted rest position and an extended position; a guide device formed in proximity to the free end of the spoiler lip and extending in the transverse direction; a flexurally elastic rod disposed in the guide device; and at least one spiral spring extending spirally around the flexurally elastic rod and fixedly connected in the spoiler lip in a prestressed state so that the at least one spiral spring exerts a prestress on the spoiler lip into the rest position.
