Air guiding device for a motor vehicle

摘要

An air guiding device (10) for a motor vehicle, with a spoiler lip (12) extending in the transverse direction (FQ) of the vehicle, and with a pneumatic actuating device (28) for the spoiler lip (12), with the aid of which actuating device the spoiler lip (12) is shiftable between a retracted rest position and an extended position, wherein the pneumatic actuating device (28) has a pneumatic actuator (30) which is fillable with or is emptiable of air, wherein the pneumatic actuator (30) is divided in the transverse direction (FQ) of the vehicle into a plurality of zones (40, 42, 44), wherein the pneumatic actuator (30) has a plurality of air-fillable chambers (46, 48, 50) in each zone (40, 42, 44), and wherein the chambers (46, 48, 50) are fillable with or are emptiable of air in a manner individual to the zones.

主权项

1. An air guiding device for a motor vehicle, comprising:
a spoiler lip extending in a transverse direction of the vehicle; and a pneumatic actuating device for shifting the spoiler lip between a retracted rest position and an extended position, the pneumatic actuating device having a pneumatic actuator that is fillable with or emptiable of air to shift the spoiler lip between the extended position and retracted rest position, respectively, the pneumatic actuator being divided in the transverse direction of the vehicle into a plurality of zones, each of the plurality of zones having a plurality of air-fillable chambers arranged in a direction normal to the transverse direction, wherein the chambers are fillable with or are emptiable of air in a manner individual to the zones.
