Estimating the term…
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.
An air guiding device for a motor vehicle, comprising:
An air guiding device for a motor vehicle, with a spoiler lip extending in the transverse direction of the vehicle, and with a pneumatic actuating device for the spoiler lip, with the aid of which actuating device the spoiler lip is shiftable between a retracted rest position and an extended position, wherein the pneumatic actuating device has a pneumatic actuator which is fillable with or is emptiable of air, characterized in that air-fillable chambers of the pneumatic actuator are manufactured from an inner, gas-tight layer and an outer protective layer.
The air guiding device of claim 8, characterized in that the gas-tight layer is manufactured from a thermoplastic elastomer and the protective layer is manufactured from a nylon fabric.
An air guiding device for a motor vehicle, with a spoiler lip extending in the transverse direction of the vehicle, and with a pneumatic actuating device for the spoiler lip, with the aid of which actuating device the spoiler lip is shiftable between a retracted rest position and an extended position, wherein the pneumatic actuating device has a pneumatic actuator which is fillable with or is emptiable of air, characterized in that the spoiler lip and an adapter device, on which the spoiler lip acts at one end which is opposite a free end of same, are assigned magnetically active holding elements, with the aid of which the spoiler lip is held on the adapter device in the retracted rest position, wherein the magnetically active holding elements are covered by plastic.
The air guiding device of claim 11, wherein the magnetically active holding elements assigned to the adapter device are covered with plastic in such a manner that said holding elements are jointly mountable in the form of a strip-like formation on the spoiler lip.
