a bushing region of the pivot hinge, coaxially surrounds the latching elements; or
the second latching element and the fourth latching element are elastically supported against each other; or
the first latching element and the third latching element are formed as identical parts; or
the second latching element and the fourth latching element are formed as identical parts.
15 . The device as claimed in claim 1 , wherein:
the pivot hinge comprises a hinge bracket for fastening to the vehicle and a pivot arm pivotable relative thereto for fastening to the air-guiding element.
16 . The device of claim 15 , wherein the hinge bracket supports the pivot arm on an upper side or a lower side of the pivot arm; or
the locking mechanism is configured such that the pivot arm does not perform an axial movement along a pivot axis of the pivot hinge during a locking process.
17 . The device as claimed claim 1 , wherein:
the pivot hinge comprises an adjustment device for precision adjustment of a pivot arm of the pivot hinge.
18 . The device as claimed in claim 17 , wherein the adjustment device is a rotatable pressure spindle, or
wherein the adjustment device adjusts the pivot arm to a predetermined position.
19 . The device as claimed in claim 1 , wherein the pivoted-out position and the pivoted-in position are spaced apart from one another by an angle of at least 40°, 50°, 60°, 70°, 80°, 90° or 100° with respect to a pivot axis of the pivot hinge.
20 . The device as claimed in claim 1 , wherein:
the device comprises a plurality of pivot hinges provided with the locking mechanism for fastening the air-guiding element to the vehicle in a spaced-apart manner, preferably in a longitudinal direction of the air-guiding element.
21 . An air-guiding device for a motor vehicle, said device comprising:
an air-guiding element, and
a pivot hinge, which is designed on the one hand to be fastened to the air-guiding element and on the other hand to be fastened to the vehicle,
wherein the pivot hinge comprises a locking mechanism which is designed to lock the pivot hinge automatically when at least one predetermined pivot position has been reached, wherein the pivot hinge is fastened to the air-guiding element.
