Abstract

An aerodynamically effective attachment part or spoiler extension is disclosed. The spoiler extension includes a guide arrangement having a first guide element formed between the spoiler extension and a base body of the spoiler arrangement. Transfer of the spoiler extension is guided from a release position, in which the spoiler extension is detachable from the base body, along at transfer direction into a locking position, in which the spoiler extension is secured on the base body. The spoiler extension includes a securing element able to secure the spoiler extension automatically on the base body of the spoiler arrangement in the locking position.

Claims

1-15. -15. (canceled)

16. An aerodynamically effective spoiler extension for a spoiler arrangement having a base body, the spoiler extension comprising:

an extension body having at least one surface for changing the flow behavior of air flowing over the extension body;

a guide arrangement including;

a first guide element extending from the extension body, wherein a transfer of the spoiler extension along at least one transfer direction guides the first guide element from a release position in which the spoiler extension is removable from the base body into a locking position in which the spoiler extension is securable to the base body; and

a securing element extending from the extension body and configured to automatically secure the spoiler extension on the base body in the locking position.

17. The spoiler extension according to claim 16, wherein the guide arrangement further comprises a second guide element configured to extend from the base body and constructed in a corresponding complementary manner to the first guide element, the first guide element having a projection section formed transversely to the transfer direction and with which the second guide element is able to be engaged behind.

18. The spoiler extension according to claim 16, wherein the projection section comprises one of a T-shaped or double-T-shaped cross-section,

19. The spoiler extension according to claim 16, wherein the first guide element and the extension body comprise a shared component.

20. The spoiler extension according to claim 16, wherein the guide arrangement further comprises a clamping element extending from the extension body and configured to impart a clamping force at least partially transverse to the transfer direction between base body and extension body.

21. The spoiler extension according to claim 16, wherein the guide arrangement further comprises an adjusting element for adjusting an angle of inclination of the extension body with respect to the base body.

22. The spoiler extension according to claim 21, wherein the adjusting element comprises a surface shaping including a section inclined with respect to the transfer direction formed on the first guide element.

23. The spoiler extension according to claim 16 wherein the guide arrangement further comprises a securing element having a detent section extended at least partially transverse to the transfer direction, wherein the detent section is configured to be displaced on transfer from the release position and wherein upon reaching the locking position is configured to automatically engage behind a recess in the base body transversely to the transfer direction.

24. The spoiler extension according to claim 23, wherein the securing element comprises a flexible holding section prestressed into the locking position, at one end of which the detent section is arranged in order to form an L-shaped cross-section with a holding section, and which is able to be secured by an end on the extension body.

25. The spoiler extension according to claim 16, wherein the guide arrangement further comprises at least two first guide elements extending parallel to one another, and at least one securing element arranged between the at least two first guide elements, and at least one clamping means arranged between the securing element and the at least two guide elements.

26. The spoiler extension according to claim 16, wherein the guide arrangement further comprises:

a second guide element configured to extend from the base body and constructed in a corresponding complementary manner to the first guide element, the first guide element having a projection section formed transversely to the transfer direction and with which the second guide element is able to be engaged behind;

a clamping element extending from the extension body and configured to impart a clamping force at least partially transverse to the transfer direction between base body and extension body; and

an adjusting element for adjusting an angle of inclination of the extension body with respect to the base body, wherein the adjusting element comprises a surface shaping including a section inclined with respect to the transfer direction formed on at least one of the first guide element, the second guide element and the clamping element.

27. A rear spoiler arrangement for a motor vehicle comprising a base body configured to be arranged on a motor vehicle, the rear spoiler arrangement having at least one aerodynamically effective spoiler extension according to one of claim 16, wherein transfer of the spoiler extension is guided from a release position, in which the spoiler extension is detached from the base body, along a transfer direction into a locking position, in which the spoiler extension is secured on the base body, the spoiler extension having at least one securing element, by which the extension body is secured automatically on the base body in the locking position.

28. The spoiler arrangement according to claim 27, wherein the guide arrangement further comprises a second guide element constructed in a complementary manner to the first guide element and arranged on the base body, and which is engages behind by the first guide element transversely to the transfer direction in the locking position.

29. The spoiler arrangement according to claim 27 further comprising a securing element of the spoiler extension configured to be received in a recess formed in the base body in the locking position.

31. The spoiler arrangement according to claim 28, further comprising at least one adjusting element for adjusting an angle of inclination of the extension body with respect to the base body, the adjusting element including a surface shaping having an inclined section with respect to the transfer direction.

32. A motor vehicle comprising spoiler arrangement according to claim 27.

30. The spoiler arrangement according to claim 30, wherein the guide arrangement comprises at least two second guide elements extended substantially parallel to one another and with the recess arranged between at least the two guide elements.
