DETAILED DESCRIPTION

(8) The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

(9) The figures show a spoiler arrangement provided as a whole with the reference number 2, in particular a rear spoiler, for a motor vehicle (only partially illustrated in the figures). The spoiler arrangement 2 includes a base body 4, which is able to be secured on the body of the motor vehicle. Furthermore, the spoiler arrangement 2 has an aerodynamically effective spoiler extension 6, which is able to be secured on the base body 4.

(10) FIG. 1 shows a perspective top view onto an aerodynamically effective spoiler extension 6. The latter includes a directing body 8, which includes at least one surface 10, by which the flow behavior of the air flowing along the surface 10 is able to be changed. In the example embodiments of the spoiler extension 6 shown in the figures, the spoiler extension 6 includes two first guide elements 12 of a guide arrangement 14. The first guide element 12 of the guide arrangement 14 are constructed such that they can engage behind the second guide element 16 of the base body 4.

(11) The second guide elements 16 of the base body 4 are engaged behind by the first guide elements 12 of the spoiler extension 6 such that a transfer of the directing body 8 is able to be guided from a release position, in which the spoiler extension 6 is able to be removed from the base body 4, along at least one transfer direction 18 into a locking position, in which the spoiler extension 6 is secured on the base body 4.

(12) Furthermore, the example embodiment of the spoiler extension 6 which can be seen from FIG. 1 includes a securing element 20, by which the directing body 8 at least in the locking position is able to be secured automatically on the base body 4 of the spoiler arrangement 2. Furthermore, the spoiler extension 6 includes a clamping element 22, by which a force acting transversely or obliquely to the transfer direction 18 is generated between the base body 4 and the directing body 6.

(13) FIG. 2 shows a perspective side view onto the base body 4, which includes two second guide element 16. Furthermore, the base body 4 includes a recess 24, into which the securing element 20 of the spoiler extension 6 is able to be engaged at least in the locking position.

(14) FIG. 3 shows a top view onto the spoiler arrangement 2, in which the spoiler extension 6 is joined to the base body 4.

(15) FIG. 4 shows a section through the example embodiment according to FIG. 3. It can be seen with the aid of FIG. 4 that the first guide element 14 includes a projection section 26, having a double-T-shaped cross-section, which is constructed such that it engages on both sides behind the second guide element 16, constructed in the manner of a rail, transversely to the transfer direction 18.

(16) FIG. 5 shows a section along the line A-A according to FIG. 4. It can be seen from FIG. 5 that an adjusting element 25 is constructed on the first guide element 14 for adjusting an angle of inclination of the directing body 8 with respect to the base body 4. The adjusting element 28 is realized here by a surface shaping of the first guide element 12.

(17) FIG. 6 shows a side sectional view along the section line B-B according to FIG. 4. It becomes clear from FIG. 6 that the securing element 20 includes a detent section 30, which engages at least in the locking position into the recess 24 of the base body 4 and includes a holding section 32, with which the detent section 30 forms an L-shaped cross-section and which is secured on the directing body 8.

(18) While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims and their legal equivalents.
