Description

[0022] Other particular features and advantages of the invention will emerge on reading the description given hereinbelow of particular embodiments of the invention, given in an indicative but nonlimiting manner, with reference to the attached drawings in which:

[0023] FIG. 1 is a perspective schematic view of an element of the subject of the invention;

[0024] FIG. 2 is a partial perspective schematic view of the rear of a motor vehicle provided with the subject of the invention;

[0025] FIG. 3 is a top schematic view of the subject of the invention;

[0026] FIG. 4 is a partial perspective schematic view of another element of the subject of the invention; and,

[0027] FIG. 5 is a partial schematic view of the subject of the figure [FIG. 4] equipped with the subject of the figure [FIG. 1], according to the arrow V illustrated in the figure [FIG. 3].

[0028] FIG. 1 shows a signal reception device 10 comprising a reception plate 12 and a reception unit 14. The reception plate 12 is of square form and its dimensions here are, for example, 90 mm×90 mm, while its thickness is 2 mm. The reception plate 12 can have greater thicknesses, but also less than 2 mm. It is made of metal so that the electromagnetic signals coming from artificial satellites can interact with it.

[0029] It has two opposite lateral borders 16, 18 and an anterior edge 20 opposite a posterior edge 22. Also, the reception unit 14, with a thickness of around 20 mm, is mounted in fixed position on the reception plate 12, at the center between the two opposite lateral borders 16, 18. The reception unit 14 comprises two connectors 24, 26 emerging toward the anterior edge 20, to be able to connect it to coaxial cables extending to the display and control instruments of a motor vehicle.

[0030] The signal reception device 10 is, here, a “GNSS patch”, in other words, a reception element that makes it possible to receive information elements on its position, its speed and the time, using a set of satellites moving around the earth; “GNSS” corresponding to the initials of “Global Navigation Satellite System”.

[0031] Reference will now be made to FIG. 2, showing the rear of a motor vehicle 28 having a roof 30 extended toward the rear according to the component X of a rear spoiler 32 overhanging a rear tailgate 34. Thus, the rear spoiler 32 extends transversely over the width of the roof 30 that it extends. It comprises an oblong outer wall 36 which has a front edge 38, which comes edge-to-edge with the roof 30, and a rear edge 40 running along the tailgate 34. Also, the oblong outer wall 36 has a part forming a convex side 42 opposite a part forming a concave side 44; the two parts 42, 44 being delimited from one another by a trailing edge 46. Thus, the signal reception device 10, described level in the figure [FIG. 1] is installed inside a first internal housing 48 of the rear spoiler 32 that is illustrated in top view in the figure [FIG. 3] without its outer wall but showing a frame 50 on which it rests.

[0032] The framework 50 has a front part 52 and a rear part 54 set back with respect to the front part 52. The first internal housing 48 is situated in the rear part 54 between two lateral partitions 56, 58.

[0033] Reference will now be made to the figure [FIG. 4] partially showing, according to the arrow V represented in the figure [FIG. 3], the rear part 54 and the two lateral partitions 56, 58 then defining the first internal housing 48.

[0034] Thus, the two lateral partitions 56, 58 extend longitudinally parallel to one another according to the longitudinal axis X. They are spaced apart by a distance substantially greater than 90 mm. Also, they are respectively provided with two flat profile sections 60, 62 extending parallel to one another and each having a bearing edge 64, 66. And they are also equipped with two prismatic profile sections 68, 70 extending overhanging the bearing edges 64, 66 at a distance of 2 mm. The two flat profile sections 60, 62 are, here, linked by a bridge 72. And from this bridge 72 extend two flexible tongues 74, 76 that are respectively parallel and situated close to the two flat profile sections 60, 62 substantially below the level of their bearing edge 64, 66. The flexible tongues 74, 76 extend according to a negative component of the longitudinal axis X and they are each terminated by a stop lug 78 protruding above the level of the bearing edge 64, 66 of the flat profile sections 60, 62, when the flexible tongues 74, 76 are at rest. Furthermore, stop lugs 78 extend in line with the front ends 80 of the two flat profile sections 60, 62. That way, the two bearing edges 64, 66 respectively covered by and at a distance from their two prismatic profile sections 68, 70 then define two runners opposite one another 82, 84.

[0035] Furthermore, and particularly advantageously, the two flat profile sections 60, 62, the two prismatic profile sections 68, 70, the bridge 72 and the two flexible tongues 74, 76 respectively terminated by their stop lug 78, are molded in a single piece with the rear part 54 and the front part 52 on the two lateral partitions 56, 58. The assembly is for example molded in ABS.

[0036] Thus, the tongues 74, 76 exhibit a certain flexibility, and they can be moved apart opposite the two prismatic profile sections 68, 70 so as to be able to engage the posterior edge 22 and the two opposite borders 16, 18 of the reception plate 12 in the two runners, respectively 82, 84, between the bearing edges 64, 66 and the prismatic profile sections 68, 70, as illustrated in the figure [FIG. 5].

[0037] Since the two lateral partitions 56, 58 are moved apart from one another according to the transverse axis Y by a value corresponding to the width of the reception plate and since the prismatic profile sections 68, 70 are spaced apart from the bearing edges 64, 66 according to the vertical axis Z by a distance equal to the thickness of the reception plate 12, and since, in addition, all these elements are made of polymer material, the two opposite lateral borders 16, 18 of the reception plate 12 can be driven by force between these elements, while the polymer materials deform significantly. Also, at the end of the bearing edges 64, 66, opposite the front ends 80, stop abutments that are not represented make it possible to stop the reception plate 12 when the posterior edge 22 comes precisely against the stop abutments. In the longitudinal direction X, the stop lugs 78 are situated at a distance from the stop abutments substantially greater than the length of the reception plate 12, i.e. 90 mm. That way, when the posterior edge 22 comes against the stop abutments, the tongues 74, 76 revert to their position of equilibrium, while the lugs 78 extend facing the anterior edge 20 of the reception plate 12 so as to hold it captive. That way, the reception plate 12 and the reception unit 14 that it supports are perfectly held in fixed position with respect to the framework 50 and, more generally, to the rear spoiler 32.

[0038] Next, the coaxial cables of the display and control instruments can be connected to the connectors 24, 26.

[0039] Also, and conversely, the reception plate 12 can easily be extracted from the runners 82, 84 by exerting a force on the lugs 78, in the vertical direction Z and, thereby, by moving the tongues 74, 76 away from the reception plate 12. The anterior edge 20 of the reception plate 12 then escapes from the reach of the lugs 78. The reception plate 12 can then be slidingly driven to be extracted.

[0040] Thus, the reception device 10 is equally as easy to install as it is to extract.

[0041] Moreover, according to another embodiment of the invention that is not represented, the rear spoiler further comprises a second internal housing, situated for example opposite the first with respect to a median plane of the rear spoiler. Also the latter comprises two second substantially parallel longitudinal fixing supports situated inside the second internal housing, each with a second runner. And a second signal reception device comprises a second reception plate having two second opposite borders and a second reception unit installed on the second plate between the second opposite borders. Also, the second opposite borders can slide in the second runners.
