Instrument cluster

1. An instrument cluster, in particular for a vehicle, comprising:

a body made of light-proof material and having a cavity;

a display panel having a plurality of graphic areas;

a backlighting device arranged behind said display panel for backlighting said graphic areas; the backlighting device comprising at least one light source that is housed in said cavity of said body, and at least one light-guide element, said light-guide element including a receiving portion facing said light source for directly receiving a light beam emitted, in use, by said light source, and at least one transmitting portion for transmitting and guiding the light received by said receiving portion towards at least one of said graphic areas;

a cover supported by said body and arranged in a fixed position with respect to said light source, said cover made of light-proof material and disposed between said receiving portion and said display panel for shielding rays of light passing through said receiving portion and directed onto said display panel; and

wherein said cover has a channel, which comprises an inlet facing said receiving portion and at least one outlet facing one of said graphic areas, said channel being shaped in such a way as to transmit light indirectly from said inlet to said outlet.

2. The instrument cluster as set forth in claim 1 , wherein said channel has a cross section which defines the smallest area of said channel at said inlet.

3. The instrument cluster as set forth in claim 1 , wherein said channel comprises an initial portion, which extends starting from said inlet along a first rectilinear axis.

4. The instrument cluster as set forth in claim 3 , wherein said initial portion has a cross section that is constant along said first rectilinear axis.

5. The instrument cluster as set forth in claim 3 , wherein said outlet is provided along a second rectilinear axis that intersects with said first rectilinear axis.

6. The instrument cluster as set forth in claim 5 wherein said channel comprises an end portion, which extends along said second rectilinear axis and terminates at said outlet.

7. The instrument cluster as set forth in claim 6 , wherein the cross section of said initial portion is smaller than that of the said end portion.

8. The instrument cluster as set forth in claim 6 , wherein the cross section of said end portion increases towards said outlet.

9. The instrument cluster as set forth in claim 8 , wherein said end portion is defined by two faces that are parallel to one another and to said second rectilinear axis and by two lateral faces that diverge away from each other.

10. The instrument cluster as set forth in claim 6 , wherein said initial and end portions are joined by a surface that is shaped and oriented in such a way as to reflect the light from said first rectilinear axis to said second rectilinear axis.

11. The instrument cluster as set forth in claim 10 , wherein the cross section of said initial portion is triangular, and in that said surface extends starting from one side of the triangular cross section.

12. The instrument cluster as set forth in claim 1 , wherein said channel is empty.

13. The instrument cluster according to claim 1 , wherein said cover is fixedly coupled to said body.
