Problems solved by technology

[0005] However, the passage of light in the support layer also results in the diffusion of light in the interior of the support layer due to the crystallinity or charge of the polymeric material forming the support layer.
This causes the light to diffuse outside the area where the pictographic pattern is formed
As a result the image of the pictogram becomes blurred and the resulting aesthetically unsatisfactory result

Embodiment Construction

[0024] In the description, "outside" means visible from the cabin of the motor vehicle, and "inside" means not visible from the cabin of the motor vehicle. The terms "upper" and "lower" are defined with respect to a direction from the walls of the cabin and towards the interior of the cabin.

[0025] refer to figure 1 , describes a decorative panel 1 comprising a translucent skin 2 and a support layer 4 arranged against an inner surface 6 of this skin 2 .

[0026] The support layer 4 is rigid. Rigid means that the support layer 4 is made of a material that does not substantially collapse under pressure, unlike eg foam, which is a soft material. In a foam material the light rays are diffused by the presence of air bubbles in the material, whereas with the rigid material of the support layer 4 the path of the light rays is not disturbed by the presence of air bubbles. The support layer is for example made of a glass-filled translucent polymeric material and is attached to the...

Abstract

This panel (1) includes at least one zone (10) forming a pictogram (12), the pictogram (12) being illuminated by a light source (14) placed beneath the lining panel (1), the lining panel (1) having a translucent skin (2) forming the external surface (8) of the lining panel (1) and a support layer (4) placed against the skin (2) between the light source (14) and at least the zone (10) forming a pictogram (12). The support layer (4) has at least a first thickness (e1) around the zone (10) forming the pictogram (12) and at least a second thickness (e2) facing the zone (10) forming the pictogram (12), the second thickness (e2) being smaller than the first thickness (e1).

Description

technical field [0001] The invention relates to a trim panel for a motor vehicle, said trim panel comprising at least one area forming a pictogram illuminated by means of a light source arranged below the trim panel, the trim panel comprising A translucent skin of the outer surface of the panel and a support layer arranged against the skin between the light source and at least said pictographically patterned area. [0002] The invention also relates to a motor vehicle comprising such a trim panel. Background technique [0003] Pictogram means any graphic or symbolic pattern, including alphanumeric symbols, used for communication purposes. [0004] In known decorative panels of the type mentioned above, the light source is arranged below the support layer. The light thus passes through the support layer and then through the translucent skin where it is diffused in the shape of the pictographic pattern defined by the covering. Such a decorative panel is described, for examp...
