Description

Title of the invention: Glass for a lighting device comprising means for alignment with a bumper skin Technical field to which the invention relates

[0001] The present invention falls within the technical field of the automotive industry, in particular in the field of lighting devices intended to be integrated into the bodywork of a motor vehicle. Technological background

[0002] Daytime running lights are fitted to motor vehicles to increase their visibility during the day, particularly in conditions of reduced light, such as fog or rain. Daytime running lights, also known by the English acronym "DRL", for "Daytime Running Lights", are generally less intense than dipped or main beam headlights, but they are designed to be sufficiently visible to other road users.

[0003] Daytime running lights are located at the front of the motor vehicle, at its front bumper, under the headlights or around them, and can have different shapes and sizes depending on the design of the vehicle.

[0004] To do this, a cutout can be made in the bumper skin of a motor vehicle, corresponding to the shape and size of the glass of the daytime running light to be integrated. The bumper skin partially covers the glass in order to avoid the appearance of a visible space between these two elements.

[0005] This method allows for precise integration of the daytime running lights into the bumper skin, but it can lead to problems with dirt and residue accumulation between the bumper skin and the glass.

[0006] Particularly when this covering is carried out at one side of the front of the vehicle, because this covering is more exposed to the wind generated by the vehicle when it moves forward. A build-up of dirt can make cleaning and maintenance of the glass more difficult.

[0007] The invention aims to prevent this phenomenon of accumulation of dirt between the glass of a daytime running light and a bumper skin, in particular when these elements overlap on one side of a motor vehicle. Subject of the invention

[0008] For this purpose, the invention provides a lens for a lighting device of a motor vehicle. Preferably, the lighting device is a daytime running light for a motor vehicle.

[0009] The invention is remarkable in that the glass comprises a front face and at least a side wall extending perpendicularly or substantially perpendicularly to the front face of the window, and the front face has an appendage which extends beyond its side wall so as to form a housing intended to allow the insertion of an edge of a bumper skin to allow the alignment of the bumper skin with the window.

[0010] The term "glass" means the transparent or translucent part of a lighting device that allows light to pass through. This glass can be made from different materials, such as glass or plastic, and can have different shapes and sizes depending on the design of the vehicle and the location of the lighting device.

[0011] Remarkably, the glass according to the invention comprises an appendage extending beyond a side wall of the glass so as to form a housing capable of receiving an edge of a bumper skin. Thus, advantageously, the glass can extend above a bumper skin and thus prevent a phenomenon of accumulation of dirt at the junction between the appendage of the glass and the bumper skin, in particular when the appendage extends over an edge of a motor vehicle equipped with said glass because the dirt will naturally tend to flow along the motor vehicle when it moves, without being hindered at the junction zone between the glass and the bumper skin.

[0012] The term "side wall" preferably means a wall of the glass intended to surround or be inserted into a housing of a lighting device of the daytime running light type.

[0013] According to a preferred embodiment of the invention, the side wall designates a wall intended to extend parallel or substantially to one side of a motor vehicle.

[0014] According to another embodiment, the glass comprises at least one rib connecting its appendage to its side wall. By the term "rib" is meant here a protuberance of the glass projecting into the housing formed by its appendage and its side wall.

[0015] According to another embodiment, at least one rib is perpendicular or substantially perpendicular to the appendage and / or perpendicular or substantially perpendicular to the side wall of the glass.

[0016] According to another embodiment, at least one rib has a thickness measured in a direction parallel or substantially parallel to the side wall of the glass, between 1 cm and 5 cm, preferably between 2 cm and 3 cm.

[0017] According to another embodiment, the appendage of the ice comprises an internal face facing its side wall, and the internal face comprises at least one cavity intended to accommodate a lug of a bumper skin. By the term "lug", we mean means a protrusion present on the surface of a bumper skin.

[0018] According to another embodiment, the ice appendage extends beyond its side wall by at least 2 cm, preferably by at least 5 cm.

[0019] According to another embodiment, the appendage of the ice forms with its side wall an angle whose value is between 20° and 60°, preferably between 30° and 50°.

[0020] According to an alternative embodiment, the appendage may have a curved or substantially curved shape.

[0021] According to another embodiment, the appendage extends over at least 60%, preferably over at least 90% of the side wall of the ice.

[0022] The invention also relates to a lighting device for a motor vehicle, preferably of the daytime running light type, comprising a lens according to the invention.

[0023] The invention also relates to a bumper skin comprising an edge capable of being inserted into a housing formed by an appendage and a side wall of a window according to the invention.

[0024] According to another embodiment, the edge of the bumper skin comprises at least one notch capable of receiving a rib extending between the appendage and the side wall of the window as described above, in order to prevent movement of the bumper skin along the side wall of the window.

[0025] According to another embodiment, the edge of the bumper skin comprises on its surface at least one lug capable of guiding the insertion of the edge of the bumper skin into the housing formed by the appendage and the side wall of a window described above.

[0026] According to another embodiment, the edge of the bumper skin comprises on its surface at least one lug capable of being inserted into a cavity of a window as described above, in order to prevent movement of the bumper skin along the appendage of the window.

[0027] The invention also relates to a motor vehicle equipped with a window and a bumper skin as described above. Description of figures

[0028] The invention will be better understood from the following description, which relates to preferred embodiments, given as non-limiting examples, and explained with reference to the appended schematic drawings, in which:

[0029] [Fig-1] illustrates a partial and perspective view of a mirror according to the invention, for a luminous device of a motor vehicle;

[0030] [Fig.2] illustrates a partial perspective view of an edge of a bumper skin according to the invention, intended to cooperate with a window represented by [Fig.l];

[0031] [Fig.3] illustrates a partial and perspective view of a bumper skin re- presented by [Fig.2], held by a mirror represented by [Fig.l];

[0032] [Fig.4] illustrates another partial and perspective view of a bumper skin re shown in [Fig.2], held by a mirror shown in [Fig.l]. Detailed description of the invention

[0033] As a reminder, the invention aims to prevent the phenomenon of dirt accumulating between the glass of a daytime running light and a bumper skin, in particular when these elements overlap on one side of a motor vehicle.

[0034] [Fig.l] illustrates a partial view of a non-limiting embodiment of a window according to the invention. The window 2 comprises a front face 4 intended to protect at least one light source present in a lighting device of a motor vehicle of the daytime running light type.

[0035] The glass 2 is transparent or translucent. The glass can be made from different materials, such as glass or plastic, and can have different shapes and sizes depending on the design of the vehicle and the location of the lighting device.

[0036] The glass 2 comprises a side wall 6 extending perpendicularly or substantially perpendicularly to the front face 4 of the glass. The side wall 6 is intended to surround or be inserted into a housing of a lighting device of a motor vehicle, not shown in the figures.

[0037] In the present case, the side wall 6 shown in [Fig.l] is intended to extend parallel or substantially to one side of a motor vehicle. In other words, the side wall 6 is intended to be opposite a bumper skin extending over an edge of a motor vehicle.

[0038] Remarkably, the front face 4 of the window comprises an appendage 8 which extends beyond its side wall 6, so as to form a housing 10 intended to allow the insertion of an edge of a bumper skin, as described below.

[0039] Preferably, the appendage 8 extends beyond the side wall 6 of the ice by at least 2 cm, preferably by at least 5 cm, and the appendage extends along the entire length of the side wall 6 and possibly beyond said wall as illustrated in [Fig.l].

[0040] The appendage 8 forms with the side wall of the glass 2 an angle whose value is between 20° and 60°, preferably between 30° and 50°.

[0041] According to a remarkable characteristic of the invention, the ice 2 comprises several ribs 12 connecting its appendage 8 to the side wall 6. Preferably, each rib 12 is perpendicular or substantially perpendicular to the side wall of the ice and to its appendage. In other words, each rib 12 forms a table connecting the appendage of the ice to its side wall. The tables formed by the ribs are parallel to each other and preferably spaced apart by a distance of between 2 cm and 20 cm, or between 5 cm and 10 cm.

[0042] The invention also relates to a bumper skin 14 as illustrated in [Fig. 2]. The bumper skin is remarkable in that it comprises an edge 16 capable of being inserted into a housing 10 formed by an appendage 8 and a side wall 6 of the window illustrated in [Fig. 1].

[0043] According to the present example, the edge 16 of the bumper skin comprises several notches 18 arranged and sized to accommodate the ribs mentioned above, as illustrated by [Fig.3].

[0044] Thus, advantageously, the insertion of the ribs 12 into the notches 18 of the bumper skin 14 makes it possible to prevent the bumper skin from moving along the side wall 6 of the window.

[0045] Preferably, the notches 18 are sized so as to allow forcible insertion of the ribs 12 of the bumper skin 14.

[0046] According to another advantage, the appendage 8 of the glass extends above the edge 16 of the bumper skin, which makes it possible to prevent a phenomenon of accumulation of dirt at the junction between the appendage 8 and the bumper skin, in particular when the appendage extends on one side of a motor vehicle equipped with said glass, because the dirt will naturally tend to flow along the motor vehicle when it moves, without being hindered at the junction zone between the glass and the bumper skin.

[0047] According to an alternative embodiment of the invention illustrated by [Fig. 4], the edge 16 of the bumper skin comprises on its surface at least one lug 20 or finger, capable of guiding the insertion of the edge of the bumper skin into the housing 10 formed by the appendage and the side wall of a window described above.
