The invention relates to the field of motor vehicles, more particularly to vehicles equipped with a head-up display device. More particularly, the invention relates to the attachment of such an apparatus to the structure or body of the vehicle.

A head-up display device, commonly designated by the acronym HUD for the English expression "Head-Up Display", is to project information on the windshield of the vehicle. Such an apparatus is usually located behind the dashboard, that is to say between the dashboard and the upper rail above the deck, and projects with the help of diodes information on the windshield, the driver having the illusion that the latter are a few meters ahead of him. The projected information is usually selected from among the most important information such as vehicle speed and instructions of a navigation system.

These devices are experiencing developments of providing augmented reality, including superimposing on the windshield a virtual route highlighted on the real road that the driver must follow. This makes it possible to make the information provided by the navigation system much more precise. They include several mirrors adapted to the shape of each windshield so that the projection of the image is clear. They are therefore heavier and bulky and can sometimes not be fixed directly to the dashboard.

Figures 1 and 2 illustrate a first embodiment of the invention. They illustrate a portion of the vehicle body, corresponding to the front part of the passenger compartment of the vehicle.

The vehicle body portion 2 comprises a front apron 4 forming a separation between the passenger compartment and the engine compartment. It also comprises a central tunnel portion 6 connected to the deck 4. It also comprises a front cross member 8 located above the deck 4.

Referring to Figure 1, a head-up display apparatus 10 is attached to the body 2 of the vehicle. This apparatus consists essentially of a housing containing electronic and optical components capable of projecting images containing information essentially relating to the driving of the vehicle towards the windscreen. Such an apparatus is well known to those skilled in the art. It can be used to project information in the form of numbers and / or signs in a predefined area of the driver's field of vision. It can also be designed to project information, essentially graphical, superimposed on the road landscape to increase their reality. By way of example, it may be a graphic marking of a rolling band to be used on a road that has several roads. Such a device can then be electrically connected to a camera and / or radar analyzing the road and traffic.

With reference to FIGS. 1 and 2, the head-up display apparatus 10 is fixed to the body 2 by means of a fixing device 12 comprising two upper supports 14 (only one of which is visible in FIG. 1) and one lower support 16.

The upper supports form arms each connecting one of the side faces 101 of the housing to the upper cross member 8. Each of these supports 14 may be formed by stamping a sheet metal member. They may have a U-shaped section with a generally vertical core, when in mounting position on the vehicle body, and two soles. The core may have a length of between 20 and 80mm. The soles may have a length of between 5 and 30mm. Each of the upper supports 14 may comprise, at one end, a tab 141 for attachment to one of the side faces 101 and 102 of the housing. These tabs 141 are advantageously in the plane of the support core. Each of the upper supports 14 may comprise, at a second end, a tab 142 for attachment to the upper rail 8. These tabs 142 are preferably perpendicular to the core of the corresponding support. They are fixed to generally horizontal attachment areas of the crossbar 8 in question. Each of the tabs 141 and 142 advantageously comprises one, preferably at least two fixing holes.

The lower support 16 extends inclined downwardly from a lower face of the housing. It can be formed essentially of a sheet metal element. It comprises an upper edge 161 (FIG. 2) with fixing means on the lower face of the housing. These fixing means may comprise orifices intended to receive fastening screws to the housing. The lower support 16 also includes one or more lower edges 162 provided with fastening means adapted to cooperate with the fastening means 18 of the crankset. The latter is not shown in Figures 1 and 2. The apron 4 has an orifice 41 located at the pedal and for transmitting the movement of the brake pedal of the pedal to a brake amplifier coupled to a control device of braking located in the engine compartment. The apron 4 comprises in this case four orifices 18 around the orifice 41 and intended for fixing the pedal. The two upper orifices 18 serve for positioning and fixing the lower support 16. The apron 4 may comprise a second orifice 42, near the first orifice 41. Similarly, the lower support 16 may also be fixed to the apron 4 in the vicinity of the second port 42, for example by means of screws or studs 20 fixed to the apron 4. The use of fastening means of one or more components on the apron for fixing the head-up display apparatus is interesting in that that this makes it possible to achieve precise positioning of the apparatus with respect to the windshield. Indeed, the latter is deposited on the vehicle body, especially on the upper rail 8. Or the latter is directly attached to the deck 4. The fastening means of the components on the deck 4, like the pedal, have a precise positioning on apron. Using them for positioning and fixing the device is therefore particularly interesting.

Figures 3 and 4 illustrate a second embodiment of the invention. The reference numerals of the first embodiment (FIGS. 1 and 2) are used to designate identical or corresponding elements, these numbers however being increased by 100. Reference is also made to the description of these elements in relation to the first embodiment. Specific numbers between 100 and 200 are used to designate elements specific to this embodiment.

The second embodiment is quite similar to the first embodiment. It differs essentially in the shape of the supports of the fixing device of the head-up display apparatus. In FIG. 3 it can be observed that the head-up display apparatus 110 is fixed to the body 102 by a fixing device 112 comprising, similarly to the first embodiment, two upper supports 114 and a lower support 116. also observe that a beam 122 intended in particular to serve as a support for the steering column (not shown) is disposed transversely to the vehicle, behind the upper cross member 108. It is observed that the housing of the head-up display apparatus 110 comprises on its rear face a recess intended to receive the beam 122. The apparatus in question is advantageously free of direct attachment to the beam 122. In other words, the beam 122 is fixed to the body 102, in particular at its ends. , and the apparatus 110 is fixed to the body 102 independently of the beam 122. Still in Figure 1, it can be seen that the pedal 124 is shown there.

FIG. 4 illustrates in more detail the apparatus 110, its fixing device 112 and the manner in which the lower support 116 cooperates with the crankset 124. The lower support 116 is somewhat different from that of the first embodiment, in particular by the presence of gussets 1163, but still incorporates the principle, namely to be generally extended, in this case to be made in the form of a stamped, and to include an upper edge 1161 attached to a face and / or a lower edge of the housing of the apparatus 110 and a lower edge 1162 fixed to the deck at the fastening screw of the crankset 124. It can be observed that the crankset 124 comprises a brake pedal 1241 and a gas pedal 1242 both mounted on a support 1243. The latter can also consist of two parts, one for the brake pedal and the other for the gas pedal, these two parts being able to be fixed one to the other. It can be seen that the support 1243 has a recess 1244 intended to face the corresponding orifice in the apron 104, this recess and this opening being intended to receive a rod (not shown) for transmitting the movement of the brake pedal to a brake control device (not shown) attached to the apron in the engine compartment. It can also be observed that the lower edge 1162 of the lower support 116 has a contour surrounding the upper part of the support 1243 of the crankset 124. This edge 1162 also partially overlaps with a mounting plate of the support 1243 in question. occurrence at the upper openings 118 fixing the crankset 124 apron.

Still in relation to FIG. 4, it can be seen that the lower support can be easily put in place during the attachment of the crankset. The head-up display apparatus 110 may then be put in place and attached to the lower support 116 and then to the upper supports 114. This also applies to the first embodiment.
