Definitions

• the present invention relates to a dashboard for a vehicle such as, for example, motor vehicles, capable of allowing the diffusion of air flow in the passenger compartment of said vehicle.
• dashboards for motor vehicles are known, provided with orifices fitted with ventilation grids arranged laterally and in the central part.
• two are provided in the median part ⁇ and allow to directly project an air flow to the rear passengers between the two front seats.
• Two others are provided at the lateral ends of said dashboard and make it possible to project air flows directly laterally into the passenger compartment of the vehicle, that is to say either towards the front passengers, on the side of the vehicle doors. , or in the direction of the windows of said doors to ensure their defrosting and / or demisting.
• said air flows are generated by an aeration circuit comprising, for example, a blower and a network of 20 conduits, provided under the dashboard, said network opening onto said orifices.
• the ventilation grilles are generally orientable, for example in two planes, so as to leave passengers the possibility of adjusting the direction emission of air flows.
• said ventilation grilles are often the source of air flow tubing, thus constituting a source of noise, and this more particularly in high ventilation regime.
• the purpose of the present invention is to provide a dashboard for a vehicle which overcomes the aforementioned drawbacks and makes it possible to reduce the length of the ducts of the ventilation circuit of the passenger compartment of said vehicle so as to reduce the pressure losses in said circuit. .
• An advantage of the present invention is thus to reduce the power required as well as the temperature response time of the ventilation circuit of the passenger compartment of said vehicle.
• Another object of the present invention is to provide a dashboard for a vehicle, capable of allowing at least the lateral diffusion of an air flow in the passenger compartment of said vehicle, by which the noise generated by said diffusion is reduced.
• Another object of the present invention is to provide a dashboard for a vehicle, capable of allowing at least the lateral diffusion of an air flow in the passenger compartment of said vehicle, by which the adjustment of said flow is facilitated.
• Another object of the present invention is to provide a dashboard for a vehicle, capable of allowing at least the lateral diffusion of an air flow towards each of its lateral ends, thanks to which the balance said laterally distributed flows is ensured.
• Another object of the present invention is to provide a dashboard whose aesthetic appearance is improved.
• the invention relates to a dashboard for a vehicle, in particular a motor vehicle, having two lateral ends connected by a middle part, said dashboard being capable of allowing at least the lateral diffusion of an air flow in the passenger compartment of said vehicle. , characterized by the fact that it has:
• Figure 1 describes, schematically, in top view, a vehicle with a dashboard according to the invention.
• FIG. 2 describes, in top view, a particular example of a dashboard according to the invention.
• Figure 3 is a perspective view, more complete, of the example dashboard according to the invention shown in Figure 2.
• Figure 4 is a section, taken along the axis IV-IV shown in Figure 2, illustrating in a side view the example of a dashboard described in this same figure.
• the present invention relates to a dashboard for a vehicle, such as, for example, a motor vehicle, capable of allowing the diffusion of air flow in the passenger compartment of said vehicle.
• a vehicle 1 is observed, represented schematically, comprising, for example, a hood 2 and a passenger compartment 3 terminated by a trunk 4.
• said passenger compartment 3 comprises two front seats, distributed symmetrically on either side of the longitudinal axis 5 of the vehicle, constituting a driver's seat 6 and a passenger seat 7. At the rear, said passenger compartment 3 also includes a bench seat
• said passenger compartment 3 is provided with a dashboard 9 according to the invention.
• the latter is arranged, for example, transversely to said vehicle 1, in particular from one of its front doors to the other.
• vehicle 1 described above is only a non-limiting example of a vehicle in which the dashboard according to the invention can be used, other interior arrangements of the passenger compartment 3 of course possible.
• Said dashboard 9 has two lateral ends 10,
• said lateral ends 10, 11 are therefore those located opposite the lateral sides 13, 14 of said vehicle 1 and the middle part 12 is located, substantially, in the vicinity of the longitudinal axis 5 of the latter.
• said dashboard 9 is able to allow at least the lateral diffusion of an air flow in said passenger compartment 3 of vehicle 1.
• lateral diffusion mean that said air flow is directed into the passenger compartment 3, at least in the direction of the regions of said passenger compartment 3 located opposite said lateral ends 10, 11, that is to say say according the example illustrated, in the direction of the driver's and / or front passenger's sides facing the doors. Said air flow can also be directed towards said doors themselves, in particular so as to allow defrosting and / or demisting of their glazed surface.
• the dashboard 9 has an emission zone 15 of said laterally diffused air flow, offset towards said middle part 12.
• emission zone is meant zone at which the flow arrives at the outer surface of the dashboard 9, said outer surface being that which is opposite the passengers.
• Said emission zone 15 is therefore distant from the lateral ends 10, 11 and, in order to allow said laterally diffused flow to reach the regions described above, it cooperates with means 16 for externally guiding the flow of air emitted along said dashboard 9 and ensure its lateral distribution, as illustrated, for example, by the arrows marked 17, 18.
• outside it is meant that the air flow emitted in the emission zone 15 is guided, as developed below, on the outside surface of the dashboard 9. The latter therefore makes it possible to avoid the long lengths of ducts, provided under the dashboards previously known for conveying air into their emission zones, ci located near their lateral ends.
• the dashboard according to the invention thus makes it possible, in particular, to reduce the pressure drops and to improve the air diffusion.
• the emission zone 15 is provided, more precisely, at the level of the middle part 12 and has at least two orifices 19, 20, said to have lateral flow.
• the latter are respectively able to allow the diffusion of an air flow towards each of the lateral ends 10, 11 of the dashboard 9, for example according to said arrows marked 17, 18.
• the dashboard 9 is suitable for allowing, for example, in addition, the direct diffusion of an air flow in the passenger compartment 3 of the vehicle 1, in particular along the arrow marked 21.
• said emission zone 15 also has, for example, at least one additional orifice 22, said to be of direct flow, capable of allowing said direct diffusion, that is to say without prior guidance of the air flow emitted on the surface of the dashboard 9.
• said direct flow is oriented, in particular, towards the rear seat 8, between the two seats 6, 7 of the front passengers, substantially along the longitudinal axis 5 of vehicle 1.
• said lateral and / or direct air flows are generated, as already mentioned, for example, by a ventilation circuit provided under the external surface of the dashboard 9
• Said aeration circuit consists, in particular, of a blower and a network of conduits, not shown.
• the dashboard 9 therefore makes it possible to optimize said aeration circuit, all of the air flows, lateral and / or direct, being common and opening into a single emission zone 15 to then be diffused separately in the passenger compartment 3 according to their respective direction.
• the length of the network of conduits and the resulting pressure losses as well as the response time of the temperature aeration circuit are thus advantageously reduced.
• said emission zone 15 is made up, in particular, of a protrusion 23, having said lateral flow orifices 19, 20, on each of its lateral faces 24, 25 and said flow orifices direct 22 on its front face 26.
• lateral face 24, 25 is meant the face of the protrusion 23, substantially orthogonal to the outer surface of the dashboard 9.
• frontal face 26 is meant the face of the protrusion 23 oriented substantially parallel to said outer surface of the dashboard 9.
• said prominence 23 constitutes, for example, a column, oriented substantially vertically.
• the protrusion 23 may possibly have edges 27 capable of masking said lateral flow orifices 19, 20.
• said lateral flow orifices 19, 20 as well as the direct flow orifice 22 are provided, in particular, with ventilation grids 33.
• the means 16 for freely guiding the laterally diffused air stream (s) consist, for example, of recesses 28, 29 having a given curvature, provided between said emission zone 15 and said lateral ends 10, 11. Said recesses 28, 29 form, in particular, deflectors.
• said lateral flow orifices are oriented, in particular, towards the front quarter of the passenger compartment 3 of the vehicle 1 and thus cooperate with the recesses 28, 29 at their end provided on the side of the emission zone 15.
• said recesses 28, 29 comprise, for example, a first region 30, substantially planar, slightly inclined, in particular with respect to the horizontal, and a second region 31, defining a curved surface along the dashboard 9 in a substantially elliptical manner, extending the first towards the upper end of said dashboard 9, according to a rounded profile. They therefore have, for example, a form of scoop.
• Said laterally diffused air flows are thus guided along said recesses 28, 29 and directed towards the interior of the passenger compartment 3, for example, in a direction substantially tangent to the orientation of the ends of said recesses 28, 29 provided for side of the lateral ends 10, 11 of the dashboard 9, in particular, as mentioned above, towards the sides of the driver and of the front passenger facing the doors of the vehicle 1 and / or towards the glazed surfaces of said doors .
• the dashboard 9 has, possibly, integrated elements whose external contours participate in the definition of said recesses 28, 29. These are, for example, the hood of an airbag for the recess located on the passenger side or, for the recess located on the driver's side, there visor and the glass of the instrumentation box 32. In the case where said instrumentation box is attached, it is then the top of the dashboard 9 which can, for example, have the shape of a scoop.
• said dashboard optionally further includes means for adjusting the flow rate of the emitted air flow (s). It is, for example, a device for controlling the characteristics of the ventilation circuit, in particular accessible on the exterior surface of said dashboard
• Said characteristics of the ventilation circuit consist, for example, of the air flow generated by the blower and / or by the position of one or more valves closing more or less the network of conduits of said circuit.
• the means for adjusting the flow rate thus make it possible to obtain, for example, either a gentle diffusion when the latter is low, or a significant deflection of the air flow, in particular for demisting, when it is higher.
• the direction of the air stream or streams diffused laterally is invariable. The occupants of vehicle 1 are thus freed from the delicate and tedious adjustment of the orientation of the air flow, which allows, in particular the driver, not to be distracted and to devote himself entirely to traffic.
• the present invention relates both to tables made of a solid material having reservations for the various on-board instruments and to dashboards made of a panel through which the said instruments open.
