Description

Title of the invention: Sunshade System technical field

[0001] The invention relates to an improved sunshade system for motor vehicles. Previous technique

[0002] Folding "accordion-style" sunshade devices are known for their storage, when not in use, in a storage compartment, for example in a glove box or trunk, located inside the vehicle. Such sunshade devices can be deployed from their folded position so that, in their deployed form, they can be positioned opposite almost all or all of the inner surface of the windshield of a parked vehicle, thus forming a screen that reflects solar radiation. In this way, the deployed sunshade reflects at least some of the solar radiation directed at the windshield of the motor vehicle and significantly limits the heating of the vehicle's dashboard and passenger compartment.

[0003] Such a sunshade, however, has drawbacks. A folding, accordion-style sunshade is generally made of a material that exhibits a certain rigidity at a temperature of around 20°C and is sufficiently self-supporting to be positioned against the inner surface of the vehicle's windshield, thus remaining in contact with almost all or all of the inner surface of the windshield at this low temperature. However, when the vehicle and the sunshade are exposed to sunlight, the temperature of the sunshade increases and the rigidity of the material forming the sunshade decreases, causing the sunshade to lose its self-supporting properties and deform, reducing the area of ​​the windshield protected by the sunshade. The protection of the dashboard against solar radiation and overheating is no longer effectively ensured.

[0004] The invention aims to overcome this drawback.

[0005] Such a sunshade folded like an accordion has a bulkiness, in particular a length, which does not allow it to be stored in just any storage space in the vehicle.

[0006] The invention aims to overcome this drawback.

[0007] Furthermore, such accordion-folded sunshades may be stored, when not in use, in any storage compartment within the motor vehicle, and in particular in a storage compartment that remains inaccessible to the driver when seated in the driver's seat. It appears practical and advantageous for the sunshade to be readily available and accessible for the driver of the vehicle seated in the parked vehicle so as to allow the latter to deploy the sunshade from his seat, without having to get out of the vehicle to find the sunshade.

[0008] The invention aims to overcome this drawback.

[0009] In addition, such sunshades are likely to be stored away from the vehicle during the winter so that, upon returning from a period of strong sunshine, the sunshade is not available in the vehicle.

[0010] The invention aims to overcome this drawback.

[0011] Finally, such sun visors are not easily deployable with regard to the inner face of the windshield, so that their imperfect deployment leads to suboptimal protection against solar radiation.

[0012] The invention aims to overcome this drawback.

[0013] The invention therefore aims to provide a sunshade system for motor vehicles, the size of which is optimized when folded.

[0014] The invention also aims to provide such a sunshade system in which the deployment - in particular the deployment by the driver of the vehicle - of the sunshade is facilitated.

[0015] The invention also aims to provide such a sunshade system optimizing the protection of the parked vehicle against solar radiation.

[0016] The invention also aims to provide such a sunshade system that reduces fuel consumption allocated to vehicle cooling by optimizing the vehicle's protection against solar radiation. Description of the invention

[0017] To this end, the invention relates to a sunshade system comprising at least one element, called a sunshade, adapted to be able to extend in relation to at least a part of an inner face of a front windshield of a motor vehicle, in at least one first deployed state of said sunshade, and to reflect solar radiation, characterized in that the sunshade system forms a housing integral with the vehicle and adapted to be able to receive and contain said sunshade in at least one second folded state of said sunshade and to be able to allow extraction of said sunshade contained in the housing, and in that said sunshade is integral with the housing in each first deployed state of the sunshade and in each second folded state of the sunshade.

[0018] Throughout the text: - The terms "front", "rear", "right", "left", "up" and "down" are to be considered in relation to a motor vehicle in normal state of motion, - the XYZ coordinate system refers to a direct orthonormal XYZ coordinate system classically used in automotive design, in which the X-axis designates the forward longitudinal direction The rear of the motor vehicle, oriented from front (-X) to rear (+X), the Y-axis designates the transverse direction, oriented from left (-Y) to right (+Y) of the motor vehicle, and the Z-axis designates the vertical direction, oriented from bottom (-Z) to top (+Z) of the motor vehicle. Such a direct orthonormal XYZ coordinate system is schematically represented in [Fig. 10].

[0019] According to the invention, said sunshade of the sunshade system makes it possible to limit the heating of the dashboard and the interior space of a parked motor vehicle exposed to solar radiation, particularly during the summer period.

[0020] According to the invention, said sun visor is dimensioned to provide, in its first deployed state, for substantially all, in particular all, of the inner surface of the front windshield of the motor vehicle. All dimensions of said sun visor in its first deployed state are possible.

[0021] According to the invention, said sunshade has in the first deployed state of said sunshade, at least one main face - in particular two main faces - reflective of solar radiation.

[0022] According to the invention, said sun visor, in particular said sun visor in the first folded state, is accessible - in particular accessible to the driver - in each of the first and second folded or deployed states of said sun visor.

[0023] According to the invention, the housing forms a through-opening dimensioned to allow passage of said sunshade. The housing and the through-opening of the housing are configured to allow loading and storage of said sunshade in the housing, said sunshade being in its second folded state. However, the housing and the through-opening of the housing are configured to allow extraction or unloading of said sunshade stored in the housing, said sunshade being in its second folded state.

[0024] According to certain embodiments, the housing has two larger dimensions—in particular, a depth and a width—extending in two directions orthogonal to each other, and a smaller dimension—in particular, a thickness—extending in a direction orthogonal to the directions of the two larger dimensions. According to these embodiments, the opening of the housing is in the form of a slot extending across the entire width of the housing.

[0025] In certain embodiments, the system according to the invention comprises a guide plate for said sun visor moving relative to the housing, said guide plate supporting said sun visor and being slidably mounted in the housing, between a first position, referred to as the folding position, of said guide plate in which said guide plate and said sun visor in at least a second folded state extend into the housing—in particular, extend completely into the housing—and a second position, referred to as the deployment position, of said guide plate, in which said guide plate extends at least partly outside the housing.

[0026] Said guide plate may be made of any material that is rigid in tension and rigid in bending. A material that is rigid in tension and rigid in bending is understood to be a material that does not deform under the effect of its own weight plus the weight of said sun visor. However, said guide plate may be made of any material that is rigid in tension and flexible in bending. Said guide plate may also be made of any material that is rigid in tension and elastic in bending. Said guide plate may be elastically deformed in said folded position and elastically returned to an undeformed state in said unfolded position.

[0027] Said guide plate may be substantially flat. It may be flat. It may also have, along any longitudinal section in a plane orthogonal to the Y-axis of the direct orthonormal XYZ frame, a curved shape, concave downwards (along the Z-axis of the direct orthonormal XYZ frame). In certain embodiments, said elastic guide plate in bending may be deformed in said folded position of the guide plate and elastically returned to its curved shape in said unfolded position of the guide plate.

[0028] Said guide plate is dimensioned to be able to slide in the housing. But said guide plate is also dimensioned to be able to support said sun visor in at least one second folded state, and in such a way that said sun visor in at least one second folded state does not extend laterally beyond the edges of said guide plate.

[0029] According to some embodiments, said sun visor may be in the folded state in said deployment position of said guide plate. According to some other embodiments, advantageously said sun visor may be in the deployed state in said deployment position of said guide plate.

[0030] In some embodiments, the housing has means for guiding said guide plate as it slides within the housing. Any suitable guiding means to facilitate the sliding of said guide plate within the housing is possible. In some embodiments, the housing has lateral grooves for guiding said guide plate as it slides within the housing.

[0031] According to some of these embodiments, said guide plate in said folded position extends entirely into the housing. According to some other of these embodiments, said guide plate in said folded position may extend only partially, that is to say partially, into the housing, a portion of the front longitudinal end (along the X axis of the direct orthonormal XYZ frame) of said guide plate extending forward outside the housing.

[0032] In certain embodiments, said guide plate is a bending elastic plate, that is to say, elastically deformable in bending, at least in one principal dimension of said guide plate extending parallel to a guidance direction between said deployment position and said folding position. In certain embodiments, said guide plate is a bending elastically deformable plate at least in one principal dimension of said guide plate extending parallel to the X-axis of the right-handed orthonormal XYZ frame. In some of these embodiments, said guide plate in an elastically deformed state can be held in the housing and in said folding position by virtue of this elastically deformed state.Maintaining the guide plate in an elastically deformed state within the housing prevents uncontrolled and inappropriate release of the guide plate and sun visor from the housing. However, the guide plate can be elastically returned to an undeformed state in its deployed position.

[0033] In certain embodiments, the system according to the invention includes means for returning said guide plate to said folded position, said sun visor being in the second folded state of said sun visor. Returning said guide plate and said sun visor to the second folded state is thus facilitated.

[0034] In some embodiments, the means for returning said guide plate in the housing are elastic return means for said guide plate.

[0035] In some embodiments, the means for retracting said guide plate into the housing are adapted to retract said guide plate into the housing so that said guide plate extends fully into the housing. In some other embodiments, the means for retracting said guide plate into the housing are adapted to retract said guide plate into the housing so that said guide plate extends partially into the housing, with a front longitudinal end portion of said guide plate extending forward outside the housing. In these other embodiments, the front longitudinal end portion of said guide plate extending forward outside the housing may act as a sunshade.

[0036] In some embodiments, the means for returning said guide plate comprise at least one band made of at least one elastic material in tension, a first of two longitudinal ends of each band being mounted integrally to a rear bottom of an interior space of the housing, a second of two longitudinal ends of each band being mounted integrally to said guide plate.

[0037] In certain embodiments, the means for returning said guide plate comprise a single band made of at least one elastic material in traction. In some embodiments, the means for returning said guide plate comprise a plurality of bands made of at least one tensile elastic material, in particular two bands made of at least one tensile elastic material. Any tensile elastic material may be used for the manufacture of the tensile elastic band(s) provided that it is compatible with use in the automotive industry. It may be a textile material, a polymer material, or an elastomer.

[0038] In some embodiments, one of the two longitudinal ends of each strip is mounted securely to the rear base of an interior space of the housing by clamping. In some embodiments, the other of the two longitudinal ends of each strip is mounted securely to said guide plate by bonding, heat bonding, welding, etc. However, nothing prevents the other of the two longitudinal ends of each strip from being mounted securely to said guide plate by additional hook-and-loop fastening means.

[0039] In certain embodiments, said sunshade is formed of a screen made of at least one flexible and reflective material and of at least one wire stiffener closed in a loop on itself and mounted securely around the periphery of the flexible screen, the wire stiffener being rigid in longitudinal tension and elastic in bending so that a torsional movement imposed on two opposite ends of the wire stiffener of said sunshade in the first deployed state and bringing the wire stiffener into a conformation having a plurality of loops -in particular a figure-eight conformation having two loops-, followed by a folding of the loops over each other and opposite each other -in particular one over the other- maintains said sunshade in said second folded state.

[0040] In certain other embodiments, said sunshade is formed of a screen made of at least one flexible and reflective material, the flexible screen being in two parts joined together and foldable opposite each other, each foldable part comprising at least one wire stiffener closed in a loop on itself and mounted securely around the periphery of said foldable part, each wire stiffener being rigid in longitudinal tension and elastic in bending such that a torsional movement imposed on two opposite ends of each wire stiffener of said sunshade in the first deployed state and bringing each wire stiffener into a conformation having a plurality of loops -in particular a figure-eight conformation having two loops-, followed by a folding of the loops over each other -in particular one over the other- maintains said sunshade in said second folded state.

[0041] Folding and storing the sunshade in its folded state is facilitated. Deploying the sunshade from its folded state is spontaneous after the loops of the wire stiffener(s) have been deployed. Handling the sunshade system is easy and convenient.

[0042] In certain other embodiments, a first foldable flexible screen portion comprising a first wire stiffener forming said plurality of loops folded one on top of the other extends over a first main face of said guide plate, and a second foldable flexible screen portion comprising a second wire stiffener forming said plurality of loops folded one on top of the other extends over a second main face of said guide plate, opposite the first main face (in the folded state of said sunshade). The dimensions of said sunshade in the folded state are optimized, and its insertion into the housing is facilitated.

[0043] In some embodiments, the flexible screen may be a fabric or a film. Any other flexible material may be used provided that its structure and physical properties are not significantly and permanently altered by exposure to solar radiation. The flexible screen has at least one main reflective surface. The term "flexible screen" or "screen made of at least one flexible material" refers to a screen that is not self-supporting, that is, one that deforms spontaneously under its own weight and is therefore easily foldable and can be folded back on itself.

[0044] In these embodiments, the wire stiffening element is adapted to be able to keep deployed - in particular stretched in application - on the windshield of the vehicle, the part of the flexible screen with which it is mounted integrally.

[0045] In certain embodiments, the wire stiffener may be metallic. It may be a wire stiffener made of at least one polymer or composite material. It may be a wire stiffener comprising carbon fibers or formed from carbon fibers. Other types of wire stiffeners that are rigid in longitudinal tension and elastic in bending are usable provided they allow the sun visor to fold and remain in the second folded state as a result of this folding.

[0046] The invention also extends to a motor vehicle equipped with a sun visor system according to the invention.

[0047] In certain advantageous embodiments, the housing for the sun visor system is fixed to the vehicle. The sun visor is thus permanently attached to the vehicle, and the risks of loss or improper storage are limited or even eliminated.

[0048] In certain embodiments, the housing extends at least partially—in particular entirely—directly above a driver's seat in the vehicle. In these embodiments, the housing extends laterally (along the Y-axis of the XYZ coordinate system of the direct orthonormal frame) directly above a driver's seat in the vehicle. In these In embodiments, the housing extends longitudinally (along the X axis of the XYZ frame of the direct orthonormal frame) directly above a driver's seat of the vehicle.

[0049] In these embodiments, the sun visor, in its second folded state, is stored in the housing attached to the housing near the driver of the vehicle and is directly accessible to the driver. The risk of misplacing the sun visor is thus greatly reduced. Furthermore, the driver of a parked vehicle exposed to, or likely to be exposed to, intense sunlight can, while remaining seated, remove the sun visor from the housing by sliding the guide plate and deploy the sun visor to cover the entire inner surface of the windshield, extending downwards from the dashboard defroster and upwards to the rearview mirror and the adjustable front sun visors.

[0050] In certain embodiments, the housing is formed by a rigid or semi-rigid casing for receiving and storing said sun visor in at least one second folded state of said sun visor, the casing and the sun visor system being adapted to be mounted securely to the vehicle. In certain embodiments, the casing and the sun visor system are mounted securely to the vehicle. However, nothing prevents, in certain embodiments, providing a space within the vehicle to form the housing. Nothing prevents providing, for the purpose of forming the housing, a space extending from bottom to top (i.e., along the Z-axis of the direct orthonormal XYZ coordinate system) between a portion of the headliner forming the passenger compartment ceiling and a portion of the outer layer forming the vehicle roof.In some embodiments, the housing formed between the trim and the vehicle roof extends into at least a portion of the thickness of a layer of thermal and acoustic insulation interposed between the trim and the vehicle roof. In some embodiments, the casing forming the housing extends into at least a portion of the thickness of a layer of thermal and acoustic insulation interposed between the trim and the vehicle roof.

[0051] In certain embodiments, the housing extends / is interposed between a portion of the headliner—forming the ceiling of the vehicle's passenger compartment—and a portion of the outer layer forming the vehicle's roof. In these embodiments, the housing extends / is arranged within a thickness of the vehicle's passenger compartment ceiling. According to these embodiments, the sunshade contained within the housing is directly accessible to the vehicle's driver. According to these embodiments, the sunshade is not at risk of being trampled by a passing vehicle, and the sunshade's lifespan is increased. Furthermore, in these embodiments, the aesthetic appearance of the vehicle's passenger compartment is preserved, and the perceived quality for the vehicle user is satisfactorily ensured. The sunshade system is compact and extends into a space that does not affect the comfort of the driver and passengers of the vehicle.

[0052] In certain embodiments, the housing has an opening through which said sun visor passes in the second folded state of said sun visor, said opening being open in the front part -in particular on the front face- opposite a rear bottom of the housing, into a passenger compartment of the vehicle and oriented towards the front of the vehicle, parallel to the axis -X of the direct orthonormal XYZ frame.

[0053] In certain embodiments, the through-opening extends into the front part of the housing, the housing being arranged so that an upper edge of the through-opening of the housing abuts a front windshield seal of the vehicle. In these embodiments, the housing forms the passenger compartment ceiling of the vehicle and extends the passenger compartment ceiling forward to a rear / upper part of the windshield seal.

In the embodiment shown, the motor vehicle 40 is a left-hand drive (LHD) vehicle with the steering wheel 23 located to the left of the Y=0 plane as shown in Figure 10. Of course, nothing prevents the motor vehicle 40 from being a right-hand drive (RHD) vehicle with the steering wheel located to the right of the Y=0 plane as shown in Figure 10. The vehicle 40 according to the invention shown includes a windscreen 4 allowing the passenger compartment 26, the steering wheel 23 and a driver's seat 21 of the vehicle 40 to be seen through it, extending opposite the steering wheel 23. The vehicle 40 according to the invention is equipped with a sun visor system 1 arranged laterally (along the Y axis of the direct orthonormal XYZ frame shown in [Fig.10]) directly above the driver's seat 21.The sunshade system 1 comprises a housing 6 having an opening 24 at the front of the housing 6. The housing 6 is located within a thickness 22 of the internal ceiling of the vehicle 40. Neither the volume accessible to the driver and passengers of the vehicle, nor their comfort, is affected by the sunshade system 1 according to the invention. The sunshade system 1 is arranged longitudinally (along the X-axis of the direct orthonormal XYZ coordinate system shown in [Fig. 10]) towards the front such that the opening 24 of the housing 6 opens into the passenger compartment 26 of the vehicle 40 at the level of an upper edge of the windshield 4 and at the front part of the internal ceiling of the vehicle 40. According to certain embodiments, the opening 24 of the housing 6 opens into the passenger compartment 26 of the vehicle 40 at the level of a junction formed between the windshield 4 and an external layer 28 forming the roof of the vehicle 40.The housing 6 of the sun visor system 1 is adapted to receive and store a component, called the sun visor, in a second folded state of said sun visor, said sun visor being adapted to extend, in a first deployed state of said sun visor, opposite at least a portion of an inner face 3 of the front windscreen 4 and to reflect solar radiation. The housing 6 of the sun visor system 1 is also adapted to deliver said sun visor in such a way as to allow its deployment and the reflection of solar radiation.

The guide plate 8 of [Fig. 2] has, in any longitudinal section in a plane orthogonal to the Y-axis of the direct orthonormal XYZ coordinate system, a curved shape, concave downwards (along the Z-axis of the direct orthonormal XYZ coordinate system). This curved shape is advantageous for allowing the sun visor to be oriented substantially parallel to the windshield, taking into account the inclination of the windshield relative to the principal plane of the housing 6.The sunshade system 1 according to the invention includes means 11 for retaining the guide plate 8 in the housing 6. The retaining means 11 may be formed of two bands 12 made of at least one tensile-elastic material.
