Description

Description Sunshield for use with a vehicle windshield

Technical field

The invention relates to sunshields for applying onto the windshield in the interior of a parked motor vehicle.

Related art

Interiors of motor vehicles may essentially heat up due to exposure to intense sunlight. As the largest portion of heat energy is developed from sunlight radiation passing through the glass windshield, sunshields or alternatively sunshades may be applied onto or under the windshield respectively from outside or inside the motor vehicle by its owner every time the car is parked on a free space.

Existing sunshields for windshields are divided into two main families, the custom-made sunshields and the standard sunshields. The custom-made sunshields are provided in a broad variety of shapes to match with the different sizes and shapes of the vehicle windshields. However, shapes are not optimized so that one type of sunshield can provide a reasonable coverage of the windshield and shading of the vehicle interior only for a limited number of different car types. This is disadvantageous since on one hand the different sizes have to be manufactured in different batches so that advantages of scale economics cannot be fully used and the manufacturing costs are relatively high. On the other hand, due to the variety of different types of sunshields selection of the matching type of sunshield on sale by the end customer is more complicated. Meanwhile, standard sunshields which can be used for a broader variety of vehicle types are not better. Firstly, they cannot provide a reasonable shading coverage of the vehicle windshield for all vehicle types.

Secondly, they cannot be mounted in a straightened position against every windshield without extra fixing means such as suction cups, lanyards and the like because their shapes are not optimized to fit all shapes and sizes of windshields. Thirdly, fixing means are exposed to sunlight and might be subject to deterioration and aging which reduces lifetime of such sunshields.

It is therefore an object to provide for use on a vehicle windshield a sunshield with a shape which matches to a broad variety of windshield sizes and shapes with a high shading coverage so that by a set of a smaller number of different sizes of sunshields, most sizes and shapes of vehicle windshields can be covered.

It is a further object to provide a simplified solution based only on shape without any complex parts or expensive manufacturing operations.

Furthermore, it is an object to provide sunshields with a higher reliability which can be mounted without any extra fixing accessories.

It is also an object to provide a one size sunshield free from fixing accessories that can be easily mounted/installed in a straightened position onto a dashboard against the inner surface of a windshield.

It is an object to provide a one size sunshield that ensure a high shading coverage for windshields.

It is an object to provide a one size sunshield that ensure a compensation of shading when the size of the windshield on which it is installed varies from one to another.

It is an object to provide the sunshield with surplus areas which can be easily housed beside the windshield when the sunshield size is larger than the size of the windshield Summary of the invention

The above and further objects have been achieved by the sunshield for applying with a windshield of a motor vehicle according to claim 1 and to the set of sunshields and the arrangement of a sunshield to a windshield of a motor vehicle according to the further independent claims.

Further embodiments are indicated in the depending subclaims.

According to a first aspect a sunshield for applying onto a windshield in the interior of a motor vehicle is provided, including a substantially plane sunshield material having a top edge, opposing side edges and a bottom edge opposing the top edge, wherein the plane sunshield material has a shape defined by:

- a rectangular main body with an upper border, a lower border opposing the upper border, and two lateral borders opposing each other;

a cut-out in the upper border, particularly in the center of the upper border for accommodating a rear-view mirror holder.

Furthermore, one or two first extensions may perpendicularly protrude from at least a part of the upper border on one or both sides of the cut-out parallel to the lateral borders, respectively, to define the top edge of the sunshield, wherein the top edge at least partly incline towards the respective lateral border.

The idea of the above sunshield is to provide it in a shape that allows a better matching to the shapes and sizes of windshields of various motor vehicles. This is achieved by adding to the rectangular main body some surplus areas that are mounted at the windshield on its left, right, and up under the roof when the size of the main body matches the windshield. Furthermore, the sunshield may be used to compensate the gaps created/existing between the windshield and the rectangular main body when the size of the main body is too small to cover the windshield.

It may be provided that the one or two first extensions may have a shape with a maximum height with respect to the lowest level of the bottom edge/sunshield which is distanced from the rightmost or leftmost level of the side edges/sunshield respectively, by 0% to 25%, particularly by 0% to 18%, preferably by 5% to 15% of the total width of the sunshield. The one or two first extensions may be such that the height between the top edge of the sunshield and the lowest level of the bottom edge has its highest value(s) only in portions of the top edge located in a region of 0% - 25%, particularly in a region of 0% -18%, preferably in a region of 5% - 15%of the total width of the sunshield measured in a width direction from the rightmost or leftmost level of the side edges of the sunshield.

There are two main regions in/beside the windshield which cannot house any surplus areas of the sunshield: This is firstly the region of the top edge of the windshield located between about -20% and about +20% of the total width of the top edge of the windshield measured from the vertical center line of the windshield, and secondly, the regions of the side edges of the windshield located between 0% and about25% of the total height of the windshield measured from the bottom edge of the windshield.

Thus, the shape of the sunshield is the rectangular main body to which are added surplus areas not opposing the regions described above.

When the sunshield is mounted/installed under a windshield which size matches the main

I

body, the one or more first extensions are surplus areas which can easily be housed above the windshield towards the roof. When the sunshield is mounted/installed under a windshield higher than the maim body, the one or more first extensions are surplus areaswhich insure more cover of the windshield on its higher areas.

The one or more first extensions may comprise a mainly increasing height of the sunshield (with respect to the lower border) in regions sufficiently far from the center of the top edge. In other words, the one or more first extensions may particularly provide the sunshield at its top edge with an increasing/increased height with respect to the lowest level of the sunshield mainly in areas adjacent/close to the lateral borders.

It may be provided that the one or two first extensions extending sidewardly towards an extension of the respective lateral border, so that one or two first extensions have a triangular shape.

The extensions to the main body of the sunshield may include at least one of first extensions protruding from the upper border of the main body laterally displaced from the center cut-out. The first extension has the main advantage to allow the sunshield to compensate for a variation of height of the windshield so that the sunshield can also fit higher windshields not matching the main body without compromising its ability to fit the windshield with the smallest height matching the main body. Consequently, different heights of windshields can be covered by a single size of the sunshield.

The first extensions allow also to easily fasten the sunshield (when deployed inside the vehicle onto the dashboard) against high windshields which otherwise would not stay in place when the flapped down integrated sunvisors do not fixate the top edge of the sunshield. The first extensions allow the fixation of the sunshield by simply flapping the fixedly integrated sunvisors of the vehicle down so that the highest portions of the first extensions of the sunshield are trapped and clamped against the inner surface of the windshield. Hence, no further mounting means such as suction cups, lanyards and the like are necessary to mount/install the sunshield.

Particularly, the upper border of the main body may form a top edge of the sunshield.

According to an embodiment the lateral borders may form side edges of the sunshield.

According to an alternative embodiment, one or two third extensions may protrude from one or both lateral borders, respectively, forming the side edges, wherein the one or two third extensions at least partly provide a tapered contour of the respective side edges of the sunshield towards the bottom edge and/or towards the top edge of the sunshield, wherein particularly at least one of the one or two third extensions has a triangular or polygon or convex or concave shape with an apex at an upper corner between the top edge and the respective side edge, or with an apex at a lower corner between the bottom edge and the respective side edge, or with an apex at a position between the upper and lower corners particularly between 55% and 95%, preferably 20% and 45%, more preferably between 25 and 45%, most preferably between 30% and 95% of the total height of the sunshield.

Particularly, the one or two third extensions have a lateral apex at a height which ratio with respect to the total width of the sunshield is at least 16%, particularly at least 16,8%, preferably at least 17%, most preferably at least 17,5%. Particularly the one or two third extensions have a lateral apex at a height of at least 20cm, preferably at least 22 cm, most preferably at least 24cm from the lowest level of the bottom edge of the sunshield.

Particularly, one or more of the apices may have a rounded contour.

When the sunshield is mounted/installed at a windshield which has a width corresponding to the width of the main body, the one or more third extensions are surplus areas which can easily be housed beside the windshield on its left and on its right.

It may be provided that the one or two third extensions increase width of the sunshield in one or more parts sufficiently far from the bottom edge of the sunshield.

When the sunshield is mounted/installed at a windshield which has a larger width than the width of the main body, the one or more third extensions are surplus areas which insure more cover of the windshield on its left and right areas.

It may be provided that the one or two third extensions at least partly provide a tapered contour of the side edges of the sunshield towards the bottom edge in at least the lower part of the sunshield located between 0% and 40%, particularly between 0% and 50% of the total height of the sunshield measured from the lowest level of the sunshield.

It may be provided that the one or two third extensions at least partly provide a concave contour, with respect to the sunshield, of the side edges of the sunshield in the lower part of the sunshield located between 0% and 70%, particularly between 0% and 50%, preferably between 0% and 40% of the total height of the sunshield measured from the bottom edge of the sunshield. Particularly, the concave contour is partly widening in direction of the top edge of the sunshield and/or partly parallel to the vertical center line and usually not widening in direction of the bottom edge.

It may be provided that the one or two third extensions provide a surplus of material which allows the sunshield to compensate for a variation of width of the windshield so that the sunshield can also fit larger width windshields without compromising its ability to fit the smallest width windshields matching with the main body. Consequently, different widths of windshields can be covered by a single size of the sunshield. Top edges of the one or two third extensions forming a portion of the top edge of the sunshield may be parallel to the upper border of the main body, inclining towards the side edge of the sunshield or declining towards the side edge of the sunshield.

Furthermore, the one or two third extension(s) may have a shape which extends beyond the line defined by the upper border of the main body to the top edge of the sunshield.

The lower border may form a bottom edge of the sunshield.

According to an alternative embodiment, a second extension may protrude from the lower border, particularly with a convex contour, and form a bottom edge of the sunshield. The second extension may have to be shaped with a curved edge to make the sunshield convex on its bottom edge so that the sunshield can be more closely fitted to the bottom edge of the curved windshield. Consequently, the shading coverage is improved and a better support of the sunshield against the dashboard can be achieved.

It may be provided that the convex contour of the second extension is shaped as a circular segment or as an elliptical segment.

Moreover, the one or more first and/or second and/or third extensions and the main body may be integrally formed.

First, second and/or third folding lines may be respectively provided between the main body and at least one of the first, a second and a third extension, respectively.

Additional first, second, and/or third folding lines may respectively be provided through one or more of the first, second and third extensions, wherein the additional first folding lines in the first extensions are parallel to the upper border of the main body or parallel to the top edge of the sunshield, and/or wherein the additional second folding lines in the second extension are parallel to the lower border of the main body, and/or wherein the additional third folding lines in one or two of the third extensions are parallel to the respective lateral border of the main body or parallel to the side edge of the sunshield, wherein particularly the folding lines correspond to weakened parts of material of the sunshield or perforated lines or partially cut lines. Furthermore, a plurality of transport folding lines may be arranged through the sunshield parallel to the lateral borders of the main body in order to enable the sunshield to be easily folded in a proper transport state. The folding lines allow the sunshield to have folds and be in the form of accordion and when the folds are partially open/unfolded then the sunshield is able to have a width smaller than its overall width and be deployed in a small width windshield. For some sunshield materials that contain closed cells such as PE bubble or PE foam these folding lines are made in a manner that generates folding defects because of gas trapped in the closed cells and cannot release. Perforations or/and partial cuts may be arranged (particularly with weakening or thinning) along at least one of the folding lines in order to allow the release of the gas trapped in the closed cells therein and obtain at least one proper straight folding line. Furthermore, perforations or/and partial cuts may be arranged (particularly with weakening or thinning) along at least one folding line having any direction through the sunshield in order to obtain at least one proper straight folding line.

Furthermore, a plurality of transport folding lines may be arranged through the sunshield in any direction in order to enable the sunshield to be easily folded in a proper transport state. Particularly, perforations or/and partial cuts may be arranged (particularly with weakening or thinning) along at least one of the folding line (having any direction) in order to obtain at least one proper straight folding line.

At an upper end and/or at a lower end of at least one of the transport folding lines at least one notch may be provided, wherein particularly a portion of the at least one notch has a half-circular or triangular or polynomial shape or any kind of shape different there from. The notches improve matching and make easier the installation of the sunshield having transport folding lines and particularly made of rigid material such as cardboard and cellular plastic. If the (rigid made) sunshield is mounted at a windshield and when the sunshield is not fully unfolded, the notches insure that contacts between the ends of folding lines of the sunshield and the car dashboard occur without cumbersome sharp angles. The notches thereby facilitate the unfolding/opening of the sunshield folds and the sliding of the bottom edge of the sunshield along the dashboard. The installation of the sunshield is easier.

The notches facilitate a partial unfolding of a sunshield in place under a windshield which allows a wide sunshield to be installed under/at a windshield with a smaller width. In the same sunshield, notches may have different shapes and/or different sizes. For a sunshield mounted between a windshield and a dashboard, the difference in size of notches allows to further (foster) folding in some places more than others. The larger the notch the more the folding is favored. For example, wide central notches and small notches at the sides allow to have the central parts more folded than the others (when the sunshield is in mounted position).

Moreover, for any of the herein described sunshields, areas of weakened material or areas defined by weakened lines may be provided so as to obtain the notches by removing a portion of the sunshield material along the areas of weakened sunshield material. The weakened material can be formed by weakening or perforations or partial cuts.

Moreover, for any of the herein described sunshields a line of weakened material may extend throughout the sunshield parallel to at least one of the top, lateral and/or bottom edges of the sunshield so that sunshield material can be separated/removed by the consumer before use of the sunshield to produce a sunshield with smaller height and/or smaller width.

Alternatively, a wire or thread may be incorporated or attached on the sunshield material extending throughout the sunshield parallel to at least one of the top, lateral and/or bottom edges of the sunshield, so that by pulling off the wire or thread the sunshield material is cut in/off.

At or close to the corners between the bottom edge and a respective one of the side edges one or more cut-ins extending from the bottom edge and/or the respective side edge into the sunshield may be provided, wherein particularly the cut-ins have a longitudinal shape a width to length ratio of between 1 :2 and 1 :10, preferably 1 :5. The cut- ins can be formed by perforations or partial cuts.

When the sunshield is used onto/under a windshield having a small width, the portion with the cut-ins will be in contact with regions close/beside the lower parts of the side edges of the windshield where extra material of the sunshield is not allowed. Cut-ins extending from the bottom edge remove this geometric constrains and enable the sunshield used onto a windshield with a smaller width to easily fold up in this region. The segment which remains joined to the bottom edge goes between the dashboard and the windshield. The segment(s) which remains joined to the side edge fold up and easily lodges onto the dashboard and/or beside the windshield toward its left and/or right side edges.

Corners between the bottom edge and a respective one of the side edges may be cut off with a concave profile with respect to the sunshield, wherein particularly the concave profile has a rounded or curved or polygon contour, wherein particularly the cut-off has a width in direction of the lower border which is 0-20%, preferably 0-10% of the total width of the sunshield, wherein particularly the cut-off has a height in direction of the lateral border which is 0-70%, preferably 0-50%, most preferably 0-40% of the total width of the sunshield. Particularly, the concave profile is partly widening in direction to the top edge of the sunshield and/or at least partly parallel to the vertical center line. The aim of these cut off is to remove the geometric constrains between lower lateral corners and the neighborhood of lower parts of side edges of the windshield. The cut-offs can be defined or made by weakened material, perforations or partial cuts.

Furthermore, corners between two neighboring edges are rounded, particularly with a radius of less than 10% of the width of the sunshield.

It may be provided that reas of weakened material are provided so as to obtain the cut-out by removing a portion of the sunshield material along the areas of weakened sunshield material.

Furthermore, fixation means may be provided to hold the sunshield on a sunvisor blade, wherein particularly the fixation means includes an attachment area extending along the top edge of the sunshield and having a Velcro and/or magnetic characteristic and/or a clip to clamp the sunshield at the sunvisor blade.

According to a further aspect, a set of above mentioned sunshields is provided, wherein the set includes at least two sunshields having different widths of the main body and/or different heights of the main body.

Description of embodiments Figure 1 shows a cross-sectional view through a vehicle 1 with an interior 2 to accommodate passengers. A dashboard 3 including instruments is provided on a front part of the interior 2. Between the dashboard 3 and a roof 4 of the vehicle , a glass windshield 5 is provided which forms a windshield.

Substantially in the center of the width of the vehicle 1 , a rear-view mirror 6 is attached on an upper portion of the windshield 5 by means of a rear-view mirror holder 61. On both sides of the rear-view mirror 6, pivoting sunvisors 7 are attached on a front portion of the roof 4 which are hinged so that they can be flapped from a first position P1 where sunvisor blades 71 extend along the roof 4 and into a second position P2 where they are flapped into a front direction so that the sunvisor blades 71 are lying against or are close to a respective upper portion of the windshield 5.

An exemplary sunshield 10 is positioned on/under (or against) an interior surface of the windshield 5 to block and/or to reflect sunlight passing through the windshield 5.

As can be seen in Figure 2, usually, the windshield 5 is substantially plane/thin and has a curvature along the width of the vehicle which is concave with respect to the exterior of the vehicle 1. Flattened to a plane, different shapes of windshields are known and may differ in dimension independently. Particularly, a variety of different windshield shapes of similar sizes can be seen in the first row of Figure 2.

As the sunshield 10 shall be mounted in a position so as to cover most of the area of the windshield 5 and to be arranged as closely as possible to the windshield 5 in the interior of the vehicle 1 , the sunshield 10 needs to have a shape which comes close to the plane of the windshield 5 projected/flattened to a planar surface.

Standard sunshields have a substantially rectangular or trapezoidal shape with a respective cut-out 15 for receiving the rear-view mirror holder 61. It can be seen in the second and third rows for exemplary sunshields 10 with a rectangular and trapezoidal shape, respectively, that the respective sunshields 10 only match with the leftmost type of windshield, while they do not fit windshields with the other shapes.

To better fit into various spaces between the dashboard 3 and the roof 4, the sunshield 10 may be provided with an adapted geometrical shape. An exemplary geometrical shape is best explained as extensions to a rectangular main body as it is shown in conjunction with Figure 3.

Figure 3 schematically shows the sunshield 10 with a main body 11 substantially formed by a rectangular sheet of a sunshield material having an upper border 12, a lower border 3 which is opposite to the upper border 12, and two lateral borders 14 opposite to each other. Border in the present context means a virtual side of the main body 11.

The upper border 12 may be provided with a cut-out 15 in which the rear-view mirror holder 61 of the rear-view mirror 6 can be accommodated when the sunshield 10 is mounted on/against the inner surface of the windshield 5. The size of the main body 11 is selected so that it might fit a given minimum size of a windshield, i.e. a windshield which has the smallest height and the smallest width to which the sunshield 10 shall fit or can be applied.

The cut-out 15 can be formed by a weakened area of sunshield material or can be defined by perforations or partially cut line so that sunshield material can be separated/removed before use of the sunshield to form the cut-out 15.

The cut-out 15 may be preferably located in the center of the upper border 12. However, in further embodiments the cut-out 15 can be displaced from the center position at the upper border, particularly up to 20 % of the overall width of the upper border. The main body 11 may be provided with extensions to adapt to the shapes and sizes of different types of windshields.

The sunshield material may be made of a soft, but form-stable material, so that it can be easily bent to adapt to the curvature of the windshield while being stable enough to be attached between the dashboard and the roof of the vehicle 1.

The sunshield material might include a carrier material which can include or be made of any kind of slightly bendable material such as a composite cellular foam, polyethylene, polyurethane, polystyrene, cardboard, paper, textile, aluminum, metal or nylon or any kind of composite materials based thereon or any kind of insulating or reflective material. Particularly, the surface of the sunshield which shall be directed to the sunlight can be covered by a reflecting layer, such as aluminum, to reflect the sunlight back to the environment of the vehicle.

The main body 11 is provided with a first extension 20.

One or more first extensions 20 may be attached to the upper border 12 of the main body 11 and may protrude from at least a part of an upper border portion 12' of the upper border 12 defined between a vertical center line A of the upper border 12 or a side of the cut-out 15 and the respective lateral border 14. At least one first extension 20 might be applied on one of the upper border sides 12' or at least two first extensions 20 may be applied on both upper border sides 12'. Substantially, a part of a top edge 21 of the sunshield 10 formed by one of the first extension 20 extends linearly inclining from a side of the cut-out 15 or from the vertical center line A of the upper border 12 to a high point H1 which has the largest vertical distance from the lower border 13 of the main body 11 and in the present embodiment is vertically in line with the respective lateral border 14 of the main body 11. Therefore, a possible shape of the one or the two first extensions 20 forms a triangle, respectively.

The triangular shape of the first extension 20 which leads to an increasing height of the sunshield 10 towards the lateral sides thereof has an advantage as can be seen from Figures 4a and 4b. While a standard conventional rectangular sunshield, as shown in Figure 4a is only partly held by a folded-down sunvisor blade 71 , a gap is formed between a fixedly installed sun visor and the top edge of the standard sunshield through which sunlight can cross into the interior 2 and which does not ensure the attachment of such a standard sunshield at the windshield 5. A mere rectangular sunshield would require an additional fixing accessory.

Figure 4b shows how the first extension(s) 20 helps closing the gap and efficiently blocks sunlight from falling into the interior 2 over the length of the fixedly installed sun visors 7. Furthermore, the contact area between the top edge of the sunshield 0 and the sunvisor blades 71 flapped into the second position P2 is larger which improves and ensures holding of the sunshield 10. No additional fixing accessory would be required to mount the sunshield 10. The surplus of material provided by the first extension(s) 20 can be easily housed between the roof 4 and the sun visor blades 71 flapped into the second position P2 or under the sunvisor blades 71 placed in the first position Plwhen the sunshield is used for a windshield (with small height) which height matches the main body

However, other shapes of the first extension 20, such as circular shapes, elliptical shapes, square shapes or the like might be applicable as well. The shapes may also form a sunshield with a top edge with a concave or convex shape. Instead of the height point H1 , there may be a line segment of maximum height. It may be provided that the height point H1 or the line segment of maximum height (if there is one) is in a region located between 0% and 25%, particularly between 0% and 18%, preferably between 0% and 15%, most preferably between 5% and 15%of the total width of the sunshield 10 measured from one or both of the rightmost and leftmost level of the side edges of the sunshield 10 formed by the first extension 20. Alternatively, it may be provided that the height point H1 is in a region located between 25% and 50%, particularly between 32% and 50%, preferably between 35% and 50%, most preferably between 35% and 45% of the total width of the sunshield 10 measured from the vertical center line A (parallel to the lateral borders 14).

The first extension 20 may be attached to the main body 1 1 or integrally formed therewith. A first folding line F1 may be applied between the first extension 20 and the main body 11. The first folding line F1 may weaken the first extension 20 during installation of the sunshield 10 so that the whole sunshield 10 can be folded while being installed on the windshield 5 and unfolded once it is placed at the inner surface of the windshield 5. The first extension 20 defines a top edge of the sunshield 10 which may extend at least partially linear.

The first extension 20 may be neatly formed with the main body 11 or might be attached via a weakened or perforated portion along the respective upper border of the main body 11 so that the one or two first extensions 20 can be bent away, folded or flapped out to adapt to the respective size of the windshield.

It may further be provided that in addition to the first folding line F1 one or more additional second folding lines F1' may be provided within the one or two first extensions 20 substantially in parallel with the first folding line F1 so that the protrusion length of the first extension(s) 20 can be freely adapted to the specific type of windshield 5 by simply flapping the whole or a part of the respective one or two first extensions20 towards the interior 2 of the vehicle 1 in application state. In application state the one or two first extensions 20 may be folded onto the main body 11 and clamped to the inner surface of the windshield 5 by the sunvisor blades 71 flapped into the second position P2. The additional second folding lines FT may be parallel to the top edge defined by the first extension 20.

The first extension(s) 20 allow to securely attach the sunshieldIO onto the windshield5 using the fixedly installed sunvisor7 in the vehicle 1 without the need for any further attachment means.

Alternatively, as shown in Figure 12 fixation means 90 may be provided to fixate the sunshield at the sunvisor blades 71. The fixation means 90 may include a Velcro or magnetic attachment area 91 attached to the sunshield material and extending close and along the top edge of the sunshieldIO. Preferably, the attachment area 91 of the fixation means 90 extend in alignment with the top edge of the sunshield 10 and distanced therefrom with a distance of betweenl and 10 cm, preferably between 2 and 7 cm. This allows to attach the sunshield 10 to the sunvisor blade 71 kept in position P1.

The sunvisor blade 71 may be provided with a corresponding attachment area 92 of the fixation means which may be also a Velcro or magnetic band. The corresponding attachment area 92 of the fixation means 90 can be fixed on the sunvisor blade 71 or can be formed on a clip 93 so that the attachment areas 91 , 92 can be connected for mounting the sunshield. The corresponding attachment area 92 is outside when the sunvisor blade 71 is in position P1 in order to hold the attachment area 91 (Velcro/magnetic band) placed close to the top edge of the sunshield 10.

Further as shown in Figure 12c as fixation means a clip 93 may be used to couple the sunshield to the sunvisor blade 71. Also a combination of attachment area 91 and clip 93 holding the corresponding attachment area 92 may be provided.

A second extension 30 may be provided which connects to the lower border 13 and may have a convex curvature so that it has its maximum protrusion substantially at the vertical center line A which is formed by a symmetry line of the sunshield 10 and/or by a position of 50% of the width in a lateral direction L perpendicular to the height direction H. The second extension 30 defines a bottom edge of the sunshield 10 by its protruding edge wherein the bottom edge is substantially circularly or elliptically rounded. The second extension 30 may be attached to the main body11 or integrally formed therewith. A second folding line F2 may be applied between the second extension 30 and the main body 11 , preferably along the lower border 13 of the main body 11. The second extension 30 defines a bottom edge of the sunshield 10 which may substantially be circularly or elliptically or polynomial rounded

The second extension 30 may be neatly formed with the main body 11 or might be attached via a weakened or perforated portion along the respective lower borderl 3 of the main body 11 so that the second extension 30 can be bent away, folded or flapped out to adapt to the respective size of the windshield and the shape of the bottom edge of the windshield.

It may further be provided that in addition to the second folding line F2 one or more additional second folding lines F2' may be provided within the second extension 30 substantially in parallel with the second folding line F2 so that the protrusion length of the second extension 30 can be freely adapted to the specific type of windshield by simply flapping the whole or a part of the respective second extension towards the interior 2 of the vehicle 1 in application state. The additional second folding lines F2' may be parallel to the bottom edge defined by the second extension 30.

One or two third extensions 40 may be provided at one or two lateral borders 14, respectively, which protrude into the lateral direction L from the main body 11 which includes an outer corner defining a second height point H2. The outer corner may have a height over the lower border 13 which is even higher than the height point H1. Further the second height point H2 can be in the same height as the first height point H1 or even lower than the first height point H1. If the third extension(s) 40 have a shape which defines the second height point H2 to go beyond the height of the first height point H1 , the third extension 40 should have a shape with a top edge which prolongs the respective top edge of the respective first extension(s) 20 outwardly. This allows reaching even the lateral upper corners of the windshield 5 which would not be covered by the standard conventional sunshields. Furthermore, overall stability is maintained as no parts of the sunshield 10 protrude which are not sufficiently, i.e. along a sufficient width, attached with a respective border of the main body 11. The third extensions 40 may have a triangular shape which define straight right and left edges of the sunshield 10 and make the overall shape of the sunshield taper towards its bottom edge and which define the second height point H2 as a sharp angle.

Alternatively, the third extension(s) 40 may define a respective straight or partially linear or curved right and/or left side edge of the sunshield 10 and make the shape of the sunshield taper towards its bottom edge and/or towards its top edge.

Alternatively, also a partially linear or curved right and/or left edge of the sunshield 10 could be formed such that the lower part of the side edges of the sunshield located between 0% and at least 55%, particularly between 0% and at least 60% of the total height of the sunshield measured from the lowest level of the sunshield is widening in a vertical direction from the bottom edge to the top edge.

Particularly the one or two third extensions have an apex in the lateral direction at a height of at least 20cm, preferably of at least 22 cm, most preferably of at least 24cm from the lowest point of the bottom edge, wherein particularly at least one of the one or two third extensions have a triangular or polygon or concave or convex shape between the respective apex and the bottom edge and /or the top edge.

Particularly, the lower corner between the second and third extension is distanced in lateral/width direction from the nearest lateral apex at least by 5cm preferably 6cm at the height level of 10 cm measured from the lowest level of the bottom edge and/or at least by 3 cm, preferably 4cm at the height level of 15cm measured from the lowest level of the bottom and/or at least by 2cm, preferably 3cm at the height level of 18 cm measured from the lowest level of the bottom of the sunshield.

Alternatively, also a partially linear or curved right and/or left edge of the sunshield 10 could be formed such that the sunshield has a concave contour of the respective side edges in the lower part of the sunshield located between 0% and70%, particularly between 0% and 50%, preferably between 0% and 40% of the total height of the sunshield measured from the lowest level of the sunshield. Particularly, the concave contour is partly widening in direction of the top edge of the sunshield and/or partly parallel to the vertical center line. It usually does not widen in direction of the bottom edge.

The third extension(s) 40 may be attached to the main body 11 or integrally formed therewith. A third folding line F3 may be applied between the third extension 40 and the main body 11 , preferably along the lateral border 14. The third extension(s) 40 may be neatly formed with the main body 11 or might be attached via a weakened or perforated portion along the respective lateral border 13 of the main body 11 so that the third extension 40 can be bent away, folded or flapped out to adapt to the respective size of the windshield.

It may further be provided that in addition to the third folding line F3 one or more additional second folding lines F3' may be provided within the third extension 40 substantially in parallel with the third folding line F3 so that the protrusion length of the second extension 40 can be freely adapted to the specific type of windshield 5 by simply flapping the whole or a part of the respective third extension 40 towards the interior 2 of the vehicle 1 in installed state. The additional second folding lines F3' may be parallel to the side edge defined by the third extension 40.

Folding lines F1 , F2, F3, F1 ', F2', and F3' provide a preferred bending or hinging of the material of the sunshield 10 there along with respect to other areas of the sunshield 10.

It may be provided that the folding lines F1 ', F2', and F3' correspond to weakened or perforated or partially cut parts of material of the sunshield.

It becomes clear that each sole one of the first, second and third extensions 20, 30, 40 may even provide an improvement of coverage with respect to the standard conventional shaped sunshield. However, in combination of the extensions 20, 30, 40 provide a benefit which makes the sunshieldIO convenient to use. Furthermore, the first, second and third extensions 20, 30, 40 do not hinder the application of the sunshield on a minimum-sized windshield.

For example, in Figure5, a sunshieldI O, as which has been described in Figure 3, is attached to a windshield 5 with its full extension so that one can see the area which is additionally covered with respect to the standard conventional sunshields. Due to the first extensions 20, it might be possible, even with higher windshields, to clamp the sunshieldIO at its first extension 20 between the inner surface of the windshield 5 and the protruding edge of the fixedly installed sunvisors 7. The outer edges of the sunshield 10 having one or more of the first, second and third extensions 20, 30, 40 may be provided with collars which may be rounded and/or stiffened to facilitate handling.

Height adaption is performed by the first extension(s)20 and width adaption is substantially performed by the third extension(s) 40. The protrusion lengths of the first and third extensions 20, 40 from the upper border 12 of the main body 11 and the lateral borders 14 of the main body 1 1 may be between 1 to 20 cm, respectively, preferably between 2 to 15 cm, most preferably between 3 cm to 10cm to be applicable for any combinations of windshield sizes which have a width between the width of the main body 11 and the sum of the width of the main body 11 and two times the protrusion length of the third extension 40 and a height between the height of the main body 11 and the height plus the protrusion length of the first extension 20.

To provide a set of different sunshields 10 to cover a broad variety of differently sized windshields 5 of vehicles, the main body 11 of a second sunshield has a width determined by the dimensions of the main body 11 and of the third extensions 40 of a first sunshield 10 and a height determined by the dimensions of the main body 11 and the first and second extensions 20, 40 of the first sunshield. Therefore, it might be possible to cover all sizes of windshields by a number of 4 to 5 differently sized sunshield types as explained below.

Be E1 , E3 the widths of the first and third extensions 20, 40, respectively, and W and H the width and the height of the sunshield 10, then a set of sunshields can be formed with dimensions:

wherein H1 and W1 are the selected height and width of a sunshield adapted to the smallest windshield to be covered. As shown in Figure 6, transport folding lines F can be provided along the height direction to allow to bring the sunshieldIO into a proper transport state when not applied onto a windshield 5 of the vehicle 1 and for unfolding it to apply it into its installed state. At one or both ends of each transport folding line F, a notch 50 can be provided which can be arranged either at a top edge or at a bottom edge of the sunshieldIO and allows an easy handling and attaching the sunshieldIO to the windshield 5. The shape of these notches 50 can be essentially any shape, such as triangular, rectangular or circular and allows to provide a better/easy handling and a better support when placed between the dashboard and the windshield 5 or the windshield 5 and a folded-down sunvisor blade 71 , respectively. Notches insure that contacts between the ends of folding lines of the sunshield and the car dashboard occur without cumbersome sharp angles.

The notches 50 facilitate a partial unfolding of a sunshield 10 in place under a windshield which allows a wide sunshield to be installed under a small width windshield.

In the same sunshield, notches 50 may have different shapes and/or different sizes.

The notch 50 can be formed by a weakened area of sunshield material or can be defined by perforations or partial cuts so that sunshield material can be separated/removed before use of the sunshield to form the notch 50.

As shown in Figure 7, a sunshield 10 as described above can be provided in a unique size. Parallel to at least one of the top, side and/or bottom edges thin wires 9 or threads, such as thin plastic threads, forming a shape as described herein can be incorporated or glued on the sunshield material. By pulling off the wire 9 or thread the sunshield material is cut in/off so that a surplus area of the respective extension can be easily removed. The consumer will then use one or more of these wires 9 to get the specific size of the sunshield 10 that fits with the windshield of the vehicle 1 where the sunshield shall be applied on. Alternatively, weakened/perforated/partially cut lines forming a shape as described herein can be incorporated to the sunshield material so that sunshield material can be separated/removed by the consumer before use of the sunshield to produce a sunshield according to features described herein.

Figure 8 shows another embodiment wherein the sunshield has first, second and third extensions 20, 30, 40 and cut-ins 60 which are longitudinal cuts into the sunshield material at one or two corners between the bottom edge and a respective side edge. Furthermore, it is shown that corners and other irregular characteristics of the edges may be rounded as shown with reference sign 70. The cut-ins 60 can have any direction extending from the bottom edge or the side edges. Furthermore, the cut-ins 60 can have any shape such as a curvature extension or the like. Furthermore, the cut-ins can be formed by weakened and/or perforated and/or partially cut lines so that they can be separated/removed by the consumer before use of the sunshield.

As can be seen in Figure 9, cut-offs 80 may be provided which are removed corners with a substantially concave shape with respect to the body of the sunshield, wherein particularly the concave shape has a rounded or curved or polygon contour. Alternatively, the cut-offs 80 can be defined or made by weakened material so that they can be separated/removed by the consumer before use of the sunshield 10.

The cut-offs 80 may be arranged on one or both sides of the sunshield and may have any shape but ensure that the recess of the cut-offs 80 is at least of an area A which is defined on lower corners of both sides of the sunshield 10 as follows:

- The apex of the third extension 40 in the lateral direction is at least in a height of 20cm, preferably between 20cm and 45 cm, most preferably between 22cm and 24cm from the lowest level LL of the bottom edge of the sunshield 10.
