Description

Title of the invention: Packaging assembly for a pair of windshield wiper blades

[0001] The technical context of the present invention is that of the packaging of windshield wiper blades. More particularly, the invention relates to a packaging assembly for a pair of windshield wiper blades.

[0002] Wiping systems for motor vehicles are designed to remove, by sweeping, liquids and dirt present on a glass surface, such as for example a windshield for example, and likely to disturb a driver of such motor vehicles in his detection of a wheel scene or his environment.

[0003] Such known wiping systems generally comprise a drive arm which performs an angular back-and-forth movement, at the end of which is connected a windscreen wiper blade equipped with a scraper blade formed of an elastic material, or even rubber. In a known manner, the windscreen wiper blade comprises a connector for coupling said windscreen wiper blade to the drive arm. By rubbing against the glass surface, the scraper blades sweep away water and dirt, and evacuate them outside the driver's field of vision.

[0004] The friction of the scraper blade of the windshield wiper blades on the glass surface of the motor vehicle, the presence of dust or gravel on the glass surface during operation of the windshield wiper blade, or even the degradation of the wiping blade when not in use and its exposure to environmental factors such as sunlight and ozone, are factors which affect the quality of known windshield wiper blades and lead to wear of all or part of said windshield wiper blades.

[0005] Thus, such wiper blades form wear parts that need to be replaced more or less frequently, depending on their use. Since the wiper blades are located outside the vehicle and easily accessible, a user of the vehicle can replace them without any particular difficulty.

[0006] Windshield wiper blades are very commonly available for retail sale, not only at automotive-related outlets such as parts stores and gas stations, but also at general retail outlets such as discount stores and department stores.

[0007] For this purpose, we know the massive use of cardboard or plastic packaging forming a sheath in which a pair of windshield wiper blades is housed. Such known packaging has many disadvantages. Firstly, the use of plastic or cardboard to manufacture these disposable packagings is less and less compatible, or even no longer compatible, with the environmental standards of wiper blade manufacturers or retailers. In addition, the production of such cardboard or plastic packaging leads to a cost that should be minimized.

[0008] Another known disadvantage of the cardboard or plastic packaging used lies in the fact that, in these cardboard packagings, the wiper blades are not always perfectly held. Also, due to their construction and the desire, for example, for the scraper blade to naturally exert a pressure force on the glass surface, the wiper blades have a curved profile when they are housed in these packagings, thus leading to said packaging being oversized to allow easy insertion of the wiper blades. Of course, such a situation is not desired.

[0009] The object of the present invention is to provide a novel packaging assembly for a pair of windshield wiper blades in order to at least largely address the above problems and to further lead to other advantages.

[0010] Another object of the invention is to simplify the packaging of windshield wiper blades available on the aftermarket.

[0011] Another aim of the invention is to reduce the environmental impact of the packaging of windshield wiper blades sold as second-hand parts.

[0012] Another object of the invention is to reduce the cost of packaging windshield wiper blades sold as second-hand parts.

[0013] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a packaging assembly for a pair of windshield wiper blades, the packaging assembly comprising:

[0014] - a first wiper blade extending along a proper elongation axis and comprising a scraping blade held by at least one vertebra between two end caps, and a connector intended to allow mechanical coupling with a drive arm;

[0015] - a second wiper blade extending along the proper elongation axis and comprising a scraping blade held by at least one vertebra between two end caps, and a connector intended to allow mechanical coupling with a drive arm;

[0016] - a first integral sheath associated with the first wiper blade, the first sheath extending along the proper elongation axis and comprising a first bottom wall located at the level of the scraper blade of the first wiper blade and first lateral edges extending on either side of the first bottom wall

[0017] - a second integral sheath associated with the second wiper blade, the second sheath extending along the proper elongation axis and comprising a second bottom wall located at the level of the scraper blade of the first wiper blade and second side edges extending on either side of the second bottom wall;

[0018] - a tightening strap extending around the first sheath and the second sheath at the level of at least one of the connectors of the wiper blades, so as to keep the first sheath pressed against the second sheath.

[0019] In the packaging assembly according to the invention, at one axial end, the first bottom wall of the first sheath is connected to the second bottom wall of the second sheath by a tab.

[0020] In the context of the present invention, the elongation axis is taken along a direction of elongation of one of the wiper blades, along its largest dimension. For example, the elongation axis is parallel to a direction of elongation of the scraper blade of the wiper blade. From this elongation axis, a transverse direction is defined which extends perpendicular to the elongation axis, so as to delimit a front edge and a rear edge of the wiper blade. Finally, a vertical axis is also defined, taken simultaneously perpendicular to the elongation axis and the transverse axis. The vertical axis corresponds to a direction which extends from a wiping lip of the scraper blade to the at least one vertebra used to hold it.

[0021] In the context of the present invention, the packaging assembly thus forms an arrangement for storing and transporting a pair of wiper blades intended to be assembled together on a wiping system for a motor vehicle. Each wiper blade is intended to be coupled to a drive arm via its connector. As an illustrative example, the first wiper blade is intended to be mounted on a side opposite a direction of the motor vehicle, and the second wiper blade is intended to be mounted on the direction side of the motor vehicle. For this purpose, the first wiper blade is preferably shorter than the second wiper blade, taken along their respective elongation axis.

[0022] In the context of the present invention, but in a non-limiting manner, the first wiper blade and the second wiper blade are of the same type, only their dimensions taken along the axis of elongation may be different. In the packaging assembly according to the first aspect of the invention, the first wiper blade and the second wiper blade are aligned with respect to each other, so that their axis of elongation are made parallel to each other. Furthermore, in the packaging assembly according to the first aspect of the invention, the first wiper blade and the second wiper blade are off-center with respect to each other, so that the connector of the first wiper blade wiper blade is not located directly above the connector of the second wiper blade.

[0023] In the context of the present invention, the first lateral edges and the first bottom wall together delimit a housing for the first wiper blade, such that the first sheath is configured to at least partially house, relative to the vertical axis, the first wiper blade. Relative to the proper elongation axis, the first sheath has a length greater than or equal to that of the first wiper blade. The first lateral edges extend projecting from the first bottom wall of the first sheath.

[0024] In the context of the present invention, the second lateral edges and the second bottom wall together delimit a housing for the second wiper blade, such that the second sheath is configured to at least partially house, relative to the vertical axis, the second wiper blade. Relative to the proper elongation axis, the second sheath has a length greater than or equal to that of the second wiper blade. The second lateral edges extend projecting from the second bottom wall of the second sheath.

[0025] In the context of the present invention, and in a particularly advantageous manner, the first sheath and the second sheath are obtained by cutting a common die. The common die takes the form of a profile extending along the proper elongation axis and capable of being cut to predetermined dimensions, so as to create, by these cuts, the first sheath and the second sheath, said second sheath being connected to said first sheath by the tongue at an axial end of the first sheath and the second sheath. Thus, the first sheath and the second sheath have the transverse profile of the common die from which they originate. For this purpose, the die has cutting incipients which make it possible to form the first sheath and the second sheath and the tongue. Once thus cut, the die is folded back on itself at the tongue in order to form the first sheath and the second sheath.

[0026] The cutting primers comprise, for example, grooves and / or cutting lines and / or perforations. The cutting primers extend perpendicular to the proper elongation axis of the die. The cutting primers are formed to particular dimensions of the die, periodically, in order to be able to obtain die lengths - and therefore first sheath and second sheath lengths - predetermined as a function of the known lengths of wiper blades.

[0027] In the context of the present invention, the clamping strap is configured to keep the wiper blades connected to each other. The clamping strap thus forms a ring passing through all or part of the connector of at least one wiper blade, thereby preventing said wiper blades from separating from each other. when they are transported or handled. The tightening strap forms a closed contour around the two wiper blades, in a direction transverse to the axis of elongation of said wiper blades. The tightening strap is kept closed by any means, such as for example by gluing, by welding. The tightening strap is kept closed independently of one or the other of the wiper blades. Thus, in a clever manner, the tightening strap exerts on the wiper blades a compressive force which is taken up by the lateral edges and by the bottom wall of each sheath, thus making it possible to form a sufficiently rigid and stable assembly to allow the transport and packaging of the pair of wiper blades thus linked together. For this purpose, the first sheath and the second sheath are formed of a material sufficiently rigid to allow the pressure of the tightening strap in its context of use.Additionally, a thickness of the material forming the first sheath and the second sheath is sufficiently large to allow the pressure of the tightening strap in its context of use.

[0028] Thus, the packaging assembly according to the first aspect of the invention makes it possible to simplify the packaging of windshield wiper blades available on the aftermarket and to reduce the environmental impact of such packaging, by doing away with the sleeves used until now. Conversely, the windshield wiper blades are now only connected to each other and clamped in this state, protected by the first sleeve and the second sleeve. This configuration is particularly environmentally friendly since it makes it possible to reduce the quantity of materials used for packaging the windshield wiper blades. Consequently, it is also particularly economical since it makes it possible to reduce the cost of packaging such windshield wiper blades.

[0029] The packaging assembly in accordance with the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0030] - the tongue is made from the same material as the first sheath and the second sheath. By material, we understand that the tongue, the first sheath and the second sheath cannot be detached from each other without damaging their physical integrity, that is to say without damaging them in part or completely. The tongue, the first sheath and the second sheath are all produced by the same manufacturing process. As mentioned previously, they are all produced from a common matrix which has been cut in an ingenious manner in order to delimit the tongue between the first sheath and the second sheath and thus allow folding at the level of the tongue of the first sheath on the second sheath. Thus, the first sheath is mounted head to tail against the second sheath. In other words, the first sheath and the second sheath are placed against each other at the level of the first bottom wall and the second bottom wall respectively;

[0031] - the tab forms a flexible hinge between the first sheath and the second sheath. By flexible hinge, it is understood that the matrix from which the first sheath, the second sheath and the tab are derived has, at least at the level of said tab once cut, dimensions and / or a thickness which makes it possible to fold and rotate the matrix at the level of a folding axis which extends along the transverse axis of the packaging assembly according to the first aspect of the invention;

[0032] - the tab forms a fold. The fold thus formed extends along the transverse axis of the packaging assembly;

[0033] - the second bottom wall of the second sheath is supported against the first bottom wall of the first sheath. This advantageous configuration makes it possible to hold the first sheath and the second sheath together and against each other, when the tightening strap is affixed around said first sheath and said second sheath;

[0034] - the first sheath and the second sheath have the same transverse profile, taken perpendicular to the proper elongation axis. The transverse profile corresponds to a shape and dimensions of the first sheath and the second sheath, taken in the plane perpendicular to the proper elongation axis. For simplicity and optimization of manufacturing costs, it is advantageous for the first sheath and the second sheath to be of identical shape, since they come from the same matrix and because the wiper blades they house are often of the same type;

[0035] - according to a first embodiment, the first sheath and the second sheath have a transverse “U” profile. In this first embodiment, the first lateral edges and the second lateral edges extend in a secant manner - and preferably in a perpendicular or substantially perpendicular manner - to the first bottom wall and the second bottom wall respectively. By substantially perpendicular, it is understood that the lateral edges and the bottom wall of the corresponding sheath together form an angle of between 80° and 100°. The lateral edges make it possible at least to protect the scraper blade of the corresponding windscreen wiper blade, by framing it relative to the transverse axis;

[0036] - the first side edges and the second side edges have an edge free located at a base of the corresponding scraper blade. The free edge is located at a distance from the corresponding bottom wall. The free edge of the side edges is located opposite the scraper blade. In other words, the first side edges and the second side edges extend on either side of the scraper blade, such that the corresponding free edge is located close to the deflector of the corresponding wiper blade, relative to the vertical axis;

[0037] - more particularly, relative to the transverse axis, the first lateral edges and the second lateral edges are located in an intermediate position between a leading edge of the corresponding deflector and a side of the base of the corresponding scraper blade. In the context of the present invention, the leading edge of the deflector is the longitudinal extension edge, relative to the proper elongation axis of the corresponding wiper blade. The leading edge corresponds to a front edge or a rear edge of the wiper blade;

[0038] - according to a second embodiment, the first sheath and the second sheath have a stepped transverse profile, the first sheath and the second sheath respectively comprising first lateral flanks and second lateral flanks located on either side of a deflector of the first wiper blade and the second wiper blade respectively. In this embodiment, the first lateral flanks and the second lateral flanks delimit a housing for the deflector, in the extension of the housing delimited by the first lateral edges and the second lateral edges. Relative to the transverse axis, the first lateral flanks are further apart from each other than the first lateral edges, and the second lateral flanks are further apart from each other than the second lateral edges.The first lateral flanks and the second lateral flanks extend in a secant manner - and preferably in a perpendicular or substantially perpendicular manner - to the first bottom wall and the second bottom wall respectively. By substantially perpendicular, it is understood that the lateral flanks and the bottom wall of the corresponding sheath together form an angle of between 80° and 100°. The lateral flanks make it possible at least to protect the deflector of the corresponding wiper blade, by framing it relative to the transverse axis. The lateral flanks extend in the extension of the corresponding lateral edges; .

[0039] - the first lateral flanks extend parallel to the first lateral edges of the first sheath, and the second lateral flanks extend parallel to the second lateral edges of the second sheath;

[0040] - the first lateral flanks and the second lateral flanks have a free edge located at a top edge of the corresponding deflector. This advantageous configuration makes it possible to protect the deflector when the tightening strap is applied. By "at the level", it is understood that the free edge of the first lateral flanks and the second lateral flanks is located at the height or substantially below or substantially above the top edge of the deflector. The top edge is the line of the deflector which extends along the proper elongation axis and which is the furthest from the scraper blade relative to the vertical axis;

[0041] - in the first embodiment or the second embodiment, the first lateral edges and / or the second lateral edges and / or the first lateral flanks and / or the second lateral flanks are obtained by folding. In order to facilitate their shaping and folding, the matrix may comprise longitudinal grooves in order to materialize and facilitate the corresponding folding and the shaping of said lateral edges and / or said lateral flanks;

[0042] - according to a third embodiment, the first sheath and the second sheath have an elliptical transverse profile. Generally, the first sheath and the second sheath have a curved profile. More particularly, the first lateral flanges and the second lateral flanges extend in a curved manner from the first bottom wall and the second bottom wall, respectively. This advantageous configuration is simpler to manufacture and more economical;

[0043] - the first side edges and the second side edges have an edge free located at the connector of the first wiper blade and the second wiper blade respectively. This advantageous configuration makes it possible to better protect the wiper blades housed in the respective sheaths. Preferably, the first lateral edges and the second lateral edges have a free edge located beyond the connector of the first wiper blade and the second wiper blade respectively, relative to the corresponding scraper blade;

[0044] - the first sheath and the second sheath are advantageously formed of any biodegradable material, preferably cardboard or seaweed fibers;

[0045] - according to a first variant embodiment, a width of the tightening strap, taken relative to an axis of elongation of the wiper blades, is greater than half of a length of the connector of one of the wiper blades, taken relative to the axis of elongation of said wiper blades. This advantageous configuration makes it possible to optimize the holding of the two wiper blades together, and also facilitates the placement and stability of the tightening strap on the connectors;

[0046] - alternatively, according to a second variant embodiment, a width of the tightening strap, taken relative to an axis of elongation of the wiper blades, is less than half a length of the connector of one of the wiper blades, taken relative to the axis of elongation of said wiper blades. This advantageous configuration is more economical in material constituting the tightening strap;

[0047] - in the first embodiment, the tightening strap is of the ribbon type. By ribbon, we understand that a width of the tightening strap, taken relative to the axis of elongation when mounted on the pair of wiper blades, is greater than thirty times a thickness of said tightening strap;

[0048] - in the second embodiment, the tightening strap is preferably of the type of a rope or cord. By rope or cord, it is understood that a width of the tightening strap, taken relative to the axis of elongation when mounted on the pair of wiper blades, is less than twenty times a thickness of said tightening strap. Optionally, the tightening strap is formed of an elastic material, such as rubber or an elastomer;

[0049] - in either of the embodiments, the tightening strap is formed of a plastic or paper material, possibly made of fibers and / or braided.

[0050] Various embodiments of the invention are provided, integrating according to all of their possible combinations the different optional characteristics set out here.

[0051] Other characteristics and advantages of the invention will become apparent from the following description on the one hand, and from several exemplary embodiments given for informational and non-limiting purposes with reference to the appended schematic drawings on the other hand, in which:

[0058] Of course, the features, variants and different embodiments of the invention may be combined with each other, in various combinations, provided that they are not incompatible or mutually exclusive. In particular, variants of the invention may be imagined comprising only a selection of features described below in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the prior art.

[0059] In particular, all the variants and all the embodiments described can be combined with each other if nothing prevents this combination from a technical point of view.

[0060] In the figures, the elements common to several figures retain the same reference.

[0061] In the FIGURES described below, the elongation axis is defined along a direction of elongation of one of the wiper blades 10A, 10B, taken along its largest dimension. For example, the elongation axis is parallel to a direction of elongation of a scraper blade 101 of one of the wiper blades 10A, 10B. From this elongation axis, a transverse direction is also defined which extends perpendicular to the elongation axis, so as to delimit a front edge and a rear edge of the wiper blades 10A, 10B. Finally, a vertical axis is defined, taken simultaneously perpendicular to the elongation axis and to the transverse axis. The vertical axis corresponds to a direction which extends from a wiping lip of the scraper blade 101 to the at least one vertebra used to hold it.

[0062] With reference to FIGURES 1 to 6, the invention relates to a packaging assembly 1 for a pair of windshield wiper blades 10A, 10B, the packaging assembly 1 comprising:

[0063] - a first wiper blade 10A extending along an elongation axis clean 01 and comprising a scraping blade 101 held by at least one vertebra between two end caps, and a connector 104 intended to allow mechanical coupling with a drive arm;

[0064] - a second wiper blade 10B extending along the elongation axis clean 01 and comprising a scraping blade 101 held by at least one vertebra between two end caps, and a connector 104 intended to allow mechanical coupling with a drive arm;

[0065] - a first sheath 1 IA integrally associated with the first windshield wiper blade 10A, the first sheath 1 IA extending along the proper elongation axis 01 and comprising a first bottom wall 11 IA located at the level of the scraper blade 101 of the first windshield wiper blade 10A and first lateral edges 112A extending on either side of the first bottom wall 11 IA;

[0066] - a second sheath 1 IB integral with the second windshield wiper blade 10B, the second sheath 11B extending along the proper elongation axis 01 and comprising a second bottom wall 11 IB located at the level of the scraper blade 101 of the first windscreen wiper blade 10A and second lateral edges 112B extending on either side of the second bottom wall 11 IB;

[0067] - a tightening strap 13 extending around the first sheath 1 IA and the second sheath 11B at the level of at least one of the connectors 104 of the wiper blades 10A, 10B, so as to keep the first sheath 11A pressed against the second sheath 11B.

[0068] In the packaging assembly 1 according to the invention, at an axial end of said packaging assembly 1, taken relative to the axis of elongation own 01, the first bottom wall 11 IA of the first sheath 1 IA is connected to the second bottom wall 11 IB of the second sheath 1 IB by a tab 12.

[0069] As visible in the FIGURES, the first wiper blade 10A and the second wiper blade 10B are aligned with each other at one of their end caps, relative to the proper elongation axis 01. Thus, the connector 104 of the first wiper blade 10A is offset relative to the connector 104 of the second wiper blade 10B, relative to the proper elongation axis 01, so that said connectors 104 are then not located opposite each other in the packaging assembly 1 according to the invention.

[0070] In the embodiments illustrated in FIGURES 1 to 6, the wiper blades 10A, 10B are not of the same length, taken relative to the proper elongation axis 01. However, the invention is not limited to this configuration and the wiper blades 10A, 10B could be of the same length. On the other hand, in all cases, it is preferable that the end cap of the first wiper blade 10A and the end cap of the second wiper blade 10B are located together near the tab 12.

[0071] In the embodiments illustrated in FIGURES 1 to 6, the packaging assembly 1 comprises a single tightening strap 13. The tightening strap 13 passes around the connector 104 of the first wiper blade 10A and around the deflector 103 and the scraper blade 101 of the second wiper blade 10B, in order to hold said wiper blades 10A, 10B together. The tightening strap 13 forms a ring passing around the wiper blades 10A, 10B. The tightening strap 13 thus forms a closed contour around the two wiper blades 10A, 10B. The tightening strap 13 is kept closed around the wiper blades 10A, 10B by any means, such as for example by gluing, by welding. In the embodiments illustrated in the FIGURES, the tightening strap 13 takes the form of a ribbon, two longitudinal ends of which are attached to one another and fixed securely to one another, for example by gluing.

[0072] In the embodiments illustrated in FIGURES 1 to 6, a width of the tightening strap 13, taken relative to the proper elongation axis 01 of the wiper blades 10A, 10B, is greater than half of a length of the connector 104 of one of the wiper blades 10A, 10B, taken relative to the proper elongation axis 01 of said wiper blades 10A, 10B. By way of non-limiting example, a width of the tightening strap 13 is between 5 cm and 10 cm.

[0073] In order to improve the holding and clamping of the first wiper blade 10A against the second wiper blade 10B, the tightening strap 13 is advantageously formed from a heat-sensitive material which contracts irreversibly under the effect of the application of a heat flow greater than a threshold temperature. such tightening strap 13 is then thermoformable and can, once placed around the wiper blades 10A, 10B, be heated in order to be retracted and to circumferentially overmold the arrangement of the two wiper blades 10A, 10B placed against each other.

[0074] In a particularly interesting manner in the context of the present invention, the tightening strap 13 is preferably formed from a bio-sourced material, such as comprising for example plant fibers, algae, paper or cardboard, etc.

[0075] The first wiper blade 10A and the second wiper blade 10B are placed opposite each other, in an inverted manner, so that the scraper blade 101 of the first wiper blade 10A is oriented, relative to the vertical axis, in the direction of the second wiper blade 10B, and the scraper blade 101 of the second wiper blade 10B is oriented, relative to the vertical axis, in the direction of the first wiper blade 10A.

[0076] Relative to the transverse axis, the first wiper blade 10A is aligned with the second wiper blade 10B, so that the scraper blade 101 of the first wiper blade 10A is located directly above the scraper blade 101 of the second wiper blade 10B.

[0077] The two wiper blades 10A, 10B extend parallel to each other, relative to the proper elongation axis 01.

[0078] Each wiper blade 10A, 10B is housed in a particular sheath 11A, 11B, the two sheaths 11A, 11B being made of material and obtained from the same common matrix by cutting and folding in order to fold the second sheath 11B against the first sheath 11A, via a fold formed by the tab 12, so that the second bottom wall 111B of the second sheath 11B is placed in opposition, and preferably in abutment, against the first bottom wall 111A of the first wiper blade 10A. The tab 12 thus forms a flexible hinge between the first sheath 11A and the second sheath 11B.

[0079] In the embodiment illustrated in FIGURES 1 to 3, the first sheath 11A and the second sheath 11B have a transverse profile whose general shape is “U”. More particularly, the first sheath 11A and the second sheath 11B have a stepped transverse profile.

[0080] In this embodiment, the first sheath 11A comprises first lateral edges 112A which extend perpendicularly to the first bottom wall 111A; and the second sheath 11B comprises second lateral edges 112B which extend perpendicularly to the second bottom wall 111B. Relative to the transverse axis, the first lateral edges 112A and the second lateral edges 112B are located in an intermediate position between a leading edge 114 of the deflector 103 of the corresponding windshield wiper blade 10A, 10B and a lateral side 115 of the base 102 of the scraper blade 101 of said corresponding wiper blade 10A, 10B.

[0081] Relative to the vertical axis, the first lateral edges 112A and the second lateral edges 112B extend from the first bottom wall 11 1A and the second bottom wall 11 1B respectively, in the direction of the scraper blade 101 and up to the vicinity of a base 102 of said corresponding scraper blade 101. In particular, the first lateral edges 112A and the second lateral edges 112B extend up to a lower face of one of the vertebrae of the corresponding wiper blade 10A, 10B.

[0082] Additionally, the first sheath 11A comprises first lateral flanks 113A located on either side of the deflector 103 of the first wiper blade 10A; and the second sheath 11B comprises second lateral flanks 113B located on either side of the deflector 103 of the second wiper blade 10B, so that the first lateral flanks 113A and the second lateral flanks 113B delimit a housing for the deflector 103 of the corresponding wiper blade 10A, 10B.

[0083] The first lateral flanks 113A and the second lateral flanks 113B are respectively connected to the first lateral edges 112A and to the second lateral edges 112B by lateral sidewalls 116 which extend outwards, relative to the wiper blade 10A, 10B. The lateral sidewalls 116 preferably extend parallel or substantially parallel to the corresponding bottom wall 111A, 111B. The lateral sidewalls 116 extend below and opposite one of the vertebrae of the corresponding wiper blade 10A, 10B, and / or below and opposite the deflector 103 of the corresponding wiper blade 10A, 10B.

[0084] The first lateral flanks 113A extend from the first lateral flanges, and the second lateral flanks 113B extend from the second lateral flanges. More particularly, the first lateral flanks 113A and the second lateral flanks 113B extend from a free end of the lateral sidewalks 116, relative to the first lateral flanges 112A and the second lateral flanges 112B respectively. Relative to the transverse axis, the first lateral flanks 113A are further apart from each other than the first lateral flanges 112A, and the second lateral flanks 113B are further apart from each other than the second lateral flanges 112B.

[0085] The first lateral flanks 113A extend perpendicularly to the first bottom wall 111A of the first sheath 11A; and the second lateral flanks 113B extend perpendicularly to the second bottom wall 111B of the second sheath 11B.

[0086] Relative to the vertical axis, the first lateral flanks 113A and the second lateral flanks 113B are located at the height of the deflector 103 of the corresponding wiper blade 10A, 10B. The lateral flanks 113A, 113B thus make it possible to protect the deflector 103 of the corresponding wiper blade, by framing it relative to the transverse axis.

[0087] Thus, in this tiered embodiment, the first sheath 11A and the second sheath 11B respectively delimit:

[0088] - a first housing for the corresponding scraper blade 101, delimited by the first side edges 112A and second side edges 112B;

[0089] - a second housing for the corresponding deflector 103, delimited by the first lateral flanks 113A and the second lateral flanks 113B.

[0090] In this first embodiment illustrated in FIGURES 1 to 3, the first lateral flanks 113A and the second lateral flanks 113B have a free edge 110 located at the level of a top edge of the corresponding deflector 103. Consequently, as visible in [Fig.2], the tightening strap 13 is then in abutment against the free edges 110 corresponding to the level of the second sheath 11B.

[0091] In the embodiment illustrated in FIGURES 4 to 6, the first sheath 11A and the second sheath 11B have an elliptical transverse profile. More particularly, the first lateral edges 112A and the second lateral edges 112B of the first sheath 11A and the second sheath 11B extend in a curved manner from the first bottom wall 111A and the second bottom wall 111B respectively, so that the first sheath 11A and the second sheath 11B have a curved profile.

[0092] In this embodiment, the first sheath 11A comprises first lateral edges 112A which extend in a curved manner from the first bottom wall 111A and towards the deflector 103 of the first wiper blade 10A; and the second sheath 11B comprises second lateral edges 112B which extend in a curved manner from the second bottom wall 111B and towards the deflector 103 of the second wiper blade 10B. Relative to the transverse axis, the first lateral edges 112A and the second lateral edges 112B are located on either side of the corresponding wiper blade 10A, 10B.

[0093] Relative to the vertical axis, the first lateral edges 112A and the second lateral edges 112B extend from the first bottom wall 11 1A and the second bottom wall 11 1B respectively, in the direction of the scraper blade 101 and up to the vicinity of the corresponding deflector 103. In particular, as visible in FIGURES 2 and 3, the free edge 110 of the first lateral edges 112A and the second lateral edges 112B is located at least at the level of the corresponding deflector 103, and advantageously at the level - or even beyond - of the corresponding connector 104, so as to protect the entire corresponding wiper blade 10A, 10B.

[0094] Thus, in this elliptical embodiment, the first sheath 11A and the second sheath 11B respectively delimit a housing for the entire corresponding windscreen wiper blade 10A, 10B, including its connector 104.

[0095] In summary, the invention relates to a packaging assembly 1 for a pair of windshield wiper blades 10A, 10B, the packaging assembly 1 comprising a first windshield wiper blade 10A extending along a specific elongation axis 01 and housed in a first sheath 11A, a second windshield wiper blade 10B extending along the specific elongation axis 01 and housed in a second sheath 11B, a tightening strap 13 extending around the first sheath 11A and the second sheath 11B at at least one of the connectors 104 of the windshield wiper blades 10A, 10B, so as to keep the first sheath 11A pressed against the second sheath 11B, the first sheath 11A being connected to the second sheath 1 IB by means of a tab 12 connecting a first bottom wall 11 IA of said first sheath 11A to a second bottom wall 11 IB of said second sheath 1 IB,so that the first sheath 1 IA and the second sheath 1 IB are made of material. ,

[0096] Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, forms, variants and embodiments of the invention can be associated with each other in various combinations insofar as they are not incompatible or exclusive of each other. In particular, all the variants and embodiments described above can be combined with each other.
