[0002] The invention relates to a wiper blade device with a wind deflector unit, which has at least one wind deflector element.

[0003] It is proposed that the wind deflector unit include at least one fastening element designed for attaching a washer fluid unit and formed integrally with the wind deflector element. The term "wiper blade assembly" is understood to mean, in particular, at least one part, especially a subassembly, of a wiper blade, and may also include accessory units for the wiper blade, such as at least one wiper blade adapter and / or at least one end cap and / or at least one spray unit and / or at least one washer fluid channel element. In particular, the wiper blade assembly may also include the entire wiper blade.In this context, a "wind deflector unit" is understood to mean, in particular, a unit designed to deflect airflow or wind acting on the wind deflector unit and / or a wiper blade, and / or to press a wiper blade against a surface to be wiped, especially a windshield to be cleaned. Preferably, the wind deflector unit consists at least partially of rubber and / or of a partially elastic plastic. Preferably, the wind deflector unit has at least one concave front surface. The wind deflector unit differs, in particular, from an end cap unit, a wiper lip, and / or a wiper blade adapter. Advantageously, in an operating state, the wind deflector unit extends at least a large part, and in particular the entire, longitudinal extent of a wiper blade.Preferably, the wind deflector unit has at least one retaining element for attachment to a spring rail and / or a wiper strip. In this context, "airflow" is understood to mean, in particular, a flow that strikes the wind deflector unit at a specific airflow velocity. "Airflow velocity" is understood to mean, in particular, the velocity of an airflow relative to at least one point on the wind deflector unit. The wind deflector element is, in particular, a basic body of the wind deflector unit. Specifically, the wind deflector element defines a geometric shape of the wind deflector unit, at least partially and advantageously at least to a large extent. The wind deflector element, in particular, provides a primary function of wind deflection.In particular, the fastening element is an element designed to secure the washer fluid unit in at least one assembled state. The fastening element is specifically designed to secure at least a part of the washer fluid unit, and in particular at least a part of at least one component of the washer fluid unit, in at least one assembled state. A "washer fluid unit" is understood to be, in particular, a unit designed to receive washer fluid in at least one operating state and / or to transport washer fluid, especially along a longitudinal direction of the unit, and / or to dispense washer fluid. In this context, "washer fluid" is understood to be, in particular, a liquid suitable for washing and / or cleaning a vehicle windshield, such as, in particular, water, alcohols, or mixtures containing water, antifreeze, and / or alcohol.The washer fluid unit is advantageously designed to at least assist in the cleaning of a windshield, particularly a vehicle windshield. "One-piece" is understood to mean, in particular, at least materially bonded, for example, by a welding process, an adhesive process, an injection molding process, and / or another process that would appear appropriate to a person skilled in the art, and / or advantageously formed in one piece, such as by being manufactured from a single casting and / or by being manufactured using a single- or multi-component injection molding process, and advantageously from a single blank. "Provided for" is understood to mean, in particular, specially designed and / or equipped.The fact that an object is intended for a specific function should be understood in particular to mean that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0004] The inventive fastening of the wash water unit to the fastening element of the wind deflector unit allows for particularly easy fastening and / or good accessibility of the wash water unit. The inventive design, in the form of a single-piece assembly of the fastening element and wind deflector element, allows for particularly high stability. In particular, the risk of the wash water unit being lost during operation is prevented. In particular, different wash water units can be attached to the fastening element, thus enabling a particularly flexible design.

[0005] Furthermore, it is proposed that the fastening element extend over at least a substantial portion of the longitudinal extent of the wind deflector element. The term "longitudinal extent" of an object is understood to mean, in particular, the object's extent in a longitudinal direction. The term "extent" of an object is also understood to mean, in particular, the maximum distance between two points of a perpendicular projection of the object onto a plane. The term "longitudinal extent direction" of an object is also understood to mean, in particular, a direction that is parallel to the longest side of the smallest imaginary geometric cuboid that just completely encloses the object.In particular, the fastening element extends over a proportion of at least 20%, more particularly at least 40%, advantageously at least 60%, particularly advantageously at least 80%, preferably at least 90%, and most preferably at least 95% of the longitudinal extent of the wind deflector element. This allows for a high degree of flexibility regarding the mounting position of the wash water unit on the wind deflector unit. The wash water unit can be connected to the wind deflector unit at any point on the wind deflector unit.

[0006] Furthermore, it is proposed that the fastening element be arranged laterally on the wind deflector unit with respect to a wiping direction and / or a transverse direction of the wind deflector unit. In particular, when viewed as a projection onto a plane, which is at least substantially parallel to the pane to be cleaned, the fastening element forms an edge boundary of the wind deflector unit. A "transverse direction" of an object is understood to mean, in particular, a direction perpendicular to a longitudinal direction of the object. The transverse direction of the wind deflector unit is, in particular, parallel to the pane to be cleaned. This ensures, in particular, good application of cleaning water to the pane.Wash water can be applied to the windshield to be cleaned, particularly in one wiping direction, in front of a wiper blade that incorporates the wiper blade assembly. This allows for easy access to the mounting element and / or simple installation of the washer fluid unit.

[0007] For example, the fastening element could have at least one contact surface designed for a material-bonded connection with the wash water unit. Advantageously, the fastening element is designed to secure the wash water unit by friction and / or positive locking. Preferably, the fastening element is designed as a snap-fit ​​element that engages with the wash water unit. This allows for quick and / or easy mounting of the wash water unit to the fastening element and / or quick and / or easy removal of the wash water unit from the fastening element.

[0008] For example, the fastening element could be designed to engage at least partially with a corresponding locking element and / or to engage behind a corresponding locking element in at least one assembled state. Advantageously, the fastening element provides at least one locking receptacle. Preferably, the fastening element forms at least one locking receptacle which is designed to receive at least one part of the wash water unit, in particular at least one part of at least one object of the wash water unit. Advantageously, the fastening element is designed to receive and / or engage at least partially with a corresponding locking element in at least one assembled state.The corresponding locking element is, in particular, at least an outer shape and / or at least an outer form of the part of the wash water unit, especially of the part of the wash water unit object, which receives the fastening element in the assembled state. In at least one assembled state, the wash water unit is, in particular, clipped onto the fastening element. When viewed in a cross-sectional plane, which is, in particular, oriented perpendicular to a longitudinal direction of the fastening element, the fastening element has, in particular, a shape that is at least substantially oval-shaped and, in particular, open on one side.For example, when viewed in a cross-sectional plane, particularly one perpendicular to a longitudinal direction of the fastener, the fastener could have a shape that is at least substantially clamp-shaped and / or groove-shaped. When viewed in a cross-sectional plane, particularly one perpendicular to a longitudinal direction of the fastener, the fastener could have a shape that is at least substantially C-shaped. Along a longitudinal direction of the fastener, the fastener has a cross-sectional shape that is at least substantially unchanged. A cross-sectional shape of an object is, in particular, the shape of the object when viewed in a cross-sectional plane, particularly one perpendicular to a longitudinal direction of the object.This allows for a secure mounting of the wash water unit. Specifically, it enables easy installation of the wash water unit on the mounting element and / or easy removal of the wash water unit from the mounting element.

[0009] Furthermore, it is proposed that the fastening element be designed to selectively fasten and, in particular, at least partially accommodate at least one spray unit of the wash water unit, or at least one wash water channel element of the wash water unit, or both the spray unit and the wash water channel element. In particular, the wash water unit comprises at least the spray unit, which can be attached to the fastening element in at least one mounted state. The spray unit comprises, in particular, at least one fastening element corresponding to the fastening element. Advantageously, the corresponding fastening element is a corresponding locking element. A "spray unit" is understood to mean, in particular, a unit designed to convey, in at least one spray direction, at least one liquid onto at least one disc to be cleaned in at least one operating state, in particular to spray it.The spray unit has, in particular, at least one nozzle element which, in at least one operating state, is designed to spray at least one liquid onto the windshield to be cleaned. The spray unit also has, in particular, at least one channel element which is designed to connect, in particular, at least the washer fluid channel element and, in particular, to receive washer fluid. The liquid could, in particular, be water and / or washer fluid and / or cleaning fluid. The spray direction is, in particular, oriented at least substantially perpendicular to a surface of the spray unit, in particular to a surface of the nozzle element of the spray unit. The spray direction is, in particular, directed away from the spray unit, and especially from the nozzle element of the spray unit. For example, the spray direction could be oriented radially to a wiper path.Advantageously, the spray direction is aligned at least substantially parallel to a wiping direction. In particular, the wiper blade, which includes the wiper blade assembly, sweeps across the wiping path in the operating state. The washer water unit, in particular, includes at least the washer water channel element, which can be attached to the mounting element, especially in at least one mounted state. The washer water channel element, in particular, includes at least one mounting element corresponding to the mounting element. Advantageously, the corresponding mounting element is a corresponding locking element. The mounting element is designed, in particular, to encompass and / or receive at least a large portion of the corresponding mounting element, especially the spray unit and / or the washer water channel element, in the mounted state.The internal shape of the fastening element and the external shape of the corresponding fastening element, in particular the spray unit and / or the wash water channel element, are designed to correspond to each other. In this context, a "wash water channel element" is understood to be a tubular element designed to convey wash water. Preferably, the wash water channel element is a wash water hose and is advantageously flexible and / or elastic. Alternatively, the wash water channel element could be at least substantially rigid. This prevents, in particular, the loss of at least one component of the wash water unit during operation. In particular, the spray unit can be arranged in close proximity to the window being cleaned.In particular, a protected arrangement of the wash water channel element can be enabled and / or damage to a wash water channel element that is at least largely freestanding can be prevented.

[0010] Furthermore, it is proposed that the wind deflector unit be extruded, particularly co-extruded. For example, the wind deflector element and the mounting element could be manufactured in one piece, especially using a single-component extrusion process. Alternatively, the wind deflector element and the mounting element could be manufactured using a multi-component extrusion process. This would allow for particularly high stability.

[0011] For example, the wind deflector element could be designed at least substantially asymmetrically and, in particular, have a shape that is at least substantially asymmetrical. Advantageously, the wind deflector element is designed at least substantially mirror-symmetrically and, in particular, has a shape that is at least substantially mirror-symmetrical. In particular, the wind deflector element has at least one plane of symmetry, which is oriented, in particular, at least substantially perpendicular to the pane to be cleaned. This allows, in particular, for the simple manufacture of the wind deflector element.

[0012] A particularly well-cleaned windscreen can be achieved by a washer water unit for a wiper blade device according to the invention.

[0013] High stability and / or good attachment of the wash water unit can be achieved by a wind deflector unit for a wiper blade device according to the invention.

[0014] A wiper blade with a wiper blade device according to the invention makes it possible to achieve optimal cleaning of a window to be cleaned.

[0015] Particularly high stability can be achieved by a method for manufacturing a wiper blade device according to the invention, comprising a wind deflector unit which has at least one wind deflector element and at least one fastening element provided for fastening a washer water unit, wherein the wind deflector element and the fastening element are integrally joined. In particular, the wind deflector unit is extruded and / or co-extruded. For example, the wind deflector element and the fastening element could be made of the same material. Alternatively, the wind deflector element and the fastening element could be made of different and / or distinct materials. In particular, high stability can be achieved.

[0016] The wiper blade device according to the invention is not intended to be limited to the application and embodiment described above. In particular, the wiper blade device according to the invention may, in order to fulfill a function described herein, have a different number of individual elements, components and units than the number mentioned herein. drawing

Description of the exemplary implementations

[0019] Fig. Figure 1 shows a section of a wiper blade 24a with a wiper blade assembly 10a. The wiper blade assembly 10a has a wiper strip 26a (see Figure 1). Fig. 1 and 3 to 5). The wiper strip 26a is largely made of an elastic material. The wiper strip 26a is designed to be moved in contact with the window to be cleaned.

[0020] The wiper blade device 10a has at least one spring rail 28a (see Fig. 1 and 3 to 5). In the present embodiment, the wiper blade device 10a has two spring rails 28a. Only one of the spring rails 28a is described below. Of objects present multiple times, only one is indicated with a reference numeral in each figure.

[0021] The spring rail 28a has an extension that, under normal operating conditions, can be elastically varied by at least 10%, in particular by at least 20%, preferably by at least 30%, and most advantageously by at least 50%. The spring rail 28a generates a counterforce that is dependent on and proportional to the change in extension and that opposes the change.

[0022] The wiper blade device 10a includes a wind deflector unit 12a (see Fig. 1 to 5). The wind deflector unit 12a is designed for and specifically formed for the wiper blade assembly 10a. For example, the wind deflector unit could be co-extruded. In the present embodiment, the wind deflector unit 12a is extruded.

[0023] The wind deflector unit 12a has a wind deflector element 14a (see Fig. 1 to 5). The wind deflector element 14a forms a basic body of the wind deflector unit 12a. In an operating state, the wind deflector element 14a performs a main function of the wind deflector unit 12a. The wind deflector element 14a has a substantially aerodynamic shape. In the operating state, the wind deflector element 14a directs an effective airflow by means of its substantially aerodynamic shape. In the operating state, the wind deflector element 14a utilizes this effective airflow, via its substantially aerodynamic shape, to press against the disc to be cleaned.

[0024] The wind deflector unit 12a has a fastening element 16a (see Fig. 1 to 5). The fastening element 16a is formed integrally with the wind deflector element 14a. The fastening element 16a extends over a substantial part of a longitudinal extent of the wind deflector element 14a (see Figure 1). Fig. 2) For example, the fastening element could extend over substantially 20% of the longitudinal extent of the wind deflector element. In the present embodiment, the fastening element 16a extends over substantially the entire longitudinal extent of the wind deflector element 14a.

[0025] With respect to a wiping direction (not shown), the fastening element 16a is arranged laterally on the wind deflector element 14a. The fastening element 16a is located on a side of the wind deflector element 14a that faces in the wiping direction. In the operating state, the fastening element 16a forms a lateral boundary of the wind deflector unit 12a when viewed in the wiping direction.

[0026] The wiping direction is the direction in which the wiper blade 24a, in its operating state, moves across the windshield to be cleaned, starting from its rest position. A direction in which the wiper blade 24a, in its operating state, moves across the windshield to be cleaned, starting from a reversed position and returning to its rest position, is opposite to the wiping direction. The rest position of the wiper blade 24a is the position in which the wiper blade 24a is arranged, particularly in the operating state of a motor vehicle equipped with the wiper blade 24a, for a significant portion of the time under dry weather conditions.

[0027] The wiper blade assembly 10a is manufactured in a process for manufacturing the wiper blade assembly 10a. In the process, the wind deflector unit 12a is manufactured. The wind deflector unit 12a is extruded. The wind deflector element 14a and the fastening element 16a are joined together in one piece.

[0028] The wiper blade device 10a has a wash water unit 18a (see Fig. 1 and 3 to 5). The wash water unit 18a is designed for the wiper blade assembly 10a and is specifically designed for the wiper blade assembly 10a. In the present embodiment, the wash water unit 18a has several spray units 20a. Only one of the spray units 20a will be described below.

[0029] The wash water unit 18a has several wash water channel elements 22a. Only one of the wash water channel elements 22a will be described below. The wash water channel element 22a is designed as a wash water hose.

[0030] The spray unit 20a has at least one nozzle element 30a (see Fig. 1 and 3 to 5). In the present embodiment, the spray unit 20a has two nozzle elements 30a. Only one of the nozzle elements 30a will be described below. The nozzle element 30a is arranged in a region of the spray unit 20a facing the disc to be cleaned when the unit is mounted. With respect to the wiping direction, the nozzle element 30a is arranged laterally on the spray unit 20a.

[0031] The spray unit 20a has at least one channel element 32a (see Fig. 1 and Fig. 3) In the present embodiment, the spray unit 20a has two channel elements 32a. The channel elements 32a are arranged on opposite sides of the spray unit 20a with respect to a longitudinal direction of the spray unit 20a. Only one of the channel elements 32a will be described below.

[0032] Channel element 32a is designed to connect to the wash water channel element 22a. In the operating state, the wash water channel element 22a encompasses part of channel element 32a of the spray unit 20a. In the operating state, the wash water channel element 22a is positively locked to channel element 32a.

[0033] The channel element 32a has a first channel section 34a. The first channel section 34a is located in a region of the spray unit 20a facing away from the nozzle element 30a. The first channel section 34a has a substantially frustoconical shape.

[0034] The channel element 32a has a second channel section 36a. The second channel section 36a is arranged between the nozzle element 30a and the first channel section 34a. The second channel section 36a has a substantially cylindrical shape. A cross-sectional area of ​​the second channel section 36a and a cross-sectional area of ​​the first channel section 34a facing away from the second channel section 36a are substantially identical.

[0035] In this operating state, the wash water channel element 22a essentially and advantageously completely surrounds the first channel section 34a. In this operating state, the wash water channel element 22a partially surrounds the second channel section 36a.

[0036] In the present embodiment, the nozzle element 30a is designed to spray wash water in a spray direction 38a onto the disc to be cleaned (see figure). Fig. 5) The spray direction 38a is aligned in the wiping direction. The nozzle element 30a is designed to spray wash water onto the windshield to be cleaned in a spray direction 38a that is essentially parallel to the windshield being cleaned.

[0037] In its operating state, the wash water unit 18a is largely attached to the wind deflector unit 12a. The fastening element 16a is designed to secure the wash water unit 18a. When installed, the fastening element 16a secures the wash water unit 18a. The fastening element 16a is designed as a snap-fit ​​element, which is intended to engage with the wash water unit 18a.

[0038] In its assembled state, the fastening element 16a receives part of the wash water unit 18a. The fastening element 16a forms a snap-in recess designed to receive this part of the wash water unit 18a. In its assembled state, the fastening element 16a receives part of the spray unit 20a and / or part of the wash water channel element 22a.

[0039] The fastening element 16a is designed to selectively fasten either the spray unit 20a of the wash water unit 18a, or the wash water channel element 22a of the wash water unit 18a, or the spray unit 20a and the wash water channel element 22a. In the present embodiment, the fastening element 16a fastens the spray unit 20a and the wash water channel element 22a in the assembled state.

[0040] Before mounting the wash water unit 18a on the mounting element 16a, the wash water unit 18a is first mounted (see figure). Fig. 3) Alternatively, individual objects of the wash water unit could first be attached to the fastening element and then connected to each other, for example by moving, in particular displacing, at least one object of the wash water unit in the snap-in recess formed by the fastening element along a longitudinal direction of the fastening element.

[0041] The spray unit 20a and the wash water channel element 22a are connected to each other. The channel element 32a of the spray unit 20a and the wash water channel element 22a are connected to each other. The wash water channel element 22a is placed over the channel element 32a of the spray unit 20a.

[0042] To attach the wash water unit 18a to the fastening element 16a, the wash water unit 18a is arranged in the immediate vicinity of the fastening element 16a (see figure). Fig. 3 and Fig. 4) The wash water unit 18a is moved towards the mounting element 16a in a mounting direction 40a facing the mounting element 16a. The wash water unit 18a is moved towards the mounting element 16a in the mounting direction 40a until the wash water unit 18a touches a lateral boundary of the mounting element 16a. To fasten the wash water unit 18a to the mounting element 16a, the wash water unit 18a is moved further in the mounting direction 40a until the wash water unit 18a snaps into place on the mounting element 16a (see Figure 4). Fig. 5).
