Description

The invention relates to a windshield wiper system for a motor vehicle, with at least one wiper blade, which comprises a rider attached to a wiper blade element and an adapter connected to the rider in an articulated manner, which is connected via a receptacle to a component of a wiper arm of the windshield wiper system.

Such a windshield wiper system is, for example, already from the DE 10 2012 021 489 A1 known and comprises at least one wiper blade, which comprises a rider attached to a wiper blade element and an adapter articulated to this rider, which is connected via a receptacle to a component in the form of a box-shaped connecting element of a wiper arm of the windshield wiper system. The adapter is connected to the connecting element via a form-fitting sliding connection until a latching connection of the adapter secures the connection element.

Furthermore, the DE 10 2016 206 127 A1 a wiper device with a wiper arm adapter, which is arranged on a wiper arm that can be driven about a pivot axis, and with a wiper blade adapter, wherein the wiper blade adapter comprises at least one fixing means which is provided for releasably fixing the wiper blade adapter on the wiper arm adapter and wherein the wiper blade adapter comprises at least one securing means which is provided as a safeguard against loss of the wiper blade adapter on the wiper arm adapter in the event of failure of the at least one fixing means. It is provided that the wiper device has at least one operating element which is provided to deflect the fixing means relative to the wiper arm adapter.

The object of the present invention is to create a windshield wiper system of the type mentioned at the outset which, while providing various functions, allows the wiper blade to be changed in a particularly simple and reliable manner.

According to the invention, this object is achieved by a windshield wiper system with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

The windshield wiper system according to the invention comprises at least one wiper blade, which comprises a rider fastened to a wiper blade element and an adapter connected to the rider in an articulated manner. This adapter is connected to a component of the wiper arm of the windshield wiper system via a receptacle, this component according to the invention being a wiper rod of the wiper arm, which is connected to the adapter, for example, via a plug connection. A direct connection of the adapter to the wiper rod of the associated wiper arm has the particular advantage of a particularly simple and cost-effective design, since connecting elements between the wiper rod and the adapter are dispensed with. Rather, the adapter is attached and secured directly to the wiper rod.

Furthermore, it is provided according to the invention that a further functional element is arranged on the wiper rod of the wiper arm separately from the adapter. The functional element is in particular a wind deflector element, by means of which the aerodynamic properties of the respective wiper arm or wiper blade are improved. As an alternative or in addition, this functional element can also be provided for the integration of a window cleaning device in order to create a so-called wet wiper arm. The functional element, which consequently can be designed as a wind deflector and / or a component of the windshield cleaning device and can be attached to the wiper rod separately from the adapter, results in an independent configuration of the adapter and functional element. This has the advantage, for example, that when the wiper blade is replaced, in which the adapter is also disposed of, the functional element in the form of the wind deflector and / or the component of the windshield cleaning device remains on the wiper rod and thus replacing the wiper blade does not have any disadvantages in terms of costs or the Sustainability entails. Rather, due to the separate design of the adapter and the functional element, the functional element remains completely present on the wiper rod.

Furthermore, it is provided according to the invention that the functional element has at least one guide groove and the adapter has at least one guide element corresponding to the guide groove, the guide element engaging in the guide groove in the assembled state of the windshield wiper system. In particular, this enables the wiper blade to be pushed onto the functional element safely. Thus, when the wiper blade is exchanged, the adapter can simply be arranged on the functional element. In particular, a secure arrangement of the wiper blade on the functional element can thus be realized. In this way, it can be prevented, for example, that a misalignment of the wiper blade is recorded on the functional element. In particular at high speeds of the motor vehicle, it can thus be prevented that, for example, the wiper blade can become detached if the wiper blade is incorrectly arranged. Furthermore, aerodynamic disadvantages in the event of a misalignment can also be prevented. In this way, the wiper blade or the adapter can be simply pushed on and held securely on the guide element.

According to an advantageous embodiment, the guide element is designed to be essentially elongated in a direction of longitudinal extension of the adapter and the guide groove is designed to be essentially elongated in a direction of longitudinal extension of the functional element. In particular, the guide groove and the functional element are thus formed in the sliding direction of the adapter or of the wiper blade in the functional element. The guide groove can thus serve as a guide during the entire attachment process. As a result, the adapter can be pushed into the functional element in a simple and yet reliable manner.

It can preferably be provided that the direction of longitudinal extent can be viewed as the direction of longitudinal extent of the wiper blade and essentially also as the direction of longitudinal extent of the functional element. The direction of longitudinal extent is also to be referred to in particular as the insertion direction.

It is also advantageous if the adapter has at least two guide elements and the functional element has at least two guide grooves. This embodiment enables, in particular, a particularly reliable hold and a particularly simple insertion of the wiper blade or the adapter into the functional element. In this way, for example, tilting of the adapter relative to the functional element during the insertion process can be prevented in an improved manner. A more reliable exchange of the wiper blade with the adapter on the functional element can thus be realized.

It has also proven to be advantageous if the at least two guide elements are formed on opposite sides of the adapter and the at least two guide grooves are formed on opposite sides of the functional element. This embodiment makes it possible, in particular, that tilting of the adapter relative to the functional element during the insertion process can be prevented in a particularly advantageous manner.

Furthermore, it has proven to be advantageous if the at least two guide elements have a different shape and the at least two guide grooves have a different shape. This enables a user to easily see in which direction or in which position the wiper blade can be pushed into the functional element. A misalignment of the wiper blade on the functional element can thus be reliably prevented.

According to a further advantageous embodiment, the at least one guide element is arranged on a side of the adapter that is opposite to the side on which the wiper blade element is arranged on the adapter. In particular, the guide element with the corresponding guide groove can thus be referred to as an internal guide. A simple production of the guide element can thereby be realized.

It is also advantageous if the at least one guide element is formed on a side of the adapter that is formed orthogonally to the side on which the wiper blade element is formed on the adapter. In particular, the guide element is thus formed on the side of the adapter. The leadership can be referred to as external leadership. As a result, a simple process of inserting the adapter into the functional element can be implemented.

In a further advantageous embodiment, the at least one guide element is essentially wedge-shaped, and the guide groove is essentially designed as a wedge-shaped receptacle. In particular, this can prevent the adapter from moving in the functional element. The wedge shape thus serves as an additional fastening device during the insertion process and in the inserted state, so that the adapter can be prevented from “falling out” of the functional element. In particular, the guide element can be designed in the shape of a dovetail. Furthermore, reliable guidance of the adapter in the functional element can thereby be realized during the insertion process.

Furthermore, it has proven to be advantageous if the functional element is designed as a wind deflector. In particular, the functional element can serve both as a wind deflector and as part of the window cleaning device. A combination of these two functions has the particular advantage that the wind deflector function also allows cleaning liquid to be applied to the pane to be cleaned in a particularly favorable manner and in the slipstream of the wind deflector. In addition, the dual function of the functional element both as a wind deflector and as part of the window cleaning device has the advantage of dual use, so that the corresponding component can be manufactured particularly easily and inexpensively. In particular, it can thus be provided that a window cleaning device is also integrated into the functional element.

The invention also includes a motor vehicle which includes the windshield wiper system. The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger vehicle or truck, or as a passenger bus or motorcycle.

The invention also comprises the combination of the features of the described embodiments.

The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention which are to be considered independently of one another and which also further develop the invention in each case independently of one another. Therefore, the disclosure is intended to include combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention that have already been described.

In the figures, the same reference symbols denote functionally identical elements.

the 1a , 1 b and 1c show, in a respective perspective view, an assembly sequence for the arrangement and fixing of a functional element explained in more detail below 1 on a wiper arm 2 . The wiper arm 2 and the functional element 1 are here in 1a initially shown explosively separated.

It can be seen in particular that the wiper arm 2 a wiper rod 3 includes which in a kink area 4th Is formed at an angle. On one free end 5 opposite side is the wiper rod 3 with a pen box 6th firmly connected, which is a connection area 7th at least substantially rectangular in cross section and on the wiper rod which is also at least substantially rectangular in cross section 3 is crimped. The pen box 6th is about bearing openings 8th articulated to a lever element, not shown, of the windshield wiper system, which is sometimes also referred to as a fastening part, which in turn is connected non-rotatably to an associated drive shaft of a drive motor. To those through the storage openings 8th formed axis is the wiper arm 2 relative to the associated lever element can be pivoted against the spring force of a spring element, which in turn is in a spring receptacle 9 at the corresponding end of the wiper rod 3 can be hung, for example, in the operating position Wiper arm 2 or to press an associated wiper blade against the surface of a windshield.

The functional element 1 has a first sub-area 10 and a second portion formed integrally therewith 11 on, within which a continuous recording channel 12th for the wiper rod 3 is provided. The recording channel 12th is in cross section at least substantially on the approximately rectangular cross section of the wiper rod 3 adapted, which has an at least substantially uniform cross section over its entire course. As a result, the receiving channel also has 12th over its entire length within the functional element 1 a substantially uniform cross-section.

As in the following in conjunction with the 1b and 1c is recognizable, is the functional element 1 consequently from the free end 5 on the wiper rod 3 can be attached or pushed on until one end 13th of the first sub-area 10 of the functional element 1 at least essentially flush with the connection area 7th of the pen box 6th connects. This means that the functional element is plugged on 1 on the wiper rod 3 up to the pen box 6th can be done is the functional element 1 in the first sub-area 10 - starting from the end 13th - at least over the kink area 4th made away from an elastic material, for example a corresponding plastic. Due to this soft elastic material, it is possibly also conceivable that the connection area 7th of the pen box 6th sleeve-like from the end 13th of the sub-area 10 of the functional element 1 is towered over.

The end 13th of the sub-area 10 is also surmounted by a pipe section 14th over which the functional element 1 can be supplied with a window cleaning fluid in a manner which will be described in more detail below. Within the line part 14th is therefore at least one supply channel 15th designed for windshield cleaning fluid, over which the functional element 1 can be supplied with window cleaning fluid in a manner which will be described in more detail below. This supply channel 15th also extends over the sub-area 10 as well as over the sub-area 11 of the functional element 1 . As a result, it is in the functional element 1 a window cleaning device 16 or a part of this is formed, so that in the present case it is the wiper arm 2 is a so-called wet wiper arm. This means that by means of the windshield wiper system 49 The window to be cleaned, in particular the front window of the motor vehicle, can be acted upon with window cleaning fluid via nozzles, which liquid is supplied by the wiper arm 2 are worn. The end of the line part 14th of the functional element 1 is connected to one of the windshield cleaning systems for windshield cleaning fluid together with the associated pump via a channel arrangement (not shown further). Usually this is accommodated in the front space or engine compartment of the motor vehicle. Like in particular from 1c is recognizable, the line part runs 14th in the present case, the underside of the wiper rod 3 to the inside of the pen box 6th Further.

Looking at the 1a until 1c it can also be seen that the sliding of the functional element 1 on the wiper rod 3 so far that this is done - like this 1c in the final assembled position of the functional element 1 is recognizable - at a free end 5 over a considerable length range from the receiving channel 12th protrudes. Conversely, this means that the functional element 1 with the sub-areas 10 , 11 via the recording channel 12th with one from the free end 5 the wiper rod 3 spaced length range of the wiper rod 3 connected is.

In other words, the free end protrudes 5 over the sub-area 11 of the functional element 1 out or out of the receiving channel 12th out.

The in the functional element 1 integrated window cleaning device 16 In the present case, it comprises a channel system with a respective one in the functional element 1 integrated channels which open out to various nozzles via which the window to be cleaned or to be wiped or the associated wiper blade, which will be explained in more detail below, can be exposed to window cleaning fluid.

So includes the window cleaning device 16 initially two outer circle nozzles 17th , 18th , via which the wiper blade is acted upon in the vicinity of its outer circle, that is to say that area in which the wiper blade runs through the largest radius of its surface to be wiped. The outer circle nozzle 17th covers one about the functional element 1 closer area and the outer circle nozzle 18th one of the functional element 1 even more distant area near the outer circle of the corresponding wiper blade.

In addition, the window cleaning device comprises 16 a plurality of the present five central nozzles 19th , which are all at least essentially in a row along the direction of extent of the functional element 1 extend. The respective nozzles 19th are in the manner still to be described in each case associated with the functional element 1 or from the wiper arm 2 protruding humps in the direction of the pane to be wiped and cleaned 20th housed. Finally, the Window cleaning device 16 at least one inner circle nozzle 21 over which the wiper blade of the wiper arm 2 is supplied with cleaning fluid in the area of its inner circle, in which the wiper blade runs through its shortest radius of the corresponding wiping surface during the wiping process. All nozzles 17th , 18th , 19th and 21 can be set in such a way that this occurs during a starting movement, i.e. in the case of a windshield during an upward movement of the respective wiper arm 2 , apply the cleaning liquid to the windshield, in particular the windshield, at a corresponding distance in front of the wiper blade moving there. If necessary, the wiper blade can also be acted upon directly by the windshield cleaning fluid.

In addition to the integration of the window cleaning device 16 includes the functional element 1 the further function of wind deflection. As a result, the functional element is 1 in the present case as a wind deflector 22nd formed and comprises on the at least substantially the nozzles 19th as well as the wiper rod 3 facing away from the front or top side a wind deflector contour 23 In order to consequently allow a particularly favorable overflow of the wiper arm, which is usually from the front 2 or to allow air flowing on the corresponding wiper blade.

The present functional element 1 is therefore used as a wind deflector 22nd and for the integration of the window cleaning device 16 educated. However, it is to be considered within the scope of the invention that the functional element 1 could also only perform one of these two functions.

2a shows the functional element in a schematic perspective view 1 when attached with a wiper blade 34 or a wiper blade element 35 . In the following exemplary embodiment it can be seen in particular that an adapter 37 a guide element 42 , 43 is trained. On the functional element 1 are in particular corresponding guide grooves 40 educated. In particular, the adapter 37 reliably on the functional element 1 be pushed. In other words, it is provided that the functional element 1 at least one guide groove 44 and the adapter 37 at least one to the guide groove 34 corresponding guide element 42 , 43 having, in the assembled state of the windshield wiper system 49 the guide element 42 , 43 into the guide groove 44 intervenes.

Furthermore, the 2a that the guide element 42 , 43 in a longitudinal direction L of the adapter 37 is essentially elongated and the guide groove 44 in a longitudinal direction L of the functional element 1 is essentially elongated.

2 B shows the functional element 1 with the wiper blade 34 according to 2a when not plugged together. In particular, shows the 2 B how particularly simple the wiper blade 34 with the adapter 37 for example can be exchanged. In particular, only the wiper blade 34 with the adapter 37 of the functional element 1 can be removed and replaced with a new one, for example. the 2a until 2 B also show the functional element in respective detail and perspective bottom views 1 the in the 1a until 1c described embodiment. From the 2a and 2 B is in particular the receiving channel for the wiper rod 3 recognizable which of a third sub-area 24 of the functional element 1 , which with the sub-areas 10 and 11 is also formed in one piece.

Based on a synopsis of the 2a and 2 B it can also be seen that in the present case the functional element 1 by means of a fastening device 25th in the direction of extent of the receiving channel 12th secured to the wiper rod 3 of the wiper arm 2 is arranged. In the present case, it is secured by means of a tab 26th which has a film hinge 27 pivotable on the functional element 1 is arranged. Will the tab 26th by means of a locking element 28 into a locking receptacle provided for this purpose 29 in the area of the receiving channel 12th inserted, so comes the locking element 28 also with a groove 30th ( 1a) inside the wiper rod 3 engaged. This virtually results in an axial securing of the functional element 1 on the wiper rod 3 so that the functional element 1 after sliding it onto the wiper rod 3 is secured accordingly.

3a shows a schematic perspective view of the functional element 1 , in particular a partial view is shown. In the following exemplary embodiment it is shown in particular that the at least one guide element 42 , 43 on one side on which the wiper blade element 34 on the adapter 37 is arranged opposite side 45 of the adapter 37 is arranged. Furthermore, it is shown in particular that the at least one guide element 42 , 43 is wedge-shaped, in particular dovetail-shaped, and the guide groove 44 is also essentially wedge-shaped. In particular, more degrees of freedom can be restricted by the dovetail-shaped connection and the connection cannot loosen.

3b shows a further schematic perspective view, as already in FIG 3a shown. In the following embodiment is in particular shown that the adapter 37 at least two guide elements 42 , 43 , in particular a first guide element 42 and a second guide element 43 has and the functional element 1 at least two guide grooves 44 having. It can be provided in particular that the at least two guide elements 42 , 43 on opposite sides 46 , 47 , in particular the first guide element 42 on a first page 46 and the second guide element 43 on a second side 47 are formed and the two guide grooves 44 on opposite sides 48 of the functional element 1 are trained. It can also be seen in particular that the at least two guide elements 42 , 43 have a different shape from one another and the at least two guide grooves 44 also have a different shape. This enables a particularly simple and reliable insertion of the adapter 37 in the functional element 1 will be realized.

The fastening device 25th is in the 4a and 4b in a respective sectional view of the arrangement of the functional element 1 on the wiper rod 3 explained again in their mode of operation. It can be seen in particular how the locking element is secured axially 28 on the side of the flap 26th within the locking receptacle 29 or at the groove 30th the wiper rod 3 results.

From the 5a and 5b it is also clear from the different hatching that the functional element 1 in the present case is produced as a plastic part in a two-component process. In particular, it can be seen here that the receiving channel 12th in the area of the fastening device 25th by a hard component 31 is formed. Likewise, the respective channels - carrying the cleaning fluid - are in the second and third sub-areas 11 , 24 of the functional element 1 from this hard component 31 - at least in the area of the respective nozzles 17th , 18th , 19th , 21 educated. In between, parts can also be made using a soft component 32 of the plastic are formed, which incidentally also - as already explained - the first sub-area 10 and the line part 14th form. Through the soft component 32 is also - like this from the 4a and 4b is recognizable - the wind deflector contour 23 of the functional element 1 educated. The components 31 , 32 are particularly designed to be UV-resistant in order to be durable accordingly.

In the 5a and 5b is an alternative embodiment of the functional element in a respective perspective view 1 shown. This functional element 1 is essentially identical in its design and function to that according to the first exemplary embodiment described, so that only the differences will be discussed below.

This functional element is essentially different 1 in that this is the first sub-area 10 of the functional element 1 , which is between the second sub-area 11 and the connection area 7th of the pen box 6th extends, is not provided here. Rather, the functional element ends 1 with an end 33 at a distance in front of the kink area 4th and consequently at a considerable distance in front of the connection area 7th of the pen box 6th . The line part 14th of the functional element 1 consequently extends over a considerable length without additional sheathing of the wiper rod 3 below or inside from this to the pen box 6th into, from where the further connection for the supply of the cleaning fluid is made.

Depending on how short the functional element 1 is formed, can optionally in some embodiments on one or more respective inner circle nozzles 21 be waived. Such a configuration results, for example, in vehicles of the compact class, in which a relatively small window area needs to be wiped or cleaned. Such a concept may also be suitable on a respective passenger side of a larger pane. Incidentally, the points in the functional element 1 integrated window cleaning device 16 one to the one already related to the 1a until 4b embodiment described at least substantially identical configuration. However, depending on the length of the functional element 1 or in particular the sub-areas 11 and 24 - a smaller number of middle nozzles 19th be provided. The latching element is also in the present exemplary embodiment 28 recognizable by means of which the functional element 1 after attaching it to the wiper rod 3 can be secured.

In the 6a and 6b is finally the assembly of the wiper blade in a respective perspective view 34 at the corresponding free end 5 the wiper rod 3 , which from the recording channel 12th of the functional element 1 protrudes, shown. The wiper blade 34 includes the wiper blade element 35 , on which a base body in the form of a rider 36 is attached. This rider 36 is in turn articulated with the adapter 37 connected so that the wiper blade element 35 with the rider 36 relative to the adapter 37 can be pivoted within certain limits. The adapter 37 comprises a receptacle which is at least partially open in the present case 38 over which the adapter 37 or thus the entire wiper blade 34 at the free end 5 the wiper rod 3 can be attached. This is the recording 38 , which is designed as a kind of plug-in receptacle, in its cross-section or in its shape on the cross-section of the wiper rod 3 Voted. After the adapter 37 with the recording 38 over a certain length range on the free end 5 the wiper rod 3 is attached, a locking device comes 39 engaged, which both on the part of the adapter 37 as well as on the side of the wiper rod 3 comprises a corresponding latching element. This locking device 39 can for example on the part of the adapter 37 comprise a locking pin or the like, which with a locking recess on the side of the free end 5 the wiper rod 3 comes into engagement. The locking device 39 is by means of an actuating element 40 releasable in the form of a push button or the like, which in the present case in the direction of the wiper blade element 35 must be pressed.

In its locked position, this actuating element protrudes 40 a through opening 41 within the sub-area 24 of the functional element 1 . In the locked position of the locking device 39 is thus the actuator 40 at least substantially within this through opening 41 arranged and can therefore be operated from the front outside to the wiper blade 34 from the free end 5 the wiper rod 3 to decrease.

As the functional element 1 in one from the free end 5 spaced length range of the wiper rod 3 is attached to this and the adapter 37 of the wiper blade 34 at the free end 5 the wiper rod is attached, results for the functional element 1 and the wiper blade 34 a completely independent respective arrangement and fixation on the wiper rod 3 . This has the advantage that the wiper blade 34 completely independent of the functional element 1 can be removed and, for example, replaced from time to time without this affecting the functionality of the functional element 1 Has. In particular, it must be taken into account that both the wind deflection function and the window cleaning function of the functional element 1 remains completely intact, even if the adapter 37 is removed, the functional element 1 but on the wiper rod 3 remains. In contrast to other systems, this means that the wiper blade is replaced 34 not a part of the wind deflector device or the windshield cleaning device is removed and disposed of, for example, which raises corresponding financial and sustainability problems. Rather, a system is created in which the connection of the wiper blade 34 and the connection of the functional element 1 as well as the implementation of the by the functional element 1 accomplished functions are completely independent of each other.

In the functional element 1 further elements can also be integrated. In particular, a heater for the window cleaning device can also be used 16 be integrated. Here, too, there are those already in connection with the window cleaning device 16 described advantages.

Overall, the examples show how the invention provides a windshield washer system 49 can be provided in which the functional element 1 and the wiper blade 34 completely independent of each other on the wiper rod 3 can be arranged and fixed.
