    [0001] The present invention relates to a connection arrangement for connecting a wiper blade to a wiper arm of a vehicle's wiper system. The connecting arrangement includes a connecting element made to support the wiper blade, which can be fitted to the wiper arm in a mounting direction that runs transversely to a definable cleaning surface. cleaning movement of the windscreen wiper brush. At least one fixing element of the connection arrangement is used to securely support the connection element on the wiper arm. In addition, the invention relates to a method for connecting a wiper brush to a wiper arm of a vehicle's wiper system.
    [0002] DE 691 01 340 T2 describes an articulated connection between a wiper arm and a wiper blade. In the wiper arm, which has a transversal U profile, an opening is provided to receive a tongue that can be moved along the wiper arm. If the tongue is moved beyond the free end region of the wiper arm, that is, backwards, a groove provided in the tongue releases a pivot axis that joins two longitudinal walls of a mandrel. The mandrel is pressed into an opening that is carried out on a main windshield brush holder, the clamps formed on the mandrel engaging in notches made on the main holder.
    [0003] DE 101 30 903 A1 describes a wiper arm of a vehicle wiper system, the end region of which has a transverse U profile that is opened downwards. An adapter that supports a wiper blade can be inserted, from below, into the end region of the wiper arm, that is, in a mounting direction that runs perpendicularly to a cleaning surface that can be defined by the wiping brush cleaning movement. In the side walls of the adapter, notches are provided whose internal dimensions correspond to the external dimensions of the projections that project in a lateral and internal direction in relation to the wiper arm members. When the adapter is inserted into the end of the windscreen wiper arm in the direction of assembly, the projections then move along the notches. To lock the adapter in relation to the wiper arm, the adapter is moved along with the wiper brush towards an open end region of the wiper arm and the arm projections windscreen wipers extend to the hitch notches provided on the adapter. A latching tongue arranged on the adapter is inserted into a notch on the wiper arm in this fixed position of the adapter and thus indicates that the adapter has reached its operational position.
    [0004] DE 10 2008 011 449 A1 also describes a connection between a wiper blade and a wiper arm via an adapter on the wiper blade, which is inserted from below into a region of the wiper arm end. The adapter is then moved laterally together with the wiper brush towards an end region of the wiper arm in order to lock the adapter in relation to the wiper arm. windshields and thus placing the adapter in a functional position.
    [0005] The fact that fixing the adapter in its position in relation to the windscreen wiper arm requires complicated handling of the adapter should be seen as a disadvantage of this type of connection arrangements.
    [0006] DE 10 2005 016 485 A1 describes a device for connecting a wiper blade to a wiper arm of an articulated wiper system. The end region of the windscreen wiper arm is made in the form of a body open downwards, in the form of a parallelepiped and hollow with two projections towards the interior from its side walls. An adapter to support a wiper blade consisted of two hitch tongues that engage with the two projections when the adapter is pushed from the bottom into the hollow body on the wiper arm. Another projection formed on a side wall of the hollow body and projecting inwards engages a depression in the adapter. In this way, the adapter is held in a fixed position in the end region of the wiper arm.
    [0007] This type of connection arrangement is comparatively more complex, and it is also quite difficult to remove the adapter and with it the wiper blade from the wiper arm.
    [0008] It is an object of the present invention to produce a connection arrangement of the type specified above and a corresponding method that allows a particularly simple and functionally reliable connection of a wiper blade to a wiper arm. windshield wipers.
    [0009] This objective is achieved through a connection arrangement and through a method with the characteristics indicated in the present invention. Advantageous variants with convenient improvements of the invention are specified in the embodiments.
    [00010] The connection arrangement according to the invention for connecting a wiper brush to a wiper arm of a vehicle's wiper system includes a connecting element designed to support the wiper blade. The connecting element can be attached to the wiper arm in a mounting direction that runs transversely to a cleaning surface that can be defined by the wiper brush cleaning movement. A fixing element for the connection arrangement, which serves to securely attach the connection element to the wiper arm, is made in the form of a sliding device arranged on the wiper arm and with a profile transverse U, which can be moved along the windscreen wiper arm from a mounting position to a functional position, securing the connecting element. A particularly simple and functionally reliable connection of the wiper blade is achieved by the fact that the connecting element does not have to be moved together with the wiper blade from the mounting position to the functional position in order to attach the wiper blade to the wiper arm. Instead, the connecting element remains in its mounting position, while only the sliding device is moved along the wiper arm in order to secure the connecting element and prevent it from working freely and free from the windscreen. wiper arm. This facilitates the handling of the windscreen wiper brush when installing or removing it on the wiper arm.
    [00011] In this case, the sliding device has a backrest and two members, at least one projection that engages around the wiper arm on the bottom side is arranged on the members of the sliding device. This type of sliding device provides protection against impact in the event that the wiper arm without a wiper blade strikes the windscreen, for example due to a carelessness of the mechanic after brush removal windscreen wiper arm. Protection against impacts of this nature is particularly effective if the wiper arm is metallic and if the sliding device is made of a flexible material such as plastic. The sliding device, which engages around the wiper arm on the underside, also ensures that the sliding device runs particularly smoothly along the wiper arm.
    [00012] A wiper blade with the connecting element is fitted to the wiper arm in a particularly simple and intuitive manner by a mechanic, ensuring a high degree of reliability against incorrect assembly. To remove the wiper blade, the sliding device only has to be moved from the functional position by fixing the connecting element in the mounting position, then the connecting element, and with it the wiper brush. windshields, can be removed from the wiper arm in the opposite direction to the mounting direction.
    [00013] As a pressure force is applied, which presses the windscreen wiper brush against the windscreen, the wiper arm whenever the wiper brush is in the the vehicle's windscreen, the wiper arm can also reliably move the wiper blade over the windscreen if the slide device is in the mounting position and not in the functional position. This applies even if the sliding device is defective, so that it does not fix the connecting element as desired, even in the functional position.
    [00014] The described connection arrangement can also be produced with a reduced size connection element. This fact is advantageous, since only a reduced amount of water is released by the connection element on the vehicle's windshield, and the connection element requires less structural space, even if it is raining or the washing liquid is falling on the windshield.
    [00015] In an advantageous variant of the present invention, an end region of the sliding device extends beyond the end region of the wiper arm in the mounting position. As a result, a mechanic can easily check whether the sliding device is in the mounting position or in the functional position by securing the connecting element.
    [00016] It is also advantageous if the wiper arm has at least one coupling notch arranged in the sliding device in the functional position and / or in the mounting position of the sliding device. This is because the engagement of the engagement nose with the engagement notch is visibly noticeable and can be heard and felt. In this way, the mechanic can be informed that the sliding device is in the functional position or in the assembly position. It is particularly favorable if one and the same coupling nose engages with a first coupling notch in the functional position and a second coupling notch in the mounting position. However, alternatively, only a hitch notch can also be provided, which will receive one of the two positions. The windscreen wiper arm can also have the hook nose and the sliding device the hook notches.
    [00017] In another advantageous variant of the present invention, the wiper arm has a transverse U profile at least in the region of the connecting element, with a rear part of the wiper arm being A through opening is arranged in which a corresponding projection of the connecting element is received in the mounting position. If the projection, whose external dimensions correspond to the internal dimensions of the through opening, is received in the through opening, then it is ensured that the connecting element, and with it the windscreen wiper brush, cannot move in the direction of the longitudinal extension of the wiper arm or transversely in relation to this direction of the longitudinal extension. In other words, the connecting element, and with it the windscreen wiper brush, are fixed in their positions on the plane of the cleaning surface by said adjustment of the projection and the corresponding passage opening. The mechanic can also verify, when the projection passes through the through opening, that the connecting element is in the correct mounting position in which the sliding device can be moved to the functional position by securing the connecting element.
    [00018] If the projection and the opening of the passage have a shape other than the circular shape, for example, if the projection and the opening of the passage have an oval or angular shape, in particular a rectangular or square shape, when placing the projection engaged in the passage opening, the connecting element can also be fixed against rotation in relation to the wiper arm.
    [00019] At least part of the projection region preferably has a profile similar to the profile of a notch provided in the sliding device, with at least part of the projection region adjoining the notch in the functional position of the sliding device. In this way, when placing the sliding device against a part of the projection region, it is possible to visually check whether the sliding device has reached the functional position. This is not the case if there is a gap between the profile that delimits the notch in the sliding device and the profile of part of the projection region.
    [00020] It proved to be even more advantageous if the passage opening and the projection corresponding to it are specifically executed to a place where the wiper arm is attached to the vehicle. For example, the geometry of the passage opening and the projection of a wiper arm on the driver's side and the associated wiper blade may differ from the geometry of a wiper arm and the windscreen wiper attached to the passenger side. Specific opening and projection geometry can also be provided for a wiper arm for a right-hand or left-hand vehicle to ensure that only the wiper blade is effectively can be attached to the windscreen wiper arm provided. Such protection against inadvertent confusion can also be provided in order to be able to distinguish the wiper arm and the wiper brush from a rear window wiper from a wiper arm. windscreen wipers and wiper blades from a front wiper.
    [00021] It is also advantageous if the sliding device includes a front wall through which an open end region of the wiper arm can be closed at least partially in the functional position. Thus, the sliding device protects the connecting element received in the end region of the wiper arm and, at the same time, provides a visually attractive end region in the end region of the wiper arm. The front wall that encloses the windscreen wiper arm at the front, that is, in the direction of its longitudinal extension, also protects the windscreen to a great extent in the case of the brushless wiper arm windshield wipers accidentally fall on it.
    [00022] In order to achieve a particularly secure fixation of the connecting element on the windscreen wiper arm in the mounting position, measures can be taken, according to an even more advantageous variant of the present invention, so that the arm of the windscreen windshield wipers have at least one notch open in the direction of assembly performed to receive a corresponding projection formed on the connecting element.
    [00023] It proved to be even more advantageous if the connecting element included a lower part that supports the wiper blade and an upper part fixed on the wiper arm in the functional position, the lower part being maintained in relation to the upper part, in order to be able to move in the latter. As a result, the windscreen wiper brush can be adjusted to the course of the windscreen surface when the windscreen, typically with a spherical curve, is being cleaned. Bearing in mind that the parts that allow a relative movement between the wiper arm and the wiper blade are susceptible to wear and are parts of the connecting element, these are also replaced when replacing the brush of the windscreen wiper together with the connecting element. This ensures that the relative movement between the wiper blade and the wiper arm remains smooth.
    [00024] The upper part is preferably executed in the form of a rocker which is rotatably supported on a pin or bearing pin which is inserted through a through opening in the lower part. Such a support from the top to the bottom ensures a particularly regular relative movement between the wiper arm and the wiper blade.
    [00025] At least one stop formed at the bottom preferably limits the relative movement of the top in relation to the bottom. This is because the stops can be used to limit the relative movement of the wiper blade relative to the wiper arm in a particularly simple way to the desired level.
    [00026] If the windscreen wiper arm, according to an even more advantageous variant of the present invention, is leaning against the upper side walls in the functional position, this fact also ensures a particularly secure attachment of the connecting element to the windscreen wiper arm against rotation.
    [00027] Finally, it has been shown to be advantageous if the sliding device and / or the wiper arm have a notch made to receive a component of the wiper brush if it moves in relation to the wiper arm clean windshields. As a result, the sliding device and the wiper arm can be closed to a great extent, visually and acoustically, and the relative movement of the wiper brush in relation to the wiper arm. windshield is still possible thanks to the notches.
    [00028] In the method according to the present invention, to connect a wiper blade to a wiper arm of a vehicle's wiper system, a connecting element made for holding the wiper blade in place on the wiper arm in a mounting direction that runs transversely in relation to the cleaning surface defined by the wiper brush cleaning movement. By means of at least one fastening element, the connecting element is held securely in the windscreen wiper arm. In this case, as a fastening element, a sliding device arranged on the wiper arm and with a transverse U-profile is moved along the wiper arm from a mounting position to a functional position, fixing the connecting element.
    [00029] The advantages and preferred variants described in relation to the connection arrangement according to the present invention are also applicable to the method according to the invention.
    [00030] The characteristics and combinations of characteristics specified in the description above and the characteristics and combinations of characteristics specified in the description of the figures and / or in the figures below can be used not only in the combination specified in each case, but also in other combinations or in isolation without thereby departing from the scope of the present invention.
    [00031] Other advantages, characteristics and details of the invention can be seen in the embodiments, in the following description of preferred exemplary variants and by reference to the drawings. The following can be seen in the drawings: Fig. 1 Part of a wiper arm of a vehicle wiper system with a wiper blade attached to the wiper arm windshield, in which a sliding tongue secures an adapter that supports the wiper blade; Fig. 2 Windshield wiper brush according to Fig. 1, with the adapter that includes a rocker arm and a support; Fig- 3 Wiper arm and slide tongue removed from the wiper arm in perspective; Fig- 4 Slide tab seen from below; Fig- 5 Exploded representation of the adapter components; Fig- 6 View from below an adapter holder received in an end region of the windshield wiper arm, fixed in its position by means of the slide tab moved to its functional position; A Fig- 7 The windshield wiper arm, with its sliding tab moved forward, to a removal position, in which the adapter can be removed from the end of the windscreen wiper arm by pulling low; Fig. 8 View from below the end region of the wiper arm with the support received in it, in which the slide tab is moved to the removal position shown in Fig. 7; Fig. 9 Adapter removed from below the wiper arm end region and supporting the wiper brush, and the wiper arm with the slide tab in its removal position; Fig. 10 Lateral perspective of the wiper arm with the wiper brush supported on it; e Fig. 11 Alternative design of a wiper arm with a wiper brush arranged on it, which is supported by a specific adapter for the wiper arm.
    [00032] Fig. 1 shows part of a wiper arm 12 and a wiper brush 14 of a vehicle wiper system 10. Of the adapter 26 (cf. Fig. 2) which is received in the end region of the windscreen wiper arm 12 performed as the receiving region, Fig. 1 shows only a lower part executed as a support 16, which engages around spring bands 18 of the wiper brush 14 and therefore supports the wiper brush 14. The wiper brush 14 also includes a spoiler20 and a rubber (no shown in Fig. 1) to clean a windshield (also not shown) of a vehicle.
    [00033] In order to hold the adapter 26 firmly on the wiper arm 12, a sliding tongue 22 is arranged on the wiper arm 12 which is in turn supported so that it can be moved in a direction of the longitudinal extension of the windscreen wiper arm 12. The arrow symbol 24 applied to the slide tab 22 in the form of a double arrow indicates the directions in which the slide tab 22 can be moved in relation to the wiper arm. windscreen 12.
    [00034] In a functional position of the slide tab 22 shown in Fig. 1, the latter ensures that the adapter 26 (cf. Fig. 2), and with it the wiper blade 14, cannot be removed from the windscreen wiper arm 12. In this functional position of the sliding tongue 22, a notch 28 provided on the sliding tongue 22 and with a semicircular profile, is leaning against a cylindrical partial region 30 of a projection 32 projecting upwards on a rocker body 34 of adapter 26 (cf. Fig. 2).
    [00035] Fig. 2 shows the rocker 34 executed in the form of the upper part of the adapter with several parts 26, without the slide tongue 22 hiding the rocker 34. The rocker 34 is supported on a bearing pin in the form of pin 36 which is pushed through a through opening 38 provided in support 16 (cf. Fig. 5). Ribs can be provided in the through opening 38 in order to secure the bearing pin 36 so that it cannot rotate (cf. Fig. 5).
    [00036] If the wiper blade 14 is received in the end region 40 of the wiper arm 12 through the adapter 26 that supports the wiper brush 14, it is inserted from from below in the end region 40 of the wiper arm 12 which is opened downwards (cf. Fig. 9). For this purpose, the slide tab 22 is firstly moved to an assembly position shown in Fig. 9 and allowing the adapter 26 to be mounted, which is also a removal position that allows the adapter 26 to be removed.
    [00037] As can be seen in Fig. 3, the end region 40 of the wiper arm 12 has a transverse U-profile that includes a backrest 42 and two members 44 that extend downwards from the backrest 42. Each of the members 44 has two notches open downwards 46 which, if the adapter 26 is placed in the end region 40, receive two spikes 48 that extend beyond the side walls 50 of the rocker 34 (cf. Fig. 2 ).
    [00038] If the four posts 48 are received in the corresponding four notches 46 in the two members 44 of the end region 40 of the wiper arm 12, adapter 26 cannot move in the direction of the longitudinal extension of the wiper arm windscreen wipers 12. The projection 32 of the rocker arm 34 then passes through a through opening 52 made in the rear 42 of the wiper arm 12. Another notch 86 in the rear 42 of the wiper arm windshield 12 serves to receive an elevation 88 of the support 16 that the latter has in the region of the passage opening 38 (cf. Fig. 3 and Fig. 5).
    [00039] If adapter 26 is inserted in the end region 40 of the wiper arm 12, the side walls 50 of the rocker 34 are abutted against the inner sides of the members 44. As a result, adapter 26 is also attached to the wiper arm 12 in a transverse direction in relation to the direction of the wiper arm extension 12, ie in a transverse direction in relation to the direction of the longitudinal extension of the wiper blade 14.
    [00040] In addition, the slide tab 22 also ensures that the adapter 26 cannot move out of the receiving region 40 of the wiper arm 12 in an upward direction, that is, perpendicular to the definable cleaning surface by the wiping brush cleaning movement 14.
    [00041] For this purpose, as shown in Fig. 4, two rails 56 are arranged on the respective side walls 54 of the sliding tongue 22 which also have a transverse U profile, these rails 56 projecting inwards from a inner side of the respective side wall 54. These rails 56 engage around the wiper arm 12 in the end region 40 on the bottom side and therefore serve, in collaboration with a backrest 58 that connects the side walls 54 of the sliding tongue 22 (cf. Fig. 3), as a guide for the translational movement of the sliding tongue 22 in relation to the wiper arm 12.
    [00042] The spikes 48 received in the notches 46 of the wiper arm 12 also rest on the rails 56 of the slide tongue 22 of which the latter is moved to its functional position shown in Fig. 1, that is, in this case, back.
    [00043] A region 60 between the two rails 56 and a region between the rear rail 56 and a hitch nose 64 also designed for the interior from the side wall 54 make it possible when the slide tab 22 is moved to the mounting position, take the posts 48 of the rocker arm 34 to the notches 46 provided on the side walls 44 of the wiper arm 12 by inserting the adapter 26 from below in the end region 40 of the wiper arm windshields 12.
    [00044] The hitch noses 64 projecting inwards from the side walls 54 of the slide tongue 22 can be inserted in the front hitch notches 66 or in the rear hitch notches 68 that are made in the two members 44 of the arm windscreen wipers 12 in the end region 40 thereof. If the respective hitch nose 64 is located in the front hitch notch 66, then the slide tongue 22 projects forward over the end region 40 of the wiper arm 12 and a front wall 70 of the slide tongue 22 is spaced from the end region 72 of the wiper arm 12 (cf. Fig. 3, Fig. 4 and Fig. 8).
    [00045] If, on the other hand, the sliding tongue 22 is moved backwards, the coupling nose 64 is then located in the rear coupling notch 68 (cf. Fig. 6), so that the front wall 70 of the sliding tongue 22 is leaning against the front end region 72 of the wiper arm 12. A mechanic working on the sliding tongue 22 can clearly hear and feel, that is, check by touching, whether a nose coupling 64 is engaged with the front coupling notch 66 or the rear coupling notch 68.
    [00046] Another visual indication that the mounting position of the slide tab 22 has been reached which allows the mounting or removal of the adapter 26 from the end region 40 of the wiper arm 12 is shown by the position of the partial region 30 The partial region 30, which emerges over the passage opening 52 at the rear 42 of the wiper arm 12, is abutted to the notch 28 provided on the slide tongue 22 if the coupling nose 64 is in the coupling notch. rear 68 (cf. Fig. 1 and Fig- 6).
    [00047] If, on the other hand, the sliding tongue 22 is pushed forward, then the coupling nose 64 is located in the front coupling notch 66 (cf. Fig. 8). The rear hitch notch 68 is then released and there is a space between the partial region 30 of the projection 32 and the notch 28 at the rear 58 of the slide tongue 22 (cf. Fig-7).
    [00048] Fig. 6 shows the slide tongue 22, which supports the rocker 34, moved to its functional position, in which the spikes 48 arranged on the side walls 50 of the rocker 34 rest on the rails that project into the interior 56 of the sliding tongue 22. In the functional position, the coupling nose 64 formed on the sliding tongue 22 is engaged with the rear coupling notch 68 which is located on the member 44 of the wiper arm 12. On the other hand, the notch front hitch 66 is free.
    [00049] In contrast, in the mounting position or in the removal position of the slide tab 22 shown in Fig. 7, the latter is moved forward and the rear hitch notch 68 is free while the hitch nose 64 is inserted in the front hitch notch 66. The cylindrical partial region 30 of the projection 32 of the rocker 34 is spaced in relation to the semicircular notch 28 at the rear 58 of the slide tongue 22.
    [00050] The cylindrical partial region 30 may, as presented by way of example in this case, for greater clarity, have an emblem 74, for example, an emblem of a mark, which stands out in the form of relief, or the said emblem 74 can be placed to stand out in any other way, for example, by using a different color. In order to ensure that the slide tongue 22 is particularly easy to operate when it is being moved in relation to the wiper arm 12, in this case the members 54 of the slide tongue 22 have ribs 76.
    [00051] Fig. 8 shows the sliding tongue 22 to release the rocker 34, that is, the sliding tongue 22 moved forward in the mounting position or in the removal position (cf. Fig. 7) in a perspective view from below. The direction of travel forward is shown by an arrow 77. In the removal position, the spikes 48 are level in the regions 60.62, so they are no longer resting on the rails 56. The coupling nose 64 is located if engaged in the front hitch notch 66. The nose hitch 64 in the front hitch notch 66 as a result of the forward movement can be clearly heard and felt by the mechanic.
    [00052] Then, as shown in Fig. 9, the adapter 26 that supports the wiper blade 14 through the support 16 can be removed from the end region 40 of the wiper arm 12 in a downward, that is, perpendicular to the cleaning surface that can be defined by the cleaning movement of the windscreen wiper brush 14.
    [00053] The direction of assembly and the direction of removal are shown with a movement arrow 78 in Fig. 9. When assembling, adapter 26 and with it the wiper blade 14 that needs to be replaced , are correspondingly moved in a downward (downward) direction.
    [00054] Fig. 10 shows the wiper arm 12 that holds the wiper brush 14 in a side perspective, the wiper brush 14 being tilted in relation to the wiper arm 12, that is, as a result of the inclination of the support 16 in relation to the rocker arm 34 resting on the wiper arm 12. This side view shows that one of the members 44 of the wiper arm windscreen 12 has a notch 80 that allows an upward movement of the spoiler20 caused by tilting the wiper blade 14.
    [00055] Two stops 82 formed on each side of the support 16 and chamfered in relation to the respective external sides of the support 16 (cf. Fig. 5) limit the relative movement of the support 16 in relation to the rocker 34. The inclination of the brush windscreen wiper 14 in the opposite direction to the one shown in Fig. 10 causes the spoiler20 to move upwards (upwards) in its region facing the support 16. In this process, a recess in the form of the notch 84 on the front wall 70 of the sliding tab 22 ensures that the spoiler20 can move upwards (upwards) (cf. Fig. 11).
    [00056] Finally, Fig. 11 shows, as an example, how it is possible to avoid incorrect assembly, in this case, through the geometric arrangement of the projection 32 of the rocker 34 and the notch 52 corresponding to this projection 32 on the backrest 42 of the wiper arm 12. For example, for a wiper arm 12 on the passenger side and the wiper brush 14 associated with it, a specific projection design 32 can be provided corresponding to the place where the windscreen wiper arm 12 is attached and in the notch 52 corresponding to it.
    [00057] In the design of the wiper arm 12 and rocker arm 34 shown in Fig. 11, the notch 52 is not rectangular (as is the case, for example, in the design of the projection 32 and the notch 52 in Fig. 9 ), so the projection 32 is, instead, rectangular in its rear region and semicircular in its front region. Thus, the notch 52 corresponding to this partially semicircular projection 32 on the backrest 42 of the wiper arm 12 is also semicircular in the front and angled in the rear. In alternative variants, distinct designs of projection 32 and notch 52 can ensure protection against inadvertent changes.
    [00058] The connection arrangement shown here for connecting the wiper blade 14 to the wiper arm 12 is possible using the design of the wiper arm 12 in which it is formed under the in the form of a single rod arm, and using the windscreen wiper arms 12 with a more robust design, for example, a different shape in the region of the end region 40 and the rear region of the wiper arm 12 contiguous to the region of the end region 40 respectively.
