CONNECTION ASSEMBLY FOR CONNECTING A WIPER BLADE TO A WIPING ARM FOR ONE

DISC WASHER OF A VEHICLE

The invention relates to a connection arrangement for connecting a wiper blade to a wiper arm for a windshield wiper system of a vehicle. The

Connecting arrangement comprises a trained for holding the wiper blade

Connecting element which can be mounted on the wiper arm in a mounting direction, which extends transversely to a wiping surface which can be defined by the wiping movement of the wiper blade. At least one securing element of the connecting arrangement serves for the positionally secured holding of the connecting element on the wiper arm. Furthermore, the invention relates to a method for connecting a wiper blade to a wiper arm of a windshield wiper system of a vehicle.

DE 691 01 340 T2 describes a joint connection between a wiper arm and a wiper blade. In the wiper arm, which has a U-profile in cross-section, an opening for receiving a bolt is provided, which is displaceable along the wiper arm. When the bolt is pushed away from the free end of the wiper arm, that is to say towards the rear, a receptacle provided on the bolt releases a hinge axle which connects two longitudinal walls of a chuck together. The chuck is in this case inserted into an opening which is formed in a main bracket of the wiper blade, wherein clamps formed on the chuck engage in recesses provided on the main bracket.

DE 101 30 903 A1 describes a wiper arm of a windshield wiper system for a vehicle whose end region has a U-profile in cross-section, which is open at the bottom. An adapter, which holds a wiper blade, can be introduced from below into the end region of the wiper arm, that is to say in a mounting direction which runs perpendicular to a wiping surface that can be defined by the wiping movement of the wiper blade. In sidewalls of the adapter recesses are provided, the internal dimensions of the outer dimensions of Projections correspond, which protrude laterally and inwardly from legs of the wiper arm. When inserting the adapter into the end region of the wiper arm in the mounting direction so the projections move along the recesses. To lock the adapter relative to the wiper arm, the adapter is displaced together with the wiper blade toward an open end of the wiper arm, and the projections on the wiper arm reach into detent niches which are provided on the adapter. A latching tongue arranged on the adapter is introduced in this position-secured position of the adapter into a recess arranged on the wiper arm and thus indicates that the adapter has reached its operating position.

DE 10 2008 011 449 A1 likewise describes a connection of a wiper blade to a wiper arm by means of a wiper blade-side adapter, which is introduced from below into an end region of the wiper arm. Subsequently, the adapter is moved laterally together with the wiper blade to one end of the wiper arm in order to achieve locking of the adapter relative to the wiper arm and thus the assumption of a functional position of the adapter.

A disadvantage of such connection arrangements is the fact that the securing of the adapter in its position with respect to the wiper arm requires a cumbersome handling of the adapter.

DE 10 2005 016 485 A1 describes a device for the articulated connection of a wiper blade to a wiper arm of a windshield wiper system. An end area of the

Wischarms is designed as a downwardly open, cuboid hollow body, protruding from the side walls of two projections inwardly. An adapter for holding a wiper blade has two locking tongues, which lock when inserting the adapter in the wischarmseitigen hollow body from below with the two projections. Another, formed on a side wall of the hollow body and inwardly projecting projection engages in a recess which is provided in the adapter. In this way, the adapter is secured in position held on the end portion of the wiper arm.

Such a connection arrangement is comparatively complicated, and moreover it is difficult to disassemble the adapter and with it the wiper blade of the wiper arm.

The object of the present invention is therefore to provide a connection arrangement of the aforementioned type and a corresponding method, which or which allows a particularly simple and reliable connection of a wiper blade with a wiper arm of a windshield wiper system.

This object is achieved by a connection arrangement with the features of

Patent claim 1 solved. Advantageous embodiments with appropriate

Further developments of the invention are specified in the dependent claims.

The connection arrangement according to the invention for connecting a wiper blade to a wiper arm of a windshield wiper system of a vehicle comprises a connection element designed to hold the wiper blade. The connection element is mounted on the wiper arm in a mounting direction, which transverse to a through the

Wiping movement of the wiper blade definable wiping surface runs. One

Securing element of the connection arrangement, which serves for the positionally secured holding of the connection element on the wiper arm, is configured as a slide arranged on the wiper arm and having a U-profile in cross section, which slides along the wiper arm from an assembly position into a connection element securing the connection element

Function position is displaced. A particularly simple and reliable connection of the wiper blade to the wiper arm is in this case achieved that does not need to be moved together with the wiper blade from the mounting position into the functional position to set the wiper blade on the wiper arm, the connection element. Rather, the attachment element remains in its mounting position, while only the slider is moved along the wiper arm to the

Secure connection element against loosening of the wiper arm. This greatly facilitates handling of the wiper blade when mounted to or disassembled from the wiper arm.

In this case, the slide on a back and two legs, wherein at least one of the legs of the wiper arm engaging around the side of the projection is arranged on the legs of the slider. Such a slider provides an impact protection when the wiper arm hits the disc without a wiper blade mounted thereon, for example due to carelessness of an operator after dismantling the wiper blade from the wiper arm. Such impact protection is particularly effective especially when the wiper arm is formed of a metal and the slide of a

more yielding material, such as plastic. In addition, a particularly good guidance of the slide along the wiper arm is ensured by the slider, which engages around the wiper arm on the underside. The installation of a wiper blade having the connecting element to the wiper arm is carried out by an operator in a particularly simple and intuitive manner, whereby a particularly high level of security against incorrect assembly is achieved. In order to disassemble the wiper blade, the slider only needs to be moved out of the functional position securing the connection element into the mounting position, and then the connection element and with it the wiper blade can be pulled off the wiper arm against the mounting direction.

Since a wiper blade acts on the wiper arm on the wiper blade on the windshield of the vehicle, which presses the wiper blade against the windscreen, the wiper arm can then move the wiper blade securely over the windshield even if the slider is not in the functional position but in the operating position Assembly position is located. This also applies if the slider is defective, so that even in the functional position the

Connection element does not secure as desired.

The connection arrangement described here can also be realized with a comparatively small connection element. This is advantageous in that in a small space requirement entailing connecting element even with precipitation or when applying the washer with washing liquid only a small amount of water from the connection element takes place on the window of the vehicle.

In an advantageous embodiment of the invention, the slider for moving from the functional position to the mounting position from a front end portion of the wiper arm to the opposite end portion of the wiper arm to be displaced. To the

Spend the slider from the functional position in the mounting position so this is pushed backwards. This allows an operator to easily identify whether the slider is in the mounting position or in the functional position securing the connection element.

It is furthermore advantageous if the wiper arm has at least one latching notch which, in the functional position and / or in the assembly position of the slide, engages with a latching lug arranged on the slide. The engagement of the detent in the notch is in fact both visually perceptible and audible and noticeable. In this way, the operator can be sent a feedback that the slider is in the functional position or in the mounting position.

It is particularly favorable if one and the same latching nose engages in the functional position with a first latching notch and in the assembly position with a second latching notch is. Alternatively, however, only one notch can be provided, which is assigned to one of the two positions. Also, the wiper arm, the locking lug and the slider having the notches.

It has proven to be advantageous if the detent has a web which engages behind a leg of the wiper arm. Thus, a particularly secure attachment of the slider is achieved on the wiper arm.

In a further advantageous embodiment of the invention, the wiper arm at least in the region of the connecting element in cross-section on a U-profile, wherein on a back of the wiper arm a randliche recess is arranged, in which in the mounting position, a corresponding projection of the connection element

is included. If the projection, the outer dimensions of which correspond to the internal dimensions of the peripheral recess, is received in the peripheral recess, then it is ensured that the connection element and with it the wiper blade neither in the direction of the longitudinal extension of the wiper arm nor transversely thereto

Can move longitudinal extension direction. In other words, that's it

Connecting element and secured with this the wiper blade in the plane of the wiping surface by such a fit of the projection and the corresponding with this peripheral recess in position and fixed. In addition, it can be recognized by the operator at the point of entry of the projection into the peripheral recess that the attachment element is in the correct assembly position, in which a

Moving the slider is possible in the functional element securing the connection element.

If the projection and the marginal recess one of the round shape

have deviating contour, for example by the projection and the peripheral recess are oval or angular, in particular rectangular or square, so it can be realized by the introduction of the projection in the peripheral recess also a rotation of the connecting element relative to the wiper arm.

Preferably, at least a portion of the projection has a contour which is equal to a contour of a recess provided on the slider, wherein at least the portion of the projection in the functional position of the slider with the recess in abutment. In this way, can be optically controlled by bringing the slider with the portion of the projection, whether the slide the

Function has reached. As long as namely between the recess on the Slider limiting contour and the contour of the portion of the projection is still a distance, this is not the case.

In a further advantageous embodiment of the invention, the connection element has at least one further projection, which engages in the mounting position in a arranged in a back of the wiper arm passage opening. This ensures a particularly good fixation of the wiper blade relative to the wiper arm.

As a further advantage, it has been shown that the peripheral recess and the corresponding projection and / or the passage opening and the corresponding thereto further projection for a respective mounting location of the wiper arm on the vehicle are specifically designed. Thus, the geometry of the recess and / or the passage opening and the respectively associated projection for a driver-side wiper arm and the associated wiper blade can deviate from the geometry for a passenger-side wiper arm and the associated wiper blade. Also may be for a wiper arm for a vehicle with on the right or left side

arranged steering wheel each have a specific geometry of the recess and / or the passage opening and the respective corresponding projection are provided to ensure that only the actually associated wiper blade can be mounted on the wiper arm provided therefor. Such an exchange protection can also be provided in order to distinguish the wiper arm and the wiper blade of a rear window wiper from a wiper arm and the wiper blade of a windshield wiper.

Additionally or alternatively, at least one pin insertable into a corresponding depression in the attachment element may be arranged on the legs of the slider. When the pin is inserted into the recess in the connecting element, a particularly good stiffening of the connecting element in the functional position of the slider can be achieved. In addition, such a good connection of the connection element with the slide is given.

It is furthermore advantageous if an end wall is formed by the attachment element, by means of which in the assembly position an open end region of the wiper arm can be closed at least in regions. Thus, a visually appealing conclusion of the end portion of the wiper arm is provided by the connection element. In order to achieve a particularly secure fixation of the connecting element on the wiper arm in the ontagestellung, it may be provided according to a further advantageous embodiment of the invention that the wiper arm at least one in the

Mounting direction has open recess, which is formed for receiving a formed on the connecting element corresponding projection.

As a further advantage, it has been shown, when the connecting element comprises a lower part holding the wiper blade and an upper part fixed in the functional position on the wiper arm, the lower part being held movably relative to the upper part. As a result, the wiper blade can adapt to the course of the writing surface during wiping of the generally spherically curved disk. The fact that the wear-prone parts, which the relative movement between the wiper arm and

Wiper blade allow parts of the connection element, they are also replaced when replacing the wiper blade together with the connection element. This ensures that the relative movement between the wiper blade and the wiper arm remains smooth.

Preferably, at least one stop formed on the lower part provides for limiting the relative movement of the upper part relative to the lower part. By attacks, namely, the relative movement of the wiper blade relative to the wiper arm can be particularly easily limited to the necessary, small amount.

If the wiper arm according to a further advantageous embodiment of the invention in the functional position with side walls of the upper part in abutment, this also ensures a particularly safe, in particular torsion, fixing the

Connecting element on the wiper arm.

The upper part may in particular be designed as a rocker, which is rotatably mounted on a guided through a through hole in the lower part pin or bearing pin. Such a bearing of the upper part of the lower part ensures a particularly good smoothness in the relative movement between the wiper arm and wiper blade.

Finally, it has proven to be advantageous if the slider and / or the wiper arm have a recess which is formed during a movement of the wiper blade relative to the wiper arm for receiving a component of the wiper blade. Thus, the slide and the wiper arm can be particularly largely closed in optical and acoustically advantageous manner, and yet is characterized by the Recesses allows the relative movement of the wiper blade relative to the wiper arm.

In the method according to the invention for connecting a wiper blade to a wiper arm of a windshield wiper system of a vehicle, a device for holding the wiper blade is provided

Wischblatts formed connecting element to the wiper arm mounted in a mounting direction, which extends transversely to a wiping surface defined by the wiping movement of the wiper blade. By means of at least one securing element is the

Attachment held on the wiper arm in a secured position. This is called as

Secured element arranged on the wiper arm and in cross-section a U-profile exhibiting slide along the wiper arm from an assembly position into a connecting element locking functional position.

The advantages and preferred embodiments described for the connection arrangement according to the invention also apply to the method according to the invention.

The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

Wiper blade; and an alternative embodiment of a wiper arm with arranged on this wiper blade, which is held by a wiper arm specific adapter.

From a windshield wiper system 10 of a vehicle, a wiper arm 12 and a wiper blade 14 are shown in detail in FIG. From an adapter 26 (see Fig. 2), which is received in an end region formed as a receiving area of the wiper arm 12, a lower part designed as a rider 16 is shown in Fig. 1, which

Spring rails 18 of the wiper blade 14 surrounds and thus holds the wiper blade 14. The wiper blade 14 further comprises a spoiler 20 and a wiper blade 21 (see Fig. 10) (not shown in Fig. 1) for wiping a disc (not shown in Fig. 1) of the vehicle. Furthermore, in Fig. 1, an end wall 70 of a rocker 34 of the To see adapter 26, which closes the forwardly open end of the wiper arm 12.

In order to hold the adapter 26 (see Fig. 2) securely on the wiper arm 12, a sliding bar 22 is arranged on the wiper arm 12, which in a longitudinal direction of the extension

Wiper arm 12 is slidably held on this. An arrow symbol 24 in the form of a double arrow applied to the sliding bar 22 indicates the directions in which the sliding bar 22 can be displaced relative to the wiper arm 12.

In a functional position of the sliding bar 22 shown in FIG. 1, this ensures that the adapter 26 (see FIG. 2) and with it the wiper blade 14 does not depend on the

Wiper arm 12 can be deducted. In this functional position of the

Sliding latch 22 is provided on the sliding latch 22, a semicircular contour having recess 28 in abutment with an upper cylindrical portion 30 of a likewise cylindrical projection 32, which upwards over a

Base body of the rocker 34 of the adapter 26 protrudes (see Fig. 2 and Fig. 5).

2 shows the rocker 34, which is formed as the upper part of the multi-part adapter 26, without the rocker 34 concealing sliding bolt 22. The rocker 34 is rotatably mounted on a pin-shaped bearing pin 36, which by a provided in the tab 16 through opening 38 (FIGS. see Fig. 5) is passed. In the

Through holes 38 may be provided to fix the bearing pin 36 rotatably in this (see Fig .. 5).

When the wiper blade 14 is to be received on the wiper arm 12 in its end region 40 by means of the adapter 26 holding it, it is introduced from below into the downwardly open end region 40 of the wiper arm 12 (see Fig. 9). For this purpose, first, the slide bolt 22 is displaced into a shown in Fig. 7, the mounting of the adapter 26 enabling mounting position, which is also a disassembly of the adapter 26 enabling disassembly position.

As is apparent from Fig. 3, the end portion 40 of the wiper arm 12 in cross-section on a U-profile, which comprises a back 42 and two of the back 42 downwardly extending leg 44. The legs 44 each have two recesses 46 which are open at the bottom and which, when the adapter 26 is inserted into the end region 40, receive two locking lugs 48 which protrude beyond respective side walls 50 of the rocker 34 (see FIG. When the four locking lugs 48 are received in the four corresponding with these recesses 46 in the two legs 44 of the end portion 40 of the wiper arm 12, the adapter 26 can no longer move in the direction of the longitudinal extent of the wiper arm 12. In addition, then the projection 32 of the rocker 34 in abutment with a randlicher recess 52, which is formed in the back 42 of the wiper arm 12. A further recess 86 in the back 42 of the wiper arm 12 serves to receive a raised portion 88 of the rider 16, which has this in the region of the passage opening 38 (see Fig. 2, Fig. 3 and Fig. 5).

In addition, the back 42 of the wiper arm 12 in the end region 40 a

Through opening 53, in which a projection 55 of the rocker 34 engages when inserting the adapter 26 in the end portion 40 (see Fig. 2 and Fig. 3). This serves as release protection or for further fixing of the adapter 26 on the wiper arm 12.

When the adapter 26 is inserted into the end portion 40 of the wiper arm 12, the side walls 50 of the rocker 34 with the inner sides of the legs 44 in abutment. As a result, fixation of the adapter 26 on the wiper arm 12 is ensured even in a direction transverse to the direction of extent of the wiper arm 12, that is to say transversely to the longitudinal extension direction of the wiper blade 14.

Furthermore, the sliding bar 22 ensures that the adapter 26 can not move out of the end region 40 of the wiper arm 12 in the vertical direction, ie perpendicular to the wiping surface that can be defined by the wiping movement of the wiper blade 14.

For this purpose, as shown particularly in FIG. 4, on respective side walls 54 of the

Cross section also having a U-profile sliding latch 22 two strips 56 which project from an inner side of the respective side wall 54 inwardly. These strips 56 surround the wiper arm 12 in the end region 40 on the underside and thus serve in cooperation with a back 58 connecting the side walls 54 of the sliding latch 22 (see FIG. 3) as a guide during the translatory displacement of the sliding latch 22 relative to the wiper arm 12.

In addition, the recorded in the recesses 46 of the wiper arm 12 rest

Bolt warts 48 on the strips 56 of the sliding bolt 22 when it is shifted to its in Fig. 1 functional position, that is in the present case forward. A region 60 in front of the front strip 56 and a region 62 between the two strips 56 make it possible to move in the assembly position, ie to the rear

Slide bar 22 to introduce the locking lugs 48 of the rocker 34 in the provided in the legs 44 of the wiper arm 12 recesses 46 by the adapter 26 is inserted from below into the end portion 40 of the wiper arm 12 (see Fig .. 9).

Latching projections 64 protruding inwardly from the side walls 54 of the sliding latch 22 can be introduced into front notches 66 or into rear notches 68 formed in the two legs 44 of the wiper arm 12 in its end region 40. If the respective latching lug 64 is located in the front latching notch 66, then the sliding latch 22 is in contact with the front end wall 70 of the rocker 34 (compare FIGS. 1, 6 and 10). At the same time, two tooth-like pins 71, which project forward beyond the side walls 54 of the sliding latch 22, engage in recesses which are provided in the end wall 70 of the rocker 34.

If, on the other hand, the sliding latch 22 is pushed backwards, that is to say if the latching lug 64 is located in the rear latching notch 68, then the front end wall 70 is spaced from the sliding latch 22 (compare FIGS. 7 and 8). The engagement of the detent 64 in the front notch 66 or in the rear notch 68 is clearly audible and tactile by an operator who operates the sliding latch 22, so haptically detected.

Of the latching lugs 64 of the sliding latch 22, respective webs 73 project upwards, which engage behind the legs 44 of the wiper arm 12 in the end region 40 when the sliding latch 22 is mounted on the wiper arm 12 (compare FIGS. 4, 6 and FIG. 8th).

Further, optical feedback on the achievement of the mounting or dismounting of the adapter 26 from the end portion 40 of the wiper arm 12 enabling mounting position of the sliding latch 22 is given by the position of the portion 30 relative to the sliding latch 22. The portion 30, which over the randliche

Recess 52 protruding in the back 42 of the wiper arm 12 is spaced from the recess 28 provided in the sliding latch 22 when the detent 64 is located in the rear notch 68 (see Fig. 7 and Fig. 8).

If, however, the sliding latch 22 is pushed forward, the latching lug 64 is located in the front latching notch 66. In this case, the rear latching notch 68 is exposed (see FIG. 6), and there is no space between the portion 30 of the projection 32 and the recess 28 in the spine 58 of the sliding bar 22 (see Fig. 1).

Fig. 6 shows the displaced in its operative position forward slide bolt 22 which holds the rocker 34 by the disposed on the side walls 50 of the rocker 34 locking lugs 48 on the laterally inwardly projecting strips 56 of

Slide latch 22 rest. In the functional position, the latching lug 64 formed on the sliding latch 22 engages with the front latching notch 66, which is located in the leg 44 of the wiper arm 12. The rear notch 68, however, is free.

In contrast, in the assembly position shown in Fig. 7 or disassembly position of the sliding bolt 22, this pushed backwards, and the front notch 66 is exposed, while the locking lug 64 is inserted into the rear notch 68. The cylindrical portion 30 of the projection 32 of the rocker 34 is spaced from the semicircular recess 28 in the back 58 of the sliding latch 22.

The cylindrical portion 30 may, as shown here by way of example, have a relief-like protruding emblem 74, such as a brand emblem, for better recognition, or such an emblem 74 may be highlighted in another way at this point, such as by color deposition. To be a particularly good

Handling of the sliding latch 22 when moving relative to the wiper arm 12 to ensure the side walls 54 or legs of the sliding latch 22 in the present case a corrugation 76.

Fig. 8 shows the rocker 34 releasing sliding bolt 22, so in the

Mounting position or disassembly position shifted backwards slide bolt 22 (see Fig. 7) in a perspective view from below. The direction of displacement to the rear is illustrated by an arrow 77. In the disassembly position, the bolt warts 48 are at the height of the areas 60, 62, so they no longer rest on the strips 56. The detent 64 is engaged in the rear notch 68. The engagement of the detent 64 in the rear notch 68 due to the displacement of the sliding latch 22 to the rear is clearly audible and noticeable to the operator.

Subsequently, as shown in Fig. 9, the adapter 26, which holds the wiper blade 14 by means of the rider 16 downwards, ie perpendicular to the wiping movement of the

Wiper blade 14 definable wiping surface are pulled out of the end portion 40 of the wiper arm 12. The mounting direction and the dismounting direction are shown in Fig. 9 by a

Motion arrow 78 illustrates. When mounting the adapter 26 and with this the wiper blade 14 is moved upward when disassembling a

to be exchanged wiper blade 14 down accordingly.

Fig. 10 shows the wiper blade 14 holding the wiper arm 12 in a side view, wherein the wiper blade 14 is tilted relative to the wiper arm 12, in consequence of

Tilting of the rider 16 relative to the voltage applied to the wiper arm 12 rocker 34. From this side view shows that one of the legs 44 of the wiper arm 12 has a recess 80, which is one with the tilting of the wiper blade 14th

accompanying movement of the spoiler 20 allows upward.

Two stops 82 (see Fig. 5) formed on each side of the rider 16 and bevelled towards respective outer sides of the rider 16 provide for limiting relative movement of the rider 16 relative to the rocker 34. Tilting the wiper blade 14 into that shown in Figs The direction opposite to that shown in FIG. 10 causes the spoiler 20 to move upwardly in its portion located in front of the rider 16. Here, a recess arranged in the end wall 70 of the rocker 34 in the form of a notch 84 ensures that the movement of the spoiler 20 is made possible upwards (compare FIG.

Finally, FIG. 11 shows by way of example how incorrect mounting is prevented in the back 42 of the wiper arm 12 by the geometric configuration of the projection 32 of the rocker 34 and the recess 52 corresponding to this projection 32. Thus, for a passenger-side wiper arm 12 and the associated wiper blade 14, a specific, corresponding to the mounting location of the wiper arm 12

Formation of the projection 32 and be provided with this corresponding recess 52.

In the embodiment of the wiper arm 12 and the rocker 34 shown in Fig. 11, the recess 52 in the back 42 of the wiper arm 12 is rectangular - and not in the rear area, as in the configuration of the projection 32 and recess 52 shown in Fig. 9 semicircular. Accordingly, with this of FIG. 11 rectangular recess 52 corresponding projection 32 in its rear, with the

Recess 52 to be brought into abutment area also rectangular. In alternative embodiments, divergent shapes of protrusion 32 and recess 52 may provide for swapping protection. The in the field of Front wall 70 of the rocker 34 provided projection 32 is clearly visible when pushed back sliding latch 22, as well as the shape of the recess 52 in the back 42 of the wiper arm 12th

Another element, which in the present case serves to ensure an exchange protection, is the projection 55 covered in the rear, by the sliding bar 22 in its mounting position and in its functional position, which after insertion of the adapter 26 up into the end region 40 of the wiper arm 12 in the Passage opening 53 in the back 42 of the wiper arm 12 engages. This projection 55 has a with the

Through opening 53 corresponding shaping and is in the embodiment of the connection arrangement shown in Fig. 9 around, while it is triangular in the embodiment shown in FIG. Again, in alternative

Embodiments alternative geometries of projection 55 and corresponding passage opening 53 may be provided.

The connection arrangement shown here for connecting the wiper blade 14 to the wiper arm 12 is possible both in embodiments of the wiper arm 12, in which this is designed as a simple rod arm, as well as wiper arms 12, in which this has a sophisticated design, such as a different each
