Description

description

Wiper device prior art

The invention relates to a wiper device according to the preamble of patent claim 1.

It is already a wiper device for a motor vehicle window, with a wiper arm adapter unit and a blade adapter unit, which form a positive connection in an assembled state known.

Disclosure of the invention

The invention relates to a wiper device for a motor vehicle window, with a Wscharmadaptereinheit and a blade adapter unit, which form a positive connection in an assembled state.

It is proposed that the scraper device has at least one movably mounted latching means, which is provided for restricting the scarf adapter unit in the mounted state in its freedom of movement at least substantially in a vertical direction of the scraper adapter unit, whereby the wiper device can be mounted particularly simply. In this context, a "wiper arm adapter unit" should be understood to mean, in particular, an adapter unit which has a contact area to a Wsch arm component and captively connected to the Wscharmbauteil and is intended to provide a coupling region of the Wscharmbauteils for coupling and / or contacting with the Wschblattadaptereinheit In this context, a "wiper blade adapter unit" is to be understood as meaning, in particular, an adapter unit which has a contact area to a contact area. Has wiper blade component and captively connected to the wiper blade component and is intended to provide a coupling region of the Wschblattbauteils for coupling and / or contacting with the Wscharmadaptereinheit. The wiper blade adapter unit preferably has a base body which provides a coupling surface for the coupling and / or contacting of the wiper arm adapter unit. In this context, a "mounted state" is to be understood as meaning, in particular, a state in which the blade adapter unit and the wscharmadaptor unit are coupled to one another In this context, a "latching means" should be understood to mean, in particular, a means which experiences an elastic deformation during an assembly procedure , In this context, "provided" should be understood to mean, in particular, specially equipped and / or designed, in this context a "vertical direction" being understood to mean, in particular, a direction which is perpendicular to a plane of the wash. In this context, a "wiping plane" is to be understood as meaning, in particular, an idealized plane which is wiped by an airfoil attached to the airfoil adapter unit in an operating state. "Substantially" should in this context be understood to mean, in particular, a deviation of less than 10 °.

In a further embodiment, it is proposed that the latching means is provided to be deflected during assembly at least substantially parallel to a transverse direction of a base body of the blade adapter unit, whereby the latching means can absorb particularly large forces. In this context, a "transverse direction" should be understood to mean, in particular, a direction which is perpendicular to a longitudinal direction and perpendicular to a vertical direction and runs parallel to a wiping plane extends at least substantially parallel to a main extension direction of the wiper blade adapter unit. In this context, a "vertical direction" should be understood to mean, in particular, a direction which is perpendicular to the plane of the wash.

It is further proposed that the latching means is provided to be deflected during assembly at least substantially parallel to a longitudinal direction of a base body of the blade adapter unit, whereby the Locking means can be operated very easily. In this context, a "longitudinal direction" should in particular be understood as meaning a direction which extends at least substantially parallel to a main extension direction of the wiper blade adapter unit.

If the latching means is formed integrally with a base body of the wiper blade adapter unit, the blade adapter unit and the latching means can be produced particularly favorably. The term "integral" should be understood in particular to be materially bonded, as for example by a welding process and / or adhesive process, etc., and particularly advantageously formed, such as by the production from a casting and / or by the production in a single- or multi-component injection molding process.

Furthermore, it is proposed that the locking means is designed as a Wederhaken, whereby a particularly fast assembly of the washing device can be provided.

If the latching means is arranged on a housing means of the sheet-metal adapter unit which forms at least a majority of a visible outer surface of the sheet-fed adapter unit in at least one operating state, the wiper device can be advantageously protected against external influences such as, for example, water. In this context, a "major part" should be understood as meaning, in particular, more than 50%, preferably 70%.

A particularly stable embodiment of the wiper device can be achieved if a main body of the Wschblattadaptereinheit has a fastening pin which forms a positive connection with a mounting recess of the Wscharmadaptereinheit in at least one operating condition.

If the latching means engages in a mounting recess of the wiper arm adapter unit in at least one operating state, the latching means can be arranged particularly easily accessible to an operator. drawings

FIG. 1a shows a wiper device for a motor vehicle window, with a wiper arm adapter unit 10a and a wiper blade adapter unit 12a in an opened state. Disposed on the wiper blade adapter unit 12a is a movably mounted locking means 14a, which is designed as a remover means 18a.

The remodeling means 18a is pivotally mounted on a pivot 20a on a main body 22a of the wiper blade adapter unit 12a. The main body 22a connects the wiper blade adapter unit 12a to a separately formed wiper blade 24a. However, it is also conceivable in this connection to form the wiper blade adapter unit 12a in one piece with the wiper blade 24a.

The swath adapter unit 10a is formed integrally with a wiper arm 26a. However, it is also conceivable in this connection to form the wiper arm adapter unit 10a separately from the wiper arm 26a and to connect them together via a suitable connecting element.

The wiper arm adapter unit 10a has two backstops 28a and one attachment nose 30a. The back stops 28a are flush with side walls 32a of the swadder adapter unit 10a. The fastening lug 30a is formed as an extension at one end of the Wscharmadaptereinheit 10a and has a mounting recess 34a.

The main body 22a of the wiper blade adapter unit 12a has two integrally connected counterstops 36a, which are arranged on side walls 38a of the main body 22a.

On two lateral inner surfaces 40a of the Umhausungsmittels 18a two integrally formed with the inner surfaces 40a projections are arranged as a movably mounted latching means 56a. The latching means 56a are designed as throwing hooks and can be moved from a starting position essentially parallel to a latching hook. ner transverse direction 54a of the body 22a deflect and move independently back to the starting position.

The wiper arm adapter unit 10a is lowered onto the base body 22a in a vertical direction 44a for mounting with the wiper blade adapter unit 12a. The back stops 28a terminate flush with the counterstops 36a and thus avoid longitudinal movement of the wiper arm adapter unit 10a relative to the wiper blade adapter unit 12a, which runs parallel to a longitudinal direction 16a (FIG. 1b).

As FIG. 1 b further shows, the wiper arm adapter unit 10a rests positively on the base body 22a. A movement of the wiper arm adapter unit 10a relative to the blade adapter unit 12a is now only possible parallel to the vertical direction 44a. In order to avoid this movement, the wrapping means 18a pivots through the pivot joint 20a about a pivot axis 46a, which is arranged substantially parallel to the transverse direction 54a, and positively encloses the wiper arm adapter unit 10a. During assembly, the latching means 56a are deflected substantially parallel to the transverse direction 54a of the wiper blade adapter unit 12a.

The locking means 56a engage under the counter-stops 36a and prevent pivoting of the Umhausungsmittels 18a back into the open state. Thus, the Wscharmadaptereinheit 10a is limited in their freedom of movement relative to the wiper blade adapter unit 12a in its vertical direction 44a and is in an assembled state (Figure 1 c). The remover 18a, in an assembled state, forms a majority of a visible outer surface of the wiper blade adapter unit 12a.

Fourteen further embodiments of the invention are shown in FIGS. The following descriptions are essentially limited to the differences between the exemplary embodiments, wherein reference can be made to the description of the first exemplary embodiment with regard to components, features and functions that remain the same. To distinguish the embodiments of the letter a in the reference numerals of the embodiment in Figure 1 is replaced by the letter b to o in the reference numerals of the embodiments of Figures 2 to 15. With regard to the same Components, in particular with regard to components with the same reference numerals, can in principle be made to the drawings and / or the description of the first embodiment.

FIG. 2 a shows a further exemplary embodiment of a wiper device with a wiper arm adapter unit 10 b and a wiper blade adapter unit 12 b in an opened state. The Wscharmadaptereinheit 10b has a arranged in a wiper arm 26b mounting recess 34b.

The blade adapter unit 12b has a base body 22b with a guide rail 66b and a locking means 14b. The locking means 14b is formed as a movably mounted locking means 56b, which is integrally connected to the base body 22b. The locking means 56b is formed as a barb. At one end of the guide rail 66b, a projection 50b is arranged.

FIG. 2b shows the wiper device in a second assembly step. One end of the Wscharmadaptereinheit 10b is inserted under the projection 50b. Rotation of the wiper arm adapter unit 10b about a transverse axis 64b brings the wiper device into an assembled state (FIG. 2c). In this case, the latching means 56b is first deflected by the Wscharmadaptereinheit 10b substantially parallel to a longitudinal direction 16b of the base body 22b of the wiper blade adapter unit 12b and then snaps into the mounting recess 34b.

In the assembled state, the Wscharmadaptereinheit 10b is limited in their freedom of movement in a transverse direction 54b. The locking means 56b limits the wiper arm adapter unit 10b in a longitudinal direction 16b and in a vertical direction 44b.

FIG. 3a shows a further exemplary embodiment of a washing device with a wiper arm adapter unit 10c and a blade adapter unit 12c in an opened state. The wiper arm adapter unit 10c has a fastening recess 34c arranged in a wiper arm 26c. The wiper blade adapter unit 12c has a base body 22c with a guide rail 66c and a locking means 14c. The locking means 14c is formed as integrally connected to the guide rail 66c, movably mounted locking means 56c, which has a barbed shape. At one end of the guide rail 66c, a protrusion 50c is disposed.

FIG. 3b shows the wiper device in a second assembly step. One end of the swath adapter unit 10c is inserted under the protrusion 50c. Rotation of the wiper arm adapter unit 10c about a transverse axis 64c brings the wiper device into an assembled state (FIG. 3c). In this case, the latching means 56c is initially deflected by the Wscharmadaptereinheit 10c substantially parallel to a transverse direction 54c and then snaps over the wiper arm 26c. The fastening recess 34c terminates flush with a fastening pin 60c, which is arranged on a bearing surface 48c of the base body 22c.

When mounted, the wiper arm adapter unit 10c is limited in its freedom of movement in the transverse direction 54c. The latching means 56c limits the wiper arm adapter unit 10c exclusively in a vertical direction 44c. A movement of the wiper arm adapter unit 10c in the longitudinal direction 16c is avoided by a positive locking of the fastening recess 34c with the fastening pin 60c.

FIG. 4a shows a further exemplary embodiment of a washing device with a wiper arm adapter unit 10d and a blade adapter unit 12d in an opened state. The Wscharmadaptereinheit 10d has a mounting recess 34d and a back stop 28d.

The blade adapter unit 12d has a locking means 14d, which is pivotably mounted about a pivot axis 46d and is formed by a redistribution means 18d. The pivot axis 46d is arranged substantially parallel to a transverse direction 54d.

The blade adapter unit 12d further comprises a main body 22d with a fixing pin 60d having a substantially square cross section having. On the main body 22d, a counter-abutment 36d is arranged on a side wall 38d.

FIG. 4b shows the wiper device in a second assembly step. The wiper arm adapter unit 10d rests on the base body 22d of the wiper blade adapter unit 12d. The fastening recess 34d forms a positive connection with the fastening pin 60d and thus avoids a movement of the wiper arm adapter unit 10d relative to the wiper blade adapter unit 12d parallel to a longitudinal direction 16d and parallel to the transverse direction 54d. In addition, the freedom of movement in the longitudinal direction 16d is avoided by a positive connection of the counterstop 36d with the backstop 28d.

In order to avoid a movement of the wiper arm adapter unit 10d in a vertical direction 44d of the main body 22d, the locking means 14d is pivoted about the pivot axis 46d. In this case, a part of the Umhausungsmittels 18d engages over the wiper blade adapter unit 12d and limits this in their freedom of movement in the vertical direction 44d.

FIG. 4c shows the washing device in an assembled state. A pivoting back of the Umhausungsmittels 18 d in the open state is prevented by a movably mounted locking means 56 d, which is arranged in a recess of the Umhausungsmittels 18 d. The latching means 56d is designed as a heat hammer and locks with the base body 22d in a manner familiar to the person skilled in the art.

FIG. 5a shows a further exemplary embodiment of the wiper device from FIGS. 12a-c with a remodeling means 18e which is arranged pivotably mounted on the wiper blade adapter unit 12e. Arranged on the housing means 18e is a securing means 42e, which is designed as a latching means 56e and has the shape of a throwing hook.

FIG. 5b shows the washing device in a second assembly step. The remodeling means 18e forms a lateral guide for the wiper arm adapter unit FIG. 5c shows the wiper device in an assembled state. The wrapping means 18e is pivoted onto the wiper arm adapter unit 10e and forms a positive connection with it. The securing means 42e engages in a recess 58e of the main body 22e of the wiper blade adapter unit 12e. The recess 58e is arranged in the fastening pin 60e of the main body 22e. A pivoting back of the Umhausungsmittels 18 e in the open state is thus avoided.

FIG. 6a shows a further embodiment of a washing device with a wiper arm adapter unit 10f and a wiper blade adapter unit 12f in an opened state. The swath adapter unit 10f has a fastening recess 34f.

The sheet adapter unit 12f has a locking means 14f, which is freely movably supported, and is formed by a housing remover 18f.

The blade adapter unit 12f further includes a base body 22f having a fixing pin 60f that includes a substantially square cross section.

The fastening recess 34f forms a positive connection with the fastening pin 60f and thus avoids a movement of the wiper arm adapter unit 10f in a longitudinal direction 16f and a transverse direction 54f. A movement of the wiper arm adapter unit 10f is possible only in a vertical direction 44f.

FIG. 6b shows the wiper device in an assembled state. The remodeling means 18f is pushed over the Wscharmadaptereinheit 10f, and it engages in two arranged in the main body 22f sinkings 52f a. A pushing back of the Umhausungsmittels 18f is avoided by a locking means 56f, which is arranged on the base body 22f. The latching means 56f is formed as a barb and engages in a recess of the Umhausungsmittels 18f.

FIG. 7a shows a further exemplary embodiment of a washing device with a wiper arm adapter unit 10g and a wiper blade adapter unit 12g in an opened state. The Wscharmadaptereinheit 10g has a mounting recess 34g and a back stop 28g. The wiper blade adapter unit 12g has a main body 22g with a locking means 14g. The locking means 14g is formed as integrally connected to the base body 22g, movably mounted locking means 56g and has a barb form. The main body 22g has a counter stop 36g. In an assembly process, the latching means 56g is deflected substantially parallel to a longitudinal direction 16g of the main body 22g of the wiper blade adapter unit 12g.

FIG. 7b shows the wiper device in an assembled state. The wiper arm adapter unit 10g forms a positive connection with the main body 22g. A movement of the Wscharmadaptereinheit 10g in a transverse direction 54g is thereby avoided. The counter-abutment 36g of the main body 22g is flush with the back stopper 28g of the wiper arm adapter unit 10g, thereby preventing movement of the swash-arm adapter unit 10g in the longitudinal direction 16g.

The locking means 56g engages in the fastening recess 34g of the wiper arm adapter unit 10g. Thereby, a freedom of movement of the Wscharmadaptereinheit 10g is limited in a vertical direction 44g.

FIG. 8a shows a further embodiment of a wiper device with a wiper arm adapter unit 10h and a wiper blade adapter unit 12h in an opened state. The Wscharmadaptereinheit 10h has a mounting recess 34h and a back stop 28h.

The blade adapter unit 12h has a main body 22h, with a counter stop 36h and a movably mounted latching means 56h, which is designed as a barb. The main body 22h has an arcuate guide rail 66h, which allows a recording of the wiper arm adapter unit 10h in a rotational movement.

FIG. 8b shows the washing device in a second assembly step. Side walls 32h of the wscharmadaptereinheit 10h partially surround the main body 22h of the blade adapter unit 12h and thus avoid movement of the wiper arm adapter unit 10h relative to the blade adapter unit 12h in a transverse direction 54h. The Wscharmadaptereinheit 10h is relative to the main body 22h of the wiper blade adapter unit 12h is rotated about a transverse axis 64h, which is arranged substantially parallel to the transverse direction 54h.

Figure 8c shows the wiper device in an assembled state. In a front region 62h, the wiper arm adapter unit 10h with the wiper blade adapter unit 12h forms a form fit which avoids a movement of the wiper arm adapter unit 10h relative to the scanner blade adapter unit 12h in a vertical direction 44h. The latching means 56h limits movement of the Wscharmadapter- unit 10h relative to the blade adapter unit 12h substantially in the vertical direction 44h and thus avoids pivoting back of the Wscharmadapter- unit 10h in the open state.

FIG. 9a shows a further exemplary embodiment of a washing device with a wiper arm adapter unit 10i and a wiper blade adapter unit 12i in an opened state. The wscharmadaptereinheit 10i has a Befestigungsaus- recess 34i and a back stop 28i.

The blade adapter unit 12i has a main body 22i with a locking means 14i. The locking means 14i is formed as integrally connected to the base body 22i, movably mounted locking means 56i. The main body 22i also has a counter-stop 36i.

FIG. 9b shows the wiper device in a second assembly step. In a front region 62i, the wiper arm adapter unit 10i abuts the blade adapter unit 12i. A rotational movement of the Wscharmadaptereinheit 10i about a transverse axis 64i, which extends substantially parallel to a transverse direction 54i of the base body 22i, deflects the locking means 56i in a longitudinal direction 16i.

FIG. 9c shows the washing device in an assembled state. The wiper arm adapter unit 10i forms a positive connection with the base body 22i. A movement of the Wscharmadaptereinheit 10i in a transverse direction 54i is thereby avoided. The counter-abutment 36i of the main body 22i terminates flush with the backstop 28i of the swadder adapter unit 10i and thereby prevents movement of the swash-arm adapter unit 10i relative to the wiper-blade adapter unit 12i in the longitudinal direction 16i. The locking means 56i is designed as a barb and engages in the fastening recess 34i of the Wscharmadaptereinheit 10i. Thereby, a freedom of movement of the wiper arm adapter unit 10i is restricted in a vertical direction 44i.

FIG. 10a shows a further exemplary embodiment of a washing device with a wiper arm adapter unit 10j and a blade adapter unit 12j in an opened state. The Wscharmadaptereinheit 10j substantially corresponds to the Wscharmadaptereinheit 10a of the first embodiment.

The blade adapter unit 12j has a base body 22j with a counter-stop 36j extending in a vertical direction 44j and a movably mounted locking means 56j. The wiper arm adapter unit 10j is placed in a linear movement, which runs parallel to the vertical direction 44j, on the base body 22j of the blade adapter unit 12j.

FIG. 10b shows the washing device in an assembled state. The counter-abutment 36j of the main body 22j terminates flush with a back stop 28j of the Wscharmadaptereinheit 10j. The locking means 56j is formed as a barb and engages in a mounting recess 34j of the Wscharmadaptereinheit 10j, and thus prevents movement of the Wscharmadaptereinheit 10j relative to the Wschblattadaptereinheit 12j in the vertical direction 44j.
