Title of the invention: Vehicle wiping device with a wiping arm provided with a wiping lip FIELD OF THE INVENTION

[0001] The present invention relates to a wiping device for a motor vehicle and in particular the field of passenger vehicles and utility vehicles. STATE OF THE ART

[0002] According to document DE 198 54 307 A1, a windscreen wiper blade for cleaning vehicle windows is known. The known wiper blade comprises a wiping blade carried by a bracket system.

[0003] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0004] The present invention aims to overcome the drawbacks of known devices and for this purpose relates to a wiping device for a motor vehicle comprising a wiping arm and a wiping lip, device characterized in that one end of the wiper arm is in the form of an open receiving profile in which the wiping lip slides along the longitudinal extension and, the wiping arm has at least one fixing installation for fixing the wiping lip in the open receiving profile and, at least one button for operating the fixing installation is provided on the wiping arm.

[0005] The wiping device according to the invention has the advantage of allowing better production and better operation with a simpler construction of the wiping device and thus simpler replacement of the wiping lip.

[0006] Advantageously, the wiping lip has a recess and the fastening device has a fastening element connected to the actuating button and which, in the installed state, engages in the recess of the wiping lip. The operating button can be pushed and thus hooked to engage, for example, in a fastening element made in the form of a relief of the actuating button and come into the recess of the wiping lip to be fixed there. The wiping lip is thus held for its movement in the longitudinal extension direction of the wiping arm.

[0007] Advantageously, the receiving profile has a fixing slot, the wiping lip has a spacer and a holding blade connected to the spacer and this spacer of the lip in the engaged state passes into the fixing slot so that the holding blade engages, inside, in the receiving profile of the wiping arm. This produces a reliable connection which maintains the position of the wiping lip during operation, when the wiping lip passes over the window.

[0008] Advantageously, the wiping arm is substantially closed at the end up to the receiving profile and an open section of the receiving profile is formed at least mainly as a function of a wiping lip retaining blade and a wiping lip spacer. This prevents the ingress of liquid or solid matter. This also ensures reliable operation.

[0009] Advantageously, an operating button is provided at least in the vicinity of the end of the wiper arm, which secures the wiper lip, in particular at its outer end, for the largest wiping arc. This facilitates engagement of the wiper lip. In addition, actuation by use, relative to the mounting position of the wiper arm on the vehicle, is facilitated, with, for example, a fixing eyelet close to the middle of the vehicle.

[0010] Advantageously, an operating button is provided at least near the inner end of the wiper arm, which facilitates operation by the user with respect to the mounting position of the wiper arm on the vehicle, for which, for example, there is a fixing eyelet near one side of the vehicle.

[0011] Advantageously, the operating button is at the outer end of the wiper arm, which allows the wiper lip to be simply removed without, for example, being hindered in fixing an output shaft of the electric motor. Advantageously, the inner end of the wiper arm has a fixing eyelet for the wiper arm, which allows for advantageous driving of the wiper arm.

[0012] According to another advantageous characteristic, the wiping arm is at least practically in one piece, which allows a robust and simple production.

[0013] Advantageously, the wiper arm is in several parts and the actuating button is provided on a part of the wiper arm. Thus, according to a possible embodiment, if necessary, the part can be replaced for repair.

[0014] Advantageously, the wiper arm has a fixing body on which a fixing eyelet is made. This makes it possible to connect the output shaft of the electric motor to a shaft or similar means actuated by a linkage.

[0015] Advantageously, the wiper arm forms a deflector extending practically over the entire longitudinal extension. This allows additional functionality. The part taken into account along the longitudinal extension, where the operating button is located, can thus be integrated into the deflector.

[0016] The wiper arm can be equipped with an interchangeable wiper lip, which allows the user to simply replace a worn wiper lip. Thus, according to one possible embodiment, there will be exactly two components: a wiper arm which guarantees structural stability and is connected to the output shaft of an electric motor and a wiping lip made of a rubber-type material and which allows a window, in particular a vehicle windshield, to be wiped.

[0017] The wiper arm comprises means for holding, releasing and replacing the wiping lip.

[0018] The wiping lip engages in the wiping arm along the longitudinal extension of the wiping arm. The wiping lip can be attached directly to the wiping arm so that no intermediate connecting means are required between the wiping arm and the wiping lip. The lip can be removably attached to the wiping arm.

[0019] The wiping arm has a receiving profile which holds the wiping lip and which, during movement on the window, receives the friction forces between the window and the wiping lip. The holding and support of the wiping lip are carried out at least practically over the entire longitudinal extension of the wiping lip. According to a variant, the wiping lip is also supported by only one segment and in particular by several segments for holding and support.

[0020] The wiping arm may comprise a release mechanism. The wiping lip may then be released by an operating button. For this purpose, the wiping lip comprises at least one recess, in particular a cutout or at least one relief. The operating button allows it to engage in the recess or on the relief by means of a fixing element and the wiping lip is fixed in the wiping arm along its longitudinal extension.

[0021] The operating button may be provided at various locations on the wiper arm. The operating button is, for example, provided at the outer end of the wiper arm or near the pivot point of the wiper arm. The operating button may be formed on the wiper arm and be in the form of an elastic tab. The operating button may catch in the engaged position to secure the wiper lip. Alternatively, the operating button depresses to release the attachment.

[0022] The wiper arm can be produced as a single-piece component. According to a variant, the wiper arm consists of several parts and one part comprises the operating button, in particular is produced as an operating button. Brief description of the drawings

[0030] DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0031] [Fig.l] shows, schematically in perspective view, a first embodiment of a wiping device 1 comprising a wiping arm or windshield wiper arm and a wiping lip 3. The wiping device is notably applied to a motor vehicle. The wiping arm 2 makes it possible to pull the wiping lip 3 onto a window, notably the windshield of the vehicle.

[0032] The wiping arm 2 has a fixing body 4. The fixing body is provided with a fixing eyelet 5 for installing an electric motor. The fixing eyelet 5 allows the rotation axis of the wiping arm 2 to be received.

[0033] The wiping arm 2 has a receiving profile 11 open at one end 10 of the arm 2. In this embodiment, the end 10 is opposite the fixing eyelet 5 so that it corresponds to the outer end 10 according to the rotational movement. The profile 11 of the wiping arm 2 extends according to a longitudinal extension 12.

[0034] The wiping lip 3 in the mounted state slides along the longitudinal extension 12 into the receiving profile 11 as shown in [Fig.l].

[0035] [Fig. 2] shows the wiping arm 2 of [Fig. 1] in a schematic perspective view corresponding to the first embodiment. [Fig. 3] shows the wiping lip 3 of [Fig. 1] in a schematic perspective view corresponding to the first embodiment.

[0036] The wiper arm 2 is provided with a fastening device 13 with an operating button 14. The wiping lip 3 has a recess 16. The fastening device 13 comprises a fastening element 17 connected to the operating button 14 and which, in the installed state, comes into the recess 16 of the wiping lip 3.

[0037] [Fig. 3] schematically shows a fixing of the fixing element 17 actuated by the operating button 14 of the wiping arm 2. The fixing element 17 will be fixed to the wiping lip 3 in the open receiving profile 11. With the operating button 14 of the wiping arm 2, the fixing element 17 will be fixed to the wiping lip 3 in the open receiving profile 11. maneuver 14, the fastening installation 13 can be actuated so that the fastening element 17 enters the recess 16 or can be released therefrom.

[0038] [Fig.4] shows the wiping device 1 presented in [Fig.l] according to a detailed view of the replacement of the wiping lip 3. The worn wiping lip 3 can be extracted as indicated by the double arrow 18. Then, a new wiping lip 3 is engaged. Then, for example, by pressing along the arrow 19 and with the hooking of the actuating button 14, the wiping lip 3 is locked. The operating button 14 of this embodiment is located at least practically at the end 10 of the wiping arm 2.

[0039] The operating button 14 of the fixing installation 13 is produced on the wiping arm 2. The wiping arm 2 of this embodiment is in one piece. The operating button 14 can be produced as an elastic tab 15 in one piece with the wiping arm 2.

[0040] To fix the wiping lip 3 to the wiping arm 2, the receiving profile 1 has a fixing slot 20. The wiping lip 3 has a spacer 21 and a holding blade 22 connected to the spacer 21. The receiving profile 11 and the embodiment of the wiping lip 3 on the spacer 21 and the holding blade 22 are adapted to each other.

[0041] The spacer 21 of the wiping lip 3 passes through the fixing slot 20 in the fitted state. This applies to the entire longitudinal extension 12. The holding blade 22 then penetrates from the inside, i.e. from the inside of the receiving profile 11 into this receiving profile 11 of the wiper arm 2.

[0042] The wiping arm 2 is closed by the receiving profile 11 with the exception of the end 10. Only for the receiving profile 11 is the wiping arm 2 open at the end 10. The open section 25 of the receiving profile 11 is designed as the holding blade 22 of the wiping lip 3 and the spacer 21 of the wiping lip 3.

[0043] In this embodiment, the operating button 14 is at the outer end 10 of the wiping arm 2 while the other end 30 is provided with the fixing eyelet 5. Furthermore, the wiping arm 2 is in one piece. The end 10 of the wiping arm 2 is thus opposite the other end 30 of the wiping arm 2.

[0044] [Fig. 5] shows a detail of the wiping device 1 corresponding to a second embodiment. In this embodiment, the wiping arm 2 is in two parts. In addition, the operating button 14 is on a part 31 of the wiping arm 2 which is at least substantially close to the end 10.

[0045] [Fig. 6] shows the wiping device 1 of [Fig. 1] as a detail representation corresponding to a third embodiment. In this embodiment, the end 10 is provided with the fixing eyelet 5.

[0046] The end 10 may be in particular the inner end 10 or the outer end 10. The fixing body 4 is provided with the fixing eyelet 5 at the end 10 ([Fig.6]) constituting the inner end 10 or at the other end 30 (figures 1 to 5).

[0047] A deflector 35 is provided on the wiper arm 2 which extends at least practically over the longitudinal extension 12. The deflector 35 occupies at least substantially the entire longitudinal extension 12. In the case of a wiper arm in several parts as in [Fig. 2], the deflector 35 also occupies at least substantially the entire longitudinal extension 12, that is to say, for example, the part 31.

[0048] The elastic tab 15 can be produced by a U-shaped cutout 40 of the wiping arm 2 or of the part 31 of the wiping arm 2.
