Description

Prior ArtThe invention relates to a wiper device which is used in particular for a motor vehicle. The invention relates in particular to the field of passenger cars (cars) and trucks (trucks).DE 198 54 307 A1 discloses a wiper blade for cleaning motor vehicle windows. The known wiper blade comprises a wiper strip held by a support bracket system.Disclosure of the InventionThe wiping device according to the invention having the features of the main claim has the advantage that an improved configuration and mode of operation are made possible. In this case, a simpler construction of a wiper device and / or a simpler replacement of a wiper lip can be made possible.The measures listed in the dependent claims also result in advantageous refinements and improvements of the features specified in the main claim.It is advantageous that the wiper lip has a recess and that the fixing device has a fixing element connected to the actuating button, which fixing element engages in the recess of the wiper lip in the mounted state. The actuating button can be pressed and then snap-in, so that, for example, a fixing element formed as a projection on the actuating button engages in the recess of the wiper lip and fixes it. The wiper lip is then secured against movement along the longitudinal extent of the wiper arm.It is advantageous that the receiving profile has a fastening slot, that the wiper lip has a web and a retaining strip connected to the web, and that the web of the wiper lip extends through the fastening slot in the inserted state, wherein the retaining strip engages the inside of the receiving profile of the wiper arm. This can ensure a reliable connection which, during operation, keeps the wiper lip in position when the wiper lip is pulled over a pane.It is advantageous that the wiper arm is formed at the end at least substantially closed except for the receiving profile and that an open cross section of the receiving profile is formed at least substantially corresponding to a retaining strip of the wiper lip and a web of the wiper lip. This prevents the penetration of liquids or solids. This can also ensure reliable functioning.It is advantageous that an actuating button is arranged at least approximately at the end of the wiper arm. As a result, the wiper lip can be secured in particular at an outer end which lies on the larger wiper arc. This may optionally facilitate the introduction of the wiper lip. Furthermore, the actuation can be facilitated for a user with respect to a mounting position of the wiper arm on the motor vehicle, in which, for example, a fastening eye is arranged close to the vehicle center.It is advantageous that an actuating button is arranged at least approximately at an inner end of the wiper arm. This makes it possible to facilitate the actuation for a user with respect to the mounting position of the wiper arm on the motor vehicle, in which, for example, a fastening eye is arranged close to a vehicle side.It is advantageous that the actuating button is provided at an outer end of the wiper arm. As a result, the wiper lip can be removed easily without, for example, a connection to an output shaft of an electric motor being in the way. It is also advantageous here that a fastening eye of the wiper arm is formed at an inner end of the wiper arm. This makes it possible to realize an advantageous drive of the wiper arm.It is advantageous that the wiper arm is formed at least substantially in one piece. This allows a robust and simple configuration.It is advantageous that the wiper arm is formed in multiple pieces and that the actuating button is provided on a part of the wiper arm. In this way, in a possible embodiment, the part piece can optionally be exchanged for repair.It is advantageous that the wiper arm has a fastening body on which a fastening eye is formed. As a result, a connection to an output shaft of an electric motor, to a shaft that can be actuated by a linkage or the like can be effected.It is advantageous that a wind spoiler extending at least substantially over the longitudinal extent is formed on the wiper arm. This allows additional functionality. The portion of the wiper arm, which is viewed along the longitudinal extent and in which the actuating button is located, can thereby be incorporated into the wind spoiler.Depending on the configuration, one or more of the following features and advantages can be realized.The wiper arm can be provided with an exchangeable wiper lip, so that simple refilling is possible after the wiper lip has been worn by a user. In this case, in one possible embodiment, exactly two components can be provided: a wiper arm which ensures structural stability and which can be connected to a rotatable output shaft of an electric motor. And a wiper lip, which can be formed from a rubber material or the like and which enables the wiping of a pane, in particular a windshield of a motor vehicle.The wiper arm can have means for holding, releasing and replacing the wiper lip.The wiper lip can be inserted into the wiper arm along a longitudinal extent of the wiper arm. The wiper lip can be fastened directly to the wiper arm. Thus, no indirect connection, for example via a further component between the wiper arm and the wiper lip, is required. The wiper lip can be fastened detachably to the wiper arm.The wiper arm can have a receiving profile which holds the wiper lip and, during a movement over the window, supports it with respect to, for example, frictional forces between the window and the wiper lip. The holding and supporting of the wiper lip can be effected here over at least substantially the entire longitudinal extent of the wiper lip. In a modified embodiment, however, the wiper lip can also be held or supported only in at least one section, in particular in a plurality of sections.The wiper arm can be provided with a release mechanism. The wiping lip can be released by means of an actuating button. For this purpose, the wiper lip can have at least one recess, in particular a cutout, and / or at least one projection. The actuating button can make it possible to engage in the recess or on the projection via a fixing element, which fixes the wiper lip in the wiper arm along its longitudinal extent.The actuating button can be provided at different locations on the wiper arm. For example, the actuating knob can be arranged at an outer end of the wiper arm or close to a pivot point of the wiper arm. The actuating button can be formed on the wiper arm. In this case, the actuating button can be designed as a spring tongue. The actuation button may latch in a depressed position to fix the wiper lip. In a modified embodiment, the actuating button can be pressed in in order to release a fixing.The wiper arm can be designed as a single-piece component. In a modified embodiment, the wiper arm can be formed from a plurality of parts, wherein the actuating button is provided, in particular configured, on one part.Brief Description of the DrawingsPreferred exemplary embodiments of the invention are explained in more detail in the following description with reference to the attached drawings, in which corresponding elements are provided with corresponding reference numerals.
