Preferably, the guide axis is oriented at least practically parallel to the mounting direction. The guide pin extends at least partially along the guide cavity. Preferably, the blocking element has at least an angled or curved basic shape and extends, in particular, at least partially in the direction transverse to the direction of assembly and/or at least substantially in the direction perpendicular to the main axis extending the second wiper blade adapter member into the guide cavity.

Preferably, the other end zone delimits the guide cavity for the blocking element, in particular, along the guide axis. The other end zone extends at least from at least one side of the blocking element oriented in the dismantling direction, in particular along a main axis of extension of the blocking element over at least 10%, preferably over at least 20% and particularly preferably over at least 40% of the total longitudinal extension of the blocking element.

In particular, the blocking element made by its other end zone and the guide pin, an angle of at least 10° and preferably of at least 15° and in a particularly preferential way, an angle at least 20°.

In the end zone and in the other end zone, the blocking element delimits the guide cavity. Preferably, the blocking element is provided on the second adapter element, by the second side of the blocking element which is at least practically parallel to the main axis of extension of the second adapter element of wiper blade. In particular, the blocking element is spaced from the second wiper blade adapter element in at least the other end zone. It is also possible, in particular according to an embodiment of the wiper blade adapter for which the blocking element is made of at least two different materials, that the blocking element, in the end zone, either at least largely made of one material and in the other end region at least largely made of another material, this other material having an elasticity characteristic greater than the elasticity characteristic of the other material.

Advantageously, any movement in the fixed state of the wiper arm adapter other than the movement of the wiper arm adapter on the second wiper blade adapter element is avoided. -glass in the mounting direction.

According to another characteristic, the locking element, in particular in a pivoted position for disassembling the second wiper blade adapter element, preferably, as indicated above, is provided to release the disassembly of the the wiper arm adapter with respect to the wiper blade adapter in the disassembly direction of the wiper arm adapter, in particular, by movement with respect to the second member wiper blade adapter and/or by elastic deformation releasing the guide cavity for the guide extension. In particular, the direction of disassembly is opposite to the direction of assembly, in particular it is antiparallel to the direction of assembly. Preferably, the blocking element releases by an elastic deformation, in particular of the other end zone with respect to the end zone, in at least one direction practically perpendicular to the main axis of extension of the second wiper blade adapter and with respect to the mounting direction, to clear the guide cavity for the guide extension. Preferably, the guide extension in the released state of the locking element, moves along the dismantling direction, in particular, along the guide axis to exit the guide cavity.

It is also possible to envisage mounting the blocking element, in a movable manner, on the second wiper blade adapter element and in particular, the blocking element to release the guide cavity at least in large part, to exit the guide cavity. In particular, according to a development of the secure fastening unit, the locking element is movably mounted on the second wiper blade adapter element such that the locking element is biased by a spring, in particular by a return element of the secure fixing unit and in particular the blocking element preferably after a movement of the guide extension out of the cavity, towards a state of the blocking element in applying a restoring force. Any accidental detachment of the wiper arm adapter in the pivoted dismantling position is advantageously avoided. This allows quick and easy removal of the wiper arm adapter.

According to another characteristic, the blocking element is produced in such a way that, in particular in a pivoted dismantling position, preferably like that indicated above, of the second wiper blade adapter element, the arm adapter wiper arm can preferably be moved in the guide extension in a dismantling direction of the wiper arm adapter by overcoming the holding force of the locking member, along the cavity of guidance. Preferably, the holding force is the force that must be applied to bring the locking element into a released state in the guide cavity, in particular to move it and/or deform it. Preferably, the blocking element and/or the guide extension are made in such a way that the blocking element is oriented transversely, in particular practically perpendicular to the direction of dismantling and/or of the guide axis by being urged in this direction by the holding force. Preferably, the blocking element, in its state releasing the guide cavity, is at least largely outside the guide cavity. In particular, the guide extension in the state of the blocking element for releasing the guide cavity can move without being retained along the guide cavity. It is also possible to envisage making the blocking element so that the holding force is greater at least than the weight of the wiper blade adapter and/or the wiper arm. Advantageously, any accidental detachment of the wiper arm adapter in the pivoted dismantling position is thus avoided.

According to another characteristic, the blocking element has a contact surface, in particular transverse to the main plane of extension of the second wiper blade adapter element, this surface being provided so that when dismantling the wiper arm adapter, in particular in a pivoted dismantling position, preferably like that mentioned above, of the second wiper blade adapter element, it can be moved by the guide extension in stressing the contact surface, in particular by at least partial deformation. The expression "main extension plane" of a component, in particular of the second wiper blade adapter element, is a plane parallel to the largest lateral surface of the smallest parallelepiped which still completely surrounds the component or the part, in particular, which passes through the center of the parallelepiped.

Preferably, the contact surface is in the other end zone of the blocking element, in particular, on one side of the blocking element delimiting the guiding quality. In a particularly preferential manner, the contact surface is at least largely, in particular practically completely, in the form of a flat surface. Preferably, the locking element has at least one end delimiting the contact surface in the direction of dismantling, in particular in the other end zone, a rounded edge by which, in particular, the guide extension moves when removing the wiper arm adapter. Advantageously, there will be a simple and economical production of the blocking element and/or of the guide extension. This allows quick and easy removal of the wiper arm adapter.

According to another characteristic, the locking element and/or the wiper blade adapter are made and/or arranged so that the guide extension, at least in the mounted state of the arm adapter, wiper, is spaced from the blocking element, in particular by being on the first wiper blade adapter element. The mounted guide extension of the wiper arm adapter is outside the other guide cavity. In particular, the mounted guide extension of the wiper arm adapter lies against the stop element.

Particularly preferably, in the pivoted disassembly position, the guide extension is movable in the guide cavity and a movement with the locking element in the direction of assembly, in particular, by the contact surface, allows the setting contact. There is an advantageously secure fixing of the wiper arm adapter to the wiper blade adapter, in particular because any accidental cooperation of the guide extension and the locking element is avoided. Wear and/or accidental damage to the blocking element by the guide extension is advantageously avoided. This provides very high reliability for the blocking element.

According to another characteristic, the secure fixing unit comprises at least one other locking element on the second wiper blade adapter element; it is provided on the side of the second wiper blade adapter member opposite to the locking member, parallel to the mounting direction of the wiper arm adapter as well as preferably the wiper blade adapter extension main axis as indicated above, in particular, the second wiper blade adapter member. In particular, the second wiper blade adapter element delimits at least a second guide cavity and a second other guide cavity which are in particular on one side of the second wiper blade adapter element which is opposite to the guide cavity and parallel to the mounting direction of the wiper arm adapter and the main extension axis of the second wiper blade adapter member. Preferably, the wiper arm adapter has at least one other guide extension which is in particular on the wiper arm adapter, on the side of the wiper arm adapter. that is parallel to the wiper arm adapter mounting direction and the wiper arm adapter extension main axis.

To release the guide cavity and the other guide cavity considered along the mounting direction, the blocking element and the other blocking element are movable and/or deformable in another direction, they are in particular turned l towards each other, in particular of the main axis of extension of the second wiper blade adapter element. The blocking element and the other blocking element are identical and/or of the same construction. Preferably, the guide cavity and the second guide cavity are symmetrical with respect to the main plane of extension of the wiper blade adapter. Preferably, the other guide cavity and the second other guide cavity are made symmetrically with respect to the main plane of extension of the wiper blade adapter. In particular, the abutment element and the other abutment element are identical and/or of the same construction. The attachment of the wiper arm adapter to the wiper blade adapter will advantageously be secure and robust, in particular in that the wiper arm adapter and the wiper blade adapter wiper levers, during movement of the wiper device, will be regularly acted upon by force. This makes it possible to have an advantageously low stress on the locking element and/or the second wiper blade adapter element in a direction deviating from the direction of disassembly and/or the direction of assembly . This guarantees an advantageously high reliability of the blocking element.

According to another characteristic, the blocking element, starting from at least one side of the second wiper blade adapter element provided with the blocking element, extends at least in large part at least practically parallel to the guide pin advantageously mentioned above of the second wiper blade adapter element in particular along a direction of disassembly, in particular that mentioned above of the wiper arm adapter. Preferably, the blocking element has at least a maximum transverse extension in a direction essentially parallel to the main axis of extension of the second wiper blade adapter element, this transverse extension being in particular smaller than the maximum transverse extension of the guiding cavity. In particular, the second wiper blade adapter element delimits at least one cavity which extends in particular from the side of the second wiper blade adapter element provided with the blocking element to an upper side of the second wiper blade adapter member oriented substantially perpendicular to the mounting direction.

In a particularly preferential manner, the blocking element is at least largely in the cavity. The blocking element is provided so that, during a movement and/or a deformation to release the guide cavity, it is at least partially, in particular largely, moved in the cavity. The stability and robustness of the locking element are particularly high for elastic deformation by the guide extension. This guarantees a very high reliability of the blocking element. One can also have a guaranteed and reliable attachment of the wiper arm adapter to the wiper blade adapter.

The invention also relates to a windscreen wiper comprising a windscreen wiper device as defined above. The wiper consists of the wiper blade and the wiper arm. Preferably, the wiper blade is attached to the wiper arm by the wiper blade adapter and the wiper arm adapter. The wiper blade is movable relative to the wiper arm via the wiper blade adapter, in particular via the first wiper blade adapter member and the second wiper blade adapter member; it is in particular mobile by pivoting. Preferably, the wiper blade is detached from the wiper arm by the wiper device in the pivoted dismantling position. The realization of the wiper according to the invention advantageously allows to have a simple and guaranteed connection of the wiper blade to the wiper arm.

The windscreen wiper device advantageously avoids any error in mounting the windscreen wiper blade to the windscreen wiper arm. This advantageously improves the comfort of use, that is to say the mounting of the wiper blade on the wiper arm, in particular because the user has an identified assembly process without equivocal to fix the wiper blade. This allows advantageously quick assembly of the wiper blade.

The windscreen wiper device according to the invention and/or the windscreen wiper according to the invention are not limited to the application to the embodiment described above. The windscreen wiper device and the windscreen wiper according to the invention may have a number of component elements or units different from those mentioned above without departing from the scope of the invention.
