"Working state" should preferably be understood as a state in which the wiper blade assembly is ready to perform the wiping process and / or wiping operation and / or is in the process of wiping, during which the wiper blade assembly, especially the wiper blade system, especially the wiper blade, especially the wiper blade unit of the window glass wiper, is preferably guided on the vehicle window glass and advantageously abuts against the vehicle window glass.

[0005] Preferably, the windshield unit has at least two spoiler end components. Preferably, these spoiler end components each have a concave outer side for wind deflection, and particularly for using wind force to press the wiper blades against the window glass. Preferably, the concave outer side forms a unique spoiler shape. Alternatively, these spoiler end components may have at least a substantially flat outer side, particularly on the side facing away from the wiper blade assembly's elastic rail.

[0006] Preferably, the wiper blade is connected to the wiper arm and is oscillating about an axis of rotation, particularly at least 15°. Preferably, this axis of rotation is oriented at least substantially perpendicular to the longitudinal axis of the wiper blade, particularly the windshield unit. The “longitudinal axis” of the object should preferably refer to an axis extending parallel to the longest side of the smallest geometric cube that just completely surrounds the object. The term “substantially perpendicular” should preferably define an orientation relative to a reference direction, wherein this direction and the reference direction, particularly when viewed in the projection plane, form an angle of 90°, which has a maximum deviation particularly less than 8°, advantageously less than 5°, and particularly advantageously less than 2°.

[0007] Wiper blade assembly can be designed as a single wiper blade. Specifically, wiper blade assembly can have a wiper strip unit. Specifically, wiper blade assembly can have one or two flexible rails. Specifically, wiper blade assembly can have two end caps.

[0008] Preferably, at least two separately constructed adapter bases are respectively configured to connect to exactly one of the spoiler end components. Preferably, each adapter base is directly connected to one of the spoiler end components in the operating state. Preferably, these adapter bases are connected to a spoiler end component spaced apart from each other in the operating state. "Adapter base" should in particular refer to a component of a wiper blade adapter that is directly, particularly substantially immovably connected to at least one component of the windshield unit, and / or that component, particularly along the longitudinal axis of the windshield unit, connects two components of the windshield unit to each other, and / or that component, particularly at least substantially, is arranged in a space preferably defined by the entire connecting line between the two components of the windshield unit, and / or that space, particularly in a cross section perpendicular to the longitudinal axis of the windshield unit, is substantially abutting the periphery of at least one component of the windshield unit, particularly one of the spoiler end components, along the periphery of at least one component of the windshield unit—to which the windshield unit is connected—and is substantially similar in shape to the windshield unit. Preferably, at least one adapter base is directly connected to at least one elastic rail of the wiper blade, particularly the wiper blade assembly.

[0009] Preferably, the at least two adapter bases are arranged offset from each other along the longitudinal axis of the windshield unit, at least in the operating state. Preferably, the at least two adapter bases are connected to the windshield unit, particularly the spoiler end component, offset from each other along the longitudinal axis of the windshield unit, at least in the operating state. Preferably, the at least two adapter bases are arranged without contact along the longitudinal axis of the windshield unit, at least in the operating state. Alternatively, the at least two adapter bases can be arranged with at least partial contact along the longitudinal axis of the windshield unit, at least in the operating state, particularly within the space between two components of the windshield unit, and particularly connected to the windshield unit. Preferably, the wiper blade adapter has two adapter bases. These adapter bases can each be without at least one electrical and / or at least one fluid connection. Preferably, at least one of the adapter bases has a wiper arm connection connection and / or is coupled to the wiper arm connection connection.

[0010] According to the design of the wiper blade assembly according to the invention, advantageously durable engagement schemes, particularly connection schemes, for the wiper blade adapter, such as with the wiper arm, are possible. Specifically, the various engagement components can be advantageously distributed along the longitudinal axis of the windshield unit, particularly spaced apart from each other, and especially advantageously separated from each other by means of the windshield unit's components. Accessibility of the various components of the wiper blade adapter is achieved. Particularly advantageously, the risk of complex engagement configurations between the wiper arm and the wiper blade adapter can be reduced. In particular, the adapter base of the wiper blade adapter can advantageously support the flexibility of the windshield unit through a design of at least two components.

[0011] Furthermore, it is proposed that the windshield unit includes at least one spoiler intermediate component configured for connection to an adapter base. Preferably, the at least one spoiler intermediate component is configured for direct connection to at least two adapter bases. Preferably, the at least one spoiler intermediate component, in its operational state, allows at least two adapter bases to be interconnected. Preferably, the at least one spoiler intermediate component is designed without a concave outer surface, which in particular can form a unique spoiler shape for using wind power to press the wiper blades against the window glass. Preferably, the at least one spoiler intermediate component is made of the same material as the at least two spoiler end components. The at least one spoiler intermediate component is arranged coaxially with the spoiler end components. Preferably, the spoiler intermediate component has at least two fluid channels for connection to the at least two adapter bases. Preferably, the spoiler intermediate component has at least two plug notches for connection to one of the at least two adapter bases. Preferably, the plug notches of the spoiler intermediate component for connection to the at least two adapter bases are formed by the fluid channels of the spoiler intermediate component. Preferably, each of the at least two adapter bases has at least one, preferably at least two, fluid channels. Preferably, each of the at least two adapter bases has at least four connecting protrusions. Preferably, each of the at least two adapter bases has at least two connecting protrusions for connection to the intermediate spoiler component. Preferably, each of the at least two adapter bases has at least two connecting protrusions for connection to the end spoiler component. Preferably, the connecting protrusions of the adapter bases are formed by the fluid channels of the adapter bases. Preferably, the end spoiler component and the adapter bases are fluidly connected to each other. Preferably, each end spoiler component has at least two fluid channels. Preferably, the fluid channels of the end spoiler components form two plug notches for connecting the end spoiler component to the two connecting protrusions of each adapter base. Preferably, especially at least in the operating state, the extension of the at least one intermediate spoiler component along the longitudinal axis of the windshield unit is shorter than the extension of the end spoiler component, particularly along the longitudinal axis of the wiper blade. Preferably, especially at least in the operating state, the extension of the at least one spoiler intermediate component along the longitudinal axis of the windshield unit is at most 20%, preferably at most 10%, of the extension of these spoiler end components, especially one of the spoiler end components, particularly along the longitudinal axis of the wiper blade. Preferably, especially at least in the operating state, these spoiler end components are designed to be of equal length along the longitudinal axis of the wiper blade. Alternatively, the wiper blade adapter can have at least one other adapter base or, particularly, a component not belonging to the windshield unit or the wiper blade adapter, which adapter base / component is configured to connect, particularly directly, to two other adapter bases. This allows for an advantageously uncomplicated connection between the adapter base and the windshield unit.In particular, it enables an advantageous distribution of the wiper blade adapter along the longitudinal axis of the wiper blade, especially in terms of functional distribution.

[0012] Furthermore, it is proposed that one of the adapter bases includes at least one electrical connection. Preferably, exactly one of the at least two adapter bases has an electrical connection. The electrical connection can have, for example, one, two, three, or four engagement configurations, such as, in particular, plug and socket. Preferably, at least in the operating state, the electrical connection is arranged along the longitudinal axis of the adapter base, particularly along the longitudinal axis of the wiper blade, at one end of the adapter base. Preferably, at least in the operating state, the electrical connection is arranged along the longitudinal axis of the adapter base, particularly along the longitudinal axis of the wiper blade, at the end of the adapter base facing the other adapter base. Preferably, particularly at least when viewed along the longitudinal axis of the wiper blade, the engagement side of the at least one electrical connection, particularly the plug side used for connection with the electrical connection, is oriented away from at least one other adapter base. Preferably, particularly at least when viewed along the longitudinal axis of the wiper blade, at least one engagement side of the at least one electrical connection is oriented towards the spoiler end component, particularly the adapter base having the electrical connection is directly connected to the spoiler end component. Preferably, the electrical connection point of at least one of the adapter bases is designed as at least one plug and socket. Alternatively, the at least two adapter bases can be designed without an electrical connection point. This allows for the realization of advantageous functions of the adapter bases, particularly the at least one adapter base.

[0013] Furthermore, it is proposed that the at least one electrical connection has a engagement direction, particularly as already mentioned, oriented at an angle of at least 5° relative to the longitudinal axis, particularly as already mentioned, of the windshield unit, particularly the corresponding adapter base. Preferably, the at least one electrical connection has an engagement direction oriented at an angle of at least 7.5°, preferably at least 10° relative to the longitudinal axis, particularly the corresponding adapter base of the windshield unit. Preferably, the at least one electrical connection has an engagement direction oriented at an angle of at most 50°, preferably at most 40°, particularly preferably at most 20°, and more particularly preferably at most 15° relative to the longitudinal axis, particularly the corresponding adapter base of the windshield unit. An advantageously achievable engagement direction, particularly a plug direction, is possible for the electrical connection, which is particularly designed as at least one plug and socket.

[0014] Furthermore, it is proposed that the adapter base, including at least one electrical connection, has no fluid connection, and / or no wiper arm connection, as specifically mentioned. Preferably, the wiper arm connection is at least one mechanical connection through which the wiper arm can be connected to the wiper blade preferably without loss of contact, and particularly with the ability to swing at least 10°. The wiper arm can be connected directly or indirectly to the wiper arm connection. The wiper arm connection can be a mechanical connection provided for connection to at least one component of the wiper blade adapter, through which the wiper arm can be connected to the adapter base particularly without loss of contact and / or with the ability to swing. Preferably, the wiper arm connection is designed as two swinging protrusions, particularly axial protrusions, particularly aligned and oriented away from each other. Preferably, the wiper blade adapter includes at least two components, different from those of the adapter base, for connecting the wiper arm to the adapter base, which has the wiper arm connection. Preferably, one of the two components different from the adapter base is a connector, which is specifically configured to be directly and oscillatingly connected to the corresponding adapter base at the wiper arm connection junction. Preferably, one of the two components different from the adapter base is a cover, which is specifically configured to be directly and movably connected to the connector. Preferably, the adapter base including the at least one electrical connection has no other connection related to a particularly direct connection with a component that is either a connector associated with the wiper arm or the wiper arm itself. An adapter base including at least one electrical connection can include a purely mechanical connection, different from the wiper arm connection junction, which, for example, allows a movable component of the wiper blade adapter, such as a cover, to lock onto the corresponding adapter base, but the wiper arm can be connected to the wiper blade, particularly not without loss, through this purely mechanical connection. Preferably, an adapter base without at least one electrical connection includes a wiper arm connection junction. It is possible to achieve an electrical connection that is advantageously exposed on the wiper blade, especially when the wiper blade is mechanically connected to the wiper arm.

[0015] Furthermore, it is proposed that one of the adapter bases includes at least one fluid junction. Preferably, exactly one of the at least two adapter bases has a fluid junction. This fluid junction can have, for example, one, two, three, or four engagement configurations, such as plugs and sockets, particularly engagement openings. Preferably, at least in the operating state, the fluid junction is arranged along the longitudinal axis of the adapter base, particularly along the longitudinal axis of the wiper blade, at one end of the adapter base. Preferably, at least in the operating state, the fluid junction is arranged along the longitudinal axis of the adapter base, particularly along the longitudinal axis of the wiper blade, at one end of the adapter base facing another adapter base. Preferably, particularly at least when viewed along the longitudinal axis of the wiper blade, the engagement direction of at least one fluid junction is oriented towards at least one other adapter base. Preferably, particularly at least when viewed along the longitudinal axis of the wiper blade, at least one engagement direction of at least one fluid junction is oriented away from the spoiler end component, particularly since the adapter base having the fluid junction is directly connected to the spoiler end component. Preferably, the fluid junction of at least one of the adapter bases is designed as at least one plug / socket. Alternatively, the at least two adapter bases can be designed without a fluid junction. Preferably, the fluid junction protrudes from the respective adapter base. Preferably, in the operating state, the fluid junction extends along the longitudinal axis of the wiper blade, particularly the windshield unit, at least through a large portion of the spoiler intermediate component. Preferably, in the operating state, the fluid junction, viewed along the longitudinal axis of the wiper blade, particularly the windshield unit, covers a portion of the spoiler intermediate component perpendicular to the longitudinal axis of the wiper blade. This allows for the advantageous separation of the adapter bases, particularly at least one adapter base.

[0016] Furthermore, it is proposed that the fluid junction has a mating direction oriented at an angle of at least 5° relative to the longitudinal axis of the windshield unit, particularly the corresponding adapter base, as already mentioned. Preferably, the at least one fluid junction has a mating direction oriented at an angle of at least 7.5°, preferably at least 10° relative to the longitudinal axis of the windshield unit, particularly the corresponding adapter base. Preferably, the at least one fluid junction has a mating direction oriented at an angle of at most 50°, preferably at most 40°, particularly preferably at most 20°, and even more particularly preferably at most 15° relative to the longitudinal axis of the windshield unit, particularly the corresponding adapter base. An advantageously achievable mating direction, particularly a plug direction, is possible at the fluid junction, which is specifically designed as at least one plug-and-receptacle.

[0017] Furthermore, it is proposed that the adapter base, including at least one fluid interface, has no electrical interface. Preferably, the adapter base including at least one fluid interface includes a wiper arm connection interface. The adapter base including at least one fluid interface can include a purely mechanical interface, unlike the wiper arm connection interface, which is used for locking movable components of the wiper blade adapter, such as covers, onto the corresponding adapter base, but the wiper arm can be connected to the wiper blade, particularly not without loss, through this purely mechanical interface. Preferably, the adapter base without at least one fluid interface has no wiper arm connection interface. It is possible to achieve a fluid interface that is advantageously accessible on the wiper blade when the wiper blade is mounted on the wiper arm.

[0018] Furthermore, it is proposed that the wiper blade adapter has at least one connector, particularly as already mentioned, which is configured to be oscillatingly connected to one of the adapter bases, particularly at the wiper arm connection junction. Preferably, the connector is oscillatingly connected directly to the adapter base at the wiper arm connection junction, particularly in the operating state, which in particular has a wiper arm connection junction and / or a fluid connection junction. Preferably, the connector has two opposing, particularly circular, notches, which are specifically configured to allow the connector and the adapter base to be oscillatingly connected at the wiper arm connection junction. This enables the wiper blade to oscillate advantageously relative to the wiper arm, particularly during installation, thereby advantageously reaching the fluid and / or electrical connection junction for engaging the corresponding connection.

[0019] Furthermore, it is proposed that the engagement direction at the fluid junction, specifically mentioned above, on one of the adapter bases is oriented at least substantially parallel to the engagement direction at the electrical junction, specifically mentioned above, on the other adapter base. "Substantially parallel" here should specifically refer to an orientation in a plane relative to a reference direction, wherein this direction has a deviation of particularly less than 8°, advantageously less than 5°, and particularly advantageously less than 2° relative to the reference direction. Preferably, the engagement direction at the fluid junction on one of the adapter bases is oriented in the same way as the engagement direction at the electrical junction on the other adapter base. Preferably, the engagement directions at the fluid junction and the electrical junction are oriented at an angle between 5° and 15° relative to the longitudinal axis of the wiper blade. This enables advantageously implementable plug movement.

[0020] Furthermore, it is proposed that the wiper blade adapter has at least one cover, particularly as mentioned above, which is configured for a locking connection with the wiper arm, particularly as mentioned above, and the cover is connected to the connecting body. Preferably, the cover is directly, particularly relatively movable, connected to the connecting body, at least in the operating state. Preferably, the wiper arm can be directly connected to the cover via a locking connection, at least substantially immobile, particularly immobile along the longitudinal axis of the wiper arm by at least a maximum of 1 mm. Preferably, the wiper arm is directly connected to the cover via a locking connection, at least substantially immobile, particularly immobile along the longitudinal axis of the wiper arm by at least a maximum of 1 mm. Preferably, the cover has at least one locking component, particularly for locking the wiper arm. An advantageous wiper arm engagement mechanism can be achieved.

[0021] Furthermore, the present invention provides a windshield wiper system comprising a wiper arm and a wiper blade assembly according to the invention. Preferably, the wiper arm has a locking notch for locking with a locking component of a cover. This advantageously enables mutually compatible components of the windshield wiper system.
