[0005] Cover device for a window recess of a motor vehicle door

[0006] Description

[0007] The invention relates to a covering device for a window recess of a motor vehicle door, a motor vehicle door and a motor vehicle.

[0008] There is a need for vehicles with door handles that are aesthetically pleasing while simultaneously meeting safety regulations. So-called flush-mounted handles or door handles at least partially satisfy these design requirements. However, they must also comply with safety regulations. It is particularly important that first responders can access the occupants from outside the vehicle in an emergency. With doors featuring minimalist handles or flush-mounted handles recessed into the bodywork, it can be difficult for first responders to gain access to the vehicle in an emergency.

[0009] From FR 3096713 A1 and DE 102019 117779 A1, handle arrangements are known that feature a minimalist design and allow electronic actuation of the locking device. A disadvantage of the disclosed handle arrangements is the engagement area, which is always open at the top and susceptible to dirt and accidental operation, particularly in car washes.

[0010] It is therefore an object of the present invention to overcome at least one of the disadvantages described above, at least partially. In particular, it is an object of HU49821 12.11.2024 ßols & Vogel

[0011] Invention to provide a cover device with an actuating unit that reliably protects against incorrect operation and dirt in a minimalist design.

[0012] The aforementioned problem is solved by a covering device according to a first aspect of the present invention, by a motor vehicle door according to a second aspect of the present invention, and by a motor vehicle according to a third aspect of the present invention. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings. Features and details described in connection with the covering device according to the invention naturally also apply in connection with the motor vehicle door and / or the motor vehicle according to the invention, and vice versa, so that the disclosure relating to the individual aspects of the invention always includes, or allows for, reciprocal reference.

[0013] According to a first aspect, the present invention relates to a covering device for a window recess of a motor vehicle door, comprising a base body for at least partially covering the window recess and an engagement recess of the motor vehicle door, wherein the base body has an actuating section with a grip recess for a user's hand and wherein an actuating unit is provided for actuating a closing device of the motor vehicle door by means of the user's hand.

[0014] In this context, a window shaft is to be understood as a shaft or cavity in the vehicle door, wherein a window of the vehicle door can be lowered, at least partially, into the window shaft during an opening process.

[0015] The cover devices according to the invention offer the advantage that the door opening function can be integrated into a cover device and thus provided discreetly yet user-friendly on a vehicle. Covers for window recesses are proven elements for the exterior design of a vehicle. In this respect, the door opening function is discreetly integrated into the overall appearance of the vehicle. Disturbing gaps or edges in the outer skin of the vehicle door can be eliminated in this way, resulting in a homogeneous overall impression of the vehicle as well as improved aerodynamics due to reduced wind resistance. In addition to the function of covering the window recess, HU49821 12.11.2024 ßols & Vogel

[0016] The cover device according to the invention offers the advantage that the recessed grip on the vehicle door is at least partially covered and / or concealed. This means that the cover device specifically covers a gripping area or recess on the door, wherein the gripping area, and thus the recess, is located in the area of ​​the window pane. For this purpose, a concave area, i.e., a depression, can be provided in the outer door panel or the outer skin of the vehicle door, which differs accordingly from the rest of the vehicle door's external appearance. Because the cover device at least partially covers this depression, the area is also protected from external environmental influences.

[0017] Furthermore, the cover device offers the advantage that no recess for attaching the door handle is required on the vehicle door, particularly on the outer door panel. The cover device, which is positioned and preferably attached to the window channel, can also be mounted to the outer door panel without additional fastening.

[0018] The motor vehicle door can preferably be designed as a side door, specifically a front or rear passenger door, but within the spirit and scope of the present invention any vehicle door, including swing doors or tailgates, bonnets, side sliding doors, tailgates, rear doors, gullwing doors or the like, can be included.

[0019] The window channel of a motor vehicle is the upper section of the vehicle door through which the window pane is guided as it moves up or down. Typically, the window channel is designed to ensure the guidance and sealing of the window pane while maintaining the structural integrity and airtightness of the door. The geometry of the window channel is adapted to the contours of the pane and the door panel so that they fit and close seamlessly.

[0020] The cover device, also known as a window channel strip or channel profile, is preferably integrated into this channel and forms the transition surface between the window pane and the external vehicle environment. It can comprise a composite material, e.g., elastomers and metal or plastic inserts. The strip is advantageously in HU49821 12.11.2024 ßols & Vogel

[0021] The cover is designed with a U- or L-shaped cross-sectional geometry so that it rests against both the outer and inner sides of the door panel and completely covers the window recess. The term "base body" refers in particular to the part of the cover that forms the outer section.

[0022] In addition to sealing, the cover can provide mechanical guidance, stabilizing the movement of the window pane in its horizontal and vertical position. The inner part of the strip often features sliding surfaces or coatings to minimize friction during pane movement and reduce wear. At the outer end, the window channel strip is often integrated into the outer door trim or mounted flush with it, resulting in an aerodynamically efficient and aesthetically pleasing design.

[0023] The term "locking device" refers specifically to an electrically operated locking device. An electrically operated locking device is characterized by the fact that the locking mechanism (rotary latch and at least one pawl) can be opened by an electric motor. For this purpose, an electric motor preferably acts directly or indirectly on the pawl and moves it out of the locked position (pre-latch and / or main latch position). It may be provided that at least one release lever is arranged between the electric motor and the pawl, by means of which the pawl can be moved out of the locked position. Electrically operated locks (also called "e-latches") can thus be opened even without mechanical external and / or internal operation. It is therefore possible to dispense with mechanical internal and / or external door handles with a mechanical connection to the locking device.

[0024] According to the invention, the cover device of a motor vehicle comprises an actuating section that is integrated into a defined area of ​​the vehicle door and thus into the cover device. The actuating section is arranged, or can be arranged, in an area on the vehicle door that has an ergonomic recess for gripping, allowing the user to insert and grasp a hand. The recess is functionally and geometrically integrated into the door panel, providing an intuitive and comfortable grip. This creates a defined, accessible space within the cover device that can be used to actuate a door component. HU49821 12.11.2024 ßols & Vogel

[0025] It can. Preferably, it is a concave area, i.e., a recess, in or on the bodywork of the motor vehicle door.

[0026] The actuation section is designed as a defined area of ​​the cover device, which is mechanically and / or electronically adapted to the desired interaction. When touched or pressed by the user, this section can trigger sensory signals that detect an access request and react accordingly.

[0027] Positioning the actuation element within the cover mechanism allows for seamless integration into the vehicle's contours, while its proximity to the user's hand during typical door opening processes enhances functionality. Particularly in minimalist vehicle doors, this area can be utilized as an operating point via an actuation unit and the recessed grip, enabling the door component to respond to user interaction.

[0028] The user's hand is inserted from below into the recessed grip, simultaneously gaining access to a recessed grip integrated into the cover's base. This grip is formed within the cover's base and allows the user a particularly firm and / or ergonomically adapted grip. The downward insertion of the hand into the recess allows for intuitive access to the grip, enabling controlled and precise operation of the actuating section. Furthermore, the recessed grip and the recessed grip are better protected from external environmental influences or the effects of a car wash.

[0029] "From below" in this context means that the handle recess of the cover device is oriented so that its opening faces the underside of the vehicle or the road. This downward-facing position effectively protects the handle recess from external environmental influences such as rain, dirt, or dust particles, which would typically accumulate on horizontal or upward-facing surfaces. Furthermore, this orientation ensures that the handle recess remains reliably protected even in car washes, preventing accidental or unwanted activation by components of the car wash. HU49821 12.11.2024 ßols & Vogel

[0030] This can be reliably prevented or at least reduced. The underside arrangement thus contributes to durability and functional reliability.

[0031] The actuation, and thus the triggering of the change of state at the locking device, is achieved via an actuating unit. This actuation, and thus the change of state, can preferably be triggered electrically. In other words, it can be provided that at least the actuating unit is operatively connected to the locking device in such a way that the change of state can be triggered electrically. In particular, electrical triggering in this context is understood to mean triggering by the transmission of electrical signals or impulses.

[0032] Alternatively, the change of state can be triggered electromechanically. An electromechanical release can be implemented, for example, by a mechanical actuating unit in conjunction with an electrical release device, in particular a switch or microswitch, wherein the electrical release device can be actuated by the mechanical actuating unit and wherein the electrical release device is connected to the locking device in such a way that the change of state can be triggered electrically.

[0033] Alternatively, the change of state can be triggered mechanically. A mechanical release can be achieved, for example, by a mechanical actuating unit in conjunction with a mechanical release mechanism. The mechanical release mechanism can be, for example, a cable or a Bowden cable, which is connected on one side to the mechanical actuating element and on the other side to the locking device in such a way that the change of state can be triggered by actuating the actuating element.

[0034] Additionally or alternatively, it can be provided that an actuation of at least one actuating unit can initiate a drive-assisted or automatic door opening and / or closing of at least one vehicle door. The automatic door opening can preferably be carried out by at least one door drive. In other words, it can be provided that the at least one actuating unit, in particular the actuating unit arranged in the actuating section, can trigger a drive-assisted or automatic door opening and / or closing of at least one vehicle door. HU49821 12.11.2024 ßols & Vogel

[0035] is designed. In this context, "door opening" refers to the movement of the vehicle door from a closed position to an open position, and "door closing" refers to the reverse movement of the vehicle door from the open position to the closed position. Specifically, a door closing can be initiated when the vehicle door is in an open position, and a door opening can be initiated when the vehicle door is in a closed position.

[0036] Within the scope of the invention, it can be advantageous for the actuating unit to comprise an actuating mechanism for the mechanical actuation of the locking device and / or the vehicle door and / or actuating electronics for the electronic actuation of the locking device. Mechanical actuation by means of an actuating mechanism thus enables so-called external actuation of the locking device. Mechanical actuation is, firstly, cost-effective to implement and can be operated independently of a power supply. Furthermore, the actuating unit allows the door to be mechanically moved from the closed position to a slightly ajar and / or open position by the user exerting a pulling force on the actuating unit.

[0037] Alternatively or additionally, an actuating electronic unit can be provided for the electrical or electronic operation of the locking device. Actuating electronic units are specifically provided for use with an electrically operated locking device. An electrically operated locking device is characterized by the fact that the locking mechanism (rotary latch and at least one pawl) can be opened by an electric motor. For this purpose, an electric motor preferably acts directly or indirectly on the pawl and moves it out of the locked position (pre-latch and / or main latch position). It may be provided that at least one release lever is arranged between the electric motor and the pawl, by means of which the pawl can be moved out of the locked position. Electrically operated locks (also called "e-latches") can therefore be opened even without mechanical external and / or internal operation.It is therefore possible to dispense with mechanical interior and / or exterior door handles with a mechanical connection to the locking mechanism. The actuation electronics are consequently designed to actuate and thus trigger the state change at the electrically operated locking device (e-Latch). The actuation and thus the state change can therefore be triggered electrically. HU49821 12.11.2024 ßols & Vogel.

[0038] Within the scope of the invention, it is conceivable that, for mechanical actuation, the actuating unit is movably mounted on the base body in the actuating section and operatively connected to the actuating mechanism, so that the actuation of the closing device can be achieved by moving the actuating unit relative to the base body. Thus, the actuating unit is designed to be foldable or pivotable. This means that the actuating unit can be folded from its rest position to its operating position. The actuating unit is therefore fundamentally designed to be foldable about an axis. Accordingly, the position of the actuating unit can be changed, at least partially. This allows the actuating unit, in its rest position, to create a gap between the cover device and the actuating unit, from its at least substantially flush arrangement with the cover device.

[0039] Within the scope of the invention, it may be provided that the actuating mechanism includes a connecting element, in particular a Bowden cable or a rope, wherein the connecting element mechanically connects or can connect the actuating unit to the locking device. A mechanical release can be realized, for example, by a mechanical actuating unit in conjunction with a mechanical release means. The mechanical release means can, for example, be designed as a rope or a Bowden cable that is operatively connected on the one hand to the mechanical actuating element and on the other hand to the locking device in such a way that the change of state can be triggered by actuating the actuating element.

[0040] It is further conceivable that the actuating electronics comprise at least one sensor unit with at least one sensor. Within the scope of the invention, it can be advantageous for the sensor unit to include at least one sensor, wherein a user's access request can be detected by means of the sensor and an unlocking and / or opening signal and / or a locking or closing signal / blocking signal for the locking device can be generated. Consequently, a user's access request can be detected by means of the sensor. Thereupon, the locking device and / or a door control unit is activated, and the locking device is unlocked and / or opened or locked and / or closed or blocked. "Locking and unlocking" can be understood as the actuation of a central locking system, and "opening or blocking" as the opening or blocking of the locking mechanism. HU49821 12.11.2024 ßols & Vogel

[0041] The sensor unit is therefore designed to detect a user's approach to or contact with the actuating unit and the associated access request. In particular, the sensor is designed to detect a user touching the actuating unit. The sensor and / or sensor unit can be located on the outer side (facing away from the vehicle door) and / or inner side (facing the vehicle door) of the actuating unit. It is also conceivable that the sensor and / or sensor unit is located adjacent to the actuating unit.

[0042] It is also conceivable that the sensor generates a signal for a door drive. Consequently, the sensor or sensor unit can supply a door drive and / or a door control unit with a signal such that the door drive moves the door from a closed position to an open or slightly ajar position, or vice versa. Within the scope of the invention, a door drive can also be understood to be a door opener (also called a "presenter") that merely moves the door into a slightly ajar position. The slightly ajar position allows the user to grasp the door and / or the operating unit from behind and then open it.

[0043] It is also conceivable that at least one sensor is designed as a capacitive sensor, an inductive sensor, or a microswitch. Capacitive sensors enable signal generation and thus electrical actuation simply through proximity and / or contact. In particular, the sensor can be designed as a capacitive metal-over-capacitor sensor. This sensor essentially comprises three components: a sensor electrode on a circuit board, a spacer, and a conductive metal surface as the target object. An electric field forms between the sensor electrode and the metal surface, similar to that of a capacitor. The capacitance of this system is continuously measured. When pressure is applied to the metal surface, it deforms slightly and moves closer to the sensor electrode. This changes the capacitance of the system, which can then be detected.As soon as a user touches the actuator, the sensor's capacitance changes, and the vehicle could interpret this as a request to unlock and / or open the lock. Metal-over-cap sensors offer several advantages for use in the actuator section, particularly the actuator unit. Their robustness is one advantage, as the metal surface protects the actual sensor. (HU49821 12.11.2024 ßols & Vogel)

[0044] It protects against environmental influences such as moisture and dirt. Furthermore, the integrated design allows the sensor to be invisibly installed behind a surface, offering aesthetic advantages. The sensor's reliability is another benefit, as it functions flawlessly even when wet or when the user is wearing gloves.

[0045] It is also conceivable that multiple sensors are present, including capacitive and / or inductive sensors and / or microswitches. An inductive sensor utilizes the principle of electromagnetic induction to detect metallic objects or changes in the electromagnetic field. The inductive sensor detects even the slightest movements of metal objects within its detection range. For example, the user exerts a (minimal) force on an actuating element, particularly the actuator, in which a metal object is located. This metal object can be a thin film, a sheet of metal, or metal particles embedded in plastic. The force applied by the user causes deformation, and the sensor can detect the relative movement between the metal and the sensor. It is also conceivable that the sensor moves closer to the metal object. The signal can then be used to automatically unlock and / or open the locking system.A microswitch is particularly cost-effective to implement. Preferably, the sensor unit comprises an electronic component carrier (ECT / PCB(A)). At least one sensor is arranged on the electronic component carrier. In the case of an inductive sensor, additional components for detecting incorrect activation may also be present. For example, it is conceivable that several coils are arranged at intervals from one another on the ECT or PCB.

[0046] Within the scope of the invention, it is optionally possible to provide at least one force sensor, wherein the force sensor detects a force acting on the actuating section, and wherein the force sensor is particularly designed as a piezoelectric sensor and / or a strain gauge. The use of a force sensor offers the advantage that actual actuation of the actuating unit of the actuator by a user can be detected more reliably. Effects on the actuator resulting from external environmental influences can be more reliably distinguished from actual user actions by the additional use of a force sensor. Therefore, the risk of false detections of user actions on the actuator is reduced by the additional use of at least one force sensor. The use of a force sensor has proven to be effective. HU49821 12.11.2024 ßols & Vogel

[0047] especially in combination with a touch-sensitive actuating element, it has proven to be particularly advantageous.

[0048] Furthermore, the invention may include at least one proximity sensor, which detects a user's approach to the cover device, and in particular, the at least one proximity sensor is designed as a capacitive sensor. Detecting a user's approach can, for example, trigger an authorization check to determine whether the user is authorized to access the vehicle. Additional sensors or communication interfaces can be used to query authorization during the authorization request. In particular, the authorization request can verify whether the user is carrying an ID transmitter and whether this ID transmitter authorizes the user to access the vehicle.The ID transmitter can preferably be designed as a car key or a mobile device, in particular a smartphone or a tablet.

[0049] Depending on the outcome of the authorization request, the power supply to at least the actuating unit, the actuating electronics, and / or the force sensor can preferably be activated, particularly via at least one, preferably electrical, switching element. In other words, it can preferably be provided that at least the actuating unit, the actuating electronics, and / or the force sensor are only active when user authorization to access the vehicle has been established. This can support energy-efficient operation of the vehicle. Additionally or alternatively, at least one communication interface, in particular a BLE interface, can be used to detect the approach of a user or an ID transmitter carried by the user.Thus, by establishing a communication connection to the ID provider, it can be inferred that the user is approaching the ID provider.

[0050] With regard to the present invention, it is conceivable that at least one communication interface is provided, wherein a communication connection to at least one ID transmitter can be established via the communication interface, and wherein the at least one communication interface is configured as an NFC interface and / or Bluetooth interface, in particular a BLE interface. The ID transmitter can preferably be HU49821 12.11.2024 ßols & Vogel

[0051] be designed as a car key or a mobile device, especially a smartphone or a tablet.

[0052] At least one communication interface, in particular a BLE interface, can preferably be configured or used to detect the approach of an ID transmitter to the vehicle. Thus, when an ID transmitter approaches, a communication link can be established between the BLE interface and the ID transmitter as soon as the ID transmitter is within range of the BLE interface. Once approach is detected, an authorization check can be performed and / or the ID transmitter can be detected or located, preferably via at least one environmental sensor, in particular at least one UWB sensor. From this, a user's access request to the vehicle can be derived, and if necessary, the power supply to at least one actuating element and / or triggering device and / or force sensor can be activated.

[0053] At least one NFC interface can be configured as an active NFC interface. In other words, the NFC interface can be configured to transfer power to a receiver, specifically so that the receiver can then transmit information to the NFC interface. This offers the advantage that a user with a valid ID transmitter can gain access to the vehicle even if the ID transmitter's power supply is depleted. Specifically, the ID transmitter can have a passive NFC interface for this purpose. This has proven particularly advantageous when a mobile device is used as the ID transmitter. The existing recessed handle can then serve as a receptacle for the ID transmitter, especially the mobile device, to facilitate charging.

[0054] Additionally or alternatively, at least one NFC interface can be configured as a passive NFC interface. In other words, the NFC interface can be configured to receive energy, particularly from a transmitter (e.g., an ID transmitter). This energy can be used, for example, to initiate a state change at at least one locking device of the vehicle or vehicle door. This offers the advantage that a user with a valid ID transmitter can gain access to the vehicle even when the vehicle's power supply is depleted. Specifically, the ID transmitter can have an active NFC interface for this purpose. HU49821 12.11.2024 ßols & Vogel

[0055] Furthermore, it is conceivable that at least one environmental sensor is provided, wherein the environmental sensor can detect objects in the external environment of the cover device, and wherein, in particular, the at least one environmental sensor is designed as a UWB unit and / or as a radar unit. Additionally or alternatively, at least one environmental sensor can be designed as a LIDAR sensor (Light Detection and Ranging) and / or as an image sensor, in particular a camera. The detection of an object in the environment of the cover device can, in particular, be the detection of a potential obstacle with regard to the opening or closing of the vehicle door and / or the, at least partially, autonomous operation of the vehicle. Thus, a user of the vehicle can be alerted to the presence of any obstacles, or an automatic opening or closing process can be prevented or interrupted if an obstacle has been detected.Additionally or alternatively, the detection of an object in the external environment can be the detection and / or location of an ID transmitter. Preferably, at least one UWB sensor can be used to detect or locate an ID transmitter in the external environment of the vehicle.

[0056] Within the scope of the invention, it can be advantageous to provide at least one lighting unit, wherein at least the handle recess and / or an area in front of the vehicle door can be illuminated by means of the lighting unit. Preferably, at least the handle recess or the operating unit and / or an area in front of the vehicle can be illuminated, at least partially, by the lighting unit. For this purpose, the lighting unit can preferably comprise at least one light source or a plurality of light sources. The light sources can be arranged at different positions on the cover device. In particular, at least one light source can be designed as an LED (Light-Emitting Diode). The use of a lighting unit results in increased user comfort.In particular, the user's attention can be actively drawn to the respective functions of the cover device and any obstructions in the area in front of the vehicle by appropriate lighting. The area in front of the vehicle is defined as the ground area located in front of a vehicle door when the cover device is used as intended.

[0057] Within the scope of the invention, it is conceivable that at least one status indicator is provided, wherein at least one status of the locking device and / or HU49821 12.11.2024 ßols & Vogel is indicated by means of the status indicator.

[0058] Authentication can be visualized. In particular, the actuator and / or the base unit can be equipped with an integrated status indicator or display that shows information, especially in real time, about the status of the locking device, the door drive, or a completed authentication. This status indicator is embedded in the actuator and / or the base unit so that it is visible and easily readable for the user without compromising the design. The display is typically implemented as an LED matrix or as a small, high-resolution display, which is protected from external influences by a water- and dirt-resistant cover and ensures long-term functionality.

[0059] Integrating this display allows for the direct transmission of information such as the door's locking status, the activity of the door drive, or the progress and success of an authentication process. For example, the status indicator could use a specific color scheme or symbols to show whether the door is unlocked or locked, whether an electronic drive has initiated the door opening, or whether the user's access request has been successfully confirmed by an authentication system such as a key or biometric verification. This information is particularly important for vehicles with keyless entry or automated door drives, as it allows the user to see at a glance whether the door mechanism is functioning correctly and whether access to the vehicle is permitted.

[0060] To ensure the display remains easily readable even under varying lighting conditions, adaptive brightness control can be used, adjusting to the ambient conditions. The status display thus provides a user-friendly and immediate source of information, enhancing the system's ease of use and safety.

[0061] Within the scope of the invention, it may be provided that the actuating section and / or the grip recess has at least a partially structured or coated surface. The coating may preferably be an anti-slip coating, in particular a rubber coating. This prevents the user from slipping during operation. The coated surface may preferably be an inner surface of the grip recess or the actuating unit facing the vehicle door or the vehicle. This information refers to HU49821 12.11.2024 ßols & Vogel

[0062] for the intended use of the cover device on a vehicle door or vehicle. This results in convenient access to and operation of the operating unit for a user.

[0063] It is also conceivable that the actuating section has a cover element, at least partially, which extends from the base body and preferably covers an extended area of ​​the engagement recess. The cover element preferably forms an extension of the actuating unit. This means that the actuating unit has a larger surface area, allowing a larger area of ​​the engagement recess to be covered. The cover element can preferably be designed as a strip. The cover element can be integral with the cover device, particularly the actuating unit, or it can be a separate element attached to the actuating unit. Preferably, the cover element can be visually distinct from the actuating unit. This makes the grip area easier for the user to identify.Preferably, the cover element is arranged flush with the adjacent area of ​​the door's outer skin during installation. This allows the cover element to integrate seamlessly into the door's aesthetically pleasing appearance, particularly in the handle area. It is also conceivable that the cover element is movably mounted or arranged on the cover device, at least in certain sections, or that it is at least partially flexible. This allows for a tactilely advantageous user experience when applying a pulling force to the cover element to open the door and / or unlock and / or disengage the locking mechanism.

[0064] It is also conceivable that at least the actuation electronics are at least partially arranged within the cover element. The cover element thus serves as a casing that protects the electronic components against moisture, dust, and unwanted mechanical influences. The actuation electronics embedded in the cover element comprise a multitude of components, particularly those used for controlling and operating the locking system and / or a door drive, including sensors and / or a control unit. The cover element is therefore designed to provide space for these electronic components while simultaneously ensuring that signal transmission is not impaired. Preferably, the cover element is designed so that sensors can react directly to touch or proximity through the outer wall, so that HU49821 12.11.2024 ßols & Vogel

[0065] The user can activate the locking system via touch gestures or a proximity sensor. The cover element can be equipped with a special conductive or capacitive surface that allows the electronic signals to pass through while simultaneously providing mechanical protection. For optimal attachment and integration into the track, the cover element can be form-fittingly inserted into the cover device, particularly the actuator, so that it is flush and blends seamlessly into the door design. Mechanically, it is preferably anchored in such a way that the electronics are protected against vibrations and shocks without impairing the sensitivity of the actuator electronics.

[0066] According to a second aspect, the present invention further relates to a motor vehicle door for a motor vehicle, comprising at least one locking device and at least one cover device according to the invention, wherein a window recess of the motor vehicle door is at least partially covered by the cover device and wherein the actuating unit is operatively connected with the locking device in such a way that a change of state at the locking device can be triggered by actuating the actuating unit by a user.

[0067] This results in the same advantages with regard to a motor vehicle door according to the invention as have already been described with regard to a cover device according to the invention.

[0068] The motor vehicle door can preferably be designed as a side door, specifically a front or rear passenger door, but within the spirit and scope of the present invention any vehicle door, including swing doors or tailgates, bonnets, side sliding doors, tailgates, rear doors, gullwing doors or the like, can be included.

[0069] It is advantageously conceivable that at least one door drive is provided for the motor vehicle door, wherein the motor vehicle door can be moved between a closed position and an open position by means of the door drive, wherein the actuating unit of the cover device is operatively connected to the door drive in such a way that an actuation by the user causes a movement of the motor vehicle door from the closed position to the open position or HU49821 12.11.2024 ßols & Vogel

[0070] It can be triggered in reverse. This results in a particularly high level of user-friendliness.

[0071] According to a third aspect, the present invention further relates to a motor vehicle comprising at least one motor vehicle door according to the invention.

[0080] Figure 1 shows a motor vehicle 300 with a motor vehicle door 100, the motor vehicle door 100 being equipped with a cover device 10. The cover device 10 is designed as a cover for a window channel of the motor vehicle door 100 and is arranged in the area of ​​the window. Such cover devices 10 serve as a seal between the window pane and the body or the door panel and / or as a decorative or design element. The cover device 10 extends in particular along the window between the A- and B-pillars of the motor vehicle door 100.

[0081] An actuating unit 20 is arranged on the cover device 10 according to the invention. In the illustrated embodiment, and preferably in the area of ​​the B-pillar, the actuating unit 20 is arranged. The actuating unit 20 has a mechanical connection in the form of a connecting element 31 and / or an electrical connection (e.g., in the form of an electrical cable) to a locking device 130. The locking device 130 is preferably designed as an electrically actuated side door locking device (e-latch). A connecting element 31 is provided for the mechanical connection to the locking device 130, which interacts with an actuating mechanism 30, so that mechanical actuation, in particular opening of the locking device 130 or the locking mechanism of the locking device 130, is possible.The connecting element 31 can preferably be designed as a Bowden cable or a rope and has a connection to a lever, in particular an external actuation, internal actuation, or release lever of the locking device 130. The locking device 130 can be mechanically opened / unlocked via this connection. This means that the locking mechanism of the locking device 130 can be opened by means of the connecting element 31, so that the vehicle door 100 is released from a lock holder (lock bolt) arranged on the vehicle 300 and can be moved into an open position.

[0082] Figure 1 further shows a frontal area 310 of the motor vehicle 300 or the motor vehicle door 100. The movement range 320 of the motor vehicle door 100 is also shown. It can be seen how the user 200 uses their hand 210 to actuate the operating unit 20 on the cover device 10 in order to open the door 100 (motor vehicle door 310). The cover device 10 comprises a structural base body 11 that partially covers and protects the window recess 110 and the engagement recess 120. The base body 11 of the cover device 10 is designed such that it forms a HU49821 12.11.2024 ßols & Vogel

[0083] The special actuation section 11.1 includes an ergonomically shaped grip recess 11.2, which is adapted to the contour and grip position of the user's hand 210. This grip recess 11.2 is located in the base body 11 and opens downwards towards the road, providing optimal protection against environmental influences such as dirt or moisture while simultaneously facilitating access for the user's hand 210.

[0084] The actuating section 11.1 of the cover device 10 is designed such that the user's hand 210 occupies a natural gripping position, thereby activating the actuating unit 20. The actuating unit 20 is in direct operative communication with the locking device 130 of the door 100. Through an interaction, such as pushing or pulling on the actuating unit 20, the user 200 can change the state of the locking device 130, for example, unlocking and opening the door. Fig. 1 shows the moment when the user's hand 210 touches the actuating unit 20 to gain access to the vehicle 300.

[0085] Figure 1 shows the area 310 in front of the motor vehicle 300 or the motor vehicle door 100. The movement area 320 of the motor vehicle door 100 is also shown. An environmental sensor 80 can be provided to monitor the movement area 320 and / or the area 310 so that obstacles can be detected. Furthermore, a lighting unit 90 can be provided to illuminate the area 310 and / or the movement area 320.

[0086] Fig. 2 shows a section of a motor vehicle door 100 according to the invention with a possible embodiment of a cover device 10 according to the invention. The cover device 10 has a base body 11 that extends along the window recess 110 and covers it. The base body 11 has an actuating section 11.1 in which the actuating unit 20 is arranged. Below the actuating unit 20 and in the area of ​​the actuating section 11.1, the engagement recess 120 is formed on the outer door skin. The engagement recess 120 is arranged and designed such that a user 200 can reach into the actuating section 11.1 from below with their hand 210 and touch and / or grasp the actuating unit 20 to actuate it. HU49821 12.11.2024 ßols & Vogel

[0087] One component of the actuation unit 20 is the actuation electronics 40, which functions as a control and processing module. This electronics unit receives signals from the various sensors 42, 50, 60 and evaluates them in real time to execute the desired actions, such as unlocking or locking the door. A sensor unit 41 is integrated within the actuation electronics unit 40, which comprises several sensors 42, 50, 60 and forwards their data to the electronics unit.

[0088] The sensor unit 41 includes various sensors that perform specific tasks. For example, sensor 42 is responsible for basic touch detection and ensures that the locking device 130 is only actuated when there is clear contact with the user's hand 210. At least one sensor 42 can be designed as a capacitive sensor 42, an inductive sensor 42, or a microswitch, allowing for flexible touch detection and activation of the locking device using different sensor technologies. Additionally, at least one force sensor 50 is provided, which detects the force acting on the actuating section 11.1 and thus on the actuating unit 20. In particular, the force sensor 50 is designed as a piezoelectric sensor and / or a strain gauge, enabling precise measurement of even the smallest pressure changes.This configuration allows for targeted detection of the force applied by the user, so that the actuation unit 20 is only activated when pressure is consciously applied, thus preventing incorrect activations.

[0089] The sensor unit 41 also has at least one proximity sensor 60 that detects the approach of the user 200 to the cover device 10. This proximity sensor 60 is specifically designed as a capacitive sensor 42, which allows for precise and contactless detection of the approach. This detection pre-activates the actuating unit 20 and prepares it for possible interaction, so that the user can operate the door 100 seamlessly and without delay. The proximity sensor 60 is located in the cover device 10 and detects a hand or other body parts even before they physically touch the actuating section 11.1. In the embodiment shown in Fig. 2, the other sensors are located in the cover element 12. As shown, the cover element 12 extends away from the cover device 10 and thus covers part of the grip recess 120 on the door 100. The grip recess 11.The area on actuating unit 20 is thereby enlarged. HU49821 12.11.2024 ßols & Vogel.

[0090] To control the locking device 130 in conjunction with authentication, the actuating unit 20 has a communication interface 70 that enables wireless communication with an ID transmitter. This interface 70 (communication interface 70) is preferably implemented as an NFC interface and / or as a Bluetooth interface, in particular as BLE (Bluetooth Low Energy). The NFC interface allows for secure, short-range authentication processes, for example, when the user 200 is brought near the cover device 10 with an NFC-enabled device or key. The BLE interface enables extended communication and authentication with mobile devices over a greater distance. Both interfaces work closely with the actuating electronics 40 to identify the user 200 and grant appropriately authorized access to the locking device 130.

[0091] Another component of the actuation unit 20 is the environmental sensor 80, which serves to detect objects in the external environment of the cover device 10. This environmental sensor 80 can be implemented as a UWB (Ultra-Wideband) unit or as a radar unit. UWB enables precise distance measurements and the detection of movements, which is particularly useful for detecting an approaching user 200 or potential obstacles. The radar unit provides similarly precise environmental sensing and can be used in combination with the actuation electronics 40 to automatically unlock the door in certain situations, trigger a safety function, or open and close the door.

[0092] In addition to the sensor equipment, the operating unit 20 can be equipped with a lighting unit 90 that specifically illuminates the handle recess 11.2 and / or the area 310 in front of the door. This lighting unit 90 provides the user 200 with clear visual orientation, especially in poor lighting conditions, and highlights the operating area of ​​the door. The status indicator 91 uses different colors, symbols, or lighting patterns to clearly inform the user 200 whether the door is locked or unlocked and whether authentication was successful. This combination of lighting and status indicator 91 ensures user-friendly and intuitive operation, where the status of the vehicle door 100 is always clearly visible. HU49821 12.11.2024 ßols & Vogel

[0093] Even though in Fig. 2 the sensors and / or communication interfaces 70 and / or lighting unit 90 and / or status indicator 91 are arranged in the cover element 12, it is conceivable according to the invention that all or some of the aforementioned components are arranged in the cover device 10 or the base body 11.

[0094] Figure 3 shows a cross-section of the embodiment of the cover device 10 shown in Figure 2. It is particularly evident how the cover element 12 is designed and arranged on the cover device 10, especially on the actuating unit 20. The cover element 12 provides additional protection and covers a further area of ​​the engagement recess 120. It also provides better protection for the handle recess 11.2. The handle recess 11.2 is located on the actuating unit 20 of the cover device 10 and is formed, in particular, by the shape of the cover device 10 in the actuating section 11.1. The cover element 12 is flush with the adjacent outer surface of the door 100, thus creating an aesthetically pleasing appearance. It is also shown that at least one sensor, here by way of example a proximity sensor 60, is arranged in the base body 11 of the cover device 10.Another sensor, here by way of example a force sensor 50 of the sensor unit 41, is arranged in the cover element 12. The cover device 10 also has fastening means 13 which are provided for easy mounting on / in the window recess 110. By means of the fastening means 13, the cover device 10 and in particular the actuating unit 20 can be connected to the window recess 110 and thus to the vehicle door 100.

[0095] Fig. 4 shows an embodiment of the cover device 10 according to the invention, wherein the actuating unit 20 does not have a cover element 12. This allows for an even more minimalist appearance, in which only an engagement recess 120 indicates an actuating section 11.1. The cover device 10 has an actuating unit 20 in the actuating section 11.1. This actuating unit 20 is, in this case, and preferably, formed separately from the base body 11. This means that the actuating unit 20 and the base body 11 form two components. In this embodiment as well, the engagement recess 120 is partially covered by the cover device 10 and thus also by the actuating unit 20, or forms a kind of roof. Dirt and water from the windows can therefore not enter the engagement area and thus also not enter the actuating area or the handle recess 11.2. HU49821 November 12, 2024 ßols & Vogel

[0096] In this embodiment, the cover device 10 also includes actuation electronics 40 with a sensor unit 41 and at least one sensor 42. Furthermore, the actuation unit 20 comprises a status indicator 91 and a communication interface 70.

[0097] Figure 5 shows a cross-section of the cover device 10 according to the invention as shown in Figure 4. The actuating unit 20, which is arranged in the area of ​​the engagement recess 120 and covers or roofs it at least partially, is particularly visible. The cover device 10 also has fastening means 13, which are provided for easy mounting on / in the window recess 110. The cover device 10, and in particular the actuating unit 20, can be connected to the window recess 110 and thus to the vehicle door 100 by means of the fastening means 13.

[0098] It is further evident that the design and shape of the cover device in the actuating section 11.1, and thus on the actuating unit 20, creates a grip recess 11.2 into which a user can insert their hand or fingers to perform an actuation. For improved tactile feedback, the grip recess 11.2 has a structured or coated surface 11.3. The coating or structure is preferably an anti-slip coating, in particular a rubber coating. This prevents the user from slipping during operation. As described in connection with Fig. 4, the actuating unit 20 has at least one sensor unit 41 with at least one sensor 42. The sensor 42 is arranged on the base body 11 of the actuating unit 20 in such a way that a user's hand or fingers are not detected when the sensor is inserted into the grip recess 11.2 or an approach to the actuating unit 20 triggers a signal.

[0099] In addition to sensor 42, a proximity sensor 60 is arranged in the engagement recess 120 and is designed such that a user's hand can be detected when inserted into the engagement recess 120. Furthermore, the cover device 10 on the actuating unit 20 has a communication interface 70, which is designed, for example, as an NFC and / or Bluetooth interface and is intended for communication with an ID transmitter.
