[0005] Extendable handle assembly for a motor vehicle door

[0006] Description

[0007] The invention relates to a handle arrangement with the features of the first independent claim, a cover device with the features of the second independent claim, and a motor vehicle door with the features of the third independent claim.

[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 WO 2004 / 079137 A1, a handle arrangement is known solely for emergency use, enabling purely mechanical operation of the locking mechanism. For this purpose, a handle can be pulled out from within a cover plate for the door. This handle is connected to the locking mechanism via a Bowden cable, thus allowing mechanical operation of the locking mechanism. However, the ergonomics are disadvantageous, as the user has to remove the handle from the cover plate. Another variant is designed as a folding mechanism with a complex hinge. ßols & Vogel

[0010] Handle arrangements with a minimalist design and electronic actuation of the locking device are also known from FR 3096713 A1 and DE 102019117779 A1. A disadvantage of these disclosed handle arrangements is the always open engagement area, which is susceptible to dirt and accidental operation, particularly in car washes. Furthermore, these disclosed handle arrangements always require a recess in the vehicle body, which entails additional design disadvantages and increases susceptibility to external environmental influences.

[0011] 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 the invention to provide a handle arrangement, a cover device, and a motor vehicle door that meets the safety requirements and at the same time offers better protection against external environmental influences.

[0012] The foregoing problem is solved by a handle arrangement having the features of the first independent claim, by a cover device having the features of the second independent claim, and by a motor vehicle door having the features of the third independent claim. 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 handle arrangement according to the invention naturally also apply in connection with the cover device and / or the motor vehicle door according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention always includes, or allows for, reciprocal reference.

[0013] The invention provides a handle arrangement for operating a locking device of a motor vehicle door, wherein the handle arrangement can be arranged on a cover device of the motor vehicle door, comprising at least one handle body, wherein the handle body can be moved into at least a rest position and an operating position, wherein the handle body can be arranged flush with the cover device in the rest position and forms an engagement area in the operating position, further comprising a sensor unit, in particular arranged in the handle body, for recognizing a user. According to the invention, it is provided that the handle body can be extended and / or retracted from the rest position.

[0014] The operating position or vice versa is designed. The handle arrangement according to the invention makes it possible to provide an opening aid for the door that is ergonomically advantageous and at the same time less susceptible to environmental influences. The cover device can in particular be a channel strip or part of a channel strip (in the area of ​​the transition between the door panel and the window of the door). Such cover devices or channel strips are arranged on the motor vehicle door in the area of ​​the window panes. The cover devices serve in particular to protect the transition between the body, the door and the window from moisture, dirt and the like, and at the same time as a design element.Due to its placement on the door, intuitive operation by the user is possible, and design specifications can be easily implemented because the vehicle body (including the door panel) does not require an additional recess for a retractable handle. Within the scope of the invention, the design on a window channel can also include the handle assembly being located directly below the window channel.

[0015] 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, loading ramps, rear doors, gull-wing doors or the like, can be included.

[0016] The handle body is the part of the handle assembly that a user grasps (with their hand) when they wish to act upon the door or open it. The handle body is preferably an essentially elongated body that is also recognizable to the user as a handle. The handle body is movable, in particular extendable and / or retractable. It can be moved externally by a generated force and / or by a user. Thus, the handle body is designed so that a user can exert force on the handle and therefore on the door, for example, to move it into the open position. For this purpose, the handle body can be moved from a rest position to an operating position. To allow a user to grasp the handle comfortably, especially with their hand, an engagement area is provided in the operating position.The area of ​​intervention can be a gap into which a user can, for example, place one or more fingers, especially to reach behind. Thus, force can be applied to the ßols & Vogel.

[0017] Handle body data is transmitted to enable the door to be opened and / or to generate sensor signals.

[0018] Furthermore, a sensor unit is provided. The sensor unit is preferably arranged in or on the handle body so that a user and / or at least a user's hand can be detected or recognized. However, it is alternatively or additionally conceivable that the sensor unit is arranged adjacent to the handle body.

[0019] According to the invention, the handle body is designed to be extendable and / or retractable from the rest position to the operating position, or vice versa. This means that the handle body can be moved from the rest position to the operating position, in particular linearly. In the case of a linear movement, the handle body can, for example, be extended from the cover device. The handle body is therefore fundamentally designed to be displaceable or movable along an axis. Accordingly, the position of the handle body can be changed, at least partially. This allows the handle body, in its rest position, which is at least substantially flush with the cover device, to provide an engagement area for a user's hand as soon as the handle body has been extended.Extending the handle body into the operating position creates an engagement area on the handle assembly, located between the cover device and the handle body. This engagement area is dimensioned such that the handle body is essentially parallel to the cover device in the operating position.

[0020] Preferably, the handle body is movable away from the vehicle door, i.e., towards the user, or retractable towards the vehicle door and away from the user. This further improves ergonomics. The improved ergonomics are achieved in particular by creating an engagement area through the movement of the handle body, which has the same orientation as a conventional door handle. A user can therefore reach into the engagement area from above with their hand and operate the handle body and / or generate a sensor signal. This also enables the user to exert sufficient force on the door to open it, for example, after an accident, especially if the door is jammed or difficult to open. For this purpose, the handle body advantageously has a fixed end position in the operating position. ßols & Vogel

[0021] At the same time, the handle design can offer improved protection against environmental influences and accidental activation. In its resting position, the handle body is flush with the cover, thus protecting at least the engagement area from environmental influences and accidental activation, for example, in a car wash. Furthermore, it is conceivable that the handle body could also be tilted. In particular, it is conceivable that the handle body could be tilted at the end of its extension or retraction movement. This would allow the handle body to be tilted towards the user after extension, thus improving user ergonomics.

[0022] The design according to the invention thus makes it possible to provide a handle arrangement that is ergonomically advantageous and insensitive to environmental influences.

[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 therefore be opened even without mechanical external and / or internal operation. It is thus possible to dispense with mechanical internal and / or external door handles that are mechanically connected to the locking device.

[0024] Within the scope of the invention, it can be advantageous for the sensor unit to comprise 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 can be generated for the locking device. A user's access request can thus be recognized by means of the sensor. Subsequently, the locking device and / or a door control unit are activated, and the locking device is unlocked and / or opened or locked and / or closed. "Locking and unlocking" can be understood as the actuation of a central locking system, and "opening or locking" as the opening or locking of the lock mechanism. ßols & Vogel

[0025] The sensor unit is therefore designed to detect a user's approach to the handle and the associated access request. In particular, the sensor is designed to detect when the user touches the handle. The sensor and / or sensor unit can be located on the outside (facing away from the vehicle door) and / or inside (facing the vehicle door) of the handle. It is also conceivable that the sensor and / or sensor unit are located adjacent to the handle.

[0026] 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 handle and then open it.

[0027] Within the scope of the invention, it is conceivable that the at least one sensor is designed as a capacitive sensor, an inductive sensor, or a microswitch. Capacitive sensors allow signal generation, and thus electrical actuation, to be triggered simply by proximity and / or contact. In particular, the sensor can be designed as a capacitive metal-over-capacitor sensor. The sensor essentially comprises three components: a sensor electrode on a circuit board, a spacer layer, 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 handle body, 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 handle assembly, particularly the handle body. Their robustness is a benefit, as the metal surface protects the actual sensor from environmental influences such as moisture or dirt. Furthermore, the design integration allows the sensor to be invisibly installed behind a surface, offering aesthetic advantages. The sensor's reliability is a key factor for ßols & Vogel.

[0028] Another advantage is that it works perfectly even when wet or when the user is wearing gloves.

[0029] 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 a handle area, particularly the handle body, in which a metal object is located. The metal object can be a thin film, a sheet of metal, or metal particles embedded in plastic. The force exerted 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.

[0030] Within the scope of the invention, it may be provided that an actuating mechanism is provided for the handle body, wherein the handle body can be moved at least from the rest position to the operating position by means of the actuating mechanism.

[0031] It is also conceivable that the actuation mechanism automatically moves the handle body from the rest position to the operating position as soon as the sensor unit detects that a user is approaching the vehicle door and / or automatically moves the handle body from the operating position to the rest position as soon as the sensor unit detects that a user is moving away from the vehicle door. The actuation mechanism thus enables the handle body to be automatically extended into the operating position. The actuation mechanism can include a drive unit by means of which the handle body can be moved from the rest position to the operating position. Miniature drives are particularly suitable for extending or moving the handle body. ßols & Vogel

[0032] The actuation mechanism can preferably extend the handle body when a user approaches the vehicle and thus the handle assembly. This makes the handle body more visible and accessible to the user. Furthermore, it is conceivable that the actuation mechanism moves the handle body into the operating position as soon as a vehicle accident is detected.

[0033] The sensor unit or a separate control unit can be used to control the actuation mechanism. Furthermore, it is conceivable that the actuation mechanism, in particular a drive unit, is connected to a crash sensor of the vehicle, so that in the event of an accident the handle is moved into the operating position.

[0034] The actuation mechanism may also include a spring arrangement that moves the handle body from the rest position to the operating position by means of spring force.

[0035] It is also conceivable that an NFC interface and / or a Bluetooth interface are provided. Such near-field communication sensors can transmit electrical signals and electrical energy. In particular, the NFC interface can be used to control a central locking system (for locking and / or unlocking) or the operating mechanism, thereby moving the handle body into the operating or resting position. The NFC interface can communicate with an ID transmitter. For the purposes of this invention, an ID transmitter is understood to be at least a radio key, a key card, and / or a portable communication device, e.g., a smartphone.

[0036] The Bluetooth interface, especially Bluetooth Low Energy (BLE), is used for communication with an ID transmitter and thus for user authentication.

[0037] Within the scope of the invention, it is optionally possible for the NFC interface to be configured to transmit electrical energy to and / or receive it from an ID transmitter. Thus, it is possible for electrical energy to be transmitted from the ID transmitter to the handle assembly and / or to the locking device, or received by at least one of the two. Consequently, an ID transmitter can be used to control the ßols & Vogel

[0038] The handle assembly, in particular the sensor unit and / or operating mechanism (drive of the operating mechanism), the locking device, and / or a door drive, must be supplied with electrical energy. This is particularly relevant for safety in cases where the vehicle's electrical system has failed and the aforementioned components can no longer be supplied with power. Especially with electrically operated locking devices, it is necessary to supply them with electrical energy so that opening or unlocking is possible. Without a mechanical internal or external actuator, the lock cannot be opened. Electrically operated locks are typically equipped with capacitors to provide electrical energy for a certain period in the event of a power failure.However, these capacitors and the necessary electronics are expensive and / or only provide sufficient energy for a relatively short period. If an NFC interface according to the invention makes it possible to supply electrical energy from outside the vehicle, the aforementioned problem can be solved.

[0039] Furthermore, it is conceivable that energy could be transferred from the vehicle to the ID transmitter via the NFC interface. This would allow the ID transmitter to be charged, enabling communication with the sensor unit, a door control unit, or a vehicle control unit for unlocking and / or opening signals and / or authentication signals.

[0040] Furthermore, the invention may include a UWB unit or a radar unit, wherein the UWB unit or the radar unit is specifically configured to detect objects, particularly in a movement area and / or in the vicinity of the handle assembly of the vehicle door. Ultra-wideband (UWB) is a short-range RF technology for wireless communication that can be used to determine the location of people and / or objects / obstacles with unsurpassed precision. Like other communication protocols, e.g., Bluetooth and Wi-Fi, UWB can be used to transmit data between devices via radio waves. This is done with short pulses in the nanosecond range over an "ultra-wide" range of frequencies. UWB can determine the location so accurately because it uses distance-based measurement via the time-of-flight (ToF) method to determine the location.

[0041] calculated based on the time it takes for radio pulses to travel from one device to another.

[0042] The UWB unit can be used for obstacle detection, particularly for electrically operated doors. Furthermore, it can also detect people in the vicinity of the door who wish to access the vehicle. Thus, the UWB unit can also be used to initiate identification and / or to move the handle from its resting position to the operating position via the actuation mechanism. Alternatively or additionally, the UWB unit can be used to locate an ID transmitter. Near Field Communication (NFC), Bluetooth Low Energy (BLE), and Ultra Wideband (UWB) complement each other as distinct technologies and demonstrate their strengths when approaching the vehicle. In particular, the UWB radio technology enables very precise time-of-flight measurement and therefore high location accuracy for vehicle access.In addition to point-to-point measurement, the UWB sensors also have the ability to process radar signals and thus detect people and their gestures and / or obstacles.

[0043] A radar unit acts as a sensor, using electromagnetic waves to detect objects near the door or those that might enter the door's opening area. By precisely detecting objects such as people or obstacles, the system can prevent potential collisions or damage by stopping or adjusting the door's movement. This increases safety when opening and closing the vehicle door, especially in tight parking spaces or situations with limited visibility. The radar unit operates reliably and is unaffected by external influences such as rain or darkness, ensuring continuous functionality.

[0044] With regard to the present invention, it is conceivable that the handle body includes a lighting unit, wherein at least the engagement area and / or a front area of ​​the vehicle door can be illuminated by means of the lighting unit. The lighting unit can be integrated into the handle body. The illumination makes it possible, in particular, to locate the handle body more easily and consequently also to identify the engagement area. It is conceivable that the lighting unit is connected to the sensor unit via a signal, so that the lighting unit can be activated and / or deactivated. Furthermore, it is conceivable that the lighting unit illuminates a front area of ​​the vehicle door in a known manner. ßols & Vogel

[0045] Furthermore, it is conceivable that an electronic unit is provided, wherein the electronic unit is arranged at a distance from or adjacent to the handle body, particularly in the cover device, and is electrically connected to the sensor unit. This allows the required installation space in the handle body to be reduced and sensitive components to be arranged in less stressed areas. In particular, this makes it possible to integrate only the electronic components involved in unlocking or opening the locking mechanism into the handle body. The remaining electronics are integrated into the electronic unit. The electronic unit can, for example, be arranged in a channel of the door.

[0046] Within the scope of the invention, it can be advantageous to provide a mechanical emergency opening mechanism, whereby the locking device can be mechanically unlocked and / or opened / unlocked by means of this emergency opening mechanism. In the event that the vehicle lacks electrical power to operate the locking device, safety regulations require a mechanical emergency opening mechanism to allow the locking device to be opened / unlocked. According to the invention, a mechanical emergency opening mechanism is proposed, which creates a mechanical connection between the handle assembly and the locking device. A user can thus, for example, still manually operate the locking device in the event of a crash or a loss of vehicle power. It is particularly intended that the emergency opening mechanism can only be activated after prior authentication or after a detected accident, so that misuse can be essentially prevented.Without authentication, the emergency release cannot be activated. It is conceivable that the NFC interface could be used for this purpose, allowing an ID provider to authenticate the user.

[0047] Within the scope of the invention, it is conceivable that the mechanical emergency opening includes a connecting element, in particular a cable or a Bowden cable, wherein the connecting element can be mechanically connected to or is connected to the locking device. Simple actuation of the connecting element, e.g., by pulling, thus enables simple mechanical actuation of the locking device. The connecting element can be connected directly or indirectly to the locking mechanism of the locking device. Preferably, the connecting element is connected to an internal or external actuation or a release lever of the locking device. By actuating the connecting element, e.g., by pulling, the locking mechanism is then opened / unlocked and the lock is released.

[0048] The vehicle door can be opened using the handle. Advantageously, the connecting element is designed as a cable or Bowden cable. This offers the advantage of a cost-effective connection element that can be flexibly positioned within the vehicle door. Furthermore, the connecting element can incorporate a pull tab. First responders approaching the vehicle can immediately identify the pull tab, which allows the door to be opened easily. The advantage of the pull tab: even with a distorted body as a result of an accident, the pull tab provides an excellent point of leverage and withstands high tensile forces. This allows both the locking mechanism to be opened and the door to be pulled into the open position.

[0049] Within the scope of the invention, it can be provided that the mechanical emergency release has a cover element that is detachable from the handle assembly, so that the connecting element can only be operated by a user after removing the cover element. If the main control unit in the car detects an accident, it sends a signal to the handle assembly. The system then opens the cover element and provides first responders with access to the connecting element, in particular a pull tab. Advantageously, the cover element is not visible or accessible during normal operation.

[0050] It is also conceivable that the mechanical emergency release is concealed by the handle body in the rest position and operable by a user in the operating position. This prevents misuse or at least makes it more difficult. The mechanical emergency release is therefore not visible or only difficult to access during normal operation.

[0051] It is also conceivable that the handle body incorporates a force sensor. A force sensor serves primarily to reduce false triggers or incorrect activations. To do this, the force sensor detects when a user activates the handle body and can thus distinguish, for example, whether a car wash has triggered a sensor. It can be particularly advantageous to use a combination of sensors. For instance, the force sensor can be used in addition to an inductive and / or capacitive sensor. Furthermore, a force sensor can also be used to provide pinch protection, preventing a user's finger from being trapped when the handle body is retracted. ßols & Vogel

[0052] Within the scope of the invention, it is optionally possible for the handle body to have a recess for the user's hand. The recess is preferably located on the side facing the vehicle door. A recess is understood to be, in particular, a concave geometry into which a user can place their hand or at least a finger. This allows the user to exert force on the handle body with particular reliability, while simultaneously enabling an ergonomically and haptically positive design. Furthermore, a recess protects the actuation area, i.e., the area in which at least part of the sensor unit is located, from environmental influences and accidental activation.

[0053] Furthermore, the invention may provide that the engagement recess has a structured and / or rubberized surface, at least in some sections. This design improves ergonomics and haptics. It also allows the user to feel where the actuation area is located. A structured surface can further reduce slippage.

[0054] With regard to the present invention, it is conceivable that the engagement area is dimensioned such that an ID transmitter can be arranged within it. Particularly in conjunction with an NFC and / or UWB interface, it is possible to transfer electrical energy and / or signals between an ID transmitter, especially a smartphone, and the handle assembly in a simple and reliable manner. As already described in connection with authentication and / or energy transfer in the event of a power failure and / or emergency operation, communication between the handle assembly and an ID transmitter is advantageous for reliable and secure operation.

[0055] The above problem is further solved by an inventive cover device for a motor vehicle door with a handle arrangement according to one of the preceding claims and the present description.

[0056] This results in the same advantages with regard to a cover device according to the invention as have already been described with regard to a handle arrangement according to the invention. The cover device can, in particular, be used as a cover device for a ßols & Vogel

[0057] The window channel strip may be formed or integrated into it. This design or decorative element is located on the vehicle door in the window area.

[0058] The above problem is further solved by a motor vehicle door according to the invention with a cover device, in particular according to claim 19, and at least one locking device arranged in the motor vehicle door, in particular an electrically actuated locking device and with a handle arrangement having the features according to one of claims 1 to 18.

[0059] This results in the same advantages for a motor vehicle door according to the invention as have already been described for a handle arrangement and / or a cover device according to the invention. The motor vehicle door can preferably be designed as a side door, specifically a front or rear passenger door; however, within the spirit and scope of the present invention, any vehicle door can be included, including swing doors or tailgates, hoods, sliding side doors, tailgates, rear doors, gullwing doors, or the like.

[0060] Further advantages, features, and details of the invention will become apparent from the following description, in which several exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination.

[0061] Fig. 1 schematically shows a motor vehicle with a motor vehicle door as well as a cover device and a handle arrangement according to the invention;

[0062] Fig. 2a schematically shows a possible embodiment of a cover device according to the invention with a handle arrangement in the rest position;

[0063] Fig. 2b schematically shows a possible embodiment of a cover device according to the invention with a handle arrangement in the operating position; ßols & Vogel

[0064] Fig. 3a schematically shows another possible embodiment of a cover device according to the invention with a handle arrangement in the operating position and

[0065] Fig. 3b schematically shows the embodiment of Fig. 3a from a different perspective.

[0066] The figures use identical reference numerals for the same technical features, even for different embodiments.

[0067] Figure 1 shows a motor vehicle 200 with a motor vehicle door 100, the motor vehicle door being equipped with a cover device 110. The cover device 110 is designed as a cover for a channel strip of the motor vehicle door 100 and is arranged in the area of ​​the window 150. Such cover devices 110 serve as a seal between the window pane 150 and the body or door panel 160 and / or as a decorative or design element. The cover device 110 extends in particular below and along the window 150 between the A- and B-pillars of the motor vehicle door 100.

[0068] The motor vehicle 200 is shown in an accident situation, with the user 210 (first responder) using the handle arrangement according to the invention to move the motor vehicle door 100 into the open position. For this purpose, it is preferably provided that, after a crash signal from the vehicle 200, the handle arrangement 10 moves into the operating position, so that the user 210 can grasp the handle accordingly.

[0069] A handle assembly 10 according to the invention is arranged on the cover device 110. In the illustrated embodiment, and preferably in the area of ​​the B-pillar, the handle assembly 10 is arranged. The handle assembly 10 has a mechanical connection in the form of a connecting element 17.1 and / or an electrical connection (in the form of an electrical cable) to a locking device 20. The locking device 20 is preferably designed as an electrically operated side door locking device (e-latch). A connecting element 17.1 is provided for the mechanical connection to the locking device (20). The connecting element 17.1 can preferably be designed as a Bowden cable or as a rope and has a connection to a lever, in particular an external actuation, internal actuation, or release lever of the locking device 20. The locking device 20 can be mechanically opened / unlocked via this connection. [The last sentence appears to be a fragment and is omitted.]

[0070] This means that the locking mechanism of the locking device 20 can be opened by means of the connecting element, so that the motor vehicle door 100 is released from a lock holder (lock bar) arranged on the motor vehicle 200 and can be moved into an open position.

[0071] Furthermore, Fig. 1 shows a foreground 120 of the motor vehicle 200 or the motor vehicle door 100. In addition, the movement area 130 of the motor vehicle door 200 is shown.

[0072] Fig. 2a shows a section of a motor vehicle door 100 with a section of the cover device 110 according to the invention and a handle arrangement 10 according to the invention in the rest position I. As explained above, the cover device 110 is arranged in the area of ​​the window 150 and extends in the longitudinal direction of the vehicle.

[0073] The handle assembly 10 comprises a handle body 11, which is shown in its rest position I, in which the handle body 11 is substantially flush with the cover device 110. Thus, only a small gap exists between the cover device 110 and the handle body 11. A lighting unit 15 is arranged on the handle body 11. The lighting unit 15 can make the handle body 11 more visible / recognizable to a user. Furthermore, the lighting unit 15 can be designed to illuminate a foreground and / or a movement area of ​​the vehicle door 100 and / or an engagement area of ​​the handle assembly 10 or the handle body 11. The handle assembly 10 also includes a sensor unit 13. In the illustrated embodiment, the sensor unit 13 has two sensors 13.1, each of which can be designed as a capacitive or inductive sensor.Furthermore, the sensor unit 13 includes three NFC interfaces 13.2. One NFC interface 13.2 is located adjacent to the handle body 11 and another NFC interface 13.2 is located above the handle body 11.

[0074] In particular, the NFC interface 13.2 can be used to control a central locking mechanism or the actuating mechanism, thereby moving the handle body 11 into the operating or rest position. The NFC interface 13.2 can communicate with an ID transmitter. Within the scope of the invention, an ID transmitter is defined as ßols & Vogel.

[0075] at least a radio key, a key card and / or a portable communication device, e.g. a smartphone, must be understood.

[0076] The sensor unit 13 is designed to detect a user's approach to the handle body 11 and the associated access request. In particular, the sensor unit 13, e.g., sensor 13.1, is designed to detect a user touching the handle body 11.

[0077] In the illustrated embodiment, it can be seen that, advantageously, the handle body 11 comprises only the lighting unit 15, while the remaining electronics, in particular the electronic unit 16 and at least part of the sensor unit 13, are arranged in the cover device 110. It is also conceivable that the electronic unit 16 is arranged on a door module. This has the advantage that the sensitive components can be better protected from environmental influences and / or stresses.

[0078] Figure 2b shows essentially the same features as Figure 2a. However, in Figure 2b, the handle body 11 is in operating position II and thus forms an engagement area 12. As can be seen, the handle body 11 is extended and consequently moved / shifted towards a user. In order for a user to be able to grasp behind the handle body, the handle body is moved towards the user and thus away from the vehicle. In the operating position II then reached, the handle body 11 is arranged essentially parallel to the cover device 110. The engagement area 12 thus formed is therefore dimensioned such that a user's hand can grasp behind the handle body 11.

[0079] Figure 2b further shows that another sensor, in particular an NFC interface 13.2, is arranged in the area of ​​the handle body 11, but concealed by it in the rest position. The NFC interface 13.2 can be used in particular for communication with an ID transmitter 140, preferably a smartphone.

[0080] Such near-field communication sensors can transmit electrical signals and electrical energy. In particular, the NFC interface 13.2 can be used to control the actuation mechanism and thus move the handle body 11 into operating position II. (Sols & Vogel)

[0081] or to move to the rest position. The N FC interface 13.2 can communicate with an ID encoder 140.

[0082] It is preferably possible for the N FC interface 13.2 to be configured to transmit electrical energy to and / or receive it from the ID transmitter 140. Thus, it is possible for electrical energy to be transmitted from the ID transmitter 140 to the handle assembly 10 and / or to the locking device, or to be received by at least one of them. Consequently, an ID transmitter 140 can be used to supply the handle assembly 10, in particular the sensor unit 13 and / or the actuating mechanism (or its drive), the locking device, and / or a door drive with electrical energy. This is particularly relevant for safety in cases where the vehicle's electrical system has failed and the aforementioned components can no longer be supplied with electrical energy.

[0083] Especially with electrically operated locking devices, it is necessary to supply them with electrical energy so that opening or unlocking is possible. Without a mechanical internal or external actuator, the lock cannot be opened. Electrically operated locks typically have capacitors installed to provide electrical energy for a certain period in case of a power failure. However, these capacitors and the necessary electronics are expensive and / or only supply sufficient energy for a relatively short time. If an NFC interface 13.2 according to the invention enables the supply of electrical energy from outside the vehicle, the aforementioned problem can be solved.

[0084] Furthermore, it is conceivable that energy can be transferred from the vehicle to the ID transmitter 140 via the NFC interface 13.2. This allows the ID transmitter 140 to be charged, enabling, for example, communication with the sensor unit 13, a door control unit, or a vehicle control unit for an unlocking and / or opening signal and / or authentication signal.

[0085] Fig. 3a shows another possible embodiment of a cover device 110 according to the invention with a handle arrangement 10. Comparable to the embodiments of ßols & Vogel.

[0086] In Figures 2a and 2b, the handle assembly 10 has a handle body 11. The handle body 11 is shown in operating position II in Figures 3a and 3b.

[0087] According to Fig. 3a, the handle assembly 10 comprises an electronics unit 16 and a sensor unit 13. The sensor unit 13 has a first sensor 13.1, which is arranged in or on the handle body 11. The sensor 13.1 can, for example, be designed as a capacitive or inductive sensor. In the illustrated embodiment, the sensor 13.1 is arranged in an engagement recess 11.2 of the handle body 11, so that a user's hand interacts with the sensor 13.1 when the handle body 11 is actuated. Furthermore, a force sensor 13.4 is provided. The force sensor 13.4 is arranged in or on the handle body 11 in Fig. 3b and can detect a force exerted on the handle body 11. In the illustrated embodiment, the NFC interface 13.2 in the area of ​​the handle body 11 is also suitable for communicating with an ID transmitter and, for example, exchanging electrical energy between the ID transmitter and the vehicle.For this purpose, the intervention area 12 is specifically designed so that an ID transmitter, in particular a smartphone, can be placed there.

[0088] Furthermore, the handle assembly 10 of Fig. 3a includes a UWB unit 13.3. Alternatively or additionally, a Bluetooth interface, in particular Bluetooth Low Energy (BLE), can be provided.

[0089] The surface 11.2 of the engagement recess 11.1 has a structure. In particular, the handle body 11 has at least a partially structured and / or rubberized surface 11.2. This design improves ergonomics and haptics. It also allows the user to feel where the actuation area is located. Slipping can be further reduced by a structured surface 11.2. In the illustrated embodiment, the handle assembly 10 has a mechanical emergency release 17. The mechanical emergency release comprises a cover element 17.2. A connecting element is arranged on or behind the cover element 17.2, with which a mechanical connection to the locking device is achieved. By releasing the cover element 17.2, a user can grasp the connecting element, or the cover element 17.2 is connected to the connecting element in such a way that removal of the cover element 17.2 is not possible.2. Actuation of the connecting element is achieved, thereby opening or unlocking the locking device. ßols & Vogel.

[0090] Fig. 3b shows a motor vehicle door 100 from another perspective. Here, the view is from one end face of the door 100 towards the cover device 110 with the handle assembly 10. The motor vehicle door 100 also includes a window 150, a door panel 160, and a locking device 20, in particular an electrically operated locking device 20.

[0091] The handle assembly 10 has an actuating mechanism 14. The actuating mechanism 14 serves, in particular, to move the handle body 11 from the rest position to the operating position II shown, or vice versa. For this purpose, a spring assembly and / or a motor drive can be provided, for example. The actuating mechanism 14 thus moves or shifts the handle body 11 into operating position II or from operating position II to the rest position. In operating position II, the handle body 11 has a clearance so that the handle body 11 is arranged essentially parallel to the cover device 110 and forms an engagement area 12.

[0092] A sensor unit 13 is also arranged in the cover device 110. The sensor unit 13 can comprise at least one of the following components: capacitive or inductive sensor, NFC interface, UWB unit, force sensor and / or Bluetooth interface.

[0093] The locking device 20 is connected to the handle assembly 11 by means of a connecting element 17.1. Specifically, the connecting element 17.1 is connected at one end to the locking device, e.g., a lever for opening, and at the other end to a mechanical emergency release 17. The mechanical emergency release 17 is accessible, in particular, in the operating position II of the handle body 11 shown. Preferably, the emergency release 17 includes a cover element that conceals the connecting element 17.1 from the outside. Access to the connecting element 17.1 is only possible by removing the cover element. The connecting element 17.1 is preferably designed as a Bowden cable or rope. The connection to the locking device, in particular to a lever of the locking device, allows a user to open the locking device 20 even when the vehicle is without power and thus gain access to the vehicle / an occupant.

[0094] In particular, as can be seen in Fig. 3b, the handle arrangement 10, especially the handle body 11, is dimensioned such that the handle body 11 can also be used in its operating position.

[0095] II does not protrude beyond the door edge of the motor vehicle door 100. This also ensures compliance with the Federal Motor Vehicle Safety Standard (FMVSS). ßols & Vogel
