[0001] Wing element for a vehicle, in particular for a motor vehicle, as well as vehicle

[0002] The invention relates to a wing element for a vehicle, in particular for a motor vehicle. Furthermore, the invention relates to a vehicle, in particular a motor vehicle, with at least one such wing element.

[0003] WO 2007 / 118552 A1 discloses a motor vehicle with a vehicle door comprising a lower door section and an upper window section separated by a window sill. WO 2020 / 01137 A1 discloses a device for operating a vehicle door, including a sensor device configured to detect a force acting on the vehicle door and to generate corresponding sensor data. Furthermore, DE 102017202 114 A1 discloses a motor vehicle with at least one side door comprising a door body. WO 2006 / 007916 A1 also discloses a motor vehicle door with an inner module and an outer module.

[0004] The object of the present invention is to create a wing element for a vehicle and a vehicle with at least one such wing element, so that a particularly advantageous actuation of the wing element can be realized in a particularly space-saving manner.

[0005] This problem is solved according to the invention by a wing element having the features of claim 1 and by a vehicle having the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims.

[0006] A first aspect of the invention relates to a wing element for a vehicle, in particular for a motor vehicle. This means that the vehicle, preferably designed as a motor vehicle, in particular as a motor car and especially as a passenger car, has the wing element in its fully manufactured state. The wing element is understood to be a structural component that is movably, in particular pivotably, held or mounted on a body of the vehicle, for example, a self-supporting body, the interior of which is formed by the body, also referred to as the passenger cell, passenger compartment, or cabin. Thus, in the fully manufactured state of the vehicle, the wing element is formed separately from the body and is movably, in particular pivotably, mounted on the body. In particular, the wing element is associated with an opening in the body.The wing element can be moved, in particular pivoted, relative to the vehicle body between a closed position and at least one open position. In the closed position, the wing element closes at least a portion of the vehicle body opening. In the open position, the wing element releases the portion of the vehicle body opening, which is designed, in particular, as a passageway. The wing element can, for example, be a door, especially a side door, so that the vehicle body opening is designed, for example, as a side or rear door opening. The door is also referred to as a vehicle door. Thus, for example, in the open position of the wing element, a person initially in the vicinity of the vehicle and therefore of the wing element can enter the interior through the released portion of the vehicle body opening.Furthermore, a person initially inside the vehicle can exit the interior via the accessible section and thus access the surrounding area. It is also conceivable that the wing element is a flap, such as a tailgate or a front flap. For example, the wing element could be a trunk lid, a trunk cover, or a hood. Thus, the opening in the vehicle body could be a side or rear door opening, or a front or rear storage compartment opening, allowing access to a storage compartment, such as the trunk, at the front or rear of the vehicle via the section of the opening that is accessible when the wing element is open. Therefore, the wing element is a separate component, designed independently of the vehicle body, which is movable, particularly pivotable, and can be attached to or positioned on the body.

[0007] For example, the wing element has at least one base element which is, for instance, inherently rigid and thus dimensionally stable. In particular, the base element is a solid. Within the scope of this disclosure, the characteristic that an element such as the base element is inherently rigid and thus dimensionally stable means that the element is not, for example, a flexible element like a piece of fabric or a tensioning element such as a rope, which is flexible and thus dimensionally unstable and can therefore only transmit tensile forces but not compressive forces. Rather, the element retains its shape independently when considered in isolation, so that both compressive and tensile forces can be transmitted via the element.

[0008] The wing element has a handle element, which is designed separately from the base element and is movable, particularly relative to the base element, from a starting position to an operating position, especially rotationally and / or translationally. By moving the handle element from the starting position to the operating position, particularly relative to the base element, a lock can be mechanically, particularly purely mechanically and thus without the use of electrical energy, by means of which the wing element, which is movable, particularly pivotable, on the vehicle body between the closed position and at least one open position, is secured in the closed position, particularly relative to the body.

[0009] The wing element, in particular the handle element, has, for example, a control element by which the lock can be electrically unlocked by operating, in particular by actuating, the control element, thus effecting an electrical unlocking of the lock. Particularly when the wing element is designed as a door, in particular as a side door, of the vehicle, the lock is a door lock or is also referred to as a door lock. In particular, the lock can be an integral part of the wing element and thus be movable, in particular pivotable, relative to the assembly between the closed position and at least one open position. In particular, the control element can be a mechanical control element such as a knob, a push button, or a button.For example, the operating element can be moved relative to a base element of the wing element between a first operating element position and a second operating element position, in particular rotationally and / or translationally. By operating, in particular by actuating, the operating element is moved, for example, from the first operating element position relative to the base element to the second operating element position, thereby electrically unlocking the lock. Furthermore, it is conceivable that the operating element is or has a touch-sensitive surface, whereby the operating element can be operated by a person directly touching the touch-sensitive surface with one of their fingers.The handle element is, for example, an external handle element, particularly one located on the outside of the door, which is thus arranged, for instance, on the outer side of the wing element. Especially when the wing element is a door, particularly a side door, the handle element is therefore an external handle element, i.e., an external door handle, which is also referred to as an external door handle or door exterior handle. The handle element is arranged on the outside, with the outside, in the installed position of the wing element and in the closed position of the wing element, facing away from the interior and towards the surroundings of the vehicle, particularly in the transverse direction of the vehicle. The wing element assumes its installed position in the fully manufactured state of the vehicle incorporating the wing element.

[0010] The lock can be adjusted, for example, between a locked and an unlocked state. Unlocking the lock moves it from the locked to the unlocked state. If the sash is in the closed position and the lock is in the locked position, the sash is secured in the closed position by the lock, particularly by positive locking, and thus protected against unwanted movement relative to the frame into the open position. To open the sash, i.e., to move it from the closed to the open position, the operating element is operated, particularly by a person.This unlocks the lock, thus transferring it from the locked to the unlocked state, so that the lock releases the sash element for movement relative to the body from the closed to the open position. For example, a locking element, such as a locking bolt (also called a lock pin) or a locking bar (also called a lock bolt), is attached to the body, in particular to a vehicle pillar of the body, such as a door pillar or body pillar. In the closed position of the sash element and in the locked state of the lock, the lock, in particular a rotary and / or fork latch of the lock, interacts with the locking element, in particular positively, thereby securing the sash element in the closed position, in particular positively.For example, the lock has a first locking element, which can be, for instance, the aforementioned rotary and / or fork latch. In the closed position of the wing element and in the locked state of the lock, the lock interacts with a second locking element, which is, for example, the locking element. The second locking element is attached, at least indirectly, and in particular directly, to the structure, especially to a vehicle pillar, in such a way that relative movements between the second locking element and the structure, especially between the second locking element and the vehicle pillar, are prevented. In particular, in the closed position of the wing element and in the locked state of the lock, the first locking element interacts positively with the second locking element.Because the first lock element interacts with the second lock element, particularly in a positive-locking manner, in the closed position of the sash element and in the locked state of the lock, the sash element is secured or protected in the closed position, particularly in a positive-locking manner. For example, the first lock element can be moved between a locked position and an unlocked position, particularly translationally and / or rotationally, relative to a reference element of the lock and, in particular, relative to the second lock element (locking element). In the closed position of the sash element and in the locked position of the first lock element, the first lock element interacts with the second lock element, particularly in a positive-locking manner, thereby securing or protecting the sash element in the closed position, particularly relative to the structure.By unlocking the lock, for example, the first lock element is moved from the locked position to the unlocked position, in which the first lock element no longer interacts with the second lock element. This releases the wing element for movement relative to the assembly from the closed position to the open position. The characteristic that the lock can be electrically unlocked by operating, in particular by actuating, the control element, and thus that electrical unlocking of the lock can be effected, is to be understood in particular as meaning that, for example, as a result of operating the control element, an electrically operated lock actuator, which is designed, for example, as an electric motor, is electrically controlled.This electrical control of the lock actuator enables it to be electrically operated, allowing the first lock element to be moved from the locked position to the unlocked position, primarily using electrical energy. This means that the first lock element is moved electrically from the locked position to the unlocked position, thereby unlocking the lock electrically, i.e., using the aforementioned electrical energy.The movement of the sash element from the closed position to the open position following the electrical unlocking of the lock can, for example, be effected manually by a person, or by the aforementioned person, in particular by the person manually exerting a force, especially a pulling or pushing force, on the sash element, particularly via the handle element, thus moving the sash element relative to the structure from the closed position to the open position. Furthermore, it is conceivable that, as a result of operating the control element, the sash element can be moved electrically, i.e., using electrical energy, from the closed position to the open position relative to the structure, or is moved, particularly after the lock has been unlocked, especially electrically.For this purpose, an electrically operated motion device is provided, which includes, for example, the aforementioned electrically operated lock actuator and / or at least one other electrically operated actuator. As a result of operating the control element, the motion device is activated, particularly electrically, thereby electrically operating the motion device. This allows the motion device to move, in particular pivot, the sash element relative to the structure from the closed position to the open position using electrical energy. Thus, the lock can be unlocked with particular ease, and the sash element can be opened with particular ease, i.e., moved from the closed position to the open position.It is conceivable that the wing element, in particular the handle element and especially the operating element, has at least one sensor, in particular an electrical or electrically operated sensor, by means of which an operation, in particular activation, of the operating element by a person can be detected. If, for example, the sensor detects an operation, in particular activation, of the operating element by a person—that is, in particular a movement of the operating element from the first operating element position to the second operating element position by a person—then, in particular as described above, the lock actuator is activated so that the lock is electrically unlocked by means of the lock actuator. The lock actuator can be part of the wing element.Furthermore, it is conceivable that the sensor is a component of the wing element, in particular a component of the handle element, and most especially a component of the operating element. The lock can also be a component of the wing element.

[0011] In principle, it is possible, for example as a result of a vehicle accident, that the control element and / or the sensor and / or the lock actuator may no longer receive electrical power, because, for example, the power supply to the control element and / or the lock actuator and / or the sensor is damaged, interrupted, or destroyed. In that case, the lock may no longer be able to be unlocked electrically, because, for example, the lock actuator can no longer operate and / or because, for example, the sensor can no longer detect any operation or activation of the control element.To ensure that the wing panel can be opened quickly and easily, especially after a vehicle accident, the handle can be moved from its initial position to the operating position. This allows the lock to be unlocked mechanically, and therefore purely mechanically, without the use of electrical energy. Thus, for example, after a vehicle accident, a first responder near the vehicle and therefore the wing panel can quickly and easily move the handle from its initial position to the operating position, thereby unlocking the lock mechanically. This allows the first responder to quickly and easily open the wing panel and, for example, access the interior to reach and assist a person inside.The handle element is or functions as an emergency release element, by means of which the lock can be mechanically unlocked, in particular in an emergency.

[0012] For example, the wing element can have a locking device, which is formed separately from the base element and preferably separately from the handle element, and which is movable relative to the base element and relative to the handle element from a locking position to a release position. In particular, the locking device is held on the base element so that it can be moved from the locking position to the release position relative to the base element.

[0013] In the locked position, for example, the locking device prevents the handle from moving from its initial position to its operating position. In other words, the locking device secures the handle against movement from its initial position to its operating position. Put another way, the locking device prevents or prevents the handle from moving from its initial position to its operating position.This prevents unwanted movement of the handle from its initial position to the operating position, for example, in a normal vehicle condition where no accident has occurred. This allows a person to exert force on the handle and, via the handle, on the wing element to manipulate it—that is, to move it relative to the vehicle body—without causing unwanted movement of the handle from its initial position to the operating position. The force applied can be either tensile or compressive. However, in the release position, the locking device releases the handle, preventing movement from its initial position to the operating position.This means that in the release position, the locking device allows the handle to move from its initial position to the operating position. Therefore, if the locking device is in the release position after a vehicle accident, the aforementioned first responder can quickly and easily move the handle from its initial position to the operating position, thus unlocking the door. The person can then quickly and easily open the door and gain access to the interior.

[0014] For example, the wing element has a connecting element that is preferably rigid and is designed separately from the base element, the handle element, and the locking device. This connecting element can, for example, be a rod, i.e., a connecting rod. The connecting element engages, for example, in a receptacle of the locking device and is thereby connected to the locking device, particularly by a pivot. For example, it is provided that, by engaging the connecting element in the receptacle, the connecting element penetrates, in particular completely, the receptacle.The wing element, for example, also includes an actuator, also referred to as an actuator, which is designed separately from the base element, the handle element, the locking device, and the connecting element, and which can be electrically operated, for example. This actuator drives the locking device via the connecting element, thereby moving it from the locked position to the unlocked position. For example, the connecting element can be coupled or connected to the actuator, particularly by means of a hinge and, most notably, by means of a rotatable joint. The actuator drives the locking device via the connecting element, thereby moving it from the locked position to the unlocked position.

[0015] For example, if a vehicle's safety device detects an actual accident involving the vehicle and / or if an electronic computing device in the vehicle determines, in particular calculates, that the probability of a future accident exceeds a predefined threshold, the actuator is activated, particularly electrically. This activation of the actuator drives the connecting element, thereby moving it relative to the base element and, for example, relative to the handle element. This movement of the connecting element drives the safety device, moving it from the locked position to the unlocked position relative to both the base element and the handle element.Thus, by operating the actuator as described above, the safety device is driven by the actuator via the connecting element and thereby moved from the safety position to the release position.

[0016] The wing element further comprises a cable, for example designed as a Bowden cable, by which the lock can be mechanically actuated, in particular purely mechanically and thus without the use of electrical energy, and thereby mechanically unlocked, in particular purely mechanically and thus without the use of electrical energy, by moving the handle element from the starting position to the operating position. The cable is or comprises, for example, a particularly flexible and thus shape-unstable pulling element, which is designed, for example, as a pull rope. For example, the pull rope is a wire rope.

[0017] The cable pull has a coupling element on the handle side, via which the cable pull is coupled to the handle, in particular mechanically and preferably purely mechanically, and thus without the use of electrical energy. For this purpose, the coupling element is coupled to the handle, at least indirectly or directly, mechanically, in particular purely mechanically, thereby coupling the cable pull to the handle, in particular mechanically, in particular purely mechanically. Thus, if, for example, a person moves the handle from the starting position to the operating position, the cable pull is thereby driven and moved, in particular relative to the base element, in particular translationally. In particular, the cable pull is driven mechanically, in particular purely mechanically, by the handle element and thus moved, in particular relative to the base element, in particular translationally.By moving the cable, particularly relative to the base element, the lock is actuated mechanically, and in particular purely mechanically, and thereby unlocked mechanically, and in particular purely mechanically. In order to achieve a particularly advantageous actuation of the wing element in a space-saving manner, the invention provides that the coupling element has a first sub-section and a second sub-section directly adjoining the first sub-section. The first sub-section has a spherical segment shape on its outer circumference, thus having the shape of a spherical segment. The second sub-section has a cylindrical shape on its outer circumference, thus having the shape of a right circular cylinder.The feature that the sections connect directly to one another, meaning that the second section connects directly to the first and vice versa, means that no other, further section of the coupling element is arranged between the sections. Since the first section is spherical segment-shaped and the second section is cylindrical, particularly high forces, especially tensile forces, can be transmitted between the handle element and the cable, and especially from the handle element to the cable. This allows the lock to be mechanically, and in particular purely mechanically, unlocked by means of the handle element and the cable, even after a vehicle accident. Furthermore, the coupling element itself, considered on its own, can be designed to be particularly space-saving.In particular, the width of the coupling element, which runs transversely across the vehicle when the wing element is installed and closed, can be kept especially small, thus minimizing the space required for the coupling element and, consequently, the cable pull. This is particularly advantageous when the wing element is designed as the aforementioned door, as space is often very limited in or around such doors. Because the coupling element can be designed to be particularly space-efficient, the coupling element and the cable pull can be arranged or routed very advantageously, especially inside the wing element.

[0018] For example, the coupling element, and thus the cable pull via the coupling element, is suspended in a corresponding suspension element, whereby the coupling element is coupled, at least indirectly, and in particular directly, to the handle element, preferably mechanically, and in particular purely mechanically. It is conceivable that a transmission part of the cable pull connects to the first part in a direction extending from the first part and away from the second part, in particular directly, wherein the transmission part comprises, for example, the aforementioned traction element. For example, the transmission part is or comprises the traction element as a strand, as well as, for example, a sheath encasing and thus surrounding the strand, also referred to as a sheath or casing.For example, the coupling element is mechanically, and in particular purely mechanically, coupled to the lock via the transmission part, such that by moving the handle element from the starting position to the operating position, the coupling element and, via the coupling element, the transmission part can be actuated and thus, in particular, moved relative to the base element. This movement of the coupling element and the transmission part, particularly relative to the base element, allows the lock to be actuated, in particular mechanically and, most especially, purely mechanically, thereby unlocking the lock mechanically, and in particular purely mechanically. In particular, the transmission part extends, for example, in the aforementioned direction away from the first section.Because the first section is formed as a spherical segment on the outer circumference, an advantageous seal of the cable can also be achieved, thus preventing, for example, water from penetrating the cable. The invention is particularly advantageous when the wing element is designed as the aforementioned door, since, for example, the coupling element is arranged in a door channel, also referred to as a shaft. In this door channel, there is typically only a very narrow width available, extending transversely in the vehicle direction in both the installed position and the closed position of the wing element, to accommodate the cable and thus the coupling element. The invention now allows for a particularly space-saving design of the cable, enabling the cable to be advantageously arranged and routed within the door channel.

[0019] In order to design the coupling element and thus the cable pull in a particularly space-saving manner, one embodiment of the invention provides that the spherical segment-shaped first section is simply a segment of an imaginary sphere, whose first radius is also designated R1. The second section is a cylinder on its outer circumference, specifically an imaginary circular cylinder. This imaginary circular cylinder has two imaginary, opposing circular bases, each with the same second radius.

[0020] The first radius, for example, runs in an imaginary first plane, and the respective second radius runs in a respective imaginary second plane, with the second planes running parallel to each other and with the respective second plane running perpendicular to the first plane.

[0021] It has proven particularly advantageous if the second radius is smaller than the first radius. This allows the coupling element to be designed in a particularly space-saving manner.

[0022] Another embodiment is characterized by the fact that a first center point of the imaginary sphere and a second center point of each imaginary base lie on an imaginary common line. This line runs perpendicular to the imaginary second planes and within the imaginary first plane. This allows the advantages of the spherical segment-shaped first section to be utilized, particularly with regard to coverage and the transmission of high forces, while simultaneously enabling a particularly space-saving design of the coupling element.

[0023] In order to design the coupling element in a particularly space-saving manner, it is further provided in the invention that the cylinder is rotationally symmetrical with respect to the imaginary straight line.

[0024] In a further particularly advantageous embodiment of the invention, the first sub-section is supported directly on the handle element, whereby the coupling element is connected to the handle element, in particular by a pivot. Thus, for example, the aforementioned suspension element is part of the handle element. This allows the installation space requirement to be kept particularly low.

[0025] In order to achieve a particularly space-saving design of the wing element, a further embodiment of the invention provides that at least one lever element is provided which is designed separately from the handle element and is thus indirectly, in particular directly, and pivotally coupled to the handle element, which can be actuated by moving the handle element from the starting position to the actuating position and is thereby movable, in particular translationally and / or rotationally, relative to the base element from a first position to a second position.The handle element is coupled to the coupling element and thus to the cable via the lever element, so that by moving the handle element from the starting position to the actuating position, and thus by the resulting movement of the lever element from the first position to the second position, the cable can be actuated mechanically, and in particular purely mechanically, by the handle element via the lever element, and the lock can be actuated mechanically, and in particular purely mechanically, by the handle element via the lever element, thereby unlocking the lock mechanically, and in particular purely mechanically. It is preferably provided that the first section is directly supported on the lever element, whereby the coupling element is connected, in particular articulatedly, to the lever element and, via the lever element, in particular articulatedly, to the handle element. Thus, the aforementioned attachment element is preferably part of the lever element.

[0026] Another embodiment is characterized by the fact that the coupling element is formed at a free end of the cable, which allows for a particularly space-saving design.

[0027] Finally, it has proven particularly advantageous for realizing a particularly space-saving construction method if the sub-areas are flush with each other on the outer perimeter and especially along the straight lines, thus without offset, i.e. without edge.

[0028] A second aspect of the invention relates to a vehicle, preferably designed as a motor vehicle, in particular as a motor car and most especially as a passenger car, which has at least one wing element according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention and vice versa.

[0029] Further details of the invention will become apparent from the following description of a preferred embodiment with the accompanying drawings. These show:

[0030] Fig. 1 shows a partial schematic perspective view of a vehicle with at least one wing element; and

[0031] Fig. 2 shows a partial schematic perspective view of a cable pulley system, via which a lock for securing the wing element can be mechanically unlocked by means of a handle element on the wing element. In the figures, identical or functionally equivalent elements are designated with the same reference numerals.

[0032] Fig. 1 shows a partial schematic perspective view of a vehicle 1, in this case designed as a passenger car, whose interior, also referred to as passenger compartment, passenger space, or conduit, is formed by a body structure of the vehicle 1, in particular designed as a self-supporting body. During a journey, persons such as the driver of the vehicle 1 can be present in the interior. The vehicle 1 has at least one wing element 2, which is designed as a door, in particular as a side door, and is therefore also referred to as a vehicle door. A body opening, in particular a lateral opening, is associated with the wing element 2, the body opening being designed in this case as a side door opening. The wing element 2 is attached to the body between a [missing information] shown in Fig.The wing element 2 is arranged to be movable, in particular pivotable, relative to the body in the closed position shown in Fig. 1 and in at least one open position not shown in the figures. In the closed position of the wing element 2 shown in Fig. 1, at least a portion of the body opening is closed by the wing element 2. In the open position, the wing element 2 releases at least this portion of the body opening, so that, for example, a person initially located in the vicinity 3 of the vehicle 1 can enter the interior via the released portion of the body opening. Furthermore, for example, a person initially located in the interior can exit the interior via the released portion and thus access the vicinity 3.

[0033] The wing element 2 has a handle element 4, which is designed on the outside and thus serves as an external door handle. The handle element 4 is movable relative to at least one base element of the wing element 2 from a starting position AS to an operating position, in particular translationally and / or rotationally. In particular, in the embodiment shown in the figures, the handle element 4 is held on the aforementioned base element such that the handle element 4 is movable relative to the base element from the starting position AS to the operating position, in particular rotationally and / or translationally. The wing element 2 has, for example, a lock (not shown in detail in the figures), also referred to as a door lock, by means of which the wing element 2 is secured or locked in the closed position relative to the structure.The lock can be adjusted between a locked and an unlocked state. If the wing element 2 is in the closed position while the lock is in its locked state, the wing element 2 is held in the closed position relative to the structure by the lock, in particular by a positive locking mechanism. By unlocking the lock, the lock can be moved from the locked to the unlocked state. In the unlocked state, the lock releases the wing element 2 for movement relative to the structure from the closed to the open position.

[0034] By moving the handle element 4 from the initial position AS to the operating position, the door can be unlocked mechanically, in particular purely mechanically and thus without the use of electrical energy, and thus moved from the locked state to the unlocked state. The sash element 2, for example, has a rough frame, also referred to as the door frame. Furthermore, the sash element 2 has an outer cladding element 5, also referred to simply as the paneling element, which is, for example, formed separately from the rough frame and is held at least indirectly, in particular directly, by the rough frame. Thus, for example, at least a partial area of ​​the rough frame facing the surroundings 3 is covered and thus clad by the outer cladding element 5, at least in the closed position of the sash element 2.The wing element 2 has an outer skin, also referred to as the overall outer skin 6, which, at least in the closed position of the wing element 2, is visually and haptically perceptible to a person in the vicinity 3, i.e., it can be seen and, in particular, directly touched. A first area B1 of the overall outer skin 6 is formed by the outer cladding element 5. A second area B2 of the overall outer skin 6 is formed by the handle element 4, which is also referred to as the handle element outer skin.

[0035] It is evident that the handle element 4 is arranged on an outer surface A of the wing element 2 and is therefore an external, in particular door-side, handle element. In the closed position of the wing element 2, the outer surface A, particularly in the transverse direction of the vehicle 1, faces outwards away from the interior and towards the surroundings 3. For example, a third area of ​​the overall outer skin 6 is formed by an outer trim element of the wing element 2, also referred to as a cover or simply as a panel element, such that, for example, the third area of ​​the overall outer skin 6 is formed by an element outer skin of the cover.By means of the cover, for example, at least in the closed position of the wing element 2, a partial area of ​​a vehicle pillar of the body, also referred to as a superstructure pillar or body pillar, is overlapped to the outside, particularly in the transverse direction of the vehicle 1, and thereby covered, wherein, for example, the vehicle pillar is a B-pillar.

[0036] For example, the superstructure opening associated with wing element 2 is at least partially limited to the rear by the vehicle pillar in the longitudinal direction of vehicle 1. For example, the outer paneling element 5 and the cover are immovable relative to each other.

[0037] As can be seen from Fig. 1, the wing element 2, which is designed as a door, has a door sill 7, also referred to as a parapet or window sill. Furthermore, the wing element 2 includes a translucent side pane 8, also referred to simply as a pane, which is movable relative to the vehicle body and relative to the outer cladding element 5, for example, in the vertical direction of the vehicle 1. In particular, the side pane 8 is movable, i.e., repositionable, between a closed position shown in Fig. 1 and an open position relative to the vehicle body and relative to the outer cladding element 5. The door sill 7 defines a pane area 9, also referred to as a window area, which is limited downwards in the vertical direction of the vehicle 1, at least with respect to the closed position of the wing element 2.In the embodiment shown in the figures, the pane area 9 is a window opening, which is bounded, for example, by a window frame of the sash element 2, wherein the window frame can, for example, include the door sill 7. In the closed position, the side pane 8 is arranged in the pane area 9, also referred to as the window area, in particular such that the pane area 9 is at least partially, and in particular at least predominantly and thus at least more than halfway or completely, closed by the side pane 8.In particular, it is provided that, in the closed position of the side window 8, the door sill 7, in the installation position of the wing element 2, and in the closed position of the wing element 2, in the vehicle 1's vertical direction, adjoins the side window 8 downwards, wherein the wing element 2 assumes its installation position in the fully manufactured state of the vehicle 1, and wherein the installation position of the wing element 2 is shown in Fig. 1. It can be seen that, at least in the closed position of the wing element 2 and at least in the initial position AS, and preferably also in the operating position, the handle element 4 is arranged above the door sill 7 in the vehicle 1's vertical direction.

[0038] As can be seen from Fig. 2, the wing element 2 has a cable 10 via which the handle element 4 is mechanically, and in particular purely mechanically, coupled or can be coupled to the lock. By moving the handle element 4 from the initial position AS to the operating position, the lock can be actuated mechanically, and in particular purely mechanically, via the cable 10, and thereby unlocked mechanically, and in particular purely mechanically. If the handle element 4 is moved from the initial position AS to the operating position, and in particular relative to the base element and relative to the outer cladding element 5, the cable 10 is thereby driven by the handle element 4 and thereby moved, in particular translationally, relative to the base element and relative to the outer cladding element 5.By moving the cable 10 relative to the outer cladding element 5 and, for example, also relative to the base element, the lock is actuated mechanically, in particular purely mechanically, and thereby unlocked mechanically, in particular purely mechanically.

[0039] The cable pull 10 has a coupling element 11 on the handle element side, which in the embodiment shown in the figures is indirectly and preferably pivotally coupled to the handle element 4, so that the cable pull 10 is mechanically, in particular purely mechanically, coupled to the handle element 4 via the coupling element 11, in particular pivotally coupled.

[0040] As can be seen in part in Fig. 2, a lever element 12 is visible, which is formed separately from the handle element 4, the cable pull 10, the base element, and the outer cladding element 5, and which is coupled to the handle element 4 at least indirectly, and in particular directly. For example, the handle element 4 and the lever element 12 are pivotally coupled to each other. When the handle element 4 is moved from the initial position AS to the actuating position, particularly relative to the base element and the outer cladding element 5, the lever element 12 is driven and thereby moved relative to the base element and the outer cladding element 5, in particular translationally and / or rotationally, from a first position shown in Fig. 2 to a second position.By moving the lever element 12 from the first position to the second position, the cable pull 10 is driven by the lever element 12 and thereby moved relative to the base element and relative to the outer paneling element 5, in particular at least translationally, whereby the lock is actuated, in particular purely mechanically, and thereby unlocked, in particular purely mechanically. As can be seen from Fig. 2, the coupling element 11 is directly coupled to the lever element 12, in particular by a pivot, so that the coupling element 11 is mechanically, in particular purely mechanically, and preferably pivotally, coupled to the handle element 4 via the lever element 12, and so that the cable pull 10 is mechanically, in particular purely mechanically, and preferably pivotally, coupled to the lever element 12 via the coupling element 11 and to the handle element 4 via the lever element 12.

[0041] It can be seen that the lever element 12 has a suspension element 13 into which the coupling element 11 is suspended, thereby connecting the coupling element 11, in particular by a pivot, to the lever element 12. For example, the lever element 12 is formed in one piece, that is, from a single component. For example, the cable 10 is designed as a Bowden cable.

[0042] In order to ensure that the lock can be reliably unlocked mechanically, and in particular purely mechanically, especially after an accident involving vehicle 1, and thus to achieve advantageous actuation of the wing element 2 as well as a particularly space-saving design of the wing element 2, the coupling element 11 has a first sub-area T1, a second sub-area T2 and, in this case, also a third sub-area T3, wherein the sub-area T2 connects directly to the sub-areas T1 and T3 in such a way that the sub-area T2 is arranged between the sub-areas T1 and T3.This means that sub-area T1 connects directly to sub-area T2 in a first direction, illustrated by arrow 14, and that sub-area T3 connects to sub-area T2 in a second direction, illustrated by arrow 15, wherein the first direction originates from sub-area T2 and points away from sub-area T3, wherein the second direction originates from sub-area T2 and points away from sub-area T1, and wherein the second direction is opposite to the first direction and vice versa, and wherein, for example, the first and second directions run along an imaginary straight line. Figure 2 shows that the respective sub-areas T1 and T3 have a spherical segment shape on their outer circumference.This means that the respective sub-areas T1 and T3 are formed on their outer circumference in the form of a segment of an imaginary sphere, also referred to as a spherical segment. In this case, the spherical segment-shaped sub-areas T1 and T3 are segments of the same imaginary sphere. This imaginary sphere, whose center is also designated M1, has a first radius, also designated R1. The second sub-area T2 is cylindrical on its outer circumference, so that the sub-area T2 is formed on its outer circumference in the form of a right circular cylinder, the height of which coincides with the aforementioned imaginary line and thus extends along it. The center M1 of the imaginary sphere lies on this imaginary line. The right circular cylinder has two bases opposite each other and spaced apart along the imaginary line.Each base, whose second center point is also denoted by M2, lies in a corresponding plane. These planes are perpendicular to the imaginary line, parallel to each other, and spaced apart along this line. The height of the right circular cylinder and the first center point of the sphere, and thus the imaginary line, lie in a spherical plane that, for example, bisects the imaginary sphere. This spherical plane is perpendicular to the planes of the bases. Each base has a second radius, and these second radii are equal. The second radii of the bases are also called base radii. Thus, one of the imaginary bases has one base radii, and a second of the imaginary bases has a second base radii.The first imaginary base lies in one of the imaginary planes, and the second imaginary base lies in a second imaginary plane. The radius of the first base lies in the first imaginary plane, and the radius of the second base lies in the second imaginary plane. The radius of the first imaginary sphere is smaller than the radii of the bases. This allows the width of the coupling element 11, which runs parallel to the planes of the bases, to be kept particularly small. Furthermore, the centers of the bases and the center of the imaginary sphere lie on the aforementioned imaginary line, which coincides with the height of the right circular cylinder. With respect to this imaginary line, the right circular cylinder, and thus the sub-section T2, is rotationally symmetric.

[0043] As can be seen in Fig. 2, section T1 is directly supported on the lever element 12, whereby the cable 10 is coupled, in particular by a pivot, to the lever element 12 and via this to the handle element 4. It is also evident that the coupling element 11 is formed at a free end E of the cable 10. Furthermore, sections T1, T2, and T3 are designed to merge seamlessly along the imaginary straight line and, when viewed in pairs, without any offset or edge. The coupling element 11 is thus barrel-shaped on its outer circumference, which allows the aforementioned width of the coupling element 11 to be kept particularly small. This enables a particularly space-saving design of the wing element 2.

[0044] As can also be seen from Fig. 2, a transmission part 16 of the cable pull 10 is directly connected to the section T1 in the first direction illustrated by arrow 14, wherein the coupling element 11 can be mechanically, in particular purely mechanically, coupled to the lock via the transmission part 16. Forces exerted on the handle element 4 to move it from the initial position AS to the actuating position are transmitted mechanically, in particular purely mechanically and thus without the use of electrical energy, from the handle element 4 to the lever element 12, from the lever element 12 to the coupling element 11, from the coupling element 11 to the transmission part 16, and from the transmission part 16 to the lock, thereby unlocking the lock mechanically, in particular purely mechanically and thus without the use of electrical energy.The transmission element 16 is or comprises, for example, a stranded wire, which may be designed, for instance, as a flexible and thus deformable traction element when considered in isolation. Furthermore, the transmission element 16 comprises, for example, a sheath that surrounds and thus encases or encases the stranded wire, such that, for example, the stranded wire runs at least partially within the sheath. Because the outer circumference of the sub-section T1 is spherically segmented, the stranded wire and / or the sheath can be advantageously sealed, particularly against the sub-section T1, thus advantageously preventing, for example, the ingress of water into the stranded wire and / or the sheath. In addition, particularly high forces can be transmitted from the handle element 4, in this case via the lever element 12, to the cable 10, so that the lock can be advantageously unlocked mechanically, and in particular purely mechanically, even after an accident involving the vehicle 1.
