The invention relates to an operating element for a motor vehicle, in particular for a motorcycle or a motorized tricycle. Furthermore, the invention relates to a motor vehicle with at least one such control element.

The EP 1 815 594 B1 discloses a shifting device for a motor vehicle, with a control device connected to a motor vehicle transmission, the shifting device having a bracket and a selector lever pivotally mounted on the bracket via a ball joint. Furthermore, the EP 0 357 274 A2 a joystick control device having a lever and pivoting means to support the lever for pivotal movement in two orthogonal directions. Furthermore, from the U.S. 4,733,214 known control element.

The object of the present invention is to create an operating element for a motor vehicle and a motor vehicle so that the motor vehicle can be operated in a particularly advantageous manner using the operating element.

According to the invention, this object is achieved by an operating element having the features of patent claim 1 and by a motor vehicle having the features of patent claim 10 . Advantageous configurations of the invention are the subject matter of the dependent claims.

A first aspect of the invention relates to an operating element for a motor vehicle, in particular for a motorcycle or a motorized tricycle. In the context of the present disclosure, a or the above-mentioned motorcycle is to be understood as a two-wheeled motorcycle, i.e. a motorcycle with exactly one track and with exactly two wheels, which can be driven by means of a drive motor of the motorcycle designed, for example, as an internal combustion engine or as an electric motor. The wheels are ground contact elements, via which the motorcycle or the motor vehicle can be supported or is supported on a roadway downwards in the vertical direction of the vehicle. If the motor vehicle is driven along the roadway while the motor vehicle is supported on the roadway via the wheels in the vehicle vertical direction, the wheels roll off the roadway, in particular directly. The wheels are also referred to as vehicle wheels. Furthermore, within the scope of the present disclosure, one or the aforementioned motorcycle is to be understood as a motorcycle with a sidecar, i.e. a vehicle that has a motorcycle that has exactly one track and exactly two wheels, the vehicle also having one has a sidecar coupled to the actual motorcycle with at least or precisely one third wheel which is held rotatably on the sidecar, the sidecar itself, i.e. viewed on its own, being motorless, i.e. not having its own motor for driving the sidecar. The sidecar is coupled to the actual motorcycle and can be driven by the actual motorcycle. In the context of the present disclosure, a or the above-mentioned motorized tricycle is to be understood as a tricycle which has exactly three wheels and a drive motor designed, for example, as an internal combustion engine or electric machine, by means of which the wheels can be driven.

The operating element has a guide link which has two link tracks which cross one another, that is to say which run crosswise. For example, the respective link track has a respective direction of longitudinal extension, along which the respective link track extends in an elongated and preferably straight manner. The link tracks or their directions of longitudinal extent preferably run perpendicular to one another, so that the guide link is preferably designed as a so-called cross link. The link tracks are preferably of the same length. Provision is preferably made for the link paths to cross one another in their centers, so that the centers of the link paths are, so to speak, on top of one another or on top of one another.

The control element has a first lever arm, which is mounted on a base element of the control element such that it can pivot about a first pivot axis. Furthermore, the operating element comprises a second lever arm, which is mounted on the first lever arm such that it can pivot about a second pivot axis. The first pivot axis runs perpendicular to the second pivot axis. This means in particular that the pivot axes intersect, with the first pivot axis running perpendicular to the second pivot axis or vice versa. Furthermore, this means that the first pivot axis runs perpendicularly to a first plane and the second pivot axis runs perpendicularly to a second plane, the planes running perpendicularly to one another.

The control element also includes a control lever, also referred to as a joystick or control stick, which has a direction of longitudinal extension, which is also referred to as the direction of longitudinal extension of the lever. The direction in which the lever extends longitudinally runs obliquely or perpendicularly to the pivot axes. This is to be understood in particular that the lever length serstreckungsrichtung intersects the pivot axes and perpendicular to the pivot axes. It is also to be understood that the direction of longitudinal extension of the lever runs perpendicularly to a third plane, which runs obliquely or perpendicularly to the first plane and to the second plane. The operating lever engages in the guide link, in particular in the respective centers of the guide links, along the direction of its longitudinal extent.

The operating lever can be moved while being guided about the first pivot axis relative to the base element by pivoting the first lever arm along a first of the link tracks. In other words, the operating lever can be moved along the first link track and thus relative to the guide link and is guided by means of the first guide track. If the operating lever is moved along the first link track, the first lever arm is pivoted or pivoted about the first pivot axis relative to the base element. In addition, the operating lever can be moved, guided along the second slideway, while the second lever arm pivots about the second pivot axis relative to the first lever arm. In other words, the operating lever can be moved along the second link track and is guided by the second link track. If the operating lever is moved along the second link path, the second lever arm is thereby pivoted about the second pivot axis relative to the first lever arm. In particular, it is conceivable that when the operating lever is moved along the first link track, the first lever arm and also the second lever arm and preferably also the operating lever are pivoted or pivoted about the first pivot axis relative to the base element. Provision is also made, for example, for the second lever arm and the operating lever to be pivoted or pivoted about the second pivot axis relative to the first lever arm when the operating lever is moved along the second link track.

The control element also includes a first torsion spring that is or can be supported at least indirectly, in particular directly, on the base element and on the first lever arm, which is also referred to as the first torsion spring. In particular, the first torsion spring is, for example, a first torsion spring which can be or is supported at least indirectly, in particular directly, via its legs on the base element and on the first lever arm. The first torsion spring can be tensioned by pivoting the first lever arm about the first pivot axis relative to the base element. In other words, if the first lever arm is pivoted or pivoted about the first pivot axis relative to the base element, the first torsion spring is tensioned as a result. For example, the first lever arm can be pivoted about the first pivot axis in a first direction of rotation and in a second direction of rotation opposite the first direction of rotation relative to the base element. If, for example, the first lever arm is pivoted or pivoted from a first starting position in the first direction of rotation or in the second direction of rotation relative to the base element about the first pivot axis, the first torsion spring is tensioned as a result. As a result, the first torsion spring provides a spring force by means of which the first lever arm can be pivoted about the first pivot axis in the second direction of rotation or in the first direction of rotation relative to the base element and thereby moved into the first starting position.

The operating element also includes a second torsion spring, which is also referred to as a second torsion spring, which is or can be supported at least indirectly, in particular directly, on the first lever arm and on the second lever arm. For example, the second torsion spring is designed as a second torsion spring which is or can be supported at least indirectly via its legs on the first lever arm and on the second lever arm. The second torsion spring can be tensioned by pivoting the second lever arm about the second pivot axis relative to the first lever arm. In other words, if the second lever arm is pivoted or pivoted about the second pivot axis relative to the first lever arm, the second torsion spring is tensioned as a result. For example, the second lever arm can be pivoted about the second pivot axis in a third direction of rotation and in a fourth direction of rotation opposite the third direction of rotation relative to the first lever arm, ie pivoted or rotated. If, for example, the second lever arm is pivoted about the second pivot axis relative to the first lever arm in the third direction of rotation or in the fourth direction of rotation, ie rotated, the second torsion spring is tensioned as a result. As a result, the second torsion spring provides a spring force, by means of which the second lever arm can be rotated about the second pivot axis in the fourth direction of rotation or in the third direction of rotation relative to the first lever arm, as a result of which the second lever arm can be moved back into its second starting position. If, for example, the operating lever is moved along the respective link track by a force being exerted on the operating lever, for example by a person, the respective lever arm is pivoted about its respective pivot axis and thus deflected, i.e. from the respective starting position into one of the respective starting position moves different operating position. Besides that as a result, the operating lever is moved, for example, from a third starting position of the operating lever into a position of the operating lever that differs from the third starting position. If the force is then no longer exerted on the operating lever, so that no external force is acting on the operating lever, which can happen, for example, by the person releasing the operating lever, the respective torsion spring moves the respective lever arm back into the respective starting position, whereby the Operating lever is moved back from its position different from the third initial position to its third initial position. The lever arms and the torsion springs thus enable an actuation that is particularly advantageous in terms of haptics and has a particularly high-quality effect, i.e. movement of the operating lever along the link tracks, so that the operating element and, via this, the motor vehicle can be operated particularly advantageously by the aforementioned person. For example, at least one respective function of the motor vehicle can be effected by moving the operating lever along the respective link path. In particular, a menu selection can be carried out, for example, by moving the operating lever along the respective link path. This means, for example, that a menu with a number of selection options can be displayed on an electronic display of the motor vehicle. By moving the operating lever along the respective link path, the respective selection option can be selected, for example, in particular by the respective selection option being optically emphasized and/or marked. Furthermore, it is conceivable that the respective selection option is confirmed by means of the operating lever, ie selected, which will be explained in more detail below.

The operating element according to the invention can be used particularly advantageously for two-wheeled or three-wheeled motor vehicles, ie for motorcycles or motorized tricycles, since the operating lever and thus the operating element as a whole can also be operated by a person wearing gloves. This means that the aforementioned person can operate the operating lever particularly well with their hand, which is in a glove, that is to say can move it along the respective guide track, even though the hand is in the said glove.

The link tracks, which are also referred to as guide tracks, and the lever arms ensure precise and defined guidance of the operating lever, so that operating errors, i.e., for example, an undesired selection of a menu item or undesired activation of a function, can be at least almost completely ruled out. Furthermore, a particularly compact design of the operating element can be implemented. The operating element can thus be arranged particularly advantageously on a handlebar of the motor vehicle, for example, it being possible for the motor vehicle to change direction and corner by means of the handlebar of the motor vehicle. The invention also enables a needs-based and thus variable arrangement of the torsion springs, also referred to simply as springs, so that the control element is particularly flexible with regard to its arrangement in an available installation space and in particular with regard to components already installed. Furthermore, the operating element according to the invention can be implemented using a small number of simple components, so that the costs of the operating element can be kept within a particularly low range.

The third starting position of the operating lever, also referred to as a joystick, is also referred to as the zero position. The invention makes it possible to achieve a particularly good feel, since the zero position by means of the lever arms and the torsion springs is a defined position into which the operating lever is brought by means of the torsion springs via the lever arms, for example, always, in particular automatically or independently, that means is set when no external force acts on the operating lever. The operating lever is pretensioned in the four directions of rotation via the lever arms by means of the torsion springs.

This means that the operating lever can be or is acted upon by the lever arms by means of the torsion springs in the four directions of rotation with spring forces that are provided or can be provided by the torsion springs. It is particularly conceivable that the spring forces of the torsion springs act on the operating lever in the four directions of rotation when the operating lever is in the zero position, as a result of which the operating lever is held in its zero position in a particularly secure and defined manner. A particularly advantageous haptic can be realized as a result. This can be realized in particular in that the respective torsion spring is tensioned, ie pretensioned, in the respective starting position of the respective lever arm and thus in the third starting position of the operating lever, whereby particularly good haptics can be represented. In addition, when the operating lever is deflected by means of the respective link track, an advantageous force/path curve can be developed, as a result of which the operating lever can be operated particularly comfortably.

A haptically particularly advantageous actuation and thus operation of the operating lever and a particularly compact design of the control element, it is provided in an advantageous embodiment of the invention that the first lever arm has a first length region with a first longitudinal extension direction running obliquely or perpendicularly to the first pivot axis and a second length region with a direction obliquely or perpendicularly to the first Longitudinal direction of the first longitudinal region running, second longitudinal direction. In this case, the second lever arm is mounted on the second longitudinal region such that it can pivot about the second pivot axis relative to the first lever arm. For example, the first lever arm has a third length region with a third direction of longitudinal extent, which runs obliquely or perpendicularly to the first direction of longitudinal extent. It is preferably provided that the second direction of longitudinal extension of the second longitudinal area and the third direction of longitudinal extension of the third longitudinal area of the first lever arm run parallel to one another. Furthermore, it is preferably provided that the first lever arm is mounted on the base element such that it can pivot over its third length range about the first pivot axis relative to the base element.

A further embodiment is characterized in that the first lever arm is mounted on the base element via a sliding bearing, in particular without bearing play or with only a small bearing play. In this context, it has proven to be particularly advantageous if the plain bearing has exclusively metallic sliding partners, which are also referred to as row partners. As a result, a haptically particularly high-quality mounting of the first lever arm on the base element can be ensured, so that the operating element can be actuated and thus operated particularly well.

In a further, particularly advantageous embodiment of the invention, the first lever arm is mounted on the base element via a roller bearing, in particular via a ball bearing, as a result of which actuation and thus operation that is particularly advantageous in terms of haptics can be achieved. In particular, it is preferably provided that the first lever arm is exclusively roller-mounted on the base element, so that, for example, there is no sliding bearing of the first lever arm on the base element.

It has also been shown to be particularly advantageous if the second lever arm is mounted on the first lever arm via a plain bearing, in particular without bearing play or with only a small bearing play. It has proven to be particularly advantageous if the sliding bearing of the second lever arm on the first lever arm has exclusively metallic sliding partners, which are also referred to as row partners. As a result, a particularly high-quality haptic operation of the operating lever and thus of the operating element as a whole can be represented.

In order to be able to operate the operating lever haptically in a particularly advantageous manner and thus move it along the link tracks, it is provided in a further embodiment of the invention that the second lever arm is mounted on the first lever arm via a roller bearing, in particular via a ball bearing. As a result, it has been shown to be particularly advantageous if the second lever arm is exclusively mounted on roller bearings on the first lever arm.

In a further, particularly advantageous embodiment of the invention, the operating lever is mounted on the second lever arm in a displaceable manner along its direction of longitudinal extent. This means that the operating lever is moved in a translatory manner along its direction of longitudinal extent relative to the lever arms, that is to say it can be displaced. In particular, the respective selection option can be selected or confirmed, for example by moving the operating lever relative to the lever arms, so that a function of the motor vehicle assigned to the respective selection option can be effected.

In order to be able to ensure a particularly advantageous operation of the operating element, in a further embodiment of the invention a spring element is provided, in particular in addition to the torsion springs, which can be tensioned by moving the operating lever along the longitudinal extension direction of the operating lever relative to the second lever arm. In other words, if the operating lever, in particular from its zero position, is displaced in the direction of longitudinal extension of the operating lever relative to the lever arms, in particular in a first confirmation direction running parallel to the direction of longitudinal extension of the operating lever or coinciding with the direction of longitudinal extension of an operating lever, then the spring element which is preferably a mechanical spring tensioned. For example, the spring element is a helical spring. By tensioning the spring element, the spring element provides a spring force that acts, for example, at least indirectly, in particular directly, on the operating lever, in particular in a second operating direction opposite to the first operating direction, which, for example, runs parallel to the longitudinal direction of the operating lever or coincides with the longitudinal direction of the operating lever . The operating lever is moved in the second actuation direction relative to the lever arm by means of the spring force provided by the spring element and is thus moved back into the zero position. In particular is It is conceivable that the spring element is still somewhat tensioned in the zero position, as a result of which the spring element also provides the or a spring force in the zero position of the operating lever, which acts at least indirectly, in particular directly, on the operating lever in particular in the second actuation direction. As a result, the operating lever is held securely and in a defined manner in the zero position and, starting from the zero position, can be deflected, i.e. moved, in a particularly high-quality haptic manner.

Finally, it has been shown to be particularly advantageous if the operating element has a guide element which allows the operating lever to be displaced along the longitudinal extension direction of the operating lever relative to the second lever arm only in its rest position, in which the operating lever can be moved by means of the torsion springs. The rest position is the aforementioned zero position of the operating lever. This means that the guide element only allows the operating lever to be displaced relative to the lever arms along the longitudinal extension direction of the operating lever when the operating lever is in its rest position. In all other positions of the operating lever that differ from the rest position, which can be moved, for example, into the other positions along the link tracks, the guide element preferably prevents the operating lever from being displaced along the longitudinal direction of extension of the operating lever relative to the lever arms, as a result of which the operating element can be operated particularly well can.

A second aspect of the invention relates to a motor vehicle, preferably designed as a motorcycle or motorized tricycle, which has at least one operating element according to the first aspect of the invention. Advantages and advantageous configurations of the first aspect of the invention are to be regarded as advantages and advantageous configurations of the second aspect of the invention and vice versa.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

1 shows a first embodiment of a control element 1 for a motor vehicle, also referred to as a control device or control device, in a schematic and sectional plan view. This means that the motor vehicle includes the operating element 1 in its fully manufactured state. For example, the motor vehicle is a two-wheel or three-wheel motorcycle, ie a motorcycle without a sidecar or a motorcycle with a sidecar, or the motor vehicle is a motorized tricycle, which is also referred to as a trike. For example, the motor vehicle has a support structure that can be designed, for example, as a frame, in particular as a ladder frame. Furthermore, the motor vehicle has, for example, a link which is held on the support structure such that it can pivot about a steering axis relative to the support structure. By pivoting about the steering axis relative to the support structure and thus steering the link, changes in direction, lane changes and cornering of the motor vehicle can be effected. It is preferably provided that the operating element 1 is held on the handlebar and can therefore be pivoted with the handlebar, for example, about the steering axis relative to the supporting structure. In particular, it is conceivable that functions of the motor vehicle can be effected by means of the operating element 1, in particular by a person such as the driver of the motor vehicle.

The operating element 1 has a guide link 2 which has two link tracks 3 and 4 which cross one another. The guide link 2 is formed, for example, by a link element which is in particular also designed as a solid body. It is conceivable that the link tracks 3 and 4 are recesses such as slots in the link element. It can be seen that the link path 3, also referred to as the first link path, extends longitudinally and straight along a first straight line illustrated by a double arrow 5 and thus has a first direction of longitudinal extent, which is defined by the Dop pelarrow 5 is illustrated. The link path 4 , also referred to as the second link path, extends along a second straight line illustrated by a double arrow 6 elongate and thereby straight, so that the link path 4 has a second longitudinal extension direction illustrated by the double arrow 6 . The link tracks 3 and 4 run perpendicular to one another and intersect, in particular in their centers, so that the longitudinal directions of the link tracks 3 and 4 run perpendicular to one another. The link tracks 3 and 4 thus form a cross, so that the guide link 2 is also referred to as a cross link.

The operating element 1 has a first lever arm 7, which is also referred to as the first rotary arm. The first lever arm 7 is pivotably mounted about a first pivot axis 8 on a base element 9 of the operating element 1 and can thus be pivoted about the pivot axis 8 relative to the base element 9 in a first direction of rotation and in a second direction of rotation opposite to the first direction of rotation, i.e be pivoted or rotated. In particular, it is conceivable that the operating element 1 is held on the handlebar via the base element 9 .

The operating element 1 also has a second lever arm 10 which is mounted on the first lever arm 7 so that it can pivot about a second pivot axis 11 relative to the lever arm 7 . Out of 1 it can be seen that the pivot axes 8 and 11 are perpendicular to one another. In this case, the pivot axis 8 runs parallel to the first direction of longitudinal extent of the slideway 3 or coincides with the first direction of longitudinal extent of the slideway 3 . The pivot axis 11 runs parallel to the second direction of longitudinal extent of the link track 4 or coincides with the second direction of longitudinal extent of the link track 4 . In particular, it is conceivable that the lever arm 10 can also be pivoted about the pivot axis 8 relative to the base element 9 with the lever arm 7 . The pivot axis 11 runs parallel to the first direction of longitudinal extent of the first link track 3 or coincides with the first direction of longitudinal extent of the first link track 3 . Furthermore, the pivot axis 8 runs parallel to the second longitudinal direction of the second link track 4 or the pivot axis 8 coincides with the second longitudinal direction of the second link track 4!

The operating element 1 shows how particularly well in conjunction with 2 as can be seen, an operating lever 12, whose direction of longitudinal extent, also referred to as the longitudinal direction of the lever, is illustrated by a double arrow 13. Out of 1 and 2 It can be seen particularly well that the direction of longitudinal extension of the operating lever 12 illustrated by the double arrow 13 runs perpendicularly to the two pivot axes 8 and 11 . The operating lever 12 is also referred to as a joystick, operating stick or control stick. In other words, at the in the 1 and 2 shown, first embodiment, the pivot axes 8 and 11 in a common plane. To put it another way, a plane is spanned by the pivot axes 8 and 11, with the longitudinal extension direction of the operating lever 12 running perpendicular to the plane, at least in a 1 and 2 For example, the pivot axes 8 and 11 intersect at a point of intersection, it being preferably provided that the longitudinal direction of the operating lever 12 runs through the point of intersection. In other words, for example, a central axis 14 of the operating lever 12 runs through the point of intersection, the operating lever 12 for example being rotationally symmetrical with respect to the central axis 14 at least in a length region of the operating lever 12, in particular completely.

The operating lever 12 engages in the guide link 2 and is thereby guided by means of the guide link 2, in particular by means of the link tracks 3 and 4, which will be explained in more detail below. The operating lever 12 can be moved in a guided manner along the first link path 3 while the first lever arm 7 pivots about the first pivot axis 8 relative to the base element 9 .

In addition, the operating lever 12 can be moved in a guided manner along the second link path 4 while the second lever arm 10 pivots about the second pivot axis 11 relative to the first lever arm 7 . This means, for example, that the link tracks 3 and 4 allow movements of the operating lever 12 along the link tracks 3 and 4 and thereby relative to the link element in a link track plane in which the link tracks 3 and 4 extend, in particular via a respective first path, where, for example, the guide link 2 prevents all other movements of the control element 12 occurring in the plane of the slide track, so that the operating lever 12 in the plane of the slide track only along the slide tracks 3 and 4 or in the directions of movement specified or permitted by the slide tracks 3 and 4 and not in others Directions can be moved, or the guide link 2 limits all other movements of the operating lever 12 taking place in the slideway plane in such a way that the operating lever only over all other directions a second path that is smaller than the respective first path in the link track plane.

The operating element 1 also has a first torsion spring 15 which is supported on the first lever arm 7 and on the base element 9 at least indirectly, in the present case directly, in a supportable manner or in the present case. Furthermore, the operating element 1 comprises a second torsion spring 16, which is supported on the first lever arm 7 and on the second lever arm 10, in each case at least indirectly, in the present case directly, which can be supported. The lever arm 7 and with it the lever arm 10 and the operating lever 12 can be pivoted relative to the base element 9 about the pivot axis 8 in the first direction of rotation and the second direction of rotation opposite the first direction of rotation, i.e. pivoted or rotated. Furthermore, the lever arm 10 and with it, for example, the operating lever 12 can be rotated relative to the lever arm 7 about the pivot axis 11 in a third direction of rotation and in a fourth direction of rotation opposite the third direction of rotation, i.e. pivoted or pivoted. If the lever arm 7 is rotated in the first direction of rotation or in the second direction of rotation, in particular from an in 1 and 2 shown, first starting position of the lever arm 7 out, thereby the torsion spring 15 is tensioned. Provision is preferably made for the torsion spring 15 to be somewhat tensioned in the first starting position and thus in the first starting position to provide a spring force which acts in particular about the pivot axis 8 on the lever arm 7 and is also referred to as the first spring force. If the lever arm 10 is pivoted in the third direction of rotation or in the fourth direction of rotation relative to the lever arm 7 about the pivot axis 11, in particular from an in 1 and 2 shown, second starting position of the lever arm 10 out, so Fig. The torsion spring 16 is tensioned. It is preferably provided that the torsion spring 16 is slightly tensioned in the second starting position of the lever arm 10, so that the torsion spring 16 preferably provides a second spring force in the second starting position, which acts at least indirectly, in particular directly, about the pivot axis 11 on the lever arm 10. By means of the spring forces and thus by means of the torsion springs 15 and 16, when the lever arms 7 and 10 are deflected, i.e. pivoted out of their respective initial positions, they can be reset and thus moved back into their respective initial positions, whereby the following can be implemented in particular: If the Operating lever 12 from its in 1 and 2 shown zero position moves out along the respective link track 3 or 4, the lever arms 7 and 10 are pivoted accordingly. Thus, when the operating lever 12 is deflected, i.e. moved out of its zero position along the link tracks 3 and 4, it can be reset by means of the spring forces and thus by means of the torsion springs 15 and 16 and thus moved back into its zero position and, in particular, held in the zero position become. As a result, a particularly advantageous operation of the operating element 1, which is particularly haptically particularly high-quality, can be represented.

Particularly good looking 1 it can be seen that the first lever arm 7 has a first length range L1 and a second length range L2. The length region L1 has a third direction of longitudinal extension, which, at least in the first starting position of the lever arm 7 , runs parallel to the second direction of longitudinal extension of the link track 4 . The length region L2 has a fourth direction of longitudinal extension, which, at least in the first starting position of the lever arm 7 , runs parallel to the first direction of longitudinal extension of the link track 3 . At the in 1 and 2 In the first embodiment shown, the third direction of longitudinal extension of length region L1 runs perpendicular to the fourth direction of longitudinal extension of length region L2. The lever arm 7 has a third length region L3 with a fifth direction of longitudinal extent, which runs parallel to the first direction of longitudinal extent. It can be seen that the lever arm 7 is pivotably mounted on the base element 9 over its length region L3, and the lever arm 10 is pivotably mounted on the length region L1 of the lever arm 7. As a result, a particularly compact design of the operating element 1 can be implemented while at the same time realizing a high-quality haptic actuation and thus operability of the operating element 1.

In 1 a first bearing, by means of which the lever arm 7 is mounted on the base element 9 so as to be pivotable about the pivot axis 8, is denoted by 17. In this case, the first bearing 17 is designed, for example, as a sliding bearing, which is also known as a sliding partner and is preferably formed from a metallic material. In addition, 1 a second bearing, by means of which the lever arm 10 is mounted about the pivot axis 11 on the lever arm 7, is denoted by 18. It is conceivable that the bearing 18 is a sliding bearing, which is also formed from a metallic material. It is also conceivable that the bearing 17 and/or 18 is a roller bearing, which comprises, for example, a roller bearing, in particular a ball bearing, by means of which the lever arm 7 is pivotably mounted on the base element 9 or lever arm 10 on the lever arm 7. As a result, operation of the operating element 1 that is particularly advantageous in terms of haptics can be ensured.

Furthermore, it is provided in the first embodiment that the operating lever 12 is held on the second lever arm 10 in a displaceable manner along the direction in which it extends in the longitudinal direction of the lever illustrated by the double arrow 13 . Thus, for example, a person can touch the operating lever 12 with their finger and thereby exert a force on the operating lever in order to thereby move the operating lever along the respective link path 3 or 4 . The operating lever 12 thus serves as the main point of contact for the person, in particular for the person's finger. The guide link 2, designed here as a cross link, ensures a clear, precise guidance of the operating lever 12 along the link path 3 and, for example, in relation to the image plane of FIG 1 to the left and right and along the slide track 4 and related to the image plane of 1 up and down. For example, the torsion spring 16 is arranged on the lever arm 10, which is formed, for example, by a bolt. Alternatively or additionally, for example, the torsion spring 15 is arranged on the lever arm 7 .

In addition, the person can, for example, use their finger to exert a force running along the direction of longitudinal extension of operating lever 12 on operating lever 12 and thereby move operating lever 12 along its direction of longitudinal extension relative to lever arms 7 and 10, in particular in a first actuation direction illustrated by arrow 19 . For example, an in 1 and 2 not shown spring element is provided, which is tensioned when the operating lever 12 is displaced in the first direction of actuation relative to the lever arms 7 and 10. In this way, the spring element provides a third spring force, by means of which, particularly when the person releases the operating lever 12, the operating lever 12 moves relative to the lever arms 7 and 10 along the direction of the longitudinal extent of the lever and in the process in a second actuation direction illustrated by an arrow 20, wherein the second direction of actuation is opposite to the first direction of actuation.

In this case, the operating element 1 has a 2 recognizable guide element 21, for example an additional setting or guide link provided in addition to the guide link 2, forms or provides. The guide element 21 allows the operating lever 12 to be displaced along the longitudinal direction of the lever extension of the operating lever 12 and in particular in the first actuation direction relative to the lever arms 7 and 10 only in its rest position, also referred to as the rest position, into which the operating lever 12 can be moved by means of the torsion springs 15 and 16 is movable, that is resettable. For this purpose, for example, the guide element 21 has a recess 22 . The operating lever 12 is, for example, only in its zero position in such an overlap with the recess 22 that the operating lever 12 can only be displaced in the zero position in the first actuation direction and thereby moved into the recess 22, so that only in the zero position of the operating lever 12 the operating lever 12 can be displaced relative to the lever arm 7 and 10 in the first direction of actuation. In all other positions into which the operating lever 12 can be moved along the link tracks 3 and 4, the guide element 21 prevents the operating lever 12 from being displaced relative to the lever arms 7 and 10 in the first actuation direction, so that the operating lever 12 can be moved in all other positions , In which the operating lever 12 can be moved along the link tracks 3 and 4, can not be moved in the first direction of actuation relative to the lever arms 7 and 10. This ensures particularly advantageous operation of the operating element 1 .

3 until 6 show a second embodiment of the operating element 1. In 3 The spring element designed as a mechanical spring and labeled 23 can be seen, by means of which, when the operating lever 12 is in its zero position and has been displaced in the first operating direction relative to the lever arms 7 and 10 and is then released, for example by a person, in the second direction of actuation is shifted relative to the lever arms 7 and 10 and is thus pushed back into its zero position. For example, operating lever 12 can be shifted from an unactuated position to an actuated position relative to lever arms 7 and 10 in the first actuation direction, which runs parallel to the longitudinal direction of the lever or coincides with the direction of longitudinal extent of the lever, if and only if the operating lever 12 is in its zero position , which is ensured by the guide element 21. In the actuated position, the spring element 23 is tensioned, in particular more tensioned than in the non-actuated position of the operating lever 12, so that when the operating lever 12 is in the actuated position, the spring element 23 provides a third spring force that acts in the second actuation direction and at least indirectly, in particular directly , acts on the operating lever 12. The operating lever 12 can be moved from the actuated position into the unactuated position by means of the third spring force and can thus be displaced relative to the lever arms 7 and 10 .

Out of 3 it can be seen that the spring element 23 is designed, for example, as a helical spring. In particular, it is conceivable that the spring element 23 along the lever longitudinal first stre ckungsrichtung the operating lever 12 on the one hand on the operating lever 12 and on the other hand on the lever arm 10 at least indirectly, in particular directly, can be supported or is supported.

Out of 4 it can be seen that the recess 22 of the guide element 21 can be designed as a through opening. For example, the guide element 21 is formed in one piece with the base element 9 . Furthermore, it is conceivable for the guide element 21 and the base element 9 to be components which are formed separately from one another and are connected to one another, in particular and movably.

The control element 1 preferably comprises a so-called haptic element, which can be integrated into the guide element 21, for example. When the operating lever 12 reaches its actuated position, the haptic element causes haptic feedback that can be felt by the person operating the operating lever 12, whereby the person receives haptic feedback that the operating lever 12 has reached its actuated position. For example, an electrical contact is closed by moving the operating lever 12 from the unactuated position to the actuated position, so that the haptic element haptically reports back the closing of the electrical contact. This takes place, for example, in the following way: If the operating lever 12 is moved from its inactive position to its actuated position, i.e. in the first operating direction relative to the lever arms 7 and 10, the haptic element, which thereby causes the movement of the operating lever 12 in The force counteracting the actuated position and generated or provided by means of the haptic element, for example, and also referred to as a counterforce, increases, in particular at least essentially continuously or constantly, until the actuated position is reached and falls again, in particular suddenly, when the actuated position is reached, so that the haptic Feedback that haptically reports that the actuated position has been reached, that is to say communicated, by the person operating the operating lever 12 as a snap, that is to say as a snap, as when a clicker is actuated. This is realized, for example, in that when the operating lever is moved from its non-actuated position to its actuated position, a spring-loaded ball, in particular of the haptic element, is moved along a ramp, in particular of the haptic element, the ball being moved when the actuated position is reached is moved into a corresponding receptacle, for example by means of a spring, and thereby snaps into the receptacle. Thus, the spring is initially tensioned, which causes the above-mentioned increase in force. When the ball snaps into the corresponding receptacle, the counterforce drops, in particular abruptly or suddenly, as a result of which the said snap, ie the drop in the counterforce, is brought about. The operating lever 12 is reset, ie the operating lever 12 is moved back into the non-actuated position, by means of the third spring force, ie by means of the spring element 23 . A particularly high-quality haptic operation of the operating element 1 can thereby be ensured.
