Description

Technical Field

[0001] The present invention relates to a handle unit for a vehicle, an opening component having electric and mechanical opening mechanisms, and a method for operating the handle unit to open the vehicle opening component when the electric opening function fails. Background Technology

[0002] Electric opening mechanisms for vehicle doors are known in the prior art. Vehicle doors are automatically unlocked and / or opened via electric opening mechanisms.

[0003] To allow access to the vehicle even in the event of a malfunction in the electric opening mechanism (e.g., due to a vehicle accident), a mechanical opening mechanism is typically provided, which can be manually operated in the event of a malfunction. For example, rescue personnel can operate the mechanical opening mechanism. For instance, a door handle is known from DE102017123258A1, in which, to activate the mechanical opening mechanism, a spring must be pressed to overcome the reaction force. To finally move the door handle back to its original position, the spring must be pressed again.

[0004] Besides being used in the event of an accident, the mechanical opening mechanism can also be activated in the event of other malfunctions, such as a temporary failure of the electric opening mechanism control. This can cause irritation and / or discomfort if the user needs to exert significant force to reset the handle or if the return spring force needs to be increased. In the worst-case scenario, the handle may also become stuck in its operating position, particularly due to the need for high return force, making it impossible for the door to close. Summary of the Invention

[0005] The object of this invention is to at least partially eliminate the aforementioned disadvantages known in the prior art. Specifically, the object of this invention is to improve the emergency opening capability of the vehicle's opening mechanism and enhance safety, preferably by simplifying the reset of the handle.

[0006] The aforementioned objective is achieved by a handle unit having the features of claim 1, an opening member having the features of claim 14, and a method having the features of claim 15. Further features and details of the invention derive from their respective features and details. Dependent claims, description, and drawings. The features and details described in conjunction with the handle unit according to the invention naturally also apply to the opening member according to the invention and / or the method according to the invention, and vice versa; therefore, reference should always be made to each other disclosure relating to various aspects of the invention.

[0007] According to a first aspect of the invention, there is a handle unit for a vehicle. The handle unit has a handle for opening a vehicle opening component, which is movable at least between an actuated position for activating an electrically operated opening function for opening the opening component and an emergency opening position for mechanically opening the opening component. Furthermore, the handle unit has a rotating element designed to rotate (also implying pivoting) about a preferred rotation axis or pivot track when the handle is moved from the actuated position to the emergency opening position. Thus, the rotating element can also pivot along a pivot track. The handle component further includes a reaction force element for applying a reaction force to the rotating element when the handle is moved from the actuated position to the emergency opening position. The rotating element and the reaction force element form a contact pair having at least a contact area that can be brought into a resistance position where a reaction force from the reaction force element can act on the rotating element. Additionally, the contact area can be brought into a release position where the reaction force element can be overcome during handle movement from the actuated position to the emergency opening position. Alternatively, the reaction element may have a movable bearing for the reaction element to move in at least one return direction, thereby enabling the reaction element to be overcome from the emergency opening position when the handle returns to its original position via the rotating element, particularly in the actuation position direction and / or in the rest position direction, especially when the contact area is in a resistance position.

[0008] To mechanically open the opening mechanism, the handle can be connected to a Bowden wire, through which the mechanical opening mechanism can be actuated. For example, the handle and / or rotating element may have an actuation interface for connecting to the Bowden wire. To activate the opening function, the handle, particularly in the actuated position, can be connected to or operably connected to an electro-actuated element, such as a microswitch or a proximity sensor. In the actuated position, the actuated element can be actuated or can be actuated. It can be specified that when the handle is in the actuated position, the electrical switch of the actuated element is closed. However, it is also conceivable that when the handle is in the operating position and a user approaches, the proximity sensor can be activated. The handle can be a pull handle and / or a flip handle.

[0009] The axis of rotation is, in particular, the geometric axis. The pivoting track can be achieved via an arcuate guide to generate the pivoting motion of the rotating element. The rotating element may include, for example, a mass counterweight. Preferably, the rotating element is connected to the handle, particularly integrally. However, it is also conceivable that the rotating element is operably connected to the handle via a gear, for example, a lever mechanism, so that the handle rotates about the axis of rotation when moved from the actuated position to the emergency open position. The rotating element can be mounted on a handle bracket of the handle unit. For example, the handle unit can be attached to the opening component via the handle bracket.

[0010] The reaction force can particularly counteract the actuating force, which preferably depends on the actuation of the handle on the rotating element. The reaction force when the handle is moved from the actuated position to the emergency open position can be applied to the rotating element via the reaction force element, at least in the moving portion of the rotating element and / or the handle. The contact area is specifically designed for force transmission between the reaction force element and the rotating element. This contact pair is specifically designed to create a force-locking connection and / or form-locking connection in at least one moving portion when the handle is moved from the actuated position to the emergency open position. The contact pair includes contact areas and preferably includes opposing contact areas. For example, the contact areas can be formed on the reaction force element and the reaction force area can be formed on the rotating element, or vice versa. However, it is also conceivable that both the reaction force element and the rotating element have contact areas adjustable between a resistance position and a release position.

[0011] The reaction element can be advantageously designed like a lever. The reaction element can be mounted via bearings on, for example, a handle bracket, particularly for applying a reaction force. The bearings of the reaction element can be designed for translational and / or rotational mounting of the reaction element. For example, the bearing assembly can include sliding bearings and / or rolling element bearings.

[0012] The contact area can move and / or change its external shape between a resistance position and a release position. It can be specified that the contact area is preloaded to the resistance position such that when the handle is moved from the actuation position to the emergency open position, the contact area is brought into the release position, and when the handle is opened, the contact area automatically returns to the resistance position. The reaction force element and the rotating element are separated from each other, i.e., force-locking and / or form-locking connections between the contact pairs are eliminated.

[0013] Due to the movable bearing mounting, the reaction force element can bypass the rotating element when the handle returns to its original position. Therefore, when the handle returns from the emergency open position, the reaction force element applies a reduced reaction force, specifically to the rotating element. As a result, for example, the size of the handle's return unit can be smaller, which in particular improves the feel when moving the handle from the actuated position to the emergency open position, as the actuation force counteracts the lower return force. If the handle is manually moved back, the manual return force may be reduced. When the handle is moved to the emergency open position, the reaction force element can be loaded along the actuation direction, where the return direction is specifically oriented opposite to the actuation direction. Therefore, the possibility of emergency opening of the opening mechanism is improved through a simplified handle reset. By smoothing the force curve when moving the handle back from the emergency open position, the loss of comfort when the electric opening mechanism malfunctions is reduced. This also ensures that the handle does not remain in its emergency open position, thus improving safety.

[0014] Furthermore, in the handle unit according to the invention, it is conceivable that the pivot bearing of the rotating element and the bearing of the reaction element have a bearing distance from each other, and that when the handle moves back from the emergency open position, the reaction element and the rotating element contact each other in the first moving portion and separate from each other in the second moving portion. The pivot bearing is specifically designed to rotatably support the rotating element about a rotation axis. The bearing distance enables the first and second moving portions. For example, when the handle is moved between the emergency open position and the actuated position and / or vice versa, the rotating element and the reaction element can each perform at least a partial circular motion that overlaps in the first moving segment. In the second moving portion, the circular motions can be performed separately from each other. In particular, a force-locking and / or form-locking connection between the rotating element and the reaction element is eliminated in the second moving portion. For example, if the pivot bearing and the movable bearing are securely fixed to the handle bracket, the bearing distance can be constant. However, it is also conceivable that the bearing distance changes when the handle moves. For example, the movable bearing can be guided in a linkage guide, thereby changing the bearing distance when the handle moves and / or returns. The first moving part is specifically defined by the bearing distance, the length of the rotating element, and the length of the reaction force element. Therefore, the return movement of the handle can be cleverly set or adjusted for the movement process.

[0015] Within the scope of this invention, it is also conceivable that the contact area is designed to be deformable, such that when the handle unit is moved from the actuated position to the emergency open position, the reaction force element is overcome by the rotational element through deformation of the contact area. The contact area can, for example, be used to overcome the reaction force by being pressed down. Furthermore, it is conceivable that the contact area is at least partially compressed to reach the release position. This deformation can create a degree of freedom of movement for the relative contact areas of the contact pair, allowing the relative contact areas to pass through the contact area.

[0016] It is also conceivable that, in the handle unit according to the invention, the contact area is designed to be elastic for automatically returning from the release position to the resistance position. Preferably, the contact area is elastically deformable to move from the resistance position to the release position. Thus, the contact area can return to its original shape during the return movement from the release position to the resistance position. The automatic return movement can occur, in particular, after the reaction force and / or the reaction force element has been overcome by the rotating element. It can be specified that the contact area has a deformable shape. For example, the contact area can include metal, preferably in the form of a metal sheet. However, it is also conceivable that the contact area includes plastic, particularly soft parts and / or foam. Because the contact area itself is designed to be elastic, for example, an additional return spring for the return movement can be omitted. Alternatively or concurrently, the contact area can be movable and prestressed or prestressed to the resistance position by means of an elastic element.

[0017] Furthermore, in the handle unit according to the invention, it can be advantageously specified that the contact area comprises a spring, particularly a leaf spring. Preferably, the contact area can be formed by a spring. For example, the reaction force element can have a rigid reaction body on which the spring and a movable bearing are arranged. The spring is particularly a cost-effective component, and furthermore, the force curve of the reaction force when the handle is moved can be defined by or can be defined by the spring. By adjusting the spring force, the reaction force can be adjusted to obtain a comfortable feel.

[0018] Furthermore, in the handle unit according to the invention, it is conceivable that the contact area has a first end, on which the contact area is attached to the rotating element and / or the reaction force element, and a second end, which is used to overcome the contact area not being fixed when the handle is moved from the actuated position to the emergency open position. Since the contact area is fixed only at the first end, a floating and / or sliding installation of the second end can be achieved. Therefore, the second end can be movable, while the first end is fixed. It can be configured such that the second end rests loosely on the rotating body of the rotating element or the reaction body of the reaction force element, and is guided by the rotating body or the reaction body when the contact area moves from the resistance position to the release position or vice versa. As a result, the contact area at the second end can have a degree of freedom of movement, which facilitates elastic deformation of the contact area. Therefore, the contact area can be moved at least partially to the release position, whereby the adjustment path of the contact area can be extended without any, particularly significant, plastic deformation of the contact area.

[0019] It is also conceivable that, in the handle unit according to the invention, the contact pair has particularly rigid relative contact areas for contacting the contact areas in a resistance position, preferably wherein the relative contact areas have a control profile for changing the force curve of the reaction force when the handle is moved from the actuated position to the emergency open position. The control profile can, for example, determine the contact point when the handle is moved from the actuated position to the emergency open position. Furthermore, the force change process formed by the control curve when the handle is moved from the operating position to the emergency open position can be adjusted for the user's tactile sensation. For example, the control curve may include a steep slope to apply the reaction force.

[0020] Furthermore, in the handle unit according to the invention, the opposing contact area and / or the contact area may advantageously be provided with a control cam for increasing the reaction force as the handle moves from the actuated position to the emergency open position. For example, the control profile may include an arcuate portion from which the control cam protrudes. The control cam can be pushed downwards into the contact area to move the contact area from a resistance state to a release state. After the control cam passes the contact area, the contact area can return to the resistance state, particularly by springing back.

[0021] Preferably, in the case of the handle unit according to the invention, the movable bearing of the reaction force element is designed as a support for the reaction force element to rotatably about a bearing axis parallel to the axis of rotation. The bearing axis is preferably a geometric axis. Therefore, the contact area and the relative contact area can move at least partially on a circular track. The contact pair preferably has an overlapping movement phase that generates the reaction force. In the area where the circular tracks do not overlap, the contact of the contact pair can be canceled. This allows for advantageous motion characteristics of the temporary reaction force when the handle is moved from the operating position to the rest position.

[0022] Furthermore, the handle unit according to the invention can advantageously be provided with a blocking element designed to block the reaction force element in a return direction opposite to the actuation direction, particularly when the handle (11) is moved from the actuation position to the emergency open position, the reaction force element is designed to rest on the blocking element. The actuation direction can also be specifically referred to as the loading direction. The return direction can be oriented such that the reaction force element moves away from the blocking element when moving in the return direction. The blocking element can, for example, be attached to the handle bracket of the handle unit, and / or integrated into the handle bracket of the handle unit. The reaction force element can be considered as a resistance in the form of a mechanical block. The blocking element restricts the movement of the reaction force element in the return direction, whereby the reaction force can be applied as a supporting force. For example, this causes deformation of the contact area when the handle moves further against the reaction force. Since the blocking element only works in the return direction, the reaction force element can avoid the rotating element when the handle is returned from the emergency open position to the actuation position.

[0023] Preferably, in the handle unit according to the invention, a preload unit may be provided for preloading the reaction force element in the actuation direction. The preload unit may include a spring, preferably in the form of a torsion spring, for preloading the reaction force element around the bearing axis. The reaction force element is thus specifically pressed against the blocking element. When the handle returns from the emergency open position to the actuated position, the preload unit thus preferably counteracts the movement of the handle. It can be specified that the preload unit has a low spring force if there is no additional external force on the reaction force element, particularly in the second movement portion. After the reaction force element avoids the rotating element, the preload unit allows the reaction force element to return to the blocking element. This allows for repeated emergency open processes, particularly without requiring maintenance of the handle unit.

[0024] Within the scope of this invention, it is also conceivable that the handle can be brought to an unacted rest position, and that the handle can be brought from the rest position to an actuated position to an emergency opening position. For example, the actuating element can be actuated by moving the handle from the rest position to the actuated position. It can be specified that the movement of the handle from the rest position to the actuated position occurs along a short stroke distance, particularly about 4° or exactly 4° around the handle axis. The handle axis can advantageously be the axis of rotation of the rotating element or another axis parallel to the axis of rotation. It can be specified that the handle in the rest position is flush with, particularly flush with, the outer surface of the opening component. This can improve the appearance and / or aerodynamic performance of the opening component with the handle. By moving from the rest position to the actuated position, the user's actuation action is made possible to actuate the electric opening mechanism in normal operation. The reaction force provides tactile feedback to the user, particularly through the actuation of the electric opening mechanism. If the electric opening mechanism is unresponsive due to a malfunction, the user can apply the reaction force to operate the mechanical opening mechanism.

[0025] Within the scope of this invention, it is also conceivable to provide a reset unit for pre-tensioning the handle in a rest position and / or an actuated position. The reset unit may comprise a spring, particularly a torsion spring. Preferably, the reset unit can apply a greater spring force and / or a greater restoring torque compared to the pre-tensioning unit. This allows the handle to easily enter the rest position and / or operating position. Therefore, even after an emergency opening, the original functional state of the handle unit can be restored, which, for example, allows the vehicle to continue operating. Furthermore, improved comfort can be achieved, particularly for outward-opening handles, which would otherwise require considerable effort from the user to release from the emergency-opening position.

[0026] According to another aspect of the invention, an opening member is provided. The opening member has an electric opening mechanism for an electric opening function of the opening member, a mechanical opening mechanism for mechanically opening the opening member (2), and a handle unit according to any one of the preceding claims.

[0027] Therefore, the opening component according to the invention provides the same advantages as those already described in detail with reference to the handle unit according to the invention. The opening component can be, for example, a vehicle door and / or a flip cover. The vehicle can be, for example, a motor vehicle and / or an aircraft. A mechanical opening mechanism can, for example, include a mechanical transmission element, such as a Bowden wire, for actuating a locking unit to lock and / or unlock the opening component. An electric opening mechanism can have an electric actuation element, such as an electric actuation element in the form of a microswitch, a proximity sensor, and / or a touch sensor. Furthermore, the electric opening mechanism can include a servo motor for actuating the locking unit to lock and / or unlock the opening component. Additionally, it is conceivable that the electric opening mechanism has an actuator for the automatic opening and / or closing movement of the opening component. Furthermore, the opening component can have a control unit for, for example, using an ID transmitter to verify a user's authentication process.

[0028] According to another aspect of the present invention, a method is provided for operating a handle unit, particularly a handle unit according to the present invention, for opening the opening component of a vehicle in the event of a malfunction in the electric opening mechanism, comprising the following steps:

[0029] - The handle of the handle unit is moved from the actuation position for activating the electric opening function to the emergency opening position for mechanically opening the opening component (2). When the movement moves from the actuation position to the emergency opening position, the reaction force is overcome by being carried from the resistance position to the release position through the contact area. In the resistance position, the reaction force from the reaction force element of the handle unit can be applied to the rotating element of the handle unit.

[0030] The return motion of the handle from the emergency open position, wherein the reaction force element moves along at least one return direction, such that the rotating element overcomes the reaction force element, and the contact area is in the resistance position.

[0031] Therefore, the method according to the invention brings the same advantages as those already described in detail with reference to the handle unit and / or the opening component according to the invention. It can be specified that the reaction force is applied directly in the actuated position and / or in the subsequent movement between the actuated position and the emergency opening position. The return movement of the handle can preferably be performed automatically. It can also be specified that the handle is moved from the rest position to the operating position before being moved from the operating position to the emergency opening position, particularly by pivoting the handle approximately or exactly 4°. (See accompanying drawings)

[0032] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the accompanying drawings. Features mentioned in the claims and specification may be essential to the invention individually or in any combination. The invention is schematically illustrated in:

[0037] Figure 5 The force curve during the motion process is displayed.

[0038] In the following description of some exemplary embodiments of the present invention, the same reference numerals are used for the same technical features in different exemplary embodiments. Detailed Description

[0039] Figure 1 A handle unit 10 for a vehicle 1 according to the invention is shown in a first exemplary embodiment. According to the invention, the handle unit 10 is arranged on the opening member 2. Figure 2 As shown, the opening component 2 is, for example, a door of vehicle 1. The opening component 2 includes an electric opening mechanism 3 for electric opening and a mechanical opening mechanism 4 for mechanically opening the component. The electric opening mechanism 3 and the mechanical opening mechanism 4 are also operatively connected to a locking unit 5 for locking and / or unlocking the opening component 2. For this purpose, the mechanical opening mechanism 4 specifically has a mechanical transmission element, such as a Bowden wire, for actuating the locking unit 5. The electric opening mechanism 3 may have an electric actuation element in the form of, for example, a microswitch, a proximity sensor, and / or a touch sensor, thereby controlling the electric actuator for actuating the locking unit 5.

[0040] The handle unit 10 also includes a handle 11 for opening the opening member 2 of the vehicle 1. For example... Figure 1 As shown, handle 11 can be a pull handle. However, it is also conceivable that handle 11 is an outward-opening handle. Handle 11 is in... Figure 1The handle 11 is in the unactuated rest position 11.1, where it rests on the outer surface of the opening member 2. Specifically, if the handle 11 is an outward-opening handle, it can be flush with the outer surface. The handle 11 can also move from the rest position 11.1 to the actuated position 11.2 for activating the electric opening function via the electric opening mechanism 3, and to the emergency opening position 11.3 for mechanically opening the opening member 2 via the mechanical opening mechanism 4. The emergency opening position 11.3 allows the user to mechanically open the opening member 2 in case the electric opening mechanism 3 fails. The emergency opening position 11.3 is only accessible from the actuated position 11.2. Due to the mobility of the handle 11 from the rest position 11.1 to the actuated position 11.2, the user can enter the vehicle 1, particularly relying solely on manual operation. In this case, the electric opening mechanism 3 can advantageously include a microswitch that is activated when the actuated position 11.2 is reached. If the electric opening mechanism 3 includes, for example, a proximity sensor, it is also conceivable that the rest position 11.1 can be omitted and the handle 11 can only move between the actuated position 11.2 and the emergency opening position 11.3.

[0041] To achieve a comfortable force curve during emergency opening, the handle unit 10 has a rotating element 20 designed to rotate about a rotation axis 20.1 when the handle 11 moves from the actuated position 11.2 to the emergency opening position 11.3 in the rotation direction 210.1. The rotating element 20 is preferably rigidly connected to the handle 11. Specifically, the rotating element 20 may include a flywheel for the handle 11. However, it is also conceivable that the rotating element 20 is connected to the handle 11 via a connecting gear 15, as... Figure 1 As shown. The connecting gear 15 may include, for example, a lever and / or a connector. Furthermore, the handle unit 10 includes a reaction force element 30 for applying a reaction force 201 to the rotating element 20 when the handle 11 moves 101 from the actuated position 11.2 to the emergency opening position 11.3. The rotating element 20 and the reaction force element 30 are preferably mounted on the handle bracket 14 of the handle unit 10.

[0042] Figure 4 The method steps of method 100 according to the present invention are shown, which is used to operate handle unit 10 to open opening component 2 in the event of a malfunction of the electric opening function. The sequence of motion of rotating element 20 and reaction force element 30 in method 100 is as follows: Figures 3a to 3eAs shown, the rotating element 20 and the reaction element 30 form a contact pair 40. When the rotating element 20 and the reaction element 30 are in contact, the reaction force 201 can be transmitted from the reaction element 30 to the handle 11 through the contact pair 40 via the rotating element 20. As a result, the user experiences tactile feedback in the form of resistance when operating the handle 11. Specifically, the feedback during normal operation indicates to the user, in a tactile manner, that the actuation position 11.2 has been reached. Figure 3a The rotating element 20 and the reaction element 30 are shown when the handle 11 is in the rest position 11.1. If the handle 11 moves, the reaction element 30 and the rotating element 20 each move on their respective circular track portions. For this purpose, the rotating element 20 has a rotary bearing 22 for supporting the rotating element 20 about a rotation axis 20.1, and the reaction element 30 has a movable bearing 31 for rotatably mounting the reaction element 30 about a bearing axis 30.1 parallel to the rotation axis 20.1. The pivot bearing 22 and the movable bearing 31 of the reaction element 30 also have a bearing distance 13 between them, through which their circular tracks intersect in some areas.

[0043] Figure 3b The diagram shows the rotating element 20 and the reaction element 30 when the handle 11 is in the actuated position 11.2, wherein the rotating element 20 and the reaction element 30 are engaged with each other. However, it is also conceivable that the actuated position 11.2 is reached only after the handle 11 has moved further in the direction of the emergency opening position 11.3. Figure 3b The position shown. In this case, the user receives tactile feedback only after the electric opening mechanism 3 has been activated. To apply the reaction force 201, the contact pair 40 (here, the reaction force element 30) has at least one contact area 41, which is in the resistance position 40.1, according to Figure 3b In the actuated position 11.2, the reaction force 201 is an applicable force from the reaction force element 30 to the rotating element 20. To apply the reaction force 201, the handle unit 10 also has a blocking element 43 for blocking the reaction force element 30 along the actuation direction 210. When the handle 11 moves 101 from the actuated position 11.2 to the emergency opening position 11.3, the reaction force element 30 rests on the blocking element 43, thereby supporting the reaction force element 30.

[0044] Furthermore, the contact pair 40 (here, the rotating element 20) has a rigid relative contact area 42 to contact the contact area 41 in the resistance position 40.1. The relative contact area 42 includes a control cam of control profile 42.1 for increasing the reaction force 201 when the handle 11 moves 101 from the actuated position 11.2 to the emergency opening position 11.3. Figure 5The graph shows the first force curve 202 as the handle 11 moves 101 from the operating position 11.2 to the emergency opening position 11.3, where the opening angle 200.1 of the handle 11 is plotted relative to the force 200.2. Figure 3b When the control cam strikes the contact area 41, the reaction force 201 forms a force peak in the first force curve 202 for tactile feedback.

[0045] Therefore, when the handle 11 is moved 101 from the actuated position 11.2 to the emergency opening position 11.3, the reaction force element 30 with reaction force 201 can be overcome by the rotating element 20, and the contact area 41 is also in the release area 40.2, which is as follows: Figure 3c As shown. Therefore, the contact area 41 is elastically deformable. As a result, when the handle 11 moves 101 from the actuated position 11.2 to the emergency open position 11.3, the contact area 41 is at least partially pushed downwards, especially if the user increases its braking force against the reaction force 201. Advantageously, the contact area 41 may include a spring, particularly a leaf spring. To improve the flexibility of the contact area 41, it may be slidably supported. Specifically, the first end 41.1 of the contact area 41 is attached to the reaction force element 30, while the second end 41.2 is not fixed. For example, the second end 41.2 may rest against the support area of ​​the reaction force element 30.

[0046] Emergency opening location 11.3 (as shown) Figure 3d As shown, the rotating element 20 pivots in the rotation direction 210.1 to actuate the mechanical opening mechanism 4. For example, the rotating element 20 may include a Bowden cable operating interface 23 for the mechanical opening mechanism 4. Due to the elastic configuration of the contact area 41, once the contact of the contact pair 40 is eliminated, the contact area 41 automatically enters the resistance position 40.1.

[0047] like Figure 3eAs shown, the handle 11 is then moved 102 from the emergency open position 11.3 back to the actuated position 11.2. The rotating element 20 moves from the emergency open position 11.3 in the direction of actuated position 11.2 and / or rest position 11.1 in the opposite direction of rotation 210.1. As a result, the control cam encounters the contact area 41 located in the resistance position 40.1 again in the first stage of movement 221. Due to the movable bearing 31 of the reaction element 30, the reaction element 30 is moved away from the blocking element 43 and moves in at least one return direction 211 opposite to the actuation direction 210. Specifically, the reaction element 30 rotates about the bearing axis 30.1 in the return direction 211. As the reaction element 30 and the rotating element 20 move further on their respective circular track portions, the contact separates from each other in the second moving portion 222. The circular track is specifically defined by the bearing distance 13 between the pivot bearing 22 of the rotating element 20 and the movable bearing 31 of the reaction element 30.

[0048] Preferably, the reaction force element 30 is pre-tightened by the pre-tightening unit 44 in the actuation direction 210 along the direction of the blocking element 43, thereby automatically returning the reaction force element 30 to its initial position when the reaction force element 30 is released from the rotating element 20 during the return movement 102 of the handle 11. For automatic return of the handle 11 and / or the rotating element 20, a reset unit 12 can be provided to pre-tighten the handle 11 to the rest position 11.1 and / or the actuation position 11.2.

[0049] Because of the movable bearing 31, when the handle 11 moves 102 from the emergency open position 11.3 back to the actuated position 11.2 and / or the rest position 11.1, the reaction force element 30 applies only a reduced reaction force 201 to the rotating element 20, such as... Figure 5 As shown, the second force curve 203 becomes clear when the handle 11 returns to its original position 102. As a result, for example, the size of the reset unit 12 of the handle 11 can be smaller, thereby particularly improving the tactile feedback when the handle 11 moves from the actuated position 11.2 to the emergency opening position 11.3, since the actuating force counteracts the lower restoring force. In particular, this reduces the loss of comfort in the event of a malfunction of the electric opening mechanism 3.
