Technical Field

[0002] This invention relates to an improved solution for a door lock actuator for motor vehicle doors, and more particularly to an improved solution for actuating a motor vehicle door lock from the inside. Background Technology

[0003] In the prior art, the interior door handle 6Q0837174 of the Volkswagen Polo IV is known ( Figure 2 This interior door handle combines the interior door handle and door lock actuator into a single module. While it offers an attractive appearance and is relatively compact, the inventors have set their sights on further improving the module. Summary of the Invention

[0004] The objective of this invention is achieved through the independent claims. Advantageous improvements are defined in the dependent claims.

[0005] In particular, the objective of this invention is achieved through a side door of a motor vehicle, wherein the side door has:

[0006] A door lock actuator for a door lock, wherein the door lock actuator is preferably an interior door actuator, and wherein the door lock actuator has a pivot rod that can be mounted to pivot about a rotation axis of a hinge, wherein the pivot rod has a coupling section for a mechanical actuation device for the door lock, the mechanical actuation device being coupled to the coupling section in the installed state.

[0007] Furthermore, the object of the present invention is achieved, in particular, by the door lock actuator described herein.

[0008] Furthermore, the object of the present invention is achieved in particular by means of a module for the side door of a motor vehicle, the module comprising a door lock actuator described herein and an inner door handle described herein.

[0009] Furthermore, the object of the present invention is achieved, in particular, by applying the module according to the invention to the side door of a motor vehicle or to the door lock actuator of the invention.

[0010] In another embodiment of the invention, the side door has:

[0011] An interior door handle (or door handle) having one or more fastening areas and at least one gripping area that can be gripped by hand from behind, preferably with a fully 360° circumferential gripping capability, wherein the gripping area has an axial extension; wherein the pivot rod is integrated into the gripping area of ​​the interior door handle, wherein the axis of rotation is oriented substantially transversely to the axial extension.

[0012] The axial extension transverse to the gripping area, particularly the orientation of the pivot axis of the pivot rod (uncommon in passenger cars), allows the pivot rod to be integrated directly into the gripping area of ​​the interior door handle in a space-saving manner, rather than on top of it, while simultaneously achieving a long lever arm. Thus, a configuration is obtained that saves more space while maintaining optimal functionality.

[0013] The motor vehicle is preferably a passenger car. In the following text, a vehicle coordinate system is partially referenced, in which the X direction points forward in the direction of travel, the Z direction points upward, and the Y direction extends laterally from the front passenger towards the driver in the X direction.

[0014] An actuated door lock can be understood as, for example, opening / closing a door latch and / or locking / unlocking it.

[0015] The mechanical actuation device preferably allows the door lock to have a purely mechanical actuation option, through which the door lock can be unlocked and / or the latch can be opened, thereby allowing the door to pivot open. The door lock actuator is preferably designed to perform mechanical actuation in the absence of any power, so that this type of actuation can be used in emergency situations where there is no onboard power. The mechanical actuation device, for example, has Bowden cables and / or mechanisms and / or linkages.

[0016] The coupling section on the pivot rod is preferably a connection point through which the pivoting motion of the pivot rod can be transmitted to a mechanical actuation device. For example, an opening, a fork, or a hook. Preferably, a freewheel is disposed between the pivot rod and the door lock. By means of a device referred to herein as a freewheel, the pivot rod can be actuated within a limited range of swing without transmitting the actuation to the door lock and / or the mechanical actuation device. For example, the coupling area has a slotted guide for a Bowden cable connector as a freewheel.

[0017] The pivot lever is preferably an operating element by which the user operates the mechanical actuation device. It preferably has a rest position and a mechanically actuated position, in which the door lock is mechanically actuated.

[0018] The pivot rod preferably has a retracted position and an extended position. Preferably, in the retracted position, the pivot rod is recessed into the adjacent surface in a flat or flush manner from end to end, or in a flat or flush manner except for the recessed handle, into the adjacent surface (e.g., the surface of the gripping area). Preferably, the pivot rod can be gripped by hand in the extended position, or can be gripped better than in the retracted position. The retracted and extended positions are preferably defined by a mechanism (e.g., a locking device) such that if they are in place, they are stable positions in which the pivot rod remains in place unless additional main force (e.g., manual pressing / pulling, electrically generated force) is applied to the pivot rod.

[0019] The pivot rod is preferably pivotable relative to the gripping area. Preferably, a portion of the gripping area is fixedly connected to the side door to rotate with the side door.

[0020] In an alternative embodiment, the pivot rod may pivot together with the gripping area, and / or the gripping area or the axial region of the gripping area itself forms the pivot rod, or the pivot rod itself forms the gripping area, wherein the pivot rod preferably forms the entire gripping area at least in the axial portion of the gripping area.

[0021] Preferably, a locking device is provided that, under normal conditions, fixes the gripping area, at least preventing it from pivoting, or restricts possible pivoting movement, or restricts possible pivoting movement more strongly than in the state with the locking device released, and pivoting of the gripping area and / or the pivot rod for mechanically actuating the door lock is only possible when the locking device is released. Preferably, the pivot rod is designed as a handle with two connection points, one of which can be released by the locking device.

[0022] Preferably, the pivot rod integrated into the gripping area and the gripping area form a unique inner door handle, which is configured to securely hold and / or pull a closed door, and has a gripping area that can be held in 360°, preferably any single inner door handle.

[0023] The interior door handle preferably consists of at least one outer grip plate and an inner grip plate. Here, a pivot rod is preferably mounted so that it can pivot between the two grip plates. The direction of the axial extension is preferably the longitudinal direction of the interior door handle, that is, during normal gripping of the gripping area, the direction of the axial extension is transverse to the fingers of the gripper. The extent of the axial extension of the gripping area is preferably measured by the shortest free distance on the door panel surface between the attachment points of the interior door handle. The interior door handle preferably has a lower end and an upper end. It is preferably an interior door handle arranged diagonally (forward; where "forward" refers to the positive X direction of the vehicle coordinate system). Preferably, the upper end is further forward than the lower end. The lower end is preferably recessed into the arm support area, preferably in a flat and flush manner. Preferably, the interior door handle is designed in the form of a handle with attachment points facing the side door in two different fastening areas, and with a gripping area located in the middle. The pivot rod preferably has a longitudinal extension in the rod direction. The longitudinal extension is preferably measured from the axis of rotation to the distal end of the pivot rod. Preferably, the longitudinal extension of the pivot rod is greater than the lateral extension of the interior door handle. Preferably, at least 50% of the pivot rod's longitudinal extension overlaps with the gripping area, and / or at least 50% (e.g., 50-60% or 80%) of the gripping area's longitudinal extension overlaps with the longitudinal extension of the pivot rod.

[0024] The axis of rotation is preferably substantially parallel to the lane plane or the vehicle floor and transverse to the straight-line direction of travel of the motor vehicle, that is, oriented parallel to the Y-direction.

[0025] The door lock actuator preferably has a spring that pre-stresses the pivot rod in a direction B (opposite to A) in the opposite direction A (the pivoting direction of the pivot rod for mechanically actuating the door lock). This spring is preferably separate from a spring that may be present in the door lock or another spring present in the door lock actuator.

[0026] Preferably, the expression "substantially" in conjunction with directional or angular relationships (e.g., "lateral" or "same direction") is generally understood to mean a tolerance range of ±30°, preferably ±15°, and particularly preferably ±5°. Particularly preferably, the word "substantially" may also be removed to refer to a precise directional or angular relationship.

[0027] In another exemplary embodiment of the invention, the pivot extends into at least one fastening region and defines a surface therein that is bent or flexed relative to the pivot at an angle ranging from 30° to 225°, and is preferably accessible by hand in the rest position of the pivot.

[0028] Therefore, the pivot can be operated manually more effectively. A surface is provided that can contact one or more fingers in a frictional or form-fitting manner to facilitate pulling the pivot in direction A. The surface that bends or curves around the gripping area is preferably a surface segment whose surface normal, together with the surface normal in the gripping area, forms the aforementioned angle. The bending axis of the bend or curve of the portion connecting the surface to the pivot in the gripping area is preferably parallel to the axis of rotation.

[0029] In another embodiment of the invention, the pivot rod is formed on the upper side in the fastening area. Thus, the pivot rod can be pressed or pulled by contact from above.

[0030] In another exemplary embodiment of the invention, the pivot rod has a front side at its upper end, which preferably forms an overhang, wherein the overhang preferably forms a finger groove for one to three fingers, preferably two fingers, which can be hooked into the front side by means of one or more fingers of the hand. Thus, the pivot rod can be pulled in a form-fitting manner using one or more fingers.

[0031] In another embodiment of the invention, the door lock actuator has an inertia compensation spring that pre-stresses the pivot rod for actuating the mechanical actuation device against the pivoting direction of the pivot rod, wherein the spring applies a load directly or indirectly to the pivot rod only when the pivot rod has moved from the retracted position to the extended position.

[0032] This allows for maintaining the smallest possible actuating force required to move the pivot from the retracted position to the extended position, while meeting requirements such as those needed in the event of a rear-end collision or undesirable mechanical lock actuation due to inertia. Preferably, the inertia compensation spring does not apply a load to the pivot between the held and extended positions. Preferably, the lock actuator includes a second spring, such as the spring described above, which pre-stresses the pivot in direction B (opposite to A) at least between the retracted and extended positions, against direction A (the pivoting direction of the pivot for mechanically actuating the lock). Preferably, the restoring force of this spring is less than the restoring force of the inertia compensation spring.

[0033] Preferably, and particularly, this exemplary embodiment can be considered a standalone invention, which can then be continued in a separate application, wherein the door lock actuator is not necessarily an interior door actuator, and an interior door handle (or door lever) is not necessarily present, with the pivot rod integrated into the door handle. However, in other respects, the features mentioned herein may also be applied as optional and preferred features.

[0034] In another exemplary embodiment of the invention, the door lock actuator has a push-push element configured to pivot the pivot rod to an extended position due to pressure on the pivot rod, whereby the pivot rod can be gripped by hand or in a better manner relative to the retracted position of the pivot rod. This allows for comfortable removal of the pivot rod, enabling a better grip and more comfortable actuation of the pivot rod. The push-push element is preferably a non-locking push-push element, and particularly preferably a locking push-push element, i.e., a locking device.

[0035] In another embodiment of the invention, the push-push element is disposed in the lower half of the interior door handle, preferably in the gripping area. Thus, an attractive design where the interior door handle tapers upwards is technically feasible because components requiring installation space are shifted downwards.

[0036] In another exemplary embodiment of the invention, the door lock actuator has a locking device that is preferably unlockable by means of a manual unlocking motion, by means of which a locking action, preferably a form-fitting action, is provided for the pivot rod relative to the actuation direction of the mechanical actuator.

[0037] Thus, the actuating device is fixed to prevent accidental actuation. Preferably, the pivot is held in its rest position by a locking device. This locking action is preferably form-fitting and / or non-form-fitting and / or magnetic or electromechanical. That is, the locking action does not necessarily require a form-fitting "latch," but can also be achieved by a maximum holding force, which must be overcome in order for the pivot to move in the actuation direction of the mechanical actuation device. After overcoming the maximum holding force, the force required to move the pivot further in the actuation direction of the mechanical actuation device is at least again less than the maximum holding force. The user, for example, understands this type of locking action as a biting action of the pivot entering the locked position, and the unlocking action as a disengaging action of leaving the locked position to the unlocked position. Preferably, the locked position of the pivot is a retracted position, preferably a retracted position that is substantially flat and flush with (and possibly the remaining recessed grips). In another exemplary embodiment of the invention, the locking device has two springs that apply opposing stresses, the rest position of which defines at least one extended position of the pivot.

[0038] This is a mechanically advantageous variant designed to limit the extension position of the pivot.

[0039] The preferred resting position is one in which the sum of the spring forces is less than the frictional and / or adhesive forces of the pivot rod mounting, or in which the pivot rod remains in place without any additional external or active force acting upon it, thus also being a resting position region.

[0040] Preferably, and particularly, this exemplary embodiment can be considered a standalone invention, which can subsequently be continued in a separate application, wherein the door lock actuator is not necessarily an interior door actuator, and an interior door handle (or door lever) is not necessarily present, with the pivot rod integrated into the door handle. However, in other respects, the features mentioned herein may also be applied as optional and preferred features.

[0041] In a variant based on this, the locking device includes, for example, a blocking element that prevents the pivot rod from being in a retracted position. When the blocking element is released (e.g., by manually pressing a pressure surface), the spring imbalance between the two springs resisting the pre-applied stress causes the pivot rod to move to an extended position, in which the spring balance predominates. Another variant is, for example, another exemplary embodiment described below.

[0042] In another exemplary embodiment of the invention, one of the springs is a spring stop, and preferably, the other spring is a linear spring, wherein the spring stop, together with the other of the two springs that apply stress to each other, defines a second rest position, which defines the retracted position of the pivot rod.

[0043] Therefore, the retracted position is defined as a stable and locked position, even if a locking device or blocking element is not necessarily present. A spring stop is preferably understood to represent a spring with a non-linear spring characteristic curve, preferably having at least one extreme or saddle point. For example, this relates to a disc stop or what is called a clicker spring in German usage. The spring stop preferably has two extension regions, separated from each other by an extreme or saddle point or discontinuity (typically: a snap point). The first region extends from the relaxed state of the spring stop to the snap point, and the second region extends further from there to the maximum extension of the spring stop. The spring stop preferably applies a load to the pivot rod in direction A, that is, the spring stop pushes the pivot rod from the retracted position to the extended position; while another spring thus applies a load to the pivot rod in direction B. In the extended position, the spring stop is preferably relaxed or located in the first region of the spring stop. When the pivot rod is between the extended and retracted positions, the snap point of the spring stop is present. In the retracted position, the spring stop is preferably located in the second region and forms a rest position with the other spring. Furthermore, the rest position can be fixed by a blocking element.

[0044] In another exemplary embodiment of the invention, the locking device has a locking element located in a locked position at a defined angular position or a defined angular range of the pivot rod, preferably one or both of the retracted and extended positions. For the locked position, the following are possible:

[0045] - By overcoming a predetermined pivoting torque along at least the actuation direction of the mechanical actuation device, the locked position is disengaged, and / or

[0046] - The locked position is disengaged by manually, directly or indirectly tensioning the spring element, that is, preferably (further) setting it in a tensioned state.

[0047] This provides a preferred embodiment of the locking device. The provision of a locking element (capable of disengaging from its locked position by overcoming a predetermined pivoting torque) is a preferred embodiment for preventing panic. The spring element is generally understood as a flexible, deformable, reset element. The locking element is preferably a locking flange. In its stopped position and the resting position of the pivot rod, it preferably rests against a blocking profile on a component fixed relative to the pivot rod 30.

[0048] In another exemplary embodiment of the invention, the locking device has the push-push element, and the push-push element has the locking element, wherein the push-push element, in a blocking state, is preferably able to block the pivot rod from at least one defined pivot angle against pivoting movement in the direction of the door lock actuator by means of the mechanical actuation device, and release the push-push element by movement of the pivot rod in a direction opposite to movement in the direction of the door lock actuator by means of the mechanical actuation device, thereby enabling the door lock to be actuated by means of the mechanical actuation device and / or enabling the pivot rod to be moved from a retracted position to an extended position.

[0049] This provides an advantageous combination of an outward pivoting mechanism and a locking device that facilitates gripping of the pivot rod. Movement of the pivot rod in direction B is preferably achieved by manually pressing the pivot rod against the spring element.

[0050] In another embodiment of the invention, the door lock actuator has a manually actuated electrical switch connected to the door lock via a signal line, thereby enabling the door lock to be electrically actuated by means of the switch.

[0051] This provides a second possibility for door lock actuation. Preferably, the door lock actuator is configured to actuate the door lock by switching on under normal circumstances and by mechanical actuation in an emergency.

[0052] The signal line is preferably a line used to transmit switching signals, whether it is a physical line or wireless. For example, the signal line is a cable or a radio link. The signal line may include different nodes or switching / preparation / processing points (digital or analog), such as a central control unit, and sections with various transmission media.

[0053] A switch is preferably understood to refer to an electromechanical device configured to generate an electrical switching signal, which is, for example, particularly preferably a microswitch. However, it is also conceivable to provide a sensor-supported switch mechanism with a sensor (e.g., a Hall sensor) and an evaluation unit (e.g., a microcontroller, a comparator). Actuation of the switch is preferably understood to bring the switch from one switching state to another. Preferably, the switch can be actuated, for example, in direction B, by means of the pivoting movement of a pivot rod. Preferably, the switch is covered by a flexible wall that can be manually pressed to actuate the switch. Preferably, the switch is integrated into the pivot rod, preferably in the distal third, preferably a quarter, and particularly preferably at the end of the pivot rod. For example, the switch can be actuated behind the flexible wall, preferably by deformation of the wall on the front or upper side of the pivot rod. However, instead of a flexible wall, it is also conceivable to use a (bare) button.

[0054] In another embodiment of the invention, the direction of motion for actuating the switch and the direction of motion for actuating the mechanical actuation device are substantially the same.

[0055] This is beneficial in preventing panic. If a user wants to mechanically open the door in an emergency, they can trace back to their habitual movement patterns during door lock actuation via a switch. When mechanical actuation is performed, the switch must preferably be actuated beforehand.

[0056] Preferably, and particularly, this exemplary embodiment can be considered a standalone invention, which can then be continued in a separate application, wherein the door lock actuator is not necessarily an interior door actuator, and an interior door handle (or door lever) is not necessarily present, with the pivot rod integrated into the interior door handle. However, in other respects, the features mentioned herein may also be applied as optional and preferred features.

[0057] In another exemplary embodiment of the invention, the locking device can be unlocked by means of a manual unlocking motion, and the direction of the motion used to actuate the switch is substantially the same as the direction of the unlocking motion.

[0058] When a locking device is present, this is advantageous in preventing panic. Preferably, the switch must be actuated before or simultaneously with unlocking during the unlocking motion.

[0059] Preferably, and particularly, this embodiment can be considered a standalone invention, which can then be continued in a separate application, wherein the door lock actuator is not necessarily an interior door actuator, and an interior door handle (or door lever) is not necessarily present, with the pivot rod integrated into the interior door handle. However, in other respects, the features mentioned herein may also be applied as optional and preferred features.

[0060] In another exemplary embodiment of the invention, the door lock actuator, in addition to the pivot rod, has a pressure mechanism, wherein the pressure mechanism is configured to deflect manual pressure acting on the pressure mechanism toward the pivot rod in the actuation direction of the mechanical actuation device.

[0061] Thus, the pivot rod can be moved in the actuation direction of the mechanical actuator by means of manual pressure, for example by means of pressure, so that the pivot rod is moved from a substantially flat and flush retracted position to an extended position.

[0062] Preferably, the pressure mechanism has a touch surface that can be directly applied manually, which is, for example, part of a rocker arm as mentioned below or connected to a rocker arm via a touch surface coupling segment. Preferably, the touch surface is positioned directly adjacent to the pivot rod and / or also integrated into the gripping area of ​​the interior door handle. The pressure mechanism is preferably a purely mechanical mechanism that couples the touch surface to the pivot rod. With the aid of the pressure mechanism, the pivot rod can be actively pressed out, thereby allowing it to be gripped. The pressure mechanism is preferably specifically mounted with respect to the door, and more preferably with respect to the interior door handle. The pivot rod is preferably independently movable relative to the pressure mechanism.

[0063] The pressure mechanism preferably has a rocker arm. The rocker arm is preferably mounted to be rotatable about a rocker arm axis. The rocker arm axis is preferably parallel to the pivot axis of the pivot rod. Preferably, the rocker arm has a pivot rod coupling section. This pivot rod coupling section is preferably arranged to rotate about the rocker arm axis at least 90°, preferably 180° with respect to the touch surface or touch surface coupling section. Preferably, the rocker arm axis is located between the touch surface, or the touch surface coupling section, and the pivot rod coupling section. The pivot rod coupling section is preferably supported in at least some specific pivot rod / rocker arm positions on the pivot rod and is configured to transmit rotation of the rocker arm about the rocker arm axis to the pivot rod, thereby causing the pivot rod to pivot along the actuation direction of the mechanical actuation device.

[0064] Preferably, if a manually actuated electric switch is present, a rocker arm or a touch surface coupled to the rocker arm (if present) is configured to actuate the switch directly or indirectly due to pressure on the touch surface (alone or as part of the rocker arm) and the resulting movement of the touch surface. Preferably, the rocker arm is not yet against the pivot rod in the pivoting region required for actuating the switch, so that no pressing force is deflected onto the pivot rod when the switch is actuated. Preferably, the rocker arm is configured to move the pivot rod in the actuation direction of the mechanical actuation device when the touch surface moves, the movement of the touch surface exceeding the movement for actuating the electric switch. This allows the switch to be actuated with a light / normal press, and with a strong press, the pivot rod is moved, for example, into the extended position.

[0065] Preferably, the rocker arm is prestressed to a rest position by means of a spring. Preferably, another end of the spring (which also prestresses the pivot arm in direction B to a rest position) applies a load to the rocker arm, so that only one spring is needed to hold the pivot arm and the rocker arm in their rest positions. The rest position of the rocker arm is preferably configured such that the touch surface (alone or as part of the rocker arm) is recessed flat and flush into the surface adjacent to it, preferably the gripping area and / or the surface of the pivot arm.

[0066] Preferably, the pressure mechanism is coupled to the locking element of the locking device (if the locking device has a locking element), wherein the pressure mechanism is configured to release the locking element when the pressure mechanism is pressed beyond a certain point, for example, when a switch is present and the pressure is pressed further than required to actuate the switch.

[0067] Preferably, and particularly, this embodiment can be considered a standalone invention, which can then be continued in a separate application, wherein the door lock actuator is not necessarily an interior door actuator, and an interior door handle (or door lever) is not necessarily present, with the pivot rod integrated into the interior door handle. However, in other respects, the features mentioned herein may also be applied as optional and preferred features.

[0068] In another exemplary embodiment of the invention, the pivot rod is preferably recessed into the surface of the adjacent gripping area in a flat and flush manner from end to end in the retracted position.

[0069] This provides an attractive ergonomic design because the interior door handle can be comfortably gripped when used for tightening the closed or holding function. Surface is preferably understood to refer to the visible surface.

[0070] In another exemplary embodiment of the invention, the pivot bar, preferably in the retracted position, is flush and recessed into the surface of the adjacent gripping area, except for the engagement grooves preferably for one, two, or three fingers.

[0071] This also provides an attractive ergonomic design, as the interior door handle can be comfortably gripped when used for tightening the closed or holding function. Furthermore, even without push-push elements or bending / flexing surfaces, the pivot can be manually and relatively comfortably moved from its stationary position, allowing for a better hand grip. Surface is preferably understood to refer to a visible surface. Brief description of the attached diagram

[0084] Figure 1 A perspective view shows details of a side door 100 of a motor vehicle according to the invention, having a module according to the invention including a door lock brake 1 and an inner door handle 130. The side door has:

[0085] - A door lock actuator 1 for a door lock, wherein the door lock actuator 1 is an inner door actuator and has a pivot rod 30, the pivot rod being pivotable about a rotation axis 21.1 of a hinge 21, wherein the pivot rod 30 has a coupling section 33 for a mechanical actuation device 140 for the door lock, the mechanical actuation device 140 (here a Bowden cable) being coupled to the coupling section 33 in the installed state;

[0086] - Preferably, the interior door handle 130 has two fastening areas 132.1 and 132.2 and a gripping area 131 that can be gripped by hand from behind, allowing for a complete 360° gripping. The gripping area 131 has an axial extension 131a. A pivot rod 30 is integrated into the gripping area 131 of the interior door handle 130, wherein the axis of rotation 21.1 is oriented transversely to the axial extension 131a. The pivot rod 30 preferably has a longitudinal extension 30a along the rod direction.

[0087] Figure 2 This is a perspective view of a prior art module with a door lock actuator 1 and an inner door handle 130, wherein the pivot rod 30 is not integrated into the gripping area 131 of the inner door handle 130, and furthermore, the rotation axis 21.1 is not oriented transversely to the axial extension 131a.

[0088] Figure 3 Based on Figure 1 A perspective view of one embodiment of the present invention, wherein a switch 10 is additionally provided. The electrical switch 10 is connected to the door lock via a signal line, thereby enabling the door lock to be electrically actuated using the switch 10. The door lock actuator 1 further includes a push-push element 41, the push-push element being, for example, Figure 10 The push-push element shown is located in the lower half of the inner door handle 130, specifically in the lower half of the gripping area 131. It is configured such that pressure on the pivot rod 30 pivots the pivot rod to a position that allows for hand gripping or is better suited for hand gripping (see...). Figure 4b In its resting position (see...) Figure 1 , Figure 3The pivot rod 30 is flush and recessed into the surface of the adjacent gripping area 131 from end to end. The interior door handle 130 is fixed to the door 100 at an angle extending forward and upward. Auxiliary lines are drawn to help distinguish the different areas 132.1, 131, and 132.2 of the interior door handle 130 from each other. The longitudinal extension 30a is preferably measured from the axis of rotation 21.1 to the distal end of the pivot rod 30. The axial extension 131a of the gripping area 131 is preferably measured by the shortest free distance on the door panel surface between the attachment points of the interior door handle 130. The pivot rod 30 overlaps the gripping area 131 with 100% of its longitudinal extension 30a. Approximately 80% of the longitudinal extension 131a of the gripping area 131 overlaps with the pivot rod 30. Switch 10 is preferably actuated by means of pivoting the pivot rod 30 in the direction B.

[0089] Preferably, the push-push element can be part of the locking device 40, such that the push-push element not only pivots the pivot rod 30 outward, but also, in the blocked state, can block the pivot rod 30 relative to the movement A actuated by the mechanical door lock. In this case, the door lock brake 1 shown here has a locking device 40 that can be unlocked by means of a manual unlocking movement, by means of which the locking device preferably provides a form-fitting lock of the pivot rod 30 relative to the movement along the actuation direction A of the mechanical actuation device. The locking device 40 has a locking element that is in a locked position at a certain angular position or within a certain angular range of the pivot rod 30, wherein it can be disengaged from the locked position by manually and indirectly applying stress to a spring element, such as part of the push-push element 41. The locking device 40 has a push-push element 41. The push-push element 41 has a locking element. In the blocked position, the push-push element 41 is blocked relative to the movement A of the door lock actuation by means of the mechanical actuation device 140 (see Figure 4c The pivoting motion of the pivot rod 30 is blocked by the pivoting motion of the pivot rod. (See also...) Figure 4a The pivot 30, as shown, releases the locking element by moving in direction B, which is opposite to the direction A of actuation of the lock by means of the mechanical actuation device 140. This movement is initiated by manually pressing the pivot 30, either indirectly or directly, against the spring element, thereby enabling the mechanical actuation device 140 to actuate the lock. The locking device 40 can be unlocked by a manual unlocking movement along direction B, and the direction of movement for actuating the switch 10 is the same as direction B. Furthermore, when performing the unlocking movement, the switch 10 must be actuated before or simultaneously with unlocking.

[0090] Figures 4a-4c Based on Figure 1 and Figure 3Three-dimensional views of different operating states of the present invention.

[0091] Figure 4a This illustrates how, by applying pressure along direction B on the pivot 30 (here, direct pressure, however, another operating element 20 could also be connected between the two), the switch 10 can preferably be actuated near the distal end of the pivot 30, away from axis 21.1. If the push-push element is integrated, it can be activated by further pressure from the switching point, thereby pressing the pivot 30 into a protruding position in which the pivot can be gripped essentially or at least better than before (i.e., particularly using the traction surface), such as... Figure 4b As shown. Alternatively, it can be done manually (e.g., by means of manual clamping fixtures on both side surfaces or by means of embedding into) Figure 5 The finger in the engagement groove 133 shown brings the pivot rod 30 into place. Figure 4b In the position shown, the push-push element 30 can be omitted depending on the required form of comfort and operation. Figure 4b In the position shown, the pivot rod 30 can be satisfactorily grasped by hand, and the pivot rod 30 can be pulled further in direction A until... Figure 4c As shown in the figure, the mechanical actuation device 140 actuates the door lock in the aforementioned position.

[0092] Figure 5 This is a perspective view of another embodiment of the invention based on the foregoing figures, which has an engagement groove 133. In its rest position shown here, the pivot 30 is flat and flush with the adjacent gripping area 131, except for the engagement groove 133 for two fingers.

[0093] Figures 6a-6d They respectively show the basis Figure 1 A perspective view of another embodiment of the present invention ( Figures 6a-6c ) and cross-sectional view ( Figure 6d Details of the pivot 30. The pivot 30 extends into the fastening region 132.2. There, as shown in conjunction with Figure 7c, its defining surfaces 34, 35, and 38 are bent or flexed relative to the pivot 30 in the gripping region 131 at angles 37, 37', and 37” ranging from 30° to 225°, where angle 37 is approximately 30°, angle 37' is approximately 135°, and angle 37” is approximately 190°. Here, there may also be... Figure 3 The push-push element is shown. The pivot rod 30 forms an upper side 34 in the fastening region 132.2. (As shown) Figure 6dAs shown, the pivot rod forms a front side 35 at the end of the upper side 34, which can be hooked by one or more fingers of the hand. Finger grooves 38 for one to three fingers, preferably two fingers, are preferably formed below the overhang. The inner door handle 130 is formed by at least one outer grip plate 134 and an inner grip plate 135, where the pivot rod 30 is mounted to allow it to pivot between the two grip plates 134, 135. The location of the mechanical actuation device of the pivot rod 30 actuating the door lock actuator is outlined in dashed lines and indicated by 30'. Considering the upwardly curved upper side 34 and especially the even further curved front side 35 and / or even further aided by the finger grooves 38, there is an actuating surface available for moving the pivot rod 30 in direction A, even without a push-push element. Therefore, it is preferable that the pivot rod 30 is flat and flush with the surface of the adjacent gripping area 131 from beginning to end.

[0094] Figures 7a-7c Cross-sectional views of one embodiment of the present invention, based on 6a-6d, are shown respectively. Figure 7a , 7c ) and perspective ( Figure 7b The details include an additional switch 10. The manually actuated electrical switch 10 is connected to the door lock via a signal line, allowing the door lock to be electrically actuated using switch 10. (See details...) Figure 7a As shown and from Figure 7c As can be seen in the cross-section, the switch can be actuated particularly well by applying pressure to the upper surface 34, wherein, in this embodiment, the pivot rod 30 need not pivot along direction B for this purpose, because the switch 10 can be pressed by means of the flexible upper wall of the pivot rod. Alternatively, it is also suggested that the switch 10 be configured such that the pivot rod 30 pivots completely in direction B in order to actuate the switch 10. Figure 7a As shown, mechanical door lock actuation is also provided by traction action at the front surface 35 and / or finger groove 38.

[0095] Figures 8a to 8b They are shown respectively as follows Figures 7a to 7b Details of the cross-sectional view of a variant of the embodiment of the invention shown. Switch 10 is actuated here by pressure applied to the front surface 35 and / or the finger groove 38. The direction of movement for actuating switch 10 is substantially the same as the direction of movement for actuating the mechanical actuation device 140, because the hand force applied to surface 35 not only switches switch 10 ( Figure 8a Furthermore, it causes the pivot rod 30 to pivot back. Figure 8b The switch can be actuated behind the flexible wall 36 on the front side 35 of the pivot rod 30 if the wall 36 deforms; however, alternatively, a (bare) button may also be conceivable.

[0096] Figures 9a-9b They respectively show the basis Figures 8a-8b A perspective view of one embodiment ( Figure 9a ) and cross-sectional view ( Figure 9b Details of the details are shown, with an additional example of a locking device 40. The door lock actuator 1 has a locking device 40 that can be unlocked by a manual unlocking movement. By means of this locking device 40, a form-fitting lock is provided for the pivot 30 relative to movement along the actuation direction A of the mechanical actuator. The locking device 40 has a locking element 42 that is in a locked position at a specific angular position or within a specific angular range of the pivot 30. This locked position can be disengaged by manually applying stress to the flexible wall 36, which acts as a spring element. In the locked position of the pivot 30 ( Figure 9a In the rest position, the locking element 42 (here, the locking flange) is supported on a blocking profile (not shown), such as at least one gripping plate 135, 135', on a component fixed relative to the pivot rod 30. Therefore, the locking flange prevents the pivot rod 30 from rotating in direction A. If the locking flange subsequently enters the release position by pressure on the flexible wall 36, the locking flange can rotate through the blocking profile when the pivot rod 30 pivots in direction A.

[0097] Therefore, the locking device 40 can be unlocked by a manual unlocking motion. Furthermore, the direction of movement for actuating the switch 10 and the direction of the unlocking motion are substantially the same. Additionally, when performing the unlocking motion, the switch 10 must be actuated before or simultaneously with unlocking.

[0098] Figure 10 It is shown here based on Figure 1 , Figures 3 to 5 A schematic diagram of the positioning of the push-push element, however, in Figures 6a to 9b In this embodiment, it is also preferably configured in this way. The coupling region 33 here has a freewheel in the form of a slot guide for a Bowden cable connector.

[0099] In all the embodiments shown, the longitudinal extension 30a of the pivot 30 is preferably larger than the lateral extension or cross-section of the inner door handle 130, and the axis of rotation 21.1 is preferably substantially parallel to the lane plane or vehicle floor and oriented transversely to the straight forward direction of travel of the vehicle. Furthermore, in all embodiments, it is preferable that a spring prestresses the pivot 30 against direction A along direction B, wherein this is preferably a spring separate from, for example, the possible spring of the door latch, in which the mechanical actuation device 140 operates against said spring.

[0100] Figures 11a-11c Based on Figure 1A schematic diagram of a door lock actuator with an additional pressure mechanism 50 in various states. The design of the inner door actuator, the inner door handle 130, and the integration of the pivot rod 30 into the gripping area 131 of the inner door handle 130 are not necessarily essential, and can be protected, for example, as separate applications.

[0101] Pivot 30 has a retracted position ( Figure 11a ) and the position of the extension ( Figure 11b In the retracted position, the pivot rod 30 is recessed into the adjacent surface in a flat and flush manner from end to end. In the extended position, the pivot rod 30 can be gripped by hand, allowing it to be pulled.

[0102] The door lock actuator 1 has an unlockable locking device 40, by means of which provides a locking action for the pivot rod 30 in the retracted position relative to movement along the actuation direction A of the mechanical actuator. The locking action is achieved by means of a maximum holding force that must be overcome to allow the pivot rod 30 to move from the retracted position along the actuation direction A of the mechanical actuator, wherein, after overcoming the maximum holding force, the force required to further move the pivot rod along the actuation direction of the mechanical actuator is again less than the maximum holding force. The retracted and extended positions are defined by means of the locking device such that if they are already in place, they are stable positions in which the pivot rod 30 remains in place unless additional main force (e.g., manual pressing / pulling, electrically generated force) is applied to the pivot rod. The locking device 40 has two opposing springs 43, 44, one of which, in a rest position, defines the extended position of the pivot rod 30. One spring 43 is a spring stop 43 and the other spring 44 is a linear spring. The spring stop 43, together with the other spring 44, defines a second rest position, which defines the retracted position of the pivot rod 30. Here, the linear spring 44 is a helical spring, inserted into the retaining pin, with one end pressing against the pin of the pivot rod 30. Figure 11a In the middle, spring stop 43 is pushed to its furthest position and is located on the other side of the latch point in the second area (relative to the relaxed state). Figure 11c ),exist Figure 11a In the middle, the spring stop 43 is located on this side of the latching point in the first area, and... Figure 11c The middle spring stop 43 is fully relaxed. The spring stop 43 presses the pivot rod 30 in direction A, that is, the spring stop 43 squeezes the pivot rod 30 from the retracted position to the extended position; another spring 44 applies a load to the pivot rod 30 in direction B.

[0103] The door lock actuator 1 has a manually actuated electric switch 10, which is connected to the door lock via a signal line, so that the door lock can be electrically actuated by the switch 10.

[0104] The door lock actuator 1, in addition to the pivot rod 30, also has a pressure mechanism 50, wherein the pressure mechanism 50 is configured to allow manual pressure applied to the pressure mechanism to ( ) Figure 11b The arrow in the diagram deflects along the actuation direction A of the mechanical actuation device onto the pivot rod 30.

[0105] The pressure mechanism 50 has a manually pressable touch surface 51, which is part of the rocker arm 52 mentioned below. The touch surface 51 is disposed directly adjacent to the pivot arm 30. The pressure mechanism 50 is a purely mechanical transmission mechanism that couples the touch surface 51 to the pivot arm 30. With the aid of the pressure mechanism 50, the pivot arm 30 can be actively pressed out, thereby allowing the pivot arm to be gripped. The pressure mechanism 50 is specifically mounted relative to the door, here mounted via the rocker arm axis 52.1 (see below).

[0106] The pressure mechanism 50 has a rocker arm 52. The rocker arm 52 is preferably rotatably mounted about a rocker arm axis 52.1. The rocker arm axis 52.1 is parallel to the pivot axis 21.1 of the pivot rod 30. The rocker arm 52 has a pivot rod coupling section 52.2. This pivot rod coupling section is arranged to rotate 180° about the touch surface 51 about the rocker arm axis 52.1. The rocker arm axis 52.1 is located between the touch surface 51 and the pivot rod coupling section 52.2. The pivot rod coupling section 52.2 is... Figure 11b and 11c The rocker arm 52 is supported on the pivot rod 30 and is configured to transmit the rotation of the rocker arm 52 about the rocker axis 52.1 to the pivot rod 30, thereby causing the pivot rod 30 to pivot in direction A.

[0107] The rocker arm 52 is configured to directly actuate the manually actuated electrical switch due to pressure on the touch surface 51 and the resulting movement of the touch surface 51. Preferably, within the pivot range of the rocker arm 52 required to actuate the switch 10, the rocker arm 52 is not supported on the pivot rod 30, so that no pressure deflection occurs onto the pivot rod 30 during switch actuation, and the pivot rod remains stationary. The rocker arm 52 is configured to move the pivot rod 30 in direction A during movement of the touch surface 51, the movement of the touch surface exceeding the movement required to actuate the electrical switch 10. This allows the switch to be actuated with a light / normal pressure, and with a strong press, the pivot rod 30 is moved, for example, into the extended position.

[0108] The rocker arm 52 is prestressed by a spring to enter the stationary position. Figure 11aIn this case, another end of spring 44 (which also pre-stresses the pivot 30 in direction B to enter the retracted position) applies a load to rocker arm 52, so that only one spring 44 is needed to hold the pivot 30 and rocker arm 52 in their rest positions. The rest position of rocker arm 52 is set such that the touch surface 51 is recessed into the adjacent surface in a flat and flush manner.

[0109] The locking device 40 can be unlocked by means of a manual unlocking movement (pressure applied on the pressure surface 51), and thus the direction of movement for actuating the switch 10 is the same as the direction of the unlocking movement. This is because, with further pressure applied beyond the actuation point of the switch 10, the pivot rod 30 can be brought from its retracted position, which is locked by means of the two springs 43, 44, into an extended position, which is no longer locked.

[0110] However, it is also conceivable that the pivot lever 30 is permanently prestressed in the extended position by (preferably only) a spring, and then brought to a rest position there by another spring (which could also be a spring from a mechanical door actuator). However, a blocking element initially locks the pivot lever 30 in the retracted position. By pivoting the rocker arm 52 past the actuation point of the switch 10, the blocking element is then released, and the pivot lever 30 pops out.

[0111] exist Figures 11a to 11c The possible operation of the example shown is as follows: To electrically actuate the door lock, the user can apply light pressure to the surface 51, actuating the switch 10 via the rocker arm 52. At this time, the pivot 30 does not move. When the user releases the pressure surface 51 again, the rocker arm 52 returns to its flush initial position due to the spring 44. By applying stronger pressure to the pressure surface 51, the pivot arm 30 can be moved from the retracted position to the extended position via the rocker arm 52, for example, in an emergency. Figure 11b During the transition from the retracted position to the extended position, the spring stop 43 returns from the engaged state to the disengaged state, wherein the spring stop in the disengaged state is at the latch point ( Figure 11b A greater force than before is applied to the pivot 30 near the point where the force applied to the pivot 30 in the opposite direction by the spring 44 is insufficient, causing the spring stop 43 to move again into the engaged state. Figure 11a Therefore, when the user releases the pressure surface 51, although the rocker arm 52 moves back to its rest position due to the spring 44 ( Figure 11a However, the pivot rod 30 remains in the extended position because of the spring balance between the spring 44 and the unengaged spring stop 43 in this position. The user can grasp the pivot rod 30 from here and mechanically actuate the door lock by pulling. Figure 11c ).

[0112] The present invention provides a door handle for an internally actuated vehicle side door including a door lock, which firstly provides a large lever for mechanical door lock actuation, secondly provides satisfactory integration and thus provides space savings with a small number of components.
