Definitions

  • the invention relates to an actuator for a lock of a door or flap of a motor vehicle according to the preamble of claim 1.
  • a lock has a locking mechanism comprising a catch and a pawl for locking the catch in a latching position, and optionally a blocking lever for blocking the pawl in its rest position.
  • the actuator is used to open the door or flap and allows unlatching of the locking mechanism.
  • the pawl is moved out of its locking position and optionally the blocking lever out of its blocking position and the locking mechanism is finally opened. Following this, the door or flap can be opened.
  • the actuating device usually has a release lever which is actuated in order to open or unlatch the locking mechanism.
  • a trigger lever is typically directly or immediately connected to a handle of the door or flap. It may be an external handle or an internal handle of the corresponding door or flap. If such a handle is actuated, the release lever is actuated or pivoted to unlatch the locking mechanism and thus to open the lock.
  • a crash case In an accident or a vehicle collision, also referred to below as a crash case, very abruptly very high acceleration forces occur, which can amount to a multiple of the gravitational acceleration. As a result, the corresponding lock, including the lever mechanisms, such as the actuating lever, exposed to considerable forces, which can lead to an unwanted opening of the locking mechanism and consequently an opening of the associated lock. In a crash case may also be the operating lever, so a door inside handle or outside door handle be operated unplanned, which would also lead to an opening of the locking mechanism.
  • an inadvertently opened motor vehicle door can no longer provide the safety devices present in it such as a side airbag or a side impact protection for the protection of the vehicle occupants.
  • mechanisms with so-called inertia are provided to prevent the opening of a door or flap in the event of excessive acceleration forces, such as occur in the event of a crash.
  • Such a mechanism has a movable inertial mass that must be moved to open the door or flap. If this movable inertial mass is not moved or not moved fast enough in the case of actuation of an outside door handle, the mechanism prevents the locking mechanism from opening.
  • a mechanism that can do this is, for example, from the publications EP 1 518 983 A2 or WO 2012/013182 A2 known.
  • An actuating device comprises the features of the first claim to achieve the object.
  • Advantageous embodiments emerge from the subclaims.
  • an actuating device for a door or flap of a motor vehicle with an external operating lever, an actuating lever for opening a locking mechanism and a clutch lever, wherein the coupling lever is capable of coupling the external actuating lever and actuating lever, and with a control lever, controls the coupling of the clutch lever in response to the acceleration of the external actuating lever, wherein a pivoting of the external actuating lever via a spring is capable of causing a pivoting of the control lever, wherein the spring is fixed to the external operating lever.
  • a lever arm of the clutch lever is advantageous to a contour of the control lever, so as to control in a technically simple manner and low noise.
  • the concern is in a technically simple design, in particular by a preloaded spring causes, which clamps the clutch lever in the direction of the control lever.
  • a pivoting of the control lever as a result of the pivoting of the external actuating lever is effected according to the invention by a spring.
  • the spring may behave like a rigid body in the case of normal accelerations, so as to transmit a pivoting movement of the outside operating lever to the control lever. At excessive accelerations, the spring does not behave like a rigid body due to an inertia member acting directly or indirectly on the spring. A Pivoting movement of the external operating lever will not transferred to the control lever without delay. This different movement behavior is used to control the coupling by the clutch lever in a suitable manner.
  • the spring is preferably a leaf spring, since this is technically very easy to manufacture and a spring constant is very precisely vergebbar.
  • the spring is according to the invention attached to the external actuating lever and in particular adjacent to a mounting option for a Bowden cable, a rope or a rod.
  • a spring can be mounted as suitable and with little space.
  • the spring is preferably attached to the external operating lever. With little effort so the spring can be installed properly with the desired force.
  • the clutch lever is preferably rotatably mounted on a lever arm of the trigger or actuating lever, which simplifies the coupling and requires a small space.
  • the external actuating lever preferably has a driver, in which the clutch lever is able to engage in order to be able to effect the coupling in a reliable and suitable manner.
  • the outer operating lever preferably has a slot into which a bolt of the control lever extends. Relative movements between the external operating lever and the control lever can thus be limited suitably for a reliable functioning of the actuating device.
  • the control lever preferably has a step-shaped contour so as to be able to control the one hand and on the other hand to avoid an excessive amount of material.
  • the control lever is preferably connected to a component of inertial mass which can be moved in response to accelerations of the external operating lever to prevent the clutch lever coupling the external operating lever with the operating lever at excessively high accelerations.
  • the actuating device serves as part of a locking device of a motor vehicle, in particular a side door lock, with a locking mechanism comprising a rotary latch and a pawl for locking the rotary latch. With the actuator, the locking mechanism can be unlocked.
  • the invention particularly relates to a release chain, for example in a side door lock of a motor vehicle with an active mass lock.
  • a coupling member between an external operating lever and an actuating lever is arranged.
  • the trailing control lever can also be labeled as a release lever.
  • the coupling member is rotatably mounted on the release lever and is spring-biased against a control lever of the moment of inertia. This makes it possible that with a movement of the control lever, the clutch lever can engage with the external operating lever.
  • the inertial mass is preferably formed as an annular element directly on the axis of rotation of the external actuating lever.
  • the annular element acts preferably at the same time as a control lever.
  • the clutch lever is also applied to a control contour of the annular inertia element.
  • the control contour can be formed by an annular recess.
  • the release chain of the actuator can be used in one embodiment simultaneously as a central locking element. It is formed, for example, an extension on the coupling member, which in turn works together with a bolt, for example, which prevents engagement of the coupling member in the driver of the external actuating lever or allows a freewheeling of the coupling member, so that a collapse of the coupling member is definable. Should be locked centrally, the coupling member is prevented by an electric drive from being able to come into the coupling position. So it is advantageous to have an electric drive, which is able to control the coupling, so as to lock and use the clutch lever in addition.
  • the FIG. 1 shows a mechanism of an actuating device for unlocking or opening a Gesperres, not shown, in an initial position in which the actuating device is not actuated.
  • the mechanism comprises an external operating lever 1 which is rotatably mounted by a shaft 2 on a plate or lock plate, not shown, or a housing of the actuator.
  • the plate or the housing can also be part of a connected, not shown lock, which includes a locking mechanism.
  • the external control lever 1 is connected via a Bowden cable 3, a rope or a linkage with an outside door handle, not shown.
  • the free end of the external actuating lever 1 has a fastening possibility 4 for the cable, linkage or the Bowden cable 3.
  • the external actuating lever 1 is pivoted about the axis 2 in a clockwise direction by means of the cable, the linkage or the Bowden cable 3.
  • a leaf spring 5 Adjacent to the mounting option 4, one end of a leaf spring 5 is attached to the outer operating lever 1.
  • the leaf spring 5 extends in the direction of the axis 2 of the external actuating lever and ends next to a bolt 6.
  • the spring 5 abuts against the bolt 6.
  • the bolt 6 is fixed to a rotatable control lever 7, which is also rotatably supported by said axis 2.
  • the control lever 7 is part of the inertial mass, since this must be moved to open a door or flap and this is not properly moved in the case of excessively high accelerations.
  • the control lever 7 is located in this embodiment above the external actuating lever 1.
  • the bolt 6 extends both upwards and downwards and upwards such that the bolt 6 is located next to the free end of the leaf spring 5.
  • the bolt 6 extends into a slot 8 of the external actuating lever 1.
  • the bolt 6 In the direction of rotation of the external actuating lever 1, ie in the clockwise direction, the bolt 6 is behind the leaf spring 5 This end of the slot 8 thus limits a rotational movement of the control lever 7 in the clockwise direction and relative to the external actuating lever 1.
  • the slot can the rotational movement of the control lever 7 also opposite to the clockwise direction relative to limit the external operating lever 1.
  • the leaf spring 5 behaves like a rigid body.
  • the free end of the leaf spring 5 then introduces a force into the bolt 6 and rotates it and thus also the control lever 7 in the clockwise direction about the axis 2.
  • the leaf spring 5 does not behave like a rigid one Body. This is because the spring force of the leaf spring 5 is not sufficient to accelerate the control lever 7 and an associated further component 9 of the inertial mass fast enough.
  • a triggering or actuating lever 10 is rotatably supported by the axis 2.
  • the actuating lever 10 includes a lever arm 11, with a non-illustrated pawl or a blocking lever, not shown, of the locking mechanism can be moved by pivoting the lever arm 11 in the clockwise direction from its locking position or from its blocking position, so as to open the locking mechanism, so to Disengage.
  • This pivoting of the lever arm 11 in a clockwise direction is only possible if the control lever 7 is pivoted in a clockwise direction by actuating the actuating device, as will be explained below.
  • the actuating lever 10 includes a further lever arm 12. Below the free end of the lever arm 12, a clutch lever 13 is rotatably mounted by an axle 14 at this free end.
  • a spring not shown, the clutch lever 13 is so opposite to further lever arm 12 of the actuating lever 10 biased that this spring is able to move the clutch lever 13 counterclockwise and that about the axis 14 around.
  • Such a counterclockwise rotation is in the in the FIG. 1 illustrated initial position, however, prevented because the free end 15 of a lever arm of the clutch lever 13 abuts a lateral contour 17 of the control lever 7.
  • the free end 15 may include a vertically projecting pin which is able to abut the contour 17.
  • the Indian FIG. 1 shown stepped profile of the lateral contour starting from the region 17 in the direction of the end with the bolt 22 favors the desired sequence of motions described below and reduces the use of mass and thus weight.
  • a pivoting of the control lever 7 in the clockwise direction allows a rotational movement of the clutch lever 13 about the axis 14 and that opposite to the clockwise direction. If the clutch lever 13 is pivoted counterclockwise by the spring, not shown, so passes a free end 16 of a further lever arm of the clutch lever 13 in a stepped recess 17 of a driver 18 into it, as shown in FIG. 2 is apparent.
  • the driver 18 with the stepped recess 17 is mounted on the external actuating lever 1. If the Hebelarmende 16 of the clutch lever 13 has been moved into this step-shaped recess 17 in, so has a pivoting of the outer actuating lever 1 in the clockwise with the result that also the actuating lever 10 is then pivoted in the clockwise direction.
  • the free end 16 is in the step 17 of the driver 18, the rotational movement is transmitted via the clutch lever 13 to the actuating lever 10 and thus pivots the free end 11 of a lever arm of the actuating lever for opening the locking mechanism in the clockwise direction, as shown in the FIG. 2 will be shown.
  • the leaf spring 5 does not behave like a rigid body due to the inertia of the control lever 7 and the component 9 of the inertial mass.
  • the control lever 7 can not or can not be swiveled fast enough about its axis 2 in the clockwise direction. This has the consequence that also the clutch lever 13 is not pivoted counterclockwise about its axis 14 and thus does not enter the stepped recess 17 of the driver 18 into it. Instead, the free end 16 of a lever arm of the clutch lever 13 is moved past the stage 17 and passes next to the lateral contour 19 of the driver 18, as shown in the FIG. 3 will be shown. Is this like in the FIG.
  • the free end 16 can no longer get into the step-shaped recess 17 into it. Further pivoting of the outer actuating lever 1 in a clockwise direction can therefore not cause the actuating lever 10 is pivoted for opening the locking mechanism also in a clockwise direction. In the case of an excessively high acceleration, the locking will therefore not open.
  • the component 9 of the inertial mass is fixed by an axle 20 to a plate or a housing. It may be the same plate or the same housing to which the axle 2 is attached.
  • the control lever 7 comprises a free Hebelarmende 21. At this free end 21, a bolt 22 is mounted, which extends into an arcuate slot 23 of the component 9 of the inertial mass inside. In the initial position, the cylindrical pin 22 is close to the axis 20.
  • the control lever 7 is pivoted in the clockwise direction. This pivoting of the control lever 7 in the clockwise direction exerts a force on the outer arcuate edge of the slot 23 of the component 9 of the inertial mass. It is so initiated a force in the component 9 of the inertial mass. The component 9 of inertial mass then rotates counterclockwise. This has the consequence that the pin 22 of the control lever 7 changes its position within the slot 23 of the component 9 of the inertial mass and is moved from one end of the slot 23 in the direction of the other end of the slot 23. This changes the leverage.
  • the lever ratios change such that the rotational speed of the component 9 slows down relative to the rotational speed of the control lever 7 and to the rotational speed of the external actuating lever 1 and of the actuating lever 10.
  • the leverage changes such that only initially a relatively large force in the component 9 of the inertial mass must be initiated in order to open an associated door or flap can.
  • the component 9 of the inertial mass is constructed rotationally symmetrical apart from the slot 23 in order to advantageously perform vibration-free rotational movements as possible. This contributes among other things to a low-noise opening. In the direction of the axis 20, about which the component 9 of the inertial mass can be rotated, there are a constriction similar to the number "8". This ensures that the material or the mass of the component 9 of the inertial mass increases with increasing distance from the axis 20. This contributes to be able to keep the mass and weight of the component 9 of the inertial mass low, and to provide the highest possible moment of inertia at the starting point of the movement for a control lever 7.
  • the slot 23 of the component 9 of the inertial mass can also serve to suitably limit pivoting of the component 9.
  • the slot 23 is shown very large in the present and merely exemplified form.
  • For a function of the actuator only a slight angular movement of the bolt 22 in the slot 23 is required, so that the bolt 6 comes to rest after a slight movement at an upper end of the slot 23.
  • stops 24 and 25 may be provided, the pivotal movements of the component 9 suitable limit.
  • the actuator may include other stops that ensure the proper position and location of components.
  • the outer actuating lever 1 may have a stop 26 which limits a pivoting movement of the clutch lever 13 in the clockwise direction.
  • the position of the actuating lever 11 can be fixed in the starting position.
  • the component 9 of the inertial mass in the form of a flattened "8" is reproduced, in the resting state, as in FIG. 1 shown, abuts a damping element.
  • the inert mass of the component 9 in this case interacts with the control lever 7, which in turn can be activated via the external actuating lever 1.
  • the principle is also transferable to other mass locks.
  • control lever 7 engages in a contour of the component 9 of the inertial mass, wherein the engagement point is initially arranged close to the pivot point, or the axis of rotation 20 of the component 9. This results in favorable leverage ratios and a high moment of inertia, which precludes the release chain external actuating lever 1, clutch lever 13, actuating lever 10.
  • the engagement conditions between the component 9 of the inertial mass and control lever 7 change, so that only very small forces for moving the inertial mass of the component 9 are required.
  • An exemplary position of the inertial mass of the component 9 is in a pivoted about 90 ° position in the FIGS. 1 and 2 shown. Unlike the in FIG. 3 exemplified position of the component 9, the component 9 in the in the FIG. 2 get shown situation. In this position, the component 9 can be held in the deflected position via a fixing device, not shown. If the component 9 is deflected and fixed, the control lever 7 can not return to its in the FIG. 1 reach the starting position shown. As a result, the clutch lever 13 remains in its coupled position, whereby an opening of the locking mechanism is prevented by bouncing. The clutch lever 13 remains disengaged because the external operating lever 1 can not be moved back to its original position. The outer actuating lever 1 is prevented by the abutment of the bolt 6 at the end of the slot 8 from moving back.
  • levers can be moved back into starting positions as needed, such as the control lever 7 and / or the operating lever 10th
  • the component 9 of the inertial mass may also be omitted if the control lever 7 has a sufficiently large inertial mass.
  • the control lever can also be shaped differently, such as those in the FIG. 4 shown ring shape 29, to which a bolt 30 is attached or formed.
  • the bolt 30 abuts against the leaf spring.
  • the annular mass inertia element 29 is rotatably mounted on the axis 2.
  • the bolt 30 in turn rests on the one hand on the spring 5 and on the other hand reaches into a slot 8 of the external actuating lever 1, so as to suitably limit relative movements.
  • the ring shape can be like in the FIG. 4 shown, having a recess to allow a concern of the Hebelarmendes 15 of the clutch lever 13 as shown.
  • a recess may be provided a slot or a bore into which a bolt of the Hebelarmendes 15 of the clutch lever 13 extends.
  • the ring mold 29 displaces the mass to the outside, which is associated with the advantage that a relatively large torque must be expended for moving the ring shape, without having to accept a relatively large weight in purchasing.
  • the ring shape also allows in comparison to the shape 17 of the control lever, a saving of space. Another component 9 of the inertial mass can then be eliminated regularly.
