Definitions

  • the invention relates to an actuating device for a motor vehicle door lock, with a handle, and with a locking lever, which sets the handle at occurring acceleration forces of predetermined size, for example in an accident, ineffective.
  • the actuating device is usually mechanically coupled via a connecting means, for example a Bowden cable, an actuating rod, etc. with the motor vehicle door lock.
  • a connecting means for example a Bowden cable, an actuating rod, etc.
  • This can be acted upon by the handle in the simplest case, a release lever inside the motor vehicle door lock.
  • This release lever regularly lifts a pawl from a catch, so that the catch opens spring-assisted and releases a previously captured locking pin.
  • the motor vehicle door lock is opened and it can also be opened or otherwise opened an associated motor vehicle door.
  • the locking lever is provided.
  • the locking lever sets the handle ineffective associated with an accident occurring acceleration forces of predetermined size. This means that the acceleration forces in question do not cause the motor vehicle door lock to be opened unintentionally as a result of the action of the locking lever.
  • persons located in the interior of a motor vehicle body obtain maximum protection and can, in particular, deploy maximum safety here, such as side impact protection, airbag, etc.
  • the control works in turn on a securing part, which engages in a crash in a groove-shaped recess and thereby blocks the handle.
  • a locking lever is realized, which cooperates with a stationary counter-locking surface. In a crash and the associated mass forces forces the locking lever pivoted into a lock the door handle locking position.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of further developing such an actuating device for a motor vehicle door lock of the structure described at the beginning in such a way that a permanent and in particular still guaranteed functional reliability is observed.
  • a generic actuator is within the scope of the invention is characterized in that undergoes a deflection during normal operation of the locking lever when the handle and only in the blocking mode, the handle is ineffective.
  • the normal operation thus corresponds to the fact that the locking lever undergoes a deflection when the handle is acted upon.
  • Normal operation means that, for example, do not attack any acceleration forces associated with an accident.
  • each actuation of the handle corresponds to the fact that at the same time the locking lever is deflected.
  • the locking lever is also deflected at the same time. This ensures that any bearing for the usually rotatably mounted locking lever can not "caking" with time by, for example, corrosion, or even “rust down” in the worst case. Rather, the constant and regular loading of the locking lever ensures that this function even at high durability of
  • the locking lever in lock-up mode which is typically in Acceleration forces associated with an accident, now ensures that the handle is ineffective in its function. That is, any attacking on the handle also acceleration forces do not cause the release lever is actuated in the connected motor vehicle door lock. An associated motor vehicle door is logically not opened unintentionally.
  • the ineffectiveness of the handle in the blocking operation can be set up so that the handle with respect to the release lever in question performs or perform an idle stroke quasi, which is initiated by the locking lever in the blocking mode.
  • the procedure is such that the blocking lever blocks the handle during blocking operation.
  • the locking lever is advantageously equipped with at least one inertial mass.
  • the locking lever is usually a two-arm lever and in particular even a three-arm lever.
  • the locking lever has at least one with the handle optionally interacting stop arm and the inertial mass having inertial arm.
  • the inertial mass is connected to the end of the inertial arm. Since the locking lever is mounted in total rotatable about an axis of rotation, for example, in the interior of a motor vehicle door, significant torques can be built up and observed in the event of a crash with the aid of the inertial mass connected to the end of the inertial arm.
  • the handle and the locking lever are usually permanently elastically coupled together.
  • the coupling arm can be connected by means of a spring with the handle.
  • the spring is usually designed so that it has a spring constant which is adapted to the inertial forces built up by the handle.
  • the locking lever is additionally equipped with a rear-part device, which transfers it back to its original position after its rotatable deflection by actuation of the handle.
  • the return device may be a return spring.
  • the rear part device can also be controlled mechanically.
  • the interpretation is usually made so that the rear part device engages the inertial arm.
  • the locking lever is typically associated with a stop.
  • the stop is designed as an inertia stop. As a result, the stop or inertial stop can be limited by acceleration-induced deflections of the blocking lever. In normal operation, the handle ensures that the locking lever is deflected against the restoring force built up by the return spring.
  • this process corresponds to the fact that the locking lever performs a pivoting movement about its axis of rotation caused by the handle.
  • the handle may take the locking lever on the spring and the coupling arm.
  • the spring constant of this spring is designed so that the handle experiences only a slight deflection, at least the projection on the handle does not run against the stop arm of the locking lever. In principle, however, this can also be allowed to ensure additional fixation of the handle by means of the locking lever. In any case, the handle is blocked in the blocking mode by means of the locking lever. As a result, the trigger lever connected to the handle in the motor vehicle door lock can not be acted upon inadvertently so that the motor vehicle door lock retains its "closed" position unchanged.
  • the main benefits In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:
  • Fig. 1 and 2 the actuating device according to the invention schematically in different functional positions.
  • an actuating device for a motor vehicle door lock 1 is shown.
  • the motor vehicle door lock 1 has in its basic structure via a locking mechanism 2, 3 of the catch 2 and pawl 3. On the blocking
  • the trigger lever 4 operates a trigger lever 4.
  • the trigger lever 4 is connected via a flexible connecting means or a Bowden cable 5 to a lever 6, which is acted upon by a handle 7.
  • the handle 7 passes through a door 8 in an outer door panel of a motor vehicle door, not shown. Consequently, it is in the handle 7 to an outside door handle, although of course, an internal door handle can be constructed comparable.
  • An operator can act on the handle 7 pulling in the direction of the arrow shown in the figures. After the pulling action, the handle 7 returns to its original position. This is ensured by a return spring, not shown. In this normal operation shown in FIG. 1, the original position is shown in solid, whereas the deflected position of the handle 7 is indicated by dash-dotted lines. 2 now shows the deflected position of the handle 7 in normal operation.
  • a locking lever 10 additionally belongs to the basic construction of the actuating device.
  • the locking lever 10 deactivates the handle 7 when acceleration forces a of a predetermined magnitude occur, for example in the event of an accident.
  • the accelerating forces in question in the figures are indicated by an arrow a and correspond in the present case to a side impact, which of course is not to be understood as limiting.
  • Fig. 1 shows the original position solid.
  • FIG. 2 shows the deflected position of the handle 7 in normal operation.
  • the dot-dashed representation corresponds in FIG. 1.
  • the locking lever 10 is designed in the embodiment as a three-armed lever.
  • the locking lever 10 has a stop arm 10a, which interacts with the handle 7 or can interact.
  • the stop arm 10a is L-shaped and can interact with a projection 1 1 on the handle 7 as described.
  • the locking lever 10 also has an inertia arm 10b, which is equipped with an inertial mass 12.
  • the inertial mass 12 can be found at the end of the inertia arm 10b in order to be able to build up a maximum torque in the blocking operation with respect to a rotation axis 13 for the locking lever 10 which is pivotable relative thereto.
  • the locking lever 10 also has a coupling arm 10c, with the aid of the locking lever 10 is connected to the handle 7, and permanently elastic.
  • the coupling arm 10c and the handle 7 by means of a spring 14 are interconnected.
  • the further return spring 9 engages the locking lever 10, more precisely on the inertial arm 10b.
  • any other restoring device 9 can be realized, which ensures a return of the locking lever 10 to the original position shown in FIG.
  • a stop 15 for the locking lever 10 which defines the rest position of the locking lever 10.
  • the stop 15 is designed stationary and may for example be defined in the interior of the unspecified motor vehicle door.
  • the stop 15 is an inertia stop 15, which is accelerated by
  • the operation is as follows. Starting from the initial position of the actuating device, shown in solid line in FIG. 1, an action on the handle 7 during normal operation causes the handle 7 to be deflected or exposed relative to the guide 8 assigned to it. This is shown in phantom in FIG. 1 and shown in solid lines in FIG. 2. Due to the deflection of the handle 7 of the locking lever 10 is taken. In any case, the actuation of the handle 7 in normal operation causes the locking lever 10 is pivoted in the transition from Fig. 1 to Fig. 2 about its axis of rotation 13 in the counterclockwise direction. In this process, the inertial mass 12 moves away from its associated inertia stop 15 and the locking lever 10 releases the handle 7 after a certain angle of rotation.
  • each act on the handle 7 corresponds to the fact that the locking lever 10 undergoes the described deflection respectively a pivoting movement about its axis of rotation 13.
  • the handle 7 primarily ensures that the transmission lever 6 about its axis 16 also in the counterclockwise
  • the locking lever 10 ensures that the handle 7 is blocked in this blocking operation. Because the acceleration forces in question a primarily act on the inertial mass 12 and ensure that the locking lever 10 and the inertial mass 12 are pressed against the associated inertia stopper 15. In this way, the locking lever 10 is able to hold the handle 7 also. Because even at the handle 7 attack corresponding acceleration forces. In fact, the design is such that the handle 7 undergoes only a slight deflection relative to the locking lever 10, which is limited by the spring 14 with the locking lever 10 coupling spring 14. In the case of increased forces, the stop arm 10a in addition to the projection 11 on the handle 7 can additionally provide for the described blockage of the handle 7 in the locked mode.
