Definitions

  • the invention relates to a locking device for a motor vehicle door lock to prevent unwanted opening of the door due to the action of excessive accelerations which act counter to the opening direction of the door, e.g. in the event of an accident acting on the vehicle in accordance with the features of the preamble of claim 1.
  • Such a blocking device is known for example from DE-AS 20 23 859.
  • a two-armed lever is provided as the blocking device, the first arm of which receives an additional mass and the second arm of which rests on a handle shaft connected to the handle of the door lock.
  • the additional mass causes an inertia force which is translated in accordance with the lever arms and which is opposed to the inertia force acting on the handle and therefore prevents the door from being opened unintentionally.
  • the invention has for its object to provide a blocking device of the type mentioned, which is simple and space-saving and yet safely prevents unwanted opening of the vehicle door at excessive accelerations.
  • the invention is essentially based on the idea that the lever of the blocking device is designed such that when the additional mass is moved in the opening direction of the door, the second lever arm laterally engages in a groove in the handle shaft and prevents its outward movement.
  • the additional mass of the first lever arm and the length of the lever arms in this case must therefore only be dimensioned such that the second lever arm engages in the corresponding groove of the handle shaft before the handle has moved appreciably outwards.
  • the restraining force acting on the handle shaft is essentially no longer the size of the additional mass, but rather the design of the second lever arm.
  • the blocking device can be designed particularly simply if the second lever arm has a hook-shaped attachment at its end, which engages in the corresponding recess in the handle shaft.
  • a locking part e.g. a leaf spring to be provided, which engages in a corresponding groove-shaped recess of the handle housing and holds the lever in this position.
  • the locking part In order to be able to subsequently open the motor vehicle door again by pulling the handle, the locking part must be able to be pressed out of the groove-shaped recess of the handle housing, for example by means of a corresponding device (for example a key), or else the second lever arm is provided with a predetermined breaking point and breaks at a specific pulling force from.
  • a particularly space-saving and safe arrangement of the blocking device is obtained if the additional mass is on the side facing away from the handle shaft and the pivot axis of the lever is on the side of the lock cylinder facing the handle shaft.
  • Fig. 1, 1 denotes the detail of an outer door handle for a motor vehicle, which essentially consists of a handle guide 2 and the actual handle 3.
  • the handle guide 2 is embedded in the door outer panel 4 shown in dashed lines.
  • the handle 3 has a handle shaft 5 protruding into the inside of the door, which is provided with a hook-shaped handle head 6 which, for the connection between the outer door handle 1 and a door lock (not shown for reasons of clarity) comprises an external operating lever (also not shown) (cf. DE 43 21 900 A1).
  • the handle shaft 5 contains a lateral recess 7, the purpose of which is explained in more detail below.
  • the blocking device 9 consists essentially of a pivotable about an axis 10 two-armed lever 11, the first lever arm 12 being L-shaped with respect to the axis 10 and provided with an additional mass 13.
  • the second lever arm 14 is straight with respect to the axis 10 and has at its end remote from the pivot axis 10 a hook-shaped projection 15 which is in the normal position (unblocked state) opposite the recess 7 of the handle shaft 5 and in this position a first leaf spring 16 fastened to the first lever arm 12 and supported on the handle guide 2 is held.
  • a second leaf spring 17 is also arranged on the first lever arm 12 and can be latched into a groove-shaped recess 18 in the handle guide 2 when the second lever arm 12 is moved accordingly.
  • FIG. 2 shows the side view of the outer door handle shown in FIG. 1 from the side of the handle guide 2 containing the locking cylinder 8. It can be seen that the area of the first lever arm 12, which lies between the pivot axis 10 and the additional mass 13, the locking cylinder 8 includes forked.
  • the hook-shaped extension 15 is provided with a predetermined breaking point 23 indicated by dashed lines (in a practical exemplary embodiment, the predetermined breaking point 23 was designed in such a way that the hook breaks off at a force of 250 N and thus the Door releases).
  • the invention is not limited to the exemplary embodiment described above. So it is possible, for example, to dispense with the second leaf spring 17 and to connect the second arm 14 of the lever 11 with the handle shaft in a positive and non-positive manner until there are practically no inertia forces due to the corresponding design of the hook-shaped extension 15 and the recess 7.
  • the groove 7 can be provided with a corresponding undercut in the direction of the handle head and the hook-shaped extension with a correspondingly long tip.
  • the blocking device can be changed such that the locking by means of the second leaf spring 17 is released in that when the locking cylinder 8 is rotated correspondingly, a bolt presses the leaf spring 17 out of the recess 18 on the locking cylinder side. For this it is only necessary to insert an additional slot-shaped recess between the existing recess 18 and the locking cylinder 8 in the handle guide 2.
