Definitions

  • the invention relates to an outside door handle for a locking device of a motor vehicle according to the preamble of claim 1, and a method according to the preamble of claim 17.
  • a door handle or such a method is known from WO-A-0100953 known.
  • an automatic locking device for door outer handles of a motor vehicle in which a arranged on the handle part pivotable element is provided with a toothing, which cooperates with a fixedly provided on the housing part blocking element, when the pivotable element in a side impact, a pivoting movement performs.
  • this known locking device does not allow safe unlocking when the door is to be opened after a side impact.
  • a locking device for an outside door handle in which a mass-equipped locking element in a side impact is linearly deflected against the force of a spring, wherein the locking element engages simultaneously in recesses of the housing part and the handle part.
  • the locking element retaining springs In order to prevent a lock in normal operation, the locking element retaining springs must apply a relatively high bias, so that in case of a side impact, the blocking element operates against this spring force. Since at the same time a pivotal movement of the handle part is used in a side impact, a reliable operation of the locking device is not guaranteed. Furthermore, even a slight tilting between the grip part and the housing part is sufficient to prevent unlocking of the locking device after a side impact.
  • the invention is therefore an object of the invention to provide an outside door handle of the type mentioned above, and a method for automatically locking the pivotal movement of a handle portion, in which a blocking of the pivotal movement of the handle portion and after a side impact, a reliable automatic unlocking is possible in a side impact.
  • the invention advantageously provides that the impact pulse in a side impact is used to pivot the mass element and thus to displace the blocking element coupled to the mass element such that a movement of the grip part during the deflection of the mass element is temporarily prevented.
  • the mass element due to gravity and / or spring force returns to its original position, whereby automatically returns to the mass element coupled to the blocking element returns to its original position and thus the movement of the handle part is unlocked.
  • the blocking element is preferably displaced such that a possibly already covered path of the grip part due to the inertia of the grip part is taken into account.
  • the blocking element consists of a spring element bent in a plane, wherein the pivotable mass element brings the spring element in a side impact in an extended position in which projects at least one end of the spring element by a predetermined path. It is possible to use a spring element which is stretched in the extended position. When the spring element is relaxed in its bent position, there is the advantage that the release after a side impact is not only caused by the force acting on the mass element gravity, which generates a restoring moment, but is additionally supported by the spring force.
  • the mass element is preferably pivotable about a pivot axis which is substantially parallel to the axis of the handle portion and parallel to the door.
  • This axis can be mounted in the housing part, wherein particularly advantageously the mass element can be pivotable about the axis of the handle part.
  • the mass element preferably consists of a massed lever element which is coupled to the blocking element at the free end.
  • the blocking element can be displaced by the force of the pivotable mass element and automatically reset when the force is removed.
  • the displacement of the locking element takes place transversely to the side impact, preferably substantially parallel to the axis of the handle part.
  • the spring element can be transferred during the pivoting movement of the mass along a guide in the inclined position.
  • the guide is particularly advantageous in a wire-shaped spring element, since the guide prevents rotation of the spring element.
  • the bent spring element is held in a predetermined plane and is mounted in the region of its ends linearly movable in brackets.
  • the serving as a lever element mass element is preferably coupled in the middle between the brackets with the spring element.
  • the blocking element can also consist of a slider-crank mechanism in which the pivotable mass element drives at least one push element serving as a blocking element, which locks the handle part with a free end when the mass element is deflected. It can be provided, for example, that on both sides of the mass element acting as a lever element, two spring elements are articulated, which allow in the manner of a sliding-crank mechanism with their ends blocking the handle part. Again, the spring elements are brought by the pivotal movement of the mass elements in an extended position in which they have a maximum length.
  • the at least one end of the locking element engages in a side impact either in the handle part, or in the direction of movement of the handle part in front of the handle part, in order to lock a pivoting movement of the handle part.
  • a side impact either in the handle part, or in the direction of movement of the handle part in front of the handle part, in order to lock a pivoting movement of the handle part.
  • an optionally already covered path of the grip part as a result of the side impact can be taken into account in an advantageous manner.
  • a pivotally mounted and coupled to a locking element mass element is pivoted in a side impact and thereby the locking element is displaced such that a pivoting movement of the handle portion temporarily during the period the deflection of the pivotable mass element is blocked.
  • the blocking effect is therefore only during the deflection of the pivotable mass element, so that the locking device immediately immediately releases the handle immediately after a side impact.
  • the in Fig. 1 shown outside door handle comprises a fastened to the door of a motor vehicle housing part 2, in which a handle part 6, here a folding handle, about an axis 4 for opening the door via pivot arms 12 is pivotally mounted.
  • a lock coupling bracket 24 is pivoted, which is connected to a not shown Lock the locking device of a motor vehicle is coupled to open the door.
  • a mass member 10 is pivotally mounted in the middle between the axle bearings 15, which performs in a side impact due to the inertia pivotal movement outwards in the arrow direction.
  • the mass element 10 is provided with an eccentrically arranged mass, or as shown in the drawings, widening with increasing distance from the axis 4, so that the center of gravity of the mass element 10 has the largest possible radial distance from the axis 4.
  • the mass element 10 has a substantially triangular shape.
  • a blocking element 14 is articulated, which consists of a spring element bent in a plane.
  • the locking element is brought in a side impact by the movement of the mass element 10 and the coupling with this mass element in an extended position, whereby the blocking element 14 extends in the transverse direction to the direction of movement of the mass element 10.
  • the mass element 10 acts as a lever element on the blocking element 14 and can due to the inertia of a high force on the from a Apply spring element existing blocking element to bring this with the least time delay in the extended position.
  • the preferably on a spring wire existing spring element is transferred along a ramp-like guide 17 in the extended position.
  • the ramp-like guide may consist of two webs, as in Fig. 2 shown to receive the mass element 10 between them and thus fix the axial position of the mass element 10 on the axis 4.
  • the blocking element 14 is mounted in the region of its ends 20 linearly movable in holders 16, which are arranged at a distance from a pivot arm 12 of the handle part 6.
  • the holders 16 can be arranged such that a path of the swivel arms 12 of the handle part 6, which has already been covered, possibly due to the side impact, can be taken into account.
  • the acceleration of the grip part 6 can be reduced in the event of a side impact, so that the ends 20 of the blocking element 14 can stop the pivoting movement of the grip part 6 in a timely manner ,
  • the mass element 10 is preferably pivotable against the action of gravity. This has the consequence that after elimination of the shock pulse due to the side impact, the mass element 10 returns to its initial position due to gravity.
  • the mass element 10 acts in its acceleration due to the side impact against the spring force of the tensioned in the extended position blocking element 14 and is therefore supported in the unlocking of the locking device by the spring force.
  • the bias of the spring element may be low, wherein it is sufficient that the spring element holds the mass element 10 in its rest position.
  • the locking device described can therefore lock in a side impact due to the inertia of the mass element 10, a movement of the handle part 2 quickly and only for the duration of the deflection of the mass element 10. Once the shock pulse due to the side impact is completed, the mass member 10 returns to its original position, whereby the handle part 6 is unlocked and the door can be opened.
