Definitions
- the invention relates to an outer 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.
- mass barriers are known, with which it can be prevented that, in the event of a side impact against a vehicle door, due to the impact on a door. acceleration of the outer door handle is swiveled and the door is opened.
- an automatic locking device for exterior door handles of a motor vehicle in which a pivotable element arranged on the handle part is provided with a toothing which interacts with a stationary locking element provided on the housing part when the pivotable element is at a pivotal movement in a side impact performs.
- this known locking device does not allow safe unlocking if the door is to be opened after a side impact.
- a locking device for an outside door handle in which a locking element provided with a mass can be deflected linearly against the force of a spring in the event of a side impact, the locking element simultaneously engaging in recesses in the housing part and the handle part.
- the springs holding the locking element have to apply a relatively high preload, so that in the event of a side impact the locking element works against this spring force. Since at the same time a swiveling movement of the large part also occurs in the event of a side impact, reliable operation of the locking device cannot be guaranteed. Furthermore, a slight tilt between the handle is sufficient! and the housing part to prevent unlocking of the locking device after a side impact.
- the invention is therefore based on the object to provide an outside door handle of the type mentioned, and a method for automatically locking the pivoting movement of a handle part, in which a blocking of the pivoting movement of the handle part and after a side impact a reliable automatic unlocking is possible in the event of a side impact.
- the locking device consists of a mass element pivotably mounted in the housing part, which performs a pivoting movement in the event of a side impact due to the inertia, and a locking element that is coupled to the mass element and for the duration of the pivoting movement of the mass element so It can be shifted that the locking element temporarily blocks the movement of the handle part.
- the invention advantageously provides that the shock pulse in a side impact is used to pivot the mass element and thus to displace the locking element coupled to the mass element in such a way that movement of the grip part during the deflection of the mass element is temporarily prevented.
- the mass element After the shock pulse ceases to exist, the mass element returns to its starting position due to gravity and / or spring force, as a result of which the locking element coupled to the mass element automatically returns to its starting position and thus unlocks the movement of the handle part.
- the locking element is preferably shifted such that a possibly already traveled distance d of the handle part due to the inertia of the handle part is taken into account.
- the locking element consists of a spring element bent in one plane, the pivotable mass element in the event of a side impact bringing the spring element into a stretched position in which at least one end of the spring element projects by a predetermined path. It is possible to use a spring element that is tensioned in the extended position. If the spring element is relaxed in its bent position, there is the advantage that the unlocking on one side is not only caused by the force of gravity acting on the mass element, which generates a restoring moment, but is also supported by the spring force.
- the mass element is preferably pivotable about a pivot axis which runs essentially parallel to the axis of the handle part and parallel to the door. This axis can be mounted in the housing part, it being particularly advantageous for the mass element to be pivotable about the axis of the handle part.
- the mass element preferably consists of a lever element provided with a mass, which is coupled at the free end to the locking element.
- the locking element can shift from the force of the pivotable mass element and automatically reset itself when the force is removed.
- the locking element is displaced transversely to the side impact, preferably essentially parallel to the axis of the handle part.
- the spring element can be converted into the inclined position along a guide during the pivoting movement of the mass.
- the guide is particularly advantageous in the case of a wire-shaped spring element, since the guide prevents the spring element from rotating.
- the bent spring element is held in a predetermined plane and is mounted in supports in the region of its ends so as to be linearly movable.
- the mass element serving as a lever element is preferably coupled to the spring element in the middle between the holders.
- the locking element can also consist of a thrust crank mechanism in which the pivotable mass element drives at least one thrust element which serves as a locking element and which locks the handle part with a free end when the mass element is deflected.
- a thrust crank mechanism in which the pivotable mass element drives at least one thrust element which serves as a locking element and which locks the handle part with a free end when the mass element is deflected.
- two spring elements are articulated on both sides of the mass element acting as a lever element, the ends of which enable the locking of the handle part in the manner of a thrust crank mechanism.
- the spring elements are brought into an extended position by the pivoting movement of the mass element, in which they have a maximum length.
- the at least one end of the locking element either engages in the handle part or projects in front of the handle part in the direction of movement of the handle part in order to block a pivoting movement of the handle part. In this case, a possibly already traveled path of the handle part due to the side impact can be taken into account.
- a mass element which is pivotably mounted and coupled to a locking element is pivoted in the event of a side impact and the locking element is thereby displaced such that a pivoting movement of the handle part is temporarily during the duration the deflection of the pivotable mass element is blocked.
- the locking effect is therefore only during the deflection of the pivotable mass element, so that the locking device automatically releases the handle immediately after a side impact.
- Fig. 1 an outside door handle in the rest position
- Fig. 2 shows an outside door handle in a side impact with activated locking device.
- the outer door handle shown in FIG. 1 comprises a housing part 2 which can be fastened to the door of a motor vehicle and in which a handle part 6, here a folding handle, is pivotally mounted about an axis 4 for opening the door via swivel arms 12.
- a lock coupling bracket 24 is pivoted, which with a not shown Lock of the locking device of a motor vehicle is coupled to open the door.
- a mass element 10 is pivotably mounted in the middle between the axle bearings 15 and, in the event of a side impact, executes a pivoting movement outwards in the direction of the arrow due to the inertia.
- the mass element 10 is provided with an eccentrically arranged mass, or, as shown in the drawings, is designed to widen with increasing distance from the axis 4, so that the center of gravity of the mass element 10 has the greatest possible radial distance from the axis 4.
- the mass element 10 has a substantially triangular shape.
- a locking element 14 is articulated, which consists of a spring element bent in one plane.
- the blocking element is brought into an extended position by the movement of the mass element 10 and the coupling with this mass element, as a result of which 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 locking element 14 and, due to the inertia, can exert a high force on it Apply the spring element to the existing locking element in order to bring it into the extended position with the least delay.
- the spring element which preferably consists of a spring wire, is transferred into the extended position along a ramp-like guide 17.
- the ramp-like guide can consist of two webs which, as shown in FIG. 2, accommodate the mass element 10 between them and thus fix the axial position of the mass element 10 on the axis 4.
- the locking element 14 is mounted in the region of its ends 20 in a linearly movable manner in holders 16 which are arranged at a distance from a swivel arm 12 of the grip part 6.
- the brackets 16 can be arranged such that a path of the swivel arms 12 of the handle part 6 that may have already been covered due to the side impact can be taken into account.
- a countermass 26 serving as a mass lock is arranged on the side of at least one swivel arm 12 opposite the axis relative to the axis, so that the acceleration of the handle part 6 in the event of a side impact can be reduced, so that the ends 20 of the locking element 14 can in any case stop the swivel movement of the handle part 6 in good time ,
- the mass element 10 is preferably pivotable against the action of gravity. As a result, after the impact pulse ceases to exist due to the side impact, the mass element 10 returns to its initial position due to gravity.
- the Masscnclement 10 acts during its acceleration due to the rare impact against the spring force of the locking element 14 tensioned in the extended position and is consequently supported by the spring force when unlocking the locking device.
- the preload of the spring element can be slight, it being sufficient for the spring element to hold the mass element 10 in its rest position.
- the locking device described can therefore block a movement of the force element 2 quickly and only for the duration of the deflection of the mass element 10 due to the inertia of the mass element 10.
- the mass element 10 returns to its starting position, whereby the G ⁇ ffte ⁇ l 6 is unlocked and the door can be opened.
- Figs. G ⁇ ffte ⁇ lc shown are folding handles, but it goes without saying that the locking device described can also be used on exterior door handles with pull handles.
