DE102008034649A1 - External door handle for vehicle, has blocking element locking handle component based on inertness of mass of blocking element in case of crash, and housing-like cover covering blocking element at region of bearing and/or motion axle - Google Patents

Abstract

The handle has a manually actuated handle component acting on a lock provided in a door during actuation. A pivotably supported blocking element is provided in an inoperative release position and actuates the handle component. The blocking element attains an effective locking position, and locks the handle component based on inertness of mass of the blocking element in case of a crash. A housing-like cover (30) covers the blocking element at a region of a bearing and/or motion axle. The blocking element is arranged in a fixing element e.g. bearing bracket.

Description

The The invention relates to an outside door handle, in particular for vehicles specified in the preamble of claim 1 Art. Such outside door handles are diverse Use. In a crash, especially with a strong side impact It is important to prevent the handling vehicle doors from passing through pivot the released forces outwards and thus open the vehicle doors. hereby there would be a risk that the vehicle occupants or Objects in the vehicle are thrown out of the vehicle become. In the prior art, therefore, are pivotable locking members suggested which due to the inertia of their mass be deflected before it comes to a deflection of the handle and then block an effective operation of the handle and so avoid unwanted opening of the vehicle doors.

Such a mass barrier describes, for example, the EP 1 050 640 A2 , Here an outside door handle for vehicles is described, which identifies a pendulum-like locking member. In the event of a side impact this locking member is deflected, thereby preventing effective operation of the handle.

Also the DE 199 29 022 A1 describes such an outside door handle. Here also a pivotable locking member is provided, which is deflected in the event of a crash and then prevents unintentional actuation of the handle.

adversely in these as well as in other arrangements known in the art However, the devices pollute over the years can. In a crash case is then under circumstances a safe deflection of the locking member is not given and the relevant Door opens unintentionally.

task The invention is therefore an outside door handle to provide the type specified, in which the locking member protected in particular in the area of its storage of contaminants becomes. This task is characterized by the characterizing features of Claim 1, the following special meaning due.

According to the invention a housing-like cover is provided which the locking member covering, and in particular in the area in which the locking member with its bearing or with its axis of motion is in communication. This area must be particularly protected against contamination, because here is a blockage of the pivoting movement of the locking member especially can easily occur and then has the consequence that the locking member in cash case no longer reliably convertible into its locked position is.

advantageously, should the locking member on a fixed element, which in the Operation of the handle not moved, be arranged. When Fixelement offer, for example, a bearing bracket or a handle support. These components are at an outside door handle usually present as they serve the door handle in the door to attach and store.

In In an advantageous embodiment, the cover formed integrally with the fixed element. Especially advantageous Here is the formation of the fixed element together with cover by injection molding. Depending on the application, but it is also cheaper, the Cover to secure the fixed element. Here are solvable Mounting options, such as detent or clip connections or a tightening, on. Alternatively, you can see the cover also attach permanently to the fixation element. Among the unsolvable Mounting options are recommended, for example Adhesive, welded or riveted joints.

In A particularly preferred embodiment is a Blocking lever provided. This will be during normal operation the handle moved. In the event of a crash, however, just this movement the blocking lever prevents the locking member, which also causes the handle can not be moved and the door does not open unintentionally. In a particularly preferred embodiment, the Blocking lever at least partially covered by the cover. So also soiling and consequent blockages in the field of guidance and / or storage of the blocking lever or be avoided in the effective range of the blocking lever with the locking member.

In a particularly preferred embodiment, at least one positioning element is provided, which acts on the locking member in the event of a crash such that it allows movements of the locking member in its pivoting plane, but on the other hand prevents movements of the locking member outside its pivoting plane. A further positioning element can also be provided for the blocking lever, wherein in the event of a crash the movements of the blocking lever in the plane of movement are also permitted outside the movement plane, however. This can ensure that both the locking member and possibly the blocking lever can only move in the desired direction. Movements in an undesirable direction through which canting can occur or whereby a safe action of the locking member or a secure interaction between the locking member and the locking lever verhin is avoided are avoided. This functionality can be realized in a particularly simple and reliable manner by arranging the or the corresponding positioning elements, which act on the blocking member or the blocking lever, such that the effective direction of the relevant positioning element is perpendicular to the pivot plane of the blocking member or to the plane of movement of the blocking lever runs. As a result, the movements of the locking member in the pivot plane and the blocking lever in the plane of movement are possible. Movements of the locking member or the blocking lever in a different direction, which is not in the pivot or movement plane, but are locked by the relevant positioning.

In A further preferred embodiment is the locking member spring loaded, wherein the spring load ensures that the locking member normally remains in its release position. hereby it is avoided that the locking member by normal movements of the Vehicle, for example when driving around a curve, from his Release position is deflected into one of its locked positions and so on Operating the handle and opening the door are no longer possible. It is also important that After a crash, people open the vehicle door from the outside can, for example, injured or trapped vehicle occupants or To free children from the vehicle. The spring load therefore provides also recommendable that after a crash and after the decay of the vibrations caused by this crash the locking member transferred back to its release position so that the doors can be opened.

Further Embodiments and advantages of the invention will become apparent from the following description, the dependent claims and the drawings. In the drawings, the subject invention shown in two embodiments. Show it:

1 an outside door handle according to the invention with handle in perspective view without covering the locking member,

2 an enlarged section 1 .

3 the elements off 2 with cover

4 the elements off 3 with partially broken cover

1 shows an outside door handle according to the invention with a handle 10 , The outside door handle has a locking member 20 which is pivotable on the fixed element 11 , here a bearing bracket, is stored. The locking member shown here 20 has two locked positions, so it acts in crashes from different directions. It is of course also possible, a locking member 20 to provide with only one locking position.

The locked position is the interaction of the locking member 20 with the locking lever 12 produced. This locking lever 12 becomes during normal operation of the handle 10 with moves. In the event of a crash, the locking member locks 20 the movement of the locking lever 12 and thus also the movement of the handle 10 ,

Further details about the locking link 20 and locking lever 12 are 2 removable. You can see there the spring load 22 of the locking member 20 , This spring load 22 ensures that normally the locking member 20 remains in its rest position or is returned to a deflection in this.

A deflection of the locking member 20 ideally takes place in its pivoting plane 21 , which is indicated here. If the blocking lever moves 12 in his movement plane 13 , which is also shown schematically here, so the locking member 20 and the locking lever 12 co-operate in the event of a crash. The locking lever 12 moves partially rotatory in this embodiment.

It Of course, other directions of movement would be as well conceivable, such as purely rotational or purely translational.

The locking lever 12 is guided in his movements, here through the slotted guide 14 , The scenery tour 14 can be used as positioning element 41 Serve and so ensure that movements of the locking lever 12 only in the movement plane 13 possible are.

The 3 and 4 show the closer design of the cover 30 , The locking member 20 and the locking lever 12 are completely in this embodiment of the cover 30 covered. This ensures that the possibilities of movement of the locking member 20 and the locking lever 12 can not be impeded or impaired by contamination. Important in this context is that the locking lever 12 , in particular in the area of its slotted guide 14 and the locking member 20 , in particular in the region of its axis of motion 23 , from the cover 30 are covered, since in these areas contamination has a particularly critical effect on the functioning of the device. Will the locking lever 12 otherwise guided or has a different axis of motion, so this should preferably also under the cover 30 are located. The same applies to the locking member 20 ,

Out 4 it can be seen that the positioning means 40 . 41 integral with the cover 30 are executed. Thus, the positioning means 40 . 41 particularly easy and inexpensive to attach to the device.

Finally It should be noted that the embodiments shown here are merely exemplary implementations of the invention. These is not limited to this. Rather, many variations and modifications possible.
