    Description

    [0033] Hereinafter the invention is explained in further detail with reference to the attached drawings on the basis of a preferred exemplary embodiment. However, the principle applies that the exemplary embodiment does not restrict the invention but only constitutes an advantageous embodiment. The characteristics depicted can be executed individually or in combination, individually or in combination with other characteristics of the description, as also the patent claims.

    [0034] The following are shown:

    [0035] FIG. 1 a three-dimensional view of a device with an axially fixed end of a Bowden cable in an embodiment in a motor vehicle latch housing, and

    [0036] FIG. 2 a magnified three-dimensional view of the housing with a Bowden cable inserted into a mounting of the housing.

    [0037] FIG. 1 depicts a device 1 having a housing 2, a Bowden cable 3 and an activation lever 4. The housing 2 is part of a motor vehicle latch housing executed in at least two parts in which an activation lever 4 is pivotably accommodated. The activation lever 4 can be moved in the direction of the arrow P by means of the Bowden cable 3.

    [0038] The Bowden cable 3 has a Bowden cable cover 5, a Bowden cable seal 6 (seal collar), a Bowden cable core 7 and a connecting element 8 pivotably connected to the activation lever 4. The Bowden cable 5 also has a flange 9 and an additional sheathing 10 for the Bowden cable cover 5. The housing 2 is made of plastic and has a mounting 11 and an insertion means 12, whereby the mounting 11 and the insertion means 12 in this exemplary embodiment are formed as a single component with the housing 2. Further reinforcement ribs 13 can be provided for in the housing 2.

    [0039] The flange 9 of the Bowden cable cover 5 has a larger diameter than the diameter of the Bowden cable cover 5. In turn, the mounting 11 has a recess 14 into which the flange 9 of the Bowden cable cover 5 is inserted. The recess 14, into which the flange 9 is inserted or pushed radially secures the Bowden cable cover in relation to the housing 2. The insertion means 12 envelops the Bowden cable cover 5 at least in part, whereby the insertion means 12 extends along the opening 15. The insertion means 12 extends along a lengthwise axis L of the Bowden cable 5 and thus additionally braces the Bowden cable cover 5. In one embodiment, the sheathing 10 can additionally be braced on the insertion means 12. i.e. where the flange 9 is inserted completely into the recess 14 of the mounting 11, the additional sheathing 10 is adjacent to the insertion means 12.

    [0040] In FIG. 2, an enlarged illustration of the connection area 16 of the Bowden cable is also reproduced on the device 1 in a three-dimensional illustration. The same components are equipped with identical reference signs. The recess 14 in the mounting 11 is clearly apparent into which the flange 9 of the Bowden cable cover 5 is pushed in and held in a play-free manner. In the embodiment illustrated in FIG. 2, the insertion means 12 is molded on the housing 2 and forms a bevel 17. The bevel 17 extends from the ends 18, 19 of the opening 15 along the circumference of the opening 15. The bevel 12 envelops the Bowden cable cover 5 at least in a form-fitting manner in part.

    [0041] During mounting of the Bowden cable 3, the Bowden cable cover is led to the housing 2, whereby an installer can push against the insertion means 12 and in particular against the bevel 12 with the flange 9 of the Bowden cable 3. An insertion of the Bowden cable on the housing and in particular on the insertion means 12 can be prevented by the bevel 17 as the flange 9 slides off the bevel 17 and cannot be fixed. It is only possible for the installer to insert the flange into the mounting 11 when the flange 9 reaches the insertion area 20. The insertion means 12 thus effectively prevents incorrect mounting of the Bowden cable. The Bowden cable 3 can therefore not be fixed incorrectly, whereby safe mounting can be guaranteed. The Bowden cable 3 can only be activated in the adjacency in the mounting 11 so that the activation lever 4 can be activated in the direction of the arrow P by pulling on the Bowden cable core 7, for example.

    [0042] The illustrated exemplary embodiment can, for example, be a housing 2 for a motor vehicle latch, and the activation lever 4 can, for example, act directly on a locking mechanism in the motor vehicle latch.

    [0043] The illustrated exemplary embodiment shows the mounting of a Bowden cable 3 in a latch housing in only a part of the latch housing 2. A non-illustrated housing lid has an extension which can be pushed into the insertion area 20, whereby the flange 9 of the Bowden cable cover 5 is secured and fixed in the housing 2.

    [0044] The flange 9 on the Bowden cable cover 5 has an axial end 21 of the Bowden cable 3 which becomes adjacent in the depression 14 of the mounting 11. The Bowden cable seal 6, such as a sealing collar, for example, can be connected to an extension piece extending through the mounting 11 with the Bowden cable 3. Such Bowden cable seals 6 are known from the state of the art.

    [0045] The formation of a device according to the invention with an insertion means 12 can enable safe mounting of a Bowden cable 3 and prevent incorrect mounting.
