Technical Field

The invention relates to a Bowden cable system for a motor vehicle lock. The invention also relates to a vehicle lock with a bowden cable system.

Background

In the transmission of mechanical movements, it may be expedient for the movements to be transmitted from different initial points to a specific point. An example of this is disclosed by publication DE 102007005814 a 1.

In order to be able to pass from two initial points to a specific point, two ropes are provided according to the publication DE 102015105066 a1, which run in the casing and connect the respective initial point to the specific point.

Disclosure of Invention

The aim of the invention is to transmit movements from different starting points to a specific point with little technical effort, whereby no straight-line connection between the starting points and the specific point is required.

This object is achieved by a bowden cable system having the features of claim 1. The dependent claims relate to a locking system for a vehicle with a bowden cable system.

The motor vehicle lock of the motor vehicle locking system can have a locking mechanism and a release lever for the locking mechanism within the scope of the invention. If the release lever is rotated, the latching mechanism is thereby opened. Subsequently, the respective vehicle door or vehicle cover can be opened.

Furthermore, the locking mechanism may have a rotary jaw and a pawl for locking the rotary jaw in the closed position. In the locked position, the turning pawl holds the door or lid latch. By releasing the lever, the pawl can be moved out of its locked position. After this removal movement, the rotary latch can be pivoted into its open position. If the rotary jaw reaches its open position, the bolt can be moved away from the rotary jaw and the corresponding door or cover opened.

The bowden cable transmits mechanical motion from an initial location to a designated location by means of a cord extending within the sheath. The sleeve is constructed of an incompressible or nearly incompressible material, so that the sleeve retains its shape in the tightening direction or the pressing direction. The sleeve may be constructed wholly or partially of metal. Otherwise the sleeve is pliable. To transmit the mechanical movement, the cord is moved relative to the sleeve. Because of the sleeve, a straight line connection between the two locations is not required to transmit motion. Thus, the bowden cable can advantageously be used in a vehicle locking system in order to be able to transfer an opening movement from a handle of the vehicle locking system to a lock of the vehicle locking system, for example.

The rope is also advantageously made of an incompressible or practically incompressible material in order to be able to transmit also pressure forces. Thus, the rope may be a wire rope.

According to the invention, the bowden cable system comprises at least two bowden cables which are connected to the connecting element such that they can transmit movements from an initial location to the connecting element. The link is in turn connected to a bowden cable so that the movement of the link can be transmitted to a designated location. The designated location advantageously only needs to be connected to one bowden cable. The length of each bowden cable may preferably be short.

Advantageous refinements and improvements of the invention are given in the dependent claims and in the description. It is to be noted that the following embodiments for illustrating the invention are not limitative, but instead lead to many combinations and modifications of the features for implementing the invention as described in the description, the drawings and the dependent claims. The features and details described in connection with the device according to the invention are obviously also applicable in connection with the system according to the invention, so that in connection with the disclosure with respect to the inventive aspects always or possibly with respect to each other.

In an advantageous embodiment, the first and second bowden cables are connected to the connecting element, so that the connecting element can be moved along the cables of the first and second bowden cables. If a mechanical movement is to be transmitted from the first initial location to the connecting element via the first bowden cable, it is necessary in this embodiment that the second bowden cable advantageously does not follow the movement. Thus, a trouble-free operational use can be better achieved.

In an advantageous embodiment, a third bowden cable is fixedly connected to the connecting element. The pulling force can then be transmitted from the initial point to a specific point in a technically simple and reliable manner.

In an advantageous embodiment, the first and second bowden cables extend through the connection member and each end of the passage comprises a widening. In a technically simple manner, it is thus possible for the connecting element to be moved along the cables of the two bowden cables, so that a trouble-free operational use can be achieved in a technically simple manner. The widening prevents the cable of a bowden cable from being pulled out of the connecting element. Otherwise, the tensile force cannot be transmitted.

In an advantageous embodiment, the elastic element connects one end of the first or second bowden cable with an end wall of the housing. The elastic member may be an elastic wire or a spring. By means of this embodiment, a further improved assurance of non-interfering operational use is achieved.

The subject of the invention is also a vehicle locking system with the bowden cable system according to the invention. In such locking systems, on the one hand, usually only a small amount of installation space is available. On the other hand, it is necessary to transfer the motion from a different initial location to a designated location. Furthermore, no straight-line connection is generally available, so that the invention is advantageous for a vehicle locking system, since a small installation space can be used to transmit movements from many different initial points to a specific point, in particular to transmit tensioning movements.

In such a vehicle locking system, the third bowden cable is preferably connected to a release lever, by means of which the locking mechanism can be opened. The bowden cable system is then used to open the respective door or lid.

The first bowden cable is advantageously connected to a drive device. The drive is in particular an electric drive in order to be able to electrically open the door or the lid. That is, the drive means may be, for example, an electric motor.

The second bowden cable is preferably connected to a handle. It may be an outer handle or an inner handle of a vehicle door. The respective door or cover in which the outer handle or the inner handle is turned can then also be opened manually by means of a bowden cable system.

If it is intended to be able to transmit the opening movement from the drive, the outer handle and the inner handle, a further bowden cable can be provided, which is connected to the connecting element and one of the starting points. That is, the present invention allows flexibility in adding an initial location so that motion can be transferred from the initial location to a designated location as needed.

The invention will be described in detail below with reference to the drawings and in connection with several preferred embodiments. It is again pointed out that the implementation of the invention is not limited to the embodiments shown, but that the embodiments shown are only advantageous implementations. The features shown may be advantageous alone or in combination with other features of the description and the claims. At this point it is noted that the drawings are merely illustrative of the nature and are not intended to limit the invention in any way.

Drawings

In the following embodiments, identical or equivalent components are denoted by the same reference numerals and repeated descriptions thereof are omitted, wherein:

FIG. 1 shows a Bowden cable system before motion transmission;

FIG. 2 shows the Bowden cable system after the movement has been transferred from the first initial location to the designated location;

fig. 3 shows the bowden cable system after the motion has been transferred from the second initial location to the designated location.

Detailed Description

Fig. 1 shows a bowden cable system according to the invention, whereby movement can be transmitted from an initial location a or B to a designated location C. The bowden cable system is in an initial position from which the tightening movement can be transmitted from one of the initial points a or B to the designated point C. The first bowden cable comprises a cord 1, which extends within a sheath 2. The second bowden cable comprises a cord 3 which extends within a sheath 4. The third bowden cable comprises a cord 5 which extends within a sheath 6. All bowden cables are connected at one end to a connecting piece 7. The first bowden cable with the cable 1 is connected to the starting point a, so that a movement, in particular a tensioning movement, can be transmitted from the starting point a to the connecting element 7 via the first bowden cable. The second bowden cable with the cable 3 is connected to the starting point B, so that movements, and in particular tensioning movements, can be transmitted from the starting point B to the connecting element 7 via the second bowden cable. The third bowden cable with the cable 5 is connected to the desired location C, so that a movement, and in particular a tensioning movement of the connecting element 7, can be transmitted to the desired location C via the third bowden cable.

The two ropes 1, 3 extend through the connecting element 7 and end in widened portions 8, 9. There is preferably a gap between each passage through the link and the rope 1, 3 passing through, so that the link can move along the respective rope 1, 3 with little friction. The diameter of the widened portions 8, 9 is greater than the passage through which the ropes 1, 3 pass through the connecting element 7. This connection results in the connecting element 7 being movable to the left in the situation of fig. 1 with respect to the rope 1 or 3. But the connecting piece 7 cannot move to the right beyond the widened ends 8, 9.

The rope 5 of the third bowden cable is fixedly connected with the connecting piece 7.

The ends with the widened portions 8, 9 can be connected to the adjoining end faces of the housing 12 by means of elastic threads 10, 11. The elastic thread can advantageously be pretensioned.

The sheaths 2, 4 of the first and second bowden cables end at one end face of the housing 12. The sheath 6 of the third bowden cable ends at the opposite end face of the housing 12, to which the optionally provided elastic wires 10, 11 are fixed. The connecting element 7 is movably arranged in the housing 12.

If a tightening movement is applied to the cable 1 of the first bowden cable at a first designated location a (indicated by the arrow in fig. 2), such a tightening movement is transmitted via the cable 1 to the connecting element 7. By this tightening movement the connecting element 7 is moved to the left, as shown in fig. 2. The movement of the connecting element 7 is transmitted to the designated location C by means of the rope 5. The cable 3 of the second bowden cable is practically not moved. If the widened end of the cord 3, i.e. the widening 9, is connected to one of the end faces by means of the elastic thread 10, this tensioning movement also has no effect on the position of the widened end 9.

If a tightening movement is applied to the cable 3 of the second bowden cable at a second designated location B (indicated by the arrow in fig. 3), such a tightening movement is transmitted via the cable 3 to the link 7. By means of such a tensioning movement, the connecting element 7 is moved to the left, in the case of fig. 3. The movement of the connecting element 7 will be transmitted to the intended site C by means of the rope 5. If the widened end 8 of the cord 1 is connected to one of the end faces by means of the elastic thread 11, the tensioning movement also has no influence on the position of the widened end 8.

By means of the invention, only one bowden cable is needed, which is connected to the designated location C in order to be able to transmit the movement to the designated location C. At the designated location C, it is therefore not necessary to provide an excessively large structural space in order to properly connect the designated location C to the bowden cable system. Other bowden cables can be connected to other initial points on one side and to the connecting element 7 on the other side, in order to be able to transmit the movement from other initial points to the designated point C as well.

Starting from the state shown in fig. 2 and 3, the tensioning movement at the designated point C results in a return to the initial position of fig. 1.

In an advantageous embodiment, the third bowden cable is connected (at the designated point C), in particular fixedly coupled, to a release lever 13 of the vehicle locking system, as shown in fig. 1. The first bowden cable is in one embodiment connected to a handle 14 (at an initial location a) of the door or cover as shown in fig. 1. If the handle 14 is operated, i.e. turned, as shown in fig. 2, the consequent movement of the handle 14 is transferred to the release lever 13, as shown in fig. 2, and the car lock, i.e. the locking mechanism of the car locking system, is opened. The second bowden cable can be connected (at the initial location B) to a drive means 15, in particular an electric drive means, as shown in fig. 1. If the drive means 15 is activated as shown in fig. 3, a tightening movement is applied to the second bowden cable, which is transmitted to the release lever 13. This then results in: rotation of release lever 13 as shown in fig. 3 unlocks the vehicle latch or locking mechanism. In this way, the other handle can be connected to the connecting element 7 via a fourth bowden cable, so that an actuation of the other handle leads to the opening of the vehicle lock. One of the handles may be an outside door handle. The other handle may be an in-door handle.

The foregoing description of the embodiments is provided to illustrate the invention by way of example only. It is obvious that individual features of the various embodiments can be freely combined with one another as far as technically expedient without going beyond the scope of the present invention.
