Description

Device for operating a tailgate

lock The invention relates to a device for actuation a tailgate lock according to the preamble of claim 1.

A central locking system is known for locking all vehicle doors to be provided, by means of which all other locks are locked by pressing a lock will. If the central locking system is unlocked, all door locks including the tailgate lock can be unlocked in the usual way.

It is also known the operating mechanism for the tailgate lock removed from the tailgate lock, e.g. B. in the right rear light unit or in to provide a door pillar.

The disadvantage of these actuators is that they usually have Bowden cables or linkage work. If such an actuator is defective, one is repair difficult due to the distance to the castle.

There is also the risk of these actuating devices Damage to the fingernails, as they are mostly aligned with the body are.

It is therefore the object of the present invention to provide a device to operate a tailgate lock, with which a simple and Safe unlocking of the tailgate lock from anywhere in the vehicle is made possible.

This object is achieved by the invention characterized in claim 1 solved.

The device according to the invention comprises in the usual way a tailgate lock, consisting of a latch and one that can be brought into engagement with the latch Pawl, the pawl connected to the core of an electromagnet and wherein a solenoid energizing circuit is provided.

Such a device allows comfortable operation of the Tailgate lock, the device being designed to be very space-saving can. Furthermore, the device enables a stylistically optimal design the tailgate, as the usual release button can be omitted. Compared to the known, above-described actuating devices removed from the tailgate lock the device according to the invention does not require any complicated deflections and permits an arrangement for actuation even when the lock and push button are attached to each other moving parts must lie.

Advantageous refinements of the invention emerge from the subclaims.

Thus, the device can in an advantageous manner through the arrangement of the actuation button within the vehicle conveniently operated from the vehicle seat will.

The arrangement of the operating switch is also outside the Vehicle conceivable at a suitable location.

According to claim 4 is in a further advantageous embodiment of the invention provided to arrange them in connection with a central locking system, this being the case only requires a small additional effort.

In a further advantageous embodiment of the invention, there is Possibility of using the individual circuits described above to excite the electromagnet to be provided in any desired combination, the outside of the vehicle arranged switch is expediently designed as a switch lock.

This switch lock can have two switch positions, one first switching position for closing the circuit assigned to the central locking system and a second switching position is provided for closing a circuit, which bypasses the circuit associated with the central locking system.

Embodiments of the invention are shown in the drawing and are described in more detail below.

1 shows a first exemplary embodiment of the invention; Fig. 2 shows a second embodiment of the invention; 3 shows a third Embodiment of the invention; and FIG. 4 shows a combined exemplary embodiment the invention.

The device for operating a tailgate lock comprises in known way the tailgate lock 10, for example consisting of a spring-loaded Closing latch 12 and a spring-preloaded one that can be locked with the closing latch 12 Locking pawl 14. One end of the locking pawl 14 is connected to the core 15 of an electromagnet 16 connected, the pawl 14 against the bias of the in the excited state Spring 18 pulls out of the locked position with the latch 12, whereby the The tailgate of the vehicle is opened. To excite the electromagnet 16 is a circuit 20, 24, 28 is provided.

In a first embodiment of the device the circuit is 20 with a switch arranged inside the vehicle, e.g. on the dashboard 22 provided, which is used to open the tailgate, d. H. to excite the electromagnet 16, can be operated in a simple manner. If so desired, this can Switch according to a second embodiment as switch 32 outside the vehicle be arranged.

In a third embodiment of the device the circuit is 24 arranged in parallel with a central locking circuit 26. In this embodiment Unlocking the tailgate is only possible when the central locking system is unlocked.

The three embodiments described can of course be in any one Can be combined with each other in a manner as shown in Fig. 4, for example.

The first circuit 20 can be seen with that arranged in the vehicle Switch 22 to which the central locking system is connected in parallel Circuit 24 arranged with a switch 30 arranged outside the vehicle is. Another circuit 28 is provided in parallel to these two circuits a switch 32 arranged outside the vehicle.

The switches 30, 32 arranged on the outside are expediently made from one unit and can be operated by means of a switch lock 34. The outside arranged switch lock 34 accordingly has two switching positions for closing of the circuits 24 and 28 respectively.

The apparatus described in connection with Fig. 4 operates as follows.

If it is intended to open the tailgate lock, there is to one the possibility of the tailgate lock by means of the inside of the vehicle arranged switch 22 to unlock.

On the other hand, there is the option of unlocking the central locking by actuating the switch lock 34 and the switch 30, the tailgate lock to unlock.

When the central locking is locked, the switch lock 34 is through Turning the key associated with the switch 32, causing the tailgate lock can be unlocked by bridging the central locking.

It is understandable that there are also other possible uses of the device are self-evident to a person skilled in the art. For example, the device can advantageously be connected to an electrical anti-theft device.
