"Device for preventing unauthorized use of a vehicle, in particular a motor vehicle"

The invention relates to a device for preventing unauthorized use of a vehicle, in particular of a motor vehicle, with a transmitter and with at least one lock actuated by a receiver and / or a warning device, whereby the transmission between transmitter and receiver in coded form by infrared light or the like via a fiber optic cable and the receiver and / or the lock and / or a unit that can be switched on or off by the lock in one Safety housing is or are arranged according to patent (patent application P 29 26 304.5).

The present invention was based on the object of a portable transmitter for an anti-theft device to design and arrange according to the main application in such a way that, with a simple construction, perfect operation is guaranteed with the simplest operation.

This object is achieved according to the invention in that the transmitter can be pushed into a receptacle arranged in the interior of the vehicle, and that on the outside of the transmitter at least one actuating element for triggering the transmitter signal is arranged, which by corresponding shape of the receptacle is forcibly actuated when inserting and removing the transmitter, and wherein the fiber optic cable opens in the region of the receptacle.

The receptacle is preferably arranged in the area of a glove box of the vehicle and from one Cover of the glove box covered, so that a closing of the lid a correct Binschubstellung the Sender ensures. A transmitter that is not fully inserted will be affected by the closing cover of the Applied glove box and so printed in its functional position, what the operational safety of a such device increases considerably.

In an advantageous embodiment of the invention it is provided that within the receptacle with the power supply of the vehicle related contacts are arranged with contacts on the outside of the transmitter cooperate. In this way, the transmitter is automatically connected to the vehicle's electrical system when it is inserted and is thus independent of the functioning of its own battery.

However, it can be advantageous if the transmitter also with a rechargeable battery preferably

low capacity, which is then used during the Is reloaded during driving. Such a solution has the advantage that the transmitter is also outside of his Vehicle-mounted recording can be used, namely preferably for locking the vehicle, for activating a separate warning system or for actuating electrically powered garage doors.

In a further embodiment of the invention it is provided that the actuator ζ. B. designed as a toggle switch, is formed that when inserting and removing the Transmitter from the recording different signals can be triggered. This is e.g. B. desirable when the signals for switching on and off to avoid incorrect switching e.g. B. in the presence of several Recipients should distinguish.

Finally, it is also advantageous if the contacts are arranged in such a way that they are closed when the transmitter is inserted before the transmitter is activated via the actuation element.

The subject matter of the invention is intended below with reference to an exemplary embodiment shown schematically in the drawing will be explained in more detail, the drawing being a horizontal section in the area of a dashboard arranged glove box of a motor vehicle shows *

In the area of an instrument panel 1 is a glove box provided ,, which is connected by a pivotable cover 3

is closable. Next to the glove box 2 is a Recording 4 arranged for a transmitter 5, which also through the closed lid 3 of the glove box 2 is covered. The transmitter 5 can and should be about the size of a pocket lighter be shaped so that it can only be pushed into the receptacle 4 in a certain position.

Within the receptacle 4, fixed electrical con tacts 6 are provided, which are connected via lines 7 to the electrical system of the vehicle are connected, and the contacts 8 arranged on the outside of the transmitter 5 together men affect to ensure the power supply of the transmitter 5.

The transmitter 5 is activated via a pushbutton 9i when inserting - and correspondingly when pulling out the Transmitter 5 is acted upon by a stationary cam 10. Via this push button 9, the transmitter 5 can also from Hand operated, provided that it also has its own power supply.

The encoded signals emanating from the transmitter are transmitted via a transmitter output 11 to a fiber optic cable 12, which is connected in a manner not shown to a receiver which, for. B. to a distributor, an injection pump, the vehicle battery or the like. Can act.

When the transmitter is inserted into the receptacle, the anti-theft device is switched off and when it is pulled out of the station from the recording, it is reactivated.

A particular advantage of the solution according to the invention is the fact that the transmitter is only inserted during insertion or while it is being pulled out of the receptacle, and in no way in the rest of the time of the vehicle intervenes, which significantly increases operational safety. The transmitter can also be used from outside the Recording directed at the input end of the fiber optic cable and the push button operated by hand. Even Finally, it is still conceivable when borrowing the vehicle or when visiting the workshop Leave the transmitter in its cradle and lock the glove box lid in order to decode the Transmitter to prevent.
