Description

[0001] The invention relates to a locking device, in particular for the passenger door of a motor vehicle.

[0002] In the case of motor vehicles, it is known that in older vehicles each door is provided with a lock and a cylinder to unlock or lock the respective door with a key.

[0003] It is also known that in older vehicles with central locking, only the driver's door is equipped with a lock cylinder for locking and unlocking with a key. The locking mechanism of the driver's and passenger's doors is at least essentially identical, except that the driver's door has a lock cylinder, while the passenger's door does not.

[0004] By omitting the lock cylinder on the passenger door, a space is created in the area of ​​the passenger door's locking mechanism that, in the event of manipulation, could be accessed with a tool to forcibly open the passenger door. A tool could, for example, penetrate this space through the gap in the window or through a hole made in the door panel or outer wall, allowing the locking mechanism to be manipulated to open the door. These manipulation attempts should be made as difficult or as impossible as possible.

[0005] DE 10 2011 002 287 A1 discloses a handle for a movable part of a motor vehicle, wherein a locking element is provided which can be arranged on an outer panel of the movable part to increase burglary protection.

[0006] DE 10 2004 001 894 A1 discloses an actuating device for doors, wherein a tower is provided which may have a locking cylinder or a styling dummy.

[0007] The object of the present invention is to create a locking device which is improved with regard to manipulation.

[0008] The problem is solved using the features of claim 1.

[0009] One embodiment of the invention relates to a locking device for a door, in particular for the passenger door or any other door of a motor vehicle, comprising a locking bridge attached to the door. The locking bridge has an opening into which a locking cylinder is inserted, or optionally, no locking cylinder is inserted. A security element is inserted between the door and the locking bridge, the security element having a projection that engages in the opening. The security element is made of a plastic material. By arranging the security element, the space in the area of ​​the locking bridge and between the locking bridge and the door can be filled, thus preventing the easy insertion of a tool to manipulate the locking components of the locking device.Inserting the projection into the opening also prevents the safety element from being easily pushed away, because it is thereby positively connected to the locking bridge.

[0010] In one embodiment, it is advantageous if the safety element is made of a foam material. This makes it easy to manufacture, lightweight, yet still stable.

[0011] It is particularly advantageous if the security element is made of a rigid foam material. This makes it especially robust in its ability to withstand tool strikes.

[0012] In another embodiment, it is advantageous for the security element to have a base body that is block-shaped and arranged between the door and the strike plate. This fills the volume of the free space, allowing the security element to bear against the door and the strike plate over a flat surface and preventing it from being easily pushed aside.

[0013] It is also advantageous if the base body at least partially surrounds the closing bridge on the outside. This creates an additional holding effect.

[0014] It is also advantageous if the base body forms at least a tongue that partially surrounds the locking bridge on the outside. This also ensures a good, form-fitting connection.

[0015] It is particularly advantageous if the tongue grips the top of the locking bridge, overlapping it. This effectively deflects attacks with tools from above and simultaneously makes it more difficult to shift the base body.

[0016] It is also advantageous if the tongue projects parallel to the projection on the base body. This further improves the positive locking connection.

[0017] The invention will now be explained in detail using an exemplary embodiment and with reference to the drawing. The drawing shows: Fig. 1 a schematic representation of a locking device on a door of a motor vehicle with a safety element according to the invention.

[0018] The Fig. Figure 1 shows a locking device 1 of a door 2, in particular a passenger door or any other door of a motor vehicle. The door can be a rear door of the motor vehicle or a front door, such as the passenger door.

[0019] Such locking devices have a locking bridge 3 which is attached to the inside of the door 2.

[0020] In this case, the locking bridge 3, for example, when used on the driver's side, is equipped with a locking cylinder inserted into an opening 4, which can be operated with a key.

[0021] On the passenger side or on another door, see Fig. 1, no lock cylinder is inserted into opening 4 because the locking bridge is typically used the same for both use with and without a lock cylinder.

[0022] It can be seen that a safety element 5 is inserted between door 2 and locking bridge 3, which has a projection 6 that engages in the opening 4 and in particular also extends through the opening, so that the projection 6 exits the opening 4 again.

[0023] Security element 5 is made of a plastic material, specifically a foam material, and in particular a rigid foam material. This makes it well-suited for preventing tampering with tools.

[0024] In Fig. Figure 1 also shows that the safety element 5 has a base body 7, which is block-shaped and is arranged between door 2 and locking bridge 3.

[0025] In an advantageous embodiment, the base body 7 at least partially surrounds the locking bridge 3 on the outside. It is also advantageous if the base body forms at least one tongue 8 which at least partially surrounds the locking bridge on the outside, as described above.

[0026] It can be seen that the tongue 8 projects parallel to the projection 6 from the base body 7. Reference symbol list 1 locking device 2 doors 3 Locking bridge 4 Opening 5 safety element 6 lead 7 Basic shapes 8 Tongue
