MOTOR VEHICLE DOOR

The invention relates to the field of motor vehicle doors and vehicle door locking systems. More particularly, the invention relates to a door provided with an anti-intrusion element.

The published patent document GB 2528747 A discloses a motor vehicle door locking mechanism. A latch on the mechanism engages the hook which is fixed to the body. When the door is locked, the movement of the latch is blocked in the engaged position by a blocking piece. When the door is unlocked, this blocking piece is moved to release the latch, which can therefore be disengaged from the hook, under the action of the door latch. The latch and the locking piece are assembled, with all the other parts of the lock, on a support piece. If the blocking piece is accessible to a potential thief, he can unlock the door. The document in question therefore suggests grafting an anti-intrusion metal cover onto the stirrup. This design is complex and expensive. In addition, if a vehicle has several caliper models or if a manufacturer develops calipers of different geometries, the geometry or the dimensions of the cover must be adapted, which limits the flexibility of such a system.

The patent document FR 2 873 734 describes a mechanism for locking the door of a motor vehicle. A link called "oar" transmits the rotational movement of the key to the lock. In order to ensure that the train cannot be reached by a flat clamp when the exterior window wiper is removed, the train is surrounded by a cylindrical sleeve which is free to rotate around the train. During a burglary attempt, the thief who attempts to manipulate the oar would therefore rotate the sleeve on itself without actuating the oar. This mechanism requires the manufacture and assembly of several parts. So it's an expensive and complex system.

The aim of the invention is to overcome at least one of the drawbacks of the above-mentioned state of the art. More particularly, the invention aims to provide a vehicle door provided with a locking system which is simpler, less expensive and which meets burglar-resistance standards, in particular Thatcham®.

The subject of the invention is a door of a motor vehicle comprising: an outer wall; an exterior door opening control handle, the handle comprising a latch and a door cylinder capable of receiving the vehicle key; the outer handle being mounted on the outer wall; a bracket arranged on the inner face of the outer wall and ensuring the movable mounting of the outer handle on said wall; a lock configured to cooperate with a strike on a fixed part of the vehicle body; a rod for controlling the lock by the door cylinder, extending transversely through the stirrup and pivotally mounted in the stirrup; an anti-intrusion device of the control rod; remarkable in that the burglar-proof device comprises a fixed wall and integral with the stirrup, said wall at least partially surrounding the control rod at the outlet of said stirrup.

Such a design of the protective element is simpler and less expensive than the known protective elements.

In an advantageous embodiment of the invention, the wall of the burglar-resistant device has a U-shaped profile receiving the control rod and open laterally or downwards. There is therefore at least one of the branches of the U which protects the control rod from above. By "above" is meant the upper side of the stirrup when it is mounted in the door taken in the normal direction of a door mounted on a vehicle. A U-shape allows easier mounting of the control rod by the open branch of the U. In an advantageous embodiment of the invention, the U-profile of the wall of the burglar-resistant device is open laterally towards the front of the vehicle.

In an advantageous embodiment of the invention, the wall of the burglar-proof device extends transversely from the stirrup to the lock at a distance of zero or less than 5 mm.

In an advantageous embodiment of the invention, the wall of the burglar-proof device is at a distance from the control rod greater than or equal to 5 mm and / or less than or equal to 25 mm.

In an advantageous embodiment of the invention, the wall of the burglar-proof device has an average thickness greater than or equal to 2 mm and / or less than or equal to 5 mm.

In an advantageous embodiment of the invention, the stirrup and the burglar-resistant wall are made of plastic injection, in one piece.

The invention also relates to the stirrup as such. This forms a support for an exterior handle for controlling the door of a motor vehicle, intended to be fixed to the interior face of the exterior wall of said door, said bracket comprising a transverse orifice intended to receive a control rod for a lock. from the door by the exterior handle; and remarkable in that it further comprises a wall extending transversely from the orifice so as to at least partially surround the control rod and serve as a burglar-resistant wall for said rod.

In an advantageous embodiment of the invention, the stirrup is generally extended in a longitudinal direction, the transverse orifice and the burglar-resistant wall being located at one end of said stirrup.

The stirrup in question is that of the door described above. It may include the technical characteristics described in combination with the door.

Finally, the invention relates to a motor vehicle provided with a door according to the invention or a stirrup according to the invention.

Other characteristics and advantages of the present invention will be better understood from the description and the drawings, among which:

- Figure 1 is a schematic sectional view of a door without burglary protection;

- Figure 2 is an isometric view of the conventional stirrup;

- Figure 3 is a schematic sectional view of the door according to the invention;

- Figure 4 shows an isometric view of the stirrup according to the invention with the burglar-resistant wall;

- Figure 5 shows a door according to the invention.

Figure 1 shows a schematic sectional view of a conventional door. The door 1 is equipped with an exterior wall 5. This wall supports the exterior handle 8, 9. The exterior handle is composed of a movable part 8, the latch, which is actuated to open the door. The handle also comprises a door cylinder 9 designed to receive the vehicle key. The cylinder 9 is rotatably mounted in its housing which is fixed in the outer wall 5 of the door 1. The latch 8 and the cylinder 9 are fixed on a support called stirrup 2. This stirrup 2 is fixed on the inside of the wall 5. By “interior”; means the interior side of the door taken in the normal direction of a door mounted on a vehicle.

The lock 3 is also mounted on the wall 5 on the inside but at a distance from the stirrup. The lock 3 cooperates with a keeper on a fixed part of the vehicle body.

When locking or unlocking the lock 3 manually, the user inserts the key in the door cylinder 9. Under the action of the key, the cylinder 9 rotates in its housing. The rotational movement of the cylinder 9 is transmitted to the lock 3 by a control rod 4 mounted free in rotation in the stirrup 2 and also free in rotation in the lock 3.

As shown in Figure 1, the control rod 4 can be accessed by a clamp P which would be introduced between the door wall 5 and the window 6 of the door. If necessary, the window wiper 10 can be removed to access the control rod

4. It is thus possible for a malicious person to unlock the vehicle, without using the key.

The solution envisaged in existing systems was to provide the control rod with a cylindrical sleeve free to rotate around the train. Pliers on the cylindrical sleeve would rotate the sleeve on itself without being able to rotate the control rod.

An example of a conventional stirrup 2 is shown in FIG. 2. The stirrup in particular comprises an orifice 2.1 which can accommodate the seat 7 of the control rod 4.

Figure 3 shows a door 1 according to the invention. The same reference numbers refer to the same technical elements.

The stirrup has a burglar-resistant wall 2.2 which extends substantially up to the lock, that is to say up to the lock or less than 5 mm from the latter. Thus, it is impossible for the potential thief to maneuver the control rod 4 using a clamp P introduced between the door wall 5 and the window 6.

The burglar-resistant wall 2.2 is shown in the isometric view in FIG. 4. In this embodiment, it is the contours of the orifice 2.1 which extend along the axis of the control rod 4. The stirrup is a injected plastic part. The wall is a shape that is part of the caliper body. In other words, the wall is in one piece, injected with the caliper and is not an attached part.

Figure 5 describes the door according to the invention without the lock. The bracket 2 is fixed to the door wall 5, interior side. The control rod 4 is positioned in its seat 7. The seat 7 itself being fixed in an orifice 2.1 of the stirrup 2. The burglar-resistant wall 2.2 in a general U shape covers the upper, lower and rear sides (seen in the direction of the door mounted on the vehicle) of the control rod 4. Thus, the activation of the control rod by a clamp which would be inserted between the front door and the rear door of the vehicle is also made impossible.

The wall 2.2 is at a distance from the control rod 4 greater than or equal to 5mm and / or less than or equal to 25mm.

The thickness of the wall 2.2 is between 2 and 5 mm.

The control rod 4 has two generally spherical shapes at its ends to provide a ball joint with the bracket and a ball joint with the lock. The control rod may have a flange and flats.
