    [0001] The present invention relates to a lock for anti-theft steering column of a motor vehicle. The invention relates to the field of locks and locks for motor vehicle steering column intended in particular to control the unlocking of a steering column of the vehicle during ignition of the motor vehicle. It is known that steering column locks, comprising at least one stator, a rotor and a cam, can be maintained in very distinct positions thanks to different indexed angular positions: a neutral end angular position "Stop", in the antitheft locks the steering column, - an intermediate angular position "On", in which the vehicle is electrically powered, and allows the start of the engine of the vehicle, and - an active extremity angular position "Start" or "Start", in which in addition to the "On" functions, the starter is energized to start the engine of the vehicle. Of course, other positions may exist such as the intermediate angular position "Accessories", to electrically power some accessories, such as the radio, typically arranged between the neutral extremity angular position "Stop" and the intermediate angular position " Walk ". Once the engine is turned on, the antitheft is automatically returned from the "Start" position to the "On" position by a restoring force. The "On" position is the position used when driving the vehicle. It is known a mechanical indexing system that keeps the key / rotor / cam in a stable position as long as a voluntary action of the user does not change this position to, for example, turn off the engine while turning the key from the "On" position to the "Stop" position. The term "voluntary action -2-" of the user is called simply a rotation of the key against the indexing torque, for example of the order of 0.2 to 0.4 N.m. A first disadvantage of this type of lock is that the key can leave its indexed position in case of involuntary action of the type "knee in the key driving". In this case, the lock can then reach an angular position where the electrical functions "On" are no longer insured, and thus cause the accidental shutdown of the engine while driving. A second disadvantage of this type of lock is that during a motor start, because of the automatic return of the key in the "on" position by spring return, if the key is released suddenly without accompanying the hand of the position "Starting In the "On" position, the indexed "on" position may be exceeded due to the inertia of the key / rotor / cam assembly. The antitheft is then positioned in an unindexed (and not stable) angle. Therefore, the running vibrations can cause the lock in an angular position where the electrical contact "On" is lost, involving an involuntary shutdown of the engine. The present invention aims to avoid these security problems. For this purpose, the present invention proposes a lock for antitheft steering column of a motor vehicle comprising: - a stator comprising a stator head in which is formed an opening, - a rotor mounted to rotate relative to the stator around an axis and comprising an annular flange, - a cam intended to be integral in rotation with the rotor, - an elastic element arranged between the cam and the rotor for axially urging said thrust rotor, wherein the opening is shaped so that its cooperation with the annular flange blocks the rotation of the rotor in a predetermined direction of rotation from a predetermined angular position and allows rotation of the rotor beyond the predetermined angular position by depressing the rotor.
    [0002] Such a lock for antitheft steering column of a motor vehicle proposes a new kinematic rotor to move from the intermediate angular position "On" to the neutral end angular position called "Stop" -3- relative to the engine stop. Thus, when the antitheft device is in the "On" position, the user is obliged to push the key to perform the rotation towards the "Stop" position. If the key is not pushed, the rotation of it is impossible. Thus it is no longer possible in case of involuntary action of the type "knee in the key while driving" to remove the key from its indexed position causing the involuntary shutdown of the engine while driving. Likewise, it is no longer possible to cause the engine to stop unintentionally when the key is automatically returned to the "on" position by a restoring force, when the key is released suddenly without accompanying the hand of the position. Extreme angular activates "Start" in the "On" position. Thus, the lock of the invention allows a simple and very effective way to avoid the security problems of the prior art. According to preferred embodiments, the motor vehicle steering column antitheft lock according to the invention comprises one or more of the following features, taken separately or in combination: the annular collar comprises an extension extending axially towards the rotor head for receiving an insert on a first angular sector, and the opening is substantially circular and has a clearance to allow passage of the extension of the annular flange, the clearance extending radially outwardly of the opening on a second angular sector and being shaped so that its cooperation with the annular flange axially retains the rotor in the head of the stator; the predetermined angular position is an intermediate angular position disposed between a neutral end angular position and an active angular end position; and the opening is shaped so that its cooperation with the annular flange allows rotation of the rotor in a direction of rotation opposite to the predetermined direction of rotation to an active extremity angular position, such as the start position. According to a second aspect, the invention also relates to a steering lock for a motor vehicle, characterized in that it comprises at least one lock as defined above.
    [0003] Other features and advantages of the invention will appear on reading the following description of a preferred embodiment of the invention, given by way of non-limiting example and with reference to the appended drawings, in which: FIG. 1 is a perspective view of a motor vehicle steering column lock, FIG. 2 is an exploded view of the lock of the lock of FIG. 1, FIG. 3 illustrates a perspective view of the lock rotor of FIG. FIG. 2, FIG. 4 illustrates a perspective view of the stator head of FIG. 2, FIGS. 5 and 6 represent sectional views of the lock of FIG. 2 respectively when the rotor is in a so-called "retracted" position. and an "exit" position, FIG. 7 illustrates a perspective view of the lock of FIG. 2 with the rotor of the lock in the "out" position, FIGS. 8 and 9 represent sectional views of the lock of FIG. 2 respectively. When the latch is in the "Stop", "On" position, and FIG. 10 represents a view similar to FIG. 9, the driver pressing the rotor to move from the "On" position to the "Stop" position to be able to withdraw the key. In the various figures, the analogous elements are designated by identical references. In addition, the various elements are not necessarily represented on the scale in order to present a view making it easier to understand the invention. FIG. 1 illustrates a steering column antitheft device 2 with an insertable lock designed to be mounted in a motor vehicle in order to secure its steering.
    [0004] The lock 2 comprises an antitheft body 4 inside which a lock 6 is intended to be inserted and secured. As shown in the exploded view of FIG. 2, the latch 6 comprises a stator 8, a rotor 10, a cam 12 and a resilient element 14. The stator 8 comprises a stator head 16. The stator head 16 at the front, an opening 18 is formed in the rotor head to allow access to the rotor head. At the rear, the stator head 16 has a housing of suitable shape to receive the rotor 10, for example of generally cylindrical shape. The rotor 10 is rotatably mounted relative to the stator about an axis denoted I-I. The rotor is capable of being rotatable axially about this axis II by rotation of a key insert to control a locking means of the lock 2. The rotor 10 has a key inlet 20 provided to the front end also called the rotor head. It will be understood that, throughout the text, the term "rotor" designates very generally any subassembly comprising a rotor body through which radial slots 22 are provided, able to receive flakes which are mounted to move in translation. radial and which are coupled to return springs permanently causing them in protruding positions relative to the rotor body. The flakes allow the release of the rotor when a key insert corresponding to the coding formed by the disposition of the flakes is introduced into the rotor. The rotation of the key is likely to cause the rotation of the rotor 5 in a first neutral extreme angular position, said neutral position, as the "stop" position, two intermediate angular positions, said "On" and "Accessories" positions and a second extreme active angular position, opposed to the first neutral extreme angular position, called "Start" position. The positions "Neutral", "Intermediate" and "Start" follow one another when the rotor 10 is moved from the "Neutral" position to the "Start" position. After passing through the starting position, the rotor 10 is resiliently returned by a return spring to its intermediate position "on". The locking means comprises a bolt 24 movably mounted between a retracted position in which the bolt 24 is held at a distance from a steering column (not shown) and a projection position, as illustrated in FIG. which it blocks the steering column of the motor vehicle. For this, the cam 12 is intended to be integral in rotation with the rotor, so that the rotation of the rotor 10 allows to control the translation of the bolt 24.
    [0005] The bolt 24 is generally in the projecting position in the steering column when the rotor 10 is in the neutral position, the bolt 24 being kept retracted, in the retracted position, in the other angular positions of the rotor 10. The bolt 24 is urged in thrust in projecting position by a bolt spring. The elastic element 14 is arranged coaxially between the cam 12 and the rotor 10 to urge said rotor 10 in thrust. For example, the elastic element 14 is a compression spring. The rotor 10 is thus in sliding connection with the cam 12, that is to say that the rotor 10 is connected in rotation with the cam 12 but not in translation, the elastic element 14 pushing the rotor 10 in the unpressed position .
    [0006] In addition, the rotor 10 comprises an annular flange 26. According to the invention, the opening 18 is shaped so that its cooperation with the annular flange 26 blocks the rotation of the rotor 10 in a predetermined direction of rotation from a position predetermined angle and allows the rotation of the rotor 10 beyond the predetermined angular position by depressing the rotor beforehand. According to one embodiment of the invention, the predetermined angular position is an intermediate angular position, for example the "On" position, arranged between a neutral end angular position, "Stop" position and an active angular end position, "Starting" position. ".
    [0007] By this means, the key can not be extracted from the lock 6 by a simple withdrawal movement in the "Stop" position. It is necessary to press the key beforehand in the lock 6 to then be able to extract it. This prevents any untimely or malicious extraction of the key, especially because of the danger that the extraction of the key is when the vehicle is running.
    [0008] According to a preferred embodiment shown in FIGS. 3 and 4, the annular flange 26 comprises an extension 28 which extends axially towards the head of the rotor 10 over a first angular sector of angle θ. opening 18 is substantially circular in radius R1 and has a clearance 30 to allow passage of the extension 28 of the annular flange 26. The clearance 30 extends radially outwardly of the opening 18 on a second angular sector In other words, on the second angular sector of angle denoted 02, the assembly formed by the opening 18 and the clearance 30 is substantially circular in radius R2 strictly greater than the radius R 1. The angle θ2 is at least equal to the angle θ. The clearance 30 also comprises a radial abutment 32 shaped to block the rotation of the rotor 10, during the rotation of the rotor 10 in the counterclockwise direction from the position predetermined angle. In addition, the clearance 30 is shaped so that its cooperation with the annular flange 26 axially retains the rotor 10 in the head of the stator 16. For this purpose, the stator head 16 has an axial stop 34 located on the front side of the rotor. The axial stop 34 is shaped to axially retain the rotor 10 in the stator head 16 while permitting the depression of the rotor 10. In other words: when the extension 28 of the annular flange 26 is not opposite of the clearance 30, the rotor is retained in translation in a so-called "retracted" position as illustrated in FIG. 5, and when the extension 28 of the annular flange 26 is opposite the clearance 30, the rotor is pushed by the element elastic 14 and therefore translate along the axis II in a position called "output" as shown in Figures 6 and 7. According to another embodiment, the opening is further shaped so that its cooperation with the annular flange 26 allows rotation of the rotor in a direction of rotation opposite to the predetermined direction of rotation to an active end position, such as the "Start" position. Thus, according to the invention, the angle θ 2 is greater than the angle θ 1 allowing rotation of the rotor 10 in the clockwise direction between the "on" position and the "start" position, that is to say when the rotor 10 is in the "output" position. The clearance 30 further comprises an additional radial abutment 36 corresponding to the "Start" position shaped to block the rotation of the rotor 10 in the direction of rotation opposite to the predetermined direction of rotation, that is to say the direction beyond the "Start" position. An example of operation of the lock will now be described with reference to FIGS. 8 to 10. It is assumed with reference to FIG. 8 that the vehicle is at a standstill and that the driver is introducing the key (not shown) into the rotor 10. along axis II to start the vehicle. The lock 6 is then in the "stop" angular position indicated PS in FIG. 4. The rotor is in the "retracted" position.
    [0009] Then, the user begins turning the key in the clockwise direction, rotating the rotor 10 in the stator head 16. As long as the lock 6 has not reached the predetermined angular position, for example the intermediate position " On PIM, the rotor 10 remains in the "retracted" position. When the rotor 10 reaches the predetermined intermediate position, for example "on" PIM (FIG. 9), the rotor 10 translates into the "output" position under the action of the spring 14 along the arrow Fi (FIG. 9). The axial stop 34 holds the rotor 10 axially in the stator head 16 in this "output" position. As soon as the rotor 10 is in this "output" position, the extraction of the key is impossible.
    [0010] Rotation of the rotor 10 can be continued clockwise to the "Start" position. Between the predetermined angular position, here the intermediate position "On" and the angular position "Start", the rotor 10 remains in the "output" position under the action of the spring 14 and is retained in the stator head 16 by the axial abutment 34.
    [0011] The rotation of the rotor 10 in the clockwise direction is prohibited beyond the "Starting" position by the abutment of the extension 28 of the flange 26 against the radial abutment 36. After the engine has been started in the "Starting" position, the latch automatically returns to the "On" position, the rotor being always in the "Output" position during its rotation in the counter-clockwise direction. From the predetermined angular position, the "On" position in this example, when the driver turns the key in the opposite direction (direction of rotation -9- anti-clockwise), the rotation of the rotor 10 is prohibited by the abutment the extension 28 of the flange 26 against the radial stop 32. It is therefore not possible to rotate the rotor 10 from the intermediate position "Start" PIM to make it return to the "Stop" position and remove the key.
    [0012] In this stop position, the driver must then drive the rotor 10 into the stator head 16 (arrow F2 in FIG. 10), allowing the radial stop 32 to pass through the extension 28 of the collar 26. Before to reach the "Stop" position PS, the rotor 10 returns to the "retracted" initial position (FIG. 8) until the extension 28 of the flange 26 abuts against the axial abutment 34. Then the driver continues to turn the rotor 10 to reach the stop position in which the driver can then extract the key from the lock 6.
