Definitions

  • the present invention relates to a mechanism for disengaging the manual locking member associated with a motor vehicle door lock; it also relates to a door lock for a motor vehicle comprising such a mechanism.
  • the manual locking member is disposed on the inside of the vehicle door and is generally called a "floppye pull tab".
  • a "floppye pull tab” we know that it is very desirable to be able to disengage such a locking member by carrying out what is called a "super-locking" so that the breaking of a window of the vehicle does not allow the author of the 'break-in, by acting directly on said locking member, to unlock the door and thus completely normalize access to the vehicle.
  • the keeper generally consists of an axis carried by the vehicle body and the bolt of the lock has the shape of a fork; this bolt is retained in the closed position by a pawl, the rotary operation of which enables the opening of the lock to be controlled.
  • a pawl the rotary operation of which enables the opening of the lock to be controlled.
  • vehicle door locks are generally equipped with manual locking members, called “floppye pulls", by means of which one comes manually, from inside the vehicle, to put the lock in the locked or unlocked position. If a vehicle is closed and locked, it is obviously possible, by breaking the door window, to act on the frieze zipper to unlock the lock; it has therefore been imagined to electrically control an inhibition of the action of the frieze zipper on the lock so that, in such a case, the perpetrator, by acting on the frieze zipper, cannot unlock the lock.
  • the object of the invention is to propose an embodiment, which is both particularly reliable and more economical than the prior devices.
  • the subject of the invention is a mechanism for disengaging the manual locking member associated with a door lock of a motor vehicle and arranged on the interior face of said door, said lock being able to take either a "locked" configuration where the lock can be operated from the inside and operation from the outside is possible only by electrical control or by acting on the key associated with the safety barrel of the lock, or a "super-condemned” configuration in which operation from the outside is possible only by electric control or by acting on the key associated with the safety cylinder of the lock and operation from the inside is impossible, ie a "unlocked” configuration in which the lock can be operated without restrictions both from the outside and from the inside of the vehicle, the transition from the "locked” configuration to the "unlocked” configuration and vice versa, carried out by rotation of a plate around a fixed axis of the lock, said plate being controlled by at least said manual locking member and a manual operating member separate from the said manual locking member, said manual locking member being able to assume only two positions, one in which it places the plate in the un
  • the plate is secured to a means which controls it electrically;
  • the manual operating member of the plate is the safety barrel of the lock;
  • the sliding assembly has a rectangular shape and moves in translation between two parallel extensions of the plate;
  • the sliding equipment window consists of two contiguous rectangular zones having substantially the same width, the short sides of these rectangles being substantially parallel to the extension of the plate;
  • the groove-slide comprises a rectilinear border parallel to the lengths of the two window zones and a circular border centered on the pivot axis of the plate;
  • the end of the pusher is substantially circular and has a diameter substantially equal to the minimum distance between the two edges of the groove-slide.
  • the means which provides the electrical control of the plate is a pivoting lever and that the pusher is secured to a pivoting arm, the aforementioned lever and arm being controlled by the same device.
  • This single control device for the pivoting arm and lever can advantageously be a device comprising a screw / nut system, the screw of which can be driven in both directions of rotation by an electric motor and the nut of which controls the pivoting of said lever by simple pressing against a drive zone of said lever, this device further comprising a fixed guide, in which a first orifice is formed, the closed outline of which constitutes a first cam profile, the nut of the screw / nut comprising, on one side of a diametrical plane, a driver which penetrates into the first orifice and cooperates with its cam profile and, on the other side of said diametral plane, two teeth substantially symmetrical with respect to an axis perpendicular to said axis diametral plane, each of the teeth being able to come to bear against one
  • the first cam profile is arranged substantially in a plane parallel to the axis of the screw;
  • the nut driver is a cylindrical nipple; at least one of the nut stop positions is determined by a micro-switch inserted into the electrical supply to the motor and controlled, directly or not, by the position of the nut.
  • a control device as defined above makes it possible to electrically lock and unlock a lock. If one wishes, moreover, to ensure a super-locking, it will be explained in the subsequent description, that it suffices, after having ordered the locking of the lock, to ensure the rotation of a pivoting arm and its maintenance in position, so that this simple rotation makes it possible to obtain the inhibition of an unlocking action carried out from the manual locking member known as a "floppye pull tab". Provision has therefore been made to provide this additional function with the control device defined above.
  • the device according to the invention further comprises a slide capable of moving in translation relative to the guide parallel to the axis of the screw, a second orifice being formed in said slide and defining by its closed contour a second cam profile, the nut driver also entering the second orifice and cooperating with the second cam profile, this second orifice comprising a substantially rectilinear groove at each of the grooves in the first orifice, the two grooves of the second orifice being, as for the first orifice, connected to each other by oblique ramps substantially parallel to those of the first orifice and spaced from one another by the same distance, said slide cooperating, at one end called " active "of its stroke, with a pivoting arm to constitute a wedge for said arm, that of the ramps of the slide which is on the opposite side at said active end comprising, in its zone of connection with that of the grooves of the second orifice where the driver is located for said active end of travel, a bearing support allowing the coach to ensure the translation of the
  • the lengths of the grooves of the first and second orifices located on the side of the inactive end of the travel of the slide are close; at the inactive end of its travel, the slide cooperates with a micro-contact inserted on the electrical supply of the motor; the slide comprises a brake cooperating with the frame to stop its translation quickly after the power supply to the engine is cut off.
  • the present invention also relates to a lock comprising a declutching mechanism such as that which has been defined above.
  • the lock is contained in a housing 1, the mean plane of which is arranged substantially parallel to the plane of the door on which the lock is fixed.
  • the housing 1, parallelepipedal consists of a front face 2, a rear face 3 substantially parallel to the front face 2, a right side face 4, a left side face substantially parallel to the right side face 4, and an upper face 6.
  • the section plane II is a vertical plane. To simplify the description, it will be assumed that the lock described is housed in a vertical housing 1, the face 6 of which is the upper face.
  • the lock according to the invention comprises an electrical control device consisting of an electric motor 7 provided with a pinion 8, which meshes on a toothed wheel 9 to constitute a reduction gear.
  • the axis B of the toothed wheel 9 is a screw 10 provided with a nut 11.
