Description

MOTOR VEHICLE DOOR LOCK

The invention relates to a door lock for a motor vehicle, in particular of the type comprising a rotary bolt with a fork and a rotary catch for retaining the bolt. It is known that a motor vehicle door is generally held in the closed position by a lock, the bolt and pawl of which are arranged parallel to the edge of the door, the keeper being integral with the bodywork amount which is in the immediate vicinity of the door edge. The lock housing has a notch for the passage of the keeper; the strike, when the door is closed, enters the bolt fork, which pivots in a position where it retains the strike and which is held in this position by the pawl. This well-known type of lock is always associated with a certain number of peripheral elements intended for controlling the lock, namely, on the one hand, control members for opening the door from the inside. or from the outside of the passenger compartment, on the other hand, locking and unlocking devices operating from inside or outside the passenger compartment, and finally safety devices, for example a locking device avoiding untimely opening of the lock by a child. The presence of all these peripheral elements unfortunately leads, for locks of this type, to a complicated shape and the movable parts of the lock are arranged around axes, which are parallel not only to the longitudinal axis of the vehicle, which is the case for the ratchet and the bolt, but also around axes parallel to the transverse axis and to the vertical axis of the vehicle. It therefore follows that the locks have a complicated shape and, since it is necessary to protect against burglary the peripheral elements controlling the lock, it is necessary to associate with the lock protective covers of tormented form, which are troublesome for mounting the lock in the door; these covers are moreover heavier and more expensive that they have a more tormented shape. But, in addition, locks of this type are extremely sensitive to decelerations

^" brutal in the longitudinal direction of the vehicle due to the existence of moving parts, whose axes are perpendicular to the longitudinal axis of the vehicle. It follows that these moving parts must be carefully balanced by weighing down some of their parts and subjecting them to springs, from which it follows an increase in the weight and price of the lock.

In other words, the locks of the state of the art have the disadvantage of comprising boxes having a square shape, the elements of which resist poor abrupt deceleration in the event of an accident, the square shape implying, as much for the structure of the component parts of the lock than for the casing, an increase in cost and weight. It is clear that it is highly desirable to produce a lock, the housing of which would have substantially the shape of a rectangular parallelepiped, this lock therefore having all of its elements in a plane perpendicular to the longitudinal axis of the vehicle.

The invention firstly aims to provide a lock in which all the axes of the moving parts are parallel to the same direction. Another object of the invention is to propose a lock, all of the constituent elements of which can be housed inside a substantially parallelepipedic housing, the large faces of which, when mounted in the door, are positioned parallel to the edge of the door. The invention also aims to provide a lock in which the functions of opening, unlocking and locking inside and outside are independent, the unlocking and locking can be performed mechanically or electrically. The present invention therefore relates to a motor vehicle door lock, said lock being associated with internal and external control members which comprise, on the one hand, at least one door opening element and, d on the other hand, at least one locking / unlocking element of the lock, said lock cooperating with two connecting devices (15, 16) associated, one with the internal control members, and the other with the control members exterior, each connecting device comprising a connecting element which can take at least two

^" positions, characterized in that each connecting element of the connecting devices (15, 16) is associated with a lever (12, 13) and a pivoting arm (11, 14), the two levers and the two pivoting arms being arranged parallel to the same face of the lock housing, so that the axes (9, 14a) of the lock are all perpendicular to said face of the housing.

Provision may be made for the pivoting of the pivoting arm associated with the external control members to cause the pivoting arm associated with the internal control members to pivot, so that the external unlocking causes the internal unlocking.

Advantageously, the connecting element of a connecting device can take a so-called middle position and a position called first extreme position, said middle position corresponding to the absence of action by the user on the control members mechanically connected to the lock and said first extreme position corresponding to the action of the user on a door opening element, each connecting element of said connecting devices (15, 16) cooperating, in the housing 1 of the lock with a lever (12, 13) suitable for causing the opening of the lock when the connecting element passes from its middle position to its first extreme position, each of these two levers (12, 13) being susceptible, on the one hand, when the lock is in the unlocked position, to pivot around an axis (10, 13d) under the action of a locking element, to escape the action of its associated connecting element when it comes in its first posit ion extreme, and secondly, when the lock is in the unlocked position, to perform the reverse pivot under the action of a unlocking element, the connecting element of at least one of the connecting devices ( 16) being capable, to ensure the mechanical unlocking control of the lock in the locked position, to take a third position, called the second extreme position, and cooperating with a pivoting arm (14), which is driven by said connecting element when this the latter passes from its middle position to its second extreme position and which, by rotation, returns the lever (12) associated with said connecting element to the angular position where it can cause the opening of the lock.

Can be provided that the pivoting arms associated with organs ^"inner command is electrically controlled to drive the pivoting of the lever associated with the inner control members in the direction of its setting blocking position. In addition, the interior and exterior locking / unlocking elements can be controlled electrically and / or mechanically.

In a preferred embodiment, the connecting element of a connecting device moves in translation and the levers associated with the internal and external control members are also capable of moving in translation under the action of their connecting element respective, each lever being subjected to a spring, which recalls it in the opposite direction to that corresponding to the action of the connecting element for opening the lock.

The lever associated with the external control members can advantageously be electrically rotated to bring it into its locking position. It is also possible to provide that the translation of the lever associated with the internal control members in the direction of opening the lock causes, if the lever associated with the external control members is in the locked position, the pivoting of said lever to bring it in the unlocked position.

Advantageously, the pivoting arm associated with the internal control members is capable of being rotated by the user by direct manual action on the end of its axis, which is accessible on the lock housing in the edge of the door. , to bring the lever associated with the external control members into its locked position; in this way, even in the event of a battery failure, it is possible to condemn the lock vis-à-vis the outside, unlocking intervening by the action of the user on the external unlocking element, which acts on the external control swivel arm.

As already proposed in French patent application 95-12133 filed by the applicant, it can advantageously be provided that the connection device associated with the internal or external control members is a cable with a curvilinear sheath, in particular, positioned in the shape of a U to inside the door, one end

^" of the sheath being fixed relative to the vehicle door, while the other is connected to a manual unlocking element when one exists, one end of the cable being connected to the element door opening while the other is the connecting element acting on the lock.

The lock housing according to the invention is covered with a protective cover forming a simple cover given the rectangular parallelepiped shape of the lock, a large face of which is positioned parallel to the door edge.

The lock according to the invention preferably comprises a rotary fork bolt and a bolt retaining pawl.

To better understand the object of the invention, we will now describe, by way of purely illustrative and non-limiting example, an embodiment shown in the accompanying drawing.

On this drawing :

Referring to the drawing, it can be seen that the whole of the lock housing according to the invention has been designated by 1. The housing 1 has a rectangular parallelepiped shape and it has on one of its large faces a notch 2 allowing the passage of a keeper 3, which is fixed on the bodywork amount associated with the door where the lock is to be placed. The lock comprises a bolt 4 in the form of a fork and a pawl 5 which cooperates with the bolt to lock the latter in the position where it retains the keeper by one of the branches of its fork. The lock moves to the closed position when the door is slammed and the strike repels the bolt. When you want to put the lock in the open position to be able to open the vehicle door, you must pull the pawl 5 to disengage it from its zone of contact with the bolt, this traction being effected by exerting a force on the pin 6 of the ratchet. The axes of the bolt and the pawl are perpendicular to the large faces of the housing 1, that is to say arranged

^" parallel to the longitudinal axis of the vehicle, when the door is closed; these axes have been designated respectively by 4a and 5a and have been shown diagrammatically by a dashed line with the same reference in FIG. 2. In the lock described by way of example, the exterior and interior locking functions are electrically fulfilled by means of two actuators 7, 8 which are electric motors supplied from the vehicle battery. The motors 7, 8 drive, via a gear train and an endless screw, a pivoting cleat respectively 7a, 8a whose pivot axis, respectively 9 and 10, cooperates, for the first , with an internal control arm 1 1 and, for the second, with an external control lever 12. Referring now more particularly to the figures

3 and 4, it can be seen that the lock according to the invention comprises a mechanism consisting, on the one hand, for the internal control, of a lever 13 and of a pivoting arm 11 and, on the other hand, for the control exterior, a lever 12 and a pivoting arm 14. These four parts are arranged parallel to each other in different planes relative to the large faces of the housing 1. The pivoting arm 14 is the one, the plane of which is located closest to pawl 5; in a first adjacent plane (away from the pawl 5), are the lever 12 and the pivoting arm 11; in a second plane adjacent to the first (away from the pawl 5), is the lever 13. The levers 12 and 13 have identical shapes; they comprise, at one end, a square tab 12a, 13a respectively and, at their other end, a recess 12b, 13b respectively, in the vicinity of which an oblong recess 12ç, 13ç respectively has been provided. One of the edges of the redent is perpendicular to the average longitudinal line of the lever and the other edge is oblique and makes an acute angle with said average line. In the housing 1, the two levers are positioned so that their brackets 12â, 13a are disposed above one another. In the oblong recesses 12c, 13ç_, axes 10 and 13g are arranged! respectively. The axis 13d is a cylindrical axis having only a function of stroke limiter for the translation of the lever 13; on the contrary, the axis 10 has a flat section and can cause the lever 12 to rotate under the action of the actuator 8; but it also allows

^" The translation of the lever 12 relative to the axis 10. The pivoting arm 14 can rotate about its axis 14a; the axes 4a, 5a, 9, 13d, 10 and 14a are parallel. The pivoting arm 14a a fork shape and, in the rest position of the lock which is shown in Figure 3, one of the branches 14b of the fork can cooperate with the edge of the lever 12 while the other branch 14c_ of the fork can come to cooperate with a stud l ia carried by the pivoting arm 11 on its face, which is opposite the pivoting arm 14.

The pivoting arm 1 1 has a groove 11b, which opens to the outside of the arm; the mean line of this groove l lh is first of all, from the outside, a straight segment, then a curvilinear segment, said curvilinear segment making the groove oblique towards the axis 9. In this groove l lh , is set up a stud 13e, which protrudes from the face of the lever 13 which is opposite the pivoting arm 11. The straight segment of the groove 1 lb allows translation of the lever 13 relative to the arm pivoting 11; the curvilinear segment of the groove 11 b allows, when the pivoting arm 11 is pivoted about the axis 9, to cause the lever 13 to pivot relative to the axis 13d. The levers 12 and 13 are each subjected to a return spring which tends to bring them back to a position where the axes 10 and 13d are respectively supported at the bottom of their associated oblong recess. The operation of the lock according to the invention is carried out by means of two connecting devices each consisting of a sheathed cable. One of the devices 15 corresponds to the interior control while the other device 16 corresponds to the exterior control. Each sheath cable is formed in a U and corresponds to the device described in French patent application 95-12 133. The sheath of the cable 16 is connected by one of its ends to the housing 1 of the lock and, by its other end, to the thresher of a door barrel; the sheath of the cable 15 is linked by one of its ends to the housing 1 of the lock and by its other end to the frame of the door. The cable of these connecting devices is integral, at one of its ends, with a door opening element constituted, for example, by a door handle, and, at its opposite end, said cable cooperates with the one of the steps 12b, 13 & of the two levers 12 and 13 respectively. The

^" Figure 6 shows in detail the cooperation of the two cables with the levers 12 and 13. To the right of the flat axis 10 is a plate 17, which is clearly visible in FIGS. 10 and 11. The plate 17 is arranged above the plane of the lever 12, at the level of the plane of the lever 13, and, when the lever 13 is driven in translation parallel to the long side of the housing 1, the oblique edge of the redent 13b comes into contact with the edge of the plate 17 and causes the lever 12 to rotate if this lever was in an oblique position relative to the lever 13, so as to cause it to be parallel to the lever 13.

The operation of the mechanism, which has just been described, will be detailed below.

Referring to FIGS. 7, it can be seen that FIG. 7A represents the two levers 12 and 13 and the two pivoting arms 13 and 14 in the position which corresponds to a non-locked lock, door closed. If you want to open the door, you must bring the pin 6 of the pawl down in Figures 7. In Figure 7B, there is shown the movement of the lever 12 by means of the connecting element of the connecting device 16, which corresponds to an opening by external control, under the action of the door handle. When the door handle is released, the lever 12 returns to the position it had in FIG. 7A due to the action of its return spring, but the pawl pin 6 does not go back into the position it had initially, since the pawl 5 comes to bear on the side edge of the bolt 4. If the door is slammed, the pawl pin 6 returns to the position it had in Figure 7 A. Figures 7C and 7D represent the operation of the mechanical system for control by the interior door handle. In this case, the connecting element 15 acts on the redent 13b of the lever 13 and drives the lever 13 downwards in FIGS. 7. The angled tab of the lever 13 drives the pin 6 downwards, which causes opening the lock. The stud 13g slides in the rectilinear part of the groove l li> without any modification of the position of the pivoting arm 11. When the action on the door handle is released, the connection element of the connection device 15 resumes the initial position, which it had in FIG. 7C; But

^" the pawl pin 6 remains substantially in the low position, as for opening under an external control. The lever 13 is returned by its return spring to the initial position which it occupied before the opening command and which is shown in Figure 7C. As before, if the door is closed by slamming it, the pin 6 rises to reach its initial position below the brackets 12a, 13a of the two levers. Referring now to FIGS. 8, it can be seen that FIG. 8A represents the position of the lever 12 and of the pivoting arm 14, when the external opening control has been electrically locked. FIG. 8B represents the unlocking position, which corresponds to that of FIGS. 7: the lever 12 has its mean line parallel to the longest sides of the lock.

If the axis 10 is controlled by the actuator 8, the lever 12 can be brought into the position shown in FIG. 8 A, where it makes an acute angle with its previous position. In this position, the movement of the connecting element 16 takes place along the oblique edge, which delimits the redent 12b, so that the movement of the connecting element 16 does not cause any change in the position of the lever 12 , which corresponds to an impossibility of maneuvering the pawl 6 by the lever 12 and, consequently, to an external locking of the lock. The unlocking is obtained by rotating the axis 10 in the opposite direction, to bring the lever 12 to the position shown in FIG. 8B.

In FIGS. 9, the kinematics are shown in the case of an interior locking or unlocking. This case corresponds to security to prevent the door from being opened by children inside the vehicle and also corresponds to what is called a "super-conviction", namely the impossibility, in the event of a break-in by glass break, to open the door from inside the vehicle. The unlocking position is shown in Figure 9A and, in this case, we find the lever 13 and the pivoting arm 11 in the position they occupied in Figure 7A. To carry out the internal locking, the pivoting arm 11 is pivoted by controlling the rotation of its axis 9 by means of the actuator 7; during this pivoting, the stud 13e of the lever 13 slides in the part

- Curvilinear groove 11b, which causes the pivoting of the lever 13 in a position symmetrical to that taken by the lever 12 to ensure the external locking. Under these conditions, the edge oblique of the redent 13b comes along the stroke of the connecting element 15, when the latter moves under the action of an operation of the interior door handle. As a result, the connecting element 15 can no longer impart any movement to the lever 13, which corresponds to the interior locking.

As has been seen so far, the exterior unlocking is carried out electrically. However, the vehicle battery may be faulty, in which case it is necessary to provide an external unlocking by manual action on the barrel with which at least one of the vehicle locks is associated. In this case, the operation of the barrel by means of the user's key causes, as explained in French patent application 95-12133, a displacement of the connection element of the connection device 16 from its middle position, which corresponds to a rest position and is shown in FIG. 12A, towards its second extreme position, which corresponds to that which is opposite to the extreme position generating the opening of the lock. In this movement, said connecting element maneuvers the pivoting arm 14, so that it pivots about its axis 14a. Since the lock is assumed to be locked on the outside, the lever 12 is in an oblique position corresponding to that shown in FIG. 8A. When the pivoting arm 14 rotates under the action of the connecting element of the connecting device 16, the branch 14b comes to rest against the lever 12, which causes the pivoting of the lever 12 to bring it into a position where its mean line is parallel to the longest sides of the housing 1; in this position, the square tab 12a comes in line with the pawl pin 6. If the barrel is brought back to the rest state, said connecting element returns to its middle position, which is shown in FIG. 12C ; and, in this case, a subsequent operation of the exterior door handle causes the translation of the lever 12, and, consequently, the opening of the door. The manual back-up function is thus ensured so that unlocking can take place from the outside, even in the event of a battery failure.

It may happen that the two levers 12 and 13 are in the locking position and that the external unlocking is ensured as previously indicated. In this case, if the user entered his car and closed the door, he could not open from the inside, except to electrically unlock the interior, which would not be possible in the event of a battery failure. In the lock according to the invention, provision has been made to bring the lever 13 into its unlocking position at the same time as, by the emergency function, the lever 12 is brought into its unlocking position. To do this, the end of the branch 14c of the pivoting arm 14 comes to bear against the stud l ia of the pivoting arm 11, so that, when the pivoting arm 14 pivots to ensure the external emergency unlocking, it drives the rotation of the pivoting arm 11 to bring it from the position which corresponds to FIG. 9B to the position which corresponds to FIG. 9A, position in which the lever 13 has its mean line parallel to the longest sides of the housing 1. The unlocking outside in the emergency function thus automatically leads to internal unlocking.

The lock according to the invention also makes it possible to achieve another security. Indeed, if the lock is in the exterior locking position and in the interior unlocking position, it would be possible for a user inside the passenger compartment to open the door by the interior door handle; after which, if carelessly slams the vehicle door leaving the key inside the passenger compartment, the user is unable to open the door lock from the outside. To avoid this drawback, the plate 17 has been associated with the axis 10, which is located at the level of the lever 13. If the user in the above-defined lock position, which corresponds to FIG. 10A, operates the handle door interior, it drives the translation of the lever 13, as shown in FIG. 10B; towards the end of the translational travel of the lever 13, the oblique edge of the redent 13b comes into contact with the plate 17, which causes the rotation of the lever 12 around its axis 10 until this lever comes into position unlocking, as shown in Figure 10C. In this case, when the user releases the interior opening handle, the lever 13 returns to its high position under the effect of its return spring and if the user slams the door, the two levers are found in the position of unlocking, so O 97/36074 PC17FR97 / 00534

13

that the user can return to his vehicle again, this position being shown in FIG. 10D.

Finally, the lock according to the invention makes it possible to carry out a final security function in the event of a battery failure. If it is assumed that the lever 12 is in the unlocked position, the user can no longer condemn the lock from the outside. However, if he wants to get help, it is desirable that he can close his vehicle during his absence. In this case, the user opens his door to gain access to the door edge and to the large face of the housing, which is flush with the door edge. On this large face, the axis 9 of the pivoting arm 11 is accessible from its end. There is provided on the end of said axis 9 a slot for introducing a tool such as a screwdriver, a key or a coin, and the axis 9 is rotated so as to drive the pivoting arm 1 1 in the opposite direction to that in which it pivots to ensure the interior locking. In this case, the end of the pivoting arm 11 comes into contact with the end of the square tab 12â of the lever 12 and makes the lever 12 pivot to its locked position. When the rotation action printed by the user on the axis 9 ceases, the pivoting arm 11 returns to its initial position under the effect of a return spring. If the user then slams his door, the lock is in the external locking position and the user can again enter his vehicle by acting with his key on the barrel, as indicated above when the description has been given. manual emergency unlocking function.
