Description
"A Motor Vehicle Door Lock" 2304796 This invention relates to a motor
vehicle door lock having a rotary latch, a pawl and a release lever, having an operating lever system which acts on the release lever and which comprises an interior operating lever, having a locking lever system which comprises a locking central lever with an interior locking lever connected to the locking central lever, and having a central locking drive and a central locking element connected to the locking central lever, wherein the central locking drive is designed as a reversible electric motor drive which comprises an output element having at least one eccentric control pin, wherein the control pin can be controlled to execute anti-clockwise and clockwise control movements on an arc of rotation and can thereby be controlled so as to move the central locking element into "unlocked" and "locked" operating positions, wherein in its "locked" operating position the control pin is free from the central locking element and permits manual operation of the central locking element between the "locked" and "unlocked" operating positions, wherein the locking central lever is connected to the operating lever system via a coupling lever, and wherein the interior operating lever can be operated with idle travel in the "locked" operating position of the coupling lever. As a rule, at least the rotary latch, the pawl and the release lever are disposed on a lock plate. In this respect, the term "lock.plate" also comprises partially open or closed casings.
2 The electric motor of the central locking drive may be connected to the output element directly or via a gear system. In the latter case, examples of suitable gear systems include a spur gear, a worm gear pair or a planetary or epicyclic gear. It should be understood that in motor vehicle door locks such as this the facility of manual locking or unlocking is generally provided, at least from the interior space of the motor vehicle. The expression "manual locking or unlocking" means that the motor vehicle door lock can be operated and unlocked or locked, by means of an interior handle which can be moved into "locked",, "unlocked" and "actuated" operating positions, for example, even if the power supply to the central locking drive fails. Motor vehicle doors locks comprising central locking drives are usually operated is electrically, or locked and unlocked, from outside the motor vehicle. This can be effected with a mechanical or with an electronic key. In this connection, the expression "electronic key" also covers a remote operating device which operates via electromagnetic waves (IR or HF). In particular, the motor vehicle door lock can be integrated within a control installation for a motor vehicle, by means of which other components of the motor vehicle, such as the roof lock, bonnet lock, glove compartment lock, window lifters, theft alarm, etc., can be controlled in addition to the motor vehicle door locks.
A motor vehicle door lock of the construction cited at the outset is known from the literature reference EP 0 267 423 B1, for example. In the motor vehicle door lock which is known in this respect, no theft-protection function is provided. The expression "theft-protection function" means a particular operating position of the motor vehicle door lock in which the locked motor vehicle door lock cannot be unlocked from the interior space of the motor vehicle. The object of the theft-protection function is to prevent an unauthorised person from being able to open the motor vehicle door lock after a manipulative intervention through a window section or door gap. In the known motor vehicle door lock the protection from theft is consequently unsatisfactory.
A basic object of the present invention is to equip a motor vehicle door lock of the construction cited at the outset with a theft-protection function.
According to the present invention there is provided a motor vehicle door lock having a rotary latch, a pawl and a release lever, having an operating lever system which acts on the release lever and which comprises an interior operating lever, having a locking lever system which comprises a locking central lever with an interior locking lever connected to the locking central lever, and having a central locking drive and having a central locking element connected to the locking central lever, wherein the central locking drive is designed as a reversible electric motor drive which comprises an output element having at least one eccentric control pin, wherein the control pin can be controlled to execute anti- clockwise and clockwise control movements on an arc of rotation and can thereby be controlled so as to move the central locking element into "unlocked" and "locked" operating positions, 1 - 4 wherein in its "locked" operating position the control pin is free from the central locking element and permits manual operation of the central locking element between the "locked" and "unlocked" operating positions, wherein the locking central lever is connected to the operating lever system via a coupling lever, and wherein the interior operating lever can be operated with idle travel in the "locked" operating position of the coupling lever, wherein the locking central lever and the coupling lever are non-positively connected to each other by means of a coupling spring with respect to a movement from the "locked" operating position into the Ifunlocked" operating position, that the coupling lever comprises a theft-protection element, and that the control pin can be moved into a "theft-protected" operating position in is which the control pin locks the coupling lever in its "locked" operating position via the theft-protection element.
Due to the coupling lever being non-positively connected to the locking central lever, the coupling lever can be held in its "locked" operating position by means of the theft-protection element when the interior locking lever and the locking central lever, which is usually positively connected to the interior locking lever, swivel into their l#unlocked" operating position. one particular advantage of the invention is that the theft-protection function which is provided in this respect can be activated by means of the control pin which is present anyway.
The theft-protection element is advantageously disposed on a theftprotection limb of the coupling lever and the theft-protection element advantageously has a locking edge which engages behind the control pin in the "thef t-protected" operating position of the latter. In this respect, the theftprotection element can be articulated on the theft-protection limb and can be swivelled between a "normal operation" operating position and an "emergency unlocking" operating position, wherein the theft-protection element is springloaded towards the "normal operation" and towards the '@emergency unlocking" operating positions by means of a bistable rocker spring disposed between the theft-protection element and the coupling lever. It is also advantageous if the theft-protection element comprises a control edge which is associated with a control arm of an exterior locking lever connected to the locking central lever, wherein the is arrangements of the control edge and of the control arm are effected so that when the exterior locking lever swivels into its "unlocked" operating position the theft-protection element can swivel in relation to the coupling lever into its f#emergency unlocking" operating position against the spring force of the rocker spring. This form of construction ensures that it is possible to unlock the motor vehicle door lock via the external locking lever even if the control pin is jammed in its "theft-protected" operating position due to a malfunction. The bistable rocker spring is particularly important in this respect. The arrangements of the aforementioned elements can firstly be effected so that in the course of swivelling the exterior locking lever into its "unlocked" operating position the theft- protection element is 6 swivelled into its "emergency unlocking" operating position and remains in this operating position even after a subsequent locking operation via the exterior locking lever. The arrangements can secondly be effected so that in the course of moving the exterior locking lever into the Ifunlocked" operating position the theft-protection element is first swivelled into the "emergency unlocking" operating position and in the course of the further movement of the exterior locking lever into its "unlocked" operating position it returns to the "normal operation" operating position again. The first- mentioned alternative is preferred, and has the advantage that if there is a malfunction of the central locking drive a person cannot inadvertently be locked in the motor vehicle. The second alternative mentioned has the advantage that the theftprotection function also remains active and ensures protection from theft in this respect when there is manual operation via the exterior locking lever.
In association with a control installation, it is advantageous if a switching lever is mounted on the theft- protection limb coaxially with the theft-protection element, if the switching lever comprises an operating element and a switching element, and if in the "theft-protected" operating position of the control pin the switching lever can be swivelled by the latter via the operating element, against the spring force of a biassing spring, so as to operate an electrical switch by means of the switching element.
Further advantageous forms of construction are given in claims 5 to 14.
The invention is described in more detail below with reference to the drawings, which merely illustrate an example of an embodiment, and where:
Figure 1 is a general view of a motor vehicle door lock according to the invention, in the "unlocked" operating position; Figure 2 illustrates a portion of the lock of Figure 1, in the "locked" operating position; Figure 3 illustrates the lock of Figure 2, in the "theft-protected" operating position; and Figure 4 illustrates the lock of Figure 2, in the "theft-protected" operating position and with the interior locking lever actuated.
It can be seen from Figure 1 that the motor vehicle door lock is equipped with a rotary latch 1, a pawl 2 and a release lever 3. An operating lever system, which comprises an interior operating lever 4, acts on the release lever 3. A locking lever system is also provided, which comprises a locking central lever 5 with an interior locking lever 6 which is positively connected to the locking central lever 5. A central locking drive is provided, which is designed as a reversible electric motor drive, and which comprises an output element having at least one eccentric control pin 8. A central locking element 7 is connected to the locking central lever 5. The control pin 8 can be controlled to execute anticlockwise and clockwise control movements on an arc of rotation 9 and can thereby be controlled so as to move the central locking element 7 into "unlocked" and "locked" operating positions.
The central locking element 7 comprises a forked receiver 25 having control surfaces 26 which are disposed at the sides of the forked receiver 25 and which are associated with the control pin 8. Part of the arc of rotation 9 of the control pin 8 is situated outside the forked receiver 25. A stop face 33 for the control pin 8 is provided on one side near the forked receiver 25. The forked receiver 25 is open inwards in a radial direction with respect to the swivelling axis 24 of the central locking element 7. The control movements of the control pin 8 cover an angular range of 360', wherein in its inoperative position the control pin 8 is situated outside the forked receiver 25, as can be seen from Figures 1 and 2. The locking central lever 5 and the central locking element 7 are both disposed so that they can swivel about the swivelling axis 24, as is the exterior locking lever 18. The locking central lever 5 is connected to the operating lever system via a coupling lever 10, wherein the interior operating lever 4 can be operated with idle travel in the "locked" operating position of the coupling lever 10. The coupling lever 10 is likewise mounted on the swivelling axis 24. The idle travel operation of the interior locking lever 4 and of an exterior locking lever 27 which is additionally provided is achieved in that the release lever 3 is articulated on the coupling lever 10, that the exterior operating lever 27 comprises a substantially L-shaped aperture 28 and the interior operating lever 4 comprises a slot 29 running substantially in the longitudinal direction, that the release lever 3 comprises a guide pin 30 which passes both through the L-shaped aperture t 28 and through the slot 29, and that the release lever 3 has a control edge 31 for releasing the pawl 2, wherein in the 'Iunlocked" operating position of the coupling lever 10 the control edge 31 is actively connected to a release pin 32 of the pawl 2 and wherein in the "locked" operating position of the coupling lever 10 the control edge 31 is free from the release pin 32 of the pawl 2 and the interior operating lever 4 and the exterior operating lever 27 can thereby be operated with idle travel. It can also be seen from Figure 1 that the locking central lever 5 and the central locking element 7 are connected to each other via an emergency unlocking connecting element 43 which operates with a non-positive connection. In this respect, the emergency unlocking connecting element 43 is constructed as a non-positive latching connection, wherein the connection between the locking central lever 5 and the central locking element 7 is separable only in the direction of the efunlocked" operating position of the locking central lever 5.
According to the invention, the locking central lever 5.,and the coupling lever 10 are non-positively connected to each other by means of a coupling spring 11 with respect to a movement from the "locked" operating position into the counlocked" operating position. The coupling lever 10 comprises a theft-protection element 12. In detail, the theft-protection element 12 is disposed on a theft- protection limb 13 of the coupling lever 10 and has a locking edge 14 which engages behind the control pin 8 in the "theft-protected" operating position of the latter. The theft-protection element. 12 is articulated on the theft-protection limb 13 and can be R swivelled between a "normal operation" operating position and an "emergency unlocking" operating position. The theft protection element 12 is spring-loaded into the two said operating positions by means of a bistable rocker spring 15 disposed between the theft-protection element 12 and the coupling lever 10. The theft-protection element 12 also comprises an edge portion 40 which engages in a positive locking recess 41 of the coupling lever 10 with positive fit but with sufficient play for the swivelling movement between the two operating positions of the theft-protection element 12. In addition, the theft-protection element 12 comprises a of the of the the control edge 16 which is associated with a control arm 17 the exterior locking lever 18 which is connected to locking central lever 5. In this respect, the arrangements is the control edge 16 and of the control arm 17, and of connection between the exterior locking lever 18 and locking central lever 5, are effected so that when the exterior locking lever 18 swivels into its "unlocked" operating position the theft-protection element 12 can swivel in relation to the coupling lever 10 into its "emergency unlocking" operating position against the spring force of the rocker spring 15. The connection between the exterior locking lever 18 and the locking central lever 5 is arranged in the usual manner, as illustrated in Figure 1, and ensures a neutral central position of the exterior locking lever 18.
The kinematic relationships become clear from a comparative examination of Figures 1 to 4. It can be seen from Figure 2 that in its 'locked " operating position the control pin 8 is free from the central locking element 7 and permits manual operation of the central locking element 7 between the "locked" and "unlocked" operating positions. In this connection, manual operation means operation via the exterior locking lever 18 or via the interior locking lever 6. It can be seen from Figure 3 that the control pin 8 can be moved into a "theft-protected" operating position in which the control pin 8 locks the coupling lever 10 in its "locked" operating position via the theft-protection element 12. in this position the control pin 8 has impinged against the stop face 33. It can be seen from a comparative examination of Figures 2 and 3 that the movement of the control pin 8 from its inoperative position into its "theft- protected" operating position covers an angular range of about 45'. it can be seen from Figure 4 that when the theft-protection function is activated a manual operation of the interior locking lever 6 merely results in an extension of the coupling spring 11, but does not result in the unlocking of the motor vehicle door lock.
Finally, it can be seen from a comparative examination of Figures 1 to 4 that a switching lever 19 is mounted on the theft-protection limb 13 coaxially with the theft-protection element 12, which switching lever comprises an operating element 20 and a switching element 21. In the "theft-protected" operating position of the control pin 8 the switching lever 19 can be swivelled by the latter via the operating element 20, against the spring force of a biassing spring 22, so as to operate an electrical switch 23 by means of the switching element 21. The spring force of the biassing spring 22 biasses the switching lever 19 towards the operating position illustrated in Figure 2.
A feature which is not shown in the Figures is that in this embodiment an interior handle is provided which can be moved into the "locked", "unlocked" and "actuated" operating positions. In this respect the interior handle performs a dual function, namely a locking and unlocking function and also that of the actuation of the motor vehicle door lock. For this purpose, the interior handle is connected to a transmission lever 42 as indicated in Figure 1 and to the interior locking lever 6 via a single Bowden cable having a Bowden cable core and a Bowden cable sheath. The Bowden cable sheath is fitted fixed to the motor vehicle door lock and the Bowden cable core is fixed to the transmission lever 42. The transmission lever 42 and the interior locking lever 6 are disposed so that they can swivel about fixed swivelling axes which are parallel to each other and perpendicular to the swivelling axis 24. The transmission lever has a coupling limb which engages in a coupling recess 6, which comprises a leaf spring on one side, of the interior locking lever 6. The leaf spring is disposed and designed so that the engagement of the coupling limb in the coupling recess is positive and practically free from play between the "locked" and "unlocked" operating positions of the transmission lever 42 and of the interior locking lever 6.
When the transmission lever 42 swivels from its "unlocked" operating position towards its "actuated" operating position, the coupling limb emerges from the coupling recess and runs along a sliding surface of the leaf spring.
