Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of a catch and pawl, and with a locking element for a locking lever, the locking element preventing the locking lever from assuming its locking position when the locking mechanism is open. - As a rule, the locking element ensures that the locking lever remains in its unlocked position when the catch is open or open.
• the overall aim of this is to ensure that when the door is open and consequently the catch is open, the locking lever in question cannot assume its locking position. Because that could lead to the catch being closed. This in turn would have the consequence that the manually closed motor vehicle door, for example, strikes the obligatory locking bolt because the catch is no longer open.
• the previous embodiments cannot convince in all points. Because they fall back on mostly complex constructions. The invention seeks to remedy this overall.
• the invention is based on the technical problem of further developing a motor vehicle door lock of the configuration described at the outset in such a way that the locking lever is prevented in a simple manner from assuming its locking position.
• the invention proposes in a generic motor vehicle door lock that the locking element is designed as a locking lock controlled by the rotary latch which engages in a recess of the locking lever to block it when the locking lever is in the unlocking position.
• the locking lock according to the invention or the locking element thus actively moves into the relevant recess in the locking lever.
• a mutual striking and blocking the locking lock and the locking lever does not take place. This ensures under all circumstances that the locking lever maintains its unlocking position, as long as the locking lock or the locking element engages in the relevant recess of the locking lever to block it. Only when the locking lock leaves the relevant recess the locking lever is able, for example, to pass into the locking position.
• the locking lock is an essentially linearly movable push lever, which may be connected to an intermediate element acted upon by the rotary latch.
• the linearly movable thrust lever and the intermediate element which is generally designed as an intermediate lever rotatable about an axis, form a crank mechanism.
• the locking lock usually has a front nose which engages in the recess.
• it may have a stop on the front to limit its path, which has its effect when the nose is retracted. This means that the abovementioned stop ensures that the blocking movement of the push lever or the locking lock is limited, namely when the stop comes into contact with the locking lever with the nose inserted into the recess.
• the locking lock is usually guided on an insert or inlet insert.
• This inlet insert is in a housing or the lock case of the motor vehicle door Finally used and ensures the reliable guidance of the locking bolt on its way towards the rotary latch and away from it.
• the inlet insert may be designed as a plastic insert open in the direction of the rotary latch, which has a guide surface in the area of the locking lock.
• the locking lock also has a recess for a bearing journal of the intermediate element. Both the stop and the recess define and limit the respective end positions of the locking lock. This is because the locking lock can be moved back and forth between the retracted end position, which releases the locking lever, and the advanced position, which blocks the locking lever.
• the recess defines the retracted position that releases the locking lever, while the stop corresponds to the advanced position of the locking lock that blocks the locking lever.
• a motor vehicle door lock which has a locking element or a locking lock which holds the locking lever and subsequently the entire locking lever mechanism functionally reliably in the unlocking position, provided the catch is in its open position. Only when the rotary latch is closed is the locking lever released and can consequently take its "locked” position.
• Fig. 3 shows the motor vehicle door lock according to the
• a motor vehicle door lock which in its basic structure has a locking mechanism 1, 2 consisting of a rotary latch 1 and a pawl 2.
• the locking mechanism 1, 2 interacts with a locking bolt 3, which is only indicated in FIG. 1, in the usual manner.
• a sensor 4 is provided which is designed as a microswitch 4 within the scope of the exemplary embodiment.
• the intermediate element 5 which transmits the movements of the rotary latch 1 to the sensor 4.
• the intermediate element 5 is designed as an intermediate lever 5 with an essentially circular to oval overall design. in principle can of course be realized any intermediate elements 5 that are able to transmit the rotary movements of the rotary latch 1 to the sensor or microswitch 4. It is conceivable here to work with, for example, adjusting rods, toothed wheels, friction wheels, Bowden cables, etc. The least constructive effort, however, is represented by the intermediate lever 5 according to the exemplary embodiment.
• the intermediate element or the intermediate lever 5 is rotatably mounted about an axis 6.
• the rotary latch 1 has an axis 7, which is arranged substantially vertically in comparison. This angular arrangement of the two axes 6, 7 means that the intermediate element or the intermediate lever 5 is only taken along by the rotary latch 1 within a limited angle of rotation around the sensor or trigger microswitch 4.
• the described entrainment takes place when the rotary latch 1 leaves the main rest position shown in FIGS. 1 and 2.
• the pawl 2 may be lifted (mechanically or by motor), so that the catch 1 is one in FIGS. 1 and 2.
• this process ensures that the sensor or microswitch 4 is not triggered.
• the sensor or microswitch 4 can be arranged at practically any point within a lock housing or lock case 12. In the present case, its placement on an L-leg of the lock case or lock housing 12 has proven to be favorable. The rotary latch 1 therefore no longer specifies the position of the sensor 4.
• the intermediate element or the intermediate lever 5 is advantageously mounted on an insert 13 for the lock housing or the lock case 12. This is shown in particular in FIG. 3, where this insert 13 is shown.
• the insert 13 is an inlet insert 13, that is to say an insert which defines the inlet mouth 11 for the locking bolt 3.
• the insert or inlet insert 13 is an injection molded plastic part with an integrated damper element 14 for the locking bolt 3 and the rotary latch 1.
• This insert or inlet insert 13 has a fastening plate 15 with an extension, which receives a pin as axis 6, on which the intermediate lever 5 is in turn attached.
• the insert 13 and the intermediate lever 5 form a structural unit which can be connected as a whole to the lock housing or lock case 12, for example by latching, riveting, screwing, gluing etc.
• the intermediate element or the intermediate lever 5 may also be designed as a plastic injection molded part.
• a reinforcement plate IG which is also shown in FIG. 3, ensures, among other things, that the rotary latch 1 is held properly.
• the locking element or the thrust lever 17 together with the intermediate element or the intermediate lever 5 forms a crank mechanism, which is braked in its movement by a stop 21 on the front. This applies when the locking lock or the push lever 17 is moved into the advanced and blocking position of the locking lever 18. Because then the stop 21 comes to rest against the relevant locking lever 18 and consequently the path of the locking lock or the push lever 17 is limited when the nose 19 is inserted into the recess 20.
• the locking lock or the push lever 17 has a recess 22 for a bearing pin 23 of the intermediate element or the intermediate lever 5. With the aid of this recess 22 and the bearing pin 23, a further end position of the locking lock 17 is defined, namely the retracted and the locking lever 18 releasing position. Both end positions are shown in FIGS. 4 and 5.
• the thrust lever 17 moves back and forth between these positions, in a linear manner.
• the inlet insert or insert 13 contributes to its guidance with a corresponding guide surface 24.
• the push lever 17 can be connected to the intermediate lever 5 by riveting the push lever 17 to the intermediate lever 5 or by clipping it onto the intermediate lever 5. All other levers can be connected to one another in a similar manner, namely by riveting or clipping on. Likewise, in an embodiment in steel, an adhesive bond by welding is also conceivable if, for example, an articulated connection is not required.
