Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and pawl, and with at least one sensor for monitoring the rotary latch.
• a motor vehicle door lock which has a locking lever controlled by the rotary latch.
• the locking lever is mounted axially with the rotary latch and follows its rotary movements.
• the locking lever and the catch are connected to each other.
• the locking lever is a two-arm lever with a blocking arm and interrogation arm, the latter carrying a sensor which interacts with a detection device in order to be able to interrogate the position of the rotary latch.
• the invention is based on the technical problem of further developing a motor vehicle door lock of the design described at the outset in such a way that the rotary latch position can be interrogated properly, taking into account a particularly inexpensive and universally usable design of the sensor.
• a generic motor vehicle door lock is characterized in that an intermediate bearing on the catch element is provided, which transmits the movements of the rotary latch to the sensor.
• the catch and intermediate element thus represent separate components, the intermediate element just resting on the catch to transmit their movements to the sensor.
• This system can be accomplished, for example, by prestressing the intermediate element in the direction of the catch, which may be ensured by a spring.
• the intermediate element thus ensures that the sensor is decoupled from the rotary movements of the rotary latch, so that an inexpensive switch or microswitch can be used as the sensor. Any contamination and / or damage to the rotary latch therefore no longer play a role, because such interferences are not transmitted to the sensor by the intermediate element. This also applies to any icing, because ' the intermediate element is usually protected in the interior of a lock housing or lock case.
• the intermediate element is usually an intermediate lever that is designed to be rotatable about an axis.
• This intermediate lever or interrogation lever has an essentially circular to oval design, the axis of the intermediate lever and an axis of the rotary latch being arranged essentially at right angles to one another. This makes it possible to position the sensor outside of the rotary latch plane, for example on one leg of the lock housing or lock case. The position of the sensor can therefore be determined more or less freely. This opens up the option of adding additional sensors to the sensor if necessary To combine or combine sensors and electrical devices and / or an existing printed circuit board.
• the intermediate element has at least one interrogation contour for the sensor.
• a switch or microswitch is usually used as the sensor.
• the latter has an extension arm which can be actuated by the rotary latch, wherein this extension arm usually interacts with a projection on the rotary latch.
• the insert has the necessary hole for receiving an axis for the intermediate element or the intermediate lever.
• the insert may be an inlet insert, that is to say an insert which usually defines the inlet mouth. In this way, there is no need for complex storage measures for the intermediate element on the lock housing or lock case. Rather, insert and intermediate element can form a prefabricated assembly.
• the intermediate element has a receptacle for a locking lock.
• the locking lock can be coupled to the intermediate element.
• the locking lock ensures that one or more locking levers are mechanically blocked when the rotary latch is open.
• the intermediate element has a dual function in this context. On the one hand, it ensures that the sensor or switch or microswitch correctly reproduces the position of the catch. On the other hand, the intermediate element ensures, via the associated locking lock, that when the catch is open, the
• Locking lever or altogether a locking lever mechanism is mechanically blocked.
• a motor vehicle door lock is made available which keeps away any possible negative influences of the rotary latch on the sensor with the aid of the intermediate element.
• the intermediate element or the intermediate lever opens up the possibility of placing the sensor at practically any point without having to take into account the movement and arrangement of the catch. This is where the main advantages can be seen.
• Fig. 3 shows the motor vehicle door lock according to FIGS. 1 and 2 with an insert mounted in the lock housing for holding the intermediate element and
• 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 is designed as an intermediate lever 5 with an essentially circular to oval overall design.
• any intermediate elements 5 can be realized 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, gear wheels, friction wheels, Bowden cables, etc.
• the least constructive effort 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 essentially vertically in comparison. This angular arrangement of the two axes 6, 7 results in that the intermediate element or the intermediate lever
• 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 carries out a clockwise rotation indicated by an arrow in FIG. 2.
• 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 within the scope of the exemplary embodiment on an insert 13 for the lock housing or the lock case 12.
• 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 locking lock 17 mechanically blocks a locking lever 18 when the rotary latch 1 is open (see FIG. 4).
• the locking lock 17 designed as a thrust lever 17 engages with a front nose 19 in a recess 20 of the locking lever 18.
• connection between the push lever 17 and the intermediate lever 5 can be made by clips, screws, rivets or
