Definitions

• the invention relates to a motor vehicle door lock, comprising a locking mechanism consisting essentially of a catch and a pawl, and an intermediate element interacting with the catch and / or the pawl, which transmits movements of the locking mechanism to a sensor, according to the main patent application DE 103 20 442.3.
• the intermediate element is designed as an intermediate lever and transmits movements of the rotary latch directly to the sensor.
• Comparable motor vehicle door closures are presented in DE 196 32 995 A1.
• DE 296 09 770 U1 proceeds. With the help of the sensor is usually queried whether the catch of the locking mechanism is in a certain position, usually the main latching position. Subsequently, for example, locking measures can be carried out.
• the main locking position of the catch or the locking mechanism is also used to switch off a drive for an associated motor vehicle door. This need arises with increasing importance in that more and more sliding door drives are used. With these you want to prevent the obligatory electric motor is unnecessarily burdened by a ride on block. In addition, associated mechanical noise is increasingly bothersome.
• the invention is based on the technical problem of further developing a generic motor vehicle door lock in such a way that a flawless signal delivery by the sensor is ensured with a simple and compact construction.
• the invention proposes in a generic motor vehicle door lock, that the intermediate element at least one controlled by the catch and store their movements of the rotary latch spring element and an acted upon by the pawl Sperr ⁇ pawl element whose combination movement is evaluated by the sensor , or the other way around.

• Decisive are therefore a spring element which stores movements and an element that follows the movement, on the one hand the catch and on the other hand the pawl, or vice versa.
• the connected movement of the two elements is evaluated by the sensor in order to derive a signal about the functional state of the locking mechanism.

• the rotary latch spring element releases the energy connected and recorded with the stored movement of the rotary latch only after sweeping over a predetermined actuation path of the pawl.
• This release of energy regularly leads to an associated movement of the rotary latch spring element, which ultimately triggers the sensor or transfers it to a state other than the existing functional state.
• This delayed sensor triggering as a result of the rotary latch spring element provided according to the invention has the advantage that the energy stored in the rotary latch spring element and the time of its delivery, and thus the triggering of the sensor, can be preset externally. It is conceivable here to relieve the correspondingly pretensioned rotary latch spring element by a lever or the like.

• the invention proposes, in this context, that when the locking pin enters into the locking mechanism or when the locking position is taken by the locking mechanism, the rotary latch spring element, which is inquired by the sensor, retains its defined initial position, which is also retained in the opened position of the locking mechanism until the Sperr ⁇ pawl element ensures a change of motion in the final position. Because the pawl element triggers a blockade of Dreh fallenfederelement.es in this initial position when taking the closed position of the locking mechanism, so that the rotary latch spring element can leave the initial position by the stored in itpermeabils ⁇ energy from the rotary latch and merges into an end position. This change of the Dreh fallenfederelement.es from the initial position to the end position is detected by the sensor as a switching signal and can be evaluated, for example, as taking the Haupttrastposition the Gesperres.
• the pawl element blocks the rotary latch spring element in the above-mentioned initial position until the pawl controlling the pawl element reaches a predetermined position.
• the rotary latch spring element In this predetermined position of the pawl, which follows the Sperrklinken ⁇ element, the rotary latch spring element is released and leaves its previously blocked initial position. As a result, the rotary latch spring element assumes the end position in a spring-assisted manner, because the kinetic energy received by the rotary latch and stored in the rotary latch spring element becomes free after the blockade has been released and the rotary latch spring element is transferred from the initial position to the end position.
• the rotary latch element is formed in two parts with spring storage and Abfragarm, wherein the spring storage stores relative movements of the rotary latch relative to the Abfragarm as kinetic energy.
• this kinetic energy can be recorded and stored consequently, it is necessary to hold the Abfragearm against the particular moving during the closing process of the locking catch.
• the pawl element regularly ensures this blockage of the interrogation arm.
• the pawl element is preferably designed as a non-rotatably connected to the pawl control lever.
• the associated pivoting of the locking pawl ensures that the control lever which is non-rotatably connected to the locking pawl also pivots and the rotary falling spring element or its interrogation arm blocked.
• the interrogation arm can no longer move with respect to the rotary catch moving further in the course of taking the closed position of the locking mechanism, so that the desired relative movement takes place between the rotary latch spring element or its interrogation arm and the spring accumulator resting against the rotary latch.
• the further movement of the rotary latch in the spring accumulator is converted into stored energy or tension energy of the spring accumulator.
• This tension energy or stored energy is only released when the control lever or the pawl element, the blockage of the rotary latch spring element in the course of taking the closed position of the locking ceases. This is usually the case when the pawl is in its primary ratcheting position or just before it.
