Embodiment Construction

[0016] The figure shows a motor vehicle door lock with a locking mechanism (not shown in detail), which essentially comprises a rotary lock and a locking pawl. To act on the locking mechanism, the motor vehicle door lock has only figure 2 Trigger lever 1 recognizable in . The trigger lever 1 together with the blocking element or the blocking lever 2 is mounted rotatably about a common axis 3 in the lock housing 4 .

[0017] In order to open the locking mechanism, the trigger lever needs to be swung clockwise around its axis 3, such as figure 2 indicated by the corresponding arrows. Drives 4 , 5 for electrically opening the locking mechanism are provided for the clockwise pivoting movement of the trigger lever 1 . The drive means 4 , 5 consist of an electric motor 4 and a transmission wheel 5 which can perform a clockwise and anticlockwise rotational movement about its axis 6 initiated by the electric motor 4 .

[0018] The counterclockwise movement of the transmission wh...

Abstract

The object of the invention is a motor vehicle door lock, comprising a locking mechanism, an actuating lever chain (12, 13, 14) and a drive (4, 5) for electrically opening the locking mechanism. According to the invention, an additional drive (7, 8) is provided, which optionally transfers the actuating lever chain (12, 13, 14) in its "locked" position and only then generates an opening signal for the drive (4, 5) for electrically opening the locking mechanism.

Description

technical field [0001] The invention relates to a motor vehicle door lock having a locking mechanism, an actuating linkage, and an electric drive for electrically opening the locking mechanism. Background technique [0002] A motor vehicle door lock of the aforementioned construction is described, for example, in the applicant's patent application WO 02 / 31298 A1. In this case, not only can the locking mechanism be opened electrically, but at the same time a mechanical connection is provided between the actuating lever and the locking mechanism for emergency opening of the locking mechanism. This is also referred to here as the so-called Temporary Crash Redundancy (TCR). That is to say, even in so-called emergency operation or emergency opening, for example in the event of a crash, it is ensured that the locking mechanism can be opened mechanically, ie by means of the actuating lever of the actuating linkage. [0003] The electric opening of the locking mechanism by means o...
