Problems solved by technology

This can cause functional disturbances in practice, for example, if the movement of the locking lever is blocked or delayed due to corrosion, aging, etc.
Furthermore, such functional disturbances cannot be detected, for example, for maintenance purposes, since the locking lever has to be removed for this, which is not possible in practice

Embodiment Construction

[0030] The drawing shows a motor vehicle door lock which is equipped with a locking device 1 , 2 , 3 comprising a rotary latch 1 , a locking pawl 2 and a pawl 3 . The locking devices 1 , 2 , 3 are mounted in a lock housing 18 . For this purpose, the rotary latch 1 has a corresponding shaft 4 and the locking pawl 2 is likewise equipped with its own shaft 5 .

[0031]A further basic configuration comprises an actuation lever mechanism 6, 7 comprising a release lever 6 and a further lever 7 or further levers connected thereto. In order to open the locking device 1 , 2 , 3 in the closed state in the figure, the release lever 6 must be rotated clockwise about its axis 8 by actuating the lever mechanism 6 , 7 , as clearly indicated by the arrow shown . This rotation of the release lever 6 causes the release lever 6 to act with the edge 9 on the pin of the locking pawl 2 . The clockwise movement of the release lever 6 in this process corresponds to a counterclockwise movement of t...

Abstract

The subject of the invention is a motor vehicle door lock equipped with a locking device (1, 2, 3), also equipped with an actuating lever mechanism (6, 7) acting on the locking device (1, 2, 3) and a lock Stop rod (12). The locking lever ( 12 ) locks the locking device ( 1 , 2 , 3 ) at least in the event of an acceleration force of a predetermined magnitude—for example in the event of an accident (collision accident). According to the invention, the blocking position of the locking lever ( 12 ) towards the locking pawl ( 3 ) of the locking device ( 1 , 2 , 3 ) acts on the pawl during normal operation and in the event of a crash and only opens the In normal operation, the locking pawl (3) and thus the locking device (1, 2, 3) are allowed to be in the released position.

Description

technical field [0001] The invention relates to a motor vehicle door lock having a locking device, an actuating lever mechanism with a release lever acting on the locking device and a locking lever which is at least in the event of an accident (collision, for example In the event of an accident) - locking of the actuating lever mechanism in the event of an acceleration force of a predetermined magnitude. Background technique [0002] Actuation rod mechanisms typically include one or more rods. Typically the inner actuation lever, outer actuation lever and release lever are used minimally. Furthermore, the actuating lever mechanism usually also includes a coupling lever. In this way the locking device can be opened if the actuating lever mechanism is loaded. For this purpose, the release lever generally acts on a pawl of the locking device and disengages the pawl from the associated rotary latch. The rotary latch then opens with the aid of a spring and releases the previo...
