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

[0028] The drawing shows a motor vehicle door lock which is equipped with a locking device 1 , 2 , 15 comprising a rotary latch 1 , a locking pawl 2 and a pawl 15 . Furthermore, the actuating lever mechanism 3 , 4 acting on the locking device 1 , 2 , 15 can be seen. The actuation lever mechanism 3 , 4 consists in this embodiment and without limitation of a release lever 3 and an actuation lever 4 . If the actuating lever 4 is loaded in a pulling manner corresponding to the direction of the arrow, the release lever 3 pivots clockwise about its axis 5 , as indicated by the arrow likewise shown in the figure.

[0029]During this process, the release lever 3 acts with the edge 6 on the pin 6 ′ of the locking pawl 2 . As a result, the locking pawl 2 pivots counterclockwise about its axis 7 in the direction of the arrow shown. As soon as the locking pawl 2 has released the pawl 15 , the pawl 15 can move away from the rotary latch 1 and the rotary latch 1 can be pivoted clockwise a...

Abstract

The subject of the invention is a motor vehicle door lock equipped with a locking device (1, 2, 15), also equipped with an actuating lever mechanism (3, 4) acting on the locking device (1, 2, 15) and a locking Rod (10). The locking lever ( 10 ) disables the actuating lever mechanism ( 3 , 4 ) 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 locking lever (10) blocks the actuating lever mechanism (3, 4) during non-deflected normal operation and in the event of a crash and only releases the actuating lever mechanism ( 3, 4).

Description

technical field [0001] The invention relates to a motor vehicle door lock with a locking device, an actuating lever mechanism acting on the locking device and a locking lever which is at least - for example in the event of an accident (collision accident) - - Blocking of the actuating lever mechanism in the event of an acceleration force of predetermined magnitude. Background technique [0002] Actuation rod mechanisms typically include one or more rods. Typically an inner actuation lever, an outer actuation lever and a release lever are used. 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 previously caught locking pin. The motor vehicle door coupled / coupled / associated with the latch can thus be opened. [0003] In the ev...
