Problems solved by technology

This is disadvantageous for the following reasons: the opening lever cannot be used for other door locks for example and the most basic is that the solution is relatively complicated
In addition, functional disturbances may occur if the emergency situation and the associated relative movement between the locking device and the opening lever, for example due to corrosion, are avoided or at least made difficult.

Embodiment Construction

[0035] The accompanying drawings show a motor vehicle door lock. The basic structure of the motor vehicle door lock comprises a housing 1 and a locking mechanism not shown. The locking mechanism consists of a pawl and a rotary latch in a conventional manner and can be opened in a known manner by means of the lever mechanism 2 , 3 partially shown in the drawing. For this purpose, the actuating lever mechanism 2 , 3 acts on the pawl and lifts the pawl out of the rotary latch, either directly or with a release lever interposed. As a result, the swivel latch is swiveled into its open position with the aid of the spring and releases the previously caught locking bolt.

[0036] Within the scope of this exemplary embodiment, the operating lever mechanism 2 , 3 is an outer operating lever mechanism 2 , 3 . The outer lever mechanism is equipped with an outer lever 3 and a connecting lever 2 . The connecting lever 2 is the first operating lever 2 of the operating lever mechanism 2 , ...

Abstract

The invention relates to a motor vehicle door latch, comprising a locking mechanism, an operating lever unit (2, 3) that operates on the locking mechanism, and a locking lever (4), which makes the operating lever unit (2, 3) mechanically ineffective when acceleration forces of a specified magnitude occur, for example during an accident, due to the deflection of the locking lever as a result of the acceleration forces, wherein a blocking means (5) that fixes the locking lever (4) in the deflected position thereof is associated the locking lever (4).

Description

technical field [0001] The invention relates to a motor vehicle door lock comprising a locking mechanism, an operating lever mechanism acting on the locking mechanism and a locking lever which passes through the locking lever under an acceleration force of a predetermined magnitude which occurs, for example in an accident. The deflection associated therewith renders the lever mechanism mechanically ineffective. Background technique [0002] The lever mechanism may be one or more levers. Typically such lever mechanisms include at least an inner lever and an outer lever. In addition, the operating lever mechanism usually also includes a coupling lever and a disconnecting lever. An integral part of the lever mechanism may also include one or more connecting rods. [0003] In any case, loading of the lever mechanism always opens the locking mechanism and releases the bolt previously held by the locking mechanism. The corresponding motor vehicle door can thus be opened. For ...
