But this is disadvantageous when passengers need to leave the motor vehicle immediately
That is to say, in order to increase the crash safety of the lock mechanically, the known solutions ensure that the associated motor vehicle door lock is blocked without problems and prevent accidental opening, but they increase the immediate access to the lock at the end of the accident process.

Embodiment Construction

[0033] A motor vehicle door locking device is shown in the drawings. In its basic structure, the door locking device comprises a housing 1 and locking mechanisms 2 , 3 . The housing 1 can here be made of plastic and can be designed as a plastic injection-molded part. Of course this is only exemplary and should not be construed as limiting. The locking mechanism 2 , 3 comprises a rotary latch 2 and a pawl 3 interacting with the rotary latch 2 . The locking mechanism 2 , 3 and the housing 1 together define a motor vehicle door locking device 1 , 2 , 3 which also includes further elements to be described below. The motor vehicle door locking devices 1 , 2 , 3 cooperate in a known manner with pin bolts (not shown). In this case, the motor vehicle door locking device 1 , 2 , 3 can be arranged on or in a motor vehicle door (not shown in detail), while the locking bolt is located on the associated motor vehicle body, or vice versa.

Abstract

The present invention relates to a motor-vehicle door lock which is provided with a catch (2,3), with an actuating-lever mechanism (5, 6) which acts on the catch (2, 3). There is also a locking lever (7) which, together with the actuating lever (5), renders the actuating-lever mechanism (5, 6) inactive when accelerating forces of predetermined magnitude occur, for example in the event of a crash. According to the invention, the actuating lever (5) and locking lever (7) disable the actuating-lever mechanism (5, 6) mechanically, as a result of the accelerating forces occurring, by associated deflection. Following dissipation of the accelerating forces, the actuating lever (5) and locking lever (7) reconnect the actuating-lever mechanism (5, 6).

Description

technical field [0001] The invention relates to a motor vehicle door locking device comprising a locking mechanism, an operating lever mechanism acting on the locking mechanism and a locking lever which deactivates the operating lever mechanism in the event of an acceleration force of a predetermined magnitude, for example in the event of an accident. Background technique [0002] The lever mechanism can be one or more levers. Typically such lever mechanisms comprise at least one inner lever and one outer lever. In most cases, the operating lever mechanism also includes a coupling lever and a disconnecting lever. Regardless, loading the lever mechanism serves to open the latch mechanism and release the previously held pin bolt. The associated motor vehicle door can thus be opened. For this purpose, the release lever usually acts on a catch which interacts with the rotary latch as two components of the locking mechanism. The catch is lifted from the rotary latch and the r...
