Problems solved by technology

In addition, the actuating lever mechanism is not involved, so that the functional reliability of the actuating lever mechanism is not adversely affected
However, for this purpose, a particularly solidly manufactured locking element is used, which overall increases the weight of the known motor vehicle door lock.
[0006] It is therefore overall important not only to maintain the functional reliability of the locking element over the entire service life of the motor vehicle door lock, but also in the prior art so far no convincing solution has been provided for use, namely: making a reliable Functionality in harmony with the conflicting requirements of low weight and reduced costs

Embodiment Construction

[0032] The drawing shows a motor vehicle door lock, which is reduced to the components essential to the invention. First of all, the lock housing 1 is seen, which can be a lock box and / or a lock cover and whose function is to support and accommodate the individual elements which will be described in more detail below. Furthermore, there is a locking mechanism 2 , 3 , which in a known manner consists of a rotary latch 2 and a pawl 3 . The rotary locking fork 2 is mounted rotatably in the housing 1 on a pin which defines an axis of rotation 4 . The same applies to the locking pawl 3 , which is rotatably received on a pin in the lock housing 1 defining a further axis of rotation 5 .

[0033] The actuating lever mechanism 6 a , 6 b acts on the locking mechanism 2 , 3 . In this exemplary embodiment, the actuating lever mechanism 6a, 6b consists of two lever sections 6a, 6b of the outer actuating lever 6a, 6b which are articulated to one another. The rod sections 6a, 6b are hinge...

Abstract

The invention relates to a motor vehicle door lock equipped with a locking mechanism (2, 3), an actuation lever mechanism (6a, 6b) acting on the locking mechanism (2, 3), and a locking element (14). The locking element (14) disables the actuation lever mechanism (6a, 6b) when accelerating forces (F) of a defined magnitude occur, for example in the event of an accident. According to the motor vehicle door lock, the locking element (14) is a transmission lever (14) which can be impinged upon by a locking unit (11, 12) and is located between the actuation lever mechanism (6a, 6b) and the locking mechanism (2, 3).

Description

technical field [0001] The invention relates to a motor vehicle door lock which has a locking mechanism and additionally has an actuating lever mechanism acting on the locking mechanism and a locking element which occurs, for example, in the event of an accident (collision accident) The actuating rod mechanism is rendered inoperative at predetermined acceleration forces. Background technique [0002] Motor vehicle locking systems or motor vehicle door locks, which are acted upon by centrifugal forces or corresponding inertial / mass locking structures, are known in various forms. The point is to prevent unintentional opening of a motor vehicle door equipped with the motor vehicle door lock in the event of strong accelerations (eg, as occurs in a collision accident). Only in this way can it be ensured that the occupants in the motor vehicle are protected to the maximum extent and that for example safety devices such as airbags in the motor vehicle doors function precisely. ...
