Motor vehicle door lock

Abstract

The invention relates to a motor vehicle door lock comprising a locking mechanism consisting essentially of a rotary latch and a pawl, further comprising an actuation lever mechanism (2a, 2b) that acts on the pawl, and a child safety device (3) that includes a child safety lever (4) to which the force of a spring (5) is applied. According to the invention, the child safety lever (4) and the spring (5) are designed as a subassembly (4, 5).

Description

technical field [0001] The invention relates to a motor vehicle door lock having a locking mechanism mainly comprising a rotary lock fork and a pawl, an actuating lever mechanism acting on the pawl and a child safety device having a spring-applied Child safety bar, wherein the child safety bar selectively deactivates / activates the door inner handle subordinate to the actuating lever mechanism depending on its "child safety open" or "child safety closed" position, while the outer door handle remains active unchanged. Background technique [0002] In motor vehicles, the rear side door can typically be actuated by means of a child safety device in such a way that the inner door handle is disabled in its "child safety open" position. However, the side door can still be opened from the outside because the outside door handle remains activated unchanged. The "child safety open" position of the child safety device or child safety bar corresponds to the selective deactivation of t...

Problems solved by technology

[0007] Although the designs of child safety devices known to date are convincing in terms of their function, they are structurally complex because, in addition to the child safety bar, at least an additional spring must be realized by means of which the child safety bar is secured. Occupy both end positions or only one end position
