Embodiment Construction

[0023] The figure shows a motor vehicle door lock, which can be designed as a motor vehicle side door lock. Usually, however, it can also be a hatch lock of a motor vehicle. In each case, the motor vehicle door lock concerned is equipped with a locking device 1 , 2 which essentially comprises a rotary lock 1 and a pawl 2 . The pawl 2 has an abutment surface 3 for abutting the rotary latch 1 in the closed state of the locking device 1 , 2 . Within the scope of the exemplary embodiment, the abutment surface 3 is designed as an arcuate contour, in particular a circular arcuate contour 3 . The locking pawl 2 is supported around a rotary shaft 4 . Such as figure 2 As shown, the axis of rotation 4 is defined by a pin or bearing bolt for receiving the locking pawl 2 in a rotatable manner relative to the corresponding lock box 5 .

[0024] according to figure 1 , the abutment surface or arc-shaped profile 3 is along the opening direction of the locking claw 2—that is, the lockin...

Abstract

The invention relates to a motor vehicle door lock and a corresponding method for operating the motor vehicle door lock, the motor vehicle door lock having a locking device (1, 2), the locking device mainly comprising a rotary locking fork (1) and a locking pawl (2), Wherein, the locking pawl (2) is provided with an abutting surface (3) for the rotating locking fork (1) to abut on it in the closed state of the locking devices (1, 2). According to the invention, the locking pawl (2) is provided with a support element (6) that delays the opening of the locking device (1, 2), so that the rotary locking fork (1) slides along the abutment surface (3) until Only a predetermined degree of opening (angle α) is disengaged from the locking pawl (2).

Description

technical field [0001] The invention relates to a motor vehicle door lock, the motor vehicle door lock has a locking device, the locking device mainly comprises a rotary lock fork and a locking pawl, wherein the locking pawl is equipped with an abutment surface, the abutment surface is used for closing the locking device In the state, lean against the rotating lock fork. Background technique [0002] In the motor vehicle door lock of the aforementioned configuration, as described in DE 10 2009 029 031 A1, it is designed such that the locking pawl has a locking moment in the main locking position of the locking device, which locking moment is locked Converted to the opening torque during the opening of the device. In this way, the relatively quiet opening of the known motor vehicle door lock is to be provided. In practice, the main problem with such motor vehicle door locks is that during the opening process the rotary catch and / or the pawl are released more or less suddenl...
