Embodiment Construction

[0023] The figure shows a motor vehicle door lock, which can be designed as a motor vehicle side door lock. But it can usually also be a motor vehicle rear hatch lock. In all cases, the relevant motor vehicle door locks are equipped with locking devices 1 and 2, which mainly include a rotating lock fork 1 and a locking pawl 2. The locking pawl 2 has an abutting surface 3 for the rotary lock fork 1 to abut against the abutting surface when the locking devices 1 and 2 are closed. The contact surface 3 is designed as an arc-shaped contour and in particular a circular arc-shaped contour 3 within the scope of this exemplary embodiment. The locking pawl 2 is supported around the rotating shaft 4. Such as figure 2 As shown, the rotation shaft 4 is defined by a pin or a supporting bolt, which is used to receive the locking pawl 2 in a manner capable of rotating relative to the corresponding lock box 5.

[0024] according to figure 1 , The abutment surface or arc-shaped contour 3 is a...

Abstract

The present invention relates to a vehicle door lock and an associated method for the operation thereof, wherein the vehicle door lock is equipped with a locking mechanism (1, 2), which essentially consists of a catch (1) and a pawl (2). The pawl (2) has a contact surface (3) for the catch (1), which rests on said contact surface when the locking mechanism (1, 2) is closed. According to the invention, a supporting element (6), which delays the opening of the locking mechanism (1, 2), is associated with the pawl (2), so that the catch (1) glides along the contact surface (3) up to a predetermined opening angle (angle α) until is it is released from the 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 includes a rotating lock fork and a locking pawl. The locking pawl is equipped with an abutment surface for closing the locking device. It rests on the rotating lock fork in the state. Background technique [0002] In the motor vehicle door lock constructed as described at the beginning, as described in DE 10 2009 029 031 A1, it is designed such that the locking pawl has a locking torque in the main locking position of the locking device, and the locking torque is The opening period of the device is converted into an opening torque. In this way, a relatively quiet opening of the known motor vehicle door lock should be provided. In fact, the main problem in this type of motor vehicle door lock is that the rotating lock fork and / or the locking pawl are more or less suddenly released and move away from each other during the opening ...
