Problems solved by technology

Since motor vehicle doors of this type usually have more or less hollow chambers, there is the danger that the aforementioned noises are amplified by possible resonances
This is disadvantageous, as closing / opening devices are often desired for increased operating comfort
However, if this operating comfort brings about additional or disturbing noise level correlations, there may be customers who consider this to be a disadvantage overall despite the operating comfort achieved

Embodiment Construction

[0020] exist figure 2 A motor vehicle door lock is shown in the installed position, which is generally equipped with a locking device 1 , 2 comprising a rotary latch 1 and an associated locking pawl 2 . The locking devices 1, 2 are equipped with a closing / opening device 3 to 7, which is here designed as an automatic closing device (soft closing automatic device) 3 to 7 and acts on the locking devices 1, 2 in the closing sense .

[0021] For this purpose, the closing / opening devices or automatic closing devices 3 to 7 have drives 3 , 4 , 5 which are designed as linear drives 3 , 4 , 5 in the exemplary embodiment. Here, the linear drive 3 , 4 , 5 essentially comprises a motor 3 a with an output shaft 3 b and a linear actuator 4 , 5 driven by this motor. Within the scope of this exemplary embodiment and without limitation, the linear drives 3 , 4 , 5 additionally have an intermediate transmission 3 c , 3 d between the motor 3 a and the linear actuators 4 , 5 . In this exempla...

Abstract

The invention relates to a motor vehicle door lock, comprising a locking mechanism (1, 2) and a closing / opening device (3 to 7) having a drive (3, 4, 5), wherein the closing / opening device (3 to 7) acts on the locking mechanism (1, 2) and the closing / opening device (3 to 7) comprises an interposed damping element (16).

Description

technical field [0001] The invention relates to a motor vehicle door lock with a locking device and a closing / opening device with a drive, wherein the closing / opening device acts on the locking device. Background technique [0002] Closing / opening devices for motor vehicle door locks have previously been used mainly in expensive cars. In this regard, reference is made to EP 1 319 780 A1, in which the electrical closing of the door or lid is carried out by means of a conventional electric motor. That is to say, the locking device moves into its end position or main locking position after reaching a defined functional position, usually after the pre-locking position. This results in a particularly comfortable design, since the operator only has to bring the corresponding door or flap into the pre-locking position, and the closing device then takes care of the complete closing process. [0003] In addition, so-called auxiliary opening devices are known, which ensure the elect...
