Problems solved by technology

However, the disadvantage of this solution known from the prior art is that it only prevents the rattling noise between the rotary locking fork and the locking bow in the closed position, but cannot reduce it in the open locking position and thus release the rotation. Noise generated when locking the fork

Embodiment Construction

[0024] figure 1 A possible embodiment of the buffer unit 13 with a braking element 13.1 according to the present invention is shown, wherein the braking element 13.1 is arranged in the buffer groove 13.2. The buffer groove 13.2 is configured as a material gap in the form of a long hole. The brake element 13.1 protrudes from the buffer groove 13.2 of the buffer unit 13 with one end. The protruding end is at figure 1 The structure is hemispherical. The hemispherical portion of the braking element 13.1 can be in contact with the rotating lock fork, so that the braking force is transmitted to the rotating lock fork and the noise when the rotating lock fork is unlocked can be reduced.

[0025] in figure 2 Shows along figure 1 A cross-sectional view of the embodiment of the buffer unit 13 taken along the section line A-A. On the buffer unit 13, the brake element 13.1 is formed integrally with the buffer unit 13. The hemispherical area of ​​the braking element 13.1 extends from the ...

Abstract

The invention relates to a motor vehicle lock (10) for a movable vehicle part, in particular for a door, flap, tailgate or bonnet, said lock having a lock housing (11) and a rotary latch (12) that ismovably provided on the lock housing (11), and the rotary latch (12) being movable into an open position and at least one engaged position (I). In addition, at least one buffer unit (13) is provided on the lock housing (11) and at least one braking element (13.1) is located on the buffer unit (13), such that at least some portions of the braking element (13.1) can be brought into contact with therotary latch (12), at least while the rotary latch (12) is moving into the open position.

Description

Technical field [0001] The invention relates to a motor vehicle lock for movable parts of a vehicle, in particular for doors, sliding doors, hatches, rear covers or engine hoods, according to the independent claim 1, and a method according to the independent claims The described method for reducing opening noise. Background technique [0002] A lock is known from the prior art, and the lock has a vibration damping layer or a jacket on the rotating lock fork, thereby reducing interference noise. The document DE 10 2006 028 423 A1 discloses a rotary lock fork with such a casing, wherein the rotary lock fork is formed with a vibration damping layer for reducing noise, especially in the region of the fork-shaped entrance slit. However, the disadvantage of this solution known from the prior art is that it only prevents the squeaking noise between the rotating lock fork and the lock bow in the closed position, but cannot reduce the open lock position and thereby release the rotation. ...
