Embodiment Construction

[0025] figure 1 Shown is a lock 1 , here a motor vehicle door lock, which has a locking mechanism 6 consisting of a rotary latch 2 and a pawl 4 . In the closed position shown, the rotary latch 2 with the opening 7 surrounds the locking bolt 3 , wherein the rotary latch 2 is pivotable about the pivot axis 5 . To fix this position, the pawl 4 is swiveled such that its projection 11 abuts against the rotary latch 2 and forms a targeted and precisely defined contact area in the region of the notch, by which the rotary latch is blocked. The lock part swings back 2 times. All these lock parts are arranged in a lock housing 10 which has a guide link 8 for the lock bolt 3 , the input side of which is referenced 9 .

[0026] The rotary latch 2 generally has a casing made of plastic, wherein the contact area of ​​the rotary latch 2 with the locking bolt 3 is generally not provided with a casing, so that metal-to-metal contact occurs here when the pawl 4 falls in. The pawl 4 can also ...

Abstract

The invention relates to a lock for a motor vehicle or a building, said lock being equipped with a rotary latch (2) rotatably supported in the lock housing (10) about a locking bolt (3), wherein the lock housing (10) has a slotted guide (8) for the locking bolt (3), said slotted guide having at least one spring lip (15) on the insertion side, which spring lip reaches into the slotted guide and cushions the locking bolt (3), said spring lip having creaking protection (17) that partially covers the surface (16) of the spring lip, wherein the spring lip (15) has a bounding bead (20) at the free end (18) and wherein the creaking protection (17) is designed as a sheet metal clamp (21) that can be attached to the spring lip (15) in front of the bounding bead with a preload.

Description

technical field [0001] The invention relates to a lock for a motor vehicle or a building, comprising a swivel latch mounted in a lock housing so as to be rotatable about the lock bolt, wherein the lock housing has a guide slide for the lock bolt The guide slot has at least one elastic lip protruding into it on the insertion side and exerting an elastic action on the locking bolt, said elastic lip having a noise protection device which at least partially covers its surface. Background technique [0002] In particular, locks which are incorporated or arranged in moving parts generate noise, especially rattling, during this relative movement between the parts, which should be avoided from a comfort point of view. The prior art discloses various solutions capable of counteracting this noise nuisance. This is particularly important for motor vehicles, since in motor vehicles the aforementioned noises are generated during operation mainly between the rotary latch and the locking ...
