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 ...
