Embodiment Construction

[0024] figure 1 A top view of a locking device of a motor vehicle lock is shown. The locking device comprises a rotary latch 1 and a locking pawl 2 . The at least partially—preferably primarily—metal rotary latch 1 is latched in the main latching position by the at least partially—preferably primarily—metal locking pawl 2 , as shown in the figure. A locking pin 3 fastened to the body of the motor vehicle is held in an opening 4 of the rotary latch 1 . The rotating concave lock part 1 and the locking pawl 2 are fixed on the locking plate 5 in a rotatable manner. The rotary latch 1 is rotatable about its axis 6 . The pawl 2 is rotatable about an axis 7 . The preferably metallic locking plate 5 , also referred to as a lock box, likewise has an opening 8 through which the locking bolt 3 can enter and exit the lock. The rotary latch has a protruding locking surface 9 which, in the locked state in the main locking position, is pressed against a locking surface 10 of the pawl 2 ...

Abstract

The invention relates to a lock for a door or hatch, comprising a locking mechanism that has a rotary latch and at least one pawl for latching the rotary latch. The rotary latch has a protruding blocking surface and a pocket-shaped recess or pocket adjoining the protruding blocking surface. The pocket-shaped recess extends arcuately from the protruding locking surface, whereby a "V"-shape is avoided. The arcuate shape thus prevents the formation of zones in which a higher percentage of dust may accumulate. If there is no increased accumulation of dust, less dust may deposit between surfaces and cause creaking noises.

Description

technical field [0001] The invention relates to a lock for a door or a cover / hatch / flap, said lock having a locking device comprising a swivel latch and a pawl for locking the swivel latch. The rotating concave lock part includes a protruding locking surface and a concave curved recess adjacent to the protruding locking surface. Background technique [0002] Such locks are used to temporarily close openings in motor vehicles or buildings by means of doors or flaps. In the locked state of such a lock, the rotary latch ring grips a generally bow-shaped locking pin which, in the case of a motor vehicle, is usually fastened to the body. If the rotary latch is pivoted from the open position to the locked position, the rotary latch is finally locked by the locking pawl. In this way, the rotary latch can no longer be pivoted in the direction of the open position and the locking pin can no longer leave the locking device. For opening it is necessary to move the pawl out of the lo...
