Abstract

A rotary-latch lock (1), of which a rotary latch (8) has a fork mouth (9) for accommodating a mating locking part (6) which, in a locked position of the rotary-latch lock (1), is located in front of a blocking flank (16) formed by a fork-mouth leg (11), having a window-like opening (17, 25, 26) which promotes plastic deformation when the blocking flank (16) is subjected to increased loading, wherein the opening (17, 25, 26) forms a bending/extending web (18, 23, 24).
