摘要

A rotary-latch lock in which a forked rotary latch is blocked against pivoting from a position locking a closing bolt. A spring loaded detent edge of a catch member engages behind a centrally directed catch edge extending from a circumferential edge of the forked rotary latch. In order to prevent an unintentional release of the rotary-latch lock, when the latter is subjected to dynamic stress, the catch edge is a limiting edge of an approximately U-shaped catch recess into which the detent end of the catch member engages. A rear edge of the detent end is located at a distance and opposite a limiting edge of the catch recess. In the event of oscillating movements of the forked rotary latch, the limiting edge butts against the rear edge of the detent end. The limiting edge and the corresponding rear edge are designed over their length of mutual contact as return surfaces which, during the time when they butt against one another, transmit an acceleration force tending to move the detent in the direction of engagement.
