摘要

The lock has a safety catch (2), and springs (7a, 7b) attached to the safety catch. The springs strained with the opened safety catch expand for closing the safety catch. The springs expand with a predetermined speed and dampen a closing movement of the safety catch. A rotating latch dampening unit (13) is attached to the catch at one side, and a bolt dampening unit (16) is attached to the catch. The springs are designed as a pneumatic spring. The springs expand to an indexed position (17) of the safety catch. Ends (8, 9) of the springs are eccentrically connected with a rotating latch (1).
