摘要

The lock has a locking mechanism provided with a rotary latch (4), a forward notch pawl (13) for latching the rotary latch, and a main notch pawl (6) for latching the rotary latch. The forward notch pawl is pre-stressed by a spring (22) in a direction of the rotary latch. A rotatable blocking lever (8) blocks backward movement of the main notch pawl in a locking position, when the spring is inoperative. The spring is fixed between the forward notch pawl and the blocking lever. A hook (8a) of the blocking lever works together with a hook of the main notch pawl.
