Abstract

A central belt lock, particularly for a parachute harness, includes a housing, a main pin or journal which is manually rotatable and axially movable therein, and an anchor plate which cooperates with a plurality of retaining bolts for the belt attachment or coupling members. There is dealt with the problem of allowing the belt attachment members to be released and thus disconnected from the lock even if the parachutist for some reason is unable to actuate the lock manually, after making a jump over the sea. Therefore, a central belt lock is provided to be activated by sea water and can be released thereby, without affecting the function thereof when operated manually. For this purpose, the main journal (2a) has at least one longitudinal bore in which a push rod (12) is mounted so as to be longitudinally movable. An actuator (20, 27) is associated with the push rod and is actuated when coming into contact with water, axially moving the push rod (12) and hence the anchor plate (5) with the retaining bolts (6). Preferably, the rotary handle (11a, 11b) of the belt lock contains an inner space (16) in which the actuator (20, 27) and the push rod as well as an angle lever serving as tran…
