LOCK FOR SAFETY BELTS

摘要

Lock for safety belts having at least two hip strap parts and two shoulder strap parts, said lock comprising a lock housing to be attached to one hip strap part and enclosing a manually releasable lock mechanism (18), a lock tongue (11) to be attached to the other hip strap part, which can be inserted into an insert opening in the lock housing for co-operation with the lock mechanism, and a fitting (12; 13) for each shoulder strap part to be connected with the lock housing and the lock tongue by these elements being mutually lockingly engaged. In the lock housing there is provided a blocking shoulder (41, 42) which is spring-biased to project partly into the insert opening so as to prevent insertion of the lock tongue to engage the lock mechanism. Moreover, the lock housing forms an insert opening for each fitting to be inserted transversely through the insert opening for the lock tongue, the fitting being engaged with the blocking shoulder and the blocking shoulder being displaced from the insert opening for the lock tongue against the spring bias. The fittings each form an opening (53), the lock tongue being passed through said openings to retain the fittings in the lock housing when the lock tongue is engaged with the lock mechanism.
