Safety belt clasp with notched tongue and fastener - has two fastener plates forming tongue guide and containing pivot cock

摘要

A side notched tongue is accepted by a fastening component and two fastener plates form a guide for the tongue. They contain a pivot lock which acts with the indentation in the tongue. Two cut-outs in the fastener plates allow the lock to pivot about an axis normal to the plates, while it is forced into the tongue guide by spring force. There are fixed guide sections between the fastener plates acting with the tongue side faces and these give the tongue a guide direction coinciding with its longitudinal direction in the position in which it is locked in the clasp. The side of the pivot lock facing the tongue in its open position includes an expanding angle with the tongue longitudinal direction. The guide direction is inclined in that region in which the thicker section of the tongue passes by the lock and shortly before reaching the locking position it transfers into the direction coinciding with the tongue longitudinal direction.
