Abstract

A buckle for a safety belt has a body in which a passageway is provided for receiving a tongue and a latch member movable transversely of the passageway between a latching position in which it engages with the latching formation to retain the tongue in the passageway, and a release position in which the tongue is displaceable by an ejector outwardly from the passageway from its retained position, the latch member being biased into its released position by a spring. A first toggle member pivots about a fulcrum on the latch and abuts a second toggle member which pivots about a fulcrum on the body. The toggle members have a first stable position in which the latch member is held in its latching position against the action of its biasing spring.
