ABSTRACT:
A buckle fastener for a safety belt including a housing having a guiding channel for guiding a tongue into and from the housing, a latching member movable transversely to the insertion channel for selective engagement and disengagement with a recess formed in the tongue, a leaf spring member biasing the latching member into engagement with the recess in the tongue, and a pressure key slidably guided in the housing in a direction parallel to the guiding channel. The pressure key is provided with ramp means engaging the latching member for pushing the latching member out of engagement with the recess in the tongue when said pressure key is depressed. The leaf spring has one end secured to said pressure key and its opposed free end bearing on the latching member. The leaf spring moves simultaneously with the pressure key when it is depressed. An abutment member is connected with the housing and has an edge extending transversely relative to said leaf spring and is positioned in such a manner in relative to said leaf spring that, upon partial depression of said pressure key, an intermediate portion of said leaf spring abuts against the edge and upon further depression of said pressure key the free end of said leaf spring is lifted off the latching member.
