ABSTRACT:
An end release type of buckle for safety belt harness in vehicles and a method of assembly wherein a channel shaped elongate chassis transversely supports a latch and a latch blocking element, the latter pivotal at one end and biased toward blocking the latch. A closure plate biased to follow insertion and removal of a buckle tongue is reciprocably mounted for longitudinal movement to the web of the chassis. A release slider is provided which reciprocates to remove the blocker against its bias and to depress or open the latch. A tubular case encloses and detentably assembles the chassis and operably guides the release slider while supporting the operating bias applying elements. A cup-like cover is pressed longitudinally over the case and is detentably located and secured to said case. When not in use the latch is held open by the closure plate. When a tongue is pressed into the buckle the closure plate retreats from blocking the entry slot and the latch obeys the bias to lock. Upon locking the tongue, the blocker bar secures the latch against withdrawal until the release slider depresses the latch after tilting the blocker bar away from the latch.
