Patent ID: 6871517

Claim:
A buckle comprising a fastener and a latch displaceable linearly relative to one another between engaging and disengaging positions and configured so that the latch and fastener are locked against displacement relative to one another simultaneously with reaching the engaging position, which corresponds to a locking state of the buckle, and a locking assembly mounted in the fastener and operative to unlock the latch from the fastener so that the latch is capable of deflecting in response to the external force, wherein the unlocked latch and fastener define a release state of the buckle, in which the latch and the fastener are enabled to slide linearly away from one another to the disengaging position, and the locking assembly includes a locking element and a cam cooperating with one another so that when the fastener and the latch are sliding linearly to the engaging position, the locking element being displaceable frontward to allow the latch and fastener to engage one another, the locking element being automatically displaceable backwards simultaneously with the engagement of the latch and the fastener to prevent further displacement thereof.
