<p>A method of making a safety belt buckle having a rigid base plate defining a belt tongue insertion path, belt tongue locking means having first component fixed to the base plate and a second component movable relative to the first component to lock an inserted belt tongue in the buckle, and an actuator element disposed on the base plate and movable relative to the base plate to cause the second component to release the tongue. The method comprises the steps of forming the first component and the actuator element as a one-piece unit which the first component and the actuator element are interconnected by the frangible connections, mounting the one-piece unit on the base plate, and thereafter moving the actuator element relative to the base plate and first component to cause the frangible connections to break.</p> |
