<p>The safety-belt buckle has a belt andpiece inserted in the lock and with a tongue secured by it. It comprises a metal frame with lateral recesses accommodating the trunnions of a lock for the tongue. Also included are an ejector for the tongue, a support keeping the member in the locked position, and a release button, all spring-loaded. The lock is a plate (8) with an open recess at the rear. Each recess (18) in the frame (7) for the trunnions (19) is an elongated hole extending alongside the path of the tongue (4) and parallel to its direction of movement. Seen in the insertion direction of the tongue, the bottom edge of each hole joins onto a ramp face (27). Dimensions of holes and trunnions are such that the latter can slide in the direction of movement of the tongue in the locked position, but have no free movement in the lateral direction. -</p> |
