<p>A safety belt buckle formed of two plates (3, 4) fastened together and having two pawls (18) laterally movable to engage catch areas (6b) of a tongue (6). A spring (19) which urges pawls (18) towards each other has a steep characteristic. Pawls (18) slide within lateral slots (16, 17) formed in plates (3, 4). These slots which are so short that the front end (6a) of tongue (6) can only just be moved past the pawls (18). These refinements are to prevent single-pawl latching. There is an ejector (13, 15). <IMAGE></p> |
