Shock proof buckle for safety belts

In a buckle for a safety belt, a pivotable latch (13-17) is arranged, relative to the push-in tongue (4), in such a way that the ejector force (11), or the belt force loading the tongue, urges the latch out of engagement. Provided to prevent this, in the closing position, is a securing device which, in one position (FIG. 1), holds the latch firmly in the latching position and, in another position (FIG. 2), releases the latch for opening. According to the invention, this securing device is designed as a pivoting lever (21), in order, on the one hand, to increase the degree of safety and, on the other hand, to lessen the opening force, at a moderate production outlay. The pivoting lever is mounted in such a way that it cannot leave the securing position even under shock stress from any direction whatever.

Buckle for a safety belt

The invention relates to a buckle for a safety belt, which buckle contains two symmetrically disposed swivel latches (9) which cooperate with indentations (11) lying opposite one another in the insertable tongue (7). In order to ensure that both swivel latches will always conjointly engage in the indentations in the insertable tongue, according to the invention the swivel latches are joined together by a drive arrangement so as to make a common movement. This drive arrangement may be formed by two levers (12,13), each of which is joined to one swivel latch (9) and whose ends are joined so as to make a common movement.

A safety belt fastening in which the male member includes an enlarged head for laterally pivoting a spring biased locking member operating in a recess of at least one of two plates joined to form the female member of the fastening. The locking member moves to a position aligned substantially with the insertion movement of the head until the head passes. A guide surface including a pin in the female member laterally displaces the male member at an incline to cause pivotal rotation of the locking member during insertion, thereby effecting a force economy compared with that effected by a straight in insertion. When the locking member rotates, it pivots about its rear face in conjunction with an oppositely aligned recess face in a bearing-like action, at least one of these faces being convex. Preferably, the rear face of the locking member is made of drawn steel. The locking member is manually rotatable for release. An injector spring separates the male and female members at the time of release.
