The buckle intended to join a belt to an anchorage point consists, among other things, of a latch (10) and of a keeper which comprises a base (20), a lock (30), an ejector guide (40), an actuating button (50), preferably a protective covering (60) and, if necessary, a closure detector (80) and an il
The buckle intended to join a belt to an anchorage point consists, among other things, of a latch (10) and of a keeper which comprises a base (20), a lock (30), an ejector guide (40), an actuating button (50), preferably a protective covering (60) and, if necessary, a closure detector (80) and an illumination device (90). This buckle comprises operating and locking means (70) which cause the lock to cooperate with the button and with the base either to allow opening of the locked buckle when the latter is subjected to a tensile force less than a given limit or to ensure permanent locking of the locked buckle when the latter is subjected to a tensile force at least equal to a predetermined value and prevent opening thereof. Application to safety belts for automotive vehicles.

Safety-belt buckle in particular for a land-type automotive vehicle, which is intended to join a strap to an anchorage point and which consists, in particular, of a latch (10) and of a keeper comprising, among other things, a base (20) and, carried by the latter, a lock (30), an ejector guide (40),
Safety-belt buckle in particular for a land-type automotive vehicle, which is intended to join a strap to an anchorage point and which consists, in particular, of a latch (10) and of a keeper comprising, among other things, a base (20) and, carried by the latter, a lock (30), an ejector guide (40), an actuating button (50) and, if necessary, a protective covering (60), in which this base (20) defines a channel (200) intended to receive at least partially the latch (10), this lock (30) being mounted on this base (20) by means of an articulation (230) which allows it to move in practice only by pivoting so as to be movable between at least two positions towards which it is elastically biased, a first releasing position where the latch (10) is unlocked and the lock (30) is away from the ejector guide (40) and a second retaining position where the latch (10) is locked on the keeper by the lock (30), this ejector guide (40) having a seat (400) intended to receive the latch (10) at least partially and being mounted on this base (20) so as to be displaceable there in translation such that it is movable between a rest position towards which it is normally elastically biased and which it occupies when the lock (30) is in its first position and a set position which it occupies when the lock (30) is not in its first position, this actuating button (50) being mounted on this base (20) so as to be displaceable there in translation such that it is movable between an inactive position towards which it is normally elastically biased and an active position in which it causes the latch (30) to pass into its first position, characterized in that this lock (30) is deformable elastically towards a third permanently locked position where it is directly and positively locked to the base (20) only through a direct engagement of a lock edge (71) with a permanent-locking notch (72) of the base (20) when it occupies its second position and wherein the locked buckle is subjected to a force tending to open it which is greater than a given value and in that operating and locking means (70) associate this actuating button (50) and this lock (30) and this base (20) such that in a first mode, when a force tending to open the locked buckle does not exceed this given value, when the actuating button (50) passes from its inactive position to its active position, the lock (30) moves from its second to its first position so as to release the latch (10) and the ejector guide (40) passes from its set position to its rest position so as to eject the latch (10) released from the base (20) and, in a second mode, when a force tending to open the locked buckle is equal to or exceeds this given value, the actuating button (50) is unable to pass from its inactive position to its active position so as to dislodge the latch (30) from its third position, cause it to pass through its second position and reach its first position.
