Safeguarding buckle for a safety belt

Claim 1

Buckle for a safetybelt, especially of motor vehicles used on land, which is intended for connecting a band to an anchorage point and which is composed, among other things, of a latch (10) and of a keeper comprising particularly a base (20) which delimits a channel (200) for receiving the latch (10) at least partially and which is equipped with a nose (210), on which the latch (10) can catch directly when it is locked on the keeper, and, carried by this base, an ejecting guide bolt (30) which delimits a receptacle (300) for receiving the latch (10) at least partially and which is mounted on the base (20) movably between a first retaining position, towards which it is normally stressed elastically, and a second position, towards which it is pushed momentarily during the introduction of the latch. (10) into the keeper for locking it, and an actuating button (50) mounted on the base (20) movably in terms of translational motion parallel to the receptacle (300) between an inactive position, towards which it is normally stressed elastically and which it occupies when the ejecting guide bolt (30) is in its first position, and an active position for causing the ejecting guide bolt (30) to pass from its first position to its second position in order to release the latch (10) from the keeper, wherein the channel (200) and the receptacle (300) are inclined relative to one another and are oriented in such a way that the channel (200) has a slant rising in the direction of the receptacle (300), the ejecting guide bolt (30), when it moves from its first position to its second position, follows a path in the form of a broken line, first approximately parallel to the receptacle (300) and then oblique relative to the latter, and vice versa, and it possesses means (40) for safeguarding the bolt (30) in its first position, for inserting and retaining the latch (10)in the receptacle (300) of the ejecting guide bolt (30) and for guiding the ejecting guide bolt (30) on its path in the form of a broken line when it moves from one of its two positions to the other.
