Abstract: A seat belt latch buckle includes a buckle body that releasably accepts and latches a buckle tongue. The buckle body includes a frame, a latch plate having a latching projection and pivotable in the frame, a release member to release the tongue, and an ejector to eject the released tongue. A control member is slidable on the latch plate between first and second positions. In the first position the control member is engaged between a portion of frame and the latch plate to positively lock the latch plate in the latched position. The release member slides the control member to the second position, in which it no longer prevents the latch plate from moving to the release position, before it engages the latch plate to pivot it and release the tongue.

Abstract: The present invention discloses an improved coupling system capable of releasably joining two or more of a variety of cooperative male/female mating items to be temporarily joined and released by a remotely positioned operator by means of a cable connected to the male member. Spring-biased positive forces within the female assembly otherwise tending to separate the male/female members are used to reliably capture the male component. A relatively small adjustable triggering force activated by the cable moving an activating pin triggers ejecting movement of the female capturing members. The male member forms a cavity containing gripping members that slidably grip the cable. The cavity is accessible to the operator.

Abstract: A vehicle seat belt buckle has a flat tongue part with latching edges, and a socket part with spaced parallel plates defining a socket within which the tongue can be received. A latch member slides at right angles to the plane of the tongue to engage the latch formations to retain the tongue within the socket, the movement being imparted by latch member portions received in grooves of a push botton slidably guided for manual movement in the direction of insertion of the tongue. A spring urged detent retains the push button and thus the latch member in the release positions and is itself released by a portion of an ejector device when this is moved inwardly in the socket on insertion of the tongue. In a modification a spring biassed ejector prevents return of the latch member to its latching position after release of the tongue.

Abstract: A seat belt buckle having a buckle frame and a pivotal latching member mounted therein includes a single spring for biasing a push button toward an outer position and for ejecting a tongue plate from the frame when the latch mechanism is in its open position. The preferred spring is a coil spring which is loaded in tension in an extended configuration. In the preferred embodiment, the spring additionally provides biasing force to lock the latch mechanism in its latching position after insertion of the tongue plate into the buckle frame and provide biasing force to maintain the latching member in its open position prior to insertion of the tongue plate.

Abstract: An end release type of buckle for safety belt harness in vehicles and a method of assembly wherein a channel shaped elongate chassis transversely supports a latch and a latch blocking element, the latter pivotal at one end and biased toward blocking the latch. A closure plate biased to follow insertion and removal of a buckle tongue is reciprocably mounted for longitudinal movement to the web of the chassis. A release slider is provided which reciprocates to remove the blocker against its bias and to depress or open the latch. A tubular case encloses and detentably assembles the chassis and operably guides the release slider while supporting the operating bias applying elements. A cup-like cover is pressed longitudinally over the case and is detentably located and secured to said case. When not in use the latch is held open by the closure plate. When a tongue is pressed into the buckle the closure plate retreats from blocking the entry slot and the latch obeys the bias to lock.

Abstract: A safety belt buckle fitted with belt straps and two interlocking parts. These are designed for releasably connecting the belt strap. One interlocking part consists of a locked part and the other interlocking part consists of a locking part. The latter is fitted with a locking member pivoted in the locking part and able to be reset between the position releasing and the position locking the locked part. The locking member is spring loaded so as to attempt to pivot to its releasing position. A detent member is able to be reset between a detent position in which the locking member is prevented from being reset from its locking position and a releasing position in which the locking member is permitted to pivot to its releasing position. An ejector is arranged so as to eject the locked part by the action of a spring when the locking member is rest to the locking position. A link connects the detent member to the ejector. The link is loaded by a spring which attempts to move the ejector to its outer position.

Abstract: A locking device for a safety belt comprising a housing, a spring-loaded lock bolt movable in the housing, a key that can be inserted into the housing and having at least one recess fitting to the lock bolt, an unlocking mechanism, an output element of which engages, upon energization, a control-member of the lock bolt, which is moved out of the recess against the spring force and a blocking mechanism for the output element, with the blocking mechanism comprising a fastening element movable against spring force with respect to the housing, with the fastening element in its rest position releasing the path of the output element and in the displaced position blocking the path.
