Buckle assemblies and associated systems and methods for use with child seats and other restraint systems are disclosed herein. In one embodiment, a buckle assembly includes a housing having an opening shaped to receive a first tongue of a first web connector and a second tongue of a second web connector. The buckle assembly also includes a spring having a first ejector arm carrying a first magnet and a second ejector arm carrying a second magnet. A switch assembly is positioned within the housing, and insertion of the tongues into the housing to latch the buckle assembly moves the magnets toward the switch assembly to activate switches in the switch assembly and produce a signal confirming buckle engagement.

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

Disclosed is a belt with a tail clip. The belt with a tail clip includes a belt body provided with a connecting buckle and the tail clip. The connecting buckle includes a male buckle, a female buckle and a clamping device; a male buckle clamping portion and a female buckle clamping portion are clamped and connected through the clamping device; a belt fixing groove and a belt sliding through groove are formed in the tail clip; and one end of the belt body is fixed to the male buckle, and an end portion of the other end of the belt body is fixed into the belt fixing groove after the other end of the belt body passes through the belt sliding through groove and bypasses the inner connecting rod. The belt with a tail clip has advantages of convenience in belt length adjustment and good locking effect.

Web connectors for use in occupant restraint systems in a vehicle are disclosed herein. In one embodiment, first and second web connectors include first and second web receiving portions, respectively. The first web receiving portion includes a first projection at a first side and a first recess adjacent a second side opposite the first side. The first recess includes a first surface feature. The second web receiving portion includes a second recess and a second projection having a second surface feature. In this embodiment, the second recess is configured to receive the first projection, the first recess is configured to receive the second projection, and the first surface feature is configured to engage the second surface feature to resist movement between the first and second connectors during use.

An adjustment system comprises a strap and an adjustment buckle configured to adjust the strap. The adjustment buckle comprises a body defining a first through hole and a second through hole extending over the thickness of the body. A partitioning wall is fixed to the body. The partitioning wall separates the first through hole and the second through hole in a first direction perpendicular to the thickness of the body. The strap makes a loop inside the body and passes round the partitioning wall. A cover is fixed to the body and installed facing the partitioning wall. The cover and the partitioning wall are separated by a larger distance than the thickness of the strap.

A push button connector includes a first panel, a first trigger, a second trigger, and a slider. The first panel has a first pivot and a second pivot parallel to it. The first trigger includes a first connecting portion and a first buckle ring connected to each other. The first connecting portion is connected to the first pivot and can rotate around it. The first buckle ring is generally ring-shaped with a first opening. The second trigger includes a second connecting portion and a second buckle ring connected to each other. The second connecting portion is connected to the second pivot and can rotate around it. The slider is connected to the first panel. Both triggers have open and closed positions, with the buckle ring closing the opening in the closed position. The slider drives both triggers between these positions. This push button connector ensures easy operation and high safety.

A buckle for a connector having a small simple structure and a favorable productivity, and a method for assembling the same. A buckle for connector of the present invention for supporting a tongue engageably/disengageably includes a base member, a latch member, an unlocking member, a latch spring, an ejector, an ejector spring, and cover members housing these members. The base member includes first and second plates. The ejector includes: two arms; a body section between the arms that includes a pushing/moving surface for the tongue to be pushed/moved by the tongue, a support section to support the latch member, and a pushing surface to be pushed by the ejector spring; and claws formed at ends of the arms and locked with an aperture at a terminal end of the base member, the terminal end being opposite to a starting end from which the tongue is inserted.

A buckle having an excellent design property is provided. [Solution] In a buckle for a belt in which a socket member and a plug member engage with each other, a buckle 10 is formed by forming the socket member including a front face portion 25 having an approximately flat surface; a back face portion 26 provided in such a way as to face a reverse face of the front face portion 25, and forming an engagement hole 21 with which the plug member engages between the back face portion 26 and the front face portion 25; a pressing piece 28 formed in the front face portion 25 by being divided by a slit 31 formed in the front face portion 25 and pressed for releasing an engagement with the plug member inserted into the engagement hole 21 to be engaged therewith; and a hinge portion 29 formed to be thinner than the pressing piece 28, connecting the pressing piece 28 to the same surface as the surface of the front face portion 25, and serving as a base point for a displacement when the pressing piece 28 is pressed.

A safety belt buckle, which includes a buckle member, a hook, a stop member, a latch member and a release button, wherein the latch member has a tongue plate which enters a chamber of the buckle member through a lateral opening of the buckle member, and pushes the stop member to a predetermined position; when the stop member stays at the predetermined position, the hook is restricted by the stop member, and stopped at another predetermined position to engage the tongue plate, which makes the latch member unable to separate from the buckle member. By pushing the release button connected to the stop member, the hook can pivot unrestrictedly, therefore the tongue plate is no longer engaged by the hook, and the latch member and the buckle member can separate from each other.
