A buckle assembly includes a first buckle, a second buckle, an operating portion, a locking component and a resilient portion. The first buckle includes an inserting end whereon an engaging portion is formed. An installation slot is formed on the second buckle for receiving the inserting end. The operating portion is disposed on the second buckle, and the locking component is fixedly connected to the operating portion. The locking component can be locked with or released from the engaging portion. The resilient portion is biased to separate the inserting end from the installation slot. The operating portion is operated to drive the locking component to release from the engaging portion. The inserting end can be separated from the installation slot by the resilient portion, so as to unlock the first buckle and the second buckle. The buckle assembly has advantages of easy operation and simplified structure.

A harness system is provided and includes an upper buckle, an upper strap and a restraining assembly. The upper strap includes shoulder portion and a waist portion divided by the upper buckle. A through slot is formed on the upper buckle. The restraining assembly includes an anti-sliding structure, a beam structure disposed on the upper buckle and a stopping component. The through slot includes a first portion and a second portion divided by the beam structure and respectively adjacent to the shoulder portion and the waist portion. The upper strap passes through the first portion of the through slot from bottom to top and passes through the second portion of the through slot from top to bottom. The stopping component is detachably disposed on the shoulder portion and configured to abut against the upper buckle for restraining a sliding movement of the upper buckle relative to the upper strap.

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.

A harness system includes an upper buckle, an upper strap and a restraining assembly including an anti-sliding structure and a beam structure. A through slot is formed on the upper buckle. The upper strap passes through the through slot. The beam structure is slidably disposed on the upper buckle. The anti-sliding structure is disposed on at least one of the beam structure and a wall of the through slot. The upper strap is engaged by the anti-sliding structure for restraining a sliding movement of the upper buckle relative to the upper strap and toward a shoulder portion when the upper strap is forced to drive the beam structure to slide relative to the upper buckle and toward the wall of the through slot.

A safety restraint for a vehicle includes a belt, a connecting structure that is connected to the belt, a buckle housing that includes a connector opening for insertion of the connecting structure, a latch assembly that is configured to retain the connecting structure in the connector opening, and a release button that is connected to the buckle housing and is configured to cause the latch assembly to release the connecting structure when the release button is operated. A first indicator area is located on the buckle portion adjacent to the connector opening. A second indicator area is located on the release button. A third indicator area is located on the release button and is surrounded by the second indicator area.

A male buckling component for a magnetic buckling assembly. The male buckling component comprises a male locking portion having a column structure. The male locking portion comprises an abutting structure at an end of the column structure, and a male engaging structure adjacent to the abutting structure and formed around a circumference of the column structure. An installation chamber is formed inside the male locking portion, and a male magnetic component is installed into the installation chamber so that the male magnetic component is inside the male locking portion of the male buckling component.

A female buckling component for a magnetic buckling assembly. A female locking portion comprises at least one resilient arm and at least one engaging head integrally formed with the at least one resilient arm. The at least one resilient arm drives the at least one engaging head to move when the at least one resilient arm is resiliently deformed. The female buckling component also comprises an installation chamber inside a middle portion of the female buckling component, a female magnetic component installed in the installation chamber, and at least one operating component movably disposed on the female buckling component and coupled to the at least one resilient arm of the female locking portion to resiliently deform the at least one resilient arm and thereby move the at least one engaging head.

A buckle with a first buckle part and at least one second buckle part. The first buckle part has a first buckle main body and a receptacle which is hook-shaped, seen in at least one section, and formed rigidly on the first buckle main body. The second buckle part has a second buckle main body with an inherently rigid hook-in part for hooking into the receptacle of the first buckle part, and the first buckle part additionally has at least one bolt. The hook-in part has a central web and two side parts protruding on mutually opposite sides from the central web, and each of the side parts is delimited by a respective front edge, and the front edges of the side parts are oriented extending obliquely away from each other at least regionally from a direction of the central web, preferably running at least regionally in a V-shape relative to each other.

A webbing-buckling device of a multi-point seat belt system has a buckle assembly and a tongue assembly. The buckle assembly has a buckle base having a first frame portion and a webbing-locking member slidably inserted through the first frame portion. The tongue assembly is disposed on the buckle assembly and has a tongue base having a second frame portion and a webbing-fixing member slidably inserted through the second frame portion. One of two webbings is inserted between the first frame portion and the webbing-locking member, and the other webbing is inserted between the second frame portion and the webbing-fixing member. Alternatively, the webbing-buckling device has a buckle assembly and two tongue assemblies disposed on the buckle assembly. Each tongue assembly has a tongue base having a second frame portion and a webbing-fixing member inserted through the second frame portion. The webbings are inserted through the tongue assemblies.
