A buckle (100) includes a male buckle (110), a female buckle (120), and an actuating structure (130) disposed between the male buckle (110) and the female buckle (120). When the male buckle (110) and the female buckle (120) are engaged, the actuating structure (130) generates an actuating signal. When the male buckle (110) and the female buckle (120) are disengaged, the actuating structure (130) generates a disconnecting signal. A control circuit operates according to the actuating signal or the disconnecting signal, such that the control circuit is actuated more conveniently and the structure of the buckle (100) is simple.

A seat belt buckle for use in vehicles is provided. The seat belt buckle includes a base and a cover removably fixed to the base. The base includes a bottom surface, a pair of sidewalls, and a plate fixed to the bottom surface and extending laterally therefrom. The plate includes an opening having a width of or greater than about 2 inches. The seat belt (webbing) can be fed directly through the opening without the need to fold the webbing inward from its edges. The webbing can also be easily manipulated around and through the opening to avoid snagging or clogging the webbing in the buckle.

A self-locking latch assembly for a two-piece container is provided. The latch assembly has a latch hook pivotably biased in a parallel orientation to the first piece of the two-piece container, while a keeper is connected though spaced apart from the surface of the second piece of the two-piece container. The two-piece container is adapted to move between an open and closed position by sliding an open end of the larger piece over an open end of a smaller piece. During this sliding action, toward the closed position, a tapered edge of the latch hook strikes the keeper and is urged upward until the tapered edge ends, whereby the biasing of the latch hook urges it to engage the keeper in a locked condition. To unlock the latch hook, one can pivot it to a nonparallel orientation and slide the two pieces apart.

A device and system that can be used to assist actuation of a buckle release is disclosed. A device can comprise a first arm and a second arm joined by a U-shaped connecting portion. The device can also comprise a button contact feature. The device can be inserted over a buckle with the button contact feature over a buckle release button, and the device used to assist engagement of the buckle release button by a person operating the device. A system can comprise a device and various additional features or accessories.

A restraint 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 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.

Described herein is a retractable safety assistive belt assembly for use in transferring disabled or senior patients. The belt assembly includes a retractor assembly, a buckle mechanism, a latch member, a quick-release button, a strap or band member, and an optional belt clip attached to an external part of a housing. The strap or band member optionally includes measurement markers. In a related embodiment, an optional belt assembly case is provided for storage and portability of the belt assembly.

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.

Provided is a tamper guard for a child safety seat. The tamper guard comprises an upper portion configured as a hollow prism or cylinder, and a lower portion connected to the upper portion. The lower portion is comprised of a quadrilateral top face having an opening of similar cross-section to the hollow prism or cylinder, and an integral retainer located below the quadrilateral top face. The lower portion is configured to receive a buckle of the child safety seat within a space defined by the quadrilateral top face and the retainer. The retainer is configured to retain the buckle with in the space. Additionally, the upper portion and the lower portion cooperate to form a continuous opening from a distal opening of the hollow prism or cylinder to the opening of the top face, the continuous opening configured to display and allow access to a quick release mechanism.

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.
