In a buckle device, latch rotation shafts of a latch are supported by body shaft receiving portions of a buckle body further to the device rear side than a support shaft that supports a buckle device side of a coupling member. The latch is rotated in one direction about the latch rotation shafts, such that a latch engagement portion of the latch engages with a tongue further toward the device front side than the support shaft. Such a configuration enables a rotation radius of the latch to be suppressed from becoming smaller even if the buckle device is made more compact.

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.

Disclosed is a buckle assembly having a female buckle component and a male buckle component. The male buckle component configured to mate with the female buckle component and comprising a main body, a mating guide beam, and one or more lateral arms coupled to the main body and configured to deflect about pivot points. Each lateral arm having a distal end configured to engage said female buckle component via a latching ledge of a button. Each lateral arm is shaped to define an effective length between the latching ledge and the pivot point that is greater than a linear distance between the latching ledge and the pivot point.

A latching mechanism is applied to be mounted on a webbing of a seat belt system. The latching mechanism has a tongue assembly and a slider mounted on the tongue assembly. The slider has a bridge located at a side of the tongue assembly. The webbing passes through a bottom end of the bridge and is inserted through the slider and the tongue assembly. The webbing has a shoulder belt located at a side, which has the bridge, of the latching mechanism. When the slider is located in an unlocked position, the latching mechanism is capable of freely moving along the webbing. A tension of the shoulder belt acts on the bridge for driving the slider to move from the unlocked position to a locked position, such that the webbing is clamped and locked by the slider and the tongue assembly.

A rotating buckle includes a first fixing member, a second fixing member, and a hook body. The first fixing member includes protruding posts. The second fixing member defines limiting slots and comprises a fixing portion. The fixing portion fixes the second fixing member to the first fixing member through a first resilient member. The hook body is received between the first fixing member and the second fixing member. The hook body defines a mounting hole, an inclined slot, and a receiving slot. The protruding posts are inserted through the mounting hole, the inclined slot, and the limiting slots. The fixing portion is inserted through the receiving slot. The hook body is fixed to the first fixing member through a second resilient member.

A buckle structure is adapted to connect a strap. The buckle structure has a connecting port. The connecting port has a connecting member for connecting the strap. An extending portion extends from a side of the connecting port. The extending portion has an opening for the strap to pass through. The strap passes through the opening to enter the connecting port and connect the connecting member.

Disclosed is a toggle lever closure, including a first closure element, a second closure element which is pivotable about a first pivot axis with respect to the first closure element in order to close the toggle lever closure, and a tensioning element which is connected in an articulated manner to the second closure element about a second pivot axis spaced apart from the first pivot axis. At least one magnetic device acts between the first closure element and the second closure element and/or between the first closure element and the tensioning element.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

An apparatus for assisted buckle release employing a generally C-shaped, V-shaped, or U-shaped assistive device adapted to depress a buckle's release button, such as a button typical of a child car seat restraint harness, and thereby assist in unlocking the buckle.
