A buckle assembly includes a first buckle member having an insertion member, a second buckle member, a first buckle latch, a second buckle latch, a plurality of resilient elements, and a locking arrangement. The locking arrangement includes at least two locking protrusions and at least one guiding member. The locking protrusions are extended from one of the insertion member and the second buckle body, and are arranged to form a locking channel between the two locking protrusions. The guiding member is extended from the remaining one of the insertion member and the second buckle body, and is arranged to be inserted in the locking channel formed by the locking protrusions so as to retain the first buckle member to be locked with the second buckle member when the first buckle latch and the second buckle latch are in the locked position.

A seatbelt buckle that includes a housing, an attracting member, an attractable element, and a plate adapted to retain a seatbelt clip within the housing. The member, the element, and the plate may be carried by the housing. The buckle is adapted so that when the member is electronically actuated, the element causes the plate to move toward the member and thereby release the clip.

This application discloses a connecting buckle with a safety switch. The connecting buckle includes a male connecting piece, a female connecting piece and a buckling apparatus; the buckling apparatus includes a buckling piece, the buckling piece is arranged in match with a sliding frame arranged on the male connecting piece, a rotating shaft is arranged on the buckling piece; the rotating shaft and the rotating holes formed on the sliding frame are correspondingly arranged, a clamping part corresponding to the buckling hole is arranged at one end of the buckling piece, an upward supporting spring is arranged between the other end of the buckling piece and the sliding frame, and a pressure stopping apparatus is also arranged on the buckling apparatus. The connecting buckle with the safety switch has the advantages that the structure is simple, accidental loosening of the connecting buckle is completely avoided, and the universality is wide.

A latch device comprises a housing unit, a disk unit, an electromagnetic lock unit, a pressing lock unit, and a detecting unit. The housing unit includes a housing, which has a pressing hole and an insertion slot. The disk unit includes a supporting rod positioned through the housing, and two vertical disks pivotally arranged to the supporting rod. The outer perimeter of the two disks is placed with a hook, a first engaging portion and a second engaging portion. The electromagnetic lock unit includes two electromagnetic mechanisms, two retractable bars connected to the two electromagnetic mechanisms, and two electromagnetic latches respectively connected to the two retractable bars. The pressing lock unit includes a pushbutton, and a button latch connected to the pushbutton. The detecting unit includes two detectors, which are disposed inside the housing for detecting the position of the two electromagnetic latches.

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.

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.

This application discloses a connecting buckle with a safety switch. The connecting buckle includes a male connecting piece, a female connecting piece and a buckling apparatus; the buckling apparatus includes a buckling piece, the buckling piece is arranged in match with a sliding frame arranged on the male connecting piece, a rotating shaft is arranged on the buckling piece; the rotating shaft and the rotating holes formed on the sliding frame are correspondingly arranged, a clamping part corresponding to the buckling hole is arranged at one end of the buckling piece, an upward supporting spring is arranged between the other end of the buckling piece and the sliding frame, and a pressure stopping apparatus is also arranged on the buckling apparatus. The connecting buckle with the safety switch has the advantages that the structure is simple, accidental loosening of the connecting buckle is completely avoided, and the universality is wide.

A safety buckle device includes a first buckle part having a partially closed space with an opening, and a second buckle part having a body, a guiding tongue, and a control key. When locking the safety buckle device, a springing detent is adapted to lock against a locking element. The control key has two recesses having different depths and arranged adjacent each other in the longitudinal direction of the control key. The detent achieves a first locking when the control key is actuated, and the detent achieves a second locking when the control key no longer is actuated, or the detent achieves a locking when the control key is not actuated. The detent is adapted to be released when the control key is actuated again, or when the control key is actuated.

A seat belt buckle for engaging a latch inserted into buckle and retained in a latched mode until released by depressing a press release button. In a locked mode, with the vehicle ignition switch ON and the latch inserted into buckle, a complementary lock is activated preventing press the release button from effecting release of latch from buckle.

Apparatus and method of locking two devices to each other through a receiver base, a pair of pivoting locking tabs, each having first and second arms extending out from a pivot point, and an insert that is partially engaged within a cavity formed by the receiver base and locking tabs. The receiver base is configured to be engageable with a first device. The insert is configured to be engageable with a second device. An optional push button assembly that has a retractable lip is engageable with the receiver base to block rotational movement of the locking tabs unless the lip of the push button is retracted. The apparatus may also include magnetic actuators and corresponding electronic switches that provide two stage locking and, optionally, provide contact state signaling to an external controller and computer to verify locked/unlocked status of the insert relative to the receiver base cavity and locking tabs.
