An electrically releasable buckle assembly (12) for a motor vehicle restraint (10) may include latch components (18) configured to releasably engage a tongue member (14B) of the motor vehicle restraint (10), a release button (16) operatively coupled to the latch components (18), the release button (16) having a latched position in which the latching components engage the tongue member (14B) and a release position in which the latch components (18) release the tongue member (14B), an electrical energy source (32), at least one shape memory alloy component (26) operatively coupled to the release button (16), the at least one shape memory alloy component (26) responsive to heating thereof by electrical energy supplied by the source (32) to a temperature at or above a transition temperature thereof to move the release button (16) from the latched position to the release position, and means (34) for selectively supplying electrical energy from the electrical energy source (32) to the at least one shape memory alloy component (26).

A buckle device capable of displaying a locked state includes a main body unit, a latch unit, a fastening unit, an electromagnetic unit, and a control unit. The main body unit includes a main body and the latch unit includes a detachable tongue element. The fastening unit includes a bolt body interfering with the tongue element. The electromagnetic unit includes an electromagnetic module and an electromagnetic rod. The electromagnetic module controls the electromagnetic rod to interfere with the bolt body. The control unit includes a control module, a display module and a magnetic rod detection module for detecting the position of the electromagnetic rod. The control unit receives detection information of the magnetic bolt detection module and controls the display module to display a current state according to the position of the at least one electromagnetic rod.

A system and method for securing a locked-out component is provided. One embodiment slides a slidable blade of a lock out controller from a lockout position to a release position, wherein an inside connector between the slidable blade and a piston of a lock out attachment pushes the piston from a hook lock position to a hook extended position so that a hook is extended outward from the lock out attachment; coupling the hook to the locked-out component; and sliding the slidable blade of the lock out controller from the release position to the lockout position, wherein the inside connector coupled between the slidable blade pulls the piston from the hook extended position to the hook lock position, and wherein the hook is retracted substantially back into the interior of the lock out attachment so that the locked-out component that is coupled to the hook cannot be accessed by a tool.

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 buckle includes a main body part that can be coupled to a tongue that is attached to a seatbelt of a vehicle; a communication substrate to which one end of a wire harness is coupled, the wire harness passing through an opening formed on a buckle surface of the buckle; a holder configured to support the communication substrate; and a cover configured to cover the main body part, the communication substrate, and the holder. The cover includes a rib that prevents the holder from moving in an opening direction of the opening.

A seat belt for a vehicle comprises a first tongue coupled to a first webbing, the first webbing configured to cover portions of a shoulder, a chest, and an abdomen of a passenger; a first buckle coupled to the first tongue; a second tongue coupled to a second webbing, the second webbing configured to cover portions of the abdomen of the passenger; a second buckle coupled to the second tongue; and an actuator configured to upwardly pull the first tongue and the first buckle, wherein the first buckle is coupled to the second buckle; and upon a collision of the vehicle, the actuator operates to separate the first buckle from the second buckle, and the first webbing moves upward, restricting a movement of an upper body of the passenger.

Buckle assemblies for personal restraint systems and associated systems and methods are disclosed herein. In one embodiment, a buckle assembly includes a release actuator that can apply a first force and a second force to release a web connector. The release actuator is slidably coupled to a frame that includes a pair of opposing openings. A pawl is pivotally mounted to the frame via the opposing openings and includes a latch portion positioned to releasably engage the web connector. A biasing member is operably positioned between the release actuator and the pawl, and the release actuator is movable to compress the biasing member and exert the first force against the pawl. The release actuator is also movable to contact the pawl to exert the second force against the pawl. The first and second forces urge the pawl to rotate and disengage the latch portion from the web connector.

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.

A buckle device into which a tongue plate provided on a seat belt of a vehicle is to be inserted, and which detachably engages with the inserted tongue plate. The buckle device includes a hollow buckle body, an operating member configured to be operated in response to a release operation for releasing engagement between the tongue plate and the buckle device, the operating member being supported, in the buckle body, to be slidable in an insertion direction of the tongue plate, and an inertia member supported, in the buckle body, to be rotatable about a rotation center axis extending in a width direction of the tongue plate.
